◆适时点拨，释疑小结
1.辨析：more，less 和fewer
more是much，many的比较级，意为“更多的，较多的”，修饰不可数名词或可数名词。
less是little的比较级，意为“较少的，更少的”，只能修饰不可数名词。
fewer是few的比较级，意为“较少的”，修饰可数名词。
2. pollution意为“污染；污染物”，为不可数名词。
Eg. air pollution 空气污染noise pollution 噪音污染
拓展：pollution的动词形式为pollute，意为“污染”，其过去式为polluted，现在分词形式为polluting。

3. danger 名词，意为“危险；威胁”。
in danger“处于危险之中”，其反义短语为out of danger，意为“脱离危险”
拓展：danger的形容词形式为dangerous，意为“危险的”。
4. future 名词，意为“将来，未来”。
拓展：in the future将来，未来in future 以后；今后
5. 辨析：on the earth 和on earth
on the earth 意为“在地球上”
on earth 作“到底；究竟”讲时，常放在what，when 等疑问词之后，以加强问句的语气；作“当今；世界上”讲时，用于最高级之后，加强语气；作“一点儿也不”讲时，用于否定词之后，加强否定的语气。
Eg. What on earth do you mean? 你究竟是什么意思？
He said, ― I’m the happiest man on earth.‖他说：“我是世界上最幸福的人。
”
It’s no use on earth.这一点儿也没有用。
6. play a part in 参与（某事）
◆课堂训练，当堂检测
I用there be 或者have的适当形式填空。
1. an English speech contest tomorrow.
2 you any questions?
3. no schools in this village 20 years ago.
4. She a car and a house in 10 years. But now she
nothing because she no money.
5. some students and a teacher in the classroom.
6. They a lot of housework to do every day.
II用所给词的适当形式填空
