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.
隨著社會的發展，人們的生活水平得到了很大的改善。有越來越多的人擁有私家車。幾乎每個家庭都有一輛。但是每枚硬幣都有正反兩面。私家車給我們人類帶來很多的好處，但也給我們帶來了很多劣勢。有幾個理由可以支持我的觀點。
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，私家車給我們帶來了很大的便利。有了私家車我們可以去任何我們想去的地方。我們不用排隊等公交車也不用擠公交車。我們也不需要擔心目的地的距離。有了私家車我們可以毫不費力地做到這些。此外，在私家車也是很舒服的。我們不用被風吹日曬，而且車里面也有空調。擁有一輛私家車真的有很多好處。
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，私家車也給我們留下了許多問題。最明顯的是在交通堵塞方面。因為在路上和街上有很多的私家車，但道路卻太小去容納它們，所以交通堵塞了。交通堵塞影響到每個人的出行。我們都知道私家車尾氣對我們所呼吸的空氣是有害的。很多人為此而生病。
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.
總之，雖然私家車給我們帶來的好處，也給我們帶來了壞處。為人類的長遠發展著想，我們需要正確使用汽車，多做公交車去工作。
