Be careful when you are crossing the street.
这是一个用现在进行时来代替将来进行时的句子,这个句子可以改为you are cross吗,用一般现在时来代替将来时和这个句子区别在哪?

不可以改为you are cross, 这不是一般现在时,一般现在时应该是：you cross.可以改为：Be careful when you cross the street. 意思是：你过马路时要小心.
用现在进行时的意思是：打算/准备过马路时.
另外,你给的这句话不叫将来进行时,就是将来时,将来时有两种形式,一种是：will + 动词原形；
另一种是：be + 动词的ing形式
