修改病句 Work hard,or you will pass the exam.

两种改法：
1，if you work hard, you will pass the exam.
2, Work hard or you will not pass the exam.

pass 改成 fail

work hard or you won't pass the exam.

努力学习否则你不能通过考试。

看语境就知道后面应该是否定形式啦。

Work hard,or you will not pass the exam
or表示否则,后面应该与前面的相反.

or----and

两种改法：
1，if you work hard, you will pass the exam.
2, Work hard or you will not pass the exam.
