题目内容
20.If Jack _____ free tomorrow,he _____ to the museum with us.( )| A. | will be,will go | B. | will be,goes | C. | is,will go | D. | is,goes |
分析 如果杰克明天空闲,他就会和我们去博物馆.
解答 答案:C.if引导的是条件状语从句,遵循主将从现的规则,从句主语Jack三单,故is,主句一般将来时will+动词原形,故答案是C.
点评 条件状语从句通常由if(如果),unless(除非),as long as(只要)引导.
例如:If it rains tomorrow,we won't go to the park.如果明天下雨,我们就不去公园了. Unless weather stops me,I go for a walk every.我每天都会去散步,除非遇上坏天气
