英译汉：

能让动物为我们工作吗?一些科学家认为,总有一天可以训练动物做一些现在人类所做的简单的工作。

他们指出,例如 在一个马戏团,我们可以看见大象,猴子,狗和其他动物做得熟练的东西。也许你已经看到他们在电视或电影中。如果你仔细看,你会发现这个教练总是给动物一块糖果或一片水果作为奖励。科学家们说,许多不同的动物如果他们知道他们将会因为所做的事得到回报，可以训练来做一些简单的工作,。

The Way to Success

Everyone tries to achieve success in his/her career. But some finally attain their aims while others fail. Why？ Some continue their cause to the end through long period of hard struggles, but others are easily disappointed and stop halfway.

Strong will, perseverance and diligence are the three essentials of success. A man of strong will and perseverance always has an inflexible spirit. He sticks to his cause no matter how tough it might be. Life is short and we have too much to do. Without diligence no one can achieve anything. I believe that where there is a will there is a way, and that success belongs to those who can make constant efforts. Don't be afraid of life. Believe that life is worth living, and your belief will help create the fact.
