Snack time is a part of the day for children of all ages. But new research suggests that kids snacking in big groups could be at risk for obesity.
Scientists from American University looked at the eating behavior of 54 kids between the ages of 2 and 6. At snack time, the scientist watched the amount of food each child ate while they were in groups of either three or nine. According to the study, the more children there are in a group, the more likely they are to eat more. Those in the larger group ate nearly 30 percent more than those in the smaller group, and they actually ate faster.
Since this is the first such study in children, scientists are quick to point out the importance of encouraging healthy habits in kids as early as possible.
“If you know kids eat more in large groups, it seems perfect to use this information to keep snack groups small or use small tables,” says Dr. Jana Klauer, an expert in New York.
Smaller groups would allow for a quiet and more relaxing environment-a perfect chance to teach children about food, manners and how to know when they feel full. “This would have an effect on kids' eating,” adds Klauer. “They would slow down and eat less.”

For hundreds Of years, scientists have been trying to answer what things have an effect on people’s emotions (情感). How you feel is controlled by many things. Your emotions can be affected by your personality, by the actions of others and by events around you. Perhaps you don’t know your emotions can be influenced by the weather as well.
People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight makes us feel good. When sunlight hits our skins, our bodies produce a vitamin. Vitamins are natural chemicals (化学物质) which we all need to stay healthy. Sunlight helps our bodies produce vitamin D. Vitamin D helps our bodies make a special chemical. This special chemical affects our brains (大脑) and makes us feel happy. For example, there are long, dark winters of little sunlight in Sweden and Norway, so many people in these countries often feel sad. Without much sunlight, their bodies produce less vitamin D. Without enough vitamin D, their bodies make less of this special chemical which makes them feel good. To help the people in these countries feel better, special “sunrooms” with artificial (人造的) lights have been built. People can go there and get “sunlight” for an hour or two!
The weather can also affect people’s emotions in other ways. Hot weather can make people angry because people feel uncomfortable when they are hot. In the same way, rain can make people angry because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals which control our brains. Through these ways, the weather can influence our emotions. Sadly, while the weather can change us, we can hardly change the weather.
【小题1】 Which of the following is NOT mentioned as a factor (因素) that can affect one’s emotions?

A ban on smoking in most public places goes into effect(效果) on Sunday in China - home to a third of the world's smokers. That means around 300 million smokers will no longer be allowed to light their cigarettes in the "enclosed public places." These include hotels, restaurants, theaters and public transport waiting rooms. The ban does not cover offices or factories.
The campaign is aimed at controlling(控制) the number of deaths from smoking-related illnesses, running at a million a year. According to the World Health Organization, more than 3,000 people die every day in China because of smoking. Health experts also hope it will help Chinese to raise the knowledge of the dangers of smoking.
But the new rules have been criticized because they do not include punishments(处罚) for those who choose not to obey them.Most people worry that Chinese smoking ban may have little effect.
Business owners often hate rules that force(强迫) them to ban smoking on their restaurants, bar, cafe..., because many customers(顾客) do not like the rules and complain. Often you find people smoking at the next table while you are eating your meal or having a drink in a bar.
It appears that many Chinese people don’t know the dangers of smoking. Research suggests only one in four knows the harm(害处) cigarettes or second-hand smoke can cause.
At the same time the government makes a lot of money from the sales of cigarettes by the state-owned firms that make and sell all tobacco products throughout the country.
