Unit 2 The Olympic Games reading课时作业

Ⅰ.单项填空

1．The rapid development of computer has in turn________ the development of technology itself.

A．increased B．advanced

C．produced D．predicted

答案　B

解析　句意为：计算机的快速发展反过来又推进了科技本身的发展。advance推进，符合句意。increase增加，增长；produce生产；predict预测。

2．It is often the case________ anything is possible for those who hang onto hope.

A．why B．what

C．as D．that

答案　D

解析　考查主语从句的引导词。句意为：通常情况下，对于那些心存希望的人来说，一切皆有可能。本句中的it为形式主语，真正的主语为后面的名词性从句，从句结构完整，不缺成分，故要用that引导。

3．They made up their mind that they________ a new house once Larry changed jobs.

A．bought B．would buy

C．have bought D．had bought

答案　B

解析　考查过去将来时。从句"一旦Larry换了工作他们就买所新房子"在主句"他们下定决心"之后。根据"主过从过"原则，主句是一般过去时，故从句用过去将来时。

4．Though he missed a chance ________his gold medal，he said he felt satisfied with the response from the crowd，coaches and his opponents in the final.

A．defending B．to defend

C．to defending D．to be defended

答案　B

解析　句意为：尽管他失去了蝉联冠军的机会，他说他对在决赛中来自观众、教练以及对手的反应感到满意。chance后常接动词不定式作定语。

5．I'll be out for some time. ________anything important happens，call me up immediately.

A．In case B．As if

C．Even though D．Now that

答案　A
