Another thing an astronaut has to learn about is eating in space.Food is weightless, just as men are.
Food for space has to be packed in special ways.Some of it goes into tubes that a man can squeeze into his mouth.Bite-sized cookies are packed in plastic.
There is a good reason for covering each bite.The plastic keeps pieces of food from traveling in the spaceship.On the earth very small pieces of food would simply fall to the floor.But gravity doesn’t pull them to the floor when they are out of the plastic in a spaceship.They move here and there and can get into a man’s eyes or into the spaceship’s instruments. If any of the instruments is blocked, the astronauts may have trouble getting safely home.
As astronauts travel on longer space trips, they must take time to sleep. An astronaut can fit himself to his seat with a kind of seat belt. Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat.But be careful he must put his hands under the belt when he goes to sleep.This is because he is really afraid that he might touch one of controls that isn’t supposed to be touched until later.

A.Because small pieces of food would fall down to the floor. |
B.Because weightless pieces of food might make trouble when they travel around. |
C.Because they haven’t enough food for longer trips. |

Everyone has got two personalities—the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you’re awake because you can control your behavior, but when you’re asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their position. The important position is the one that you go to sleep in.
If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don’t like to upset people, so you never express your real feelings. You’re quite shy and you aren’t very confident.
If you sleep on your stomach, you are a rather secretive(不坦率的) person. You worry a lot and you’re always easily upset. You’re very stubborn(顽固的), but you aren’t very ambitious. You’re usually live for today not for tomorrow. This means that you enjoy having a good time.
If you sleep curled up (卷曲), you are probably a very nervous person. You have a low opinion of yourself and so you’re often defensive. You’re shy and you don’t normally like meeting people. You prefer to be on your own. You’re easily hurt.
If you sleep on your side, you have usually got a well-balanced personality. You know your strengths and weaknesses. You’re usually careful. You have a confident personality. You sometimes feel anxious, but you don’t often get depressed. You always say what you think even if it annoys people.

With the Tesla Roadster and other plugin (插入式) electric vehicles hitting the road,demand is growing for accessible refueling points to recharge(充电) them. Carbon Day Automotive, a Chicagobased company,has now demonstrated(演示)a solarpowered recharging point, known as the Solar PlugIn Station,which lets motorists easily charge their cars using electricity that has been produced without any environmental damage.
The Solar PlugIn Station has gone on show in Chicago as part of the city’s bid(竞标)to host the 2016 Olympic Games. According to Carbon Day Automotive,the Solar PlugIn Station on show in Chicago is part of the vital infrastructure(基础设施) required for electric vehicles in Chicago and was the focus of a recent visit by the International Olympic Committee.
These solarpowered electricity points will be used daily to fuel the city’s electric vehicles with power from the sun. By producing the electricity from pollutionfree solar cell, the CO2 emissions are reduced to zero.
“Solar energy and electric vehicles are a partnership that is one more step to reducing our dependence on foreign oil,” says Richard Lowenthal, CEO of Coulomb Technologies.Coulomb Technologies recently developed the components (部件) required for individual recharging stations,marketed as ChargePoint Networked Charging Stations.Carbon Day Automotive is the Midwest distributor for the ChargePoint stations. The Solar PlugIn Station consists of giant solar panels (电池板) that shade the tiny ChargePoint Networked Charging Station.The solar panel is connected to an underground battery pack,ready for everyday refueling.
“Without these stations it would be like driving around in a traditional car without the availability of gas stations,” says Scott Emalfarb,CEO at Carbon Day.“The day of true plugin electric vehicles will be here sooner than most people realize and the world needs to be ready to accommodate(为……提供场地)them.”

Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron there is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.
【小题1】Why did many people eat spinach after they saw Popeye the Sailor?
A.They thought spinach made them strong. |
B.They thought Popeye was funny. |
C.Spinach had a lot of iron. |
D.People liked folic acid. |
A.made Popeye strong |
B.was a green vegetable |
C.had less iron than other green vegetables |
D.had more iron than other green vegetables |
A.iron | B.folic acid | C.spinach | D.exercise |

Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.
Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five. The findings showed that stress levels dropped sharply after people reached their fifties. Happiness was highest among the youngest adults and those in their early seventies. The people least likely to report feeling negative emotions were those in their seventies and eighties.
The findings appeared in the Proceedings of the National Academy of Sciences. Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
The researchers considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.
The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.
【小题1】What is the best title of the passage?
A.The older a person is, the more stressed he feels. |
B.The more lighthearted a person is, the happier he is. |
C.The older a person is, the more clever he grows. |
D.The older a person is, the happier he grows. |
A.only when people get older, will they feel happier |
B.older people usually have no worries in their life |
C.stress levels among the youngest are the highest of all |
D.older people are more likely to be thankful in life |
A.When people get older, they can’t remember bad experiences. |
B.When people get older, they have no young children to care about. |
C.When people get older, they learn to adjust their feelings. |
D.When people get older, they don’t care about their feelings. |
A.A Gallup organization. |
B.A popular science magazine. |
C.A university in New York. |
D.A research institution |
A.Advice to the young people on how to keep happy. |
B.Advice to the old people on how to live longer. |

In Greek mythology(神话), fire is a gift form God, stolen from Zeus(宙斯) by Prometheus and handed over to humans suffering from cold. What could be more natural than sitting around a beautiful fire on a winter night, at a campsite in the Berkshires?
Hard as it may be to believe, the fireplace—long considered a trophy(奖杯), particularly in a city like New York—is acquiring a social shame. Among those who desire to be environmentally responsible, it is joining the ranks of bottled water and big houses.
Sally Treadwell, a 51-year-old public relations executive in Boone, N.C., said nothing makes her happier than building a fire on a cold winter night. But most of the time she doesn’t, because she feels too guilty about the damage it may do to the environment. Every time she builds a fire, it causes “inner conflict,” she said. “It’s a guilty pleasure”.
“The smoke from a fire smells very nice,” said Diane Bailey, a senior scientist with the Natural Resources Defense Council in San Francisco. “But it can cause a lot of harm. The tiny particles(颗粒) can cause illness, and can cross into the bloodstream, causing heart attacks as well as worsening other conditions.”
Growing concerns about the air pollution and health problems caused by smoke from wood fires are urging a number of areas across the country to pass laws regulating them. Idaho offers a tax cut to people who replace uncertified(不合格的)wood stoves with “greener” ones; San Joaquin County in California forbids selling a home unless its wood stove is replaced with an E.P.A. certified one;and Palo Alto and other governments in California forbid wood-burning fireplaces in new construction.
Certainly, many think otherwise. In any case, most fireplaces are used far too infrequently to cause any real damage to the environment, said Stephen Sears, the vice president of the Brick Industry Association, voicing an opinion shared by some.
Perhaps not coincidentally, sales of wood-burning equipment dropped to 235,000 in 2009 from 800,000 in 1999, according to the Brick Industry Association. It also reports that approximately 35,000 fireplaces were installed in the United States in 2009, compared to 80,000 in 2005. Certainly those numbers reflect the economic slowdown, but the may also be affected by growing mixed feelings to wood fries.
【小题1】We can infer from the 2nd paragraph that ________.
A.big houses are not considered environmentally friendly |
B.bottle water is a good companion for a fire place |
C.a fireplace is viewed as a sign of success |
D.people in New York are laughed at for their tradition |
A.her love for the fireplace |
B.the damage to the environment |
C.the concern about her health |
D.her mixed emotion fro the fireplace |
A.uncertified fireplaces are forbidden in Idaho |
B.some people are against the woodfire controlling regulations |
C.only energy-efficient wood stoves can be used in the US |
D.all the people support measures taken to control the use of fireplaces |
A.To urge people to burn less wood |
B.To discuss wood-burning’s impact |

Some snakes eat other snakes, even poisonous ones. The poison does not do them any harm(伤害). Snakes can swallow(吞下) things that are bigger around than they themselves are. This is possible because the jawbones(腭骨) are loosely joined, and the mouth can stretch(伸展)to make room for a fat animal. The snake’s slim body stretches to make space for the animal when it is inside.
Many snakes eat birds’ eggs or frogs(青蛙). Others eat pests(害虫), mice and other animals that harm crops on farms. Because snakes do this valuable work, you should never kill one. It is too dangerous for you to kill a poisonous one. Leave that job to experts.
【小题1】 Which of the following groups of food is usually had by a snake?
A.Mice, crops, birds’ eggs. |
B.Pests, frogs, some animals, plants. |
C.Birds’ eggs, frogs, all animals, other snakes. |
D.Mice, frogs, pests, some animals, other snakes. |
A.it is poisonous |
B.it can do something useful for man |

A study shows that nearly ninety percent of teens report that they have tried alcohol. That’s an increase of 23 percent in just four years!
Each year, 1.1 billion cans of beer are drunk by students aged 15-19 years old. Beer is the most common alcoholic drink among teens—81 percent of the drinkers had tried it. Beer is followed by wine with 63 percent, hard liquor(烈酒) with 53 percent and wine coolers with 35 percent.
When the young people are asked why they drank, the most common answer is that drinking is “something to do”. If a teen’s parents drink alcohol, the teenager is more likely to start drinking at an early age. Also, tens see all of their friends drinking alcohol so they think it is the must-to-do thing. Peer pressure is probably the hardest thing teens have to deal with. What’s more, teens often drink alcohol because it makes them feel older and cooler.
Researchers asked 56,000 students about their drinking habits and grades, to see how drinking might affect their grades in school. The results seem to be clear. Students who got a C level or lower tend to use three times as much alcohol as those who got B’s or A’s.
Alcohol use can be deadly. About 8,100 young people are killed per year in alcohol-related accidents. Eight young people die per day as a result of a drunk-driving accident. Between 50 and 65 percent of all teen suicides (自杀) occur after the young people drink.
So you see, drinking the alcohol doesn’t always end up with a good time. The next time you try to push someone to drink or someone tries to push you to drink, please remember this. One drink can set the habit for life. Why not throw it away?
【小题1】The reasons for teens’ drinking alcohol are mentioned EXCEPT that _______________.
A.they think it is cool to drink alcohol |
B.their parents set a bad example to them |
C.alcohol can make them happier |
D.peer pressure plays an important role |
A.Drinking alcohol makes students stupid. |
B.Good students never try alcohol. |
C.Drinking habits have something to do with IQ. |
D.Students with poor grades tend to use more alcohol. |
A.show the bad effect of drinking alcohol |
B.show how many teenagers drink alcohol |
C.tell teenagers not to try alcohol |
D.tell the reasons why teenagers drink alcohol. |

WELLINGTON, September 19 (Xinhua) -- If your teenage son won't get out of bed in the morning, then take comfort from the fact that he might be sleeping his way to a healthier future, according to a new research from New Zealand.
Researchers in human nutrition at the University of Otago have found that teenage boys who sleep less have more body fat when compared to girls, for whom lack of sleep has no noticeable effect on their body fat ratios.
The study of 386 boys and 299 girls aged 15 to 18 found that average-sized 16-year-old boy weighing 69.5 kg and 176 cm tall, who slept for eight hours a day, had a waist size l.8 cm bigger and l.6 kg, or 9 percent, more body fat than the average-sized boy who slept 10 hours a day.
"The boys who slept eight hours a day would also have l.8 kg more lean (bone and muscle) mass compared to the boys who slept 10 hours, but that's only a 1.4-percent increase, compared to the 9- percent increase seen in body fat," said lead researcher from the Department of Human Nutrition, Dr. Paula Skidmore.
"Our results suggest that for older teenage boys, making sure that they get enough sleep may help to maintain a healthier body. It seems to be that, within reason, the more sleep the better for boys," Skidmore said in a statement Thursday.
"It was unexpected that we did not find the same result in girls, who may actually be more aware of their diet and more in tune with a healthier lifestyle."
The researchers ruled out the effects of food choice and number of screens, such as televisions, games and consoles, which the teenagers had in their bedrooms.
【小题1】What's the research really about?
A.Boys and girls. | B.Food and weight. | C.Sleep and health. | D.Screens and fat. |
A.Bigger waist and more fat in the body. |
B.An increase in weight and height. |
C.More concerned with their diet. |
D.A decrease in bone and muscle. |
A.girls usually sleep less and have healthier lifestyles than boys |
B.the researchers expected to see the same result in girls |
C.peoples' diet has a great effect on their health |
D.boys are usually lazier than girls |
A.Teachers. | B.Girls. | C.Parents. . | D.Boys. |
