【正确答案】[范文]
   
   There is a popular saying that "No pains, no gains." It means that nothing can be gained without painstaking efforts and that no knowledge or skill can be acquired without sweat or toil.
   You don't have to look very far to prove the truth of the proverb. Mozart would not be an accomplished pianist at the age of eight as a result of watching countless hours of TV. Nor would Edison make himself the greatest inventor in the modern world by spending his spare time going to parties or bars. His words "Genius is 99 percent perspiration and one percent inspiration" reveals the secret of thousands of successful men and women. All accomplishments and success come from sustained endeavor.
   This saying has its profound and realistic significance on our college studies. To acquire knowledge in a particular field and to attain any academic goals, great exertion and persistent effort are undoubtedly required because we all know that "No pains, no gains."
