典型强调句易错题分析

典型强调句易错题分析
 
请看下面的题：
_____ was very ______ that little Jim wrote the letter. http://yingyu.chazidian.com
A. It, careful                          B. It, carefully
C. He, careful                        D. He, carefully
【陷阱】几个干扰项均有可能误选，但最有可能误选的可能是A，认为这是一个普通的系表结构，即认为第二空要填形容词作表语。
【分析】其实，此题是一个强调句，其非强调形式为 Little Jim wrote the letter very carefully. 若用 it is … that… 的强调句式强调其中的状语 very carefully 即为上面一题的题干，所以答案应选B。请看下面几例，也属强调结构(from http://yingyu.chazidian.com)：
(1) It was when she was about to go to bed ______ the telephone rang.
A. since        B. as            C. that          D. then
答案选C，被强调成分为 when she was about to go to bed 这一时间状语从句。
(2) It may have been at Christmas _____ John gave Mary a handbag.
A. before      B. who        C. that          D. when
答案选C，被强调成分为 at Christmas，其中的动词 be 采用了 may have been 这一较为复杂的形式。
