题目内容
8.-David,could you tell me____________?-Twice a week.( )
| A. | when you do exercise | B. | how often you do exercise | ||
| C. | how many times you do exercise |
分析 -大卫,你能告诉我多久锻炼一次吗?-一周两次.
解答 正确答案:B.A是你什么时候锻炼,B是你多久锻炼一次,C是你锻炼多少次.Could you tell me…是一个宾语从句,三个选项引导词都不同,那么根据答语Twice a week可知是频率的提问,故选择B.注意how often是询问频率,多久,而how many times强调次数,总共多少次.
点评 本题考查宾语从句,根据答语即可作出选择.C项是干扰项,所以一定要注意how often和how many times的区别.
