consider 用法

consider 需要“考虑”

动词consider既意为"考虑；思考"，又意为"以为；认为"，二者的用法不尽相同。

一、consider作"考虑；思考"解时，主要用法如下：

1. consider后可接名词、代词或宾语从句。

Please consider my suggestion.请考虑我的建议。

Have you considered how you could get the help needed? 你曾考虑如何得到所需要的帮助吗？

2. consider后可接"疑问词+不定式"结构，但不能直接接不定式。

We have to consider where to go for our holidays. 我们得考虑到什么地方去度假。

They haven't considered when to hold the sports meeting. 他们还没有考虑什么时间召开运动会。

3. consider后接动词-ing形式。

We are considering going to Canada next summer. 我们正考虑明年夏天去加拿大。

He is considering changing his present job. 他正在考虑调换目前的工作。

二、consider作"认为；以为"时解，后面除接宾语从句外，还可接：

1. 复合宾语(宾语和宾语补足语)。宾语补足语可以是名词、形容词、动词不定式或介词短语。

We consider him the best man for the job.我们认为他是做这项工作的最佳人选。

They considered me too young to join the army.他们认为我太小，不能参军。

Everyone considered him to have broken the window.大家都认为是他打破的窗户。

We all consider her as our best friend. 我们都把她看做是最好的朋友。

2. it+形容词/名词+不定式结构，在该结构中，it为形式宾语，真正的宾语是后面的不定式。

Do you consider it wise to go there by yourself? 你认为你自己去那里明智吗？

We consider it our duty to help you.我们认为帮助你是我们的责任。

请做下面这道试题：

Charles Babbage is generally considered _______ the first computer.

A. to invent

B. inventing

C. to have invented

D. having invented

该题主要考查consider后接复合宾语的用法，为了便于做题可将原被动句还原为主动句：People generally consider Charles Babbage _______ the first computer.

根据上面所讲，可排除B、D两项。由于invent这个动作发生在谓语动词之前，所以应用不定式的完成式。该题的正确答案为C。
