MPA英语一致部分练习

4)单复同形型。这类集合名词的单数形式既可表示单数也可表示复数。作主语时，用单数动词或复数动词均可，有时意义区别不大。

【例如】The school teaching staff are (is) excellent.

The public is (are) requested not to litter in the park.

The teaching profession claim(s) to be badly paid.

这类集合名词常见的有：class, family, team, crew, board, herd, committee, party, jury, enemy, audience等。

根据说话人的心理意向若把这个集合名词所代表的人或事物看作一个整体，就认为是单数，用单数动词；若把它所代表的人或事物看作若干个个体的话，就认为其为复数，用复数动词。

试比较：The football team is playing well.

那个足球队打得非常漂亮。

The football team are shavings bath and are then coming back here for tea.

足球队员们正在洗澡，然后来这里吃茶点。

The family is a very happy one.

那个家庭是一个非常幸福的家庭。

That family are very pleased about the news of William’s success.

全家人对威廉的成功都感到很高兴。

四、时态一致

1)并列谓语的时态一致。

【例如】Yesterday I went shopping, bought some books and had dinner at a good restaurant.

The soldier looked at him, exchanged glances with his comrade and took out the gun.

2)主从复合句的时态一致。

a)主句为现在时、将来时、现在完成时，宾语从句谓语动词时态按情况而定。

【例如】

I wonder what will happen tomorrow.

I wonder what happened to him yesterday.

I wonder what is happening now outside.

b)主句为过去时态，宾语从句一般用过去时态。如果宾语从句说明的是客观真理，用一般现在时。

【例如】

He told me he made a big mistake.

He told me he would go to Beijing the next day.

He told he had finished his task.

The teacher told students that the earth moves around the sun.(客观真理)

3)定语从句和比较状语从句时态不受主句影响。

【例如】

The university where she is studying was founded in 1950.

You now speak English better than you spoke it last year.

4)时间和条件状语从句中，常用现在时表示将来。

【例如】

We will cancel our trip if it rains tomorrow.

I will go to visit the Summer Palace as soon as I arrive in Beijing.
