助动词用法练习答案

助动词

1. 按要求改写句子。

I have been to Beijin. (改为一般疑问句) ______ you ______ to Beijin? 参考答案:Have; been

原句是现在完成时,现在完成时的一般疑问句是把助动词have前,其他不变,故该题正确答案为Have; been

2. 按要求改写句子。

He designs clothes. (改为一般疑问句) ______ he ______ clothes? 参考答案:Does; design

原句是一般现在时,并且谓语是用的第三人称单数,因此需要把助动词does提前,后面用动词原形,故该题正确答案为Does; design

3. 按要求改写句子。

There were some flowers on the teachers’ desk. (改为一般疑问句)

______ ______ ______ flowers on the teachers’ desk? 参考答案:Were there any

原句是一般过去时,要把were提前,some在疑问句中变成any故该题正确答案为Were there any

4. 按要求改写句子。

There were some apples on the tree. (改为否定句) There ______ ______ ______ apples on the tree. 参考答案:were not any

原句是一般过去时,变否定句时在were后面加notsome在否定句中变成any,故该题正确答案为were not any

6. 按要求改写句子。

I think he is very old. (改为否定句)


I ______ think he ______ very old. 参考答案:don’t; is

I think后接宾语从句变否定时,应将否定形式转移成动词think的否定形式,因此应用助动词do的否定形式don’t,故该题正确答案为don’t; is。

7. 按要求改写句子。

They had lunch. (改为否定句) They ______ ______ lunch. 参考答案:didn’t have

原句是一般过去时,助动词是did,后面跟动词原形,故该题正确答案为didn’t have。

8. If it is fine tomorrow, we ______ a football match. A. have B. will have C. has D. shall ha 参考答案:B

if用“主将从现”,主句用一般将来时,用助动词will,后面加动词原形,故正确答案为B

9. 选择适当的单词填空。

______ you like swimming? (Do/Does) 参考答案:Do

you是第二人称,一般现在时里面用助动词,故该空应填Do 10. ______ you ______ a good time on your vacation? A. Did; have B. Did; had C. Were; have D. Were; had 参考答案:A

一般过去时的一般疑问句提前助动词did,后面用动词原形,故正
