Can you come at 10 a.m on Monday,April 24th?

问题描述:

Can you come at 10 a.m on Monday,April 24th?
April 24th?前不用加on吗?还是说两个时间介词用同样的介词,并且相连,后面的就要变逗号呢?
还有这个 Can the dentist see me now?翻译是牙科医生现在就不能给我看一下吗?
课文注释里有个句子Can‘t the dentist see me now?我想是不是课文印错了。
Can the dentist see me now?应为Can‘t the dentist see me now?

要加on的,on 用在表达具体的时间之前
Can‘t the dentist see me now?
这是反问句,没错的
难道牙医现在不能帮我看看吗?
