Which of these world capitals is located the farthest north?

下列哪个国家的首都位于最北边?

Washington, D.C., Athens, Greece, Beijing, China, or Tokyo, Japan?

美国的华盛顿,希腊的雅典,中国北京还是日本东京?

Of these options, Beijing edges out the other capitals at a latitude of almost 40 degrees north.

在以上选项中,北京位于北纬40度,胜出。

AZUZ: And while the Chinese capital has grown to become an industrial powerhouse, it`s struggled with the side effect of that -- air pollution.

尽管北京已经成为一个工业城市,但是也面临着负面影响——空气污染。

Dangerous smog is a visible problem in and around Beijing.

雾霾是北京及其周边地区的一个显而易见的问题。

A few years ago, the communist nation declared a war on pollution. It has occasionally banned high polluting cars and trucks from driving. It`s put a hold on winter construction projects to try to improve air quality.

几年前,中国宣布治理污染。不时禁止高污染轿车和卡车。这是为了改善空气质量而举行的冬季项目。

Winter is usually the time of highest pollution because the country burns coal to keep heaters powered up. The country set a goal for Beijing and the cities around it to reduce air pollutants by 25 percent by the year`s end.

冬季通常是污染最严重的时期,因为燃煤供暖。中国为北京和周边城市设定了目标,在年底前将空气污染物减少25%。

But the measures to help air quality have hurt the economy. Businesses like glass factories have lost sales as they`ve had to upgrade to cleaner equipment. China`s annual economic growth was more than 10 percent in 2010. It`s now below 7 percent. At times, the government has relaxed the rules to protect jobs.

但是提高空气质量的措施已经损害了经济。玻璃工厂等企业业绩下降,因为它们必须将清洁设备升级。中国的年经济增长率,与2010年相比增长10%。但是现在有所下降,中国政府放松限制以改善就业。

Analysts say it`s trying to find the balance between keeping the economy growing while keeping pollutants from growing. There`s a growing number of tools that can help.

分析人士说,试图在保持经济增长和防止污染物增长平衡,有越来越多的工具可以提供帮助。

SUBTITLE: China`s smog-eating tower.

中国的雾霾塔

This is the largest smog vacuum cleaner in the world.

这是世界上最大的雾霾真空吸尘器。

Using positive ionization, it sucks up harmful airborne pollution articles. Then releases the newly-purified air.

利用阳离子化学反应,它吸入有害的空气污染物品,然后释放出净化的空气。

It can clean 30,000 m3 of air per hour. That`s one football stadium per day.

它每小时可以清洁3万立方米的空气,每天清洁的面积相当于一个足球场。

The tower creates a "bubble" of clean air which is 40 percent to 70 percent cleaner than the rest of the city

这座塔创造了一个清洁空气的“保护障”,其释放的空气比城市其他地方的清洁空气的清洁度要高出40%到70%。
