The Use of PPT in Class
With the advance of educational technology, the use of PowerPoint (PPT) is becoming increasingly popular in class. However, it is a controversial issue that has raised wide public concern. In my view, we should hold a cautious attitude toward the widely used PPT in class.
On the one hand, a well-designed PPT definitely enhances teaching efficiency in that all the knowledge has been prepared beforehand. What’s more, many delicately designed PPTs are quite attractive to students. But on the other hand, we have to admit potential problems exist with the overuse of PPT in class. For example, an excessively informative class would be overloaded for the learners, resulting in students’ distraction from the key points. Moreover, teachers’ heavy reliance on PPT is another concern. It is said that many teachers don’t know how to teach without PPTs..
As a result, teachers are supposed to take both the teaching efficiency and students’ learning outcome into consideration, and make a good balance between them. After all, all the use of technology, including PPT, should respect the educational principles and students’ real needs.

Part IV Translation
Tea has been in existence for 5000 years. According to legend, a few leaves of wild trees fell into his pot while Shen Nong was drinking boiling water, and the boiling water immediately released a pleasant fragrance. He took a few sips, feeling quite refreshed. Thus tea was discovered.
Since then, tea has become popular in China. Tea plantations spread all over the country, and tea merchants became rich. Expensive, elegant tea sets have becomea status symbol.
Today, tea is not only a healthy drink, but also an integral part of Chinese culture. More and more international tourists learn about Chinese culture while tasting tea.
