In the computer age, most of us take a broadband（宽带）Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files（档案文件）download much faster than ten years ago. And the files are much bigger too.
There’s a catch, of course: You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “last mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs（郊区）, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely (稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere.
Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables (光纤电缆) promise to bring extremely fast Internet connections to more users.
Still, the “last mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication (迹象), it may not be too long before an Internet connection simply follows you wherever you go.
The underlined part “a catch” (in Paragraph 2) probably means “_____”.

A．a rare challenge	B．a desirable plan
C．an efficient device	D．a hidden problem

What can we know from the third paragraph?

A．Internet connection has not been popular in most cities.

B．Internet service providers care about rural（农村的）customers.

C．Computer is popular in developing countries.

D．It is hard to bring Internet access to users in remote areas.

Paragraph 4 mainly tells us that technological advancements _____.

A．make TV and telephone available everywhere

B．bring great change to people’s everyday life

C．make it possible for more people to use the Internet

D．bring faster Internet connections to users

What may eventually settle the “last mile” problem?

A．The broadband connection’s getting faster.

B．More and more Internet users.

C．more and more Internet connections.

D．The rapid progress in cell phone technology.

The Peales were a famous family of American artists. Charles Willson Peale is best remembered for his portraits of leading figures of the American Revolution. He painted portraits of Franklin and Jefferson and over a dozen of George Washington. His life-size portrait of his sons Raphaelle and Titian was so realistic that George Washington reportedly once tipped his hat to the figures in the picture.
Charles Willson Peale gave up painting in his middle age and devoted his life to the Peale museum, which he founded in Philadelphia. The world’s first popular museum of art and natural science mainly covered paintings by Peale and his family as well as displays of animals in their natural settings. Peale found the animals himself and found a method to make the exhibits more lifelike. The museum’s most popular display was the skeleton (骷髅) of a huge, extinct（灭绝的）elephant, which Peale unearthed on a New York farm in 1801.
Three of Peale’s seventeen children were also famous artists. Paphaelle Peale often painted still lives of flowers, fruit, and cheese. His brother Rembrandt studied under his father and painted portraits of many noted people, including one of George Washington. Another brother, Rubens Peale, painted mostly landscapes and portraits.
James Peale, the brother of Charles Willson Peale, specialized in miniatures (小画像). His daughter Sarah Miriam Peale was probably the first professional female portrait painter in America.

NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.
Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce ,or possibly erase(抹去),the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased.
The research has caused a great deal of argument. Some think it is a bad idea, While others support it.
Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories.
"Some memories can ruin people's lives . They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering."
But those who are against the research say that changing memories is very dangerous because memories give us our identity (特质). They also help us all avoid the mistakes of the past.
"All of us can think of bad events in our lives that were horrible at the time but make us who we are. I'm not sure we want to wipe those memories out, "said Rebecca Dresser, a medical ethicist.
1. The passage is mainly about_____________.
A. a new medical invention B. a new research on the pill
C. a way of erasing painful memories D. an argument about the research on the pill
2. The drug tested on people can_____________.
A. cause the brain to fix memories
B. stop people remembering bad experiences
C. prevent body producing certain chemicals
D. Wipe out the emotional effects of memories
3. We can infer from the passage that_____________.
A. people doubt the effects of the pills
B. the pill will stop people's bad experiences
C. taking the pill will do harm to people's health
D. the pill has probably been produced in America
4. Which of the following does Rebecca Dresser agree with?
A. Some memories can ruin people's lives.
B. People want to get rid of bad memories.
C. Experiencing bad events makes us different from others.
D. The pill will reduce people's sufferings from bad memories.

Have you ever seen people dance? Some dances are fast and others are slow. People’s feet always move when they dance. They keep on moving until the music stops.
People have enjoyed dancing for a very long time. This story is of a different kind of dance. It is a dance without people or music. Yet this dance is one of the oldest in the world. It is the dance of bees.
If you have ever watched bees, you know that they are very clever. They also work hard looking for food and bringing it back to their home.
The home of the bees is called a bee hive. Here hundreds even thousand of bees live. They work day and night building small walls. There they make their honey. This is the same honey that we eat.
Where does the honey come from? Bees live on food from flowers. Have you seen bees flying around a flower garden? When a bee rests on a flower, it tries to go to the centre of it. There it takes in as much food as its body can hold. Then it flies to take the food back to the hive.
At the hive, bees change flower food into honey. Then they fly away for more food.
How do the bees know where to find the best food in the sweetest flowers? One bee acts as a guide. When it discovers good flowers, it flies back to the hive and tells the others. It does this by dancing for them.
The bee dances on one side. This tells the other bees which way to go to find the flowers. But that is not all. The bee dances for some time. And the length of its dance tells the other bees how far they must fly to reach the flowers.
When the bees see the dance, they know where the flowers are. They fly away and return with more food for the hive.
Sometimes we hear the music of the bees as they fly around. But few people have ever seen them dance. Yet without that dance we might never have sweet honey to eat.
1. The writer believes that_________.
A. people dance better than bees
B. people learned dance from bees
C. bees dance more often than people
D. bees don’t like music
2. From this passage we know that the dance of bees means_______.

B. they want to show their beauty
C. they communicate with each other
D. they have nothing to do
3. Which of the following is true?
A. People get honey from flowers directly.
B. People draw honey from bees’ bodies.
C. People produce honey in a secret place.
D. People get honey from bees indirectly.
4. What character do bees have?

Most Americans enjoy moving from place to place. For example, they often drive their cars 120 to 160 kilometers away just to have dinner with a friend or even fly to Europe just for watching a football match. In some states only one person in five lives in a place for more than five years. One may be born in one city, and go to school in another. He may finish his middle school in two or three cities, and then attend a college far across the country. When he has entered business, he may possibly move from job to job. Moving from one job to another, which is called “job-hopping”, is a very common practice in the United States. Job-hopping is good to workers, because every change of a job gives them a chance to move up to a higher position and to get better pay. And job-hopping also gives bosses the chance to get new ideas and skills that different people bring to their companies and factories.
1. According to this passage, Americans often travel_______.
A. in order to have dinner with their friends

A. most people stay in one place
B. about 20% of the people live in one place
