Every year, tens of thousands people crowd into the big cities to seek a decent living, a better job, a faster and more exciting life style. Take Beijing as an example, according the least research, the population in Beijing is more than twenty millions, and of 40% of them is not local. With the rapid growth of urban population, these big cities have many problems on their own.
每一年，成千上萬的人涌入大城市去尋找體面的生活，更好的工作，更快更刺激的生活風格。以北京為例，通過最新的調查結果顯示：該城市人口超過2000萬，其中40%不是本地人口。隨著城市人口的快速增加，這些大城市存在各種各樣的問題。

The first problem is with more and more people flooding into the cities, the cities infrastructure such as public transportation, hospitals and school, can hardly meet the people’s need. The streets are full of private cars, traffic jams can be encounter at any moment. The hospitals are full of patients because the doctors are not enough. The housing price is extremely high that most people can not afford one with their whole life salary. It seems that the cities are on the brink of breaking down.
第一個問題就是隨著越來越多的人進入城市，城市的基礎設施比如公共交通、醫療設備及學校，很難滿足人們的需求了。大街上都是私家車，隨時隨地都可能遭遇堵車的危險。醫院里擠滿了病患，因為醫生忙不過來。房價特別的高，大多數人賺一輩子的錢都不能買到屬于自己的房子。看起來，城市處在崩潰的邊緣。

The second problem is the nature environment of cities. The air pollution, fresh water shortage and noise pollution are worse than ever. In order to have more space to build skyscrapers and infrastructure, trees are cutting down and lakes are land filling. The endless flow traffic makes harsh noise that people even can not sleep well at night. What’s worse, the fog and haze is surrounding the cities, the children can not go outside to play, the people have to put on breathing masks if they go outside. The air of the cities is unbreathable to some extent.
第二個問題是自然環境問題。空氣污染、淡水短缺、噪音污染比之前更為嚴重。為了能有更多的空地建造摩天大樓和基礎設施，樹木被砍伐。湖泊被填埋。川流不息的車子發出刺耳的噪音，人們在晚上都不能睡個好覺。更為嚴重的是，霧霾籠罩著整個城市，小孩子不能出去玩，人們出門一定得帶口罩。城市中的空氣，從某種程度上來說，已經不能供給人們呼吸了。

There are also other problems, the crime rate. As competition intensifies, some of the people can not find a job, thus they do some illegal things to make a living. Such as, robbing, stealing, even murdering. We can learn from the news that not a single day passes without the reports of somebody being kidnapped or being murdered. Walking alone at night makes people really nervous.
還有其他的問題：犯罪率。隨著競爭的加劇，一些人找不到工作。因此他們干起了違法的事情。偷盜、搶劫，甚至殺人。每天都看新聞就會發現，沒有一天新聞不報道有人被綁架被殺害的。獨自一個走在夜里讓人們緊張害怕。

All these problems make cities not as attractive as before. Some of them even move to the countryside. If we don’t fix these problems, the cities will break down sooner or later.
所以的這些問題讓城市不再像之前那樣吸引人了。一些人甚至搬到了郊外。如果我們不解決這些問題，城市遲早會分解的。
