4.The fire spread through the hotel very quickly ，but everyone ______ get out.
(NMET)
A. could B. would C. was able to D. had to
析：根据题干提供的情景B、D皆应排除。在A、C两选项中，因为根据情景要选一个“经过努力能够”这样意思的词，故定答案为C。
5. I told Sally how to get here, but perhaps I ______ for her.
A. had to write it out B. must have written it out
C. should have written it out D. ought to write it out
析：A项意“(当时)不得不写出来”，不合题意；D项意“(现在)应写出来”也不合题意；B项意“(当时)肯定已写出来”明显不对。只有表“当初应该写出来”意的C项才合上下文。
6.That young man has made so much noise that he _______ not have been allowed to attend the concert. (上海高考题)
A. could B. must C. would D. should
析：若选A。意“不可能已被允许…”与情景不合，应排除；B项不可选；C项意“当时将不会被允许…”也与情况相悖。只有D “should not have been allowed…”表示“当初不该让他…”才合题意。
7.－Can I help you, sir? －Yes, I bought this radio here yesterday, but it______.(NMET)
A. didn’t work B. couldn’t work
C. can’t work D. doesn’t work
析：若选A。意“昨天不响（今天响了）”，不合题目情景；若选B。其意是“当时不能工作（现在能工作了）”，显然不合题；若选C。意为“这台收音机根本不能工作（是废品）”这未免显得武断；只有D表“这台机子不响（有毛病）”意才能合理地表达来找商店服务员的原因。
主谓一致（Agreement）
1.“Either A or B＋谓语”结构，谓语取决于Ｂ。
例：Either the students or their teacher dislikes basketball, otherwise they would take part in the basketball match.
但在一般疑问句中，谓语取决于Ａ。
例如：Do either the students or their teacher dislike basketball?
Is either he or you going there?
这种谓语取决于与其最近的主语现象叫做“就近原则”。
2．“Neither A nor B＋谓语”结构，谓语多取决于Ｂ。但现代英语也出现复数谓语，理由是neither A nor B是两部分之和，为复数概念，故其后可用复数谓语。
例如：Neither she nor I was(或were)fortunate enough to gain extra points. 她和我都不幸未能获得附加分。Neither you nor he does(或do)well in maths.
3．Neither of…接单、复谓(通常视为单数，但在口语中，从意义上亦可视为复数)
None of…接单、复谓
例：Neither of them is(或are)right.
None of you is(或are)fit for the job.
4. as well as（以及）
(together)with(以及)
“A+ along with(以及) +B+谓语”结构，谓语取决于A。
but(除去)
rather than
as well as
例：The trainer along with/(together) with two gymnasts is in the gym. 教练和两个体操运动员在体操房里。
All but Li Dong have passed the test. 除了李东所有人都通过了考试。
Nobody but Li Dong and Wang Hong has passed the test.
除了李东和王宏没有什么人通过那场考试。
5. 表示钱数、时间、长度、数学等概念名词其后通常用单数谓语。
例：200 yuan / 500 dollars / 20 minutes is not enough for us. 10 and 5 makes/ is 15. 10加5等于15.
10 minus 5 makes/ is 5. 10减5等于5.
（以上两数词例，现代英语认为make, are也对。）
20 kilometers is too much for them. 20公里是他们吃不消的。
6. There be 结构中be的形式取决于靠近be的名词，若是单数名词，则be为is/was;
若是复数名词，则be为are/were（即第１条中的“就近原则”）。
例如：There is a desk, two chairs and three sofas in the room.
There are three sofas, two chairs and a desk in the room.
7. a group of…，a team of…后跟复谓、单谓皆可，跟复谓的理由是不止一个人，跟单谓的理由是将许多人视为“一组”、“一队”这样的一个单位体。
例如：A group/team of students are /is cleaning the street.
8. 像school, class, family, team, group government等这类群体名词，其后谓语可能是单数形式，也可能是复数形式。通常视其为一个整体单位时，用单数谓语；视其为群体成员时，则用复数谓语。
例如：The class are having a meeting. 这个班学生在开会。
The class is not very big. 这个班不是大班。
The family enjoy singing and dancing. 这家人喜欢唱歌跳舞。The family has only three persons.这家只有三口人。
9. 像police, clothes, trousers这类复数概念名词，其后总是跟复数谓语。the wounded （伤员）后总是跟复数谓语。
10. 像clothing, news, information, advice这类不可数名词后应跟单数谓语，但它们前面有可数性短语修饰时，也可跟复数谓语。
例如：The clothing is very nice. The news is interesting.
Five articles of clothing are over there.
Three pieces of news were announced on TV.
11.百分数of＋复名＋复谓，百分数of＋单名／不可数名词＋单谓
例：40 percent of the students are girls.
80 percent of the work/the book has been finished.
分数后的谓语形式同百分数。
12. who/why/how/whether/if/than引导的名词从句＋单谓
例：How he got there is unknown./Why she did it remains a puzzle./It’s lucky that he is still alive.
13. A (large)number of＋复名＋复谓。
例：A number of books are over there.
A large amount of＋不可数名词＋单谓。
例：A large amount of money has been spent.
The number of＋复名＋单谓。例：The number of the students in our school is 2000.
主谓一致考点分析
1．_____either he or I to leave for America?
A. Is B. Am C. Are D. Will
析：由or, either…or, nor, neither…or, whether…or, not…but, not only…but also等连接的并列主语，其谓语动词的单复数要根据“就近原则”处理，因为空白处与he最近，故要选A。
2. No one has finished his homework, ________?
A. have they B. haven’t they C. has he D. hasn’t he
析：由No one可知空白处应选肯定式，故可排除B, D。又因为句子表述的意思是“没
有一个人完成作业”，从人数上看是很多人没完成作业，故排除C项，而选A。
3. There comes the bus, _______?
A. doesn’t there B. doesn’t it C. does it D. are there
析：这是一个倒装句，主语是bus，谓语是comes, 所以答案应选Ｂ。
4. He is a teacher but his wife is a doctor,_______?
A. isn’t she B. isn’t it C. aren’t they D. isn’t he
析：此题问句前部分含but，重点是强调his wife is a doctor, 故问句部分取决于此部分，因此，该题答案为A。
5. They don’t think money is everything, _______?
A. is it B. isn’t it C. will they D. do they
析：如果是“I/ We (don’t) think＋宾从”则反意问句主语和谓语取决于宾语从句，但此句主句的主语不是I或we，而是They, 这时反意问句部分的主语和谓语要取决于主句的主、谓语，所以此题答案应选Ｄ。
6. Each soldier and sailor ____ given a rifle when the ship landed.
A. were B. was C. are D. is
析：根据when the ship landed,可知应排除C,D.又因“each/every A and(each/every)B”结构的主语后面应跟单数谓语，所以答案为B。
7.More than one person _____ involved(卷入)in the case.
A. is B. are C. has D. have
析：要表达“被卷入”，只能在A,B之中选一个，因more than one后应跟单名，单谓，所以答案为A。
8. He is the only one of our customers who ____ this kind of article.
A. like B. likes C. are fond of D. loved
析：从时态考虑可排除D。因“the/the only…of＋复名”后的定语从句谓语应该用单数形式，所以答案应是B。但此题若将the only 去掉，则答案为A。
