A device that stops drivers form falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.
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 (方向盘). 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.
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 form sleeping
D.has been on sale for 12 months

How should a driver respond to the sounds from Driver Alert?

A.By sounding a warning. B.By touching the wristband.
C.By checking the driving time. D.By pressing the steering wheel.

We can learn form the text that the driver needs to stop for a break when his response time is ______.

A.about 400 milliseconds B.below 500 milliseconds
C.over 500 milliseconds D.about 4 minutes

     When the driver gets sleepy while driving, Driver Alert ______.

A.moves more regularly B.stops working properly
C.opens the window for the driver D.sounds more frequently and loudly

In 1883. John Roebling was inspired by an idea to build a spectacular bridge connecting New York with the Long Island. However, bridge building experts throughout the world thought this was an impossible feat and told Roebling to forget the idea, but Roebling could not ignore the vision he had in his mind of this bridge. After much discussion and persuasion he managed to convince his son Washington, an up and coming engineer, that the bridge in fact could be built.
The project started well, but when it was only a few months underway a tragic accident on the site took the life of John Roebling. Washington was injured and left with a certain amount of brain damage, which resulted in him not being able to walk or talk or even move.
"We told them so." "Crazy men and their crazy dreams.'' "It's foolish to chase wild visions." Evcryone had a negative comment to make and felt that the project should be scrapped since the Roeblings were the only ones who knew how the bridge could be built. In spite of his handicap, Washington was never discouraged.
One day he was lying on his bed in hospital, seeing the sky and the tops of the trees outside for just a moment with the sunlight streaming through the windows, and a gentle breeze bowing the flimsy white curtains apart when an idea hit him. He decided to make the best use of the only finger he could move. Thus, he slowly developed a code of communication with his wife.
He touched his wife's arm with that finger, indicating to her that he wanted her to call the engineers again. Then he used the same method of tapping her arm to tell the engineers what to do. It seemed foolish but the project was under way again.
For 13 years Washington tapped out his instructions with his finger on his wife's arm until the bridge was finally completed.
Which of the following is true of Washington and his father?

A.They are hardworking and courageous.
B.They are stubborn and bold.

In Canada and the United States, there is a new group of children called “satellite kids”, who live in one place but whose parents live in another place.
Asians are immigrating to Canada and the United States in larger numbers than ever before.Most Asians immigrate because they believe that they can give their children a better education in the West.In Asia, especially in China, Japan, and Korea, it is difficult to go to university.Students must first pass the strict national examination.However, in Canada and the United States, it is easy to go to university, and anyone who wants to go can go.As a result, Asian parents decide to leave their countries so that their children can go to university.
The problem is that when Asians arrive, they discover that finding a job and making money are more difficult in the West than in the East.Also, they find that they are very lonely, and that they miss their homes.Because of these two reasons, most Asian parents decide to go back to work while their children study in the West.Therefore, these children become “satellite kids”, and most of their parents do not know how sad it is to be a “satellite kid”.
Only until now are Canadians and Americans discovering the “satellite kid” problem.Because these children do not speak English and because their parents are not there to take care of them, they are often absent from school.To be a “satellite kid” means to grow up in a country where you know you are different and where you cannot make friends because you do not speak English well.Also, it means to grow up lonely, because your parents are elsewhere.What these “satellite kids” will probably say to their parents is that it’s better to have parents around than to have a university education.
Some Asian parents send their kids abroad because ________.

A.they hope their children may easily find a job there
B.the kids may not be accepted by universities in their own countries
C.all foreign universities are better than the ones in their own countries
D.the kids want to improve their English and make foreign friends

“Satellite kids” refer to Asian kids ________.

A.without patents
B.living abroad alone
C.with university education
D.speaking no English

Some Asian immigrant children become “satellite kids” because their parents ______.

A.want to leave their own country
B.want them to go to university
C.return to their countries to work
D.want them to be independent

What is the main idea of the passage?

A.Parents want better education for their kids.
B.Parents feel lonely and miss their families.
C.Canadians and Americans begin to notice the “satellite kids” problem.
D.Kids in foreign countries alone are badly in need of care from family.

Imagine a mass of floating waste is two times the size of the state of Texas. Texas has a land area of more than 678 000 square kilometers. So it might be difficult to imagine anything twice as big.
All together, this mass of waste flowing in the North Pacific Ocean is known as the Great Pacific Ocean Garbage Patch. It weighs about 3 500 000 tons. The waste includes bags,bottles and containers—plastic products of all kinds.
The eastern part of the Great Pacific Ocean Garbage Patch is about l 600 kilometers west of California. The western part is west of the Hawaiian Islands and east of Japan. The area has been described as a kind of oceanic desert,with light winds and slow moving water currents. The water moves so slow that garbage from all over the world collects there.
In recent years,there have been growing concerns about the floating garbage and its effect on sea creatures and human health. Scientists say thousands of animals get trapped in the floating waste,resulting in death or injury. Even more die from a lack of food or water after swallowing pieces of plastic. The trash can also make animals feel full,lessening their desire to eat or drink.
The floating garbage also can have harmful effects on people. There is an increased threat of infection of disease from polluted waste,and from eating fish that swallowed waste. Divers can also get trapped in the plastic.
Its existence first gained public attention in l997. That was when racing boat captain and oceanographer Charles Moore and his crew sailed into the garbage while returning from a racing event. Five years earlier,another oceanographer learned of the trash after a shipment of rubber duckies got lost at sea. Many of those toys are now part of the Great Pacific Ocean Garbage Patch.
In August,2009,a team from the University of California,San Diego became the latest group to travel to it. They were shocked by the amount of waste they saw. They gathered hundreds of sea creatures and water samples to measure the garbage patch’s effect on ocean environment.
How did the writer introduce the topic of the passage?

A.By giving an example.
B.By listing the facts.
C.By telling a story.
D.By giving a comparison.

What do we know about the Great Pacific Ocean Garbage Patch?

A.It is made up of various kinds of plastic products.
B.It is a solid mass of floating waste materials.
C.It lies l60 000 kilometers east of California.
D.It is described as a kind of oceanic desert.

Why do people pay attention to the Great Pacific Ocean Garbage Patch?

A.Because it may prevent the flow of ocean water.
B.Because the polluted plastic articles will move up the food chain.
C.Because it may be from an island in the pacific.
D.Because ships may be trapped in the floating waste.

The purpose of writing this passage is to____________.

A.warn people of the danger to travel in the pacific
B.analyze what caused the waste patch in the pacific
C.give advice on how to recycle waste in the ocean
D.introduce the Great Pacific Ocean Garbage Patch

John Davis doesn’t use his GPS system in his car. Instead of guiding the direction, the Delaware farmer uses it to determine where and how much fertilizer to use on the crops on his 4,000-acre family-owned farm. Technological advances like that last year helped Davis and other Ohio farmers set a record for corn product. Ohio's corn crop in 2009 totaled 546 million bushels(蒲式耳), despite a cooler and wetter than normal spring, a dry summer and a delayed, wet harvest. Davis said. “I knew it would be a good crop, but it was much better than we expected.”
A farmer can map his fields on GPS, spotting where soil turned out to be least fertile(肥沃的) and using more fertilizer the next year in those areas where corn didn’t grow as well.
Although Ohio farmers produced more corn, it was grown on less land than in the past years. Total area used for corn in Ohio was 3.35 million acres, about the same as in 2008 but down from 3.85 million acres in 2007, said Dwayne Siekman, director of the Ohio Corn Growers Association. “When you look at the total number of acres in Ohio used for corn, it’s clear that farmers are able to do more with less,” he said. “American farmers can grow five times more corn on 20 percent less land than they did in the 1930s, saying that modern farming techniques are necessary for a growing demand in the world today.” That technology includes using improved seeds that can withstand(忍受) greater temperature extremes and pests, Siekman said.
Farmers aren't the only ones who benefit. Consumers(消费者) do, too, as food costs reduce in the face of “enough supplies of corn,” said Fred Yoder, who runs a 1,500-acre corn, soybean and wheat farm in Plain City. “This is the best, highest-producing corn crop that I've raised in 30 years,” he said.
Most people usually use the GPS system for ______.

A.driving their cars
B.telling the position
C.mending the car
D.supplying the sunshine

The farmers in Ohio use GPS to ______.

A.check if the soil is fertile in some areas
B.control the rain of the place
C.water the crops if the weather is dry
D.draw the map of all the crops

Why did Ohio farmers produce more corn?

A.Because they expanded more land to grow corn
B.Because they turned to technological advances
C.Because they used more and more fertilizer.
D.Because they supplies themselves with more money.

From the passage, we can know _____.[

A.John Davis hadn’t expected a good harvest.
B.farmers grew less land than in the 1930s
C.improved seeds cost much more money
D.the output of corn in the same field is increased.

Shakespeare, more perhaps than any other writer, made full use of the greatest resources of the English Language.Most of us use about five thousand words in our normal employment of English; Shakespeare in his works used about twenty-five thousand! There is probably no better way for a foreigner to appreciate the richness and variety of the English language than by studying the various ways in which Shakespeare uses it.Such a study is well worth the effort, even though some aspects of English usage, and the meaning of many words, have changed since Shakespeare’s day.
However, it is surprising that we should know comparatively little about the life of the greatest English author.We know that Shakespeare was born in 1564 in Stratford-on-Avon, and that he died there in 1616.He almost certainly attended the Grammar School in the town, but of this we cannot be sure.We know he was married there in 1582 to Anne Hathaway and that he had three children.We know that he spent much of his life in London writing his masterpieces.But this is almost all that we do know.
However, what is important about Shakespeare’s life is not its incidental details but its products, the plays and the poems.For many years scholars have been trying to add a few facts about Shakespeare’s life to the small number we already possess and for an equally long time critics have been theorizing about the plays.Sometimes, indeed, it seems that the poetry of Shakespeare will disappear under the great mass of comment that has been written upon it.
Fortunately this is not likely to happen.Shakespeare’s people have long delighted not just the English but lovers of literature everywhere, and will continue to do so after the scholars and critics and all their works have been forgotten.
This passage is about

A.the great length of each chapter
B.the great varieties in writing styles
C.the richness of the content in Shakespeare’s works
D.the rich English language used by Shakespeare in his works

According to the writer, which of the following remains uncertain about Shakespeare?

A.His date of birth
B.His marriage
C.His life in the Grammar School
D.His date of death

It can be inferred from Para 3 that

A.not all the comments on Shakespeare’s works have produced good effects
B.scholars have successfully collected facts about Shakespeare’s life
C.critics are more interested in Shakespeare’s play than his poetry
D.the details of Shakespeare’s life are more important than his literary works

What does the last sentence in Para 3 mean ?

A.People don’t think the poetry of Shakespeare good any more.
B.People pay more attention to the comment than the poetry of Shakespeare.
C.People can’t see the poetry of Shakespeare any more.
D.The comment is printed on the poetry of Shakespeare.
