Google, the Internet search and mapping company, has developed a car that can steer without a driver.
Sometimes the reality is stranger than science fiction: Google is road-testing cars that steer, stop and start without a human driver. The goal is to “help prevent traffic accidents, free up people’s time and reduce carbon emissions.” says Sebastian Thrun, who is the project leader for the driverless car, or Carbot.
By developing the car and the software that drives it, Google wants to change how people get from place to p1ace. Eric Schmidt, one of the company’s top officials, said, “Your car should drive itself. It just makes sense.”
So far, the driverless autos have gone about 140,000 miles on California roads without people taking over the driving. Many of the roads are very busy or full of curves that challenge human drivers. The autos’ software makes it possible to know speed limits, traffic patterns and road maps. The vehicles use radar, lasers and video cameras to find other cars and avoid people crossing streets.
There has only been one accident during the testing. And in that case, the Carbot was hit from behind by a human driver when Goog1e’s car was stopped at a red light. Engineers say the driverless cars are safer than autos with people behind the wheel because the computers react much more quickly than humans.
The Carbot is still in very early testing stages. Experts agree that it will be years before you will be able to buy one. But it is likely that one day you will be sitting in the driver’s seat of a driverless car. When the auto was first invented it was called a “horseless carriage”. Now it seems that it is time for the “driverless carriage” to be part of our 1ives.

In the near future,we may be using our eyes to operate our smart-phones and tablets,even when it comes to playing popular games like Fruit Ninja.
The Gaze Group has been developing eye-controlled computer technology for nearly 20 years.But those devices have been firstly designed to help those with disabilities,and are very expensive.
“After a while,we figured out that probably the best way is to go for a mass-market way,” says Gaze’s Sune Alstrup Johansen.“where everybody would have this available."
Johansen and some of his colleagues have formed a new company,the Eye Tribe,which is hoping to develop the technology on a mass commercial level.
The technology works with the help of the computing device toward the user’s face. After making sure of the user’s eye movements,the technology is then able to easily find where a person’s eyes are moving,and then allow the eyes to control a cursor(光标).
“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at,“reads an explanation on the Eye Tribe site.
There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world.Recently Xbox released the Kinect device,which lets users control their Xbox and play certain games using only their hands,legs and voices. But still,most of these devices have been more of a gimmick than a practical way to use one’s hands to control a mobile device.Johansen said a replaceable filter(滤光器)would be a cheap,convenient way for most consumers.
And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

Can a fish hear fishermen moving along the stream? What are the facts about the ability of a fish to see? Can they tell the difference between colors?
The sharp hearing of a fish has been proved by two scientists, who trained a fish to expect its food when it heard the sound of a whistle. And a slight sound two hundred feet away could drive fishes away. That should make fishermen start thinking.
One scientist had made experiments to prove fish can recognize different colors such as red, brown, yellow and green.
Fish also have an eye for different shapes. One scientist proved this by teaching fish to connect certain patterns with food. He used a small circle and a square. If the fish swam towards the circle, they received food as a reward. If they swam towards the square, they received nothing. The fish learned in time to go to the circle but not to the square. Does this mean that in time fish might learn to leave alone all food on hooks that they have seen often before? Here is something for all fishermen to think about!
These facts help to make more believable some of the “believe it or not” stories that have been told about fish. It is clear that fish have sometimes shown their ability to gain knowledge as man does. A good example of what we might call “thinking” by a fish is given by an experience of Dr. Andrew Gage. Fishing over a bridge, he hooked a fish. It struggled and dragged the line two hundred feet away before he stopped it. Then it swam back to the bridge. The clever fish then swam round a pile and, with a sudden push, broke the line. If the story ended there, one could say that the fish had freed itself by chance. However, Gage went on fishing. Below him he could see the fish that had broken loose. After another twenty minutes the fish again seized the food on the hook. This time it did not swim out but swam round one of the piles and again broke the line.
Many stories are told of the fish that get away and the clever “old hand” ones that can’t be caught. The more often a fish is nearly caught, the more difficult it will be to interest it next time.
【小题1】The last two paragraph’s mainly discuss _________.

A.whether a fish can think as man does
B.how a fish could escape from danger
C.how to catch a fish more easily
D.whether a fish is believable
【小题2】 What’s the best title of the passage?
A.Fish can hear and see
B.How clever is a fish?
C.Fish can play tricks
D.How scientists help fishermen.
【小题3】We can infer from the last paragraph that _________.
A.it’s difficult to catch fish;
B.fish are cleverer sometimes than fishermen
C.fish seem to learn by their experience
D.fewer people will be interested in fish

Risk of death is 3.5 t0 5 times greater for obese smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 t0 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 t0 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.
Taking Charge of Your Health
Making healthy choices can be difficult when we're constantly bombarded with products that are hazardous to our health, but it's not impossible. With education and some motivation, we all have the ability to make lasting changes for the better. If you're an overweight smoker worried about gaining weight due to quitting, take heart. It's never too late to change your course and even reverse damage to some extent.

In the past, man did not have to think about protection of the environment. There were very few people on the earth, and natural resources seemed to be unlimited.
Today things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue to do this, human life on the earth will not survive.
Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on land. Yet, we continue to use more powerful machines to cut down more and more trees.
We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste is still put into rivers, but there are few laws to stop this.
We also know that if the population of the countries in the world is to rise at the present rate in a few years, there will not be enough food.
What can we do to solve these problems?
If we eat more vegetables and less meat, there will be more food available for everyone. Land that is used to grow crops can feed five times more people than land where animals are kept.
Our natural resources will last longer if we learn to recycle them.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if all of us think about the problem, we will have a better and cleaner planet in the future.
【小题1】This passage mainly tells us about ______.

A.the problems we are facing today about environment and the ways to solve them
B.the unlimited natural resources in the world
C.our rivers are being polluted by waste from factories
D.the ways early man protected the environment
【小题2】 Which of the following is NOT true?
A.If we eat more vegetables, more food can be saved.
B.In the past, there was no need for people to think about environmental protection.
C.If we keep on cutting trees, forests will disappear.
D.We shouldn’t take more and more fish out of the sea, or there will soon be no fish left.
【小题3】What is implied (暗示) in the passage?
A.Man is cleverer than any other animal.
B.Man will destroy himself if he doesn’t solve the problem.
C.Modern fishing methods are helpful in our fishing industry.
D.We should make more laws in order to survive.
【小题4】From the passage we can see that the world’s natural resources ______.
A.will never be used up B.are being polluted
C.are as plentiful as in the past D.are being used up very quickly

WASHINGTON—Two-thirds of the world’s polar bear population could be gone by 2050 if predictions of melting sea ice hold true, the US Geological Survey reported on Friday.
The fate of polar bears could be even worse than that estimate, because sea ice in the Arctic might be disappearing faster than the available computer models predict, the geological survey said in a report aimed at determining whether the big white bear should be listed as a threatened species.
“There is a definite link between changes in the sea ice and the welfare of polar bears,” said Steve Amstrup, who led the research team. He says Arctic sea ice is already at the lowest this year and is expected to retreat(退却) farther this month.
That means that polar bears—some 16,000 of them -- will disappear by 2050 from parts of the Arctic where sea ice is melting most rapidly, along the north coasts of Alaska and Russia, researchers said in a telephone briefing(简报).
Other polar bears could survive beyond that date but many of those could be gone by 2100, Amstrup said. By this century’s end, the only polar bears left might live in the Canadian Arctic islands and along the west coast of Greenland.
“It is likely to result in loss of approximately two-thirds of the world’s current polar bear population by the mid 21st century,” the report’s executive summary said.
“Because the observed trajectory(轨迹)of Arctic sea ice decline appears to be underestimated by currently available models, this assessment of future polar bear status may be conservative(保守的).”
In January, the US Fish and Wildlife Service proposed listing the polar bear as a threatened species, noting polar bears depend on sea ice as a platform to hunt seals, their main food.
Without enough sea ice, polar bears would be forced onto land, but they are poor hunters once they get out of the water and ice, the researchers said. The bears’ disappearance would probably take place as young cubs(幼兽)failed to survive to adulthood and females were unable to reproduce successfully.
【小题1】What was the US Geological Survey intended to do?

A.To determine whether the polar bear was in danger.
B.To measure how fast the sea ice melts in the Arctic.
C.To check the predictions of the computer models.
D.To find out the exact number of the polar bear.
【小题2】What causes the polar bears to disappear by 2050?
A.The pollution of the Arctic region.B.The sea ice melting at high speed
C.Fewer food sources being left.D.The temperature getting colder.
【小题3】The key to preventing polar bears dying out seems to _______________.
A.help young polar bears to survive the cold winter
B.have large number of seals living in the oceans
C.make sure there is enough sea ice in the Arctic
D.provide chances for adult polar bears to reproduce

He came into the room to shut the windows while we were still in bed and I saw he looked ill. He was shivering, his face was white, and he walked slowly as though it ached to move.
"What's the matter, Schatz?"
"I've got a headache."
"You better go back to bed."
"No. I'm all right."
"You go to bed. I'll see you when I'm dressed."
But when I came downstairs he was dressed, sitting by the fire, looking a very sick and miserable boy of nine years. When I put my hand on his forehead I knew he had a fever.
"You go up to bed," I said, "You're sick."
"I'm all right," he said.
When the doctor came he took the boy's temperature.
"What's is it?" I asked him.
"One hundred and two."
Downstairs, the doctor left three different medicines in different colored capsules(胶囊) with instructions for giving them. One was to bring down the fever, another a purgative(泻药), the third to overcome an acid condition. The germs of influenza(流感)can only exist in an acid condition, he explained. He seemed to know all about influenza and said there was nothing to worry about if the fever did not go above one hundred and four degrees. This was a light epidemic(传染病;传染性的) of flu and there was no danger if you avoided pneumonia(肺炎).
Back in the room I wrote the boy's temperature down and made a note of the time to give the various capsules.
"Do you want me to read to you?"
"All right. If you want to, " said the boy. His face was very white and there were dark areas under his eyes. He lay still in the bed and seemed very detached(超然的;冷漠的)from what was going on.
I read aloud from Howard Pyle's Book of Pirates(海盗);but I could see he was not following what I was reading.
"How do you feel, Schatz?" I asked him.
"Just the same, so far," he said.
I sat at the foot of the bed and read to myself while I waited for it to be time to give another capsule. It would have been natural for him to go to sleep, but when I looked up he was looking at the foot of the bed, looking very strangely.
"Why don't you try to sleep? I'll wake you up for the medicine."
"I'd rather stay awake."
After a while he said to me, "You don't have to stay in here with me, Papa, if it bothers you."
"It doesn't bother me."
"No, I mean you don't have to stay if it's going to bother you."
I thought perhaps he was a little lightheaded and after giving him the prescribed capsules at eleven o'clock I went out with my gun and the young hunting dog….I killed two quail(鹌鹑), and missed five, and started back pleased to have found a covey of quail close to the house and happy there were so many left to find on another day.
At the house they said the boy had refused to let anyone come into the room.
"You can't come in," he said. "You mustn't get what I have."
I went up to him and found him in exactly the position I had left him, white-faced, but with the tops of his cheeks flushed(发红)by the fever, staring still, as he had stared, at the foot of the bed.
I took his temperature.
"What is it?"
"Something like a hundred," I said. It was one hundred and two and four tenths.
"It was a hundred and two," he said.
"Who said so?"
"The doctor."
"Your temperature is all right," I said. "It's nothing to worry about."
"I don't worry," he said, "but I can't keep from thinking."
"Don't think," I said. "Just take it easy."
"I'm taking it easy," he said and looked straight ahead, He was evidently holding tight onto himself about something.
"Take this with water."
"Do you think it will do any good?"
"Of course it will."
I sat down and opened the Pirate book and began to read, but I could see he was not following, so I stopped.
"About what time do you think I'm going to die?" he asked.
"What?"
"About how long will it be before I die?"
"You aren't going to die. What's the matter with you? "
"Oh, yes, I am, I heard him say a hundred and two."
"People don't die with a fever of one hundred and two. That's a silly way to talk."
"I know they do. At school in France the boys told me you can't live with forty-four degrees. I've got a hundred and two."
He had been waiting to die all day, ever since nine o'clock in the morning.
"You poor Schatz," I said. "Poor old Schatz. It's like miles and kilometers. You aren't going to die. That's different thermometer(温度计). On that thermometer thirty-seven is normal. On this kind it's ninety-eight."
"Are you sure?"
"Absolutely," I said, "It's like miles and kilometers. You know, like how many kilometers we make when we do seventy miles in the car?"
"Oh," he said.
But his gaze at the foot of the bed relaxed slowly. The hold over himself relaxed too, finally, and the next day it was very slack(松驰的) and he cried very easily at little things that were of no importance.

Most people think the first pies were made by early Romans. They may have learned about pie making from the Greeks. These pies were sometimes made in"reeds (芦苇叶)", which were used for the purpose of holding the filling (馅 ), and were not eaten.
The Romans spread the word about pies around Europe and the word"pie"became a popular word in the 14th century. The first pie recipe (食谱) was also published by the Romans.
Pies first appeared in England as early as the twelfth century. The early pies were mostly meat pies. There was actually more crust(皮)than filling. Often these pies were made from fowl ( 家禽) and the fowl's legs were left to hang over the side of the dish and used as handles. Fruit pies were probably first made in the 1500s. It is said that Queen Elizabeth I made the first cherry pie.
Pie came to America with the first English settlers. The early settlers cooked their pies in long narrow pans. As in the Roman times, the early American pie crusts were often not eaten, but simply used to hold the filling during baking(高@考资&源*网烘焙).
Over the years, pie has become what it is today --- "the most traditional American dessert". Pie has become so much a part of American culture that we now often use the phrase "as American as apple pie".
【小题1】Which people might probably first grasp the skill to make pies?

A.The Romans.B.The Greeks.
C.The Englishmen.D.The Americans.
【小题2】Which of the following is NOT true about pies?
A.English settlers brought pies to America.
B.Early Romans ate not only pies but also the crusts.
C.The Romans first published pie recipe.
D.The word “pie ” became popular because of the Romans` efforts.
【小题3】What can best show pies have become part of American culture?
A.Americans use long narrow pans to cook pies.
B.People use "as American as apple pie" to show something about American characteristics.
C.Americans don't eat crusts but use them to hold the filling during baking.
D.Pies are the most traditional American dessert.

In the US, people prefer waiting for a table to sitting with people they don’t know. This means a hostess may not seat a small group until a small table is available, even if a large one is. If you are sitting at a table with people you don’t know, it is impolite to light up a cigarette without first asking if it will disturb them.
At American restaurants and coffee shops you are usually served tap (水龙头)water before you order. You may find the bread and butter is free, and if you order coffee, you may get a free refill(重续).
Most cities and towns have no rules about opening and closing time for stores or restaurants, though they usually do make rules for bars. Especially in large cities, stores may be open 24 hours a day.
Serving in restaurants is often large; too large for many people. If you can’t finish your meal but would like to enjoy the food later, ask your waitress or waiter for a “doggie bag”. It may have a picture of a dog on it, but everybody knows you’re taking the food for yourself.
Tips are not usually added to the check. They are not included in the price of the meal, either. A tip of about 15% is expected and you should leave it on the table when you leave. In some restaurants, a check is brought on a plate and you put your money there. Then the waiter or waitress brings you your change.
【小题1】Which statement is TRUE?

A.American people like sitting with people they don’t know.
B.Hostess always seats a small group at a large table.
C.American people never sit with people they don’t know.
D.American people would not light a cigarette if the people who sit at the same table mind their smoking.
【小题2】What is served before you order?
A.Cold water. B.Butter. C.Coffee. D. Bread.
【小题3】What do American people always do when servings are too large for them?
A.They take the food home with a doggie bag for their dogs.
B.They leave the food on the table and go away.
C.They take the food home with a doggie bag and enjoy the food later.
D.They ask the waitress or waiter to keep the food for them.
