Which of the following infinitives(不定式)indicates CAUSE?

A、 She wept to see him in that condition.
B、 He picked up the phone to call his wife.
C、 She grew up to be a famous scholar.
D、 My wife used a knife to cut the cake.

【正确答案】 A

【答案解析】考查不定式的用法。A的to see him in that condition用以说明wept的原因，相当于原因状语从句，即She wept because she saw him in that condition．故为本题答案。B、D的不定式表目的，C则为结果状语，意为“她长大后成了有名的学者”。
