典型易错题归类分析

 

下面这道题是考查非谓语动词、状语从句还是祈使句?

_______ your composition carefully, some spelling mistakes can be avoided.

A. Having checked                        B. Check          

C. If you check                            D. To check

【陷阱】几个干扰项均有可能误选,尤其可能误选A(from www.nmet168.com)

【分析】最佳答案选 C。前面一个分句为条件状语从句,后面一个分句为主语。现分析几个干扰项:选项 A D 均为非谓语动词,根据英语语法习惯,非谓语动词作状语时,其逻辑主语应与句子主语一致,而此句的 some spelling mistakes 显然不能用作 having checked to check 的逻辑主语,故不能选为答案;若选 B,则两个句子之间缺少必要的连词,也不对。请做类似试题(答案均选 C)
