Gestures aren't the only area in which the unwary traveler can get tripped up. Foreign cultures adhere to different business customs and behavior. For example, Caffeine junkies should restrain themselves in the Middle East. "Three cups of tea or coffee is usually the polite limit in offices and during social calls," counsels "Travel Pak," a free publication of Alia, the Royal Jordanian Airline. "Butif your host keeps going, you also may continue sipping. If you're had your fill, give your empty cup a quick twist a sort of wiggle--as you hand it back.That means "No more, thank you." Middle East visitors also should not be surprised "if others barge right into the office in the middle of your conversation with the person you are seeing," notes "Travel Pak." An old Arab custom calls for keeping an "open office." The British, however,consider it impolite to interrupt a visitor, even after all business has been transacted. The commercial caller is expected to be sensitive to this point,know when to stop, and initiate his or her own departure. In Japan certain guests at evening business gatherings will leave early. They should be allowed to leave without effusive goodbyes. The Japanese consider formal departures to be disruptive in such cases and disturbing to remaining guests. In Scandinavia and Finland business guests may be asked to shed their clothes and join their hosts in a sauna. The invitation is a sign that a good working relationship has been established. In the Arab world, the word"no" must be mentioned three times before it is accepted. In contrast, it is considered good business manners to make many and long efforts to pick up the check. In the People' s Republic of China, gift giving is considered an insult, says Patrick J. Lewis, President of Club Universe, a Los Angeles tour operator. "If you want to give someone a gift, make sure it's modest in value. This will not be considered offensive. but it may be declined," The Chinese manner of expressing friendship and welcome is to clap. Lewis adds. "You may be greeted with clapping when entering a factory,hospital, commune, or school. Politeness dictates that you respond with applause, even though it may seem like you're clapping for yourself." 答案解析
Teaching children to read well from the start is the most important task of elementary schools. But relying on educators to approach this task correctly can be a great mistake. Many schools continue to employ instructional methods that have been proven ineffective. The staying power of the "look-say" or "whole-word" method of teaching beginning reading is perhaps the most flagrant example of this failure to instruct effectively. The whole-word approach to reading stresses the meaning of words over the meaning of letters, thinking over decoding,developing a sight vocabulary of familiar words over developing the ability to unlock the pronunciation of unfamiliar words. It fits in with the self-directed, "learning how to learn" activities recommended by advocates ( 倡导者) of "open" classrooms and with the concept that children have to be developmentally ready to begin reading. Before 1963, no major publisher put out anything but these "Run-Spot-Run" readers. However, in 1955, Rudolf Flesch touched off what has been called "the great debate" in beginning reading. In his best-seller Why Johnny Can't Read, Flesch indicted (控诉) the nation's public schools for miseducating students by using the look-say method.He said--and more scholarly studies by Jeane Chall and Rovert Dykstra later confirmed--that another approach to beginning reading, founded on phonics (语音学), is far superior. Systematic phonics first teaches children to associate letters and letter combinations with sounds; it then teaches them how to blend these sounds together to make words. Rather than building up arelatively limited vocabulary of memorized words, it imparts a code by which the pronunciations of the vast majority of the most common words in the English language can be learned. Phonics does not devalue the importance of thinking about the meaning of words and sentences; it simply recognizes that decoding is the logical and necessary first step. 答案解析
For reasons that are deeply rooted in culture and tradition, men significantly outnumber women inmathematics-based careers. As students progress through the mathematics courses, girls and boys show littledifference in ability, effort, or interest in mathematics until adolescent years when course and career choices begininfluencing school effort. Then, as social pressure increases and career goals are formed, girls' decisions to reduceeffort in the study of mathematics progressively cut them off from many professional careers in the future. Many girls drop mathematics in high school or in the transition to college. Others drop out later. Womenperform virtually as well as men in college mathematics courses, but beyond the bachelor's degree women drop outof mathematics at twice the rate of men. Women now enter college nearly as well prepared in mathematics as men,and 46 percent of mathematics baccalaureates (学士学位）go to women. Despite this record, only 35 percent ofthe master's degrees and 17 percent of the Ph. D degrees in the mathematical sciences are earned by women. Overall, women receive approximately one third of university degrees in science and engineering. The highestpercentages of women are found in those sciences with the least mathematical prerequisite: psychology, biology,and sociology. The lowest percentages of women enter fields requiring the most mathematics, namely, physics,engineering, economics, geo-science, and chemistry. Evidence from many sources suggest that it is differences incourse patterns rather than lack of ability that matter most in limiting women's access to careers in mathematicallyintensive sciences.Widely reported studies concerning the high percentage of boys among mathematical prodigies ( 天才. —those who at age 12 perform at the level of average college students—often convey the impression that genderdifferences in mathematics are biologically determined. But evidence from the vast majority of students showsalmost no difference in performance among male and female students who have taken equal advantage of similaropportunities to study mathematics. Inferences ( 推论）from very exceptional students—child prodigies—meanlittle about the performance of the general population. 答案解析

Health experts have called adolescents to avoid salty diets, warning that such diets were capable of causing hypertension (高血压), as they grow older. The experts, who spoke in Lagos during cardiovascular (心血管的) grass root programme organised by Chike Okoli Foundation in collaboration with Lagos State Ministry of Education for over 1,000 senior secondary students (SSS) of Dairy Farm Senior Secondary School, Lagos, also urged adolescents to be mindful of their lifestyles as whatever they do today have future implications on their heart. The grass root programme is an annual event aimed to educate, create awareness and screen students in secondary school of heart related diseases in memory of Chike Okoli, who died at the age of 25 of cardiovascular disease. This year, the programme is targeting over 10,000 students in Lagos public schools. Public health physician and resident doctor at the university of Lagos Teaching Hospital (LUTH), Dr Idiakhoa Iyare, who was one of the guest lecturers for the programme, said the importance of the cardiovascular grass root programme could not be over emphasised as exposing young ones to implications of their lifestyles would save them from deaths and sufferings that could result from future cardiovascular diseases. "If we call hypertension a silent killer, it means that it is going to be silent for along time," Iyare said. " But if we could make the children get aware earlier and start focusing on healthy ways of living while they are much younger, it would be easier for them to modify their habits while they are young." Programme Coordinator of Chike OkoliFoundation, Mrs. Beaty Alfred, said that the programme was important to raise the health status of students in Lagos schools because "we believe that they are ignorant of the implications of some of their lifestyles," adding that "we want to catch them young."The students were taken through series of lectures on the causes, implications and how to avoid hypertension by various experts from LUTH. Blood pressures of the students were also measured. Iyare added that hypertension is different from high blood pressure, which could arise from increased activities. The public health physician said:"Hypertension is a persistently elevated blood pressure. That means that the blood pressure is greater than 140-millimetre mercury systolic blood pressure and greater than 90-millimetre mercury diastolic blood pressure." 答案解析
Secrets of Grade-A ParentsHelping your child get ahead at school starts at homeA）When Carey Graham started Grade One, he got a very special teacher. “She recognized my passion for learning.” says the now 20-year-old. “Every morning we’d sit down with workbooks and do writing and math exercises. And any time during the day, she could always be counted on to read to me. She always encouraged me to learn all I could about everything.” This extraordinary teacher was his mom, Jeanne Lambert, who homeschooled Graham until high school. He’s now in his second year in the University of Toronto’s Peace and Conflict Studies program, having received a provincial “Aiming for the Top” scholarship. Graham is considering a law degree or a master’s in political science down the road. He attributes his academic success to the foundation laid by his parents.B）“You can’t be a parent without being a teacher, ” says Bruce Arai, a professor in the Department of Sociology and Anthropology at Wilfrid Laurier University in Waterloo, Ontario. “Perhaps the most important teaching in a child’s life is done by his parents, not by some professional with certificates, ” he says. Homeschooling isn’t about sitting your kids down in the kitchen and teaching them in the formal sense, says Aral, but about “making sare the resources and opportunities for learning are available to them. ” And that, any parent can do. Here, then, are some methods that parents who would never consider homeschooling can pick up from those who do.Lesson 1 Think Outside the ClassroomC）When homeschooler Kerri Paqueue, a mother of six, was building a house in Lansdowne, she saw it as a learning opportunity. “They learned math as we measured. about soil as we dug the foundation, about water while we did the plumbing, and about electricity when we did the electrical work. My children make the subjects come alive as much I do. ” says Paquette. Her kids, aged three to13, continue to view the world as their classroom. They study food and plant growth through their organic garden. They learn about cows by talking to the neighboring farmers. And they learn math, measuring and science while helping Paquette cook. “The other day my nine-year-old, Maddison, started learning a new educational computer program. ne section on fractions was all new, but she knew it from when we bake. ” Every activity, says Paquette, can include a lesson.Lesson 2 Eliminate Learning LimitsD）A teacher with a class of 25 students can’t continue a unit on, say, the body just because one child is still keen—but you can. “We don’t have a time flame that restricts our investigations, and we don’t have a dally schedule, ” says Linda Clement, who homeschools her two daughters in Victoria. When her l4-year-old showed an interest in the human body, the curious student read dozens of relevant books and surfed web sites. Janet’s curiosity took her in all sorts of directions：a dictionary of poisons and antidotes, an encyclopedia of medicine, books about human personality and much more. The benefit to your child goes beyond a thorough knowledge of a subject. Studying deeply a topic builds independent research skills and a love of learning. “If my children are interested in a subject, ” says Clement, “we can go as far into the subject, answering as many questions as they have. for as long as is necessary. This freedom encourages their investigations. ”Lesson 3 Teach Your Kids Their WayE）Some children are visual learners(they absorb best when they see something), some are auditory(they need to hear it), some are kinesthetic(they need hands-on experience)and some are a combination. Uncovering how your child learns best will increase your effectiveness in helping him or her with schoolwork. Unsure of your child’s learning style? Ask his teacher.F）The way Melissa Cowl’s six children, aged three to 15, pick up on math highlights the great differences in learning styles. “Our ten-year-old, Matthew, needs everything in black and whim：Tell him what to do and how to do it, and it’s done, ” says the mother. “He had a math text that was too colorful, with a layout that was difficult to follow. I switched to a text that was more step-by-step, more concrete. Now he does math tests with no trouble. ”“Our eight-year-old, Ryan, however, is very hands-on. For math, he uses a variety of colorful pens to figure out things like addition and fractions. He needs to see it and feel it. Not one of my kids learns the same way as the others. ”Lesson 4 Let Them See You LearnG）One of the best parts of homeschooling is that you can continue your own education—and your kids can see you doing it and pick up on your love of learning the same principle can be applied by any parent. “Learning never ends,” says Julia Goforth, a homeschooling mother of four. “We try new things all the time, whether I’m reading something new or we’re all tasting foods we’d never normally eat.” Reversing the roles also has benefits, giving kids a sense of pride in their own newfound knowledge. “Today my l2-year-old daughter, Denise, explained to me how she figured out a math problem. She’d wound up with the right answer, but I didn’t understand how she managed it,” says homeschooler Gina Rozon of La Ronge. Sask. “Our kids are teaching us all the time.”H）Learning doesn’t always go smoothly, for kids and adults alike, which is why it’s important for children to see their parents struggle with something new. “My children watched me turn my life around by trying new things.” says Goforth. “I went from being a fearful, stay-at-home mom to an adventurous artist’s model and public speaker. Learning to belly dance and play the violin is on my to-do list this year. ”Lesson 5 “Own” Your Children’s EducationI）“Helping them isn’t about showing your kids how to do the work. It’s about being genuinely interested and having regular conversations about what they’re learning,” says J. Gary Knowles, a professor at the Ontario Institute for Studies in Education. Rozon has many suggestions for how to get more involved. “Get to know the teacher. Discuss ways to design the assignments to your child’s learning style. Spend time in the classroom. Ask for outlines of unit studies so you can find additional materials at the library or through videos. Read your child’s textbooks：If you work a few pages ahead, you’11 be able to help them with problems they encounter. ”Reading is another must, says Rozon. “Even after your children can read themselves, hearing somebody else read aloud is important. We nearly always bring a book wherever we go；we read for at least a half hour before bedtime. ”The more engaged a parent is, the more the child benefits, adds Bruce Arai. “The evidence is clear： Parental involvement is one of the most important factors in school success. The hours children spend in class are but one element of their education” 答案解析
How to Visualize Your SuccessA）Have you ever heard of visualization (可视化)? Of course you have. Everybody’s heard of visualization and everybody partakes in it whether they realize it or not. How it works though is an altogether different matter. I want to take a closer look today at the mechanics of why visualizing works without necessarily delving into concepts and theories that cannot be proven.B）The brain has great difficulty in distinguishing between what’s true and what’s imagined. There is an oft-cited (经常被引用的) example of an experiment conducted by Australian Psychologist, Alan Richardson. He took some basketball players and split them into 3 equal groups. One group was told to practice their free throw technique twenty minutes per day. The next group was told to spend twenty minutes per day visualizing, but not attempting free throws, and the final group wasn’t allowed to either practice or visualize. At the end of the test period the group that had done nothing remained as they were, but both the other groups showed similar degrees of improvement. The people who only visualized playing basketball were able to perform almost as well as the ones who had actually practiced. “How can that be so?” Firstly, the people practicing would miss some shots. Each time they missed they had in effect, practiced how to miss. The people that were visualizing would be hitting every basket so they were building up the feelings and memory of how to be successful.Forging a Path through a MeadowC）Imagine walking home from a new job. You suddenly realize that there is a meadow of long grass that will cut 20 minutes off your walk. If you live in New York you’re going to need a great imagination for this one. The first few times you can barely see which way you had walked the previous ay. However, after 10 or 20 times you can clearly see a pathway starting to form, and after 100 times all the grass is worn away and there’s a farmer with a shotgun and large dog waiting for you at the end. Let’s presume our gun-toting friend is a big softie and he allows you to use that route as long as you want. What are the odds that next time you try a slightly different direction? Slim to none would be my guess. After all, you know this way works and you have a lovely easy path.D）On the other hand, if Farmer Giles starts taking pot shots at you and sportingly lets the dog try and shoot you too, before releasing it to sink its gnashers into your rear end, then you’ll probably find a new way home once you’re released from hospital. The next time you’re walking home you opt against reacquainting yourself with Fido and spot another meadow further along the road. The same process then begins to take place only this time the original path you made has started to grow back.How We Create a Path in Our MindE）That is what happens when we form thoughts in our mind. The first time we have a new thought it is a weakling(虚弱者) of a thought that has sand kicked in its face by stronger thoughts and beliefs. Each time you re-think it though it grows in strength as the physical pathway becomes more and more well-defined. Not only that, but if it is a belief that contradicts one you already hold, the older belief starts to atrophy and die.F）This also explains why we have the same thoughts over and over again and why people have difficulty snapping negative loops (循环) of thinking. The pathway has been established and it’s just easier to continue following it than trying to think about something new and form a new connection in the brain.Making Visualization Work for YouG）Visualization is an incredibly successful and simple way of speeding up the process by fooling the unconscious into believing that you have already done something before you have. That’s what the basketball visualizers were doing, fooling their own unconscious into thinking they know how to hit basket after basket. Of course this in and of itself will not turn you into an NBA star, you do actually have to practice as well, but it will help you succeed more quickly.H）All you need to do to be successful at this is to visualize yourself doing something, as you would like to do it. Profound stuff, huh? Seriously though, that is all there is to it. How long you do it each day will affect the speed of change and it’s really not advisable visualizing your success for 20 minutes per day and then spending 10 hours worrying about failing and replaying negative stuff in your head. It kind of defeats the object. You can also incorporate the “fake it till you make it” method in with your visualization to help speed up the process. This is simply a matter of pretending you are already proficient at something before you really are. Again, it’s simply a way of tricking your unconscious and getting it to do what you want it to do.I）Some people have difficulty with this process and tell me it’s being unrealistic. Well yeh, maybe they’re right, but who cares? If you want to be shackled by the chains of realism then go ahead, knock yourself out, but let me tell you this. There are few highly successful people out there that haven’t used this method or visualization at one time or another. In fact, successful people don’t care too much for reality; it just gets in the way and slows them down. What about you? 答案解析

A) The effect of television on children has been debated ever since the first sets were turned on. Now three new studies find that too much tube time can lower test scores, retard learning and even predict college performance. The reports appear in the July issue of the Archives of Pediatrics & Ado-lescent Medicine.　　B) In the first report, researchers studied the effect that having a TV in a child's bedroom can have on third graders. "We looked at the household media environment in relation to 　　academic achievementon mathematics, reading and language arts tests," said study author Dina L.G. Borzekowski, an as-sistant professor at Johns Hopkins Bloomberg School of Public Health.　　C) Borzekowski and her colleague, Dr. Thomas Robinson of Stanford University, collected data on386 third graders and their parents about how much TV the children watched, the number of TV sets, computers and video game consoles in the household and where they were. They also collected data on how much time the children spent using the different media, as well as the time spent doing homework and reading. The researchers found that the media in the household, where it is and how it is used can have a profound effect on learning. "We found that the household media environment has a very close association with performance on the different test scores," Borzekowski said.　　D) "A child who has a TV in his or her bedroom is likely to have a score that is eight points lower on a mathematics test compared to a child who doesn't have a TV in the bedroom," she noted. These children also scored lower on the reading and language arts tests. However, children who have ac-cess to a home computer are likely to have higher scores on each of the tests compared with children who don't have access to a home computer, Borzekowski noted.　　E) The reasons why TV has this negative effect are not clear, Borzekowski said. "When there's TV in the bedroom, parents are less likely to have control over the content and the amount watched," Borzekowski said. "They are also unable to know how early or how late the set is on. This seems to be associated with kids' performance on academic tests." Borzekowski believes that content and the time the TV is on may be the primary reasons for its negative effect. "If the TV is in the family room, then parents can see the content of what children are watching," she said. "Parents can choose to sit alongside and watch, or turn the set off. A simple and straightforward, positive parenting strategy is to keep the TV out of the child's bedroom, or remove it if it's already there."　　F) In the second report, Dr. Robert J. Hancox from the University of Ot ago in Dunedin, New Zealand, and colleagues found, regardless of your intelligence or social background, if you watch a lot of TV during childhood, you are a lot less likely to have a college degree by your mid-20s. In their study, the researchers followed 1,037 people born in 1972 and 1973. Every two years, between the ages of5 and 15, they were asked how much television they watched. The researchers found that those who watched the most television during these years had earned fewer degrees by the time they were 26."We found that the more television the child had watched, the more likely they were to leave school without any qualifications," Hancox said in a prepared statement. "Those who watched little television had the best chance of going on to university and earning a degree."　　G) Hancox's team found that watching TV at an early age had the most effect on graduating from college. "An interesting finding was that although teenage viewing was strongly linked to leaving school without any qualifications, it was earlier childhood viewing that had the greatest impact on getting a degree," he said. "This suggests that excessive television in younger children has a long-lasting adverse effect on educational performance."　　H) In the third paper, Frederick J. Zimmerman and Dr. Dimitri A. Christakis from the University of Washington report that, for very young children, watching TV can result in lower test scores in mathematics, reading recognition and reading comprehension. "We looked at how much television children watched before age 3 and then at ages 3 to 5," Zimmerman said. "We found that for children who watched a small amount of TV in the earlier years, there was co nsider able beneficial effect compared to children who watched a lot of TV."　　I) For children aged 3 to 5, the effect was not as clear, Zimmerman said. "There were some beneficial effects of watching TV on reading, but no beneficial effects for math or vocabulary," he noted. "The worst pattern was to watch more than three hours of TV before age 3. Those kids had a significant disadvantage compared to the other kids." Parents should follow the American Academy of Pediatrics recommendation, which is no TV for children under 2, Zimmerman said. "Personally, I feel the cutoff should be children under 3, because there is just not any good content for children under 3."　　J) One expert believes that TV can have both positive and negative effects, but it all depends on what children are watching. "Content matters," said Deborah L. Line barger, an assistant professor at the University of Pennsylvania, who co-authored an accompanying editorial. "Educational content has been found to be related to performance on school readiness tests, higher grades when they are teen-agers, whereas, non-educational content tends to be associated with lower academic performance."　　K) Another expert agrees. "TV watching takes up space that could be used by more useful things," said Dr. Christopher P. Lucas, a clinical coordinator at the Early Childhood Evaluation and Treatment Program at the New York University Child Study Center. "TV is not necessarily toxic, but is some-thing that has to be done in moderation; something that balances the other needs of the child for healthy development."　　L) Lucas puts the responsibility for how much TV kids watch and what they watch squarely on parents. "The amount of TV watching certainly has a link with the reduced amount of time reading or doing homework," he said. "The key is the amount of control parents have in limiting the amount of access. Get the TV out of the bedroom; be aware of what is being watched; limit the amount of TV watching." 答案解析
