Children brought up on healthy diets are more intelligent compared with their junk food eating partners, a new research suggests．
Kids fed a diet packed high in fats, sugars, and processed（加工） foods had lower IQs than those fed pasta（意大利面食）, salads and fruit, it was found．
The effect is so great that researchers from the University of Bristol said those children with a "healthier" diet may get an IQ improvement．
Scientists stressed good diet was essential in a child's early life as the brain grows at its fastest rate during the first three years of life．
This indicated head growth at this time is linked to intellectual ability and “it is possible that good nutrition（营养） during this period may encourage excellent brain growth” ．
Scientists tracked the long term health and happiness of around 14,000 children born in 1991 and 1992 as part of the West Country's Avon Longitudinal（纵向的）Study of Parents and Children（ ALSPAC）．
Parents were questioned about the types and frequency of the food and drink their children consumed when they were three, four, seven and eight and a half years old． According to their different changing form, these children were marked and given grades which ranged from minus two for the most healthy to10 for the most unhealthy．
In the research, IQ was measured of 4,000 children when they were eight and half years old, using a validated（经过认证的）test－the Wechsler Intelligence Scale（韦氏儿童智力量表） for Children．
The results found after taking account of some influential factors, a leading processed food diet at the age of three was associated with a lower IQ at the age of eight and a half , whether the diet was improved after that age．
Every l point increase in dietary pattern score was associated with a l.67 fall in IQ．

Decision-making under Stress
　　A new review based on a research shows that acute stress affects the way the brain considers the advantages and disadvantages, causing it to focus on pleasure and ignore the possible negative (负面的) consequences of a decision.
　　The research suggests that stress may change the way people make choices in predictable ways.
　　“Stress affects how people learn,” says Professor Mara Mather. “People learn better about positive than negative outcomes under stress.”
　　For example, two recent studies looked at how people learned to connect images(影像) with either rewards or punishments. In one experiment, some of the participants were first stressed by having to give a speech and do difficult math problems in front of an audience; in the other, some were stressed by having to keep their hands in ice water. In both cases, the stressed participants remembered the rewarded material more accurately and the punished material less accurately than those who hadn’t gone through the stress.
　　This phenomenon is likely not surprising to anyone who has tried to resist eating cookies or smoking a cigarette while under stress –at those moments, only the pleasure associated with such activities comes to mind. But the findings further suggest that stress may bring about a double effect. Not only are rewarding experiences remembered better, but negative consequences are also easily recalled.
　　The research also found that stress appears to affect decision-making differently in men and women. While both men and women tend to focus on rewards and less on consequences under stress, their responses to risk turn out to be different.
　　Men who had been stressed by the cold-water task tended to take more risks in the experiment while women responded in the opposite way. In stressful situations in which risk-taking can pay off big, men may tend to do better, when caution weighs more, however, women will win.
　　This tendency to slow down and become more cautious when decisions are risky might also help explain why women are less likely to become addicted than men: they may more often avoid making the risky choices that eventually harden into addiction.

A．keep rewards better in their memory

An Italian couple are to become the world's oldest divorcees, after the 99 - year – old husband found that his 96 - year - old wife had an affair（婚外情）in the 1940s．
The Italian man, called by lawyers in the case as Antonio C, was looking through an old drawer when he made the discovery a few days before Christmas．
In spite of the time that had passed since the affair, he was so upset that he immediately asked his wife of 77years, named as Rosa C, whether it was true, and demanded a divorce．
Stricken by the guilt, she reportedly admitted everything but was unable to persuade her husband to reconsider his decision, though her children also did much more work．
She wrote the letters to her lover during a secret affair in the 1940s, according to court papers released in Rome this week, which made people know the truth．

The discovery of the letters was the final problem for their marriage which had already run into difficulty－10 years ago the husband briefly left their house in Rome and moved in with one of his sons, only to return a few weeks later．
The Italian thought the fierce split resulted from the couple's southern blood 一 he is originally from Olbia in Sardinia: while his wife was born in Naples． The couple met during the 1930s when Antonio served as a young officer．
The case appears to set a new record, at least for the age of the oldest figures – the previous oldest couple to divorce were Bertie and Jessie Wood, both aged 98, from the UK．
That pair ended their 36 - year marriage in 2009 when they were both two years away from their l00th birthdays．They got married in Elstree, Hertfordshire, in 1972, having both ended previous marriages, before moving to Falmouth, Cornwall four years later．

Death Valley is a land of beautiful yet dangerous extremes. Death Valley can be dangerously cold during the winter months. Storms in the mountains can produce sudden flooding on the floor of the Valley.
The air temperature during the summer has been as high as fifty- seven degrees Celsius. The sun can heat the ground so that the temperature of the rocks and soil can be as high as seventy -four degrees Celsius.
Death Valley contains evidence of several ancient volcanoes that caused huge explosions. Evidence of one of these explosions is called Ubehebe Crater. The explosion left a huge hole in the ground almost a kilometer and a half wide. In many areas of Death Valley it is easy to see where the ground has been pushed up violently by movement deep in the Earth. This movement has created unusual and beautiful rock formations. Some are red. Others are dark brown, gray, yellow or black.
The area was named by a woman in 1849. Thousands of people from other parts of the ountry traveled Lo the gold mining areas in California. They were in a hurry to get there before other people did. One group trying to reach California decided to take a path called the Old Spanish Trail. By December they had reached Death Valley. They did not have to survive the terrible heat of summer, hut there was still an extreme lack of water. There were few plants for their work animals to eat.
The people could not find a pass through the call mountains to the west of the Valley. Slowly, they began co suffer from a lack of food. To survive, they killed their work animals for food and began to walk out of the Valley. As they left, one woman looked back and said, “Good -bye, death valley.” The name has never been changed.
Almost everyone who visits Death Valley visits a huge house called Scotty' s Castle. The building design is Spanish, with high thick walls to provide protection from the fierce heat.

When you get in your car, you reach for it. When you're at work, you take a break to have a moment alone with it. When you get into a lift, you play with it.
Cigarette? Cup of coffee? No, it's the third most addictive thing in modem life, the cell phone. And experts say it is becoming more difficult for many people to curb their longing to hug it more tightly than most of their personal relationships.
The costs are becoming more and more evident, and I don't mean just the monthly bill. Dr.Chris Knippers, a counselor at the Betty ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on -one personal contact, and an escape from reality. Sounds extreme, but we' ve all witnessed the evidence: The person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him. Jim Williams, an industrial sociologist based in Massachusetts, notes that cell - phone addiction is part of a set of symptoms in a widening gulf of personal separation. He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with. Despite the growing use of phones, e - mail and instant messaging, in other words, Williams says studies show that we don't have as many friends as our parents. “Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends,” he says.
If the cell phone has truly had these effects, it's because it has become very widespread. Consider that in 1987, there were only l million cell phones in use. Today, something like 300 million Americans carry them. They far outnumber wired phones in the United States.
