London, Reuters--What could annoy teenagers enough to make them stop hanging out with friends and go home？
No, it"s not a visit from their mothers, and not a threat to take away their cellphones or pocket money.
It"s high-frequency noise. The UK police recently agreed to use a device (装置) called the Sonic Teenager Deterrent. It sends out a sound that makes teenagers become so impatient and angry that they have to cover their ears tightly and walk away.
The sound is at extreme high-pitch that can be heard by those under 20. The body"s natural ability to detect some wave bands decreases almost entirely after 20, so few adults can hear the sounds. The black-box device, nicknamed the Mosquito because of its sound, can be fixed to the outside walls of shops, offices and homes. It sounds to youngsters like a crazy insect or a badly played violin. But it causes no physical damage.
A number of police forces and councils have given permission to use the system and want to install (安装) it at trouble spots.
Staffordshire Police Inspector Amanda Davies, who has given the device to shopkeepers in the Moorlands area, said," It is controlled by the shopkeepers--if they can see through their window that there is a problem, they turn the device on for a while until the group has run away."
小题1:The device can be used to _______.| A．threaten teenagers in public | | B．drive away trouble-makers under 20 | | C．help mothers control their teenage children | | D．help the police control shopkeepers |
小题2:From the passage we can know that _______.| A．young people often suffer from pains in ears | | B．shopkeepers are troubled by noisy insects | | C．high-frequency noise is beyond the listening ability of people over 20 | | D．the police invented a new device to deal with teenagers |
小题3:The purpose of the writer to write the passage is ______.| A．to advertise a new hi-tech device | | B．to tell the reader a piece of news | | C．to sell the device to shopkeepers | | D．to inform the public as the spokesman of the police |
小题4:Who will welcome the device most?| A．Shopkeepers. | B．The police. | C．Young people. | D．The producer. |

New York, the city that never sleeps, fell silent last week—schools were closed; bus and subway services were stopped; flights were canceled, and even the stock market closed for the first time since 1985. All the disorder was caused by one thing, the arrival of hurricane Sandy.
This big storm landed on Oct 29 on the US east coast and brought damaging winds, flooding, blackouts (停电) and heavy snow.
Sandy is one of the largest storms that have ever hit the US, according to the National Oceanic and Atmospheric Administration. By the afternoon of Nov1 (Beijing time), about 140 deaths were caused by the storm as it traveled across the Caribbean islands and into the US.
Unlike most hurricanes that happen during summer, Sandy was strengthened not only by warm ocean water, but also by the cold air coming from the northwest. Sandy’s power grew because of the difference in masses between the warm and wet air and cool and dry air. It became a kind of “super-storm”, the Guardian reported.
The flooding was particularly severe. Scientists said it was because Sandy’s arrival happened together with a full moon, which normally means higher-than-usual tides (潮水).
“The most worrying aspect of Sandy is the high tides,” Rhode Island Governor Lincoln Chafee told Reuters before the storm arrived. “With the full moon on Monday, with Sandy coming up the bay, we’re very concerned about flooding in our low-lying coastal areas.”
Apart from the power of Sandy itself, another reason why her arrival has caused so much damage is that its target area is crowded with big cities such as New York and Philadelphia. These urban areas are home to tens of millions of people. The flood, the snow and the blackout have brought the country’s financial and political centers to a stop.
“The size of this alone, affecting a heavily populated area, is history making.” Said Jeff Masters, a hurricane specialist.
小题1:The author mentioned the disorder in New York city at the beginning of the article to _______.| A．remind us of the problems people might face when disaster strikes | | B．introduce the disastrous influence of hurricane Sandy | | C．criticize the poor management of the city by the New York government | | D．prove New York suffered most from hurricane Sandy |
小题2:According to the text, hurricane Sandy _______.| A．only got its power from the warm ocean water | | B．grew stronger than other hurricanes because of the full moon | | C．led to flooding in many cities around the US | | D．brought with it strong winds, high tides, blackouts and heavy snowfall |
小题3:From the article, we learn that areas hurricane Sandy targeted _______.| A．were mostly high land | | B．were mostly near the sea | | C．were far away from important cities | | D．were empty as people were evacuated (疏散) |
小题4:What is the main point of the article?| A．To show how a super-storm comes into being. | | B．To explain why hurricane Sandy was so destructive. | | C．To show that big cities in the US are easily affected by huge hurricanes. | | D．To explore the best ways to avoid loss when a hurricane hits. |

For 40 years, the people of London have been happy to discover in their parks a bird that seems to have made its way from the Himalayas to the capital of England. With its shocking green body, red mouth, long tail and noisy screech(尖叫), the rose-ringed parakeet (长尾小鹦鹉) brought a vivid colour to parks in and around London.
However, the parakeets are no longer welcome. The government has suddenly woken up to the fact that there are many more parakeets in and around London making life harder for the local bird population. Government experts put the number of parakeets at around 30,000. They fear that if the number of parakeets keeps rising, these birds will push out local birds like wood-peckers, starlings and nuthatches from trees to build their own nests.
Not only that. According to an online report by The Independent, the parakeets will then also get control of most of the food available in the parks — seeds, berries, fruit and nuts. The local bird population will then have a hard time staying alive. An organization called the Royal Society for the Protection of Birds (RSPB) has asked the government to investigate (调查) what kind of a threat the parakeet brings to local birds. If the government decides that these birds are indeed a threat to local birds, steps will be taken to control the number of parakeets.
The most surprising thing about the case of the rose-ringed parakeet is that no one quite knows how the parakeets came from India and started breeding (繁殖) in areas around London.
小题1:Parakeets are no longer welcome mainly because ______.| A．the local birds are being driven out | | B．the government doesn’t like the birds | | C．they are a threat to people’s health | | D．people have a great fear of this kind of birds |
小题2:According to an online report by The Independent, ______.| A．the parakeets’ future threat is impossible | | B．the number of the parakeets is around 3,000 | | C．the parakeets should fly back to the Himalayas | | D．the local birds won’t have enough food |
小题3:People are not certain ______.| A．where the parakeets live | | B．how the parakeets breed | | C．how they flew to London | | D．when they started living in London |
小题4:The best title for this passage would be _____.| A．Help the parakeets | B．Pretty birds have trouble | | C．Birds invade London | D．Pretty birds |

TOKYO - Japan is considering plans to calm tensions（紧张）with China by acknowledging(承认) Chinese claims to the disputed islands in the East China Sea, while maintaining its own position, Kyodo News cited sources as saying on Tuesday.
The report said that the plans would allow Japan, without changing its long-held position, to compromise a little with China, which has called on Tokyo to acknowledge the existence(存在) of a dispute（冲突）over the Chinese Diaoyu Islands, referred to as Senkaku Islands in Japan.
Japan has refused to rescind its recent purchase（购买） in mid-September of three of the five Diaoyu islands from a so-called private Japanese owner, which the government says was meant to maintain（继续）the uninhabited islands in a stable manner, despite China"s strong protest.
It remains uncertain, however, whether China would be encouraged by the Japanese step to improve the tensioned ties, said Kyodo.
小题1:The passage may come from___________.| A．a magazine | B．a newspaper | C．a textbook | D．a map |
小题2:From the passage we can know________.| A．Japan will give in. | | B．China is against Japan’s purchase of Diaoyu islands. | | C．The problem between China and Japan has been settled. | | D．China is the owner of Diaoyu islands. |

Someday a stranger will read your e-mail without your permission or scan the website you’ve visited or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping calling habits
In fact, it’s likely that some of these things have already happened to you. Who would watch you without your permission? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen.
Psychologists tell us boundaries are healthy, that it’s important to reveal yourself partly to friends, family and lovers at appropriate times. But few boundaries remain. The digital bread crumbs you leave everywhere make it easy for strangers to know who you are, where you are and what you like. In some cases, a simple Google search can reveal what you think. Like it or not, increasingly we live in a world where you simply cannot keep a secret.
The key question is: Does that matter?
For many Americans, the answer apparently is “no”.
When opinion polls ask Americans about privacy, most say they are concerned about losing it. 60 percent of respondents say they feel their privacy is “slipping away, and that bothers me”.
But people say one thing and do another. Only a small number of Americans change any behavior in an effort to preserve their privacy. Few people turn down a discount at tollbooths to avoid using the EZ-Pass system that can track automobile movements. Privacy economist Acquisti has run a series of tests that reveal people will give up personal information like social security numbers just to get their hands on a 50-cents-off coupon. But privacy does matter－at least sometimes. It’s like health: when you have it, you don’t notice it. Only when it’s gone do you wish you’d done more to protect it.
小题1:What would psychologists advise on the relationships between friends?| A．Friends should open their hearts to each other. | | B．Friends should always be faithful to each other. | | C．There should be a distance even between friends. | | D．There should be fewer arguments between friends. |
小题2:Why does the author say “we live in a world where you simply cannot keep a secret”?| A．Modern society has finally developed into an open society. | | B．People leave traces around when using modern technology. | | C．There are always people who are curious about others’ affairs. | | D．Many search engines profit by revealing people’s identities. |
小题3:According to the passage, privacy is like health in that _____.| A．people will make every effort to keep it | | B．its importance is hardly understood | | C．It is something that can easily be lost | | D．people don’t value it until they lose it |
小题4:What would be the best title for the passage?| A．Value your health. | | B．Treasure your privacy. | | C．Boundaries are important between friends. | | D．The information age has its own shortcomings. |

Scientists have not come close to understanding all the different kinds of life on the planet, but US researcher Craig Venter is already working on creating the first artificial life.
Venter and his researchers made a breakthrough this August. They successfully moved the DNA of one type of bacteria(细菌) to a yeast(酵母) cell, changed it, then put it into another bacterial cell.
“Bacteria have systems that protect them from foreign DNA,” Venter explained to the BBC. In the experiment, the team managed to block this system.
The experiment was performed on a simple type of bacteria called Mycoplasma mycoides. The team took the bacteria’s genes and put them into a yeast cell.
Putting the DNA in a yeast cell allowed the team to change the genes----in this case, taking out a gene that was not necessary for the bacteria to live.
They then put the gene into a host bacteria cell. The cell went on to divide normally, producing new healthy bacteria.
In January, the team created artificial genes of a new type of bacteria. Their next goal is to put the artificial DNA into a host cell to create a new species, according to a report in Science magazine.
“If we don’t make any errors, I think it should work and we should have the first artificial species by the end of the year,” Venter said in the report.
The first artificial life from is likely to be a simple man-made bacteria, to prove that the technology can work. But that form will be followed by more complex bacteria that turn coal into cleaner natural gas, or algae that can take in carbon dioxide and change it into fuel.
Many scientists think it’s good news to have this artificial life, but others are worried that the technology to create new organisms might end up in the wrong hands, with dangerous results.
小题1:Craig Venter and his team are working to ______.| A．create a new animal | | B．clone a new species | | C．produce the first artificial bacteria | | D．develop a new system |
小题2:Which of the following is the right order of the experiment?
a. A gene was removed and put into a host bacteria cell.
b. The genes were put into a yeast cell.
c. The cell produced new healthy bacteria.
d. The genes were changed.
e. Some genes were taken out of Mycoplasma mycoides.| A．d-e-a-c-b | B．e-b-d-a-c | | C．a-d-e-c-b | D．b-e-d-c-a |
小题3:According to the passage, complex artificial bacteria, which will follow the first simple man-made bacteria, are intended to ______.| A．cure deadly diseases | | B．prepare the Earth for natural disasters | | C．prove that the technology can work | | D．improve the earth’s environment |
小题4:We can learn from the passage that ______.| A．Venter and his team are the only scientists trying to create artificial life | | B．The experiment was based on research into different kinds of life on Earth | | C．A new type of bacteria was created in January | | D．All scientists are not in favor of the research |
