题目内容
6.-How many classes do you have ______ Friday afternoon?--None.We are free.( )
| A. | in | B. | at | C. | on | D. | to |
分析 -星期五的下午你们有几节课?-一节课都没有,我们很空闲.
解答 答案C.时间介词in+一段时间或固定搭配in the morning/in the afternoon/in the evening;on+星期/节日/具体的某一天/具体某一天的早中晚;at+具体时刻或固定搭配at noon/at night.to连接时间时,通常和from一起搭配,from…to…(从…到…),句中Friday afternoon(星期五的下午)属于具体的某一天,所以答案选C.on
点评 注意区分清楚时间介词on,in,at的用法,分析清楚句子中的时间状语,选择与之相对应的时间介词,多做练习.
