【合作探究】                                              

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。

_____people,_______time._______money.______work. ______water._________friends.

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”，其反义词为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。
