work hard,or you will not pass the exam 其中还有的语法

这是【祈使句,and + 陈述句（常用will + 动词原形）】句型在这个句型中,前面的祈使句表条件如：Work hard,and you'll catch up with him。=If you work hard,you'll catch up with him。补充：如果条件部分带否定意味,中间并列连词用or,即：【祈使句,or + 陈述句（常用will + 动词原形）】如：Work hard,or you won't catch up with him=If you don't work hard,you won't catch up with him。
