In recent years, more and more young people have joined in the NEET group. They neither go to college or receive any training for future work and depend on their parents for a living. Most of us are aged from 16 to 30.
In my opinion, it is shameful for the young not to make their own responsibility for their own life. Parents get old, how if someday they can not provide anything? Beside, society may break without the involvement of young people. Be independent is the key to success. The young generation should never forget that.

They say that the real marathon begins at 35 kilometers — the rest is just a warm up. And sure enough, in 2009, at around the 36 kilometer point of the Beijing Marathon I experienced what runners call “hitting the wall”. I had been doing well until that point, but suddenly I felt a sharp pain in my leg. My pace slowed down dramatically and every brain cell in my head seemed to be screaming “stop!!!”
The last 5 kilometers were not fun; in fact, they were really hard work. Keeping motivated to run those last few kilometers was one of the hardest things I had ever done. But that is what makes running a marathon such a rewarding experience — if it were easy everyone would do it.
I have to admit it is sometimes not even easy to find the motivation to get out of bed, pull on your running shoes and head out into the morning to go for another run. These last two weeks of training for the Muztagata climb have been a little tough. I have been following my training plan for about three months but now I find that my original enthusiasm (热情) has all been used up. Day after day of going to the gym is beginning to wear me down and there still seems so much longer to keep this up. I have begun to doubt that I am actually making any progress or getting any fitter and even thought that I might be going backwards!
These are all very common experiences for people who are working towards challenging, longer term goals and I have learned to recognize these “highs” and “lows” in my energy and enthusiasm. Over the years I have learned a number of tricks that help me to deal with the days when my early motivation seems to have abandoned me for good.

Air pollution is one of the hottest topics at present because poor air quality is an important factor in both the incidence and cause of respiratory(呼吸道) diseases.
Zhong Nanshan, a deputy to the NPC and a member of the CAE, said recently when the concentration of PM2.5 rises by 10 micrograms per cubic meter, hospitalization may rise by as much as 3.1 percent. Meanwhile, when the concentration of PM2.5 rises from 25 mgs per cubic meter to 200, the average daily death rate may rise to 11 percent.
Zhi Xiuyi, a leading expert in lung cancer treatment and also vice-president of the CATS, said medical authorities used to focus on tobacco control as a primary means of preventing lung cancer. "But in fact, air pollution is no less harmful than smoking and our research team released a report earlier this year showing that the cancer rate in Beijing is closely related to industrialization," he said.
The report, conducted by the Beijing Institute of Cancer Research, shows that the number of cancer patients in China has increased markedly during the past ten years. Chaoyang District, the city's main area of industrialization, has the highest incidence of cancer, almost double that of Yanqing, an area on the outskirts of the city. About four out of 1000 Chaoyang residents have some form of the disease, with lung cancer at the top of the list.
"The risk of having cancer largely depends on the length of exposure and the concentration of noxious gases(有毒气体的浓度)," said Zhi. In response to the doubt whether seven years' exposure to poor air quality will almost result in cancer, Zhi said the time scale was taken from research overseas that suggested the rate of incidence generally peaked in the seventh year of exposure to a heavily polluted environment.

C. It is very important to prevent people from smoking.
D. People realize the importance of keeping healthy.
3.If there were 3,000,000 people in Chaoyang District, how many would have respiratory diseases?
A. 16000 B. 12000 C. 8000 D. 7500
4.What can you infer from the passage?
A. Industrialization has its weakness as well as strengths.
B. The average death rate rises with different ages and places.
C. The air in Beijing is much more polluted than that in the other cities.
D. The more heavily-polluted air you breathe in, the sooner you’ll have cancer.
