Imagine living locked inside a closet.You can’t choose when and what to eat or how you will spend your time.You can’t even decide when the lights go on and off. Think about spending your whole life like this.
This is the life of lab animals.
Now consider the needs of these animals.Chimpanzees(黑猩猩),in their natural homes,are never separated from their families.They spend hours together every day.But in a lab,chimpanzees are put in cages alone.There are no families,only cold,hard cages,and loneliness that goes on for so many years that most of them lose their minds at last.
Worse yet are the experiments.Animals are given diseases they would never normally get.Experimenters force-feed(给……强行喂食) chemicals to them,conduct repeated surgeries(手术),and much more,Think of what it would be like to put up with these and then be thrown back into a cage,usually without any painkillers.Often animals see other animals being killed right in front of them.
Hundreds of thousands of animals are poisoned,blinded,and killed every year in product tests for shampoos,skin creams and new cancer drugs.Although more than 500 companies have stopped testing on animals,some of them still force chemicals into monkeys’ stomachs and rabbits’ eyes.
Although some facilities are better than others at caring for animals—not every lab worker kills a mouse by cutting off its head with scissors—there are no happy animals inside laboratories.Will the lab life end? When will it end?The passage mainly tells us about .
| A．animals’ lives in laboratories | B．cruel experiments on animals |

Taking the train is a wonderful way to see America.In the 19th century,train routes appeared from coast to coast,carrying both people and goods Today,a long-distance Amtrak train trip is a different way to experience the United States.
The long-distance Amtrak trains have lots of room.Coach seats have lots of leg room and wide aisles(走
廊),sightseeing lounges(休闲室) have large windows,and sleeping areas can provide a good night’s rest.On a train trip,there’s time to talk,play cards or board games,and read to one another.On a car trip,parents have to drive while on a train,parents can sit back and watch the scenery go by.Unlike an a
irplane,traveling by train is not the quickest way to arrive at your destination;the train is the destination in itself.
Amtrak manages long-distance trains that run through the United States.Routes have different names,such as Empire Builder,California Zephyr,Sunset Limited and Southwest Chief.The long-distance trains have double-decker cars(Superliners), sightseeing lounges, and a real dining car.On shorter trains,such as from New York to Washington.DC,the cars are single level and only have a snack bar.In the Superliner trains,the sightseeing lounge is lined with windows on the second level while on the lower level a snack bar and tables can be found.In the evening,videos are shown in the lounge car—either entertaining movies or documentaries.
Tip:As delays are common on Amtrak trains,always call the station before you go there.Otherwise,you may be cooling your heels(脚后跟) for hours.What’s the advantage of seeing America by train?
| A．There are more services on the train than any other |
| B．Traveling by train is the quickest way to reach your destination. |

| D．The trains like Amtrak allow people to enjoy the journey cheaply. |
Which of the following can be found on short-distance Amtrak trains?
| A．Sleeping areas. | B．Snack bars. |
| C．Sightseeing lounges. | D．Coach seats. |
.What does the underlined sentence in the last paragraph mean?

As we all know sewing-machine(缝纫机) repair is one of the fastest growing businesses in the world today.Newspapers,women’s magazines,high schools and colleges are all encouraging millions of American women to do their own sewing,not only to make their
own shirts and sweaters,but also to make nice clothes for their husbands,sons,or boyfriends.The lates figures(数字) show that over 89 million American women,because of the high costs of ready-to-wear clothing are now making almost all of their families’ clothes.Most of these women 
get great satisfaction from making the family clothes on their own sewing machines.So it is natural that the demand(要求) for excellent service of sewing machines is growing.
Think of it! 89 million or more sewing machines,not including another 10 million sewing machines in schools of all kinds,need service at least once a year,and quite possibly four or more times each year.I know some women who return their sewing machines to repairmen time after time to get them fixed properly.I’ve seen sewing machines come out of repair shops in worse condition than they were when they went in.
So I’ve decided to write an introduction book to sewing-machine repair and teach people how to repair their own sewing machines at home.It’s not that difficult.In the book,I will teach you everything you need to know about how to repair your sewing machine.The author wrote the passage to .
| A．teach women to repair their sewing machines. |
| B．explain his or her purpose in writing the book |
| C．introduce the reasons for doing one’s own sewing |

| A．they cannot buy the clothes they see in magazines |
| B．their husbands or boyfriends want them to do so |
| C．ready-to-wear clothes cost a great deal of money |
| D．they can’t get great satisfaction from buying clothes |
We learn from the passage that sewing machines .
| A．aren’t very difficult to be repaired |
| B．cannot work well after one year |
| C．don’t easily get broken |
| D．need service 4 times a month |
It can be inferred from the passage that .

Alaskan black bears hibernate for up to seven months a year, during which time they do not eat or drink, before waking up in virtually the same physical state they fell asleep in．
Now experts hope to develop methods of putting humans into a similar state which could help astronauts survive long missions and lead to new ways of treating severely ill patients．
While many studies have examined hibernation in mice and hedgehogs, little research has been done into the same condition in larger mammals such as bears．
But new research conducted at the Institute of Arctic Biology at the University of Alaska monitored the animals' body temperature, heart rate and muscle movements while they slept.
The research results showed that during a five-month hibernation the bears’ body temeratures varied between 30℃ and 36℃ in cycles that lasted between two and seven days—a pattern that was previously unknown in hibernating animals.
The research project leader said, "If our research could help by showing how to reduce metabolic(新陈代谢的) rates and oxygen demands in human tissues, one could possibly save severely ill patients. We simply need to know how to turn things on and off to take advantage of the different levels of hibernation."
Craig Heller, of Stanford University, who contributed to the study, added: "There has always been a thought that, if there is ever long-distance space travel, it would be good to be able to put people into a state of lower metabolism or a state of hibernation. That's almost science fiction but you can see the logical basis."We know from the text that .
A．during winter Alaskan black bears sleep for more than half a yea r |
| B．researchers have examined hibernation in humans |
| C．experts have got no results from their research |
| D．Craig Heller is a leader from the Institute of Arctic Biology |
The best topic of the text should be ．
．
| A．The Latest Research Results |
| B．New Methods of Putting Humans into Hibernation |
| C．Alaskan Black Bears Hibernate |
| D．Astronauts Could Hibernate Like Bears |
According to the text, we can infer that .
| A．many studies have examined hibernation in mice and bears as well |
| B．humans' body temperatures vary between 30℃ and 36℃ while they sleep |
| C．research into hibernation in animals may help deadly patients stay longer |
| D．scientists have already take advantage of the different levels of hibernation in space missions |

Four common bad habits combined—smoking, drinking too much, inactivity and poor diet—can age you by 12 years, sobering new research suggests.
The findings are from a study that tracked nearly 5,000 British adults for 20 years, and they highlight yet another reason to adopt a healthier lifestyle.
Overall, 300 people studied had all four unhealthy behaviors. Among them, 90 died during the study, or 30 percent. Among the 400 healthiest people with none of the four habits, 8 percent of them died.
The risky behaviors were: smoking tobacco; downing more than three alcoholic drinks per day for
men and more than two daily for women; getting less than two hours of physical activity per week; and eating fruits and vegetables fewer than three times daily.
These habits combined substantially increased the risk of death and made people who engaged in them seem 12 years older than people in the healthiest group, said lead researcher Elisabeth Kvaavik of the University of Oslo.
The healthiest group included never-smokers and those who had quit; teetotalers, women who had fewer than two drinks daily and men who had fewer than three; those who got at least two hours of physical activity weekly; and those who ate fruits and vegetables at least three times daily.
"You don't need to be extreme" to be in the healthy category, Kvaavik said. "These behaviors add up, so together it's quite good. It should be possible for most people to manage to do it."
The US government generally recommends at least 4 cups of fruits or vegetables daily for a
dults, depending on age and activity level, and about 2 hours of exercise weekly．What problem may you have, if you smoke often and eat few fruits and vegetables?
| A．You would have difficulty in walking． | B．You would feel tired, lack of energy． |
| C．You may look older than you really are． | D．You may face the risk of death of cancer． |
How many of the 400 healthiest people with none of the four habits died?
| A．32. | B．24． | C．56． | D．120． |
What does this text mainly talk about?
| A．Suggestions to smokers． | B．The results of four bad life habits． |
| C．The findings of a new research． | D．The recommends from the US government. |
It was a quiet village in which there was a military camp. It was far from the towns and cities and there were some high mountains around. Of course it was a good place for training the new soldiers. But it was difficult for the young men to go outside. Mr. White, an officer of forty, was strict with them and he hardly let them leave the camp.
Once Mr. White was ill in bed. He couldn’t work and a young officer, Mr. Hunt, began to train the new soldiers instead of him. He knew the young men well and let nine soldiers go to the nearest town to have a holiday. But night fell and none came back to the camp. He was worried about it and stood at the gate. It was five to twelve when Mr. Hunt decided to go to the town and see what was happening with the young men. He started the car quickly and set off. At that moment the nine soldiers came back. It seemed they were all drunk. Of course they found the officer was angry.
“I’m sorry, sir,” said the first soldier. “I left the town on time. But something was wrong with my bus on my way here. I had to buy a horse and made it run fast. Bad luck! It died and I had to run back.”
And the other seven soldiers said they were late for the same reasons. It was the last soldier’s turn. He said, “I’m sorry, sir. I got on a bus on time, but…”
Having heard this, the officer became even angrier and stopped him at once. He called out, “If you say something was wrong with your bus, I’ll punish you at once!”
“No, no, sir,” said the young man. “My bus was all right, but the dead horses were in its way!” The military camp was built in the village to _______.

In the United States, friendships can be close, constant, intense, genero
us and real, yet fade away in a short time if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while— then no more. If the same two people meet again by chance, even years later, they pick up the friendship where it left off and are delighted.
In the States, you can feel free to visit people’s homes, share their holidays, or enjoy their lives without fear that you are taking on a lasting obligation(义务). Do not h
esitate to accept hospitality（好客） because you can’t 
give it in return. No one will expect you to do so for they know you are far from home. Americans will enjoy welcoming you and be pleased if you accept their hospitality easily.
Once you arrive there, the welcome will be full and warm and real. Most visitors find themselves readily invited into many homes there. In some countries it is considered inhospitable to entertain at home, offering what is felt as only home—cooked food, not “ doing something for your guest”. It is felt that restaurant entertaining, shows more respect and welcome. Or for other different reasons, such as crowded space, language difficulties, or family custom, outsiders are not invited into homes.
In the United States, both methods are used, but it is often considered more friendly to invite a person to one’s home than to go to a public place, except in purely business relationships. So, if your host or hostess brings you home, do not feel that you are being shown inferior treatment.
Don’t feel neglected if you do not find flowers awaiting you in your hotel room, either. Flowers are very expensive there; hotel delivery is uncertain; arrival times are delayed, changed, or 
canceled —— so flowers are not customarily sent as a welcoming touch. Please do not feel unwanted! Outward signs vary in different lands; the inward welcome is what matters, and this will be real.In the United States, you will find friendships ______ if circumstances change.
| A．die suddenly | B．pass away |
| C．disappear gradually | D．last forever |
Americans _____ their foreign friends to make a return for their hospitality.
| A．ask | B．don’t expect | C．never allow | D．wish |
In some other countries, giving a dinner party at home is considered ______ than in a restaurant.
| A．less friendly | B．less hospitable | C．more natural | D．more popular |
According to the passage, which of the follow
ing is NOT true?
| A．Flowers are signs of outward welcome. |
| B．Flowers are expensive. |
| C．Flowers are available at all time. |
D．Flowers are not necessarily sen t to guests. |
Situated in the South West of England, between Exeter and Plymouth, Torquay is one of the most popular holiday resorts in Britain. It provides a variety of entertainment, sports of every kind and cultural facilities, all set in a position of outstanding natural beauty. Visitors can choose between luxury hotels by the sea, with private suites（套房），swimming pools and saunas, and comfortable but less expensive guest houses. There are camping sites, too, and hundreds of houses displaying“B & B”signs.
As well as a number of small quiet bays, which are ideal for beach barbecues away from the crowds, Torquay has large sandy beaches where you can buy refreshments（饮料）and hire deck chairs, boats and even beach huts. There are large areas of grassland overlooking the sea, and miles of winding cliff paths for walkers who just want to enjoy the scenery and what is often said to be the healthiest air in the country. For the sportsmen and women there are opportunities not only for golf, tennis, squash and bowls, but also for water-skiing, hang-gliding and deep-sea fishing.
After a day in the open air, there’s lots to do in the evenings, too. There are plenty of discos, the occasional opera or ballet, and summer variety shows in the seafront theatres. For the children, there is a beautiful model village with a complicated railway layout which is remarkably realistic-especially when the lights are all on at night.
Of course, there’s no need to spend your whole holidays in Torquay. Only a s
hort drive away is Dartmoor National Park, where you can walk for miles through dramatic, unspoiled countryside, or picnic by beautiful rivers and streams. Or, nearer to home, you can sail across Tor Bay to the lovely old fishing village of Brixham.

People in the United 
States honour their
parents with two special days: Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June.These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care.
These two days make us think about the changing roles of mothers and fathers. More mothers are now working outside home. More fathers must help with the children care.
These two special days are celebrated in many different ways. On Mother’s Day, people wear carnations. A red one symbolizes a living mother, while a black one shows the mother is dead. Many people attend religious services to honour parents. It is also a day when people whose parents are dead visit cemetery ( 墓地). On these days, families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.
Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is the thought that counts. Greeting card stores, florists, candy makers, bakeries, telephone companies and other stores do a lot of business during these holidays.Which of the following is NOT a reason for parents show love and respect for parents?
| A．Parents bring up children |
| B．Parents give love and care to children |

Dear Mom and Dad,
I'm afraid I have some very bad news for you. I have been very naughty and the school master is very angry with me. She is going to write to you. You must come and take me away from here. She does not want me in the school any longer. The trouble started last night when I was smoking a cigarette in bed. As I was smoking, I heard footsteps coming towards the room .I did not want a teacher to catch me smoking, so I threw the cigarette away. Unfortunately, the cigarette fell into the waste-paper basket. It caught fire.
There was a curtain near the waste-paper basket. It caught fire too. Soon the whole room was burning. The master phoned the fire brigade. The school is a long way from the town and before the fire brigade arrived, the whole school was on fire. The master said that the fire was all my fault and I must pay for the damage. She will send you a bill for about a million dollars.
I'm very sorry for this.

When it comes to eating out, we can't help thinking of big meals in the restaurants, which usually contain much more fat and less fibers. Whether it is a business meeting over lunch or a fast food meal with the kids, eating out is a part of our lives. We eat out to save a lot of time, like grabbing a bite at fast food restaurants, or we take dining out as a favorite way to relax and socialize with friends.
Eating out can be fun but many people still like eating at home more because it is healthier. When my dear wife does not prepare foods for me, I would rather cook some instant noodles and eat at home! However, we go out to eat once in a while for holidays or on special occasions.
More and more people want to make healthy food choices nowadays. Some are watching calories, while others want to keep their cholesterol(胆固醇)under control or eat less fat. Plan ahead and choose wisely, you will find foods that fit into your meal plan and make eating out both healthy and enjoyable.
Here are some pointers to remember that can help you make wise choices when eating out: go for balance, watch portion sizes and drink water or low-fat milk. Keep the ground rules of good nutrition in mind. Eat a variety of foods in moderate(适中的)amounts, limit the amount of fat you eat, and watch the amount of salt in food. If you develop the skills to make healthy choices now, your body will thank you later.
Eating out can be one of life's great pleasures. Make the right choices, ask for what you need, and balance your meals out with healthy meals at home. You can enjoy yourself and take good care of yourself at the same time. From the passage, we can infer that often eating out______________ .
| A．contributes to healthy bodies | B．maintains good relations with friends |
| C．is of disadvantage to health | D．saves time from cooking |

We produce 500 billion of plastic bags in a year worldwide and they are thrown away pollu
ting oceans, killing wildlife and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a solution.
The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has-discovered a way to make plastic bags degrade(降解) in as few as 3 months, a finding that won him first prize at the Canada Wide Science Fair, a ＄10,000 prize, a ＄20,000 scholarship, and a chance to revolutionize a major environmental issue.
Burd’s strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.
With this goal in mind, he grounded plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.
The inputs are cheap, maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.
“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” Said Daniel Burd.Daniel Burd won first prize at the Canada Wide Science Fair because .
