Winter is dangerous for drivers because it is so difficult to know what is going to happen and accidents take place easily. Bad weather can be waiting to meet you. Ice might be hiding under the snow, waiting to send you off the road. The car coming towards you might suddenly move across the road. Here are two rules for driving safely on icy roads:

Rule Number One is to drive smoothly. Irregular movements can make a car very difficult to manage. So each time you turn the wheel, touch the brake or increase your speed, you must be as gently and slow as possible. Just imagine you are driving with a full cup of hot coffee on the seat next to you. You should drive carefully enough in order that you would not get the coffee out of the cup.

Rule Number Two is to pay attention to what might happen. The more ice there is, the farther you have to look down the road. Test how long it takes to stop by gently braking. Remember that you may be driving more quickly than you think. Generally speaking, allow double your normal stopping distance when the road is wet, three times this distance on snow, and even more on ice. Try to stay in control of your car at all times, or you will get into trouble.

Which of the following can be used to explain why driving in winter is very dangerous?

A. People drive more gently and slowly.

B. People drive three times faster than usual.

C. Unexpected things may often take place.

D. Drivers usually have too much coffee.

What is the main idea of Rule Number One?

A. To increase the driving speed.

B. To drive smoothly on icy roads.

C. To manage your car irregularly.

D. To drive fast on snowy roads.

Why does the writer want to take an example “a full cup of hot coffee” in Paragraph 2?

A. Because drinks are necessary for drivers.

B. Because he wants to remind drivers to take a rest.

C. To enjoy the driving with a cup of coffee.

D. To explain the importance of careful and smooth driving.

Which of the following is the best title for the passage?

A.Traffic Accidents. B. Careless Driving.

C. Bad Weather. D. Winter Driving.

Birds that are half-asleep—with one brain hemisphere (半球) alert and the other sleeping—control which side of the brain remains awake, according to a new study of sleeping ducks.

Earlier studies have documented half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere’s eye stays open and alert. Birds also can sleep with both hemispheres resting at once.

Decades of studies of bird groups led researchers to predict extra alertness in the end-of-the-row sleepers which tend to be attacked more easily. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction.

Also, birds napping at the end of the line depend on single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Turning 16 birds through the positions in a four-duck row, the researchers found that compared with 12 percent for birds in internal spots, outer birds half-asleep during some 32 percent of napping time.

“We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness at the same time in different regions of the brain,” the researchers say.

The results provide the best evidence for a long-standing assumption that single-hemisphere sleep evolved as creatures scanned for enemies. The preference for opening an eye on the lookout side could be widespread, he predicts. He’s seen it in a pair of birds napping side-by-side in the zoo and in a single pet bird sleeping by a mirror. The mirror-side eye closed as if the reflection were a companion and the other eye stayed open.

Useful as half-sleeping might be, it’s only been found in birds and such water animals as dolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning.

Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UCLA says he wonders if birds’ half-brain sleep “is just the tip of the iceberg.” He supposes that more examples may turn up when we take a closer look at other species.

According to the passage, birds often half sleep because ______.

A. they have to watch out for possible attacks

B. their brain hemispheres take turns to rest

C. the two halves of their brain are differently structured

D. they have to constantly keep an eye on their companions

What is implied about the example of a bird’s sleeping in front of a mirror?

A. An imagined companion gives the bird a sense of security.

B. Birds prefer to sleep in pairs for the sake of their security.

C. The phenomenon of birds napping in pairs is widespread.

D. A single pet bird enjoys seeing its own reflection in the mirror.

While sleeping, some water animals tend to keep half awake in order to ______.

A. alert themselves to the approaching enemy

B. emerge from water now and then to breathe

C. be sensitive to the ever-changing environment

D. avoid being swept away by rapid currents

By saying “just the tip of the iceberg”, Siegel suggests that ______.

A. half-brain sleep has something to do with icy weather

B. the mystery of half-brain sleep is close to being solved

C. most birds living in cold regions tend to be half sleepers

D. half-brain sleep may exist among other species

Today, over six billion people live on the planet. This means that there are very few places on Earth with no people. One place that has very few people is at the bottom of the Earth. In Antarctica, the icy continent surrounding the South Pole, you will not find anyone who lives there all the time.

First, Antarctica is the coldest place on Earth. For example, it can be –l30℃ in the winter. Humans cannot live in this kind of environment. Because it is so cold, very few plants or animals live there. This means there are no farms and no places to find wild plants or animals to eat.

Second, Antarctica can be dangerous. Many people think that it is safe to travel to Antarctica in the summer months when it is warmer. However, Antarctica is mostly ice, so when it’s summer, the ice melts. When the ice melts, the ice can break. So, people cannot travel around Antarctica during the summer. If the ice breaks, they could fall into the water and die.

Another serious problem in Antarctica is the sun. Because Antarctica is mostly ice, there are no trees so there is no shade. Also, the ground is mostly white ice so the sun bounces off (反射) it. The light from the sky and the light from the ground can burn people’s skin and hurt their eyes. People must be very careful in this situation. For example, they must wear sunglasses to protect their eyes. They must also cover their hands and faces all the time.

Although Antarctica is a tough place to live, explorers have discovered coal in Antarctica. This leads them to believe that Antarctica at one time was a land of swam (沼泽) and forests.

1.This text is mainly about _____.

A. the discovery of Antarctica

B. how people travel around Antarctica

C. different animals found in Antarctica

D. why it is difficult to live in Antarctica

2.We can learn from the text that _____.

A. Antarctica is a place with no animals

B. no people can survive in Antarctica

C. Antarctica is colder than any other continent on Earth

D. the temperature in Antarctica is below zero all the time

3.When is the most dangerous time to travel around Antarctica?

A. In spring. B. In summer. C. In autumn. D. In winter.

When many people are worried that there are no more heroes in the modern times, two university students who lost their lives to rescue drowning children have shown that heroes still exist.

According to the Inner Mongolia Morning Post, the tragedy (悲剧) occurred on the afternoon of December 14, 2002 when three school students skating on a frozen lake in Qingcheng Park in Hohhot fell through the ice into the freezing water.

More than 20 university students who happened to be near the place where it happened immediately went to the rescue of the children.

Two children were quickly rescued, but the third died. The child’s body was not found for three hours. Two of the rescuers, Liu Ye and Hao Longbiao, also died of cold and tiredness.

The body of Hao who took the lead in jumping into the lake was not found until the next day.

A student who was unwilling to tell his name said he and his classmates from the local college were taking photos at the lake. When they heard the children’s cries for help, they went to the ice hole hand in hand to rescue the children. But the ice kept breaking, causing most of them to fall into the icy water.

Local people held mourning ceremonies (祭奠仪式) at the lake.

Eight of the students were seriously affected by the freezing water and were being kept in hospital for further observation (观察), but their lives were no longer in danger.
