it's a long road from zunyi to beijing
will you go with me to the movies if you are not busy tonight?第二个为什么是aren't语感。。。我是语法白痴。if: on condition that; supposing 假如; 如果; 倘若; 要是. (a) (used with the present and present perfect tenses for highly predictable situations 与现在时态和现在完成时态连用表示预料到的情况): 。。反正就算不是if 写成类似 I don't busy...也不是句子啊。。 就是I am not busy...我不忙。do 或don't 后面接名词类的busy 可是形容词。。
