Example 3: Along with the fast development of our society and the economy, more and more cars are being made and bought.     , on one hand it is a true proof of the greater level of people's lives, On the other hand so many cars have been bringing more and more problems to our environment and traffic system. First of all, cars have been giving off some harmful gases which seriously pollute the air. This leads to the air pollution and will harm our health when we breathe. Next so many cars on the road will produce loud noises, which will disturb our regular life. Besides, cars are driven by burning gasoline, which is limited in the world. In fact, its shortage is more and more obvious. Then when it comes to the traffic, a large number of cars on the road are making the traffic jam really worse. As a result, it results in the waste of energy and the air pollution. We can see that the cars, the environment and the traffic condition are all in a connected chain. We cannot ignore any part of it.

We should look for ways to solve the problems. In my pinion,we can develop the public traffic,especially the buses. Providing convenient and cheap bus service will enable us to make better use of the energy while reducing pollution. Then, promoting the technology of vehicle industry is also necessary since we solve the problems from the very beginning. Building more broad roads may be useful to the traffic jam too. In fact, there are many other methods to solve the problems. Only if everyone is conscious of protecting the environment, the problems won't exist for long.

Brief Comment：三位考生分析问题的思路各有千秋：Example 1的危害归结为社会问题和自然问题，然后通过举例进行分析，最后提出解决这两个问题的关键在于新技术和新立法，可见答题者有一定的逻辑推演能力；Example 2则长于描写现象，在刺耳噪音、交通堵塞、危险事故的描写中使考官自然体会到问题所在，描写用词准确，可以看出答题者较强的表达能力；Example 3采用传统格式，用关联词推动表达思路，显示出较强的语言组织能力。就问题本身而言难度不大，若能使回答独具匠心体现出特色，更能引起考官的关注。比如借鉴西方国家的很多做法：Car. pool（拼车），限制每年plate number（车牌号）的发放,downtown限制或禁止私家车入内，同时加强public transport,如subway的建设等等。
