In the day of the competition, I was asked to enter into a studio room, which there was only one person and a piano. The man asked me  sing in front of the microphone, following his piano playing. My mother was waiting for me outside the studio. I thought that I sang better at the time. So when I finished and walked out the studio, my mother asked, “What happened to your voices?

第二节 读写任务（共1小题，满分25分）
阅读下面的短文，然后按照要求写一篇150词左右的英语短文。
According to Shenzhen Daily, the city’s vehicle population has reached over 1 million and 80 percent of the vehicles are private cars.
Nowadays more and more families own private cars. Private cars, as the product of modern civilization, have been playing a vital role in people's daily activities. Firstly, private cars are a convenient means of transportation. You can go wherever you like. Secondly, there is no doubt that private cars will have a great impact on the economic growth. The rapid car industry growth will contribute much to keeping the country's economy growing at a higher rate in the near futrue.
But every coin has two sides. The development of the private cars will bring about a series of problems. For example, the polluted air given off by cars will do great harm to our health, too many private cars will lead to traffic jams and a great deal of energy will be wasted and so on.That is why many people suggest we should go cycling in the city instead.    
However, I think that the advantages of owning a car outweigh the disadvantages. Therefore, it seems to me that China should increase its output of automobiles and enlarge the private car market. We should take advantages of private cars and make them serve us better. Meantime ,we hope that satisfactory solutions to these negative problems will be found soon.
