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.

Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew (肌腱). And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.
Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch (縫合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection.
Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle (腳踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical. It could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement (侵犯). Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties (版稅). In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
小題1:Barthelemy Thimonnier’s garment factory was burned down because __________.
A．people did not know how to put out the fire
B．Elias Howe thought Thimonnier had stolen his invention
C．the sewing machines couldn’t work finally
D．workers who feared the loss of their jobs to a machine set fire
小題2:Why did the court force Isaac Singer to pay Elias Howe a lifetime of royalties?
A．Because the judge was against Singer for his unfriendly attitude.
B．Because Howe had already patented the lockstitch used by Singer.
C．Because Singer had borrowed money from Howe and never repaid it.
D．Because Singer and Howe had both invented the same machine.
小題3:Which of the following would be the best title for this passage?
A．A Stitch in Time Saves Nine
B．The Case between Howe and Singer
C．Patent Laws on the Sewing Machine
D．The Early History of the Sewing Machine

Our senses aren't just delivering a strict view of what’s going on in the world; they're affected by what’s going on in our heads. A new study finds that hungry people see food-related words more clearly than people who've just eaten.
Psychologists have known for decades that what's going on inside our head affects our senses. For example, poorer children think coins are larger than they are, and hungry people think pictures of food are brighter. Rémi Radel of University of Nice Sophia-Antipolis, France, wanted to investigate how this happens.
Does it happen right away as the brain receives signals from the eyes or a little later as the brain’s high-1evel thinking processes get involved. Radel recruited 42 students with a normal body mass index. On the day of his or her test, each student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10 minutes; others were given an hour to get lunch first. So half the students were hungry when they did the experiment and the other half had just eaten.
For the experiment, the participant looked at a computer screen. One by one, 80 words flashed on the screen for about l/300th of a second each. They flashed at so small a size that the students could only consciously perceive. A quarter of the words were food-related. After each word, each person was asked how bright the word was and asked to choose which of two words they’d seen-a food-related word like cake or a neutral word like boat. Each word appeared too briefly for the participant to really read it.
Hungry people saw the food-related words as brighter and were better at identifying food- related words. Because the word appeared too quickly for them to be reliably seen, this means that the difference is in perception, not in thinking processes, Radel says. "This is something great to me. Humans can really perceive what they need or what they strive for. From the experiment, I know that our brain can really be at the disposal of our motives and needs. "Radel says.
小題1:Why was there a delay on the day of the experiment?
A．Because hungry people needed time to fill their stomach.
B．Because Radel wanted to create two groups of testers, hungry and non-hungry.
C．Because noon was not the right time for any experiment.
D．Because Radel needed time to select participants in terms of body mass index.
小題2:What does the writer want to tell us?
A．Human’s senses aren’t just delivering a strict view of what’s going on in the world.
B．What’s perceived by our senses affects our way of thinking.
C．Human brains can really be at the disposal of our motives and needs.
D．Thinking processes guarantee the normal functions of our senses.
小題3:What can we infer from the passage?
A．42 participants are too small a number for a serious investigation.
B．An experiment with hungry and non-hungry participants is not reliable.
C．Our thinking processes are independent of our senses.
D．Humans can perceive what they need without involving high-level thinking processes

Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed.
There are different kinds of pollutants, each of which comes from different sources. It is necessary to identify the source of pollution, in order to make a policy to eliminate them.
Different products, processes and activities of our industrialized world together form the major source of pollution. The forms of pollution can be mainly divided into three kinds—solid, liquid and gas.
These pollutions have greatly damaged our planet and continue to do so. In fact, pollution is threatening our existence. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even posed a great threat to man’s existence.
We must face the situation that exists and take action to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the public must receive the education about the danger of pollution and so on.
The earth is our home and we have the duty to take care of it for ourselves and our later generation. Fortunately, more and more people have realized these problems. Measures have been taken to deal with these situations by the government. Laws have been passed to stop pollution, I hope the problems will be solved in the near future and our home will become better and better.

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.
小題1:This passage mainly tells us about ______.

Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger , but we also affect our water supply in less obvious ways. You may wonder how paving(鋪砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺). Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference, too In the United States , a family of four can use 1. 5 tons of water a day! This shows how much we depend on water to live, but there’s a lot we can do to lower the number.
You can take steps to save water in your home. To start with use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗機(jī))only when it is full 。Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
小題1:Which of the following is most likely to lead to less groundwater?
A．Using river water.B．Throwing batteries away.
C．Paving parking lots.D．Throwing rubbish into lakes.
小題2:What can be inferred from the text?
A．All water shortages are due to human behavior.
B．It takes a lot of effort to meet our water needs.
C．There is much we can do to reduce family size.
D．The average family in America makes proper use of water.
小題3:The last paragraph is intended to             .
A．show us how to fix leaks at home
B．tell us how to run a dishwasher
C．prove what drinking glass is best for us
D．suggest what we do to save water at home
小題4:The text is mainly about          .
A．Why paving roads reduces our water
B．how much we depend on water to live
C．why droughts occur more in dry climates
D．how human activity affects our water supply

Family Vs Technology
Modern technology certainly changes family behavior, but does it really damage family life as many people fear? Not necessarily, says Dr. Silva, a professor in Sociology(社會學(xué)) at the Open University, she also argues it is wrong to assume technology erodes(腐蝕，侵蝕) the quality of family life.
“There is the idea that technology has an influence on the family and the family suffers. My take is quite different,” she explains. “Technological change happens because people’s lives change. And it is people’s choices of how to live that creates processes of innovation(革新) as well. The family has a role like the economy or like technology itself in changing the world. The imagination is important in driving the things technologists want to find for our daily lives. People desire to see nature as it is, so color television comes about,” she says.
In another case, the increase in working mothers helped create a market for labor-saving kitchen equipment. “The time that women have to shop every day for food is no longer available so there is a need to have a refrigerator for food storage,” says Dr. Silva. “The need to cook that food more easily and quickly, means you have developments in cooking technology like the microwave oven(微波爐). The microwave oven already existed because it was developed for the navy during World War Two but it wasn’t used in ordinary families until the early 1980s.
“Technologies for housework were as important as those for work itself,” she says, “So washing machines, refrigerators and microwave ovens are terribly important. We couldn’t imagine what life would be like if we didn’t have them.” Technological changes in the kitchen have played an important role in the changes of family behavior, creating a new social focus in the home.
“With advanced technology, you can feed the family in an easier manner. People can do housework with less difficulty. But that doesn’t mean that family practices are not important — it’s just a different way of doing things.”
小題1:What is Dr. Silva’s attitude towards the effect that technology has on family life?
A．Worried.B．Optimistic(樂觀的).
C．Puzzled.D．Uncertain.
小題2:What causes advances in technology according to Dr. Silva?
A．People’s love for nature.
B．Great changes in people’s way of life.
C．People’s desire to change the world.
D．The wonderful imagination in inventing things.
小題3:What can we learn from the passage?
A．The microwave oven was first used by working mothers.
B．People cook less because of modern kitchen equipment.
C．Technology has little effect on the changes of family behavior.
D．People need less skill to do housework due to advanced technology.
