Zach Linsky, 11, watches TV for 3 and a half hours a day and plays video games every other day. Zach, a sixth grader in Washington, D. C., is an American. But unlike many kids, he doesn’t have a TV, VCR, or computer in his bedroom. He only has a boom box (手提录音机).
The survey of 3,155 kids, aged 2 to 18, shows that they spend 5 hours and 29 minutes on average(平均的) a day using some types of media outside of school, including 2 hours and 46 minutes watching TV, 21 minutes on the computer, 20 minutes playing video games, and 8 minutes on the Internet. The good news: The total includes 44 minutes spent reading.
The survey also shows that those aged 2 to 7 spend 3 hours and 9 minutes watching TV every day and shows that 32 percent in that age group have TV sets in their rooms. Among those aged 8 to 18, 21 percent have computers in their rooms, 65 percent have TV sets, and 61 percent say their parents don’t stop them from watching TV. Nearly 1 in 4 say they watch more than 5 hours a day.
“Kids are living much more lonely lives than ever before,” says Kay S. Hytnowitz. “They just disappear into their rooms and spend all of their time with these media.”

People mountain people sea? Yes, this means too many people at a place. This is a photo taken in Shenzhen.
Shenzhen’s fast development has made it become China’s most crowded city! There are about 15 million people living on its 1,991 square kilometres. On average (平均) 7,500 people live on each square kilometre. It is 1,080 more than that in Hong Kong, and nearly 800 more than that in Guangzhou.
Besides, Shenzhen owns 2 million local vehicles (车辆), and about 300,000 vehicles from other places also run on the local roads every day. The total length of the city’s road is 6,041 kilometres. It means each person only owns 0.58 metres of road!
As a result, the city is facing serious environmental and resource (资源) problems. One of the problems is water shortage. The amount of fresh water for each person of the city is only 25% of the country’s average. What’s more, most of the water drunk by Shenzhen people comes from other areas.

It’s possible to do many simple tricks with numbers. Here is one trick, if you follow the instructions, you will find it’s really interesting.
First, write down your house number. For example, if your address is 73 Jin Shang Road, you would write down 73. After you write down your house address number, you double it. Then add 5 to this doubled number. For example, if your address is 73 and you double it, you will get 146. Then you add 5, you will get 151.
And then, multiply this number by 50. In our example here, you’ll get 7550. The next step is to add your age to this total. For example, if you’re 16 years old, you should add 16 to this total. In our example here, the result will be 7566.
After that, you have to add the number of days in a year, which is 365. In our example here, 365 added to 7566 is 7931.
The final step is this: Subtract 615 from the number that you have. Take away 615 from the total. In our example, 7931 minus 615 is 7316.
The result here—7316—is the trick. The first part of the number is the address and the last part of the number is the age of the person. That is, 73 is the address that we started with, and 16 is the age that we used.

Western China is a large and beautiful region. It includes one major city, Chongqing, six provinces, and five autonomous regions (自治区). The six provinces are Sichuan, Shanxi, Gansu, Yunnan, Qinghai, and Guizhou. The five autonomous regions are Tibet, Ningxia Hui, Xinjiang Uygur, Guangxi Zhuang, and Inner Mongolia. Among all these provinces and autonomous regions, Xinjiang is the largest region and Ningxia is the smallest region.
Western China has an area of 5,400,000 square kilometers. This is about 56% of the total area of the country. However, there are many mountains, highlands, and deserts, and there are fewer rivers and lakes than in the East. Only around 22% of the population (人口) of China lives in the West, so there are far more people living in the East than living there.
Western China has a lot of natural resources. It is rich in oil and gas and it has many different kinds of minerals (矿). Tourists like to visit the area. There are many famous museums, ancient palaces, tombs (坟墓), and caves (洞), such as the Dazu museum, Shanxi History Museum, the Potala Palace, the Dunhuang Caves, and many other beautiful places such as Yunnan Dali and Sichuan Jiuzhaigou Valley.
