火龙 电影1986:关于consider的一个问题,大家帮帮我吧!

来源:百度文库 编辑:杭州交通信息网 时间:2024/05/01 22:00:56
Have you ever considered playing any musical instrument? 和He's generally considered to have the finest voice.都是consider为什么一个用不定式一个用进行时?请详细回答,谢谢.

前一个是主动句。you consider doing sth你考虑做某事。
后一个是被动局。he is considered to have sth,原型是consider sb to have sth,认为某人拥有某事。

consider是及物动词,其后要用-ing短语(doing sth.),而不是不定式(to do sth.),例如:

I considered going to see Paul in winter.我考虑冬天去看保罗。

We have considerd doing a tomato experiment.我们已经考虑过做西红柿实验的问题。

consider后还可以跟“疑问词+不定式”(如how/when to do)。例如:

I considered when to go to see Paul.我考虑过何时去看保罗的问题。

We have considered how to do a tomato experiment.我们已经考虑过如何做西红柿实验的问题
