关于被动语态的问题
1.The ancient Egyptians are supposed to have sent rockets to the moon a long time ago.
为什么要用have?
2.Everything taken into consideration,the plan Xiao Wang put forward seems to be more workable.
前半句中的taken是做什么成分?为什么不用be动词?
为什么第一题的be动词不是用过去时？
关于被动语态的问题1.The ancient Egyptians are supposed to have sent rockets to the moon a long time ago.为什么要用have?2.Everything taken into consideration,the plan Xiao Wang put forward seems to be more workable.前半句中的taken
1.be supposed to do sth表示应该去做什么,但是如果表示“过去应该做某事”则要在不定式后边用have done sth. 这里是陈述一个过去的情况,所以用be supposed to have done sth.
2. "everything taken into consideration"并不是主句,这里everything与take的关系是被动进行,("sb. takes everything into consideration")所以用过去分词表示被动关系.
1。这个句子用have done跟被动语态没有关系。因为他要表达很久以前已经做了这事了，而这个事件对现在造成了影响。
2。第二个句子过去分词做伴随状态，因为逗号不能隔开两个句子，所以前半部分不能有谓语动词的存在。
