5. How can the speed of cars be slowed down on highways?
5. 如何使汽车在公路上减速？
The most effective way to slow down car speed,in my opinion,is to issue a decree that a certain amount of fine should be paid when a driver is speeding. I know that in both Europe and America, drivers pay lots of attention to their driving speed so as not to get a ticket. Besides,the driver who breaks the law three times or more should have his driving license revoked and take some courses on driving.
最有效的方法是降低车辆的速度，在我看来，颁布一项法令，汽车超速应被罚一定的金额。我知道在欧洲和美国，司机很注意他们的驾驶速度以防 拿到罚单。此外，违法3次或更多的司机应当吊销驾照并且接受一些驾驶课程。

It is well-known that all kinds of people tend to buy cars,most of whom are businessmen, sports stars, celebrities and high-salaried clerks. It is quite understandable since their high incomes enable them to do so. And we know that sometimes the brand of his car can show a businessman's social status, which is needed on some occasions in order to obtain a certain contact.However, celebrities buy cars to satisfy not only their travel need but also their hobbies, so some of them may own more than one car. Of course, everything is changing. We can see more and more ordinary people are buying cars or planning to buy cars. The reason why more and more common people tend to own cars is that they want to live a more comfortable life,I think.
众所周知倾向于买车的人中，大多数是商人、体育明星、名人以及高薪的职员。这很容易理解因为他们的高收入使其可以这么做。而且我们知道有时车的品牌可以显示一个商人的社会地位， 这在某些场合是需要的，为了获得某些门路。然而，名人们买车不仅为了满足旅行的需要还有他们的爱好，因此他们中某些人拥有不止一辆车。当然，一切都在变化。我们可以看到越来越多的普通人在买车或计划着买车。我认为越来越多的普通人倾向于买属于自己的车，是因为他们想要生活过得更舒适。
