Researchers have found that those who eat a handful of peanuts every day significantly decrease their risk of dying from all causes compared to those who do not eat nuts. A new study concludes that all types of nuts seem to be protective. Researcher Ying Bao is with the Department of Medicine at Brigham and Women's Hospital and Harvard University Medical School in Boston, Massachusetts. She and her colleagues looked at the impact of nut consumption by analyzing two huge studies that began in 1980 - the Nurses' Health Study, which tracks the of more than 76,000 women, and 42,000 men enrolled in the Health Professionals Follow-up Study. Among the questions asked at the beginning of the studies was, 'how frequently do you eat nuts?' The information was updated every two to four years. Bao says the participants were followed for three decades. "What we observed is that people who eat more nuts are less likely to die over the next 30 years," said Bao. "So, for example, if a person eat(s) nuts once per day, that person has a 20 percent lower risk of dying." Bao says eating a handful of nuts five or more times per week was associated with a 29 percent reduced risk of dying from heart disease and an 11 percent lower risk of cancer death. A serving size is 28 grams. Nuts contain nutrients, including high quality proteins, vitamins and minerals, all of which have anti-cancer effects and may help protect the heart. Bao says researchers are planning studies to find out how nuts are beneficial to human health. The study on the health benefits of nuts was funded by the International Tree Nut Council Research and Education Foundation. Question: About Bao's research, which statement is true? - She has done the research by herself. - Her research was based on two studies. - Her research lasted about three years. - People should eat all kinds of nuts every day.
Her research was based on two studies.

Article: There has been a dramatic increase in the number of natural disasters over the past few years,and it is assumed that global warming and climate change could cause even more disasters in the future.Some of the world's leading cities are facing disasters like floods and heat waves. prefix = st1 /London London's flood defenses are getting older.Since 1 982,the Thames Barrier has protected the city from the threat of flooding,but it was only designed to last until 2030 and close once every two or three years.About 26 years later the barrier now closes five or six times a year and according to Environment Agency predictions,by 2050 the barrier will be closed on almost every tide if the problem is not addressed. There are 26 underground stations,400 schools,1 6 hospitals,an airport and 80 billion worth of property in London's flood risk area, so large scale flooding would be disastrous. Paris Over a six week period in July and August 2003,more than 1 1,400---mainly elderly people--died in France from dehydration and extremely high body temperature in a deadly heat wave.Heat waves of similar intensity are expected every seven years by 2050,so what can be done to make sure such a disaster does not happen again? One solution is to have air-conditioners installed in elderly care homes.But this is considered a short-term solution,as the increase in demand for electricity also increases carbon emissions . InParisthe local authorities are encouraging architects to design new types of buildings such as the building"Flower Tower,"which uses a covering.of bamboo to act as a natural air-conditioner. Shanghai Shanghai is the fastest growing city on Earth.It has a population of 1 8 million and is only 4 meters above sea level.Sea levels are predicted to rise by 20 cm within the next century. An estimated 250,000 people move to Shanghai every year in search of work, placing extra demands on energy consumption.China relies heavily on coal--fired power stations,but these emissions increase...

Read the following article and select the best answer. Article: Xiangzi - Lucky, in English - is appropriately named. His owner Qiu Hong, a sports marketer,lets the dog enjoy two daily walks,a collection of imported American toys, $300 worth of monthly food and treats and his own sofa in her high-rise apartment. When Ms. Qiu feels bored, she takes Xiangzi out for a long run in her car. In a sense, Xiangzi is not just a dog, but a social phenomenon - and, perhaps, a marker of how quickly the Chinese nation is booming through its transformation from poor farmer to first-world citizen.Twenty years ago,there were hardly any dogs in Beijing, but now there're 900,000 registered dogs with countless thousands of others unlicensed. How this came to be is, in some ways, the story of modern China as well. "People used to be focused on improving their own lives, and they weren't really acquainted with raising dogs," said Ms. Qiu. "But with the improvement in the economy, people's outlooks have changed." Having a dog can be a way to relieve the stress in people's lives, but mostly Beijing dogs have, as in the West, become objects of affection - even devotion - by their owners. It's easy to find dog-treat stores, dog Web sites, dog social networks, dog swimming pools - even, for a time recently, a bring-your-dog cinema and a bring-your-dog bar on Beijing's downtown nightclub row. The doglike devotion of pet owners here seems to have softened the city government heart. In 1994, Beijing officials relaxed their no-dog policy to "severely restrict" dogs. In 2003,it was changed again to allow anyone to own a dog, but to limit city dogs to no more than 35 centimeters in height. And nowadays the restriction seems to be loosely carried out. As for sti-fried Pekingese - well, that dog,too, may have seen its day. A formal suggestion to ban the eating of dogs has been made by a law professor named Chang Jiwen, who considered himself "not so much a dog lover as a China lover". "With China developing so quickly, more people should know how to treat animals properly," he said in 3 telephone interview. Question: Which is NOT mentioned in the article? - China's economical development. - The psychological problems in modern society. - People's attitude to wards animals. - The problems caused by dog keeping.
