means用法易錯(cuò)點(diǎn)

有這樣一道題，請(qǐng)看看：

Every possible means ________ been tried，and we find only ________ this means can we do it well.

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

此題應(yīng)選 D。其余幾項(xiàng)均容易被誤選。這里主要涉及名詞means(方式，方法，手段)的用法與搭配：

1. 單復(fù)數(shù)同形(永遠(yuǎn)有詞尾-s)。若用作主語(yǔ)，其謂語(yǔ)的數(shù)需根據(jù)句意來(lái)確定。比較：

All possible means have been tried. 所有可能的辦法都已經(jīng)試過(guò)了。

Every possible means has been tried. 每種可能的辦法都已經(jīng)試過(guò)了。

若句意不能明確地表明主語(yǔ)的單復(fù)數(shù)，其謂語(yǔ)則用單數(shù)或復(fù)數(shù)均可：

Is [Are] there any other means of doing it? 做這事還有其他的什么辦法嗎?

2. 表示以某種方式、方法或手段，用介詞by：

Only by this means can you do it well. 只有通過(guò)這種辦法你才能做好此事。

有時(shí)用 by means of，意為：用……，依靠……：

Thoughts are expressed by means of words. 思想靠語(yǔ)言來(lái)表達(dá)。

3. 表示做某事的方法或手段，多接“of＋(動(dòng))名詞”：

But they had no means of cooking them. 但是他們沒(méi)有辦法來(lái)把它們煮熟。

Taking a plane is the quickest means of getting there. 去那兒最快的辦法是坐飛機(jī)。
