Section C
Changes in Beijing
I'm Kangkang. For this report I have interviewed my grand-mother. She has lived in Beijing for more than forty years. She has seen the changes in Beijing herself.In the 1960s, the living conditions in the city were poor. The roads were narrow and there weren't many ring roads. Big families were crowded into small houses. Many families couldn't get enough food. Few children had the chance to receive a good education. People had little money to see a doctor. And there were few hospitals. People kept in touch with their friends and relatives far away mainly by letter or telegram.China has developed rapidly since the reform and opening-up. More and more ring roads and subways have appeared and buildings in Beijing are becoming taller and brighter. People's living conditions have improved a lot. And there are more kinds of food and clothes to choose to satisfy people’s needs. Children can study not only in modern schools but also on the Internet. People can enjoy good medical care. What's more, communications are becoming easier and quicker--people can use telephones, cellphones, fax machines and the internet.Beijing has made rapid progress and it has already succeeded in hosting the 2008 Olympic Games. I think it is important to remember the past, live in the present and dream about the future.
我是康康。为了这份报告，我采访过我的奶奶。她已经在北京居住四十多年了。她亲自眼目睹了北京的变化。在20世纪60年代，城市的生活条件较差。道路狭窄并且没有很多的环形公路。一个大家庭挤在一间小房子里。许多家庭得不到足够的食物，极少的孩子有机会接受良好的教育。人们几乎没有钱去看医生，而且医院很少。人们主要靠信件或电报与远方的亲友保持联系。自从改革开放以来，中国发展迅速。出现了越来越多的环形路，并且北京的楼房变得又高又明亮。人们的生活条件有了很大改善了。可供人们挑选的食品和衣物的种类也越来越多。孩子们不仅能在现代化的学校里学习，而且还能在网上学习。人们可以享受更好的医疗保健。另外，通讯更加方便快捷---人们可以用电话、手机、传真机和网络方式（联系）。北京取得了快速的进步，它还成功举办了2008年的奥运会。我认为记住过去、立足现在、展望未来非常重要。

Section C
In 2010, the world's population was about 6.8 billion. More than three billion people live in Asia now. That's almost half of the world's population.
China has the largest population in the world, and about one fifth of the people in the world live in China. Because of the large population, there is less living space for each family. And it is difficult for lots of people to find jobs. At the same time, the large population has caused many other difficulties for the whole nation. For example, it is hard for China to supply energy and the traffic is much heavier. Natural environment are becoming worse and worse. The large population has been a serious problem.
So far, our government has taken many measures to control the population. One is known as the one-child policy. It has worked will in controlling China's population. Thanks to the policy, China is developing quickly and people's living conditions are improving rapidly. However, the population problem is still serious in China. We still have a long way to go.
2010年，世界人口大约是68亿。现在30多亿人居住在亚洲。这几乎是世界人口的一半。
中国是世界上人口最多的国家，世界上大约五分之一的人居住在中国。由于人口多，每个家庭的居住面积更小了。并且许多人找工作都很困难。.同时，人口多也给整个国家带来了许多其他的困难。例如，中国很难提供足够的能源和水来满足人们的日常需求。大多数城市比以前更拥挤，交通堵塞更严重。自然环境越来越糟糕。人口过多已经成为一个严峻的问题。
到目前为止，我们政府已经采取许多措施来控制人口增长。其中一项众所周知的就是独生子女政策。它在控制中国人口数量方面有了显著的成效。多亏了这项政策，中国正在迅速发展，人们的生活条件也在迅速改善。然而，人口问题在中国仍然很严峻，我们仍然有很长的路要走。

in the morning, I went to the countryside with my classmates. On the way we saw many rice fields and woods on both sides of the road. Farmers have built factories, shops and schools in many villages. Between ten and twelve we visited ten families. Many farmers who grew vegetables and raised silkworms became rich. Some families have bought color TV. Their life is much better than before. It’s said that some American friends will come to visit their village, too. I hope the farmers’ life will be better and better.
