题目内容
4.At present,we have come to sense that creativity is _____ it takes to keep a nation highly competitive.( )A. | what | B. | why | C. | how | D. | that |
分析 现在,我们意识到创造力是保持全国竞争力的重要因素.
解答 答案A.
分析句子结构可知,主句为"we have come to sense","that creativity is _____ it takes to keep a nation highly competitive"为宾语从句;再分析宾语从句的结构可知,"_____ it takes to keep a nation highly competitive"在宾语从句中作表语,表语中动词"take"后缺少宾语,因此要用连接代词"what"引导表语从句,故选A.
点评 本题考查名词性从句.解答此类题目首先要读懂句意和分析句子结构,其次判断是名词性从句中的哪一种从句,然后再分析从句中的成分,如果从句中缺成分且不指代人时一般用what.
