Unit 4 Making the news using language课时作业

第一节　单项填空(共15小题；每小题1分，满分15分)

请阅读下面各题，从题中所给的A、B、C、D四个选项中，选出最佳选项。

1.-Do you know __________they got to know each other?

-It was last year __________they both taught Chinese in the USA.

A．when it was that；that

B．when it was that；when

C．when was it that；when

D．when was it that；that

答案　B

解析　句意为：--你知道他们什么时候认识的吗？--去年他们在美国教中文时。第一空是强调句型，在句中作know的宾语，根据宾语从句的特点可知，应用陈述语序，因此排除C、D两项；第二空引导定语从句，从句中不缺主语或者宾语，应考虑填副词，故用when引导。

2．My uncle's house in the downtown area is much smaller than ours，but it is twice __________expensive.

A．as B．so

C．too D．very

答案　A

解析　考查倍数的表示方法。该题是"倍数＋as＋adj./adv.＋as"这一结构，省略了从句中与主句相同的部分，故选A项。

3．_________，perhaps we'll win the next game.

A．Go ahead B．Don't mention it

C．Cheer up D．Well done

答案　C

解析　Go ahead前进；Don't mention it不要再提了；Cheer up振作起来；Well done干得不错。句意为：振作起来，我们将赢得下一场比赛。根据句意可知选C。

4．Doctors are doing research to find out what happens physically when people_______smoking.

A．quit B．decline

C．prevent D．reserve

答案　A
