As motorways become more and more blocked up with traffic, a new generation on flying cars will be needed to ferry people along skyways. That is the conclusion of engineers from the US space agency and aeronautical firms, who envision future commuters traveling by “skycar”.
These could look much like the concept skycar shown in the picture, designed by Boeing research and development. However, such vehicles could be some 25 years from appearing on the market. Efforts to build flying vehicles in the past have not been very successful. Such vehicles would not only be expensive and require the skills of a trained pilot to fly, but there are significant engineering challenges involved in developing them. “When you try to combine them you get the worst of both worlds: a very heavy, slow, expensive vehicle that’s hard to use,” said Mark Moore, head of the personal air vehicle(PAV) division of the vehicle systems program at Nasa’s Langley Research Center in Hampton, US. But Boeing is also considering how to police the airways-and prevent total pandemonium(吵雜狂亂的喧鬧)-if thousands of flying cars enter the skies.
“The neat, gee-whiz part is thinking about what the vehicle itself would look like,” said Dick Paul, a vice president with Phantom Works, Boeing’s research and development arm. “But we’re trying to think through all the consequences of what it would take to deploy(散開) a fleet of these.”
Past proposals to solve this problem have included artificial intelligence systems to prevent collisions between air traffic. Nasa is working on flying vehicles with the initial goal of transforming small plane travel. Small planes are generally costly, loud, and require months of training and lots of money to operate, making flying to work impractical for most people. But within five years, Nasa researchers hope to develop technology for a small plane that can fly out of regional airports, costs less than $100,000(£55,725), is as quiet as a motorcycle and as simple to operate as a car.
Although it would not have any road-driving capabilities, it would bring this form of travel within the grasp of a wider section of people. The new technology would automate many of the pilot’s functions. This Small Aircraft Transportation System(Sats) would divert pressure away from the “hub-and-spoke(中心輻射型)” model of air travel. Hub-and-spoke refers to the typically US model of passengers being processed through large “hub” airports and then on to secondary flights to “spoke” airports near their final destinations.

Many people who work in London prefer to live outside it, and to go in to their offices or schools every day by train, car or bus, even though this means they have to get up early in the morning and reach home late in the evening.
One advantage of living outside London is that houses are cheaper. Even a small flat in London without a garden costs quite a lot to rent. With the same money, one can get a little house in the country with a garden of one’s own.
Then, in the country one can rest from the noise and hurry of the town. Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh, clean air of the country. If one likes gardens, one can spend one’s free time digging, planting, watering and doing the hundred and one other jobs which are needed in a garden. Then, when the flowers and vegetables come up, one has the reward of one who has shared the secret of Nature.
Some people, however, take no interest in country things: for them, happiness lies in the town, with its cinemas and theatres, beautiful shops and busy streets, dance-halls and restaurants. Such people would feel that their life was not worth living if they had to live it outside London. An occasional(偶爾) walk in one of the parks and a fortnight’s (two weeks) visit to the sea every summer is all the country they want: the rest they are quite prepared to leave to those who are glad to get away from London every night.
【小題1】 Which of the following statements is true?

A．People who like country things prefer to live outside the city.

B．Few people who work in London prefer to live in the country.

C．One disadvantage of living outside London is that houses are cheaper.

D．The people living outside London must like gardens.

【小題2】 One can use the same money for ________ in London to buy a little house with a garden in the country.

A．getting a small flat with a garden

B．having a small flat with a garden

C．renting a small flat without a garden

D．buying a small flat without a garden

【小題3】When the flowers and vegetables in the garden come up, those _______can share the secret of Nature.

A．who live in the country

B．who have spent time working in the garden

C．who work inside the city

D．who sometimes walk in the parks

【小題4】 People who like the city life would feel that _______ if they had to live outside London. 

A．their life was meaningless

B．their life was invaluable

C．they didn’t deserve a happy life

D．they were not worthy of their happy life

People who traveled in the past had to put up with many discomforts which we do not have nowadays, and of course they traveled far more slowly. Roads were bad indeed and you often found you could not get along at all because of the mud. In dry weather many places were thick in dust and when it was stormy, trees might fall across the road and it was nobody’s business to clear them away.
Ordinary people traveled on foot or on horseback, but everyone who could afford it kept a private coach. There were public coaches too. called “stage coaches” because long journeys took several days and were done in stages, with stops over night at inns. Some stage, coaches ran only in the summer months. Others all the year around. They were very slow and crowded and passengers often became in on the way because of the swaying (搖晃).
Break downs were frequent, since many roads were not smooth. So a coach might very easily turn right over. Early in the century coach and wagon builders were encouraged to put very wide wheels on their vehicles. So that these might level the roads a little. But many people complained of this since it slowed travel down a good deal.
Most travelers during the 18th century wrote bitterly about the state of the roads. One visitor to Sussex took six hours to travel nine miles in his coach; another wrote to a friend that on time of his journeys “almost every mile was marked by the overturn of a carriage”.
【小題1】Which of the following mainly prevented people from travelling fast in the past?

A．Falling trees	B．Thick dust

【小題3】 Public coaches were called “stage-coaches” because ______. 

A．the long journey was broken into several parts

B．they were slow and crowded

C．they stopped for meals at inns

D．they served public people only

This year some twenty-three hundred teenagers(young people aged from13~19)from all over the world will spend about ten months in U.S. homes. They will attend U.S. schools, meet U.S. teenagers, and form impressions of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new languages and gain a new understanding of the rest of the world.
Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George’s family. In turn, George’s son Mike spent a year in Fred’s home in America.
Fred, a lively young man, knew little German when he arrived, but after two months’ study the language began to come to him. School was completely different from what he had expected—much harder. Students rose respectfully when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.
Family life, too, was different. The father’s word was law, and all activities were around the family rather than the individual(個人). Fred found the food too simple at first. Also, he missed having a car.
“Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it.”
At the same time, in America, Mike, a friendly German boy, was also forming his idea. “I suppose I should criticize(批評)American schools,” he said. “It is far too easy by our level. But I have to say that I like it very much. In    Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens. There ought to be some middle ground between the two.”
【小題1】This year ________teenagers will take part in the exchange programme between America and other countries.

A．twenty-three hundred

【小題4】What is particular in American schools is that________.

A．there is some middle ground between the two teaching buildings

B．there are a lot of after-school activities

C．students usually take fourteen subjects in all

D．students go out side to enjoy themselves in a car

【小題5】Which of the following is not true according to this passage?

B. Fred had his own car when he was in America.
C. Subjects seemed easy for Mike in the USA.
D. All family activities were around the individual in Germany.

A “blogger” is a person who writes on an Internet computer Web site called a “blog”. The word “blog” is a short way of saying web log, or personal Web site. Anyone can start a blog, and they can write about anything they like.
There are millions of blogs on the Internet today. They provide news, information and ideas to many people who read them. They contain links to other Web sites. And they provide a place for people to write their ideas and react to the ideas of others.
A research company called Peruse has studied more than 3,000 Web logs. It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year.
However, some people develop serious blogs to present political and other ideas. For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And American companies are beginning to use blogs to advertise their products.
At the same time, some long-standing blogs have ended. Last week, blogging leader Dave Winner closed his free blog service, weblogs.com. He says the site became too costly to continue. He started the blog four years ago, and thousands of people had written on it.
One blog that is still going strong is called Rebecca’s Pocket. It involves much useful information for readers. Rebecca Blood created the Web site in 1999. She wrote about the history of blogs on the site. That article led to a book called “The Weblog Handbook”. It has been translated into four languages so far.
Ms Blood says Rebecca’s Pocket gets about 30,000 visitors a month. She writes about anything and everything----politics, culture and movies. She recently provided medical advice. And she wrote about how to prevent people from stealing money from online bank accounts.
【小題1】The text is written mainly to ____

A．introduce an Internet computer Web site called “blog”

B．introduce a way of reading on blogs

C．tell readers about blogs

D．tell readers how to write blogs

【小題2】From the text we can learn that blogs cover almost everything except __ _.

A．different ideas

B．medical advice

C．a(chǎn)dvertisements

D．a(chǎn)ccount codes

【小題3】According to this passage , which of the following is NOT true?

A．Politicians don’t use blogs at all

B．A lot of bloggers no longer write or read blogs

C．Those who like to use blogs are mostly teenage girls

People are talking about the “new economy.” It’s very different from the “old economy”.
In the old economy, people travel to walk. They buy things in stores. They use the post office, the fax and the telephone to send information. They see people face-to-face at their jobs or in stores. People get information from newspapers, radio, television, books and libraries.
In the new economy, people do business through the “net,” which is a connection of millions of computers everywhere in the world. In the new economy, workers often work at home. They can get information online. They can communicate with employers and co-workers by e-mail. Businesses have “virtual stores”. They are websites on which customers can see the products. Businesses can sell to customers anywhere in the world.
In the new economy, people live a fast paced, convenient and colorful life. The whole world develops more quickly than before. But the new economy is a double-edge sword. Its disadvantage is also obvious. For example, the Internet has led to a huge increase in credit card cheating. Some illegal websites offer some cheap or banned goods or services. Online shoppers who enter their credit card information may never receive the goods they want to buy and their card information could even be for sale in an illegal website. So people in the new economy should be smarter and knowledgeable.
【小題1】The cause of the differences between the new economy and the old economy is ____.

A．the change of people’s idea	B．the business people do
C．the use of the Internet	D．the change of people’s life

【小題2】In the old economy, people can do the following things EXCEPT____.

A．getting information from books

B．communicating with friends by telephone

C．meeting people face to face

D．shopping online

【小題3】“But the new economy is a double-edge sword ” in the last passage means_____.

A．The new economy is as sharp as a sword

B．The new economy has advantages and disadvantages

C．The new economy is better than the old economy

D．Both the new economy and the old economy have disadvantages

【小題4】Which of the following is NOT true?

A．People can get all kinds of information on the Internet.

B．Telephone, radio, television, newspapers and so on will disappear in the new economy.

C．People in the new economy should have high quality.

D．Life in the new economy is more comfortable than the one in the old economy.

A man living absolutely alone in a desert or forest is free from other people; but he is not absolutely free. His freedom is limited in several ways. Firstly, by the things around him, such as wild animals or cliffs too steep (陡峭的) to climb. Secondly, by his own needs: he must have sleep, water, food and shelter from extreme heat or cold. Lastly, by his own nature as a man: disease may attack him, and death will certainly come to him sooner or later.
When men live together, on the other hand, protection against wild animals is easier and they can work together to get food and build shelters; but each man has to give up some of his freedom so that he can live happily with the others.
When men become organized into very large groups, and civilization (文明) develops, it is possible to get freedom from hunger, thirst, cold, heat and many diseases, so that each person can live a happier life than he could if he were living alone; but such a society can not work successfully unless the freedom of each human being is to some extent limited so that he is kept from hurting others. I am not free to kill others, nor to steal someone else's property, nor to behave in a way that offends (觸犯) against the moral sense of the society in which I live. I have to limit my own freedom myself so that others will not limit it too much: I agree to respect the rights of others, and in return they agree to respect mine.
The advantages of such an agreement are great: one man can become a doctor, knowing that others will grow food, make clothes and build a house for him, in return for the work he does to keep them healthy. If each man had to grow his own food, make his own clothes, build his own house and learn to be his own doctor, he would find it impossible to do any one of these jobs really well. By working together, we make it possible for society to provide us all with food, clothes, shelter and medical care, while leaving each of us with as much freedom as it can.
【小題1】A man living alone in a desert or forest ______.

A．is completely free	B．feels rather lonely

【小題3】 According to the passage, to do all his own jobs one would ______.

A．enjoy a complete freedom.

B．find it a happy thing to do everything at his own will

閱讀下列短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項，并在答題卡上將該項涂黑。
B
Most parents love the Internet and want their kids to use it. But a new survey in America finds almost as many also fear the online world—especially social networking sites such as My Space—and worry their kids will get in trouble with people they meet.
“The parents see the web’s incredible potential(可能性), and they know their kids have to be there.” says James Steyer, CEO of Common Sense Media, which released results from a survey that looked into parental attitudes toward the Internet. “It is also what they are scared of most.”
The study was conducted online May 5-10 by Insight Research Group. It says 80% of parents are concerned about kids meeting bad people online. That’s because young people who largely have grown up with the Net think of it as a social outlet(出口), say the researchers. To young people, the benefits of giving out some personal information to reach out to friends outweigh the risks. And the study shows they are so comfortable with the medium that 78% have a personal website or blog.
Parents also recognize the importance of the Internet. The survey shows 91% think the Net helps their children explore their passions, and 77% think the Internet is one of the most valuable education tools teens have. But 88% think it’s important to know what their kids are doing online.
Findings suggest both parents and teens need more education about using online media, Steyer says.
Internet safety has become an increasing concern for parents in America. Organizations like the Non-profit Common Sense have been trying to reach and help parents pay attention to the problem.
【小題1】 In the second paragraph, the underlined word “It” refers to_____.

A．Common Sense Media	B．the result of the survey

【小題3】 Most parents think it is important to know_____.

A．where their children give out the information	B．what kind of websites they have
C．how often they go online	D．what their children are doing online

【小題4】From the passage we can infer that_____.

A．children are too young to know how to use the Internet

B．parents must teach their children how to use the Internet

C．parents also need to learn more about using the Internet

D．the Internet is the most valuable tool for children to learn

Today, almost everyone has heard of Harry Potter. The books detailing his experiences at Hogwarts School of Witchcraft and Wizardry have aroused passion, creativity, and interest in reading throughout the world.
But have you ever considered why you are a fan of the Harry Potter series?
JK Rowling has created a list of characters and an environment for them to inhabit that appeals to both adults and children. 
The fantasy aspect of the wizarding world expands the imagination, and takes the mind to new and exciting places. Anything could happen there. Her stories contain parts of the believable and unbelievable, changing the predictability that readers commonly come across and bear in fiction. 
The main theme of the series, including good versus evil, prejudice, love, death, sacrifice, friendship and loyalty, in actuality contributes to the ever-lasting nature of the stories. At the same time, these themes remind us of classic literature, offering mature readers tales that wear like a comfortable pair of shoes, while introducing younger readers to concepts they will meet throughout their lives. 
Much of the appeal also comes from the characters. In each book, JK Rowling introduces and describes the characters in such a way that we wonder not only about their futures, but also about their pasts. Even supporting characters are suddenly more than just extras in the background. And what of Harry Potter himself? We care about Harry, because we watch him grow from an innocent boy to a powerful wizard. We see him as both Hero and Victim. He experiences endless love and extreme pain, and as readers, we experience them with him.
This perfect combination of emotion, suspense and fantasy, together with the fact that JK Rowling is a superb storyteller is the reason why we are Harry potter fans. People are fond of Harry Potter series. With books like these, it’s hard not to be.
