Do youknow if he__to play basketball with us? I think he will come if he ____ freetomorrow.
A comes is Bcomes will be C will comes is D will come will be
A comes is Bcomes will be C will comes is D will come will be
选A,因为前一个if是"是否"的意思,用一般现在时并要注意三单形式,选C的话will情态动词后也应该用原形come.后一个if是"如果"的意思,if领导的从句,主句用将来时,从句就用一般现在时.
