consider doing sth为什么不能选A？不是consider将来发生的动作，用不定式吗？consider作动词时主要有以下四种用法: 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?
