题目内容
20.It is not clear ___________ the newly-elected president will do to solve the tricky problem.( )A. | what | B. | whether | C. | which | D. | how |
分析 还不清楚新当选的总统会采取什么措施解决这个棘手的问题.
解答 答案为A.本题考查名词性从句中引导词的运用.题干中it为形式主语,逗号后面的主语从句中缺少的是及物动词do的宾语;what在名词性从句中可做主语、宾语、表语或定语,表示"所、什么";故答案是A.whether在名词性从句中不担任成分;which表示选择;how不做宾语,故排除B、C和D.
点评 名词性从句考查的关键是连接词的选用和语序,因此,我们首先要搞清从句的性质,掌握各连接词的用法,在此基础上判断.此外,关注名词性从句用陈述语序.
