1 、謂語和謂語基本保持單復數(shù)的一致,即:主語是可數(shù)名詞單數(shù)或不可數(shù)
名詞時,謂語動詞用單數(shù)形式:如:
The computer was a great invention. (計算機是個了不起的發(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)做句子主語時,
①如果表示整體概念,則謂語用單數(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,則謂語用復數(shù)形式,如:
Class Three have a map of China.(三班有張中國地圖)
3 、Chinese , Japanese , fish , sheep, people 等表示單個時謂語
用單數(shù),表示許多時,謂語用復數(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 結尾,但不是復數(shù),因此謂語仍用單數(shù):
The news is very exciting.(這個消息令人興奮)
5 、glasses , shoes, socks, trousers , gloves 等名詞往往用復數(shù)
形式,故謂語用復數(shù)。如:
The trousers are very cheap and I want to take them.(褲子很便宜,
我想買)
6 、a lot of后跟名詞復數(shù)時謂語用復數(shù)形式,跟不可數(shù)名詞時謂語用單數(shù)
形式。如:
A lot of students are playing baseball now. (現(xiàn)在有許多學生在打壘
球)
A lot of time was wasted on that work.(大量的時間花在了那個工作上)
(被動句)
7 、and 連接兩個名詞做主語時,謂語原則上用復數(shù),但是兩個名詞若構成
一個整體事物時,謂語則用單數(shù)。如:
The teacher and his son are picking apples now. (老師和他的兒子在
摘蘋果)
Fish and chips is very famous food. (魚和薯條是一種出名的食品)
8 、 there be 句型中be的單復數(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 …連接兩個事物做主語時,謂語一般用復數(shù)。如:
Both you and I are required to be here tomorrow.(你和我明天要求都
來)
10、主語中含有with的短語時,謂語單復數(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.
(一名婦女帶著一個七歲的孩子(當時)就站在路邊)
11、either…or…或者 neither…nor …連接兩個人物做句子主語時,謂語
采用就近原則。如:
Either you or he is right.(要么是你對,要么是他對。/ 你和他有一個
人是對的)
Neither you nor I am going there. (你和我都不打算去那里)
12、表示一段時間或長度概念的復數(shù)名詞做主語時,謂語一般用單數(shù)。如:
Two months is not a short time. (兩個月不是個短時間)
Two thousand kilometers is quite a long distance(距離)。(兩千千
米是相當長的一段距離)
13、主語中含有half of … / three quarters of… / all(of) the…等
詞語時,謂語的單復數(shù)由名詞確定,如:

(因特網(wǎng)上四分之三以上的信息是用英語寫的)
A third of the students were playing near the lake. (學生的三分之
一(當時)正在湖邊玩耍)

水已經(jīng)被污染了)(被動句)
但是,population一詞又有特殊情況:

Three quarters of the population in this city are Arabs (阿拉伯人)。
(這個城市四分之三的人口是阿拉伯人)(句子用復數(shù))
