Article: People are overweight for many reasons, the most important one of which is that they eat the wrong foods, get the wrong types of calories per meal, and they also eat meals at the wrong time each day. Food is more powerful than any weight loss pill, because the food that you eat can either make you thin or fat. This is true because your body is like an engine, and it only needs certain foods at certain intervals each day. Low-calorie Diets Do Not Work The reason people cannot lose weight by starving themselves is that their metabolism will detect any major drop in calories and it will then adjust itself by burning fewer calories each day. That is the reason why you can eat 1,000 calories per day and not lose any weight, while your friends can eat 2, 500 calories per day and not gain any weight. Low-fat Diets Do Not Work Many people in today's society are buying mostly low- fat or non-fat food at the grocery store. Everybody knows how much fat is inside the food they buy. However, people are getting fatter than ever before by doing this. They are not losing weight by changing to this low-fat lifestyle. Losing weight has nothing to do with these things. One of the most important things you can do to control your weight is to eat the proper foods, such as fruit and vegetables, eat them at the right time, and exercise every day. If people make this a habit, they will lose weight.
Answer: They eat the wrong foods at the wrong time.

Article: NANJING -- Another human H7N9 case has been found in east China's Jiangsu Province, the provincial health department confirmed on January 31. The patient, a 75-year-old woman from the provincial capital of Nanjing, is in a critical condition. The case brings the number of infections in the province to eight this year. H7N9 has killed 19 in China this year, and the total number of human infections reached 96 on January 26, according to the Chinese Center for Disease Control and Prevention. With bird flu cases increasing on a daily basis, public concern over people-to-people transmission during Spring Festival is growing. Li Lanjuan, researcher at the Chinese Academy of Engineering and a specialist in H7N9 prevention, said so far there have not been any cases in which one person transmits the flu to another, and the latter transmits the virus to a third person. Her team has identified H7N9 virus mutations this year, but the _ are not large-scale. "Inter-human transmission is very unlikely," said Li, who added that the virus has not evolved to be extensively drug resistant. The National Health and Family Planning Commission said on Wednesday live poultry markets should close if any case of H7N9 avian flu is detected. The southern metropolis of Shenzhen has closed all live poultry markets until February 13 for a thorough cleaning. The city near Hong Kong has reported 14 human H7N9 cases since December 18. Live poultry trading has been halted in Hangzhou, Ningbo and Jinhua cities in Zhejiang, which reported the largest number of human H7N9 cases. China has stepped up research for an H7N9 vaccine in the face of the increasing threat from the virus. Beijing's Snovac Hotech Ltd.,which developed the A/H1N1 and H5N1 vaccines, said in a press release on Wednesday that it has completed preclinical studies of an H7N9 vaccine arid prepared several types for clinical testing. The company has submitted an application to the China Food and Drug Administration to start clinical trials.
Answer: It once developed the A/H1N1 and H5N1 vaccines.

Article: 2009 is the year of what? Yes, it's the year of the Ox. But do you know that 2009 is also the year of the telescope? This year the world celebrates the 400thanniversary of Galileo's observations of the universe through an astronomical telescope . In 1609, the Italian scientist first pointed a "Dutch perspective glass" at the night sky and made discoveries that changed mankind's conceptions of the universe. In honor of Galileo's discoveries, the United Nations and the International Astronomical Union have declared 2009 to be the International Year of Astronomy (IYA 2009). IYA 2009 is a yearlong celebration of astronomy. Its goal is to spread knowledge of astronomy's contributions to society and culture and to inspire more interest in astronomy and science, especially among young people. The theme of the celebration is "The Universe, Yours to Discover." One interesting aim of the IYA is to encourage more diversity in the field of astronomy and physics. IYA organizers hope that the yearlong celebration of astronomy will inspire more females and underrepresented minorities to pursue careers in science. An event that will help further that goal is 100 Hours of Astronomy (100 HA) that will fall on April. This event aims to have as many people as possible look through a telescope. From April 2ndto 5th, millions of people worldwide will peer through telescopes to catch their first glimpse of the universe, just as Galileo's did 400 years ago. Sidewalk astronomy events will give city-dwellers an excellent opportunity to see the moon, the planet Saturn, and other objects in position for early evening observations. Organizers hope that the activities of IYA will "promote a greater appreciation of the astronomy." So join the fun. Look through a telescope this year!
Answer: The celebrations in IYA 2009.
