一、名詞或代詞作主語(yǔ)時(shí)和謂語(yǔ)之間的單復(fù)數(shù)的一致問(wèn)題：
1.謂語(yǔ)和謂語(yǔ)基本保持單復(fù)數(shù)的一致，即：主語(yǔ)是可數(shù)名詞單數(shù)或不可數(shù)名詞時(shí)，謂語(yǔ)動(dòng)詞用單數(shù)形式：如：The computer was a great invention.(計(jì)算機(jī)是個(gè)了不起的發(fā)明)The water in the glass is very cold.(玻璃杯里的水很冷)
2.集體名詞(如family,class,team,group,row,police,school等)做句子主語(yǔ)時(shí)，
�、� 如果表示整體概念，則謂語(yǔ)用單數(shù)形式，如：Class Three is a very good class.(三班是好班)
② 如果表示其中的所有成員時(shí)，則謂語(yǔ)用復(fù)數(shù)形式，如：Class Three have a map of China.(三 班有張中國(guó)地圖)
3.Chinese,Japanese,fish,sheep,people等表示單個(gè)時(shí)謂語(yǔ)用單數(shù)，表示許多時(shí)，謂語(yǔ)用復(fù)數(shù)。如：There is a sheep in the yard.(院子里有只綿羊)/ There are some sheep in the yard.(院子里有一些綿羊)
4.maths,news等雖然有s結(jié)尾，但不是復(fù)數(shù)，因此謂語(yǔ)仍用單數(shù)：The news is very exciting.(這個(gè)消息令人興奮)
5.glasses,shoes,socks,trousers,gloves等名詞往往用復(fù)數(shù)形式，故謂語(yǔ)用復(fù)數(shù)。如：
The trousers are very cheap and I want to take them.(褲子很便宜，我想買(mǎi))
6.a lot of 后跟名詞復(fù)數(shù)時(shí)謂語(yǔ)用復(fù)數(shù)形式，跟不可數(shù)名詞時(shí)謂語(yǔ)用單數(shù)形式。如：A lot of students are playing baseball now.(現(xiàn)在有許多學(xué)生在打壘球) A lot of time was wasted on that work.(大量的時(shí)間花在了那個(gè)工作上)(被動(dòng)句)
7.and 連接兩個(gè)名詞做主語(yǔ)時(shí)，謂語(yǔ)原則上用復(fù)數(shù)，但是兩個(gè)名詞若構(gòu)成一個(gè)整體事物時(shí)，謂語(yǔ)則用單數(shù)。如：The teacher and his son are picking apples now.(老師和他的兒子在摘蘋(píng)果)/ Fish and chips is very famous food.(魚(yú)和薯?xiàng)l是一種出名的食品)
8. there be 句型中be的單復(fù)數(shù)一般由靠近的名詞決定。如：There is a table and four chairs in the room.(房間里有一張桌子和四張椅子)
9.用both…and…連接兩個(gè)事物做主語(yǔ)時(shí)，謂語(yǔ)一般用復(fù)數(shù)。如：Both you and I are required to be here tomorrow.(你和我明天要求都來(lái))
10.主語(yǔ)中含有with的短語(yǔ)時(shí)，謂語(yǔ)單復(fù)數(shù)由with之前的人物決定。如：A woman with a 7-year-old child was standing at the side of the road.(一名婦女帶著一個(gè)七歲的孩子(當(dāng)時(shí))就站在路邊)
11.either…or…或者 neither…nor…連接兩個(gè)人物做句子主語(yǔ)時(shí)，謂語(yǔ)采用就近原則。如：Either you or he is right.(要么是你對(duì)，要么是他對(duì)。/你和他有一個(gè)人是對(duì)的)/ Neither you nor I am going there.(你和我都不打算去那里)
12.表示一段時(shí)間或長(zhǎng)度概念的復(fù)數(shù)名詞做主語(yǔ)時(shí)，謂語(yǔ)一般用單數(shù)。如：Two months is not a short time.(兩個(gè)月不是個(gè)短時(shí)間)Two thousand kilometers is quite a long distance(距離)(兩千千米是相當(dāng)長(zhǎng)的一段距離)
13.主語(yǔ)中含有half of…/(three quarters)of…/ all(of) the …。等詞語(yǔ)時(shí)，謂語(yǔ)的單復(fù)數(shù)由名詞確定，如：Over three quarters of the information on the Internet is in English.(因特網(wǎng)上四分之三以上的信息是用英語(yǔ)寫(xiě)的)/ A third of the students were playing near the lake.(學(xué)生的三分之一(當(dāng)時(shí))正在湖邊玩耍)/ All of the water in these rivers has been polluted.(這些河流中的水已經(jīng)被污染了)(被動(dòng)句)
但是，population一詞又有特殊情況： What’s the population of China?(中國(guó)人口是多少?)(句子用單數(shù))/ Three quarters of the population in this city are Arabs(阿拉伯人)(這個(gè)城市四分之三的人口是阿拉伯人)(句子用復(fù)數(shù))
