题目内容
20.I don't know if she _______ to the party.If she _______,she'll call me.( )| A. | will go,will go | B. | will go,goes | C. | goes,will go |
分析 我不知道她是否参加这个聚会.如果她去,她将会给我打电话.
解答 答案:B.根据:I don't know if she _______ to the party.我不知道她是否参加这个聚会.可知这里的if引导的是宾语从句,if 意为:"是否".根据下文:she'll call me.可知,此处应该用一般将来时态.根据:If she _______,she'll call me.可知此处if引导的是条件状语从句,应该遵循主将从现的原则,即if引导的条件状语从句,用一般现在时表示将来.故选:B.
点评 本题主要考查时态问题,if引导宾语从句时,需要什么时态,就用什么时态;if引导条件状语从句时,从句用一般现在时表示将来.所以要根据句意,来判断if的含义,确定其引导的从句.
