2016职称英语卫生类语法之主谓一致:

逻辑意义一致就是谓语动词的数必须和主语的意义一致(因有时主语形式为单数,但意义为复数;有时形式为复数,但意义为单数)。

1.what,who,which,any,more,all等代词可以是单数,也可是复数,主要靠意思来决定。如:Which is your bag? / Which are your bags? / All is going well./ All have gone to Beijing.

2.表示“时间、重量、长度、价值”等的名词的复数作主语时,谓语动词通常用单数形式,这是由于作主语的名词在概念上是一个整体,如:Thirty minutes is enough for the work.

3.若英语是书名、片名、格言、剧名、报名、国名等的复数形式,其谓语动词通常用单数形式。如:“The Arabian Nights” is an interesting story-book.

4.表数量的短语“one and a half”后接复数名词作主语时,其谓语动词可用单数形式(也可用复数。如:One and a half apples is (are) left on the table.

5.算式中表示数目(字)的主语通常作单数看待,其谓语动词采用单数形式。如:Twelve plus eight is twenty./ Fifty-six divided by eight is seven.

6.一些学科名词是以 –ics 结尾,如:mathematics,politics,physics 以及news,works等,都属于形式上是复数的名词,实际意义为单数名词,它们作主语时,其谓语动词要用单数形式。如:The paper works was built in 1990./ I think physics isn‘t easy to study.

7.trousers,glasses,clothes,shoes,等词作主语时,谓语用复数,但如果这些名词前有a (the) pair of等量词修饰时,谓语动词用单数。如:My glasses are broken./ The pair of shoes under the bed is his.

8.“定冠词the + 形容词或分词”,表示某一类人时,动词用复数。
