Hare, a professor of zoology at the University of Maniloha in Winnipeg, and his team managed to record squirrels" alarm calls.The researchers studied the sounds and then played them back to 60 wild squirrels, which the scientists approached individually with a video recorder to capture(抓拍)their reponses.Some squirrels lifted their heads up and became.Alert(警惕的).Creatures that were more frightened simply ran for their lives and dived into caves.
"In effect then, whistles that mix with chucks say "there"s an enemy of average threat that"s here", and whistles without chucks say "there"s an enemy of seemingly average threat around here somewhere", while pure chirps say, "I"m hiding here because there"s an immediate danger." " Hare told.Discovery News.
Hare and some other researchers believe such sounds arc part of an advanced language that develops just as all other communication systems.
Although squirrels risk their lives when they call out to warn others of threats, other squirrels might admire this behaviour, thus increasingly the caller’s social status, like humans who look up to heroes. Hare added that other animals, such as birds, probably understand at least some squirrel language, since they also may benefit from the alarm calls.
In fact, another Canadian study found that deep-voiced, black-capped chickadees have their own language too.According to certain research, there are a lot of tidings in chickadees" calls, such as directing fellows" activities, keeping in contact between mates, and raising alarms.
While chickadees and other birds are often welcomed into gardens by homeowners, squirrels are frequently viewed as pests(害兽). Hare wishes a greater understanding of the complex social lives and communication systems of squirrels will provide “hope that humans will gain a greater appreciation and stop doing harm to these animals”.

举一反三
If there were a man on the moon—instead of mountains and valleys that just look like the face of a man—what would he be like?
He would not be like anyone you know. He would not be like anyone anybody knows.
If the man on the moon were bothered by too much heat or cold the way Earth people are, he could not stay on the moon.
The moon becomes very, very hot. It becomes as hot as boiling water. And the moon becomes very, very cold. It becomes colder than ice.
Whatever part of the moon the sun shines on is hot and bright. The rest of the moon is cold and dark.
If the man on the moon had to breathe to stay alive, he couldn’t live on the moon because there’s no air there. He’d have to carry an oxygen tank, as astronauts do. There’s no food on the moon, either. Nothing grows—not even weeds(grass).
If the man on the moon liked to climb mountains, he would be very happy. There are many high places there, such as the raised land around the holes, or craters(火山口), of the moon. Some of these rims are as tall as Earth’s highest mountains.
But if the man on the moon liked to swim, he would be unhappy. There is no water on the moon—just dust and rock.
When you think of what it’s like on the moon, you may wonder why it interests our scientists. One reason is that the moon is Earth’s nearest neighbor—it is the easiest place in space to get to.
Going back and forth between the moon and Earth, astronauts will get a lot of practice in space travel. Things learned on moon trips will be of great help to astronauts who later take long, long trips to some of the planets.
Scientists are also interested in the moon because it has no air. The air that surrounds Earth cuts down the view of the scientists who look at the stars through telescopes. A telescope on the moon would give them a clearer, closer view of the stars.(words: 411)
小题1:What is the reason why our scientists are interested in the moon.?
A.The moon is beautiful. |
B.The moon is different from the earth. |
C.The moon is Earth’s nearest neighbor—it is the easiest place in space to get to. |
D.The moon is the easiest place in space to get to and it has no air, unlike Earth. |
A.ball | B.hill | C.round edge | D.height |
A.We can learn much from research on the Moon. |
B.There may be human beings on the moon. |
C.If there were a man on the Moon, there would be many similarities between the man on the Moon and on the Earth. |
D.A telescope on the Moon would help scientists have a clearer, closer sight of the stars. |
40 , the person must recognize that there is a problem. For example, Sam’s bicycle is broken, and he cannot ride it to class as he usually does. Sam must 41 that there is a problem with his bicycle.
Next the person must 42 the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must 43 the parts that are wrong.
Now the person must look for 44 that will make the problem clearer and lead to 45 solutions. For example, suppose Sam 46 that his bike does not work because there is something wrong with the brakes. 47 , he can look in his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully.
After 48 the problem, the person should have several suggestions for a possible solution. Take Sam as an example 49, his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.
In the end, one 50 seems to be the solution to the problem. Sometimes the 51 idea comes quite 52 because the thinker suddenly sees something in a 53 way. Sam, for example, suddenly sees there is a piece of chewing gum stuck to a brake. He immediately hits on the solution to his problem: he must 54 the brake.
Finally the solution is 55 . Sam does it and finds his bicycle works perfectly. In short he has solved the problem.

Getting ready for work, you pause in front of the mirror, “Turn red,” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronics are rearranged in your shirt to change its color. Looking into the mirror, you find it hard to believe that you are 40. You look much younger. With amazing advances in medicine, people in your generation may live to be 150 years old. You’re not even middle-aged.
As you go into the kitchen and prepare to pour your breakfast cereal into a bowl, you hear: “To lose weight, you shouldn’t eat that,” from your shoes. They read the tiny electronic code on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?” A list of possible foods appear on the counter as kitchen checks its food supplies.
“Ready for your trip to space. You ask your son and daughter.” In 2005 only specially trained astronauts went into space — and very few of them. Today anyone can go to space for day trips or longer vacation. Your best friend even works in space. Handing your children three strawberries each, your add, “The doctor said you need these for space travel.” Thanks to medical advices, vaccination shots are a thing of the past. Ordinary foods contain specific vaccines. With the berries in their mouths, the kids head for the front door.
It’s time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office. Autopilot,” you command. Your car drives itself down the road and moves smoothly into traffic on the highway. You sit back and unroll your e-newspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video films rather than read it.

The system, called Driver Alert, aims to reduce deadly road accidents by 20% - 40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.
Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel. A sensor in the wristband detects this pressing action and measures the time between the sound the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.
小题1:According to the text, Driver Alert ______.
A.aims to reduce tiredness-related accidents |
B.has gone through testing at laboratories |
C.aims to prevent drivers from sleeping |
D.has been on sale for 12 months |
A.By sounding a warning. | B.By touching the wristband. |
C.By checking the driving time. | D.By pressing the steering wheel. |
A.about 400 milliseconds | B.below 500 milliseconds |
C.over 500 milliseconds | D.about 4 minutes |
A.moves more regularly | B.stops working properly |
C.opens the window for the driver | D.sounds more frequently and loudly |
I will admit that I have no problem coming up with rules. To me they make life easier and they leave no room for questioning. What can be more difficult, however, is giving my teens their freedom. I guess there are really two primary reasons for this. One is that I sometimes am afraid to give them freedom. The second is that I’m not always so sure what the freedom should be.
It helps that I have a husband with whom I can discuss these problems. We talk about them, give our thoughts and then we come up with an agreement. Sometimes one of us might be more unwilling but we know that there comes a time when we really do have to learn how to let go of the reins (缰绳) a bit.
If we try to make life have nothing but rules, we are more likely to see our teen’s rebelling (反抗). They need to know that while we do have certain expectations, we also trust them to begin making their own choices and decisions. How else can they do that unless they are given the space and room to do it?
It’s really all about balance and I will be the first to admit that it can be a challenge to carry out. However, it is a necessary part of growing up. Yes, teens definitely need rules but they also need freedom.
小题1:According to the text, we can infer that the writer________.
A.refuses to give her children freedom |
B.finds it difficult to make rules |
C.doesn’t have a good relationship with her children |
D.has trouble in giving freedom to her children |
A.strong-willed | B.rebellious | C.weak | D.independent |
A.Rules are difficult to make for parents. |
B.Rules and freedom are similarly important. |
C.We should give children freedom as much as possible. |
D.Rules are more important than freedom. |
A.Problems. | B.Children. | C.Rules. | D.Reasons. |
