现在英语语法考题有个趋势就是不单是考查语言规则，更不是考查语言规则的死记硬背，而是注重考查语言知识的具体运用，即将语言知识置于一定的语境中，要求考生在实际语言环境中选择一个最佳的、最得体的、当然也是最地道的选项。面对这类考题，同学们首先就要认真读懂题干，仔细分析题干所提供的语境，注意挖掘其中的隐藏信息，从而找到解题的突破口。下面请看几个实例分析：
◇Thank you very much indeed. If it had not been for your advice I really _________ what I should have done.
A. don’t know B. didn’t know C. hadn’t known D. wouldn’t have known
【分析】此题的空格前后均用了虚拟语气，空格处是否应该要用虚拟语气呢？有的同学会说要用虚拟语气，也有的同学可能会说不用虚拟语气。到底用还是不用，实话告诉你吧，不宜用虚拟语气，这是句子上下文的语境决定的。那么这个语境是什么？怎样分析？请看本节后面有关例题。
◇How beautifully she sings! I have never heard _________ voice.
A. a better B. a best C. the better D. the best
【分析】此题的最佳答案是不是 D? 因为按语法常识，最高级前应用定冠词；或者选C？因为比较级前用定冠词（如 the better one）也是可能的；或者选A或B？告诉你吧，最佳答案为A，这也与上文的语境有关（同时还涉及省略），你想知道详细分析吗？请往后面看。
◇“I don’t like him, _________?” “No, I don’t at all.”
A. do I B. do you C. don’t I D. does she
【分析】此题是考查反意疑问句吗？最佳答案是A吗？不是，完全不是。答案选B，理由见后。
本节专门搜集中学英语中一些典型的因忽略语境而出错的试题，供同学们参考。
1. Having a trip abroad is certainly good for the old couple, but it remains _________ whether they will enjoy it.
A. to see B. to be seen C. seeing D. seen
【分析】此题容易误选A，简单地认为动词 remain 后接动词要用不定式，而忽略了句子的语境，进而忽略了 to see 的语态。句中的 it 不是指示代词，而是形式主语，真正的主语是空格后的 whether they will enjoy it，也就是说此句的实际结构是 … but whether they will enjoy it remains _________. 由此可见，whether they will enjoy it 与动词 see 的关系应是被动的，而不是主动的，答案应选B。
2. “I don’t like him, _________?” “No, I don’t at all.”
A. do I B. do you C. don’t I D. does she
【分析】此题容易误选A，认为这是一个普通的反意疑问句：陈述部分主语为I，疑问部分主语也应是I；陈述部分为否定式，所以疑问部分要用肯定式。做此题的关键是要看下文的语境，下文说“No, I don’t at all.”（不，我一点也不喜欢），这表明前一句是在询问对方的看法，所以此题的最佳答案应是B，它是 do you like him? 的省略形式，全句意为“我不喜欢他，你呢(你喜欢他吗)?”
3. “
A. do you B. will you C. didn’t you D. don’t you
【分析】此题容易误选D，与上题一样，认为这是一个普通的反意疑问句。此题的下文语境“But I fed it yesterday”(但是我昨天才喂过鸟)很重要，它表明上文是在要求对方喂鸟。另外，前一句中的称呼语 Alice 也是一个重要的信息，联系此信息和下文语境，我们可断定 you feed the bird today 是一个带有主语的祈使句，所以此题的最佳答案应是B。
4. “I’ve never found a better job.” “_________.”
A. I don’t think so B. Too bad
C. Congratulations D. Don’t worry
【分析】此题容易误选B或D，主要是将上文的意思理解错了，即将其理解为“我从来没找到一份好工作”。其实，I’ve never found a better job 的实际意思是“这是我所找到的最好的一份工作”，此句可视为 I’ve never found a better job than this job (我从来没有找到比这份工作更好的工作，即这是我所找到的最好的工作)之省略，面对此话，对方最佳的回答当然应是C，即表示祝贺。请看下面一道，最佳答案是C，你明白是什么原因吗？
“What do you think of the service here?” “Oh, _________. We couldn’t have found a better place.”
A. too bad B. sorry C. wonderful D. impossible
5. How beautifully she sings! I have never heard _________ voice.
A. a better B. a best C. the better D. the best
【分析】此题容易误选D，认为最高级前用定冠词才是最佳的。其实此题最佳答案为A，该句可视为是下面这句的省略形式：…I have never heard a better voice than her voice. 全句句意为“她唱得多好啊！我从未听过她这么好的声音”。请再看以下类似的实例：
He is fine, never better. 他很好，比以往任何时候都好。
I've never seen a finer bird. 我从未见过比这更美的鸟(即这是我见过的最美的鸟)。
I’ve never found a better job. 这是我找到的最好的工作。
比较以下试题，情形也大致相同：
(1) Boris has brains. In fact, I doubt whether anyone in the class has _________IQ.
A. a high B. a higher C. the higher D. the highest
答案选B，句意为“……我怀疑班上有没有哪个人比他智商更高”，即“我认为他可能是班上智商最高的”。
(2) “Are you satisfied with his answer?” “Not at all. It couldn’t have been _________.”
A. better B. worse C. more D. less
【分析】此题最佳答案为B，关键是要理解 Not at all 的意思。根据上文语境，Not at all 为 I am not satisfied at all with his answer. 之省略，即表示“我对他的回答一点也不满意”，既然如此，他的回答当然会是 couldn’t have been worse（不可能更糟）。
6. “I _________ his telephone number.” “I have his number, but I _________ to bring my phone book.”
A. forget, forget B. forgot, forgot C. forget, forgot D. forgot, forget
【分析】此题容易误选A，认为“忘记”是现在的事。仔细体会一下对话的语境：第一个人说“我忘记他的电话号码了”，这个“忘记”应该是现在的事，即现在忘记了，要不然就没有必要同对方说此话了，故第一空应填 forget；第二个人说“我有他的号码，但我忘记带电话本了”，这个“忘记”应该是过去的事，即过去忘记带电话本，所以现在电话本不在身上(注意句中的转折连词 but)，故第二空应填 forgot。请再看一例：
― Oh, I _________ where he lives.
― Don’t you carry you address book?
No, I _________ to bring it.
A. forget, forget B. forgot, forgot C. forget, forgot D. forgot, forget
答案选C，理由同上。
7. Thank you very much indeed. If it had not been for your advice I really _________ what I should have done.
A. don’t know B. didn’t know C. hadn’t known D. wouldn’t have known
【分析】此题容易误选C或D，认为此句既然为虚拟语气语境，当然应选择与虚拟语气有关的答案。此句的句意是“真的是太感谢你了。要不是因为你给我提的建议，我真不知道自己做出了什么蠢事来”，句中 if it had not been for your advice 和 what I should have done 用了虚拟语气，表示与过去事实相反的假设，但是句中的“我不知道”也要用虚拟语气吗？换句话说，“我不知道”是与事实相反的假设吗？显然不是。所以它不能用虚拟语气，应用陈述语气(I don’t know)，表明这是事实（表达自己对对方的感谢之意）。请再看几个类似的例子：
(1) “It’s a long time since we last heard from her.” “Yes, how I wish I knew how she is getting along.” “我们很久没收到她的来信了。”“是啊，我多希望知道她现在过得怎么样。”
按照英语语法，I wish 后接宾语从句时，从句谓语要用虚拟语气，所以其后的 I knew 也的确用的是虚拟语气，但是I knew 后的宾语从句用不用虚拟语气呢？不用。句中说“我多么希望知道”，说明现在并不知道，即现在“知道”并不是事实，只是一种想法，故用了虚拟语气；但是“她现在过得怎么样呢？”则是她现在的实际情况，是事实，故用陈述语气。
(2) I wish I knew what is happening. 但愿我知道现在正在发生什么事。
此句I knew 用虚拟语气，说明现在想知道，但实际并不知道；其后的 what is happening 没用虚拟语气，是因说话者想知道现在实实在在发生的情况，即想知道“现在正在发生什么情况”这一事实。比较下例：
(3) I wish I knew what was happening. 要是我当时知道正在发生什么事就好了。
此句用 what was happening 也非虚拟语气，而是陈述语气的过去进行时态，指过去正在发生的事情。
8. I had no idea _________ is better, so I took _________ of them.
A. what, both B. what, none C. which, both C. which, none
【分析】此题的关键语境是句中的 better 一词，better 用的是比较级，说明比较的对象应是两者，由此可知第二空应填both 为好；由于谈的是两者，说明选择范围很明确，所以第一空应填 which。即答案应选C。
9. “Would you like a cup of coffee or a glass of beer?” “_________ will do, but milk is _________ popular with me.”
A. Neither, not B. Both, more C. Either, the most D. All, the most
【分析】此题容易误选B，认为前文提到 coffee 和 beer 为两者，故其后应选 both 和 more 与之对应(more 为比较级，指两者比较)。但是，这样想的同学忽略了下文的语境已发生变化――后者谈的既不是 coffee 也不是 beer，而是 milk，即第二空涉及的不是两者，而是三者，故第二空应填 the most，即此题最佳答案为C。
10. “It looks as if he were drunk.” “So it does. _________.”
A. He’d better give up drinking B. He shouldn’t have drunk so much
C. Health is more important than drink D. I wonder why he is always doing so
【分析】此题最佳答案为D，但A、B、C均有可能误选，主要是受题中 drunk 一词的影响。做此题的关键是要抓住It looks as if he were drunk 中的关键词were，因为它表明此句的谓语为虚拟语气，也就是说，“他喝醉了”不是事实，只是他的言行好像是喝醉了，所以此题的最佳答案是D。另外注意，句中的 so it does 表示强调，意为“他看上去的确像是喝醉了”。类似用法：“The building looks beautiful.” “Yes, so it does.” “这房子看上去很美。”“是的，看上去的确很美。”此句中的 so it does 也表强调。
11. I had hoped to see her off at the station, but I _________ too busy.
A. was B. had been C. would be D. would have been
【分析】此题容易误选B或D，认为前句用了had hoped，所以此句谓语要用B或D与之呼应。正确答案为A：前一句谓语用had hoped，表示的是过去未曾实现的想法或打算，可以译为“本想”，而后一句说“我太忙”，这是陈述过去的一个事实，所以要用一般过去时。请看类例(答案均为A)：
(1) We had hoped to catch the 10:20 train, but _________ it was gone.
A. found B. had found C. would find D. would have found
(2) We had hoped that you would be able to visit us, but you _________.
A. didn't B. hadn't C. would not D. would not been
(3) We had wanted to come to see him, but we _________ no time.
A. had B. had had C. would have D. would have had
(4) I had expected to come over to see you last night, but someone _________ and I couldn't get away.
A. called B. had called C. would call D. would have called
12. “_________ is her husband?” “The man standing by the window, wearing a blue jacket.”
A. Where B. How C. Which D. What
【分析】此题容易误选A，受答句中 by the window 的影响。最佳答案选C，主要由下文的语境而定：“哪个(which)是她的丈夫?”“站在窗子边，穿蓝色夹克衣的那个(人是她的丈夫)。”事实上只要改变上文，其他几个选项是完全可能的：
(1) “_________ is her husband?” “In Room 305, which has a red door.”
A. Where B. How C. Which D. What
答案选A，句意为：“她丈夫在哪？”“在305房间，房间门是红色的。”
(2) “_________ is her husband today?” “Much better now. Thank you for coming to see him.”
A. Where B. How C. Which D. What
答案选B，句意为：“她丈夫今天怎么样？”“好多了，谢谢你来看他。”
(3) “_________ is her husband?” “A teacher, an excellent teacher respected by students.”
A. Where B. How C. Which D. What
答案选D，句意为：“她丈夫是干什么的？”“当老师的，是一位备受学生尊重的好老师。”
13. Dear me! Just _________ at the time! I _________ no idea it was so late.
A. look, have B. looking, had C. look, had D. looking, have
【分析】此题容易误选D，认为第一空用现在分词表伴随，第二空填 have 的一般现在时，以保持与前面时态的一致性。其实，此题应选C，第一空应填 look, 因为这是祈使句的谓语；第二空应填 had，因为前一句说“看看时间吧”，这一看当然知道了现在很迟的情形，“不知道这么迟了”显然应是“过去”的事，故应用一般过去时态，许多同学由于忽略这一隐含的语境而误选。正确答案选C。
14. “The light in the office is still on.” “Oh, I forgot _________.”
A. turning it off B. turn it off C. to turn it off D. having turned if off
动词 forget 后接动词时，可用不定式，也可用动名词，但含义不同：接不定式，表示动作尚未发生；接动名词，表示动作已发生。此题从上文语境看，“办公室的灯还是亮着的”，说明“关灯”的动作尚未发生，故应选C答案。有的同学由于没有真正弄清上文的语境而误选了A或D。
15. “Please don’t make a noise.” “_________. I’ll be as quiet as a mouse.”
A. Yes, I do B. No, I don’t C. Yes, I will D. No, I won’t
有的同学由于受前一句don’t 的影响，认为下文的答句应选A或B，这些同学主要是忽略了上文的真实语境：上文是一个祈使句，而祈使句表示的时间应是“将来”，这从空格后的 I’ll be … 这个将来时态也可看出。另外，从 I’ll be as quiet as a mouse 这一语境来看，此题的最佳答案应选D而不选C。No, I won’t. 为 No, I won’t make any noise 之省略。请再看几例（答案均选B）：
(1) “Don’t forget to come to my birthday party tomorrow.” “_________.”
A. I don’t B. I won’t C. I can’t D. I haven’t
(2) “Write to me when you get there.” “_________.”
A. I must B. I will C. I can D. I should
(3) “Never tell him about it.” “ _________.”
A. Yes, I don’t B. No, I won’t C. Yes, I won’t D. No, I haven’t
顺便说一句，由于祈使句表示的时间属“将来”，所以当祈使句后接一个反意疑问句时，可用 will you 之类的：
Be quiet, will you? 请安静，好吗？
Please come over, will [won’t] you? 请过来，好吗？
Don’t forget to phone me, will you? 别忘了给我打电话，好吗？
肯定的祈使句后，可用 will you 或 won’t you 等，但否定的祈使句后，要用 will you，而不能用 won’t you。
16. “How long has this bookshop been in business?” “_________ 1982.”
A. After B. In C. From D. Since
【分析】此题若仅从答句来看，似乎四个答案均可以。但根据上文语境两个关键性的信息how long 和 has been，可知答句应是一个表示一段时间的短语，且应可以连用现在完成时态。所以答案应选D。比较以下各题 (答案均为D)：
(1) “When did the bookstore start?” “_________ 1982.”
A. With B. Since C. From D. In
(2) “How long did you work in the bookstore?” “_________1982 to 1988.”
A. After B. In C. Since D. From
17. “Your phone number again? I _________ quite catch it.” “It’s
A. didn’t B. couldn’t C. don’t D. can’t
【分析】此题容易误选C，认为此处要用一般现在时态，表示现在“没听清对方的话”。其实，答案应选A，根据上文的语境“请把你的电话号码再说一遍好吗？”，可知“没听清对方的电话号码”应是在说此话以前，故应用一般过去时态。请看类例：
(1) “Mr Smith isn’t coming tonight.” “ But he _________.”
A. promises B. promised C. will promise D. had promised
答案选B，“他答应(要来)”应发生在过去。
(2) “Hey, look where you are going!” “Oh, I’m terribly sorry. _________.”
A. I’m not noticing B. I wasn’t noticing
C. I haven’t noticed D. I don’t notice
答案选B，“我没注意”是对方提醒之前的事，现经对方一提醒，当然注意到了。
比较(www.yygrammar.com)：
“What’s his name?” “I _________.”
A. forget B. forgot C. had forgotten D. am forgetting
【分析】此题应选A，从语境看，“忘记”的时间应是现在，即指现在不记得了。
18. “You haven’t been to
A. Yes, I have B. Yes, I haven’t C. No, I have D. No, I haven’t
【分析】此题不宜选B或C，因为这两个答案本身就有问题，即 Yes 后用了否定式，而No 后用了肯定式。至于A和D，则有许多同学拿不准该选哪一个，因为单独看问句和A、D两个选项，两个选项都没错。此题的关键是要看下文的语境，即 How I wish to go there! (我多么希望能去那儿啊)，这说明说此话的人还没去那儿（即没去过北京），所以答案应选D。同学们想想看，假若此题按下题这样改动一下，情形又如何呢？
“You haven’t been to
A. Yes, I have B. Yes, I haven’t C. No, I have D. No, I haven’t
【分析】此题的最佳答案就不再是D了，而应是A。因为题中说 and how I wish to go there again，(注意句中 again 一词)，这说明说话人曾去过那儿（即去过北京），所以要选A。
19. Professor White has written some short stories, but he is _________ known for his plays.
A. the best B. more C. better D. the most
【分析】此题首先不宜选B或D，因为 well known 的比较级和最高级通常是 better known和best known，有时也可以是 more well known 和 most well known，但通常不能是 more known 和 most known。至于是选A还是C？这就要看语境。由于A和C的区别是比较级和最高级的区别，所以区分这两个答案的关键就是要分清句中涉及的是两者比较，还是三者或三者以上的比较。细读全句，我们发现句中涉及的只有 stories 和 plays 这两者，所以应选C为最佳。
20. Mr Smith _________ a book about
A. has written B. wrote C. had written D. was writing
【分析】此题应选D，这是由 but I don’t know whether he has finished it 这一句话的语境决定的，全句意为“
21. Robert is said _________ abroad, but I don’t know what country he studied in.
A. to have studied B. to study C. to be studying D. to have been studying
【分析】此题4个选项都容易误选，其实最佳答案应是A，主要是因为下文but I don’t know what country he studied in 这一语境，注意此句中的过去时谓语动词 studied，这说明“他”在国外学习是过去的事，进而可以推知填空处应用不定式的完成式。请看类例：
(1) He was _________ the new ambassador, but he fell ill.
A. to be B. being C. to have been D. having been
最佳答案选C，注意下文的 but he fell ill，指的是过去。
(2) I wish I’d been there ― I would like _________ her face when his husband came in.
A. to see B. to have seen C. seeing D. having seen
最佳答案选B，注意上文的 I wish I’d been there，涉及的是过去的情况。
22. “Why haven’t you bought any butter?” “I _________ to but I forgot about it.”
A. liked B. wished C. meant D. expected
【分析】此题似乎4个选项都对，但根据上下文的语境，只有C为最佳，I meant to 为 I meant to buy some butter 之省略。甲问乙为什么没买黄油，乙回答说“本来打算买的，但忘记了”。在所提供的4个选项中，各个动词均可后接不定式，但要表示“本来打算做某事而没有做”这一意思时，以用 meant to do sth 为最佳。
23. I read about it in some book or other, does it matter _________ it was?
A. where B. what C. how D. which
【分析】此题答案选D，主要与上文的some book or other (某一本书)这一语境有关，全句句意为：“我在某一本书上读到过它，是哪一本书这很重要吗？”请看类例：
(1) “Who told you?” “Oh, somebody or other, I’ve forgotten _________.”
A. what B. when C. which D. who
答案选D。句意为：“谁告诉你的？”“噢，有个人，我忘记是哪一个了。”
(2) Some of the students were late for the meeting, but I can’t remember _________.
A. what B. when C. which D. whom
最佳答案为C。句意为“有些学生开会迟到了，但我不记得是哪些学生了”。
24. “Is John coming by train?” “He should, but he _________ not. He likes driving his car.”
A. must B. can C. need D. may
【分析】此题最佳答案为D，这是由上下文的语境决定的。句中的 He should 为 He should come by train 之省略，但紧接着跟了一个转折连词 but，说明语意有变化，再结合下文的 He likes driving his car，便可决定此题选D，may not 意为“可能不(会坐火车来)”。
25. “I heard they went skiing in the mountains last winter.” “It _________ true because there was little snow there.”
A. may not be B. won’t be C. couldn’t be D. mustn’t be
【分析】此题最佳答案为C，主要由下文的 because there was little snow there 这一语境所决定，既然“没下什么雪”，那么“滑雪”就应是“不可能”，所以选 couldn’t be，即选C。
26. You can get there by plane or by boat, but in _________ case it’s very expensive.
A. which B. this C. any D. either
【分析】此题应选D，其余三项均有可能误选。首先不能选A，因为句中有并列连词 but，况且前面一句有 by plane 和 by boat 两种选择，这与 which 所表示的确定含义也不相符；B也不能选择，因为 this 也是表示“确定”含义的，它与前面的 by plane or by boat 这种不确定性也不相符；选项C也不行，因为 any 是表示三者或三者以上的情形的，而 by plane or by boat 只有两种选择。答案选D，either 表示“两者中任意之一”。
27．These trousers are wet ― I’ll change into my _________.
A. another B. trousers C. others D. other
【分析】此题容易误选A或B。有的同学认为，既然这条裤子湿了，那么我就换另外一条，所以用 another，但是这些同学忽略了 another 后通常接单数名词，而 trousers 是个复数名词，所以不行；选 trousers 也不行，同学们只要把它填入空格处翻译一下就知道，填 trousers 句子意思不通。正确答案应选C，others 等于 other trousers，其中的 other 是与前面的 these 相对照的，即“这条”裤子湿了，我就换“其他”的裤子。
28. Her lecture was hard to follow because she kept jumping from one subject to _________.
A. other B. the other C. the others D. another
【分析】此题容易死套搭配 one … the other…而误选B，其实最佳答案为D。使用one…the other … 时，我们通常是针对两者而言的，即指“两者中的一个……，另一个……”；如果所谈论的情况不是针对两者而言的，而是针对多者而言的，那么我们就不宜在 one 后使用 the other，而考虑用 another。又如(答案均选D，即选 another)：
(1) Those cakes are wonderful. Could I have _________ one?
A. other B. the other C. the others D. another
(2) I have many such novels. I’ll bring _________ tomorrow.
A. other B. the other C. the others D. another
(3) Saying is one thing and doing is _________.
A. other B. the other C. the others D. another
比较以下各例：
(1) Shut _________ eye, Jim.
A. another B. some other C. other D. the other
答案选D，因为人的眼睛只有两只，故用 one…the other 结构。
(2) It’s sometimes hard to tell one twin from _________.
A. another B. some other C. other D. the other
答案选D，twin 意为“孪生子之一”、“双胞胎之一”，即指两者之一，故用 one…the other 这一结构。
29. You are _________ careful than your brother. You two can’t do the work that needs care and skill.
A. not more B. no more C. not less D. no less
选对此题，至少要弄清两点：一是下文的语境，二是 not more than, no more than 等结构的含义。下文说 You two can’t do the work that needs care and skill(你们两个都不适合做这需要细心和技巧的工作)，这就表明这两个人都不是很仔细的人。再看选项中所涉及的几个结构的意思：
not more … than = 不如……(www.yygrammar.com)
no more … than = 和……一样不(否定两者)
not less … than = 不如……不（即指不如 less 后形容词的反面）
no less … than = 和……一样(肯定两者)
比较以下各句的意思：
You are more careful than he is. 你比他仔细。
You are not more careful than he is. 你不如他仔细。
You are no more careful than he is. 你和他一样不仔细。
You are less careful than he is. 你不如他仔细（你比他粗心）。
You are not less careful than he is. 你比他仔细（你不如他粗心）。
You are no less careful than he is. 你和他一样仔细。
综合以上分析，上面一题的最佳答案应是B。
30. I want very much to buy a colour TV set, but I can’t afford _________.
A. it B. one C. this D. that
答案选B，但容易误选A。it 和 one 的区别可简单地概括为：it = the + 名词，one = a + 名词。如：
I haven’t any dictionaries, and I want to borrow one. 我没有词典，我想借一本。(one = a dictionary)
I have two dictionaries, and I can lend one to you. 我有两本词典，我可以借一本给你。(one = a dictionary)
I have a dictionary, and I can lend it to you. 我有一本词典，我可以把它借给你。(it = the dictionary)
根据上面一题的语境，句子后半截显然应该是 … but I can’t afford a colour TV set，而不是 but I can’t afford the colour TV set，所以答案选B。
31. I have no idea _________ is better, so I took both of them.
A. what B. which C. how D. why
【分析】此题应选 B。C或D 不能选，是因为它们是副词，不能用作主语。A和 B 均为代词，均可用作主语，其区别是：which 通常指有明确范围的选择，而 what 则通常指没有明确范围的选择，那么到底本句所体现的选择范围是明确还是不明确呢？请注意句中的隐藏信息 better 和 both of them，这说明选择范围是明确的(即只有两者)，故选 B 为佳。
32．“Mary looks hot and dry” “So _________ you if you had a high fever.”
A. do B. are C. will D. would
【分析】此题容易误选A或C。选A者，认为前后两句的动词性质应一致；选C者，认为其后带有if 条件状语从句，从语气上看，主句应用将来时态。以上两种分析都有一定道理，但是不完全对。用“so+助动词+主语”表示“……也一样”时，在多数情况下，其中的助动词会与前一句的动词性质一致。如：
He is ill, and so am
He can do it and so can
He likes it and so do
但是，有时也不一定如此。如：
If you go, so shall
When animals and plants disappear, so will man. 当动植物消失的时候，人类也会随之消失。
至于为什么不能选C，那是因为其后的 if 条件状语从句的谓语用的是虚拟语气（许多同学会忽略此信息），所以主句要用 would 而不用 will，即答案应选D。
33. _________ big fish! Where did you get them?
A. What B. What a C. How D. How a
假若单独就 _________ big fish! 这一句而言，选A 或B都是可以的，但因为 fish 用作可数名词时，它的单数与复数同形。但问题是，下文中有个 them，这说明前面的 fish 是复数而不是单数，所以此题的正确答案应是A。
34. Once your business becomes international, _________ constantly will be part of your life.
A. you fly B. your flight C. flight D. flying
【分析】此题最佳答案为D，其余几项均有可能误选。最容易为同学们忽略的隐含信息是句中的副词 constantly，由于它的出现，这就注定了不能选B或C，因为B、C均为名词，不能受副词 constantly 的修饰。A和D均是可能的，因为其中有动词 fly。但若选A，you fly 是一个主谓结构，与其后的谓语 will be 相冲突，所以只能选D ―― flying 是动名词，在此用作主语(www.yygrammar.com)。
35. There are four bedrooms, _________ with its own bathroom.
A. all B. each C. every D. either
【分析】此题容易误选A，认为前面有 four，属多者，故用 all。其实，正确答案应为B，注意空格后的隐藏信息 its，它表示空格处应填一个单数代词 (注意：不能选C，因为 every 不能单独作主语)。
36. “Would you like coffee or tea?” “We’d like three black _________.”
A. coffee B. coffees C. cups of coffee D. cup of coffees
【分析】此题容易误选C，因为“三杯茶”、“三杯咖啡”等的通常表示法便是 three cups of tea, three cups of coffee。但是，选C的同学忽略了一个重要信息，即空格前的 black。在英美国家，有的人喜欢在咖啡里添加牛奶，并且把加了牛奶的咖啡叫做 white coffee，而把没有加牛奶的咖啡叫做 black coffee。由此可见，上题中的 black 应是修饰 coffee 的，而不是修饰 cup的。另外有个问题，即有的同学认为 coffee 是物质名词，不可数，不能用 three coffees 这样的表达，其实，coffee既可用作不可数名词，表示“咖啡”这种物质，也可用作可数名词，表示“一杯咖啡”，即在口语中 three coffees 就等于 three cups of coffee。类似地，“三杯茶”既可说成 three cups of tea，也可说成 three teas；“三杯啤酒”既可说成 three glasses of beer，也可说成 three beers。请再做下面一题：
“Would you like coffee or tea?” “We’d like three black _________.”
A. tea B. teas C. cups of tea D. cup of teas
答案选B，理由同上题。注：black tea 指“红茶”(英语习惯上不说 red tea)。
37. He has changed a lot. He _________ not what he _________.
A. is, is B. was, was C. is, was D. was, is
答案选C，上文说“他”变化很大，即“他”现在不是过去的那个样子了，故第一空填is，第二空填 was（其实第二空也可用 used to be）。请看类例：
“Look! That may be the same tree that we happened to see two hours ago.” “My God. We _________ back where we _________.
A. are, are B. were, were C. are, were D. were, are
答案选C，We are back where we were 的意思是“我们现在又回到刚才来过的地方”。
38. “Do you think he is lazy?” “I _________ once, but I don’t now.”
A. may have thought B. can have thought
C. may think D. might think
答案选A。从答话人的语境可知，空格处的意思“曾经这样想过”，即对过去情况作推测，故应用“情态动词+动词完成式”，又因为 can 表推测不用于肯定句，故选A。请看类例：
Their answers are exactly the same ― one of them _________ from the other.
A. must copy B. must have copied C. should copy D. should have copied
答案选B，既然两人的答案完全一样，说明“抄袭”已经发生，故用“情态动词+动词完成式”，根据句意，应选B而不能选D。
