means作主語時謂語動詞用單數(shù)還是復(fù)數(shù)

means 表單數(shù)意義還是復(fù)數(shù)意義? 用作主語時，謂語動詞用單數(shù)還是復(fù)數(shù)？如：

All possible means __________ been tired.

Every possible means __________ been tired.

A. have，have                        B. has，has                        C. have，has                         D. has，have

此題應(yīng)選C。名詞means(方法)的單復(fù)數(shù)同形，用作主語時，其謂語的單復(fù)數(shù)要視具體含義而定：

1. 如果means與all，such，these，those等詞連用，則其含義應(yīng)該是復(fù)數(shù)：

These means are very good. 這些方法很好。

Such means sound interesting，but in fact they’reimpossible. 那樣的方法聽起來有趣，但實(shí)際上是不可能的。

2. 如果means與a，such a，this，that，every等詞連用，則其含義應(yīng)該是單數(shù)：

Such a means is really unpleasant. 這樣的方法確實(shí)是令人不愉快。

There is an effective means of doing it. 做此事有一種很有效的方法。

3. 有時從句意和上下文無法確定means 到底是單數(shù)還是復(fù)數(shù)，則其謂語用單數(shù)或復(fù)數(shù)均可以：

做這事還有其他的什么辦法嗎?

正：Are there any other means of doing it?

正：Is there any other means of doing it?

沒有好的方法。

正：There is no good means.

正：There are no good means.
