一、选择题

1.B

解析:B

【解析】

【分析】

【详解】

句意:——杨小姐,我能从图书馆借这些书吗?——对不起,你不能。这些书仅供英语俱

乐部的会员借阅。

考查情态动词的用法。can“能,会”,情态动词;could是can的过去式。表示请求允许(即请求别人允许自己做某事)时,既可用 can也可用could,但这里的 could 并不表示过去,而是表示现在,只是比can的语气更委婉。若表示给予允许(即自己允许别人做某事),一般只用 can/can’t。综上所述,故选B。

2.C

解析:C

【解析】

【详解】

句意:你已经完成了大部分工作,所以你明天不必这么早就开始工作。你可以9点来。

本题考查情态动词。can't不可能,mustn’t禁止,needn’t不必,couldn’t可能不。根据You

have finished most of the work可知,你已经完成了大部分工作,因此明天不必这么早就开始工作,因此用needn’t,故选C。

3.A

解析:A

【解析】

【详解】

句意:既然你很累,今天就不必完成这项工作了。

A. needn’t不必;B. may not 可能不;C. mustn’t禁止;D. can’t不能。根据上文Since you

are very tired,可知,情态动词needn’t表示不需要,后面直接加动词原形。根据题意,故选A。

4.A

解析:A

【解析】

【详解】

句意:——我驾照考试又失败了。——别担心。就像天气一样,生活也不可能一直是美丽的。

考查情态动词。can't不可能;needn't不必;shouldn't不应该;mustn't一定不能。根据句意,应是不可能一直美丽。故选A。

5.A

解析:A

【解析】

【详解】

句意:你不必担心你的功课。下次小心点,你会取得好成绩的。

考查动词need用法辨析。need用作情态动词时常和不带to的不定式一起作谓语,否定式是将not置于其后,并有其否定的缩写形式needn't,在疑问和否定句中不加助动词;可知BCD三项表达错误。用作行为动词时,need是一个普通的及物动词,用在肯定、否定和疑问句中均可,接不定式时要带to。本句need用作及物动词,根据句意结构,故选A。

6.B

解析:B

【解析】

【详解】

句意:——难道弗莱克不喜欢待在家里照顾他的小妹妹吗?——是的,但是他不得不这么做因为他的父母都去工作了。

考查一般疑问句。has to不得不;doesn’t have to不必。根据后面的both of his parents work可知,弗兰克不得不在家照顾妹妹。而且but表示转折,跟前面表述的是相反的,问句是一个否定式的一般疑问句,回答“No+否定句”,no翻译成“是的”。故选B。

7.B

解析:B

【解析】

【详解】

句意:你应该因为上学迟到向老师道歉。

本题考查动词短语。apology道歉,是名词;apologize道歉,是动词;about关于,for为了,on在……上面。apologize to sb for sth“因为某事向某人道歉”,位于情态动词should后,用动词原形,故选B。

8.B

解析:B

【解析】

【详解】

句意:他可能喜欢咖啡。我看见他有时喝一杯。A. must必须;B. may可能;C. can’t不能;D. mustn’t禁止。根据下文I see him drink a cup at times.可知上文是可能喝咖啡。根据题意,故选B。

9.D

解析:D

【解析】

【分析】

【详解】

句意:——看!史密斯太太正站在教学楼的前面。——不可能是他。她去埃及度假了。

考查情态动词表示推测。must be一定是;mustn’t be禁止是;can be可能是; can’t be不可能是。根据She has gone to Egypt for her holiday.可知她去了埃及,不可能站在教学楼前,故选D。
