An Important Change at School
A school is an important place to student. It is where they spend the majority of their time during their school years. Therefore， it is important that the school provide a good environment for the students to develop both mentally and physically. For this reasons， if I could make one change to the school I attend， I would add a large， modern gymnasium. One reason I support the building of a modern gym is that physical education class is very important to the well-being of students. It provides us not only with exercise， but with a break from the mental rigors of our studies. However， without a large enough gym， we must often cancel our P.E. class when the weather is bad and more classes must share the indoor space. A new gym would solve this problem. Another reason I would like to have a new gym is that more modern athletic facilities would allow us to practice a wider variety of sports. This would appeal to those students who are not physically active because they find the current sports that we play boring or difficult. In developing the lifelong habit of exercise， it is important for everyone to find something he enjoys. Finally， a big， new gymnasium could be used for other events as well， such as class assemblies and performances. For the reasons given above， I believe that a large， modern gymnasium would be a valuable addition to my school. It would encourage more students to exercise and allow them to do so on a more regular basis. In addition， it could be used by many school organizations and clubs for a variety of purposes. Therefore， I believe it is a practical suggestion.

学校的重大改变
学校对学生而言是个重要的地方，它也是学生在求学期间待的最久的地方。因此，学校应该提供一个良好的环境供学生发展身心，这是很重要的。基于这个理由，如果我能改变我所就读的学校的话，我会增设一座大型的现代化体育馆。
我支持兴建一座现代化体育馆的理由是，体育课对学生的健康是非常重要的。体育课不仅让我们有机会运动，还能让我们远离耗尽心力的学业，以获得暂时的舒解。然而，如果没有一座足够大的体育馆，我们常会因为天气不好或者其他的班级要共用室内空间而取消体育课。一座新的体育馆就能解决这个问题。另一个我想拥有一座新体育馆的理由是，更现代化的体育设施能让我们从事各式各样的运动，如此便能吸引那些认为现在的体育活动过于无聊或困难而不太热衷于运动的学生。在培养终生运动的习惯时，让每个人都能找到自己所热爱的运动是很重要的。最后，一个大型且新颖的体育馆也可用来举办其他大型活动，如班级集会或各种表演。
基于以上理由，我认为增添一座典型且现代化的体育馆对我的学校而言是很有价值的。这会鼓励学生运动，而且还能让他们地运动。此外，它还可以供许多校内团体或社团举办各种不同性质的活动。因此，我认为这是个相当实用的建议。
