题目内容
9.You won't win the singing competition if you try your best.( )| A. | aren't | B. | don't | C. | didn't | D. | won't |
分析 如果你不做到最好,你不可能赢得这个唱歌比赛的.
解答 答案:B,主句比赛发生在未来,是将来时;对于if引导的条件状语从句,一般用现在时表示将来,所以排除C两个选项.而此处需要填的否定助动词与动词try相对应,所以不能用aren't,所以选择B.
点评 考察词类型活用和语态的基本知识,在了解句子大意的基础上,根据状态的持续性或发生时间选择正确的时态.
