Targeting teens
But using the Web also makes teens a target. Posting too much personal information for those millions of cyber eyes to see can cause some big problems and can even invite a threat to your life.
As Mary learned, not everyone on the Internet is who he or she says they are. Adults will sometimes pose as other teens, posting fake photos and nice messages to gain trust. They use their fake identity to access the personal information of others, such as home address, phone number, or school name.
"That's not the most common scenario", says David Finkelhor, a sociology professor at the University of New Hampshire. "Only 3 percent of teens aged 10 to 18 who use the Internet report being asked to meet offline. But the danger is real.
Safety measures
Mary's My Space profile is set to "private", which means that only the people she adds under the "friend" category can access her page. She also doesn't have any pictures of herself on her site. The only self-identifying material she has posted is her name, grade, and a list of hobbies.
"People can only add me if they know my last name or my e-mail, "Mary says. " I don't want random people to see my profile. I just go online to talk to my friends."
Stay safe and have fun online
Experts say almost 90 percent of U.S. Teens are online. But not everyone knows how to surf the Web in a smart way. With these tips, you can have fun, stay safe, and avoid embarrassment!
Pick a safe password. Make sure your password is something that other people won't be able to guess. Use numbers in between letters. "spar123ky" is better than "sparky 123."
Pick a safe username. Make sure yours doesn't say too much about you, "Happygirl13" is better than "AliceWaters13." Don't include your name, age, or where you are from. Never tell a stranger your name, school, address, age, birthday, phone number, or friends' names.
56.Who is most likely to be a victim online?
A.A liar.      B.A teenager.       C.A stranger.      D.An honest person.
57.In Mary's opinion, _________.
A.one shouldn't trust everyone online B.one shouldn't trust anyone online
C.there are many liars online      D.a(chǎn)ll people online pretend to be others
58.One of the safety measures mentioned in the passage is that _________.
A.one should not chat with strangers
B.one should not post his or her photos online
C.one should tell his parents about strange information
D.one should keep his web as a secret
59.Why are numbers used when we pick a safe password?
A.Numbers are easy to write.
B.Using numbers are cool online.
C.The safe password is more unlikely to be guessed.
D.Numbers are popular online.

As you move around your home, take a good look at the things you have. It is likely that your living room will have a television set and a video, and your kitchen a washing machine and a microwave oven. Your bedroom drawers will be filled with almost three times as many clothes as you need. You almost certainly own a car and possibly a home computer, holiday abroad at least once a year and eat out at least once a week.
Now, perhaps, more than ever before, people are wondering what life is all about, and what it is for. Seeking material success is beginning to trouble large numbers of people around the world. They feel that the long?hours work culture to make more money to buy more things is eating up their lives, leaving them very little time or energy for family or pastimes. Many are turning to other ways of l
iving and downshifting is one of them.
Six percent of workers in Britain took the decision to downshift last year. One couple who downshifted is Daniel and Liz. They used to work in central London. He was a newspaper reporter and she used to work for an international bank. They would go to work by train every day from their large house in the suburbs(郊區(qū)), leaving their two children with a nanny(保姆). Most evenings Daniel wouldn't get home until eight or nine o'clock, and nearly twice a month he would have to fly to New York for meetings. They both earned a large amount of money but began to feel that life was passing them by.
Nowadays, they run a farm in the mountains of Wales. “I always wanted to have a farm here,” says Daniel, “and we took almost a year to make the decision to downshift. It's taken some getting used to, but it's been worth it. We have to think twice now about spending money on car repairs and we no longer have any holidays. However, I think it's made us stronger as a family, and the children are a lot happier.”
Liz, however, is not quite sure. “I used to enjoy my job, even though it was hard work and long hours. I'm not really a country girl, but I suppose I'm gradually getting used to looking after the animals. One thing I do like, though, is being able to see more of my children. My advice for other people wanting to do the same is not to think about ittoo much or you might not do it at all.”
1.What do the first two paragraphs tell us?
A.People seldom work long hours to make money.
B.People hardly buy more things than necessary.
C.People are sure everything they own is in the right place.
D.People realise there is more to life than just making money. 
2.When Daniel was a reporter he  ________ .
A.lived in central London      B.disliked his job        
C.missed his children        D.was well paid 
3.Daniel and Liz both agree that the move to the farm  ________.
A.was easy to organize        B.has improved family life        
C.was extremely expensive      D.has been a total success 
4.What does the underlined “it” in the last paragraph refer to?
A.Child?caring.    B.Liz's advice.       C.Downshifting.     D.Liz's job.
5.The underlined word “_________downshifting” in the second paragraph means  ________ .
A.repairing your car by yourself        
B.spending money carefully        
C.moving out to the countryside to live a simpler and better life        
D.living in a big house in the suburbs and dining out once a week

The Book of Life
So far,scientists have named about 1.8 million living species(物種),and that’s just a small number of what probably exists on Earth.With so many plants,animals,and other living things covering the planet,it can be tough to figure out what type of grass is growing by the roadside or what kind of bird just flew by.
A soon-to-be-started Web site might help.An international team of researchers has announced the creation of Web-based Encyclopedia(百科全書(shū)) of Life(EoL).The project aims to list every species on Earth in a single,easy-to-use reference guide.
To get the encyclopedia started,the creators will use information from scientific databases(數(shù)據(jù)庫(kù)) that already exist.And eventually,in special sections of the site,non-scientists with specialized knowledge will come to help.Bird-watchers,for example,will be able to input what birds they’ve seen and where.To make sure the encyclopedia is accurate,scientists will review much of the information added to it.
As the EoL develops,you might find it useful for school projects.The site will feature(以……為特色)_____special pages for kids who are studying ecosystems in their neighborhoods.Another convenient feature of the EoL is that you’ll be able to pick the level of detail you want to see to match your interests,age,and knowledge.
It now takes years for scientists to collect all the data they need to describe and analyze species.The creators of the Encyclopedia of Life hope that their new fool will speed up that process.
小題1:The Web based EoL aims to _______.
A.find out what covers the earth
B.list all living things on Earth
C.work out the number of birds
D.save the existing plants
小題2:One characteristic of the EoL is that _______.
A.it is run by school students
B.it focuses on different types of grass
C.it provides different levels of information
D.it allows non-scientists to review its data
小題3:In the last paragraph,“that process”means _______.
A.a(chǎn)nalyzing speciesB.creating a new tool
C.collecting dataD.describing species

         Men usually want to have their own way. They want to think and act as they like. No one, however, can have his own way all the time. A man cannot live in society without considering the interests(利益) of others as well as his own interests. “Society” means a group of people with the same laws and the same way of life. People in society may make their own decisions, but these decisions ought not to be unjust(不公平) or harmful to others. One man’s decisions may so easily harm another person. For example, a motorist may be in a hurry to get to a friend’s house. He sets out, driving at full speed like a competitor in a motor race. There are other vehicles and also pedestrians (行人) on the road. Suddenly there is a crash. There are screams and confusion. One careless motorist has struck another car. The collision(碰撞) has injured two of the passengers and killed the third. Too many road accidents happen through the thoughtlessness of selfish drivers.
We have governments, the police and the law courts to prevent or to punish such criminal acts. But in addition, all men ought to observe certain rules of conduct. Every man ought to behave with consideration for other men. He ought not to steal, cheat, or destroy the property(財(cái)產(chǎn)) of others. There is no place of this sort of behavior in a civilized society.
51. A man cannot have his own way all the time because________.
A. he may have no interest in other people
B. he has to share the same interest with the people in the same society
C. his decisions are always unjust            D. his decisions always harm other people
52. According to the passage, people in a civilized society should usually______.
A. be honest to each other                         B. be cautions in doing everything
C. behave in a responsible way                 D. punish criminal acts
53. The purpose of this passage is to_________.
A. tell people how to behave in society  
B. illustrate the importance of laws
C. teach people how to prevent criminal acts
D. persuade people not to make their own decisions
54. It is implied that there will be fewer road accidents if_______.
A. the drivers are more considerate(體貼的) of other people
B. there are fewer cars or walkers in the street
C. the motorists are not always in a hurry

Every artist knows in his heart that he is saying something to the public. Not only does he want to say it well, but he wants it to be something which has not been said before. He hopes the public will listen and understand what he wants to teach them, and what he wants them to learn from him.
What visual artists like painters want to teach is easy to make out but difficult to explain, because painters translate their experience into shapes and colors, not words. They seem to feel that a certain selection of shapes and colors, out of countless billions possible, is exceptionally interesting for them and worth showing to us. Without their work we should never have noticed these particular shapes and colors, or have felt the delight which they brought to the artist.
Most artists take their shapes and colors from the world of nature and from human bodies in motion (運(yùn)動(dòng)) and at rest; their choices show that these aspects (方面) of the world are worth looking at, and that they contain beautiful sights. Modern artists might say that they only choose subjects that provide an interesting pattern, and that there is nothing more in it. Yet they do not choose entirely without reference to the character of their subjects.
If one painter chooses to paint a decaying (腐爛) leg and another a lake in moonlight, each of them is directing out attention to a certain aspect of the world. Each painter is telling us something, showing us something, explaining something – all of which means that he is trying to teach us.
50.According to the passage, all of the following is true except_________.
A.An artist wants to show something meaningful
B.An artist hopes that the public will understand and learn from him
C.An artist asks the public to believe what he says in his work
D.An artist intends to present something that has not been said before
51.It is hard to explain what a painter is saying, because           .
A.a(chǎn) painter uses unusual words and phrases
B.a(chǎn) painter uses shapes and colors instead of words
C.most painters do not express themselves well
D.many painters do not say anything
52.Modern artists might say their choice of subject         .
A.only provides interesting patterns
B.carries a message to the public
C.has no pattern or form
D.teaches the public important truths
53.The underlined word “exceptionally” in the 2nd paragraph probably means        .
A.entirely               B.generally             C.especially            D.usually
