做个好学生，做完作业再出去玩。

.  英译汉：

1.1.  "Success is not final; failure is not fatal: It is the courage to continue that counts." -Winston S. Churchill
成功和失败都不是终极目标，重要的是不停地追求。
1.2  "In the end, it's not the years in your life that count. It's the life in your years." -Abraham Lincoln
最终重要的不是你活了多少年，而是你怎样活着
1.3  "The greatest glory in living lies not in never falling, but in rising every time we fall." -Nelson Mandela
最值得骄傲的不是你从没有跌倒，而是每次跌到后，你都站起来。
2.  汉译英：
天下只有两种人。比如一串葡萄到手，一种人挑最好的先吃，另一种人把最好的留到最后吃。照例第一种人应该乐观，因为他每吃一颗都是吃剩的葡萄里最好的；第二种人应该悲观，因为他每吃一颗都是吃剩的葡萄里最坏的。不过事实却适得其反，缘故是第二种人还有希望，第一种人只有回忆。
There are only two types of person in the world. Suppose there is a a cluster of grapes, one will pick the best to eat first, the other one will save the best to eat in the end. we might think  that the first person will be optimistic because each grape he eat is alway the best among the remaining grapes and the second person will be percimistic because each grape he eat is alway the worst. But In fact, this is not true because the second person alway has hope and the first person only has memory.
