☆教材解读☆
1.Later that day,Brian,Danny and I went for a walk around our neighbourhood.?

See you later.再见。
Later in the month,my father will go to Beijing.这个月的晚些时候,我爸爸将会去北京。
She went to Shanghai a week later.
一周之后,她去了上海。
【拓展】　later 的其他用法:

(2)sooner or later迟早。

【拓展】　around作副词,意思是“大约”。

她大约早上八点去上学。
2.I think it’s our duty to protect the environment.?
it是形式主语,真正的主语是to protect the environment,这种句式比较常见。当不定式作主语时,一般用代词it作形式主语,把真正的主语放在后面,也就是“It +be +adj.+to do sth.”,意思是“做某事是……”。
It is relaxing to listen to music.
听音乐令人放松。
It’s no use shouting.喊也没用。
3.Some hazardous waste is poison—it makes people sick.?
make sb sick是 “make +宾语 +形容词”结构,意思是“使某人处于某种状态”,其中 make是使役动词,意思是“使”,形容词sick 作宾语补足语。
They made the teacher angry.
他们使老师生气了。
【拓展】　 (1)“make +宾语 +不带to 的不定式”意思是“让某人做某事”。

StepⅥ.Complete Let’s Do It!
Ask the students to read the passage again and again to finish No.1 and No.2 by themselves.

StepⅦ.Task
GROUP WORK:Let’s Do It! No.3
Ask students in groups to come to the front of the classroom,and they can present their ideas about hazardous waste.
