Some people can stay up all night and still get work done the next day. I’m not one of them. After a night without enough sleep, I feel sleepy. I have trouble remembering things. And all I want to do is to go back to bed and sleep.

How do you feel after you’ve stayed up late to finish schoolwork? Or the day after a slumber party? Scientists now say that your answers to these questions may depend on your genes, which tell our bodies and brains what to do. People have about 40,000 genes, and each gene can have different forms.

A new research suggests that a gene called period3 affects how well you function without sleep. The discovery adds to older evidence that period3 helps determine whether you like to stay up late or get up early.

The period3 gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you.

Scientists studied 24 people who had to stay awake for 40 hours straight. Then. they took tests that measured how well they could remember lists of numbers.

Results showed that the people with the short form of period3 performed much better than those with the long form did. In both groups, people performed worst in the early morning. After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests took about 18 minutes to nod off(磕睡)

People with long period3 gene fell asleep in just 8 minutes. They also spent more time on deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form.

I think I must have the long form period3. What about you?

Everyone knows that eating too much junk food is not good to our health. Yet, what is it about junk food that is so completely irresistible(无可抗拒的)? For one thing, it’s everywhere. From chips in fast food restaurants to candy in supermarkets, junk food always seems available. Thankfully, science is now providing new clues to help us reduce snacking.

Make friends with dainty(讲究的) eaters.

　 Studies have found that people tend to increase or reduce the amount of food they eat depending on what their companions are taking in.

See happy movies… and always get the smaller bag of popcorn(爆米花).

　 According to some experts, people eat up to 29% more popcorn if they are watching a sad or serious movie, compared to when they are watching a comedy. Viewers consumed almost 200 calories more when snacking from a large bucket, as opposed to when given a medium-sized container.

Eat breakfast.

　 Nutritionists have gone back and forth（来来回回）about the question of how much to eat in the morning, but new studies suggest that consuming a good breakfast is a must. Surveys on long-term weight-loss show that two key factors in keeping weight down are eating breakfast and exercising.

Divide your food and conquer overeating.

　 Any kind of dividing your food into portions slows down your eating. Any kind of marker makes you aware of what you’re eating and of portion size. Researchers advise reallocating（再分配）snack foods into small plastic bags. It sounds simplistic, but it works.

　 A. Because it’s available here and there. B. It’s delicious from chips to candy.

　 C. It’s easily taken everywhere.　　　　 D. It’s easily bought in fast food restaurants.

65.Which of the following is TRUE according to the passage?

The Japanese government has launched(发起)a campaign encouraging people to go to bed and get up extra early in order to reduce household carbon dioxide emissions(二氧化碳排放).
The Morning Challenge campaign，put forward by the Environment Ministry, is based on the idea that swapping late night electricity for an extra hour of morning sunlight could greatly cut the nation’s carbon footprint．
A typical family can reduce its carbon dioxide footprint by 85 kg a year if everyone goes to bed and gets up one hour earlier，according to the campaign．The amount of carbon dioxide emissions potentially saved from going to bed an hour early was equal to 20 percent of annual emissions from household lights，“Many Japanese people waste electric power at night time，for example by watching TV until very late,”a ministry spokesman told The Daily Telegraph.“But going to bed early and getting up early can avoid wasting electrical power which causes carbon dioxide emissions.” The campaign also proposes that people take advantage of an extra hour of morning sunlight by improving their lifestyles in general by running, doing yoga and eating a nutritious breakfast.
It is the latest action dealing with climate change by the Japanese environment ministry，which is faced with the challenge of reducing carbon dioxide emissions by 25 percent from 1990 levels within the next decade．
It was the same government department that launched the Cool Business campaign five years ago, which encouraged workers to wear short—sleeved shirts and offices not to turn air conditioning lower than 28 degrees during the summer.
