consider doing sth的意思是“考虑打算做某事”,一般来说,consider后面会接名词、从句或者动名词,不会出现直接接do或者to do的情况,这样排除AB,又因为是主动语态,选D
consider的具体用法如下：
一、作思考、考虑(=think about)解,后面可接动名词、由how,what等+动词不定式或者从句作宾语.但要特别注意,consider后面不能直接跟动词不定式作宾语.例如:
①We are considering going to Hainan for the Spring Festival.我们在考虑赴海南过春节.
②He has never considered how to solve the problem.他从未考虑过如何解决那个问题.
③Do you consider that we can finish the project ahead of time?你认为我们能提前完成这个项目吗?
二、consider v.还可作顾虑到、顾及、体谅(=take into account)解.这时其后用名词或动名词作宾语.例如:
①All of you should consider the feelings of other people.你们必须顾及到他人的感情.
②Although he has made such a stupid mistake,you should consider his youth.尽管他犯了那样愚蠢的错误,你应该体谅他还年轻.
三、作认为、以为、觉得(=be of the opinion,regard as)解时,后面多接宾语从句,这时一般不接动名词作宾语.例如:
①I consider that he is fit for the position of the manager.我认为他胜任经理的位置.
②We consider that you are not to blame.我们认为这不是你的错.
③He has never considered the fact that his family is not very rich.他从未考虑过他家并不富裕这一事实.
consider作认为解时,后面还可以接一个宾语和一个动词不定式作宾语补足语,构成复合宾语结构,但这种结构的动词不定式主要是to be+名词/形容词;有时也可以是其它不定式,不过这种不定式多用完成时.例如:
①We always consider him to be a weak leader.我们一直认为他是个能力不强的领导.
②They consider Jim (to be) the cleverest boy in their class.他们认为吉姆是他们班最聪明的学生.
③I consider her to have done wonderfully in the final exam.我认为她在期末考试中表现得非常出色.
注:consider作认为解时,后面偶尔也出现接不定式作宾语的情况,不过这时大都用形式宾语it,而将真正的宾语后移.例如:
Do you consider it wise to interfere?你觉得干预是明智的吗?
四、固定结构consider...as/ to be+名词/形容词多侧重于表示经过思考认为……是…….例如:
①We consider his suggestion as having possibilities.我们认为他的建议具有可行性.
②They considered the plan as reasonable.他们认为这个计划是合理的
