题目

It was only with the help of the local guide__.
A.was the mountain climber rescued.
B.that the mountain climber was rescued.
C.when the mountain climber was rescued.
D.then the mountain climber was rescued.

答案

B 很明显 强调句型嘛
强调句型是这样的：
it is/was +...+that.强调事或物时只能用that
it is/was +...+who.如果强调部分是人的话就用WHO
就只有这两个词
这里指的是事 而不是人 并且选项里也没有WHO的
所以选B
