One possible version:
Recently the Students Union has made a survey about what is happiness among 100 students of our school. 32 percent of the surveyed students think that wealth is happiness because they think they can buy anything they want if they have much wealth. On the other hand, 45 percent of them hold the view that they should be in good health so that they can enjoy whatever they like. However, the rest 23 percent students believe that knowledge will bring him a bright future, and he feels happy. From the survey I know that different people value happiness in different ways and as for me, my happiness exists in my study.
最近，学生会对我们学校100名学生的幸福感进行了调查。百分之32的被调查的学生认为财富是幸福的，因为他们认为如果他们有很多的财富，他们可以买任何他们想要的东西。另一方面，百分之45的人认为，他们应该是在良好的健康，使他们可以享受任何他们喜欢的。然而，其他百分之23个学生相信知识会给他带来一个美好的未来，他感到快乐。从调查中我知道，不同的人以不同的方式和我的幸福，我的幸福存在于我的学习。
