Unit 1 cultural relics using language课时作业

Ⅰ.单项填空

1．Some of you may have finished Unit One.________，you can go on to Unit Two.

　　A．If you may B．If you do

　　C．If not D．If so

答案　D　[句意：你们中有些人可能已经完成了第一单元。如果是的话，可以继续第二单元。if so如果这样的话，so代替前面表示肯定意义的句子you have finished Unit One。正确答案为D。]

2．After the glasses fell to the ground and broke，the little boy____________his grandma about that.

　　A．dare not tell B．dare not telling

　　C．dare not to tell D．didn't dare tell

答案　D　[考查dare的用法。dare用作情态动词时，无人称的变化，但有过去式，即dared，后跟动词原形，因此排除A、B、C；在选项D中，dare用作实义动词，这时其后的动词不定式可不带to。]

3．My little son ________out alone at night.

　　A．dares not go B．dares not to go

　　C．dare not to go D．doesn't da re to go

答案　D　[在A、B答案中的dare应该是实义动词，其否定式应为doesn't dare；C项中的dare为情态动词，后接动词原形，故选D项。]

4．You have nothing to ________by refusing to listen to our advice.

　　A．gain B．grasp C．seize D．earn

答案　A　[句意：不听我们的意见对你没有好处。gain获得好处、利益等，符合题意。]

5．He ________the person referred to be put into prison.

　　A． said B．demanded

　　C．agreed D．thought

答案　B　[尤其注意题干中的referred to是过去分词短语作定语修饰the person，谓语动词为(should)be，只有B项动词后面的从句用虚拟语气。]

A．declined B．lessened C．slipped D．supplied
