I am sure that everybody in his/her life has used computers. Nowadays you can feel their presence everywhere at home,at school,at work and they certainly make life easier.On the other hand,there are people who can’t work with them.
Anyway,I believe their presence is a good thing. Life with them seems easier, less difficult and more comfortable You can use them to choose your meal,to withdraw your money, and also save your time,because these operations are all controlled by computers. Therefore you can hardly imagine the modern world without them;the whole planet seems to be one big computer society.
Nevertheless,problems can often appear in this area, too.To have a computer means you have to be quite well-off and have the necessary skills to use it.However,think about questions like “Are computers so available for everyone, or rich and poor people,for people from villages and people from cities. Aren’t they too expensive?Is everyone able to learn how to use them and not everyone has the chance to access and work with them,how could everything in the future be dependent on them?”Therefore,I think our society will be split into two parts.One part will work with them and enjoy the benefits that computers can bring and the other part will be pushed out and will actually be far behind the other group.
Another question that bothers me is,on the one hand,computers are important  and good things in our life,but they aren’t everything.They are good as a help at school,quite often as entertainment,especially for young people,as an necessary tool to help in research etc,but I think we shouldn’t be so dependent on them,because computers are only machines and machines can’t feel anything be human and sympathetic,and every action performed by computer can be interfered with another person,which could cause these machines to crash or work badly.
In conclusion,I would like to say I am not against computers.I use computers,too,but people should be wary all the time.
小題1:By saying “wary”(In the last paragraph),the writer is trying to say “People should_______.
A.be strongly for the use of computers because of its convenience
B.be careful with computers that will also cause problems
C.master more necessary computer skills
D.not do something that causes computers to work badly

A.a(chǎn)sking questions for people to think about

A.to encourage us to use computers in our society

We like to consider ourselves the superior race, and we are. It’s true that we are getting to know more and more, and we actually live in “the information age”. Our human vanity(虛榮心) makes us believe that we really have to know everything! Surprisingly, we do not have this ability. The question “what is happening in the Bermuda Triangle” is the very proof.
Where is the Bermuda Triangle located? The mysterious triangle is believed to be situated between Florida, Bermuda and Puerto Rico, where too many unusual events have happened.
On December the 5th 1945, five U.S. military planes took off from Florida on a clear day only to disappear over Bermuda. Furthermore, some other disappearances took place; in 1947, an American C54 plane simply disappeared at 100 miles from Bermuda; at 80 miles, a Star Tiger plane disappeared in 1948.
Even Columbus had trouble in Bermuda. Some of his journals were about the strange happenings there: “the waters are changing their colors” and “compasses are going wild”.
Maybe it’s why it is called the Devil’s triangle or the Atlantic cemetery.
Many hypotheses were stated in order to explain the strange events. In spite of these attempts, the mystery of the Bermuda Triangle remains unsolved.
Some people get to say that maybe aliens are involved in it. Other imaginative scientists relate the happenings in Bermuda to Einstein’s theory, saying that the missing ships and planes are translated to another dimension of space and time and taken into another world.
Maybe we will just have to wait to go to Heaven and ask the One who made it. The answer will surely be a satisfying one!
小題1:The writer may probably think that______.
A.humans have to and can know everything strange
B.the missing ships are taken into another world
C.humans can know more in “the information age”
D.God created the mystery of the Bermuda Triangle
小題2: Columbus’ journals told us that in Bermuda _______.
A.a(chǎn)n American C54 plane disappeared

C.the compasses were lost
D.a(chǎn) cemetery was found

For a writer, there is hardly any greater honor than winning the Nobel Prize for literature.
And for a woman writer, claiming the prize is even harder, for only eight women once won it. Austria’s Elfriede Jelinek is the ninth and the first since 1996.
The Stockholm-based Swedish Academy announced last Thursday that Jelinek won this year’s Nobel Prize in literature. She is recognized for her socially critical(批判的) novels and plays.
Jelinek, 57, made her literary debut (初次露面) in 1967. She has written plays, novels and poetry. She is best known for her autobiographical 1983 novel “The Piano Teacher”, made into a movie in 2001.
The basic theme of her work is the inability of women to live as people beyond the roles and personalities traditionally expected of them. Her characters struggle to lead lives not normally acceptable in society. “The nature of Jelinek’s texts is often hard to define. They shift between prose(散文) and poetry and songs, they contain theatrical scenes and film script,” said the academy.
The Nobel Prize was founded by Swedish inventor Alfred Nobel. Nobel died in 1896 and left his fortune of about US $920 million to a fund to honor people who have helped other human beings. This year each prize is worth US $13 million.
小題1: The underlined word “them” in the last second paragraph refers to _______.
A.rolesB.peopleC.textsD.women
小題2:Elfrede Jelinek won the Nobel Prize just because _______.
A.she was an Austrian woman writer
B.she wrote socially critical novels and plays
C.her novel “The Piano Teacher” was made into a movie
D.the nature of her texts is hard to define.
小題3: Which of the following about the Nobel Prize is TRUE?
A.It is harder for a woman writer to win than a man writer.
B.The total prize every year was $920 million.
C.Women writers were not awarded until 1996.
D.Only eight women writers won the prize since 1996.
小題4:This passage is most likely taken from _______.
A.a(chǎn) travel magazineB.a(chǎn) history bookC.a(chǎn) newspaperD.a(chǎn)n advertisement

Many Americans take their summer vacations in August. President Obama and his family are among them. This August the first family visited the Florida Gulf Coast. The president wants to promote tourism in the area after the BP oil spill (漏油). The first family took a ten-day vacation on Martha’s Vineyard, an island off the coast of Massachusetts.
Martha’s Vineyard is known for the sailing, sunsets and its tall cliffs overlooking the Atlantic Ocean. The island is about 13 kilometers off the coast and is less than 260 square kilometers. Homes designed like those of earlier times line the streets of Edgartown, Oak Bluffs and Vineyard Haven. These are the major towns on Martha’s Vineyard.
For most of the year, the population of Martha’s Vineyard is about 15 000. In summer, more than 100 000 people crowd the island. In addition to the Obamas, you might see some Hollywood stars and other rich and famous people. Many visitors return year after year.
During warm weather the Vineyard is a good place for many different activities. People can play golf or catch fish. They can ride in sailboats or motor boats. They can waterski and swim. They can take quiet walks along sandy beaches and among the thick green trees.
One of the popular places for families with children is the Flying Horses Carousel in Oak Bluffs. It is the oldest continually operated merry-go-round ride in the United States. The colorful wood horses that turn in a circle were created in 1876. One of the best places for children to swim is the Joseph A. Sylvia state beach. The water there is warmer and calmer. Families also enjoy the Felix Neck Wildlife Sanctuary where they can observe much of the island wildlife.
Visitors watch the sunsets sitting on the beach and on rocks in the fishing village of Menemsha. As the sun goes down in the sky it paints yellow, red, and other colors on the clouds. Fishing boats rise and fall with the waves. Bells sound to help guide the boats to land as darkness covers the water.
Historians say British mapmaker Bartholomew Gosnold first made a map of the island for the rulers of England in 1602. Gosnold named the island to honor his baby daughter, Martha. The Vineyard part of the name came from the many wild grape vines Gosnold found on the island. Later, King Charles of England gave the island to businessman Thomas Mayhew of the Massachusetts Bay Colony, whose son established the first European settlement on the island in 1642. By the middle of the nineteenth century, ships from the American mainland began bringing visitors to the island. Big hotels were built near the edge of the water. Martha’s Vineyard was on its way to becoming the visitors center that it is today.
小題1:.
We can infer that ______.
A.the BP oil spill has a negative effect on the tourism along the Florida Gulf Coast
B.the BP oil spill has contributed to the tourism along the Florida Gulf Coast
C.President Obama went to the Florida Gulf Coast to deal with the BP oil spill

It takes two to duet (二重唱), and one question for scientists is how these coordinated (協(xié)調(diào)的) performances arise — in birds. Are they the result of cooperation, a way in which one pair signals to others that they’ve got it together? Or are they the result of conflict, evolving to avoid one partner’s song interfering with the other’s?
A study of duetting in Peruvian warbling antbirds(蟻鳥(niǎo)) suggests that it might be a little of both, and that context is everything. Joseph A. Tobias and Nathalie Seddon of the University of Oxford show in Current Biology that sexual conflict can cause the female of a pair that normally cooperates to “jam” the male’s song by singing over it.
The researchers exposed antbird pairs to recorded songs of other antbirds and monitored the songs the pairs produced. In one experiment, they played the songs of an intruding pair. In this case, the resident pair “both are likely to lose their territory, so both should cooperate,” Dr. Tobias said. And they do. They produce a coordinated duet that in effect tells the intruders to keep away.
But when the researchers played the song of a single female, the pair behaved differently. “You’d expect the resident female to be highly motivated to defend her position in the partnership,” Dr. Tobias said. And that’s what occurs. The male sings its heart out, flirting(調(diào)情) with the single female, and the female of the pair does its best to interfere with the song by singing over it, apparently to make her mate less attractive to the other female.
“It’s clear that the male doesn’t like what she’s doing,” Dr. Tobias said. The behavior “breaks up what is otherwise a very cooperative situation into a more complicated signal,” he added.
It’s the first evidence of this kind of signal jamming among pairs, Dr. Tobias said.
And in that it leads the male to alter its song to avoid the female’s interfering notes, it shows that this kind of conflict could, over a long period, drive the evolution of coordinated song.
小題1:
What is the key factor of antbirds’ duet?
A.Their cooperation.B.Their conflict.
C.The context.D.Their instinct.
小題2:
How did the researchers conduct the experiment?
A.They put the antbird pairs back to nature and observe them.
B.They played different recorded songs of other antbirds.
C.They put an antbird to the other’s territory and observed.
D.They played the songs of an intruding pair.
小題3:
Why did the female bird sing according to Paragraph 4?
A.It wanted to show its singing talent to the partner.
B.It aimed at keeping the partnership with the male.
C.It wanted to frighten the other females.
D.It wanted to make her mate more attractive.
小題4:

Do you know how to prepare for and survive a major earthquake? According to Department of Conservation scientists, it is important to have the right answer to that question.
How to Be Prepared
Electricity, water, gas and telephones may not be working after an earthquake. The police and fire departments are likely to be tied up. You should be prepared to fend for yourself at least three days,preferably for a week. You’ll need food, water and so on. It’s also a good idea to decide ahead of time how and where your family will reunite if separated during a quake. You might choose an out-of-the-area friend or relative that family members can call to check on you.
________
If you’re indoors, stay there. Get under a desk or table. The kitchen is a particularly dangerous spot. If you’re in an office building, stay away from windows and outside walls and do not use the elevator. If you’re outside, get into the open. Stay clear of buildings, power lines or anything else that could fall on you. If you’re driving, move the car out of traffic and stop. Avoid parking under or on bridges or overpasses.
After an Earthquake
Check for fire. If you smell gas, shut off the main gas valve(閥). If there’s sign of damage to electricial wiring, shut off the power at the control box. If the phone is working, only use it in case of emergency(緊急情況). Avoid driving if possible to keep the streets clear for emergency vehicles. Be careful that things may fall out of cupboards when the door is opened, and also that chimneys can be weakened and fall with just a touch. Listen to the radio for important information and instructions. Remember that aftershocks, sometimes large enough to cause damage in their own right, generally follow large quakes. If you leave home, leave a message telling your friends and family your location.

When it comes to protecting the privacy of their children, U.S. parents give social networks a failing grade. According to a recent survey, three out of four parents believe social networks are not doing a good job of protecting kids’ online privacy.
The survey was conducted for Common Sense Media, a nonprofit organization devoted to helping families find the right way to deal withthe world of media and technology.
Ninety-two percent of parents said they are concerned that children share too much information online, and 85 percent said they are more concerned about online privacy than they were five years ago. In other findings, Common Sense Media found that 68% of parents are not at all confident in search engines keeping their private information safe and secure and 71% of parents said the same about social networking sites.
The survey found a great deal of concern about the online geo-location services which find and show the exact position of somebody through the net. Ninety-one percent of parents said search engines and social networking sites should not be able to share the physical location of children with other companies unless the parents approve.
“The survey results present a clear divide between the industry’s view of privacy and the opinion of parents and kids,” Common Sense Media CEO and founder James Steyer said.
“American families are deeply worried about how their personal information is being used by technology and online companies, yet the companies appear to be keeping their heads deep in the sand,” Steyer said.
IT companies need to step up but parents, children, schools and government also need to do more, he said.
“Parents and kids have to educate themselves about how to protect their information,” he said. “Schools should teach all students and their parents about privacy protection.”
“And finally, policymakers have to update privacy policies for the 21st century,” he said. According to the survey, more than 60 percent of parents want the US Congress to update online privacy laws for children and teenagers.
小題1: What does the underlined part in Paragraph 6 mean?
A.Refusing to admit the problem.B.Refusing to work with others.
C.Trying to find a solution to the problemD.Trying to look deep into the problem.
小題2: According to James Steyer, the following organizations should make more contributions to protecting    
children’s online privacy except __________.
A.IT companiesB.GovernmentC.SchoolsD.Nonprofit Organizations
小題3:What can be inferred from the passage?
A.Parents are worried about social networks because they lead to the children’s failing grades.
B.Most US parents agree that the online geo-location services should be forbidden.
C.Most USparents will support a law that limits IT companies to using personal information.
D.US Congress has not yet passed any online privacy law for children and teenagers.
小題4: Which of the following may be the best title for the passage?
A.US Congress to Update Privacy Policies for 21st Century
B.Common Sense Media Warns Against Social Networks
C.US Parents Want Better Online Privacy Protection for Kids
D.Worry Grows for Problems Caused by Social Networks

Is early childhood education really necessary? Early childhood education primarily focuses on learning through playing to develop the child’s physical, sensory, communicational and social development. Early childhood education has become a concern of the government, who pushes poor children to be formally trained before they are old enough for Kindergarten.
There are good reasons for the government to push early childhood education.Studies have shown that orphaned children who did not receive good care and education become developmentally delayed causing failure in school, and even in life.Further studies show that poor children who take part in Head Start programs are more prepared for school, less likely to end up in Special Education classes, and are less likely to receive public help or go to jail.
There are also negative parts to putting a child in formal education programs too early.Time Magazine online explains that “the younger the child the less his chances of catching up with first-grade work.” I have personally witnessed many children of my generation who went to Head Start programs become frustrated and bored with school before they finished high school.Yet parents have been sure that the earlier the child starts school, the better off he or she is, so they push to start children earlier.
Actually while early formal education of poor children does show great gains in the early elementary years, studies also show that this head start is really a “false start”, as the gains are lost in middle and high school years.It seems that environment is a bigger factor on life’s success than early education.Head Start programs have not achieved its original goal in closing the achievement gap in poor and middle school children.Perhaps it is time to find other ways to close that gap.
小題1:The purpose of the government valuing the early childhood education is ________.
A.to develop the children’s communication
A.to give orphaned children good care and education
C.to get the children prepared for the kindergarten
D.to train the children formally and regularly
小題2:According to the studies, which of the following is True?
A.Children with good early education may have a rich life.
B.The orphaned children are usually unhappy in their life.
C.Children without early education can do well at school.
D.Head Start programs are helpful to the poor children.
小題3:The author’s attitude toward the early childhood education is _________.
A.puzzlingB.objectiveC.indifferentD.a(chǎn)pproving
小題4:The main idea of the last passage is that __________.
A.the early childhood education is very necessary
B.Head Start programs have helped the children a lot
C.environment is the most important to life’s success
D.better ways should be found to help the poor children
