必修三unit 3主謂一致

主謂一致（一）概述：主語與謂語的一致：在英語表達(dá)中，謂語動詞的形式要和主語的人稱和數(shù)保持一致。主要體現(xiàn)在動詞，助動詞 do,have 以及一般現(xiàn)在時態(tài)中的動詞形式。謂語動詞與主語保持一致的基本原則：語法一致，就近一致和意義一致。名詞或代詞做主語有人稱和單，復(fù)數(shù)之分，動詞的單數(shù)就是第三人稱單數(shù)形式，而動詞的復(fù)數(shù)形式動詞的原形。例句：1. I am seventeen, and he is sixteen.2. There is a desk in the room, but there are no chairs in it.3. John gets up at six oclock every morning.4. What is the latest news about the Olympic Games?5. The family are sitting at the breakfast table.（二）語法一致：1. 由and連接的兩個名詞或代詞做主語：（1）表示的是兩個人或兩件不同的事物，謂語動詞用復(fù)數(shù)形式。例句： My brother and I have both seen that film. Both rice and wheat are grown in this part of China. The poet and the novelist were both present at the meeting.（2）表示具有兩個身份或性質(zhì)的同一個人或一個完整的事物，謂語動詞用單數(shù)形式。特征：兩個名詞共用一個定冠詞或者形容詞性物主代詞。例句： The professor and writer is speaking at the meeting. War and peace is a constant theme in history.（戰(zhàn)爭和和平 One more knife and fork is needed.（刀叉 The stars and stripes is the national flag of U.S.A.（星條旗 Law and order has been established.（法律和秩序 Bread and butter is our daily food.（黃油面包 Fish and chips is a popular fast food.（油煎魚加土豆片（3）前面有each, every, many a, no，one more 等修飾時，謂語動詞一般用單數(shù)形式。例句： Each doctor and（each）nurse was given a new shirt. No sound and no voice is heard. Many a boy and girl has made the same mistake. Every minute and every second is precious.2. 單個的動名詞，不定式，主語從句做主語時，謂語動詞用單數(shù)形式。例句： Reading is a great pleasure in life. To live means to create. That we need more time is obvious. What is needed is food and medicine.3. 表示時間，金錢，距離，重量的復(fù)數(shù)名詞表示數(shù)量做主語時，被視為一個整體，謂語動詞用單數(shù)形式 。例句： Three thousand miles is along distance. Eight hours of sleep is enough.4. 不定代詞 anyone, anything, everyone, everything, someone, something, no ne, nothing, each the other 等做主語時，謂語動詞用單數(shù)形式。例句： Is anybody going to tell him the news ? Someone wants to see you.（三）就近原則由連詞 or, eitheror, neithernor, not onlybut also, notbut 連接的兩個名詞或代詞做主語時，以及There be句型，謂語動詞和離它最近的哪個名詞或代詞的人稱和數(shù)一致。例句：1. Either you or Jean is to be sent to New Zealand.2. Not only his family but also he likes Chaplins movies.3. Neither Tom nor the Browns enjoy their journey to Beijing owing to the bad weather.4. George or Tom is wanted.5. There is a lamp, two pens and three books on the desk.（就遠(yuǎn)原則）名詞后面帶有 with, along with, together with, besides, except, but, like, including, as well as, rather than短語共同做主語時，謂語動詞與這些短語前面的那個名詞的數(shù)一致。例句：1. All but one were here just now.2. A library with five thousand books is offered to that nation as a gift.3. An expert, together with some assistants, was sent to help in this work.4. You as well as I are wrong.（四）意義一致1. 代詞none, neither, all的不可數(shù)形式還是復(fù)數(shù)形式由它們指的內(nèi)容決定例句：（1）All hope has gone.（2）All are agreed on this point.（3）Is there any milk in the fridge? No, there is none.（4）None has returned from the meeting.2. 集合名詞group, class, family, army, enemy, team等名詞的單，復(fù)數(shù)形式根據(jù)它們強調(diào)的內(nèi)容而定。例句：（1）The class were all cheerful.（2）The team were taking over some new plays.（3）The army is going to remain in this town. 3. 限定詞短語 all of; none of; a lot of, lots of 以及分?jǐn)?shù)/百分?jǐn)?shù)+of .the rest of, plenty of , 修飾名詞構(gòu)成的名詞短語做主語時，謂語動詞的形式由 of 后面的名詞形式?jīng)Q定。例句：（1）None of the suggestions are very helpful.（2）I dont think any of us wants to work tomorrow.（3）Two-fifths of the students in the class are from Arabic-speaking countries.4. a large amount of, large amounts of 后跟不可數(shù)名詞，謂語動詞用單數(shù)。 而 a large quantity of, large quantities of 則單復(fù)數(shù)與quantity的形式一致。難點突破1. 在做主謂一致的題目時要牢記主謂一致的三個基本原則。一定要根據(jù)句子內(nèi)容抓住關(guān)鍵的主語部分。同時還要考慮句子的時態(tài)和語態(tài)。2. one of+復(fù)數(shù)名詞做定語從句的先行詞時，定語從句中的謂語動詞與復(fù)數(shù)名詞一致。the only one of+復(fù)數(shù)名詞做定語從句的先行詞時，定語從句中的謂語動詞用單數(shù)形式。例句：Jim was one of the boys who were late for class.Jim was the only one of the boys who was late for class.4. A large amount of, large amounts of, 后面跟不可數(shù)名詞，謂語均為單數(shù)。而quantities of 、a large quantity of后面可數(shù)不可數(shù)名詞，謂語看后面跟的名詞形式。【典型例題】例1 E-mail, as well as telephones,_an important part in daily communication.A. is playing B. have played C. are playing D. play分析：帶有as well as 短語的名詞做主語時，謂語動詞與這個名詞的人稱和數(shù)一致，不受as well as 短語內(nèi)容的影響。E-mail 是單數(shù)形式，故選擇 A。例2 Either John or his friends _ to blame for the bad results.A. are B. is C. was D. has been分析：eitheror.連接兩個名詞做主語時，其謂語動詞與離它最近的名詞的數(shù)和人稱一致，本題中his friends 決定了謂語動詞的形式，故選擇 A。例3 The conductor and composer_bya crowd of people.A. are greeted B. is greeted C. greets D. have been greeted分析：根據(jù)句意，主語部分的The conductor and composer 是指一個人即：樂隊指揮兼作曲家， 所以主語的內(nèi)容是單數(shù)形式，故選擇 B。例4 The trousers _you well, madam.But thecolour_me.A. fit; dont suit B. fits; doesnt suit C. fits; dontsuit D. fit;doesntsuit分析：trousers, clothes, glasses,等名詞本身就是復(fù)數(shù)形式。謂語動詞用復(fù)數(shù)形式。Colour 是單數(shù)，謂語用單數(shù)，故選擇 D。例5 The Smiths family, which _ rather a large one, _ very fond of their old house.A. were; were B. was; were C. were; was D. was; was分析：family 指“家庭”為單數(shù)，指“家庭成員”為復(fù)數(shù)形式。第一空格前的 which 指“家庭” 謂語用 was. 第二空格后的 fond of指“家庭成員喜歡他們的老房子” 謂語為 were，故選擇B。例6 He is theonly one of the students who _a winner of scholarship for three years.A. is B. are C. have been D. hasbeen分析：當(dāng)定語從句先行詞是“oneof +復(fù)數(shù)形式”時， 其后的從句謂語動詞用復(fù)數(shù)形式。而當(dāng) one之前有 the only時， 定語從句則強調(diào) the only one，謂語動詞用單數(shù)。另外，題目中的時間狀語for three years表明從句的時態(tài)為現(xiàn)在完成時，故選擇D。例7 Three fifths of the police_in the school near the town.A. has trained B. have trained C. has been trained D. have been trained分析：分?jǐn)?shù)+名詞做主語時，謂語動詞的形式由分?jǐn)?shù)所指的名詞的形式（可數(shù)名詞或不可數(shù)名詞）決定，police 是集合名詞為復(fù)數(shù)形式，根據(jù)句子意思，police 與train 為被動關(guān)系，應(yīng)用被動語態(tài)，故選擇D。短文改錯片段：1.
