语法专项突破六语法专练知能闯关

Ⅰ.单项填空

1．(2012·临沂质量检测)—You didn’t wait for Elizabeth last night，did you?

—Yes，but we __________.She didn’t come at all.

A．don’t have to B．needn’t have

C．need to D．should have

解析：选B。考查情态动词。句意为：——你昨天晚上没有等到伊丽莎白，是吗？——是的，但是我们本没有必要等。她根本就没来。根据语境可知，此处表示本没有必要做某事，故用needn’t have done。即B项正确。

2．(2012·青岛市第二次统一检测)—We would appreciate it if you could stay for lunch.

—Sorry，I __________.I have another appointment.

A．won’t B．shan’t

C．can’t D．mustn’t

解析：选C。考查情态动词用法。根据下文“I have another appointment”可知，我不可能留下来吃午饭。can’t意为“不可能”，符合题意。

3．(2012·淄博模拟)You __________ read a book in the sun—it’ll do harm to your eyes.

A．couldn’t B．wouldn’t

C．needn’t D．mustn’t

解析：选D。考查情态动词用法。句意为：你不要在太阳下看书，那样对眼睛不好。couldn’t 意为“不能；无法”；wouldn’t表示不会；needn’t意为“不必”；mustn’t表示不允许。故D项正确。

4．(2012·山东省实验中学诊断)Do you know Herbie？I’m always running into him；he __________ live nearby.

A．would B．need

C．must D．should

解析：选C。考查情态动词。句意为：你认识Herbie吗？我总是遇见他，他肯定住在附近。表示比较肯定的推测用must。故选C。

5．(2012·泰安一轮质量检测)When he was there，he _________ go to that coffee shop at the corner after work every day.

A．must B．should

C．would D．might

解析：选C。考查情态动词。句意为：当他还在那儿时，每天下班后都会去街角的咖啡店。根据语境可知此处应用过去将来时，即would正确。

6．(2012·德州模拟)A hiking trip really sounds very exciting.However，it __________ be very tiring and even dangerous sometimes.

A．will B．should

C．must D．can

解析：选D。考查情态动词。句意为：远足旅游听起来真是让人兴奋不已。然而，它有时也非常累人甚至很危险。can表示一时的可能性。故D项正确。

7．(2012·济宁模拟)—Tom is very upset.I wish I _________ him the disappointing news.

—I told you not to，but you wouldn’t listen.

A．didn’t tell B．hadn’t told

C．haven’t told D．wouldn’t tell

解析：选B。当wish后面的宾语从句中，表示与过去的事实相反的假设时，谓语动词要用“had done”的形式。而本题正是表示与过去的事实相反的假设，故选B。

8．(2012·滨州模拟)—Jane didn’t show up last night，did she?

—No.She __________.We had changed our plan.

A．shouldn’t have come B．didn’t need to come

C．needn’t have come D．needn’t come

解析：选B。shouldn’t have done意为“(过去)本不该做某事(实际做了)”needn’t have done意为“(过去)本不必做某事(实际做了)”。根据语境知我们早改变了计划，因此她没必要来的。故B项正确。needn’t do中need是情态动词，时态与语境不符。

9．(2012·山东临沂期中)—I ________ thank you enough for what you have done for me.

—You’re welcome.

A．may not B．will not

C．must not D．cannot

解析：选D。句意：——你为我所做的一切我感激不尽。——别客气。cannot...enough/cannot...too...再……也不为过，固定搭配。

10．(2012·浙江宁波十校联考)What a pity！If I had caught that flight，I________over the Pacific Ocean now.

A．would fly B．would have flown

C．would be flying D．were flying

解析：选C。句意：真遗憾。如果我赶上了那趟航班，我现在正在太平洋上空飞行呢。根据句意可知该句用虚拟语气；根据主句中的now可知，主句用与现在事实相反的虚拟语气；根据句意可知，是对“此刻”情况的推测，所以C项正确。
