Unit 5 theme parks Grammar课时作业

Ⅰ.单项填空

1．When we saw the road ________ with snow，we decided to spend the holiday at home.

A．block B．to block

C．blocking D．blocked

答案　D

解析　考查非谓语动词作宾语补足语的用法。句意为：发现路面被雪封住，我们决定在家度假。宾语补足语block与宾语road为被动关系，故选D项。

2．Fifteen minutes ________all that I can spare to talk over this matter with you.

A．is B．are

C．were D．be

答案　A

解析　此处的"Fifteen minutes"作主语，表示的是整体概念，谓语动词用单数形式。

3．Not only I but also my daughter ________fond of Liu Qian's magic tricks.

A．are B．am

C．is D．were

答案　C

解析　not only...but also...连接两个主语时，谓语动词与靠近它的主语一致。my daughter是第三人称单数，故用is。

4．All the employees except the manager ________ to work online at home.

C．is encouraged D．are encouraged

答案　D

解析　encourage与employees是动宾关系，要用被动语态。all the employees作主语，谓语动词要用复数形式。

5．Listening attentively in class and reviewing in time ________a sure way to improve your learning，and this is especially true ________ it comes to standard tests.

A．is；when B．are；when

C．is；while D．are；as

答案　A

解析　考查主谓一致和固定句式。并列非谓语动词充当主语指同一件事情时，谓语动词用单数形式；when it comes to...是常用句式，表示"每当说到/谈到......，就会......"。
