1.某些集體名詞如果作為一個整體來看待，謂語動詞用單數形式，如果表示集體中的個體成員，謂語動詞就要用復數形式。

　　這類集體名詞包括：audience(觀眾)，class(班級)，club(俱樂部)，company(公司)，crowd(人群)，government(政府)，group(團隊)，team(隊伍)等。如：My family is a small one with three people.

　　但people，police，cattle等，只能按照復數對待，謂語動詞必須用復數。

　　如：The people around us are all friendly and helpful.

　　2.當名詞詞組的中心詞表示時間、距離、書名、金額等復數名詞時，把這些復數名詞看作一個整體，謂語動詞用單數形式。

　　如：Ten years for them was so long because they led a working but hard life.

　　3.由“a pair(a kind，a bottle…)+of+復數名詞”作為主語時，謂語動詞要用單數形式，但由“pairs( kinds，bottles…)+of+復數名詞”作為主語時，謂語動詞要用復數形式。

　　如：This pair of shoes is very nice but expensive.

　　4.不定代詞each，every，no所修飾的名詞即使以and或逗號連接成多主語時，謂語動詞仍用單數形式。

　　如：Each boy and each girl was given a new book.

　　5.某些只有復數形式的名詞(glasses，clothes，trousers，shoes，chopsticks，scissors等)，謂語動詞用復數形式。

　　如：Those shoes are put under the desk.

　　6.and或both…and連接并列主語，謂語動詞通常用復數形式。如：Walking and riding are good exercises.

　　但并列主語如果指的是同一個人、同一事物或同一概念，謂語動詞用單數形式。

　　如：A knife and fork is on the table.

　　7.當主語中含有as well as，in addition to，(along)with，together with，except，besides，including等引導的詞組時，其謂語動詞的單、復數依據他們前面的主語而定。

　　如：Jack as well as his parents has been to China before.

　　但either…or，neither…nor， not only…but also和There be出現在句中時，謂語動詞的單復數就要采用就近原則。

　　如：There is a photo and two maps on the wall.

　　Neither her sisters nor Mary is going to the party tomorrow.

　　8. 由“分數+名詞或百分數+名詞”構成的短語以及由“a lot of，lots of，plenty of，a large quantity of，half of+名詞”構成的短語做主語時，其謂語動詞要與短語中of后面的名詞的數保持一致。

　　如：Ten percent of the water is polluted there.

　　9.由a number of+名詞復數做主語時，謂語要用復數形式；由the number of+名詞復數做主語時，謂語要用單數形式。

　　如：A number of people are waiting to be interviewed.

　　The number of students in our class is 50.

　　10.在“one of+復數名詞+who/that/which”引導的定語從句中，從句中的動詞應該是復數形式。但如果the only來修飾one時，從句的動詞應是單數形式。如：This is one of the most interesting stories that have been told.

　　She was the only one of the girls who was late.
