Have you ever dreamed of visiting a planet in the Milky Way (银河系)? While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut eye. They would have to sleep for years.

European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.

What seems like a science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don’t age. They have now moved on to the small, non-hibernating mammals (哺乳动物) like rats.

A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex (复杂的). "It’s like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy’s University of Pavia．Just like bears and frogs, the hibernation of human beings would cause a person’s metabolism (新陈代谢) to lower so they would need less energy.

Medical research, however, is just half of a space flight hibernation system. There is a challenge of designing a suitable protective shelter (栖身所). Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (监控) life functions and serve the physiological needs of the hibernator.

According to Ayre, the six-person Human Outer Planets Exploration Mission (使命) to Jupiter’s moon (木星的卫星) Callisto could be an opportunity to use human hibernation. The mission aims to send six persons on a five-year flight to Callisto, where they will spend 30 days, in 2045.

According to the article, the hibernation research ______.

       A．is just an idea          B．is always a science fiction  

       C．has already finished successfully     D． has made some progress

In a hibernating state, a person needs ______.

第三部分：阅读理解（共20小题，每题2分，满分40分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
A
We bet that on cold wintry days, many of you love to stay in your warm home and, every now and then, come out into the kitchen for a snack. Unfortunately, plenty of creepy-crawly critters(爬行生物) like to do the same thing!
Winter is the time when bugs (虫子) invade your house without an invitation. The season can be tough for such creatures. In winter the air is cold, the ground is hard and many trees have no leaves. So bugs do what they have to do to survive.
Monarch butterflies head south to warmer climates. Ants crowd in deep underground colonies and eat food they have been storing all year. Many insects go into a deep sleep called diapause. There’re different kinds of diapause, but all are similar to hibernation, a time when bigger animals become inactive in the cold. Insects go into an inactive period, too, but it often isn’t when the temperature drops.
They rely on more dependable signals in the environment. For example, many insects can tell how much sunlight there’s each day. They use that to tell them when to shut down. Bugs are cold-blooded, meaning that their inside temperature is the same as the outside. They can’t move much when it gets below 40 degrees Fahrenheit. So they search for any warm place.
They’re looking for protection. These guys have been doing this for 300 million years, so they don’t really know they’re coming into your house. The home is a recent event in terms of their evolutionary behavior. They enter through tiny cracks or come in unnoticed on your clothes or shoes. Remember that they may be invading your homes for warmth and food, but they don’t care about humans.
56. What is the purpose of the first paragraph?
A. To point out that humans like to stay at home in winter.
B. To mean that humans and bugs have the same living habits.
C. To mean that bugs will invade the house for their winter.
D. To put forward the idea that bugs are not welcome in winter.
57. According to the text, what is diapause?
A. It is the same as the animals’ hibernation.
B. It often appears in warm areas all the year.
C. It is done to keep bugs active in winter.
D. It is a deep sleep similar to hibernation.
58. What often decides bugs’ diapause?
A. The lower local temperatures.           B. The amounts of sunlight.
C. Kinds of environmental signals.         D. The insects’ inside temperature.
59. According to the text, bugs invade humans’ homes to ______.
A. attack humans                                 B. look for enough food
C. seek for protection                           D. show their evolutionary results
60. What would be the best title for the text?
A. Bugs’ life on cold wintry days
B. Why bugs invade your home in winter?
C. Good relations between humans and bugs
D. What does diapause mean?

Have you winterized your horse yet? Even though global warming may have made our climate more mild, many animals are still hibernating(冬眠)．It’s too bad that humans can’t hibernate．In fact, as a species, we almost did．

Apparently, at times in the past, peasants in France liked a semi-state of human hibernation．So writes Graham Robb, a British scholar who has studied the sleeping habits of the French peasants．As soon as the weather turned cold people all over France shut themselves away and practiced the forgotten art of doing nothing at all for months on end．

In line with this, Jeff Warren, a producer at CBC Radio’s The Current, tells us that the way we sleep has changed fundamentally since the invention of artificial(人造的) lighting and the electric bulb．

When historians began studying texts of the Middle Ages, they noticed something referred to as “first sleep”, which was not clarified, though．Now scientists are telling us our ancestors most likely slept in separate periods．The business of eight hours’ uninterrupted sleep is a modern invention．

In the past, without the artificial light of the city to bathe in, humans went to sleep when it became dark and then woke themselves around midnight．The late night period was known as ”The Watch” It was when people actually kept watch against wild animals, although many of them simply moved around or visited family and neighbours ．

According to some sleep researchers, a short period of insomnia(失眠) at midnight is not a disorder ．It is normal．Humans can experience another state of consciousness around their sleeping, which occurs in the brief period before we fall asleep or wake ourselves in the morning．This period can be an extraordinarily creative time for some people．The impressive inventor, Thomas Edison, used this state to hit upon many of his new ideas．

Playing with your sleep rhythms can be adventurous, as anxiety may set in．Medical science doesn’t help much in this case．It offers us medicines for a full night’s continuous sleep, which sounds natural; however, according to Warren’s theory, it is really the opposite of what we need．

1.The example of the French peasants shows the fact that________．

 A．people might become lazy as a result of too much sleep

 B．there were signs of hibernation in human sleeping habits

C．people tended to sleep more peacefully in cold weather

D．winter was a season for people to sleep for months on end

2.The late night was called “The Watch” because it was a time for people_______．

 A．to set traps to catch animals        B．to wake up their family and neighbours

 C．to remind others of the time       D．to guard against possible dangers

3.What does the author advise people to do?

 A．Sleep in the way animals do．    B．Consult a doctor if they can’t sleep．

 C．Follow their natural sleep rhythm．D．Keep to the eight-hour sleep pattern．

4.What is the author’s purpose in writing the passage?

A．To give a prescription for insomnia．   

B．To urge people to sleep less．

C．To analyze the sleep pattern of modern people．  

D．To throw new light on human sleep．

Some mammals migrate（迁徒）. One of these is the caribou（驯鹿）. They travel to the tundra（苔原）every summer to eat the rich grasses that grow there. When the weather becomes cooler, they migrate to the warmer forests and spend the winter there. Another mammal that migrates is the humpback whale. They spend the winter in Hawaii, and the summer in the Arctic（北极的）waters. They travel to the Arctic to eat millions of small shrimp（虾）.

Anther habit that some animals have to survive the cold winter is called hibernation. Animals that hibernate, rest or sleep during the winter. While they are hibernating, their bodies use up the fat layer that they have put on by eating large amounts of food during the summer. Some animals that hibernate in the Arctic are small animals called lemmings（旅鼠）, squirrels（松鼠）and bears.

There are two habit adaptations that animals in the Arctic have all year round. These are called herding and pack life. Caribou are example of animals that live in herds. A herd is a group of animals that lives together for most, or all of their lives. A herd of caribou can have a thousand or more animals in it. They live in herds for protection. It is easier for caribou to protect themselves when they are together than it is when they are alone. This is because the meat-eaters hunt in packs.

A pack is a small group of animals that lives together. It is usually controlled by a head male and a female. All the members of the pack must obey them. Packs have a very definite social structure. Each animal in a pack has a different position, or importance. Animals in a pack are usually meat-eaters. They live together for protection and hunting purposes.

3. Caribou live in herds in order to         .

A. use up their fat layer        B. find food        C. protect themselves     D. hunt in packs

4. What do we know about pack life according to the last paragraph?

A. Animals in pack are usually grain-eaters.

B. All animals are in an equal position in a pack.

C. It is either controlled by a head mate or by a female.

D. Each animal has its own different role in a pack.
