if you aren't careful,you will have an accident.前面的那个aren't，是什么时候用aren't什么时候用don't

如果是if you ......look out 呢，don't吗？

推荐答案 2011-01-15

如果你再不小心点，可以要出车祸的。are是be动词，而do是助动词。助动词接的是动词，而be动词接的是形容词或者动词ing形式。
例如:
(1)do
I don't like my brother.He always beats me.
我不喜欢我哥哥，他常打我。
其中的like为动词
(2)be(are/is/am)
I'm pretty and everbody loves me.
我是个漂亮的女孩，大家都喜欢我。
其中的pretty是形容词所以接am
Ps.if you don't look out,you will have an accident.
你说的对
