Tell Tom not to forget _book.And you mustn`t forget_.

问题描述:

Tell Tom not to forget _book.And you mustn`t forget_.

Tell Tom not to forget the book.And you mustn`t forget it.
第一个是特指,用the
第二个是代前面提到的,用it

Tell Tom not to forget the book.And you mustn`t forget it.
这个空格也太小了哈。

Tell Tom not to forget the book.And you mustn`t forget it.

干什么啊??问题呢...
