B：3. And many fish are dead.
A：What a pity! 4.
B：It comes from some factories.

A. What do you do then?
B. Are there a lot of fish in the river?

1. F
2. B
3. D
4. E
5. A

1. 上句询问居住地点，F选项“我住在一个小镇上”符合语境，且与下句“我们镇上有一条小河”衔接自然。
2. 根据答句“No，there aren't.”可知，上句是Are引导的一般疑问句，B选项“河里有很多鱼吗？”符合要求。
3. 上句用“Why”提问，回答需用Because开头，D选项“因为里面有太多垃圾了”既符合句式要求，又能衔接下句“很多鱼死了”。
4. 根据答句“It comes from some factories.”可知，上句是询问垃圾的来源，E选项“垃圾来自哪里？”符合语境。
5. 根据答句“We move some factories away.”可知，上句是询问采取的措施，A选项“那你们做了什么？”符合要求。

五、阅读短文，判断下列句子是否与短文内容相符，相符的写“T”，不相符的写“F”。
Water is very important to us. We use water every day. Water is everywhere around us. At home，we use water to wash clothes and the dishes，cook meals，make drinks，brush teeth，have a bath and so on. At work，people use water to put out fires(灭火)，water plants，make things in factories and so on. We can swim in the water too.
However，there isn't much fresh water(淡水) on the Earth. We must save it. If we waste too much water，one day in the future，the last drop of water will be our tear(眼泪).
