Question

Not once has she given in to any difficulty in her life and that's _____ she is a strong­willed woman.

A．why	B．when
C．because	D．where

Answer 1

C

试题分析：考查表语从句。句意：她一生中从未向困难妥协过一次，这就是她是一个有着坚强意志力的女性的原因。is后跟从句作表语，why后跟原因，because后常跟结果。“she is a strong­willed woman”是“Not once has she given in to any difficulty in her life”带来的结果，故选C。
