5.I don't know if Alan ______ to our English party tomorrow evening.I think if he _____ free,he will come.( )| A. | comes; will be | B. | will come; is | ||
| C. | comes; is | D. | will come; will be |
分析 我不知道阿兰明天晚上是否参加我们的英语聚会.我想如果他有空的话,他会来的.
解答 答案B 注意if有两个意思,"如果"引导条件状语从句,通常主句用将来时,从句用一般现在时."是否"引导宾语从句,根据"I don't know…"可知这里是引导宾语从句,时间状语tomorrow evening(明天晚上)用于一般将来时,其构成为will+动词原形,即will come; 第二句中if引导条件状语从句,主句用he will come,从句要用一般现在时,主语he,be动词用is,故选:B.
点评 考查if引导的从句,根据句子中的时态和意思来确定动词形式.
