New York（Reuters）--Foods that fill you up without packing a ton of calories can help in the battle of obesity（肥胖），results of a new study suggest．
In the study，obese women who reduced the “energy density” of their diet by cutting their intake of fats and adding more fruits and vegetables lost more weight over a 12-month period，and felt less hungry，than those who simply reduced their fat intake．
“Adding low calorie-dense foods into the diet is an effective way of lowering calories and reducing hunger when you are trying to lose weight，” Dr Julia A Ello-Martin said．
One of the reasons people don't stick to a weight-loss diet is hunger．Ello-Martin and her colleagues guessed that a diet that controls hunger by encouraging dieters-to fill up on low energy-density foods may improve adherence（坚持），as well as increase weight loss．
For the study，97 obese women were randomly assigned to a group that was advised to decrease their intake of fats or one that was told to decrease their fat intake and increase low energy-density foods，particularly fruits arid: vegetables．Twelve months later，weight had come off the women in both groups．The women in the fruit and vegetable group，however，lost 7.9kg，in comparison to 6.4kg among the others．
The women in the fruit and vegetable group also experienced less hunger than tile women who only reduced their fat intake，study findings show．
Although the study' lasted only one year，Ello-Martin guesses the dieters may be able to keep their weight loss and dietary changes over a longer period
“They are getting to eat foods that are helping them not feel hungry，” she said．“What's more，the study didn't have that hideous approach of having to count calories even day．”

Research shows that humans switch from selfish to unselfish behaviors when they are watched. Do you?
A picture of a set of eyes on a computer screen can cause a change in the way people act. Even images of eyes on a charity donation, collection box encourage people to be unselfish, because people put more money in a collection box that has a picture of eyes on it than they do when a flower symbol is on the box.

Biology in Germany and Bettina Rockenbach of the University of Berlin,
the authors of a new study, found that people act better when they are being
watched because they feel they will be rewarded for good behaviour.
Their report also referred to other research showing that this response of
behaving well when watched is somehow coded into humans and
people respond this way unconsciously, or without realising it.
It is not just humans that act unselfishly when they are being watched.
A fish called the grooming fish cleans other fish. When other fish are
around, it is gentler. When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning.
The researchers suggest that the best way to get people to behave in the correct way is to make them feel watched. This could be the reason for the success of a famous American army poster. On it was a picture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the picture was the caption ‘I Want You’. It encouraged hundreds of thousands of young American men to join the army during the Second World War to fight the Germans and Japanese.
1. According to the report, why does a person behave better when he feels he is being watched?
A. He does not want to be shamed by others.
B. He needs to show he is a good person.
C. He desires others to like him more.
D. He feels he will receive some social reward.
2. The underlined word ‘coded’ (paragraph 3) is closest in meaning to______.
A. hidden B. programmed C. forgotten D. leaned
3. What is the text mainly about?
A. It describes changed behaviour when observed.
B. It details ways to control people's behaviour.
C. It tells how to make people work harder.
D. It discusses different advertising methods.
4. According to the text, which of the following statements is True?
A. People pretend to behave better when they are watched.
B. Fish bite other fish in a fish tank when they are alone.
C. People donate more money when they feel they are watched.
D. Soldiers fought better during World War II because of a poster.
5. Where would the study described in the text most likely be found?
A. In a newspaper. B. In a scientific journal.
C. In an advertising magazine. D. In a science textbook.
Let's face it．No one drinks diet soda for the taste．People drink diet soda in the hope that it will help them lose weight or at least keep them from gaining it．Yet it seems to have exactly the opposite effect, according to a new study．
Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet soda．"What we saw was that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler．
The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly l0 years．
While the findings are surprising, they also offer some explanations．
Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet soda, they don't lose weight at all．"We weren't seeing weight loss necessarily, and that was confusing to us," said Rogers．
So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people think they can eat more if they drink diet soda, and so over-compensate for the missing calories．
A related study found some sweeteners （甜味剂） raised blood sugar levels in some mice．"Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky," said Helen P．Hazuda, professor at the University of Texas's school of medicine．"They may be free of calories, but not of consequences．"

Read the passage carefully．Then answer the questions or complete the statements in the fewest possible words.
Most people look forward to retirement as a time when they can finally take up activities that they never had the time or energy to pursue before．But some recent studies on people in their golden years are disturbing: they suggest that retirees are more likely to suffer from depression and possibly higher rates of other diseases such as heart disease and high blood pressure．That’s why a new study of French workers is welcome news.
Led by Hugo Westland, a professor of psychology at Stockholm University, the study of more than 14,000 workers found lower rates of depression and fatigue (疲劳) in people after they got tired while they were still employed.
The scientists followed the employees of the French national gas and electric company for 14 years．They found in the year immediately after retirement, the volunteers reported 40% fewer depressive symptoms than they had in the year before their retirement．The researchers also found an 81% drop in reports of both mental and physical fatigue over the same time period.
Clearly, said Westerlund, much of these decrease in physical and mental fatigue can be traced back to relief from the stresses of work．The decline in depressive symptoms suggests that retirement may be having a positive mental effect, too, which may have a lot to do with the generous pensions (养老金) that French workers enjoy．Most retirees in that country still benefit from about 80% of their yearly salaries.
“The economic or financial situation in retirement is very important,” Westerlund says．“We don’t know if the decrease in fatigue and depressive symptoms is because of the removal of something bad while in work or the addition of something good while in retirement．But no matter the reason, if life in retirement is not comfortable, then we won’t see the improvements we did.”
However, in European nations like France, governments are considering changes to pension plans, which may affect retirees’ health after they leave their jobs－with less of a financial safety net, workers may no longer seem so mentally and physically happy to be out of work．
(Note: Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS.)
According to some recent studies, retired people may have depression and higher rates of other diseases like __________.
Westerlund’s group found that in the year just after the retirement most retired French workers felt much less tired both __________.

Teachers and parents usually call attention to the pictures when they read storybooks to pre-school children. But a new study suggests that calling attention to the words and letters on the page may lead to better readers.
The two-year study compared children who were read in this way in class with children who were not. Those whose teachers most often discussed the print showed clearly higher skills in reading, spelling and understanding. These results were found one year and even two years later.
Shayne Piasta, an assistant professor of teaching and learning at Ohio State University, was an author of the study. She says most pre-school teachers would find this method manageable and would need only a small change in the way they teach. They already read story-books in class. The only difference would be increased attention to the printed text. “If you get children to pay attention to letters and words, it makes sense that they will do better at word recognition and spelling.” But she says research suggests that very few parents and teachers do this in a systematic way.
More than 300 children aged four and five were observed in classrooms. They came from poor families and were below average in their language skills. For thirty weeks, the children took part in a program called Project STAR--- Sit Together and Read. The project is based at Ohio State. It tests the short-term and long-term results of reading regularly to pre-school children in their classrooms.
There are different ways that adults can talk to children about print. They can point to a letter and discuss it, and even trace the shape with a finger. They can point out a word and discuss the meaning of the print or how the words tell the story. And they can talk about the organization of the print--- for instance, showing how words are written left to right in English.
