With the development of society, people’s living standard has got great improvement. There are more and more people having private cars. Almost every family has one car. But every coin has two sides. Private car bring many advantages to our human beings, but it also brings many disadvantages to us. There are several reasons counting for my view.
随着社会的发展，人们的生活水平得到了很大的改善。有越来越多的人拥有私家车。几乎每个家庭都有一辆。但是每枚硬币都有正反两面。私家车给我们人类带来很多的好处，但也给我们带来了很多劣势。有几个理由可以支持我的观点。
On the one hand, private car bring great convenience to us. We can go everywhere we want with a private car. We don’t need to queue for a bus and squeeze in the bus. We also don’t need to worry about the distance of our destination. We can make it without striking a blowing with a private car. Besides, staying in the private car is very comfortable. We won’t face the sunshine and rain directly and we can have air-conditioning in the car. Owing a private car has so many benefits.
一方面，私家车给我们带来了很大的便利。有了私家车我们可以去任何我们想去的地方。我们不用排队等公交车也不用挤公交车。我们也不需要担心目的地的距离。有了私家车我们可以毫不费力地做到这些。此外，在私家车也是很舒服的。我们不用被风吹日晒，而且车里面也有空调。拥有一辆私家车真的有很多好处。
On the other hand, private cars also left many problems to us. The most obvious is that it joins hands in the traffic jam. As there are many private cars on the road, in the street, but the road is too small to hold them, so traffic jam comes out. Traffic jam affects everyone out. We all know that the off-gas from private car is harmful to the air that we breathe. Because of it, many people get ill. 
另一方面，私家车也给我们留下了许多问题。最明显的是在交通堵塞方面。因为在路上和街上有很多的私家车，但道路却太小去容纳它们，所以交通堵塞了。交通堵塞影响到每个人的出行。我们都知道私家车尾气对我们所呼吸的空气是有害的。很多人为此而生病。
In a word, though private car brings pros to us, it also brings cons to us.  For the sake of our human beings’ long term development, we need to use cars properly, take the bus to work more.
总之，虽然私家车给我们带来的好处，也给我们带来了坏处。为人类的长远发展着想，我们需要正确使用汽车，多做公交车去工作。
