首先我知道as...as...结构第一个as是副词，第二个as是连词且作成分。

那么以下分析是否正确？

1.He is as tall as she (is).这里as是连词。

He is as tall as her.这里as是介词还是连词？如果是连词，那“高度”怎么能和“她”相比呢？而且为什么用宾格呢？所以用her句话是否正确？

2.同理，关于than：

He is taller than she (is).这里than作成分是连词。

He is taller than her.比较级+than引导从句，后面出现her因此说than是介词是否正确？

3.He has a car as big as a small house.

如果这句话中 把as big as a small house按照形容词短语作定语分析，然后说第二个as是介词。那上面两句话的as tall as her和taller than her能不能也看作是形容词短语，然后说as和than也是介词？

4.以下as和than作连词，括号里的补全和分析是否正确？

This thing is as simple as I think (this thing is). 这里第二个as作括号的表语，代表前面的as  simple。

This thing is simpler than I thought (This thing is).这里than作括号的表语，代表前面的simpler。

He made as much progress as I thought (he made).这里第二个as作括号的宾语，代表前面的much progress。

Computer is more interesting than TV .这里than是连词不是介词，后面省略了is 。

She made as much cars as I.这里as是连词不是介词，后面省略了did。
