题目内容
19.The government is asked to improve school bus safety, ?( )A. | didn't it | B. | hasn't it | C. | isn't it | D. | doesn't it |
分析 政府被要求提高校车的安全,是吗?
解答 答案:C 根据前面的句子可知是一个肯定句.根据反义疑问句的原则,前面是肯定,那后面的反问部分就得用否定.再结合句子中的关键词is asked 可知此句用的是被动语态,结构为be+过去分词,所以这里的反问部分我们可以直接来否定be动词is,缩写为isn't;由于句子的主语为government表物,所以用it代指.综合以上分析,结合选项故选C.
点评 此题考查反义疑问句的用法.做此类题一定要先确定大的原则,那就是前肯后否或前否后肯;再根据句子判断出应用be动词还是助动词或情态动词来反问,最后再加上指代句子主语的代词即可.
