Article: Do you find getting up in the morning so difficult that it's painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle. During the hours when you labour through your work, you may say that you're "hot". That's true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people that peak comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues as "Get up , John ! You'll be late for work again !" The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has. You can't change your energy cycle, but you can make your life fit it better. Habit can help. Dr. Kleitman believes. Maybe you're sleepy in the evening but feel you must stay up late anyway. Counteract your cycle to some extent by habitually staying up later than you want to . If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won't change your cycle , but you'll get up steam and work better at your low point . Get off to a slow start which saves your energy. Get up with a yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy for your sharper hours . Question: What's the best title of the passage? Yes or no, is the answer "Daily Energy Cycle"?
No

Article: A purple tomato genetically engineered to contain nutrients more commonly seen in dark berries helped cancer in mice, British researchers said on Sunday. The finding, published in the journal Nature Biotechnology, the idea that plants can be genetically modified(changed) to make people healthier. Cancer-prone mice fed the modified fruit lived significantly longer than animals fed a standard diet with and without regular tomatoes, Cathie Martin and colleagues at the government-funded John Innes Center in Britain reported. "The effect was much bigger than we had expected." said Martin, a plant biologist. The study focused on anthocyanins,a type of antioxidant found in berries such as blackberries and blackcurrants that have been shown to lower risk of cancer, heart diseases and some neurological diseases. While an easy way to improve health, many people don't eat enough of these fruits, the researchers said. Using genes from the snapdragon flower, the researchers discovered they could get the tomatoes to make anthocyanins---- turning the tomato purple in the process. Mice genetically engineered to develop cancer lived an average of 182 days when they were fed the purple tomatoes, compared to 142 days for animals on the standard diet. "It is greatly encouraging to believe that by changing diet, or specific components in the diet. You can improve health in animals and possibly humans." Martin said in a telephone interview. The researchers warned that trials in humans are a long way off and the next step is to investigate( look into) how the antioxidants actually affect the tumors to promote better health. But the findings do support the formal research suggesting that people can significantly improve their health by making simple changes to the daily diet, other researchers said. "It's exciting to see new techniques that could potentially make healthy foods even better for us." said Doctor Lara Bennett, science information office at Cancer Research UK. " But it is too early to say whether anthocyanins obtained... Question: According to Dr. Lara Bennett, the effects of anthocyanins through diet on human being _ Yes or no, is the answer "are not certain now."?
No

Article: Weeks have passed since the world lost contact with Malaysia Airlines flightMH370and its 239passengers and crew. Although there is little hope of finding any of the passengers and crew alive,China has been making all-out efforts to find what remains of the plane in the southern Indian Ocean,where the plane is believed to have crashed.The search operations involve the navy,the marine police,scientific research and so on.While China's authorities and military forces have passed the test,the search operations have also shown some weaknesses.It is necessary to address these problems because China is a nation that faces many natural disasters. Lack of professional equipment has been the most notable problem.Among all the ships involved in the search for MH370,only Nanhai jiu 115and Donghai jiu 101and a few other ships have professional rescue equipment.There are also gaps between China and the US in other technologies such as sea-probing equipment and telecommunications.China mainly sent transporter planes,which lacked the necessary equipment to probe the ocean.While the United States sent P-3C and P-SA planes and MH60-R helicopters with equipment that can probe to depths of 76meters and cover 770sq kilometers in four hours. China's technology clearly needs to be improved,After the plane lost contact on March 8,more than one satellite received signals from it,but there is no report of any of China's satellites receiving a signal. Besides technology,China urgently needs to strengthen its international soft power,because almost all the important information was first obtained by Western media,which put pressure upon the Malaysian government for more timely and accurate information.Chinese media mainly forwarded the news broken by their Western colleagues. Last but not least,more attention should be paid to international cooperation.The search and rescue efforts could well have been a race against time to save lives,but limited by international laws and the absence of cooperation mechanisms,China and some other... Question: What is China's most urgent problem to be deal with in rescue work according to the passage? Yes or no, is the answer "Lack of professional equipment."?
Yes

Article: A Chinese space capsule carrying three crew members has returned to Earth following a 13-day mission . Images of the capsule landing in Inner Mongolia at 10:05 local time were shown live on television. The astronauts, including China's first woman in space, carried out a successful manual docking with the Tiangong-1 laboratory module. This is a key step towards China's goal of building a space station by 2020. Premier Wen Jiabao praised it as a "complete success". "This is another outstanding contribution by the Chinese people to humanity's efforts to explore and use space," Mr Wen said in Beijing. "It feels so good to stand on Earth, and it feels even better to be home," astronaut Liu Wang was quoted by national broadcaster CCTV as saying. "Tiangong-1, our home in space, was comfortable and pleasant. We're very proud of our nation, " female astronaut Liu Yang said. The crew of the Shenzhou-9 craft successfully carried out the country's manual docking operation earlier in the week. The delicate procedure, which involved bringing together two orbiting objects travelling at thousands of miles an hour, was mastered by USSR and US space teams in the 1960s. The crew also carried out automatic docking of the two crafts in the process. The three astronauts returned to the Shenzhou-9 spacecraft on Thursday and performed a manual separation from the space laboratory. They touched down in Inner Mongolia's Siziwang county on Friday, with the capsule equipped with a parachute to slow its approach. Ms Liu, 33, is a major in China's air force from the central province of Henan. On China's Tencent QQ messaging service, she goes by the name "little Flying knight". She was selected into China's space programme only two years ago, but she did particularly well, the official news agency Xinhua says. The Shenzhou-9 spacecraft was launched on 16 June.
