问题描述:

mr smith is going to give us a talk-----.A.at this afternoonB.on tomorrow morningC at this evening
Dnext monday morning为何选D

this morning(afternoon,evening), tomorrow前不用介词

不需要介词

this; tomrrow 已是adv.(副词),副词前不用介词修饰

作状语 不加任何介词

morning,afternoon,evening这些表示时间的词,前面是不能加介词的.因此 A B C的用法均是错误的,只有D才是正确用法.
