2个英语上的疑问
这句,Dolly's DNA is exactly the same as that of the sheep she was cloned from.里面为啥会要突然出现个of ?去掉of不行么?
还有What is ink used for ?
It's used for writing in. 为啥句尾要有个in ?麻烦详细解释一下,谢谢.
of是所有格,前面有个Dolly's DNA,与后面的that of the sheep相对应,不能去掉.
意为 多利的DNA和他所克隆的羊的DNA是完全相同的.
ink本身是不能写字的,要放在笔里才能写字,所以加in.
如果是what is pen used for?回答就可以是 It's used for writing.
