问题：讲一下区别Workhardnexttime,andyouwill 
Work hard next time,and you will sceed.Working hard,you will make it,I believe.为什么第一句用work，而第二句用working?
回答：这涉及到英语中的两个重点语法。
1. 句型结构
祈使句+and，or+将来时的一句话。
如： Work hard and you will succeed. 努力学习，你就会成功。
     Hurry up or you will be late.  快点，否则你就迟到了。
此句型的特点是  祈使句（也就是用动词的原型）
2.非谓语动词---分词做状语
Working hard, you will make it.
主句是 you will make it.  前面的动作 work hard 逻辑主语也是主句的主语you， 所以用ing形式做状语。
此句可以改成： (If you )work hard, you will make it. 

再如： Standing there , you can see him clearly.
     / (If / When you) stand there, you can see him clearly.
