英语语法强调句知识点：此题是考查强调句式吗

下面这道题是考查强调句式吗?

It was lack of money, not of effort, _________ defeated their plan.

A. which B. as C. that D. what

【分析】此题容易误选A，受空格前逗号的影响，误认为这是一个非限制性定语从句，从而误选 了A。其实，此题最佳答案为C，整个句子为一个 it was…that…结构，就是强调句，被强 调成分为 lack of money, not of effort。由于句中插入 not of effort 这一结构，干扰了许多同学对 it was lack of money that defeated their plan. 这一强调句的认识和分析。
