-aha,i can say good bye to english ,to tell you the truth.i haven't a head for english
-but if you_well in english at middle school,you'll find it a hard time tosay in university.
A.haven't done B.don't do C.hadn't done D.didn't do

B.don't do
就是相当于假设了一个情况(即中学没学好英语)

D

haven't done是对的
原因:1.主将从现!即条件句中,主句将来时,从句为现在时
2.不选B是因为很明显句子中AT MIDDLE SCHOOL是假设已经开始发生的,这样他和主句一起表因果关系.用完成式表示已经完成或持续着的状态
明白了吧?^^
