这篇文章小编给大家总结归纳了中考英语的重要知识点,接下来分享具体内容,供参考。
1.语法一致的原则
(1)以单数名词或代词,动词不定式短语作主语时,谓语动词要用单数;主语为复数时,谓语用复数,例如:He goes to school early every morning.
(2)由and或both……and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.
(3)由and连接的并列单数主语之前如果分别由each, every修饰时,其谓语动词要用单数形式。例如:In our country every boy and every girl has the right to receive education.
(4)主语是单数时,尽管后面跟有 but ,except, besides, with 等介词短语,谓语动词仍用单数。例如:The teacher with his students is going to visit the museum.
(5) 一些只有复数形式的名词,如people, police, cattle, clothes等作主语时,谓语动词要用复数。例如:A lot of people are dancing outside.
(6)由each, some, any, no, every 构成的复合代词作主语时,谓语动词都用单数。例如:Is everybody ready?
(7)有两部分构成的物体的名词,如glasses, shoes, trousers, chopsticks, scissors 等作主语时,谓语动词用复数。例如:Where are my shoes? I can’t find them.
2.意义一致的原则
(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.
(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,则用复数。例如:My family is big one.
(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.
(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,则谓语动词用单数。例如:Who is your brother?
(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.
