题目内容
13.Parents who look to having a second child are facing a dilemma.This is ________many of them have passed their"golden age".( )A. | why | B. | how | C. | because | D. | whether |
分析 想生二胎的父母面临着一个困境;这是因为他们中很多人已经过了黄金年龄.
解答 答案为C.本题考查名词性从句中引导词的运用.题干空格后面是be 动词后面的表语从句,第一句中分析的是"想生二胎的父母面临着一个困境",第二句分析"原因";This is because 表示"这是因为…";从句中为具体原因;"This is why"表示"这是…的原因",从句中需要的是具体的结果,不符合语境,故选C
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.
