求上海2011闵行区英语一模考的作文题目!
答案
题目Is it good for more people to own cars?
我有较好范文
I don’t think it’s good for more people to own cars. Firstly, having more cars will make our city suffer more from traffic jams. Therefore, during the rush hour, travelling on the road will be much harder. On the other hand, having more cars will increase the usage of petrol, and the amount of Carbon dioxide we release, which mainly causes the Greenhouse Effect. People cause more damage to the Earth as they have more cars. A good suggestion is that we can use public transportations more often instead of having more cars.
