Question

mary was the first girl_____when you got here

A:you talked to whom
B:you talked to
C:whom you talked
D:who you talked
分析下这个为什么选B呢，我一点都不会这个题

Answer 1

这里考察的是一个定语从句的问题。当先行词被序数词包括the last修饰时候，引导词只能用that.这里先行词girl ，可用that/who，但是前有the first,故只用that.又因为这里that在定语从句里面的成分不是主语，可以省略。故只能选择答案B

Answer 2

这是个定语从句，先行词是 girl ，从句中girl的做的成分是宾语，所以连接词that或whom可以省略，不省略的话，就是 Mary was the first girl who（that，whom）you talked to when you got here 。A句中whom应该在you的前面，C和D句中talked后面少了 to。

Answer 3

这道题考定语从句，你刚才对话的那个人，是宾语，所以用连接词that，whom，代替宾语的连接词可以省略，所以用B.

Answer 4

you talked to 做girl的定语
A中的whom应放前面
C少to
D少to who有时和whom可以互换

Answer 5

you talked to是the first girl的定语。
