| Unit 15 We’re trying to save the manatees. Section B & Review 3 |
主编：黄冈中学英语集体备课组
Step 1 The introduction to the text
It’s everyone’s duty to protect the environment. As middle school students, how can we become greener persons？ First of all, we should save energy, such as turning off lights before leaving and reducing the time to watch TV or surf the Internet to save electricity, turning off the tap after washing to save water. What’s more, we should produce as little waste as possible. Using both sides of paper is a good choice. We should reuse old books instead of throwing them away. Don’t use cups or chopsticks that can be used only once. Besides these, we shouldn’t pollute the environment. Riding a bike or walking to school is a good way to prevent air pollution. While shopping we are supposed to take cloth bags or baskets instead of plastic bags.
