An energy watchdog is alarmed about the threat to the environment from the increasing electricity needs of gadgets（小装置）like MP3 players, mobile phones and flat screen TVs.
In a report today, the Paris-based International Energy Agency says new electronic gadgets will be three times their energy consumption by 2030 to 1,700 terawatt hours（千瓦时）, which is equal to today's home electricity consumption of the United States and Japan combined.
The world would have to build around 200 new nuclear power plants just to power all the TVs, iPods, PCs and other home electronics expected to be plugged in by 2030,when the global electric bill to power them will rise to $200 billion a year, the agency said.
“Consumer electronics is the fastest growing area and the area with the least amount of policies in place to control energy efficiency, ” said Paul Waide, a senior policy analyst at the agency.
Electronic gadgets already account for about 15 percent of household electric consumption, a share that is rising rapidly as the number of these gadgets multiplies. Last year, the world spent $80 billion on electricity to power all these household electronics, the energy agency said.
“ Most of the increase in consumer electronics will be in developing countries, where economic growth is the fastest and ownership rates of gadgets are the lowest , ” Waide said.
“This will jeopardize efforts to increase energy security and reduce the amount of greenhouse gases blamed for global warming.” the agency said. Existing technologies’ could cut down gadgets’ energy consumption by more than 30 percent at no cost or by more than 50 percent at a small cost, the agency estimates, meaning total greenhouse gas emissions（排放） from households’ electronic gadgets could be held stable（稳定的） at around 500 million tons of CO2 per year.How many terawatt hours did the energy consumption of new electronic gadgets reach?
| A．Nearly l, 700. | B．Nearly 600. | C．About 200. | D．About 60. |
What is the condition in the area of consumer electronics?
| A．There are a lot of rules to control the market. |
| B．There are few policies to control energy efficiency. |
| C．There are few choices for the customers. |
| D．There are lots of regulations to protect consumers' rights. |
The underlined word “jeopardize” in the last paragraph probably means “ ”.
| A．harm | B．inspire | C．strengthen | D．encourage |
We can know from the last paragraph that existing technologies ___________.
| A．are able to control gadgets’ energy consumption |
| B．could do nothing about gadgets’ energy consumption |
| C．could only cut down gadgets’ energy consumption by 30 percent |
| D．cut down gadgets’ energy consumption at great cost |
Americans get some of their news and entertainment from public television and radio. These public media receive money to operate from private citizens, organizations and government. Many of their programs are educational. But most of the American media are run by businesses for profit. These privately owned media have changed greatly in recent years. Newspapers, magazines and traditional broadcast television organizations have lost some of their popularity. At the same time, online, cable and satellite media have increased in numbers and strength. So have media that serve racial groups and those communicating in foreign languages.
In general, more media than ever now provide Americans with news and entertainment. At the same time, fewer owners control them. Huge companies have many holdings(股份). In some areas, one company controls much of the media. One dramatic change in American media is the increased success of cable television. It comes into most homes over wires. It does not use the public airwaves to present programs, as broadcast television does. Like broadcast television, most cable television programs perform advertisements. This is true although people must pay to see cable television in their homes. Thirty years ago, few people had cable. Today, about sixty-eight percent of American homes have cable television. Television by satellite also is gaining popularity.
Over the years, traditional broadcast organizations have tried to appeal to as many watchers as possible. Many cable companies, however, present programs for one special group of viewers. For example, there are cable stations for people who like books, cooking, travel, golf or comedy.Which of the following is true about American public media?
| A．They depend on the government. |
| B．They are controlled by the government |
| C．They are free |
| D．They can earn money. |
Which of the following properly shows the change in these privately owned media?
| A．Newspapers are getting more popular. |
| B．Satellite media is getting more popular. |
| C．Traditional media also serve racial groups. |
| D．Some media make their programs in foreign languages |
From the second paragraph, we learn that .
| A．broadcast TV and cable TV programs include sales messages |
| B．more media are out of control |
| C．American media is dramatic |
| D．cable TV is free |
What would be the best title for the text?
| A．American news and entertainment |
| B．Public television and radio media |
| C．media in the United States |
| D．Cable programs in the United States |

If you see a group of people dancing and singing on the street or in the railway station, you don't need to feel surprised. They are a flash mob(暴民). Who are they? Are they mobs? Don't be confused by their name. Actually, a flash mob is a group of people who gather suddenly in a public place, do something unusual for a brief period of time, and then quickly disappear.
They are usually organized with the help of the Internet or other digital communications networks. The messages may be sent to friends, who send to more people. At a predetermined time, they gather and perform some activities such as exchanging books, coming together to look at the sky, waving their hands and yelling something at the top of their voice for 30 seconds. Then, they quickly disappear before the police can arrive. Using mobile phones, the flash mob can change its place if the first one has been cancelled for any reason.
Bill Wasik, senior editor of Harper's Magazine, organized the first flash mob in Manhattan in May 2003 and the first successful flash mob gathered on June 3, 2003. Wasik claimed that he created the flash mob as a social experiment designed to laugh at fashion seekers and stress the cultural atmosphere of wanting to be an insider or part of “the next big thing”.
Flash mob gatherings can sometimes shock people. Such an activity might seem amusing and magical, but it also might frighten people who are not aware of what is taking place. Undoubtedly, flash mob can serve as good political tools and have great potential, such as using flash mob to advertise a product.
The flash mob is now becoming more and more popular. People use it to do many things. For example, in 2009, Michael Jackson’s fans took part in a flash mob to remember him. Hundreds of his fans gathered singing and dancing Michael’s famous song “Beat It” together. Flash mobs give people from all walks of life an opportunity to come together to create a memory.What is NOT the feature of the flash mob?
| A．It can get together quickly. |

阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
If you have a little child, who hates sitting in a car seat, then the FreedomRide is the answer to your problem.
Would you want to be stuck in an unchangeable position every time you’re in the car? No. You wouldn’t.
When an adult sits in a car for any length of time, we stretch, we change the position, we move our legs again and again. We do this without thinking. But kids in a traditional car seat can’t do this. They are stuck in one position, and they can’t move. We move because the circulation of blood needs to be recovered in our legs as we sit in the same position for any longer.
In a traditional car seat, the child can’t move to reduce the pain, so it puts them in anger.
The FreedomRide lets them have a little freedom, and still be safe. The 5-Point Harness(背带)gives them additional safety over a traditional child car seat.
I am the Webmaster for islandbreeze.com, and when JoeySafe asked us to redo their website, I was attracted by this system. That is because I have two small children, both girls, aged 3 and 4 and we obviously use car seats. I lived in Southern California, and every couple of months, my wife, the girls and I, go to see grandma who lives in Nevada. It’s a 5-hour drive, so the FreedomRide works well. Our trips are so much better now, especially since there is more room in the car without the car seats.
The FreedomRide really did make it easier to go on trips. The only thing you need when you use the JoeySafe instead of your old child car seat is a pillow. Besides, my kids want to take a pillow anyway! As a dad, I feel safe driving with the kids in the FreedomRide. I am a very safety-oriented person.From the text we can infer the FreedomRide is a _______.
| A．car seat | B．car for children |
| C．safety belt | D．game on islandbreeze.com |
The FreedomRide is likely to be designed for________.
| A．a person hating sitting in the car for long |
| B．an adult often driving a traditional car |
| C．a child requiring some freedom in the car |
| D．a driver needing comfortable seats |
The purpose of the last two paragraphs may be to ________.
| A．support the topic of the child car safety |
| B．describe the advantage of the FreedomRide |
| C．introduce the detail of the author’s work and web. |
| D．describe what the author does with his child car seat |
The next part following the last paragraph may mention________.
| A．the way of ordering |
| B．the way of communicating |
| C．the inventor of this product |
| D．the advantage of the product |

Oliver Twist was born in a workhouse, and when he arrived in this hard world, it was very doubtful whether he would live beyond the first three minutes. He lay on a hard little bed and struggled to start breathing.
Oliver fought his first battle without much assistance from the two people present at his birth. One was an old woman, who was nearly always drunk, and the other was a busy local doctor, who was not paid enough to be very interested in Oliver’s survival. _______________
However, Oliver managed to draw his first breath, and then announced his arrival to the rest of the workhouse by crying loudly. His mother raised her pale young face from the pillow and whispered, “Let me see the child, and die.”
The doctor turned away from the fire, where he had been warming his hands. “You must not talk about dying yet,” he said to her kindly. He gave her the child to hold. Lovingly, she kissed the baby on its forehead with her cold white lips, then stared wildly around the room, fell back—and died. “Poor dear!” said the nurse, hurriedly putting a green glass bottle back in the pocket of her long skirt.
The doctor began to put on his coat. “The baby is weak and will probably have difficulties,” he said. “If so, give it a little milk to keep it quiet.” Then he looked at the dead woman. “The mother was a good-looking girl. Where did she come from?”
“She was brought here last night,” replied the old woman. “She was found lying in the street. She’d walked some distance, judging by her shoes, which were worn to pieces. Where she came from, where she was going to, or what her name was, nobody knows.”
The doctor lifted the girl’s left hand. “The old story,” he said sadly, shaking his head. “No wedding ring, I see. Ah! Good night.”
And so Oliver was left with only the drunken nurse. Without clothes, under his first blanket, he could have been the child of a king or a beggar. But when the woman dressed him later in rough cotton clothes, yellow with age, he looked exactly what he was—an orphan in a workhouse, ready for a life of misery, hunger, and neglect.
Oliver cried loudly. If he could have known that he was a workhouse orphan, perhaps he would have cried even more loudly.
There was no one to look after the baby in the workhouse, so Oliver was sent to a special “baby farm” nearby. There, he and thirty other children rolled around the floor all day, without the inconvenience of too much food or too much clothing. Mrs Mann, the old woman who “looked after” them, was very experienced. She knew what was good for children, and a full stomach was very dangerous to their health. She also knew what was good for herself, so she kept for her own use the money that she was given for the children’s food. The board responsible for the orphans sometimes checked on the health of the children, but they always sent the beadle, a kind of local policeman, to announce their visit the day before. So whenever the board arrived, of course, the children were always neat and clean.
This was the way Oliver was brought up. Consequently, at the age of nine he was a pale, thin child and short for his age. But despite frequent beatings by Mrs Mann, his spirit was strong, which was probably the reason why he managed to reach the age of nine at all.
On Oliver’s ninth birthday, Mr Bumble, the beadle, came to the house to see Mrs Mann. Through the front window Mrs Mann saw him at the gate, and turned quickly to the girl who worked with her.
“Quick! Take Oliver and those others upstairs to be washed!” she said. Then she ran out to unlock the gate which was always kept locked.According to the passage, a workhouse was where ________.

Wind turbines are efficient sources of cheap energy but also a source of concern as their huge spinning blades (叶片) frequently kill birds and bats. A new type of wind generator developed in Spain offers a creative solution to that problem.
In 2002, Spanish inventor David Yanez saw a short film about the Tacoma Narrows Bridge in the U.S., collapsing in strong wind. It was a vivid example of the powerful vibrations wind can create when it blows past a long pole, such as a car antenna or even a stick of bamboo. It gave him the idea for a new type of wind-energy generator.
“The initial philosophy or spirit was to create a generator of dreams that had all the qualities one would want: It should be as cheap as possible, need as little maintenance as possible, the setup as simple as possible,” he said.
Yanez and his friend Raoul Martin took the idea to an engineering firm, where they were told it would never work. Undiscouraged, they started experimenting on their own in a small wind tunnel they built.
Good initial results were repeated by a larger working model called Vortex (涡旋) installed in a nearby field. “What we have is a mast (桅杆), which is the top piece and acts as a blade,” Yanez said. “It’s constructed from the same material as a conventional generator, and what it does is it oscillates (振荡), transmitting the oscillation to a conventional alternator, which by its own oscillation converts the wind’s energy into electric energy.”
Yanez said the output of the 6-meter-tall generator, and even that of smaller models, was better than expected. The Vortex creates about 30 percent less energy than a comparable bladed wind turbine, but it is lighter and cheaper to build and maintain. It is made mostly of reinforced plastic and has very few moving parts. Also, it does not create noise and—even more important for many environmentalists—it does not present a threat to passing birds.
The current prototype works at wind speeds ranging from 1.5 to 7 meters per second. The inventors say the next step is building a 12.5-meter tall bladeless generator with a 4-kilowatt capacity that could power small businesses or individual homes, or provide supplemental power to a main grid. The commercial version of the Vortex Bladeless generator should be ready for the market by 2017.The author mentions a short film about the Tacoma Narrows Bridge to show ________.
| A．what the initial philosophy or spirit was |
| B．what inspired Yanez to create the generator |
| C．how the bridge was destroyed in strong wind |
| D．how wind creates powerful vibrations |
What do we know from the passage?
| A．The original idea was considered as practical in an engineering firm. |
| B．Yanez and Martin’s initial tests by themselves proved to be successful. |
| C．The material for constructing the mast is different from that of the past. |
| D．The new generator is better at creating energy than a comparable bladed one. |
What would be the best title for the passage?
| A．Bladeless wind-power generator is friendly to birds. |
| B．Wind turbines are efficient sources of cheap energy. |
| C．A new generator will come onto the market by 2017. |
| D．Yanez has made a generator for the benefit of people. |
