Video 4 is an analysis of Paragraph 5 of Unit 3 Text A: 

Many are using smartphones, not only to create their own dialects when texting, but also to do more serious work, such as practicing foreign languages and analyzing scripts from their theater classes. In a university class on the history of American radio, students use smartphones to record their own radio shows. The course instructor said, "It's adding to students' sense of excitement about the subject." Professors have been encouraged to tape their lectures and post them online. "We realized there might be some potential for a device that could get attention and encourage sophisticated thinking," says one leading university director.

In the video, the teacher explains the relations between sentences that make up the paragraph. Two points are made in the video: 1) recognizing the chain of topic word; 2) identifying the types of information presented by the successive sentences, i.e. reiteration, illustration, and extension.

Video 5 is an analysis of Paragraph 6 of Unit 3 Text A: 

For most undergraduates, non-stop Internet connectivity is the fuel of college life. More than just toys, these instruments are powerful tools for the storage and management of virtually every kind of information. And as more people around the world adopt these instruments, they are becoming indispensable. So, students should use the wonders of the Internet to do homework, review lecture outlines, take part in class discussions and network online with their friends. But in doing so, students must remember to regulate and balance their time. Too much time online can mean too little time in real-life studying or exercising or visiting with friends.
