题目内容
12.-I'm very tired these days because of walking to school every day.-________ useful exercise you are taking!It can help you keep healthy.( )
| A. | What | B. | How | C. | What a | D. | What an |
分析 -近段时间因为每天步行去学校,我很累.
-你正在做着多么有用的锻炼!它能帮助你保持健康.
解答 答案:A 根据useful exercise可知,感叹修饰的中心词是名词短语,应该用What引导;又根据感叹句的句式:What+形容词+不可数名词+主+谓!exercise做"运动"讲时是不可数名词,所以前面不加冠词,故选A.
点评 注意区别:What+形容词复数名词+主+谓!What+形容词+不可数名词+主+谓!What+a/an+形容词+单数名词+主谓!How+形容词/副词+主+谓!
