Statistically, air travel is by far the safest way to travel, and you can make flying even safer, just by following these simple rules. As your chances of being involved in an air accident are practically nil（不存在）, many of these tips concern what you should and shouldn"t do to make your journey safer when you are airborne（升空的）.
Fly on non-stop routes
Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures.
Choose larger aircraft
Although small aircraft have very good safety records, those with more than 30 passenger seats are designed to comply（遵守）with much stricter regulations and are tested more regularly to make sure they still comply. Also, in t he unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival.
Pay attention to the pre-flight safety briefing
The information may seem repetitious（重复的）, but it"s worth listening to the flight attendants. And even if you’ve flown before, it doesn’t mean you know everything about the aircraft you"re on, such as the location of the closest emergency exit.
Store things safely
Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence（气流）.
Keep our seat belt fastened while you are seated
Cabin crew always tell you this, but it’s important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to. The general rule of flying is this: If you are told to do something, do it first and ask questions later.
Let the flight attendant pour your hot drinks
Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them.

Facebook is now used

by 30 million people in the UK, about half the population.
Joanna Shields, vice president of Facebook Europe, made the announcement this morning at a media conference in London.
She said: "We can announce today that we have reached 30 million in the UK, which we are really excited about."
Globally, Facebook has more than 500 million registered users, a milestone it hit last summer. Last July, it also revealed that it had 26 million registered UK users. In the last eight months, it has attracted four million extra UK users, bringing the UK total to 30 million, while in January 2009, Facebook had only 150 million registered users.

Last year, Zuckerberg, Facebook"s founder, said it was "almost a guarantee" that the site would hit one billion users. He explained: "If we succeed in innovating, there is a good chance of bringing this to a billion people...it will be interesting to see how it comes true."
One third of women aged 18 to 34 check Facebook when they first wake up, before even going to the toilet, according to research. Twenty-one per cent of women aged between 18 to 34 check Facebook in the middle of the night, while 42 per cent of the same group think it is fine to post drunken photos of themselves onto the social network, a study by Oxygen Media found.
Shields was speaking this morning at the Financial Times Digital Media and Broadcasting Conference about the power Facebook"s referrals can bring to media sites, such as newspapers and TV services.
She explained that the average Facebook user has 130 friends who they share links to media sites with on a regular basis. "Media companies which take advantage of that are really seeing the benefits", Shields said.
Shields refused to say whether Facebook would develop its own mobile phone operating system and also said it was "silly" that Google had recently disabled the feature (特点) which allowed Google users to sync their contacts with Faceboo

k friends.

During the last twenty years there has been increasing concern with the quality of the environment. Along with air and water pollutions, noises pollution has been recognized as a serious pollutant. As noise levels have risen, the effects of noise have become more apparent.
Noise is defined as "unwanted sound". Causes of noise pollution include traffic, aircraft, rock bands, barking dogs, televisions, garbage trucks, and noise from neighbors, voices, alarms, and watercrafts. Studies show that over forty percent of Americans are disturbed at home or lose sleep because of noise pollution.
Noise has bad effects on people and the environment. Noise causes hearing loss, interferes (妨碍) with human activities at home and work, and is in various ways dangerous to people"s health and well being.
When we think, talk, listen to music, or sleep, we need quiet. Even low levels of noise can be

annoying or frustrating. Sudden increases in volume can make sounds annoying. The quieter the background is, the more penetrating a noise can be.
Noise can also make instructions or warning unclear, resulting in accidents. Louder noise bursts can be more disruptive (破坏性).Continued stress can lead to high blood pressure, which is the major cause of some diseases.
Long exposure to noise levels above eight-five decibels (分贝) can damage inner cells and lead to hearing loss. Noise can result in the involuntary fear response and can cause adrenaline (肾上腺素) to be pumped into the bloodstream, the heart rate to quicken, muscles to tense, breathing to increase, and the digestive system to slow down.
Local government has the responsibility to fight noise pollution. For example, it can regulate the speed of trains through their community. On the other hand, a responsible citizen will never make noise pollution wherever he is.

It happened one morning 20 years ago. A British scientist Alec Jeffrey came across DNA fingerprinting: He identified the patte

rns of genetic material that are unique to almost every individual. His discovery changed everything from the way we do criminal investigations to the way we decide family law. But the professor of genetics at the University of Leicester, UK, is still surprised, and a bit worried, by the power of the technology he released upon the world.
The patterns within DNA are unique to each individual, except identical twins, who share the same pattern. The ability to identify these patterns has been used to convict(证明…有罪) murderers and to clear people who are wrongly accused. It is also used to identify the vi

ctims of war and settle disputes over who is the father of a child.
Jeffrey said he and his colleagues made the discovery by accident while tracking genetic variations(变异). But, within six months of the

discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents’ son.·In 1986, it was used for the first time in a British

criminal case: It cleared one suspect after being accused of two murders and helped convict another man.
DNA testing is now very common. In Britain, a national criminal database established in 1995 now contains 2.5 million DNA samples. The U.S. and Canada are developing similar systems. But there are fears about the stored DNA samples and how they could be used to harm a person’s privacy. That includes a person’s medical history, racial origin or psychological profile. “There is the long-term risk that people can get into these samples and start getting additional information about a person’s paternity(父子关系) or risk of disease,” Jeffrey said.
DNA testing is not an unfailing proof of identity. Still, it is considered a reasonably reliable system for determining the things it is used for. Jeffrey estimates the probability of two individuals’ DNA profiles matching in the most commonly used tests at one in a billion.
小题1:According to the text, DNA testing can NOT be used in _______ .

A．doing criminal investigations	B．deciding faraily law
C．clearmg wrongly accused people	D．telling twins apart

小题2:DNA samples are not popular with all the people because _______ .

A．the government in Britain establishes a criminal database

B．the US and Canada develop similar systems

C．DNA samples can be used to harm

a person’s privacy

D．DNA testing is too expensive and dangerous now

小题3:Where will you most probably find this article?

A．In a guidebook.	B．In a storybook.
C．In a science fiction.	D．In a scientific magazine.

小题4:Which is the best title for the passage?

A．Discovery of DNA testing by Jeffery	B．Practice of DNA testing in court

Photographs are everywhere. They decorate the walls of homes and are used in stores for sales of different goods. The news is filled with pictures of fires, floods, and special events. Photos record the beauties of nature. They can also bring things close that are far away. Through photos, people can see wild animals, cities in foreign lands, and even the stars in outer space. Photos also tell stories.
Reporting the news through photos is called photojournalism. At times photojourn

alists tell their stories through a single picture. At other times, they use a group of pictures to tell a story. Each picture is like a chapter in a book, which can do more than record the facts. It can also be a strong force for social change.
Jacob Riis was among the first photojournalists. He took pictures of parts of New York City where the poor lived. Riis believed that poverty caused crime, and he used photos to help him prove his point. A few years later, the photos of small children working in factories by Lewis Hine shocked the public. Hine’s pictures helped bring about laws to protect such children.
Hundreds of pictures may have to be taken in order to get one or two really good photos. It takes science to have the photo come out clearly and art to make a photo that has a good design and expresses feeling. Photojournalists make an actual record of what they see. A photo, however, can be both a work of art and an actual record. It can record an important event as a beautiful or exciting picture.
As historical and artistic documents(文献), photos can become more important over time. Today photojournali

sts still have their pictures appear in newspapers and magazines. They also publish them in books and on the Internet.
小题1:The underlined word “They” in the first paragraph refers to .

A．beauties

B．photos

C．goods

D．events

小题2:The photos of the small children by Hine show us that photos .

A．are also works of art	B．are popular ways of reporting news
C．often shock the public	D．can serve as a force for social change

小题3:What can we learn from the passage?

A．News with pictures is encouraging.

B．Photos help people improve their life.

C．News photos mean history in a sense.

D．People prefer reading news with pictures.

小题4:The text is mainly about .

A．telling the story through picture	B．decorating the walls of homes
C．publishing historical papers	D．expressing feeling through pictures

At one time, computers were expected largely to remove the need for paper copies of documents (文件) because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.
It is difficult to measure the quantity of paper used as a result of use of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. "I feel in my bones this revolution is causing more trees to be cut down," says Ted S

mith of the Earth Village Organization.
Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers.
Does all this mean environmental concerns (环境问题) have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. " I guess people believe that the problem is taken care of, because of recycling (回收利用) " said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity. The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.
小题1: The growing demand for paper in recent years is largely due to ________.

A．the rapid development of small businesses

B．the opening up of new markets

C．the printing of high quality copies

D．the increased use of the Internet

小题2:Environmentalists believe one possible way of dealing with the paper situation is ________.

A．to encourage printing more quality documents

B．to develop new printers using recycled paper

C．to find new materials for making paper

D．to plant more fast-growing trees

小题3:Hewlett-Packard Co. has decided to develop new technologies because _______.

A．people are concerned about the environment

B．printers in many offices are working overtime

C．small companies need more hard copies

D．they see a growing market for printers
