我的关于北京的报告

My Report on Beijing

大家好！我是康康。我的奶奶生活在北京40多年了，她亲自见证了北京的变化。

Hi! I'm Kangkang. My granny has lived in Beijing for more than forty years. She has seen the changes in Beijing herself.

在二十世纪六十年代，道路狭窄，没有很多的环形路，城市生活条件差。

In the 1960s, the roads were narrow and there weren't many ring roads. The living conditions in the city were poor.

通常，一个大家庭被挤在一个小房子里。

Usually, a big family were crowded in small house.

很多家庭没有足够的食物，只有少数孩子有机会接受良好的教育。

Many families couldn't get enough food and only a few children had the chance to receive a good education.

生活太艰难了，以致人们没有时间和金钱去享受业余活动。人们通过信件和电报与远方的朋友亲戚保持联系。

Life was so hard that people had no time or money to enjoy leisure activities. People kept in touch with their friends and relatives far away mainly by letter or telegram.

自从改革开放以来，中国得到了迅猛地发展，越来越多的环形路出现了，北京的建筑正变得更高大更明亮。

China has developed rapidly since the reform and opening-up. More and more ring roads have appeared and buildings in Beijing are becoming taller and brighter.

人们的生活条件改善了很多，有各种各样的食物和衣服供选择。People's living conditions have improved a lot. And there are more kinds of food and clothes to choose from.

人们能享受多种业余活动，孩子们不仅能在现代化的学校学习，而且能在网络上学习。

5

People can enjoy more sorts of leisure activities. Children can study not only in modern schools but also on the internet.

此外（更有甚者），通讯正变得更容易更快捷------人们能使用电话、手机、传真机、网络等等。

What's more, communications are becoming easier and quicker----people can use telephones, cellphones, fax machines, the internet, and so on.

北京取得了快速地进步，它已经成功地举办了2008年奥运会。我想，记住过去，立足现在，展望未来是重要的。

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.

玛丽亚：为什么呢？

玛丽亚：另一张相片的家庭非常大，但是看起来，他们的生活条件不是太好。

The family in the other photo is very big. But it seems that their living conditions were not very good.

康康：是的，这是我父亲的全家福。当她还是小孩的时候，我国大多数家庭至少有三至四个孩子。在那时，中国有世界上最多的人口，没有得到很好的发展。

Y es. It's a photo of my father's family. When he was a child, most families in our country had at least three or four children. At that time, China had the largest population in the world and it was not well develop.

玛丽亚：但是近几年来，中国发生了很大的变化。

But great changes have taken place in China in recent years.

康康：是的，中国已经发展了很多，因为独生子女政策，现在大多数家庭只有一个孩子，我家只有我是小孩，我曾经被称为“小皇帝”。

Y eah, China has developed a lot already. Because of the one-child policy,now most families have only one child. I'm the only child in my

8

family, and I used to be a "Little Emperor".

玛丽亚：呃，我认为那样不好，没有人喜欢“小皇帝”。

Er, I don't think that's good. No one likes"Little Emperors'

康康：我的父母亲也不喜欢，所以他们现在对我要求很严格

Neither do my parents. So they are very strict with me now.
