关于非谓语动词的问题..1.Some activists suggest people have been led to

一些激进派人士暗示现在人们已经趋向于相信大量对环境造成影响的危险已经消失了.
只能选择动词原形,做这样的题目看动词,什么样的动词跟不同的非谓语形式,这里的led
是lead sb to do sth 使...做某事,后面当然用believe了
好吧,我再给你全面解析一下句子.
这样啊,首先把句子分解
Some activists（主语） suggest （谓语）people have been led to_believe that a lot of dangers to the environment have gone away（全部都是省略了that的宾语从句部分）
简单句就是sb suggest sth.这清楚了吧.
再分析一下宾语从句部分
people have been led to believe that a lot of dangers to the environment have gone away
这又是个复合句,和上句一样,that a lot of dangers to the environment have gone away是believe的宾语从句.
简单句就是people have been led to believe sth.
看样子你迷惑的就是这点,这是个被动形式啊.
主动形式是
STH have been led people to believe that...
lead sb to do sth 是个固定用法,意思是使
What led him to resign his office?
什么事导致他辞职的?
lead后面跟不定式,所以在此句中不就是
STH led people to believe吗?
某事使人们相信
再回到被动上去不就是
people have been led to believe （by sth)that a lot of dangers to the environment have gone away
做非谓语的题目的时候主要就是看谓语动词,什么样的谓语动词跟不同的非谓语形式
有的只可以加to,有的只可以加ing,有的都可以意思一样,有的都可以意思不一样,这就是固定的了,需要长期记忆.
