I.單數(shù)主語(yǔ)：

　　1.當(dāng) every-, some-, any-, no- 等構(gòu)成的不定代詞及 each, either, neither 作主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞為單數(shù)。 Someone has told me about it.

　　Neither of us likes the film.

　　2.當(dāng) every 或 each 位于兩個(gè)由連接詞連接的單數(shù)主語(yǔ)前，謂語(yǔ)動(dòng)詞用單數(shù)。(必記之要點(diǎn)!)

　　Each girl and boy has a nickname.

　　Every man and woman is welcome.

　　3.位于主謂之間的介詞短語(yǔ)不影響謂語(yǔ)動(dòng)詞的數(shù)，謂語(yǔ)動(dòng)詞須和主語(yǔ)一致。常見(jiàn)介詞短語(yǔ)有：in addition to, together with, as well as, along with, but, except, etc.

　　(這是一幾乎所有考試都不愿放過(guò)的重點(diǎn)。)

　　The teacher along with his students is going to the party.

　　His parents as well as his elder sister have come to see him.

　　II.復(fù)數(shù)主語(yǔ)：

　　1.當(dāng)主語(yǔ)由 and 或 both ... and 連接，通常采用復(fù)數(shù)謂語(yǔ)動(dòng)詞。

　　● Both thegirl and the boyare his friends.

　　2.如主語(yǔ)是both, few或主語(yǔ)前有both, few, several, many 等限定詞時(shí)，謂語(yǔ)動(dòng)詞須用復(fù)數(shù)。

　　● Several novels have been written by her.

　　● Both got the news at the same time.

　　3.下列名詞總是復(fù)數(shù)形式且謂語(yǔ)動(dòng)詞必須用復(fù)數(shù)。

　　trousers, pants(褲子)，jeans, glasses, scissors(剪刀)，tweezers(鑷子)，plier(鉗子)，

　　scales (天平)，compasses(圓規(guī))，etc.

　　● The trousers hereare mine.

　　別忘了：如果以上名詞受 “a pair of” “the pair of”修飾時(shí)，謂語(yǔ)動(dòng)詞用單數(shù)。

　　The pair of pants is too dirty.

　　III.單、復(fù)數(shù)的靈活運(yùn)用：

　　1.當(dāng)主語(yǔ)由 neither... nor, either... or, not only ... but also 或 or 連接時(shí)，謂語(yǔ)動(dòng)詞與nor, or, but also后面的詞一致，在英語(yǔ)語(yǔ)法中，這被稱之為“就近原則”。

　　● Neither he nor I am going to the airport.

　　● Not only Mary but also her parents have gone abroad.

　　2.當(dāng)主語(yǔ)前面有 none, all, some, any, most, half, majority等詞時(shí)，謂語(yǔ)動(dòng)詞則根據(jù)主語(yǔ)的具體情況而采用相應(yīng)的單、復(fù)數(shù)。

　　All of the money has been in the bank. (money 是不可數(shù)名詞)

　　All of us have been here.

　　3.“a number of”是復(fù)數(shù)，修飾可數(shù)名詞，謂語(yǔ)動(dòng)詞為復(fù)數(shù)，“the number of”也修飾復(fù)數(shù)名詞，但謂語(yǔ)動(dòng)詞用單數(shù)。(黃金要點(diǎn)!!)

　　● A number of students have passed the exam.

　　● The number of students in this class is 50.
