as...as 中的省略与倒装
请问
He is as responsible a man as are you.
1.可不可写成He is a man as resposible as you (are)?
2.如果写成 He is as responsible a man as you (are).还对么?为什么
另外,
3.He has written more essays than I 这句话是不是省略了 （have）
4.能不能倒装变成 he has written more essays than have I.
因为 On the whole,ambitious students are more likely to succeed in their studies than ARE those with little ambition.这里面就倒装了,是因为主语很长么?
