The Elevator
Modern inventions have brought great convenience to people.such as the elevator.Today nearly every concrete building has at least one elevator,and it serves the people all the time.
The elevator has been very helpful to the people in the building,as they can get to any floor within several minutes and without any strain,which otherwise will take them much time and energy.
While enjoying the rapidity and ease of the elevator,we shouldn't only depend on it.The stairs provide the opportunity to exercise,so why not take it if not in a hurry?Furthermore,once something is wrong with the elevator,the whole building will be in trouble as people in it all get used to the convenience it brings,not to mention the danger it may cause.
Generally speaking,the elevator is very useful in our life,but we should utilize it in a proper way.

电梯
现代发明给人们带来很多的方便，如电梯。 现在几乎每一座混凝土建筑物都至少拥有一部电梯，它时时刻刻都在为人们服务。
电梯对大楼里的人们帮助很大，他们可以在几分钟内毫不费力地到达大楼任何一层。 如果不坐电梯，他们就要花费很长时间和很大精力来完成这件事。
在享受电梯舒适与快捷的同时，我们不能完全依赖它。楼梯给我们提供了锻炼的机会，如果我们不急，为什么不走楼梯呢?再说，一旦电梯出了毛病，整座大楼就会有麻烦,因为人们已经习惯了电梯的方便。更不要说电梯还可能带来危险了。
电梯在我们的生活中是十分有用的，但我们应该用的得当才好。
