People who are outdoors in cold weather should avoid actions like suddenly lifting a heavy basket full of snow. Even walking through heavy, wet snow can strain a person’s heart.
Many people aren’t conditioned to the physical stress of outdoor activities and don’t know the dangers of being outdoors in cold weather. Those who like winter sports can suffer accidental hypothermia if they don’t make certain preparations.
Hypothermia means the body temperature has fallen below normal. It occurs when your body can’t produce enough energy to keep the internal (内部的) body temperature warm enough. It can kill you. Heart failure causes most deaths in hypothermia.
Children, the elderly and those with heart disease are at special risk. As people age, their ability to keep a normal internal body temperature often decreases. Elderly people can suffer hypothermia without knowing they’re in danger because they can’t notice the cold conditions as quickly as the young.
Besides cold temperatures, high winds, snow and rain can also steal body heat. Wind is especially dangerous because it removes the layer of heated air from around your body. At 30 degrees Fahrenheit in a 20-mile-per-hour wind, the cooling effect is equal to calm air at four degrees. Similarly dampness (湿气) causes the body to lose heat faster than it would at the same temperature in drier conditions.
To keep warm, wear more clothes. This traps air between layers. Also, wear a hat or head scarf. Much of your body’s heat can be lost through your head. Keep your hands and feet warm, too, as they tend to lose heat rapidly.
Don’t drink alcohol before going outdoors or when outside. Alcohol makes you feel warm at first because blood vessels in the skin expand. But heat is then drawn away from the body’s important organs.The underlined word “strain” in Paragraph 1 means ________.
| A．injure | B．warm | C．control | D．burn |

| A． they like exercising outside in cold mornings |
| B． they can’t notice cold conditions if they are not told |
| C． their body temperature is generally lower than young people’s |

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. 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 |
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 |
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. |
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. |
This brief book is aimed at high school students, but speaks to anyone learning at any stage of life.
Its formal, serious style closely matches its content, a school-masterly book on schooling. The author, W. H. Armstrong, starts with the basics: reading and writing. In his opinion, reading doesn’t just mean recognizing each word on the page; it means taking in the information, digesting it and incorporating it into oneself just as one digests a sandwich and makes it a part of him. The goal is to bring the information back to life, not just to treat it as dead facts on paper from dead trees. Reading and writing cannot be completely separated from each other; in fact, the aim of reading is to express the information you have got from the text. I’ve seen it again and again ：some-one who can’t express an idea after reading a text is just as ineffective as someone who hasn’t read it at all.
Only a third of the book remains after that discussion, which Armstrong devotes to specific tips for studying languages, math, science and history. He generally handles these topics thoroughly(透彻地) and equally, except for some weakness in the science and math sections and a bit too much passion(激情) regarding history to his students, that was a hundred times more than my history teachers ever got across. To my disappointment, in this part of the book he ignores the arts. As a matter of fact, they demand all the concentration and study that math and science do, though the study differs slightly in kind. Although it’s commonly believed that the arts can only be naturally acquired, actually, learning the arts is no more natural than learning French or mathematics.
My other comment is that the text aged. The first edition apparently dates to the 1960s—none of the references(参考文献)seem newer than the late 1950s. As a result, the discussion misses the entire computer age.
These are small points, though, and don’t affect the main discussion. I recommend it to any student and any teacher, including the self-taught student. According to Armstrong, the goal of reading is to________.
| A．gain knowledge and expand one’s view |
| B．understand the meaning between the lines |
| C．experts ideas based on what one has read |
| D．gets information and keeps it alive in memory |
The author of the passage insists that learning the arts_________.
| A．requires great efforts |
| B．demands real passion |
| C．is less natural than learning maths |
| D．is as natural as learning a language |
What is a shortcoming of Armstrong’s work according to the author?
| A．Some ideas are slightly contradictory. |
| B．There is too much discussion on studying science. |
| C．The style is too serious. |
| D．It lacks new information. |
This passage can be classified as________.
| A．an advertisement |
| B．a book review |
| C．a feature story |
| D．A news report |
They wear the latest fashions with the most up-to-date accessories (配饰). Yet these are girls in their teens or twenties but women in their sixties and seventies. A generation which would once only wear old-fashioned clothes is now favoring the same high street looks worn by those half their age.
Professor Julia Twigg, a social policy expert, said, “Women over 75 are now shopping for clothes more frequently than they did when they were young in the 1960s. In the 1960s buying a coat for a woman was a serious matter. It was an expensive item that they would purchase only every three or four years — now you can pick one up at the supermarket whenever you wish to. Fashion is a lot cheaper and people get tired of things more quickly. ”
Professor Twigg analyzed family expending（支出）data and found that while the percentage of spending on clothes and shoes by women had stayed around the same—and 5 or 6 per cent of spending—the amount of clothes bought had risen sharply.
The professor said, “Clothes are now 70 per cent cheaper than they were in the 1960s because of the huge expansion of production in the Far East. In the 1960s Leeds was the heart of the British fashion industry and that was where most of the clothes came from, but now almost all of our clothes are sourced elsewhere. Everyone is buying more clothes but in general we are not spending more money on them. ”
Fashion designer Angela Barnard, who runs her own fashion business in London, said older women were much more affected by celebrity(名流) style than in previous years.
She said, “When people see stars such as Judi Dench and Helen Mirren looking attractive and fashionable in their sixties, they want to follow them. Older women are much more aware of celebrities. There’s also the boom in TV programmes showing people how they can change their look, and many of my older customers do yoga to stay in shape well in their fifties. When I started my business a few years ago, my older customers tended to be very rich, but now they are what I would call ordinary women. My own mother is 61 and she wears the latest fashions in a way she would never have done ten years ago. ”Professor Twigg found that, compared with the 1960s, _______.
| A．the price of clothes has generally fallen by 70% |
| B．the spending on clothes has increased by 5% or 6% |
| C．people spend 30% less than they did on clothes |

For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?
Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course. the teens see it in exactly the same way, except oppositely. Both feel trapped
In this article. I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right, It doesn’t matter what the topic is –politics. The taws of physics, or the proper way to break an egg –the point of these arguments is to prove that you are right and the other person is wrong. for both wish to be considered an authority—someone who actually knows something —and therefore to command respect. Unfortunately, as long as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progressWhy does the author compare the parent-teen war to a border conflict?
| A．Both can continue for generations. |
| B．Both are about where to draw the line |

| B．Examples of the parent –teen war. |
| C．Solutions for the parent –teen problems |
| D．Future of the parent-teen relationship |
It was a Sunday and the heavy storm had lasted all night. The morning after the storm, though, was beautiful: blue skies, warm air and a calm, inviting sea touching the shore gently.
My father realized it was a good day for fishing and invited my sister and me to go with him. I was only 14 and fishing had never been my thing, but I decided to go all the same. I’m so glad I did.
On the road to the harbour we could see the terrible destruction on the coast, but the harbour itself was in fairly good shape. After all，it was protected by the arms of a bay that had only one tiny channel to the sea. As we got on board, we noticed two big humps(脊背) in the distance.
On approaching them, we saw it was a mother whale with her baby. We couldn’t believe it ——there aren’t any whales along the coast here. The storm must have driven them across the ocean into the bay, in which the still water was so badly polluted that nothing could survive.
The little baby whale——actually as big as our boat——was obviously stuck and could not move. The mother dived under the water and came up suddenly, making big whirlpools(漩涡) and waves. ”She’s trying to help her baby, but on the wrong side, ”my father said. At this point, my father moved our boat in a semicircle to the other side and, heading the boat towards the baby whale, pushed it gently. With our several gentle pushes the big hump turned over and disappeared under water. Then it swam up right beside its mum. They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction. We hurried up to the whales and tried to lead them towards the bay channel. Slowly, they let us lead them, some-times rising from the water right beside us to breathe——and to give us a trusting look with those huge eyes. Once they hit their first part of clean water flowing straight from the sea, the mum gave us a wave with her tail and off they swam into the distance.
In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for almost an hour and a half. That was the simple and lasting beauty of the day, Nearly four decades later, I still look back fondly to that golden day at sea.The author says “I’m so glad I did. ”(in Para. 2)because __________.
