　　范文：

　　The use of PowerPoint is becoming increasingly popular in class. We can see many teachers presenting to their studdents necessary teaching materials with the help of Power?Point, which has become the most common subsidiary teaching method throughout the globe.

　　The reasons why teachers enjoy using PowerPoint while teaching instead of writing on those traditional and old-fashioned blackborads lie in the following three re?spects. To begin with, using PowerPoint to present knowl?edge can save both teachers and students plenty of time in class. Furthermore, teaching through PowerPoint is so con?venient for lecturers that they can effortlessly and rapidly show the knowledge that needs learning through just sever?al taps at the remote-controller. Besides, PowerPoint gener?ally has more storage of information because, theoretically, there is almost no litmit of digital space for this slide show presentation program on computers.
