Could I borrow that book when you've finished reading it?
that是代词吗?“you've finished reading it 当你读完后”,怎样理解是现在完成进行时?it 又是指什么?
Could I borrow that book when you've finished reading it?
that book 是一起的,就是“那本书”的意思
整句话意思是:当你已经读完那本书的时候我能借一下么?
you've finished reading it 就是明显的一个现在完成时啊!
it 就是前面提到的“that book”啊
再问: you've finished reading 现在完成进行时吗?那reading是动名词?
再答: 呵呵。不是的 have done sth 这里的have已经跟了finished了呀。然后finish+doing的结构 所以变成了have finished doing sth 啊 再举个例子 I have decided to go to USA. 这里have decided 已经符合have done 的语法了、然后decide+to do sth 综合就变成了have decided to do sth 了、
再问: 还有什么词+doing的结构?
再答: 好多的。一时也说不过来 你初中的吧?多看书。很多句型书里课文里很明显可以找到! 有些词doing 也可以 to do 也可以 但用法不同
