七、状语从句

八、宾语从句
1、how的意思
(1)“多么”。I don’t know how important it is.
(2)“如何”。I don’t know how to solve the problem.
2、what to do和how to do 的区别:
(1)意思不同。
what to do是做什么的意思,而how to do是怎么做的意思。如:
I don't know what to do next 我不知道接着该干什么了。
Could you suggest someone to advise me how to do this? 这该怎么办?你能不能推荐一个人帮我出个主意?
(2)二者的询问对象不同。
what to do"做什么"问的是动作的对象;
how to do "怎样做"问的是动作的方式。
(3)二者后跟宾语情况不同。
what是代词在句中中做宾语,所以what to do中_____________不需要再加宾语。
how是副词,how to do 中how做to do的状语。还________________需要加宾语,how to do it句子才完整。
