主谓一致:
一般来说,不可数名词用动词单数,可数名词复数用动词复数,但当不可数名词前有表示数量的复数名词时,谓语动词用复数形式。
主语是单数形式,谓语也采取单数形式;主语是复数形式,谓语必须采取复数形式.
不定式,动名词,以及从句作主语时应看作单数,谓语动词用单数.
不定代词及each作主语或是修饰主语时应看作单数,谓语动词用单数.neither, either,everyone, anyone, someone
表示国家,机构,事件,作品等名称的专有名词作主语时应看作单数,谓语动词用单数.
a series of,a kind of,the number of等与名词构成名词短语作主语时看作单数,谓语动词用单数.(什么的什么)
有些短语,如:a lot of,most of,any of,half of,three fifths of,eighty percent of,some of,none of,the rest of,all of等后接不可数名词,或是单数形式的名词作主语时应看作单数,谓语动词用单数;但如果后接可数名词的复数形式作主语时应看作复数,谓语动词用复数.(量词)
表示时间,金钱,距离,体积,重量,面积,数字等词语作主语时,其意义若是指总量应看作单数,谓语动词用单数;但如果其意义是指"有多少数量"则应该看作是复数,那么谓语动词也应该用复数.
这一原则是指,谓语动词的人称和数常常与最近作主语的词语保持一致.常出现在这类句子中的连词有:or,either… or …,neither… nor …,not only… but also …there be等.例如:
主语由“more than one/a(an)”修饰时,谓语用单数;但如果是“more+名词的复数+than one”这一结构时,后面的谓语动词要用复数。
and的时候同一个概念用单数,不同概念用复数
