一句句子的语法
I would like to propose the alternative time for the interview of the accounting position which will be on 1/11.
I would like to propose the alternative time for the interview of the accounting position,which will be on 1/11.
以上两句的which能用来形容/代表alternative time吗?还是which跟在accounting position后所以就是形容/代表accounting position的?
Could I propose the alternative time for the interview on 1/11 at 9am?
这样表达算正确吗
