此題是考查強(qiáng)調(diào)句式嗎

下面這道題是考查強(qiáng)調(diào)句式嗎？

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

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

【分析】此題容易誤選A，受空格前逗號的影響，誤認(rèn)為這是一個(gè)非限制性定語從句，從而誤選了A。其實(shí)，此題最佳答案為C，整個(gè)句子為一個(gè) it was…that…結(jié)構(gòu)，就是強(qiáng)調(diào)句，被強(qiáng)調(diào)成分為 lack of money, not of effort。由于句中插入 not of effort 這一結(jié)構(gòu)，干擾了許多同學(xué)對 it was lack of money that defeated their plan. 這一強(qiáng)調(diào)句的認(rèn)識和分析。
