China's first moon rover (月球车), Yutu, set off from the lander（登陆车） early on December 15, several hours after the Chang'e-3 probe (探测器) soft-landed on the moon surface.

The 140 kg six-wheeled rover touched the moon surface at 4:35 a.m., leaving deep lines on the loose moon land. This was recorded by the camera on the lander and the images were sent to the earth, according to the Beijing Aerospace Control Center. After that, the rover and lander will take photos of each other and start their own science explorations.

Earlier this morning, engineers made final checks of the environment of the landing area and the situation of the probe（探测仪）. Yutu, reached its solar panel (光板) and started to drive slowly to the moon at 3:10 a.m.. It took Yutu nearly a whole hour to complete the simple task.

Chang'e-3 landed at the Bay of Rainbows on the moon, at 9:11 p.m. on December 14, making China the third country in the world to carry out such a mission (执行此类任务) after the United States and Russia.

In old Chinese tales, Yutu was the white pet rabbit of Chang'e’s. The name for the rover was selected following an online survey that collected several million votes from people around the world.

The rover, 1.5 meters long with its two wings folded (折叠), 1 m in width and 1.1 m in height, is a perfect robot controlled by the command center from the earth. It will face challenges including temperature differences of more than 300℃ on the moon.

Yutu will do some research and look for natural resources (资源) for three months, while the lander will conduct an exploration at the landing place for one year. Then they will have a good rest on the moon and will not be used for a long time until China’s next probe visits the moon again.

请认真阅读下面短文，并根据短文内容回答问题。

Zhang Li lies in bed sadly. The 24-year-old young man lost his right leg because of a blood disease (血液病). The doctor said that his 10 years of smoking had caused the disease.

“I first smoked a cigarette when I was in Junior 3. It made me feel like a man and I thought it looked cool. Now I know I was really wrong,” said Zhang.

According to the 2008 China Tobacco Control report (中国烟草控制报告), 130 million young people who are under 18 years old have tried smoking. Fifteen million of them are addicted (上瘾的).

The report came out on May 31, World No-Smoking Day. It also found that nearly 68% of teenage smokers smoked their first cigarette before the age of 13. Those living in big cities started even earlier.

“Some tobacco companies try to make cigarettes cool and attractive. It’s just to make money,” said Yang Gonghuan, a doctor. In fact, smoking is one of the top killers in China. Each year 1 million people die from smoking-related (与吸烟有关的) diseases. Smoking causes illnesses like lung cancer and heart disease.

Doctors say that the younger a person starts smoking, the worse it will be. If a person starts smoking as a teenager, he or she may live twenty-two years less than non-smokers.
