2、nd连接的并列成分作主语时,谓语动词用复数。例如:Both he and I are right.Mr Black and Mrs Black have a son called Tom.但并列主语如果指的是同一人,同一事物或同一概念,谓语动词用单数。例如:His teacher and friend is a beautiful girl.

5、 are my shoes? I cant find them. Your trousers are dirty. Youd better change them. 如果这类名词前用了a pair of等,那么往往用作单数,谓语动词的单复数形式往往取决于pair的单复数形式。例如: Here are some new pairs of shoes. My new pair of socks is on the bed.2. 意义一致的原那么1表时间、距离、价格、度量衡等的名词作主语时,谓语动词通常用单数。例如:Twenty years is not a long time.Ten dollar
6、s is too dear.2有些集合名词,如family, team等作主语时,如作为一个整体看待,谓语动词用单数;如指其中每个成员,那么用复数。例如:My family is big one.My family are watching TV.3不定代词由all, most, more, some, any, none作主语时,也要依这些代词表示的意义来决定谓语动词的单复数形式。如果代词代表复数可数名词,谓语动词用复数;如果代词代表单数可数名词或不可数名词,谓语动词用单数。例如:All of the work has been finished.All of the people have
7、 gone. 4疑问代词作主语时,其谓语动词也有两种情况:主语表示复数意义,谓语动词用复数;主语表示单数意义,那么谓语动词用单数。例如: Who is your brother? Who are League members? 5“分数或百分数+of+名词构成的词组作主语时,其谓语动词要以of后面的名词而定。名词是复数,谓语动词用复数:名词是单数,谓语动词用单数。例如: It is said that 35 per cent of the doctors are women. Three fourths of the surface of the earth is sea.6half, the
8、 rest等表示不定数量的名词作主语时,如果所指为复数意义,动词用复数;如果所指为单数意义,动词用单数。例如: I have read a large part of the book, the rest is more difficult.

9、 a few old books. 8但凡以“定冠词+形容词或分词作主语,往往根据意义一致的原那么决定谓语动词的单复数形式。如果这种主语指的是一类人,谓语动词用复数;如果指的是一个人或抽象概念,谓语动词用单数形式。例如: The sick have been cured and the lost have been found. The dead is a famous person.3. 邻近一致的原那么1由连词or, eitheror, neithernor, not onlybut also,等连接的并列主语,如果一个是单数,一个是复数,那么谓语动词按就近一致原那么,与最靠近它的主语一致
