Cut unnecessary words--a good rule of thumb is to cut paragraphs down to sentences, sentences into phrases, and phrases into keywords. Limit the number of words and lines per slide. Try the Rule of Five-five words per line, five lines per slide. If too much text appears on one slide,use the Auto Fit feature to split it between two slides. Click within the placeholder to display the Auto Fit Options button (its symbol is two horizontallines with arrows above and below., then click on the button and choose Split Text between Two Slides from the submenu.

style=color: rgb(51, 51, 51); font-family: "Microsoft YaHei"; white-space: normal; background-color: rgb(250, 250, 250);/F． Capitalizing the first letter of eachword is good for the title of slides and suggests a more formal situation than having just the first letter of the first word capitalized. In bullet point lines, capitalize the first word and no other words unless they normally appear capped. Upper and lower case lettering is more readable than all capital letters. Moreover, current styles indicate that using all capital letters meansyou are shouting. If you have text that is in the wrong case, select the text, and then click Shift+F3 until it changes to the case style that you like. ClickingShift+F3 toggles the text case between ALL CAPS, lower case, and Initial Capital styles.

style=color: rgb(51, 51, 51); font-family: "Microsoft YaHei"; white-space: normal; background-color: rgb(250, 250, 250);/H) Keep the background consistent. Simple,light textured backgrounds work well. Complicated textures make the content hard to read. If you are planning to use many clips in your slides, select a white background. If the venue of your presentation is not adequately light-proof, select a dark-colored background and use any light color for text.Minimize the use of "bells and whistles" such as sound effects,"flying words" and multiple transitions. Don't use red in any fonts or backgrounds. It is an emotionally overwhelming color that is difficult to see and read.

The audience can then immediately pick up the relationships.
