Presentation
1.To save energy, we should ______ the lights when leaving a room.
A. turn on
B. turn off
C. turn up
B
答案：B
解析：根据环保主题，"离开房间时关灯"是节能行为，turn off 表示关闭。干扰项turn on（打开）和turn up（调高）不符合语境。
【课堂练习】
2.Plastic bags cause serious ______ to the environment.
A. pollution
B. solution
C. reduction
A
答案：A
解析：pollution（污染）是环保单元核心词汇，与"塑料袋危害环境"直接相关；reduction（减少）是积极行为，不符合句意。
【课堂练习】
3.The teacher kept us ______ about green actions for 20 minutes.
A. talk
B. talking
C. to talk
B
答案：B
解析：考查宾语补足语用法。keep sb. doing sth. 表示"让某人持续做某事"，此处talking作宾补。to talk（不定式）不用于keep结构。
【课堂练习】
4.______ terrible the water pollution is in this river!
A. What
B. What a
C. How
C
答案：C
解析：感叹句结构重点。How + adj. + 主语 + 谓语! 修饰形容词terrible，What需接名词短语（如What terrible pollution!）。
【课堂练习】

—______ Try reusable ones to reduce waste.
A. That's great!
B. You'd better not.
C. No problem.

A. fill
B. filling
C. filled
D. to fill

A. turn off
B. turning off
