Eat nuts, live longer. 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 well-being 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.

We humans love to scare ourselves. Newspapers and TV news are full of shock-horror stories about the killer flu virus(流感病毒)but are there things we can do to cut our risk of catching it?
Every year, people in Britain catch the flu virus and some of those who are already ill, or are very young, may die. It is very sad, but modern treatment means that many deaths can be avoided.
Experts tell us that the world is another flu epidemic(流行)and that the latest bird-flu virus would be the most likely cause. Humans can catch the disease only after closely contacting with a sick bird. However, if someone who had normal flu was to come into contact with bird flu, this could be very dangerous. The bird flu virus could attach(附在)itself to the human flu virus, mutate and then start to spread from person to person.
Coughs and sneezes(打喷嚏)always have spread diseases, especially colds and flu, and they still do. If bird flu does begin to infect humans, it will spread through coughs and sneezes.
If you want to stay free of flu and someone coughs or sneezes at you, what should you do?
First, keep your hands away from your face and wash them and your face as soon as you can. If a cough or a sneeze spray misses your face and you accidentally touch a droplet with your hands and then touch your face, the flu or cold bug could creep into your system.
小题1:The chances of most people catching bird flu are very small because __________. | A．they are strong enough to resist the infection | | B．only after closely contacting a sick bird can they be infected | | C．bird flu does not happen very often in the world | | D．only those who are ill can be infected |
小题2:In the passage the underlined word “mutate” probably means“__________”. | A．differ | B．produce | C．increase | D．change |
小题3:If a man with common flu is infected with bird flu, __________. | A．there must be no cure for him | | B．the disease will spread among humans | | C．he must feel cold | | D．he is likely to die |
小题4:Which of the following statements is true according to the passage?| A．Bird flu is the most dangerous disease. | | B．Normal flu can be easily changed into Bird flu. | | C．We don’t need to worry about flu virus. | | D．The person who has normal flu and comes into contact with bird flu can easily get Bird flu. |
小题5:The last paragraph of the passage tells us __________. | A．the reason why people with flu often cough | | B．coughs and sneezes are very dangerous | | C．how to protect ourselves from being infected | | D．how to avoid coughs and sneezes |

Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.
At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精炼米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins (维生素). The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.
Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don’t, they can also take vitamin pills.
小题1:The underlined word “cure” in Paragraph 1 probably means ______.| A．a medical treatment | B．a kind of vitamin | C．a kind of germ | D．a kind of rice |

小题4:If a person doesn’t get enough vitamins in his diet, he’d better ______.| A．eat more rice | B．eat more meat | C．eat some chicken | D．eat vitamin pills |
小题5:We can learn from the passage that ______.| A．beri-beri was caused by chickens | | B．the Javanese didn’t like vitamins | | C．Christian Eijkman’s experiment was successful | | D．the Javanese’s disease was caused by a kind of germ |

Imagine you are doing this reading in this text on the computer; what else are you doing? Maybe you’re eating a sandwich or drinking a cup of Starbucks. Should you eat while reading?
There aren’t many believable numbers, but we do know the number of people who eat while sitting in front of some type of screen is growing. A recent study found that 33 percent of families always have the TV on during meal times and another 27 percent people have it on at least half the time. Another 10 percent may be texting, emailing or talking on a cell phone while eating.
Any type of these behaviors is bad, considering the following evidence:
A Canadian study found that children who watch more than three hours of cartoons a day are 50 percent more likely to be fat than children who watch fewer than two hours. The researchers concluded that more than 60 percent of overweight incidents can be connected with screen watching too much.
A three-week study found that adults who usually play with smartphones less burned 119 more calories per day.
One Chicago researcher found that people eat more potato chips while reading online than when they have the laptop turned off.
There has been very little investigation(调查) into eating with your eyes staring at a screen or reading a book, but it is likely that his mindless eating is related to weight gain. Simply speaking, your brain has no idea what is going on with your mouth because it is occupied by other things. You don’t notice how full your stomach is, and you often don’t even notice the taste or the act of chewing and swallowing, as a result of which, developing an adapted dietary habit is a must.

Britons Learn to Forgive
LEEDS, England—A Leeds University psychology(心理学) professor is teaching a course to help dozens of Britons forgive their enemies.
“The hatred (仇恨) we hold within us is a cancer,” Professor Ken Hart said, adding that holding in anger can lead to problems such as high blood pressure and heart disease.
More than 70 people have become members in Hart’s first 20-week workshop in London—a course he says is the first of its kind in the world.
These are people who are sick and tired of living with a memory. They realize their bitterness is a poison they think they can pour out, but they end up drinking it themselves, said Canadian-born Hart.
The students meet in groups of eight to ten for a two-hour workshop with an adviser every fortnight.
The course ending in July, is expected to get rid of the cancer of hate in these people. “People have lots of negative attitudes towards forgiveness,” he said. “People confuse（混淆） forgiveness with forgetting. Forgiveness means changing from a negative attitude to a positive one.” Hart and his team have created instructions to provide the training needed.
“The main idea is to give you guidelines on how to look at various kinds of angers and how they affect you, and how to change your attitudes towards the person you are angry with, ”said Norman Claringbull, a senior expert on the forgiveness project.
Hart said he believes forgiveness is a skill that can be taught, as these people “want to get free of the past”.
