#英语语法# 接上一条继续讲名词的主谓一致和特殊句型固定搭配下的特殊主谓一致用法。这一条是很多孩子比较苦恼的，有点琐碎，多看多用，就会熟练了。

4、名词或代词作主语时和谓语之间的单复数的一致问题：

1、谓语和谓语基本保持单复数的一致，即：主语是可数名词单数或不可数名词时, 谓语动词用单数形式：如：The computer was a great invention. / The water in the glass is very cold. (玻璃杯里的水很冷)

2、集体名词(如family, class, team, group, row, police, school等)做句子主语时,
①如果表示整体概念，则谓语用单数形式, 如：Class Three is a very good class.
②如果表示其中的所有成员时，则谓语用复数形式, 如：Class Three have a map of China.

3、Chinese, Japanese, fish, sheep, people等表示单个时谓语用单数，表示许多时，谓语用复数。如：There is a sheep in the yard. / There are some sheep in the yard.

4、maths, news等虽然有s结尾，但不是复数，因此谓语仍用单数：The news is very exciting.

5、glasses, shoes, socks, trousers, gloves等名词往往用复数形式，故谓语用复数。如：
The trousers are very cheap and I want to take them.

6、a lot of 后跟名词复数时谓语用复数形式，跟不可数名词时谓语用单数形式。如：A lot of students are playing baseball now. / A lot of time was wasted on that work.

7、and 连接两个名词做主语时，谓语原则上用复数，但是两个名词若构成一个整体事物时，谓语则用单数。如：The teacher and his son are picking apples now./ Fish and chips is very famous food.

8、 there be 句型中be的单复数一般由靠近的名词决定。如：There is a table and four chairs in the room.

9、用both…and…连接两个事物做主语时, 谓语一般用复数。如：Both you and I are required to be here tomorrow.

10、主语中含有with的短语时，谓语单复数由with之前的人物决定。如：A woman with a 7-year-old child was standing at the side of the road.

11、either…or…或者 neither…nor…连接两个人物做句子主语时，谓语采用就近原则。如：Either you or he is right. /你和他有一个人是对的) / Neither you nor I am going there.

12、表示一段时间或长度概念的复数名词做主语时，谓语一般用单数。如：Two months is not a short time. / Two thousand kilometers is quite a long distance(距离).

13、主语中含有half of… / (three quarters)of… / all (of) the …. 等词语时，谓语的单复数由名词确定，如：Over three quarters of the information on the Internet is in English. / A third of the students were playing near the lake./ All of the water in these rivers has been polluted. (被动句)
但是, population一词又有特殊情况： What's the population of China?(句子用单数) / Three quarters of the population in this city are Arabs(阿拉伯人). (句子用复数)
