You've made great progress in your studies of English,haven't you?

问题描述:

You've made great progress in your studies of English,haven't you?
___yes,but much( )为什么要填remains to be done.
为什么不填remain to do?

You've made great progress in your studies of English,haven't you?
yes,butmuch ramains to be done
这边省略了much progress remain to be done
因为progress是被取得的,是sb make progress,所以用被动语态,用的是不定式的被动语态表示将来
有不会的可以再问我
