Question

Mary believed it was just the license number that she had chosen ___ brought her the good luck.

Mary believed it was just the license number that she had chosen ___ brought her the good luck.
A. that B. which C. when D. where

Answer 1

A. that

Mary believed 不用去管,看后面的.

the license number (that she had chosen )显然是定语从句.

而原来的 强调式,强调的是"the license number " 有it ,没有that.

所以,后面少的成分,就是强调式的"it ...that"句型里的that.

原句即: 改为普通宾语从句.
Mary believed (that) the license number (that she had chosen ) brought her the good luck.

Answer 2

A，这里是一个强调句，it was 。。。。that。。。。。
翻译：玛丽认为正是她选择的执照号码给她带来了好运。
这里强调的是the license number。

Answer 3

B
