a couple of 后谓语动词形式

Question

如题所述

Answer 1

a couple of+n(c).作主语时谓语动词通常用单数。

它有两个含义

1、两个

There is a couple of boys waiting for you.

有几个男孩在等你。

2、一些，几个

I don't know why I feel so tired,I only had a couple of drinks.

我不知道为什么我这么累，我只喝了几杯。

英语中主谓一致原则

一般现在时态中谓语和主语必须在人称和数上保持一致，最基本的原则是：单数主语用单数动词，复数主语用复数动词，但在实际使用当中情况比较复杂，比如以下例子：

1、"more than one +单数名词＂作主语时，谓语动词常用单数，例句：

More than one teacher gets the flowers.

不止一个教师得到了花。

2、"many a +单数名词＂作主语时，从意义上看是复数，但谓语动词常用单数，例句：

Many a student has been sent to plant trees.

很多学生被派去植树。

3、"half of,the rest of,most of,all of及百分数或分数＋of等后接名词＂作主语时，谓语动词形式根据of后的名词而定，例句：

Three fourths of the surface of the earth is covered with water.

地球表面四分之三为水所覆盖。

Three fourths of the students in our class are boys.

我班四分之三的学生是男生。

Answer 2

通常a couple of后面用复数名词,它的意思相当于a few.a couple of days的意思相当a few days.这类词组作主语时,谓语动词常用复数形式,例如：A couple of/ a few days have passed.但用于there be的句型时,因为习惯上要遵循就近一致的原则,所以一般用单数的动词形式,例如：There is a couple of vacant rooms behind the office.

Answer 3

A couple of 经常跟可数名词复数，整体当做复数看待，谓语动词用复数含义。本回答被网友采纳
