Cell Phones Are the New Cigarettes
When you get in your car, you reach for it.When you’re at work, you take a break to have a moment alone with it.When you get into a lift, you play with it.
Cigarettes? Cup of coffee? No, it’s the third most addictive thing in modern life, the cell phone.And experts say it is becoming more difficult for many people to curbtheir longing to hug  it more tightly than most of their personal relationships.
With its shiny surface, its smooth and satisfying touch, its air of complexity, the cell phone  connects us to the world even as it disconnects us from people three feet away.In just the past  couple of years, the cell phone has challenged individuals, employers, phone makers and  counselors(顧問(wèn))in ways its inventors in the late 1940s never imagined.
The costs are becoming even more evident, and I don’t mean just the monthly bill.Dr.Chris  Knippers, a counselor at the Betty Ford Center in Southern California, reports that the overuse of  cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on-one personal contact, and an escape from reality.
Sounds extreme, but we’ve all witnessed the evidence: The person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him.
Is it just rude, or is it a kind of unhealthiness? And pardon me, but how is this improving the quality of life?
Jim Williams, an industrial sociologist based in Massachusetts, notes that cell-phone addiction is part of a set of symptoms in a widening gulf of personal separation.He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with.Despite the growing use of phones, e-mail and instant messaging, in other words, Williams says studies show that we don’t have as many friends as our parents. “Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends,” he says.
If the cell phone has truly had these effects, it’s because it has become very widespread.Consider that in 1987, there were only 1 million cell phones in use.Today, something like 300 million Americans carry them.They far outnumber wired phones in the United States.
小題1:Which of the following best explains the title of the passage?
A.Cell phone users smoke less than they used to.
B.Cell phones have become as addictive as cigarettes.
C.More people use cell phones than smoke cigarettes.
D.Using cell phone is just as cool as smoking cigarettes.
小題2:The underlined word “curb” in Paragraph 2 means ____.
A.rescueB.ignoreC.developD.control
小題3:The example of a woman talking on the phone in the car supports the idea that           
A.women use cell phones more often than men
B.talking on the phone while driving is dangerous
C.cell phones do not necessarily bring people together
D.cell phones make one-on-one personal contact easy

小題1:B

When people talk of a virus these days, chances are that they are talking about computer virus that have the power wipe out all the valuable work people may have stored in their computers. Imagine, the virus has the power to make military systems, giant banks, airports, hospitals and traffic system come to stop!
What does a computer virus do? It targets electronic objects that are programmed. The virus spreads through connections between these electronic objects. For virus spreading experts, e-mail is a favorite method of sending their destructive (破壞性的) weapon.
But scientists warn that this is not the worst that can happen. There is more. People are also connected through phones. The next virus may actually target mobile phones, especially those that are programmed to do many tasks apart from just communicating. It would then be easy for a virus to infect those programs and create major disorder.
For example, these virus may have the power to record your phone conversations and make others hear them. They create problems with your electronic money accounts, or they could create a mountain of telephone bills for calls you never made. And that would be a disaster. A report on this was published in the New Scientist recently. 
One way out would be to have simpler phones with not so many different functions. This would mean there would mean there would be fewer programs for the virus to attack. But mobile phone producers are in a fix. People on longer want an electronic item to perform just one task. They want more and more functions added. That would mean more software programs to make the mobile phone perform all those functions. And that means the possibility of more viruses.
小題1:It can be inferred from the passage that ______.
A.computer viruses are not so as destructive as mobile phone viruses
B.people should be careful when receiving e-mails
C.people find it difficult to use electronic equipment correctly
D.having electronic money accounts brings people a lot of convenience
小題2:Which of the following shows that your mobile phone is infected with a virus?
A.You can’t hear the person who answers the phone clearly
B.You can’t send e-mails with your mobile phone
C.your phone bill increases for unknown reasons
D.You can hear other people’s phone conversations
小題3:What does the underlined sentence in the last paragraph mean?
A.Mobile phone producers have made no progress.
B.Mobile phone producers are proud of their products.
C.Mobile phone producers are faced with a difficult situation.
D.Mobile phone producers refused to fight against virus.
小題4:For whom is the passage written?
A.Government officialsB.Virus spreading experts
C.Electronic scientistsD.Mobile phone users

Elephants have four distinct personalities that help their herd survive in the African bush, scientists have found. 
With their grey skin, mournful eyes and slow heavy pace, you could be forgiven for thinking elephants are uniformly melancholy(憂郁的) creatures. But scientists have now discovered the largest living land animals have personalities to match their size.
In a new study of African elephants, researchers have identified four distinct characters that are common in a herd – the leaders, the gentle giants, the playful rogues(小淘氣) and the reliable plodders (辛勤工作的人).
Each of the types has developed to help the giant mammals survive in their harsh environment and is almost unique in the animal kingdom, according to the scientists.
Professor Phyllis Lee and her colleague Cynthia Moss studied a herd of elephants in the Amboseli National Park in Kenya known as the EB family — famous for their matriarch Echo before she died in 2009.
Using data collected over 38 years of watching this group, the researchers analyzed them for 26 types of behavior and found four personality features tended to emerge.
The strongest personality to emerge was that of the leader. Unlike other animals, where leadership tends to be won by the most dominant and aggressive individual, the elephants instead respected intelligence and problem solving in their leader. Echo, the matriarch and oldest in the group, her daughter Enid, and Ella, the second oldest female, all emerged as leaders.
The playful elephants tended to be younger but were more curious and active. Eudora, a 40-year-old female in the herd, seemed to be the most playful, consistently showing this feature throughout her life while playfulness in some of the other elephants declined with age.
Gentle elephants, which included two 27-year-old females Eleanor and Eliot, touched and rubbed against others more than the others.
Those that were reliable tended to be those that were most consistent at making good decisions, helped to care for infants in the herd and were calm when faced with threats. Echo and her youngest daughter Ebony seemed to be the most reliable.
Professor Lee said that elephants with these features tended to be the most socially integrated in the group while those who tended to be less reliable and pushy were more likely to split from the herd.
小題1:From the passage we get to know that ________.
A.the researchers reached their conclusion by analyzing the data
B.the research centered on the 26 types of behavior of the matriarch
C.the scientists conducted the research by comparing elephants with other animals
D.professor Phyllis Lee and her colleague spent nearly 38 years tracking the herd
小題2:According to the new findings of the scientists, ________.
A.playfulness of an elephant will always decline with age
B.those elephants which are caring and wise are most reliable
C.each elephant can be matched with only one of the four personalities
D.once becoming a member of a herd, an elephant will never split from it
小題3:In the EB family Echo and Eudora are ________.
A.mother and daughterB.two oldest females
C.the gentlest onesD.leader and member

Dear Victor:
I am a college student. Nowadays games on the net are very popular with college students. Some of my roommates are very interested in them. They not only play games in their free time, but also keep talking about them at night when lights are off, and they regard games as part of life. I’ve begged(乞求) them to give it up, but they wouldn’t listen to me. It has become a rather big problem. Should I report it to our teachers or do something else?
Ted,
Dear Ted:
Drop it. Your roommates, as grown-ups, can do whatever they want with their time so long as it doesn’t break school rules or violate(防礙) other people’s interests.
Playing perhaps gives these students relaxation(放松) from hard study. If they play too often, have little time to study, and they will reap what they have sown, but you will not. Reporting to the teachers would only harm your good name in your dormitory(宿舍). However you have rights to ask your roommates to be quiet when you need sleep. If they aren’t angry with you, they will stop talking. But be polite and friendly. Perhaps, in return, join them in a game or two.

Two Christmas traditions have come under attack in recent years from environmentalists: Christmas cards and Christmas trees.
Paper cards are seen as wasteful and, for some people, going card-free is another way of going green. They also argue that in a world of e-mail, Skype, Facebook and Twitter, people are in touch all the time anyway; they no longer need the yearly card that connects them with long lost friends. If you want to send Christmas greetings, there are free e-cards, which get the job done with no postage or wasted paper.
However, especially for people who didn’t grow up with e-mail, there is something missing from a Christmas e-mail. The first Christmas cards appeared in London in 1843 and were designed by the same man who had introduced the world’s first postage stamp three years earlier. His name was Sir Henry Cole.
They rose in popularity throughout the 20th century. Many people sent cards that were sold for charity. The most famous of these are the ones sold for UNICEF. In the UK this year, in the three weeks before Christmas, the post office expects to handle 100 million cards every day. Environmental awareness also means that nowadays many people recycle their cards; this helps raise money to plant more trees, as well as recreating more paper.
When we think of trees at Christmas, there is one that immediately springs(躍入)mind---the evergreen tree that people decorate with ornaments and place their presents under. The custom dates back almost a thousand years to Germany. Nowadays 33 to 36 million Christmas trees are produced in America and 50 to 60 million in Europe each year. Some trees are sold live with roots and soil so people can plant them later and reuse them next year.
Some people prefer artificial trees as they are reusable and much cheaper than their natural alternative. However, environmentalists point out that they are made from petroleum (石油) products and so have many pollution issues.
小題1:What is the main idea of the article?
A.To introduce the history of two typical Christmas traditions.
B.To explain the debate about some Christmas traditions.
C.To analyze how two Christmas traditions grew in popularity.
D.To point out the problems caused by celebrating Christmas.
小題2:What does the underlined word “They” in the fourth paragraph probably mean?
A.Many peopleB.Christmas e-mailsC.Postage stampsD.Christmas cards
小題3:Some people suggest getting rid of paper cards because     .
a. they cannot be recycled         b. they are not environmentally friendly
c. they are mostly sold for charity  d. the e-cards have many advantages over them
e. they are not as necessary as they used to be for people
A.a(chǎn), b, dB.a(chǎn), c, dC.b, d, eD.b, c, e
小題4:What can we conclude from the article?
A.The first Christmas cards were designed earlier than the world’s first stamps.
B.This year has seen a dramatic drop in Christmas card sales.
C.Environmentalists advise people to buy cards that are sold for charity.
D.Growing environmental awareness is encouraging people to recycle their cards.
小題5:Which of the following statements in TRUE according to the article?
A.There is always a wider Christmas tree market in America than in Europe.
B.The custom of decorating Christmas trees first appeared in Britain.
C.Some people prefer to buy live trees that can be reused next year.
D.Artificial trees are better than natural ones in all aspects.

A student walks into his first class and realizes he forgot all about the midterm exam. He knows he needs to bring his grades up, and getting a zero will make it nearly impossible. He quickly jots down some notes and shoves them under his lap hoping it will help him pass. Cheating is a major concern in all academic environments. Students are creating new and more outrageous(令人吃驚的) ways of cheating every day; some claim that certain accounts of cheating can be justified, but overall it can always be prevented.
Cheating has been around forever, and millions of ways to cheat have been fashioned. Copying homework and cheat sheets are some of the most basic ways students in all education levels have cheated. Some students think nothing about writing a few answers on their hand, in a gum wrapper, or boldly using a study guide to cheat. Desperate students have even gone as far as to steal the test or scan in bottle wrappers and put answers into the nutrition label. The internet has now become available in almost every location. Computers can be accessed at school, at home, and now even on cell phones. This opens a doorway for even more methods of cheating to be born.
There are countless opinions on whether or not cheating can be justified. The truth is this behavior will always be a matter of opinion with each scenario of cheating. Students often rationalize their cheating by claiming they forgot to look over the material or did not understand what the teacher or professor was saying. Some may counter these arguments by saying that the student could have set reminders or asked the teacher to explain the material before the day of the test. Some other reasons students believe cheating is justified are their heavy workloads and trying to find time for school, sports, friends, and family. This may be true in certain instances, however, all students have these problems, and it is unfair to the students refrain(制止) from cheating when the student who is dishonest receives a better grade. The majority of students who think cheating is acceptable may believe the reason for this is that sometimes students are unaware they are cheating, there is not enough time given for assignments, or that the information is too much for the course.
It may be difficult to accomplish, but cheating can be prevented. Teachers and professors have tried many options to stop cheating. These options can range anywhere from simply spreading test-takers out in a room, to expelling(驅(qū)逐) a student, which will most likely hindertheir plans of getting into another college. One simple way to fix the problem is to scold the student when caught. They may be so scared or embarrassed that they never do it again. This is a risky way to prevent cheating in some cases, however, because it can possibly damage self-esteem. Another simple way to avoid cheating is to create many different kinds of the same test. This prohibits students from getting the answers off of a neighbor's test, but students still have the option of using other cheating tactics.
There may be a million ways to cheat and get away with it, but there are few times, if any, that it is justified. Cheating never has to be a necessity and is never worth compromising morals and losing years worth of working towards a degree. This problem is spreading throughout America; with everyone's help, it can be stopped.
小題1:Which is the best title of this passage?
A.To cheat or not to cheatB.Show your opinion on cheating
C.Debates on cheatingD.Different ways of cheating
小題2:The second paragraph mainly tells us that ________.
A.cheating through the Internet is the most basic way
B.students who cheat in exams are cleverer
C.millions of ways to cheat have been fashioned
D.students cheat in exams to score better grades
小題3:The reason that is given by most students who think cheating is understandable is that ________.
A.they don’t understand their teachers’ words
B.they bury themselves in a lot of homework
C.they don’t have enough time to complete the study tasks
D.they forget to look over the material
小題4:What is the disadvantage of scolding the cheating students according to the passage?
A.They may continue to cheat next time.
B.They may be hurt mentally.
C.They may use other cheating tactics.
D.They may get on badly with their teachers.
小題5:What is the author’s attitude towards cheating?
A.It is reasonableB.It is necessary

Sea lions and seals may swim in cold ocean water, but even they get chilly sometimes. Seeing an injured seal wrapped in a blanket at a marine(海的) mammal center gave Haley Humes and Hayley Jeffries an idea for a special Girl Scout project. They decided to make blankets to keep injured animals warm. They would give these blankets to the Pacific Marine Mammal Center in Laguna Beach, California.
“We knew we wanted to help animals,” Haley said. “We went to the center to ask questions about what they needed. They don’t have a heated floor, and all the babies crowded together to stay warm.”
Friends since kindergarten, Haley and Hayley made 12 blankets to keep the Marine Mammal Center’s seals and sea lions warm. Using fun images like Winnie-the-Pooh, the girls took two hours to make each blanket. The first sea lion to test out a blanket looked pretty in pink.
“It was a sick baby and really liked it,” Haley said. “It curled up in it right away.”
“The blankets are beautiful and the animals love them!” said the Mammal Center’s Michele Hunter. “It’s nice to see children taking pride in their work and doing something to help animals.”
During the project, the girls took dozens of pictures for the PowerPoint presentations they gave to Girl Scout leaders. Those presentations helped Haley and Hayley raise $250 to buy additional supplies the center needed.
This was the first project the girls ever worked on and took months to plan and carry out.
“I learned that in order to make something happen, you have to take it slowly and step by step,” Hayley said. Just as important, the girls discovered that two people really can make a difference. “Knowing you’re making a difference……with these animals is amazing,” Haley said. “It was like the animals became my new friends.”
The Pacific Marine Mammal Center cares for sea lions and seals, as well as for other marine mammals. Since opening in 1971,the center has saved more than 5,000 injured marine mammals.
小題1:          What does the underlined word“ chilly” in Paragraph 1 mean?
A.Sick. B.Cold.C.Afraid. D.Bored.
小題2:          When Haley and Hayley saw an injured seal wrapped in a blanket, they_____.
A.decided to help animalsB.a(chǎn)sked Girl Scout for help
C.went to the animal center to work.D.called on others to protect animals
小題3:          What can we learn about Haley and Hayley from the text?
A.They raised $2,500 for the Mammal Center.
B.They made 120 blankets by themselves.
C.It took them an hour to make a blanket.
D.They felt great about what they did.
小題4:          Which of the following words can best describe the work of Haley and Hayley?
A.Difficult.B.Successful.C.Experimental.D.Dangerous.
小題5:          According to the text, the Mammal Center_____.
A.has a history of about 40 years
B.has an advanced heating system
C.has saved ten thousand animals so far
D.protects both land and marine mammals
