the day after on next什么意思?
What will you do the day after on next?
Do you have shampoo here?
It is one o'clock sharp.
donderning dates.
You name the time.
He is still in his forties.
上面的句子都是什么意思啊?
He looks much younger than ___
A he is. B he. C he does.
选A?为什么不选C呢?
这么多问题,谢谢了,先!
不好意思，应该是concerning dates.
be动词、系动词、感官动词有什么区别啊？

What will you do the day after on next?你后天做什么?（这句不确定,因为没有见过the day after on next的用法,但估计差不多是这个意思.）
Do you have shampoo here?你这里有洗发膏吗?
It is one o'clock sharp.现在是一点整.
donderning dates.（请确认一下是否拼写有误,实在不知道是什么意思,
You name the time.你定时间吧.
He is still in his forties.他才四十多岁.
选A 是因为原题中的look是系动词,省略的时候也必须用系动词,所以可以用is（be动词是系动词）,但不可以用do,看下面这个句子,He plays football as well as he does.这时候就必须用does,因为它代替的是前面的动词play.
感官动词和be动词都属于系动词.
