 Global Positioning Systems（GPS） are now a part of everyday driving in many countries. These satellite-based systems provide turn-by-turn directions to help people get to where they want to go. But, they can also cause a lot of problems, send you to the wrong place or leave you completely lost. Many times, the driver is to blame. Sometimes a GPS error is responsible. Most often, says Barry Brown, it is a combination of the two.
We spoke to Mr. Brown by Skype （網絡電話軟件）. He told us about an incident involving a friend who had flown to an airport in the eastern United States. There he borrowed a GPS-equipped car to use during his stay. BARRY BROWN: “And they just plugged in an address and then set off to their destination. And, then it wasn’t until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived. They actually put their home address in. So again, the GPS is kind of 'garbage in garbage out'.”
Mr Brown says this is a common human error. But, he says, what makes the problem worse has to do with some of the shortcomings, or failures, of GPS equipment. BARRY BROWN: “One problem with a lot of the GPS units is that they have a very small screen and they just tell you the next turn. Because they just give you the next turn, sometimes that means that it is not really giving you the overview that you would need to know that it’s going to the wrong place.”
Barry Brown formerly served as a professor with the University of California, San Diego. While there, he worked on a project with Eric Laurier from the University of Edinburgh. The two men studied the effects of GPS devices on driving by placing cameras in people’s cars. They wrote a paper based on their research. It is called “The Normal, Natural Troubles of Driving with GPS.”
It lists several areas where GPS systems can cause confusion for drivers. These include maps that are outdated, incorrect or difficult to understand. They also include timing issues(時機問題) related to when GPS commands are given.
Barry Brown says, “ To make GPS systems better we need a better understanding of how drivers, passengers and GPS systems work together.”
小題1:In paragraph 2, Mr. Brown mentioned his friend in the conversation to _______.
A．build up his own reputation
B．laugh at his stupid friend
C．prove the GPS system is only garbage
D．describe an example of human error
小題2:What is the disadvantage of small screens in GPS equipment according to the text?
A．They just provide the next turn.B．They are harmful to eyes.
C．They make drivers tired easily.D．They often break down suddenly.
小題3: Which of the following statements would Barry Brown most likely agree with?
A．GPS units are to blame for most GPS service failures.
B．We should introduce higher standards for the driving license.
C．Cameras are urgently needed to help improve GPS systems.
D．Drivers, GPS systems and passengers should unite to improve GPS systems.
小題4:What is Mr. Brown’s attitude towards GPS?
A．Unconcerned.B．Prejudiced.
C．Objective.D．Critical.
小題5:Which of the following statements can best describe the main idea of the pasage?
A．Driving with GPS can be difficult.
B．Driving confusions can be caused by small screens.
C．Driving without GPS should be much more convenient.
D．GPS equipment in driving to be deserted or improved

小題1:D

     Say you're in the wine store and you want to buy something new. You have nothing to go by outside of the label. Will the label tell you anything you should know? Here's some general advice:
Vintage. This is the first thing we look for ourselves. You don't need to care whether 2001 or 2002 was a better year in the Sierra Foothills. The vast majority of wines at the store are meant to be drunk right away, so you make sure the wine isn't too old, particularly if you're buying it expecting lively, fresh fruitiness. We often see five-year-old Pinot Grigio and two-year-old Beaujolais Nouveau at stores, for example, so as soon as we see that kind of age on wines like those, we know we can skip them and move on(and possibly not shop there again).
Alcohol content. Too many wines have too much alcohol, which leaves them unbalanced. Sure, there are some classic wines with high alcohol levels, but many of today's regular table wines--Merlot, Chardonnay--have levels at 15% or above. Some of those might be terrific, but if we had nothing else to go on, we'd look for alcohol content at about 14% and below.
The more specific the better. A wine that says it's from Napa is probably a better bet than a wine that simply says it's from California. Unfortunately, this will also probably be reflected in the price, so this might not tell you much about value, If you care enough to know a few of famous vineyards for producing high-quality grapes, they might help you make an educated guess about quality.
Old vines. Theoretically, older vines produce fewer, but more flavorful grapes, but the problem is that no one has defined what an "old vine" is, so anyone can put this on the label. Just ignore it.
A phone number. You'd be surprised many small-production wines these days include a phone number on the back and an invitation to call the winerY, which is a sign of a highly personal winerY. We have called those numbers many times over the years and it's amazing how often the winemaker or winerY owner answers the phone.
小題1: The underlined word "Vintage" in the second paragraph probably means "________ " .
A．the place where the wine was madeB．the year when the wine was made
C．the freshness of the wineD．the label of the wine
小題2:It's better to buy
A．five-year-old Pinot GrigioB．the wine labeled from older vines
C．the wine from famous vineyardsD．two-year-old Beaujolais Nouveau
小題3: From the passage we Can infer that
A．the wine with high alcohol levels is definitely terrific
B．most wines at the store are intended to be drunk right away
C．older vines have lower production
D．some winemakers keep the promise all the time
小題4: What is paragraph 4 mainly about?
A．Geography.B．PriceC．Quality.D．Grapes.

When newspapers and radio describe the damage caused by a hurricane named Hazel,girls named Hazel are probably teased by their friends.To keep out of trouble,the Weather Bureau says,“Any resemblance between hurricane names and the names of particular girls is purely accidental.”
Some women became angry because hurricanes are given their names,but many other women are proud to see their names make headlines.They don’t even care that they are the names of destructive storms.Because more women seem to like it than dislike it,the Weather Bureau has decided to continue using girl’s names for hurricanes.
In some ways a hurricane is like a person.After it is born,it grows and develops,then becomes old and dies.Each hurricane has a character of its own.Each follows its own path through the world,and people remember it long after it gone.So it is natural to give hurricanes’ names,and to talk about them almost if they were alive.

Below is a selection from a popular science book.
If blood is red, why are veins（靜脈）blue?
Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple colour. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don’t they grow back in grown-up?
Baby (or “milk”) teeth do not last long; they fall out to make room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they’re gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine(脊柱)becomes shorter and more curved due to disuse and the effects of gravity（重力）. Many (but not all) men and women do lose height as they get older. Men lose an average of 3—4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.
Why does spinning make you dizzy(眩暈的)?
Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But, when you suddenly stop spinning the system goes out control, and your brain thinks you’re moving while you’re not!
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area—from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animals on the planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy; it’s more that a lack of exercise leaves your body weak and easily affected by disease.
小題1:What is the colour of blood in a vein near the surface of the skin?
A．BlueB．Dark reddish purple
C．RedD．Light yellow
小題2:Why do some old people look a little shrunken as they age?
A．Because their spine become more bent.
B．Because they are more easily affected by gravity.
C．Because they keep growing backwards.
D．Because their spine is in active use.
小題3:Which of the following statements about our brain is true?
A．The brains of the other mammals are as complex as those of humans.
B．When our brain senses the spinning, we will feel dizzy.
C．In the long run, our brain probably works harder than our heart.
D．Our feelings and emotions come from the most developed area in our brain.
小題4:. In this article, we can know except _____.
A．it takes four to five times as much blood to feed our brain as to feed our heart.
B．when adult teeth are gone, they cannot grow back.
C．the reason why spinning make us dizzy.
D．how we can grow taller.
小題5: What is the main purpose of the selection?
A．To give advice on how to stay healthy.
B．To report the latest discoveries in medical science.

As researchers learn more about how children's intelligence develops, they are increasingly surprised by the power of parents.The power of the school has been replaced by the home.To begin with, all the factors which are part of intelligence—the child's understanding of language，learning patterns, curiosity—are established well before the child enters school at the age of six.Study after study has shown that even after school begins, children's achievements have been far more influenced by parents than by teachers.This is particularly true about learning that is language?related.The school rather than the home is given credit for variations in achievement in subjects such as science.
In view of their power, it's sad to see so many parents not making the most of their child's intelligence.Until recently parents had been warned by educators who asked them not to educate their children.Many teachers now realize that children cannot be educated only at school and parents are being asked to contribute both before and after the child enters school.
Parents have been particularly afraid to teach reading at home.Of course，children shouldn't be pushed to read by their parents, but educators have discovered that reading is best taught individually—and the easiest place to do this is at home.Many four?and five?year?olds who have been shown a few letters and taught their sounds will compose single words of their own with them even before they have been taught to read.
小題1:What have researchers found out about the influence of parents and the school on children's intelligence?
A．Parents have greater influence than the school.
B．The school plays a greater role than parents.
C．Parents and the school have the equal power.
D．Neither parents nor the school has any influence.
小題2:Researchers conclude that________.
A．it is with the help of the teachers that children have an understanding of
language
B．curiosity is formed after the children enter school
C．children's learning patterns are developed at the early age
D．only the school can give children the opportunity to make achievements
小題3:According to the text, in which area may school play a more important role?
A．Moral education.B．Language education.
C．Physical education.D．Science education.
小題4:Many parents fail to make the most of their children's intelligence because
________.
A．they usually push the children to read at home
B．they only teach them after they enter school
C．they teach them in a wrong way at home
D．they were told by educators not to teach their children

Astronomy is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about the heavens. But man was limited by what he could see with his eyes alone.
The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens.
Each new tool added to the field of astronomy helped man reach out into space. They did not know that the planet called Saturn(土星) had rings around it. Their sight was so limited that they could not see all the planets. In the early 1700s, people thought there were only six planets. Nepture(海王星), the last of eight planets to be discovered, was not seen until 1846.
Before the spectroscope(分光鏡), man did not know what kind of gases was in the sun or other stars. Without the radio telescope, we didn’t know that radio noises came from far out in space.
Today, astronomy is a growing science. We had learned more in the last fifty years than in the whole history of astronomy.
小題1:. Thousands of years ago, people observed the stars with the limitation of their _____.
A．eyesightB．land

A world-famous Canadian author, Margaret Atwood, has created the world’s first long-distance signing device(裝置), the LongPen.
After many tiring……from city to city, Atwood thought there must be a better way to do them . She hired some technical experts and started her own company in 2004. Together they designed the LongPen. Here’s how it works: The author writes a personal message and signature on a computer tablet(手寫板) using a special pen. On the receiving end, in another city, a robotic arm fitted with a regular pen signs the book. The author and fan can talk with each other via webcams(網絡攝像機) and computer screens。
Work on the LongPen began in Atwood’s basement(地下室). At first, they had no idea it would be as hard as it turned out to be. The device went through several versions, including one that actually had smoke coming out of it. The investing finally completed, teat runs w ere made in Ottawa, and the LongPen was officially launched at the 2006 London Book Fair. From here , Atwood conducted two transatlantic book signings of her latest book for fans in Toronto and New York City.
The LongPen produces a unique signature each time because it copies the movement of the author in real time. It has several other potential applications. It could increase credit card security and allow people to sign contracts from another province. The video exchange between signer and receiver can be recorded on DVD for proof when legal documents are used.
“It’s really fun”, said the owner of a bookstore, who was present for one of the test runs. “Obviously you can’t shake hands with the author but there are chances for a connection that you don’t get from a regular book signing..
The response to the invention has not been all favorable. Atwood has received criticism from authors who think she is trying to end book tours. But she said, “It will be possible to go to places that you never got sent to before because the publishers couldn’t  afford it.”
小題1:Why did Atwood decide to invent the LongPen?
A. To set up her own company
B. To win herself greater popularity
C. To write her books in a new way
C. To make book signings less tiring
小題2:How does the LongPen work?
A．I copies the author’s signature and prints it on a book.
B．It signs a book while receiving the author’s signature.
C．The webcam sends the author’s signature to another city.
D．The fan uses it to copy the author’s signature himself.
小題3:What do we know about the invention of the LongPen?
A．It has been completed but not put into use.
B．The basement caught fire by accident.
C．Some versions failed before its test run.
D．The designers were well-prepared for the difficulty.
小題4:How could the LongPen be used in the future?
A．To draft legal documents.
B．To improve credit card security
C．To keep a record of the author’s ideas.
D．To allow author and fan to exchange videos
小題5:What could be inferred from Paragraphs 5 and 6?
A．Atwood doesn’t mean to end book tours.
B．Critics think the LongPen is of little use
C．Bookstore owners do not support the LongPen
D．Publishers dislike the LongPen for its high cost

We sometimes think global warming or climate change is a problem very far away from our lives, and that only the government needs to worry about it. But it's hardly possible to completely stay out of it ­ scientists are now 95 percent sure that humans have been the “dominant cause” of global warming trends since the 1950s.
One of the conclusions of a report released on Sept 27 by the United Nations says that human activities have caused global temperatures to rise by 0.89 0C between 1901 and 2012. That might not seem like a lot, but the truth is that a major part of that heat has been absorbed into the oceans, which is not surprising given that they cover two thirds of Earth's surface. Also, water has a much greater capacity (容量) to absorb heat than the air does, according to The Economist.　
While many greenhouse gases occur naturally and are needed to keep the Earth warm enough to support life, humans' use of fossil fuels is the main source of excess (多余的) greenhouse gases. According to CNN, by driving cars, using electricity produced by burning coal and oil or heating our homes with coal or natural gas, we release a large amount of greenhouse gases into the atmosphere.
Your body can barely feel a difference of 0.89 0C, but the Earth's ecosystems are so sensitive that even small changes can disturb them. It often starts with the smallest creatures at the bottom of the food chain, eventually affecting bigger animals, many of which could end up becoming extinct.
Global warming is also linked to an increase in extreme weather. A larger amount of carbon dioxide traps more energy inside the atmosphere. This changes the patterns of storms and rainfall in many regions and can lead to droughts and floods. Worse still, melting sea ice in warmer oceans is causing sea levels to rise at a speed of more than three millimeters per year, according to The Guardian, which also increases the risk of flooding.
“The report should serve as another wake­up call that our activities today have a profound impact on society, not only for us, but for many generations to come，” French Michel Jarraud, secretary­general of the World Meteorological Organization, said at a news conference.
小題1:The underlined word “dominant” in the first paragraph means “ ________”．
A．common　　　　 　　　B．indirect
C．secondaryD．leading
小題2:Which of the following statements is TRUE according to the passage?
A．Greenhouse gases have been proven to harm merely the Earth .
B．There is little we can do to prevent global warming.
C．Global warming can increase the chances of droughts and floods.
D．The hugeness of oceans makes them better absorbers of heat than the air.
小題3:The rise in global temperatures between 1901 and 2012 ________.
A．is more harmful to smaller creatures than bigger ones
B．is not serious because most of the extra heat has been absorbed by the oceans
C．has made the Earth's ecosystems more sensitive to changes
D．is likely to cause many species to become extinct
小題4:What is Michel Jarraud's attitude toward the report released by the UN?
A．Negative.B．Supportive.
C．Doubtful.D．Uninterested.
