问题描述：
---What're these? ---( ) A.They're boxes. B.These're boxes C.It's boxes
答
A
B的these 不能与are缩写why?因为B 选项，如果是These are boxes就对的，他们不能缩写而C的话复数不能用it's老师答案给的是A，why？原因就是我刚才说的，B中these 与are 不能缩写C单复数错掉本题实际上就是考察these are这个的缩写问题they're 它们是These are这些是这两个都可以回答本题，但B中用了缩写，所以不行B那样写是我打题图方便才那样的，原来是These are boxes.如果硬要说这两个的区别的话these are这些,通常在开始即第一次提到是会用到.再次提到则用they are其实这两种说法指代的都是相同的事物.与此类似的还有.this/that is与 it isThese are books,they are English books.That is my car,it is from Japan
