Some games may improve kids’ hand-eye coordination and problem-solving skills. Games that require kids to actually move or manipulate（操縱）the game through their own physical movement can even get sedentary kids moving, though not as much as they could if they actually played outside or participated in sports or other outdoor acuities. Others, though, don’t have such benefits, and violent video games have been shown that they might increase kid’s aggressive behavior.
Like a lot of aspects of raising kids, when it comes to video games, the healthiest approach is actually self-control.
The American academy of Pediatrics(AAP) recommends that kids should spend no more than 2 hours each day on screen time, including watching TV or movies, or playing computer or video games. So consider setting limits at least that strict to keep game playing from affecting their schoolwork, household responsibilities, and the physical activity your son needs very day.
Make sure that he’s playing games which are suitable for his age group. All video games are rated and labeled by the Entertainment Software Rating Board. Steer clear of（避開）any rated “M” for mature. Those are for ages 17 and older and can contain heavy-duty violence, strong language, and sexual content.
Try to keep the video game console（游戲機控制板）in a common area of the house, not your son’s room. That way you can catch any inappropriate content in the games he’s playing, and he’ll be in a position to interact with others in the house while he’s playing.
Make sure your son has appealing alternatives, too, such as sports, activities, opportunities to socialize with peers; and downtime to be creative. If you continue to have concerns about his video game activity, talk with your doctor.

Imagine a classroom missing the one thing that’s long been considered a necessary part to reading and writing---paper. No notebooks, no textbooks, no test papers. Nor are there any pencils or pens, which always seems to run out of ink at the critical moment. A “paperless classroom” is what more and more schools are trying to achieve .
Students don’t do any handwriting in this class . Instead , they use palm size , or specially—designed computers. The teacher downloads texts from Internet libraries and sends them to every student’s personal computer. Having computers also means that students use the Web. They can look up information on any subject they’re studying from maths to social science.
High school teacher Judy Herrell in Florida, US, described how her class used the Web to learn about the war in Afghanistan over one year ago. We could touch every side of the country through different sites from the forest to refugee camps, she said .“Using a book that’s three or four years old is impossible.”And exams can go on line too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book. A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie—Sorrell in Kentucky,US, said she used to give about 900 pieces of paper each week to each student.
“Think about the money and trees we could save with the computers,”she said .But, with all this technology, there is always the risk that the machines will break down. So , in case of a power failure or technical problems, paper textbooks are still widely available for these hi—tech students.
小題1:What does the part of the last sentence in the first paragraph “run out of ink at the critical moment” mean ?
A．Pens may not write well at the critical moment.
B．Pens get lost easily , so you may not find them at the critical moment.
C．Pens may have little or no ink at the critical moment
D．Pens use ink, while pencils don’t.
小題2:The high school teacher, Judy Herrell, used the example of her class to show that ________.
A．the Web could take them everywhere
B．the Web taught them a lot.
C．the Web is a good tool for information.
D．the Web , better than the textbooks ,can give the latest and comprehensive information.
小題3:The paperless classroom will benefit _________ the most.
A．studentsB．teachersC．treesD．computers
小題4:What does the phrase in the last paragraph “break down ”mean ?
A．Break into piecesB．Stop workingC．Fall downD．Lose control

Now, there is a growing movement to pay the students in American schools---in some cases, even just for coming to class.
Students at one school in New Mexico can earn up to three hundred dollars a year for good attendance. In Baltimore, Maryland, high scores in state graduation tests can be worth more than one hundred dollars. And a New Jersey school system plans to pay students fifty dollars a week to attend after---school tutoring programs.
Schools that pay students can be found in more than one---fourth of the fifty states. Other schools pay students with food or other rewards.
Robert Schaefer is a public education director. He says paying students may improve performance in the short term, but students develop false expectations for the future. He sees a lack of long term planning in these programs because of the pressure on schools to raise test scores.
Public schools need to show improvement under the education reform law. Low---performing schools may lose their federal money; teachers and administrators(行政人員) may lose their jobs. Often these schools are in poor neighborhoods where getting students to go to school can be a continual problem.
Critics(評論家) say paying students sends a message that money is the only valuable reward. But some students say it makes school more exciting. And some teachers have reported getting more requests for extra help.
In two thousand four, the city schools in Coshocton, Ohio, launched a program. They wanted to see if paying elementary school students as much as one hundred dollars would help in passing the state exams.
Now, Eric Bettinger of Case Western Reserve University (EUCWRU) has reported mixed results. Math scores increased, but only white students were able to get paid. And there was no evidence of higher scores in reading, social studies and science. Official will decide later this year whether to continue the program.
小題1:Paying students who show improvement in tests __________.
A．has been done in most American schools
B．is becoming a growing practice in the USA
C．is not very popular with teachers
D．only aims at high scores at school
小題2:According to the text, Robert Schaefer _____________.
A．is a very excellent teacher
B．thinks highly of paying students
C．thinks students will show improvement in study in the future
D．thinks people should make a careful plan for the paying program
小題3:From the last paragraph we can see __________.
A．EBCWRU has got great success in its paying program
B．not all the students in EUCWRU have made progress in all subjects
C．only students who study math can get paid
D．EBCWRU will go on with the paying program
小題4:The text is mainly written to _____________.
A．persuade teachers to give students more prizes
B．tell people how to become an excellent student
C．introduce something about American paying students program
D．explain the advantages of American paying students program

If you’re like most students, you may find it challenging to learn a foreign language. However, there are a few tips you can use in order to earn a top grade —— as well as actually use the skills you’ve learned.
One of the most important and basic lessons in dealing with a foreign language is to learn and understand each concept and lesson before moving on to the next one. If you don’t understand one concept but move on to the next chapter anyway, you’re less likely to understand the new material.
Learning a new language is not only an academic tool, but can help you in your everyday life as well. Being good at another language can help you communicate with other people, and help you when traveling to foreign countries, and even make your resume look better.
And it is important to learn correct pronunciation as soon as possible for poor pronunciation can be hard to break. Native speakers of the language as well as others fluent in the language you are learning will appreciate your efforts to learn correct pronunciation.
Gather outside materials such as books, study guides, books on tape, and travel books to aid you in learning the language. Your textbooks can’t possibly teach you everything you need to know, so seeking outside sources is generally a good rule of thumb to keep in mind.
A significant motivator in learning a foreign language is traveling to the country where the language is spoken. That way, you can see firsthand how the language is used, learn the culture, and meet native speakers of the language. Native speakers appreciate sincere attempts of others who take the time to learn their language.
Seek out native speakers of your new language in your school or neighborhood. They can help you with many skills, including pronunciation, and they can provide immediate feedback on your progress.
小題1:This passage is written to        .
A．explain why learning a foreign language is challenging
B．tell us the importance of learning foreign languages
C．tell us some ways of earning a top grade
D．give us some tips on learning foreign languages
小題2:Which of the following can best summarize the main idea of Paragraph 3?
A．Think beyond academics.
B．Learn each concept.
C．Plan a trip to use your skills.
D．Consider a language as a tool.
小題3:We can learn from the passage that           .
A．textbooks are not good for us when learning a foreign language
B．learning pronunciation well from the very beginning is very important
C．poor pronunciation can be easy to break with the help of native speakers
D．seeking too many outside sources will be more harmful than beneficial
小題4:What is suggested doing in the last paragraph?
A．Going on a trip abroad.
B．Practicing with native speakers.
C．Asking for feedback from our teachers.
D．Finding a motivator in learning language.
小題5:In which part of a website would this text probably appear?

Making friends is a skill like most skills. It improves with practice. If you want to meet people and make friends, you must be willing to take some action. You must first go where there are people. You won’t make friends staying home alone.
Joining a club or a group, talking with those who like the same things as you do is much easier. Or join someone in some activity.
Many people are nervous when talking to new people. After all meeting strangers means facing the unknown. And it’s human nature to feel a bit uncomfortable about unknown. Most of our fears about dealing with new people comes from doubts about ourselves. We imagine other people are judging us, finding us too tall or too short, too this or too that. But don’t forget that they must be feeling the same way. Try to accept yourself as you are, and try to put the other person at ease. You’ll both feel more comfortable.
Try to act self-confident even if you don’t feel that way. When you enter a room full of strangers, such as a new classroom, walk tall and straight, look directly at other people and smile.
If you see someone you’d like to speak to, say something. Don’t wait for the other person to start a conversation.
Just meeting someone new does not mean that you will make friends with that person—friendship is based on mutual liking and “give and take”. It takes time and effort to develop.
小題1:The best topic of the passage may be ________.
A．FriendshipB．Making friendsC．Meeting New PeopleD．Facing the Unknown
小題2:Which of the following statements is NOT TRUE?
A．Making friends needs practicing.
B．Making friends needs to be more active in getting in touch with people.
C．When meeting someone, make him feel nice and easy.
D．Before making friends with someone, judge him if he’s too this or too that.
小題3:The development of friendship needs ________.
A．a(chǎn) lot of moneyB．lots of conversation

Research suggests that a newly-identified gene known as insomniacs(失眠癥患者) may play a role in keeping us asleep. By cloning and testing this gene in about 21,000 fruit flies, Rockefeller University researchers say they have discovered an entirely new mechanism (機制) by which sleep is controlled.
By studying these flies, the researchers discovered that mutations(變異) in the insomniac gene were associated with a great reduction in sleep. While a typical fruit fly slept for an average of 927 minutes a day, the mutant flies slept for just 317. They also slept for shorter periods of time, and slept and woke more frequently.
“The results showed a great loss of both the time that the flies’ sleep lasted and their ability to remain asleep after they slept,” says researcher Nicholas Stavropoulos.
The researchers also examined the link between sleep and lifespan, finding that flies with mutations to the insomniac gene lived only about two-thirds as long as unchanged flies. But when the scientists removed insomniac only in neurons（神經(jīng)細胞）---allowing it to remain in the rest of the flies’ bodies---this difference disappeared; the resulting animals slept poorly but lived just as long.
“This suggests that reduced sleep can be ‘uncoupled’(分開) from reduced lifespan, supporting the idea that some interruptions of sleep do not affect overall health, at least as far as lifespan is concerned,” Stavropoulos says.
Although flies and humans would appear to have little in common when it comes to lifestyle, scientists say that the mechanisms of sleep and wakefulness are likely to be quite similar.
“Sleep is a fundamental behavior in all animals, and it is poorly understood from a scientific standpoint, says Stavropoulos. This work could prove useful in understanding and treating sleep disorders”
小題1:The text is mainly about____.
A．the progress in cloning fruit flies
B．the methods of cloning fruit flies
C．the link between gene and lifespan
D．the influence of a gene on the ability to sleep
小題2:According to paragraph2, the mutant flies________.
A．slept about 5 hours a day
B．had problems waking up
C．didn’t seem sleepy at all
D．could not fall asleep
小題3:We can conclude from the text that________.
A．sleep and health go hand in hand
B．sleep can be controlled by humans
C．research into sleep is very fruitful

The scientific world continues to be amazed by the speed of the development of cloning. Some scientists now suggest that the cloning of humans could occur in the near future. Despite the benefits of cloning, however, certain ethical (道德的) questions concerning the possible abuse (濫用) of cloning have been raised. At the heart of these questions is the idea of humans influencing life in a way that could harm society, either morally or in a real physical sense. Some people object to cloning because it allows scientists to "act like God" in the handling of living organisms.
   The cloning of Dolly raised the debate over this practice to a whole new level. It has become obvious that the technology for cloning Dolly could also be used to clone humans. A person could choose to make two or ten or a hundred copies of himself or herself by the same techniques used with Dolly. An active debate about the morality of cloning humans arises. Some people see benefits from the practice, such as providing a way for parents to produce a new child to replace one dying of a fatal disease. Other people worry about humans taking into their own hands the future of the human race.
   At the beginning of the twenty-first century, many scientists say the controversy over the ethics of cloning humans is overstressed because of the unpredictability (不可預測性) of cloning in general. While scientists have cloned animals such as sheep, mice, cows, pigs, and goats, fewer than 3 percent of all those cloning efforts have succeeded. The animal clones that have been produced often have health problems. Scientists believe the rapid reprogramming in cloning can introduce random (任意的) errors into a clone’s DNA. Those errors have altered individual genes in minor ways, and the genetic defects (缺陷) have led to the development of major medical problems. Some scientists say this should make human cloning out of the question, but others argue that cloning humans may actually be easier and safer than cloning animals. Whatever, I agree that further research in the field of cloning is needed.
小題1:Some people are against cloning of humans because they think _________.
A．the practice takes too much time and money
B．the cloning technology is still not mature
C．humans control the future of the human race
D．the population in the world will be too large
小題2:Some scientists think the debate over ethics of cloning humans is overstressed because ____.
A．cloning of human beings is completely impossible
B．the result of cloning can’t be predicted in general
C．cloning of animals is a failure
D．there are big errors in a clone’s DNA
小題3:We can learn from the text that _______.
A．cloning of humans is a very controversial issue
B．the cloning of Dolly begins to raise the debate over cloning of humans
C．there are medical problems in cloning animals
D．cloning humans is easier and safer than cloning animals

An allowance(零花錢) is an important tool for teaching kids how to make plans for the use of money, save and make their own decisions. Children remem­ber and learn from mistakes when their own dollars are lost or spent foolishly.
How large an allowance is suitable? Experts say there is not right amount. Actual amounts differ from region to re­gion, and from family to family.
To set an suitable allowance for your child, work up a weekly plan. Allow for entertainment costs such as movies and snacks. Next, include everyday expenses such as lunch money, bus fare, school supplies. "If you make the child responsible for these bills’," says Josephine Swanson, a consumer specialist, " he or she will learn to plan for nec­essary costs."
Finally, add some extra money to make saving possible. If you can keep your child’s allowance in line with that of his friends. A child whose buying power falls away below his peers’ can feel left out.
It can be tough, but don’t excuse your children when they make a mistake with their allowance. When Brooke Ste­phens was ten and growing up in Jacksonville, her mother gave her $5 a week, $1.75 of which was for bus fare and lunch." If you lose your money," Brooke’s mother told her, "you walk home."
One week the girl spent all her allowance in a candy store, then she called home for a ride. " Mom made me walk home," recalls Stephens, now a financial planner in Brook­lyn. " At first I was angry. But I finally realized that she was trying to teach me an important lesson. "
Experts advise that an allowance should not be tied di­rectly to a child’s daily housework at home. Kids should help around the house not because they get paid for it but because they share responsibilities as members of a family. You might, however, pay a child for doing extra jobs at home, which can develop his or her early habits.
小題1:Which of the following is the possible title of the passage?
A．How to develop a child’s early habits.
B．How to work up an amount of pocket money.
C．How to teach a child about money.
D．How to teach a child to save money.
小題2: It can be inferred from the passage that if a child is given an allowance, he or she may ________.
A．spend all the money very soon
B．fall into the bad habit of wasting money
C．feel responsible and careful about money
D．lose the money and can not return home
小題3: In Paragraph 4, the words “his peers” refer to ________.
A．his parentsB．his friends
C．his financial expertsD．his teachers
小題4: Why does the writer mention Brooke Stephens?
A．To question the opinion about pocket money.
B．To compare Stephens with other financial experts.
C．To explain that parents should be strict when children are developing good habits about money.
D．To suggest pocket money is useless in developing a child’s sense of responsibility.
小題5: The writer implies in the passage that ________.
A．children may feel lonely if they have no pocket money
B．a(chǎn) child’s early good habits can be developed if he or she is paid for all the housework
C．paying children for their housework is no good
D．children may learn to put aside some money if they are given a great amount of pocket money

It’s true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There’s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: “The global warming over the last half-century has been caused mainly by human activity.”
You may not believe that humans could change the planet’s climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible (看不見的) blanket.
Of course, the earth’s climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth’s going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.
Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren’t carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”
The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.
小題1:In most scientists’ opinion, the global warming is mainly caused by ________.
A．solar activityB．volcanic activity
C．natural factorsD．human factors
小題2:The text is developed by ________.
A．giving typical examples
B．following the order of space
C．a(chǎn)nalyzing a theory and arguing it
D．comparing and finding differences
小題3:The underline word “identical” in the last paragraph probably means ________.
A．totally differentB．exactly the same
C．extremely importantD．partly independent
小題4:Which of the following is not the cause of climate change?
A．volcanic eruption
B．cycles concerning the Earth’s going around the sun
C．changes in solar
D．floods and droughts
小題5:Which of the following can be the best title?
A．Are All the Scientists Really Scientific?
B．Where Is Global Warming Leading Us to?
C．Are Humans Definitely Causing Global Warming?
D．What’s the Relation of Global Warming and Greenhouse Gases?
