What would it be like to take a walk on the surface of Mars? If you could design the tallest building in the world, what would it look like? Do you dream of being the next J．K. Rowling? This summer, you can experience all of these things, and more. All you need is an Internet connection and your imagination.
A recent study by the Kaiser Family Foundation found that kids spend an average of 1 hour and 29 minutes online each day. Many kids like to use that time to chat with friends, play games or check emails. But the next time you get on the Web, try exploring the world instead. “With the Internet, you can go back 11,000 years in time, or go 11,000 kilometers across the planet.” said Russell, Web search expert of Google. “The whole scope of history and the world is open to you.”
There is a wealth of information to be found online. For example, if your family is going on vacation somewhere，do a quick online search on the area before you even get in the car. “What's the background of the place; what's the history？” says Russell. “I like to tell my kids, ‘Whenever you have a question, whenever you have a doubt, search it out.’”
Ready to launch a virtual journey of your own? Here are a few starting points to get you thinking and to help you on your way. You can invite your parents along for the ride, too. Always ask for permission before downloading programs and software onto your computer. And check with a parent or an adult before visiting a new Web site.
Navigate the world in 3D with Google Earth. Begin in outer space and zoom(快速移動(dòng)) into the streets of any city, from Hong Kong to San Francisco. Or visit ancient monuments, watch the changing rainforests over time, and dive underwater to explore tropical reef.
With the Moon in Google Earth tool, you can walk in Neil Armstrong's famous footsteps. Take a guided tour of the moon's surface with Armstrong's fellow shuttle mate astronaut Buzz Aldrin.
When you're exploring that part of the solar system, hop on over to the Red Planet with Google Mars. There, you can move very quickly around the surface and see images from the Mars Rovers.

Plastic is one of the most important technological discoveries of the 20th century.However，it may soon be replaced.The new development—liquid wood—can replace plastics in all branches of modern industries.
Plastic as a material enjoys the biggest demand in the modern world，but it does have a number of drawbacks.First and foremost，plastic isn’t recyclable.Secondly，it contains toxins (毒物) helping develop cancerous diseases.Finally，it’s made of oil and oil reserves aren’t endless.
The liquid wood technology is likely to replace plastic and provide mankind with new materials for many years ahead.Norbert Eisenfreich，a senior researcher at the Faunhofer Institute for Chemical Technology (ICT) in Germany，said that arboform，the new material，is made of lignin (木質(zhì)素)，which can be obtained from soft tissues of wood.Once mixed with several other materials，it turns into solid and nontoxic alternative for plastics.
ICT team leader Emilia Regina InoneKauffmann said the woodworking industry separates wood into three basic components，including lignin.Lignin isn’t used for the production of paper.Specialists of ICT mixed lignin with several natural materials and thus invented the material which could be melted and molded (鑄型)．
When solid，arboform looks like plastic and possesses the qualities of polished wood.It can be used for the production of any items.Arboform is already used for the production of car parts which require extra strength.In addition，liquid wood can be recycled repeatedly.The material preserved all of its qualities even if it’s reprocessed ten times.
However，the new invention doesn’t enjoy an extensive use due to the high content of sulphur (硫) in it.German researchers are sure to reduce the amount of sulphur by 90 percent very soon to make arboform usable for home needs.
小題1:According to the passage，plastic________.

A．plays a big role in the modern world

B．helps to protect our environment in some way

C．has been replaced by the newly discovered material

D．helps us to reduce the use of petrol

小題2:What’s the advantage of arboform over plastics?

A．It is easily made from natural oil.

B．It is more widely used in household.

C．It is recyclable and friendly to the environment.

D．It contains no poisonous materials.

小題3:It can be concluded that German researchers will focus their future work firstly on________.

A．the material’s extensive use

B．the content of sulphur in arboform

C．the production cost of arboform

D．the qualities of liquid wood

小題4:The main purpose of the passage is to________.

A．a(chǎn)dvertise the new material—arboform

B．introduce liquid wood which will replace plastic

C．a(chǎn)dvertise new products made of arboform

D．show readers how to produce arboform

Researchers conducting a study of hospital stays for over two hundred and eighty six thousand older folks found something interesting in their data.
The number of hospitalizations for heart disease and stroke went down significantly among a certain group of people at a certain time of year. What folks, and what time of year, you ask? Flu season and the lucky people were the ones who got flu shots(流感疫苗).
It’s generally recommended that people over fifty get their flu shots every year. Influenza(流行性感冒) is no small thing. it’s responsible for around thirty six thousand deaths a year in the U. S. alone. Getting the shots also cuts down on the chances of getting pneumonia(肺炎), which is especially dangerous in seniors.
But what wasn’t known was that there seems to be an added benefit to getting a flu shots in terms of warding off heart problems. The data,in fact, are quite strong in suggesting this is the case.
In this study, flu shots cut clown the number of hospitalizations for heart disease by nineteen percent. Stroke went down sixteen percent one season and a whopping twenty-three percent a second season.These are big results.
So what's the connection between getting a flu shot and having a stronger heart? It isn’t yet known.
Researchers speculate that the flu virus itself may do damage to blood vessels(血管), possibly making clots(血塊)more likely. Blood clots in the heart can cause heart attacks, and blood clots in the brain can cause strokes.
Whatever the specific details are, there's one more good reason to follow your doctor’ s advice and get that annual flu shot.
小題1:According to the study, the number of hospitalizations for heart disease and stroke went down significanntly among the ones who _____.

A．got flu shots after they were ill

B．got flu shots before they were ill

Redwood trees are the tallest plants on the earth，reaching heights of up to 100 meters．They are also known for their longevity，typically 500 to 1000 years，but sometimes more than 2000 years．A hundred million years ago，in the age of dinosaurs，redwoods were common in the forests of a much more moist and tropical North America．As the climate became drier and colder，they declined to a narrow strip along the Pacific coast of Northern Califomia．
The trunk of redwood trees is very strong and usually forms a single straight column．It is covered with a soft bark．This bark can be pretty thick，well over two feet in the more mature trees．It gives the older trees a certain kind of protection from insects，but the main benefit is that it keeps the center of the tree harmless from moderate forest fires because of its thickness．This fire resistant quality explains why the giant redwood grows to live that long．While most other types of trees are destroyed by forest fires，the giant redwood actually prospers because of them．
Moderate fires will clear the ground of competing plant life，and the rising heat dries and opens the ripe fruit of the redwood，releasing many thousands of seeds onto the ground below．
New trees are often produced from shoots，little baby trees，which form at the base of the trunk．These shoots grow slowly，fed by the root system of the “mother’’ tree．When the main tree dies，the shoots are then free to grow as full trees，forming a “fairy ring” of trees around the original tree．These trees，in turn，may give rise to more shoots，and the cycle continues．
小題1:Why were redwood trees easier to find in the forests of North America millions of years ago?

A．The trees were taller and stronger．

B．The soil was softer for seeds to develop．

C．The climate there was warmer and wetter．

D．The temperature was lower along the Pacific coast．

小題2:Which of the following is a function of the tree bark as mentioned in the passage?

A．It allows redwood trees to bear seeds．

B．It prevents redwood trees from attack by insects．

C．It helps redwood trees absorb water in the air．

D．It makes redwood trees more beautiful and appealing．

小題3:Why do redwood trees grow to live that long according to the passage?

A．They have heavy and straight tree trunks．

B．They are properly watered and catered to．

C．They are more resistant to fire damage than other trees．

D．They produce many young trees to maintain their life cycle．

小題4:How does a “fairy ring’’ form according to the passage?

A．By killing an old tree．	B．By connecting root systems．
C．By inserting holes into old trees．	D．By surrounding a mature tree．

Although websites such as Facebook and MySpace experienced rapid growth during the middle of the first decade of the 21st century, some users remain unaware of the fact that the information they post online can come back to haunt them. First, employers can monitor employees who maintain a blog, photo diary, or website. Employers can look for controversial(引起爭(zhēng)議的) employee opinions, sensitive information disclosures, or wildly inappropriate conduct. For example, a North Carolina newspaper fired one of its features writers after she created a blog on which she wrote about the strange things of her job and coworkers without signing her real name.
The second unintended use of information from social networking websites is employers who check on prospective employees. A June 11, 2006 New York Times article reported that many companies use search engines and social networking websites such as MySpace, Xanga, and Facebook to conduct background checks on college campuses. Although the use of MySpace or Google to check a student’s background is somewhat unsettling to many undergraduates, the Times noted that the use of Facebook is especially shocking to students who believe that Facebook is limited to current students and recent alum(校友).
Corporate employers are not the only people interested in college students’ lives. The third unintended use of social networking websites is college administrators who monitor the Internet — especially Facebook — for student bad behavior. For example, a college in Boston’s Back Bay expelled (除名) its student Government Association President for joining a Facebook group highly critical of a campus police sergeant. In addition, fifteen students at a state university in North Carolina faced charges in court for underage drinking because of photos that appeared on Facebook.
Although more users of websites such as Facebook are becoming aware of the potential dangers of online identities, many regular users still fail to take there basic security precautions(警惕). First, only make your information available to a specific list of individuals whom you approve. Second , regularly search for potentially harmful information about yourself that may have been posted by mistake or by a disgruntled
(不滿的)former associate. Thrid, never post obviously offensive material will likely make its way to the wider world. By taking these simple steps, members of the digital world can realize the many benefits of e-community without experiencing some of the damaging unintended consequences.
小題1:The main purpose of the passage is to _____.

A．explain the growth of the digital world from the view of privacy

B．discuss the risks of the digital world and suggest ways to protect yourself

C．propose steps Facebook, MySpace and Google can take to protect user privacy

D．illustrate(說(shuō)明) potential unintended uses of private information

小題2:The writer implies that users should take all of the following actions to protect their online privacy EXCEPT _____.

A．know to whom you make your online information available

B．a(chǎn)ctively hunt for damaging information posted about you or under your name

C．speak with employers to inform them of any misinformation published about you

D．a(chǎn)void uploading information that would be extremely damaging if it were discovered

小題3:According to the passage, which of the following does the author imply?

A．Information obtained unwillingly from the Internet is permitted in court.

B．It is impossible to protect yourself from unintended uses of information online.

C．Even if you restrict who can view your data, the government may still access it.

D．Done properly, posting offensive information about oneself brings no risk.

小題4:In the last paragraph the author mainly _____.

A．offers detailed examples to support previous viewpoints

B．further explores the ill-effects of the Internet on the protection of privacy

C．summarizes the points of the above paragraphs

D．provides suggestions to overcome the previously mentioned problems

What's going to happen in the future? Will robots take over our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen 10 to 30 years later from now, according to the BBC.
1．Digital money
We used to pay with cash for everything we bought. Now when we swipe(刷) our bus pass or use a credit card to shop online, money is spent without us even seeing it. In fact, we are already using one type of digital money.
You have to admit that using a card is much easier than searching your pockets for change. It is also safer than carrying a lot of cash.
When ATM cards were first introduced, they were not accepted everywhere. But now it's hard to live without them. People in Sweden completely stopped using cash last year, according to the Associated Press, and the US might be next.
2．Bionic(能力超人的)eye
It's no longer something only in a scifi movie. People who are blind may have a chance to get their sight back—by wearing bionic eyes.
A blind eye can no longer sense light, but a bionic eye can use a camera to “see” the environment and send data directly to the brain.
Although the bionic eye that's out now only allows patients to see lights and unclear shapes, a highresolution(高清晰度的) version could be just a few years away.
3．Selfdriving cars
Everything is going automatic these days—washing machines, ticket selling machines and even cars. Unlike a human driver, a selfdriving car won't get distracted by a phone call, the radio or something outside the window. Sensors and cameras on the car would allow it to stick strictly to the rules of the road and keep a safe distance from other cars. This would greatly reduce the number of road accidents. You could even take a nap while the car drives itself.
Many vehicle companies are now planning selfdriving cars. “By 2040, driverless vehicles will be widely accepted and possibly be the dominant vehicles on the road，” said Jeffrey Miller, professor at the University of Alaska Anchorage, US, in Wired magazine.
小題1:The underlined word “distracted” in the article is closest in meaning to “________”．

A．directed	B．discouraged
C．a(chǎn)ttacked	D．disturbed

小題2:Jeffrey Miller's attitude towards selfdriving cars is ________.

A．optimistic	B．pessimistic
C．doubtful	D．cautious

小題3:Which section is the article most likely to be found in the newspaper?

A．Learning Kit	B．Campus Trends
C．Entertainment	D．Technology

Recently we told you about a finding that more years of school could help students get higherscores on intelligence tests．That was the finding of a study of teenage males in Norway．Now，other research shows that physical activity may help students do better in their classes .
The research comes as educators in some countries are reducing time for activities like physical education．They are using the time instead for academic subjects like maths and reading．The studies appeared between 2007 and 2013．They included more than 55，000 children，aged 6 to 18．
Amika Singh：“Based on the results of our study，we can conclude that being physically active is beneficial for academic performance. There are，first，Physiological explanations，like more blood flow, and so more oxygen to the brain．Being physically active means there are more hormones(荷爾蒙)produced like endorphins(內(nèi)啡肽)．And endorphins make your stress level lower and your mood improved, which means you also perform better.”
Also，students involved in organized sports learn rules and how to follow them．This could improve their classroom behavior and help them keep their mind on their work．
The study leaves some questions unanswered，however．Ms．Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement．This is because of differences among the studies .
Also．they were mostly observational studies．An observational study is where researchers do not do controlled comparisons．They only describe what they observe．So they might observe a link that students who are more active often have better grades．But that does not necessarily mean being active was the cause of those higher grades．
The researchers said they found only two high - quality studies．They called for more high-
quality studies to confirm their findings．They also pointed out that “outcomes for other parts of the world may be quite different. ”
Still，the general finding was that physically active kids are more likely to do better in school．Ms．Singh says schools should consider that finding before they cut physical education programs．Her paper on “Physical Activity and Performance at School”is published in the Archives of Pediatric and Adolescent Medicine．
小題1:The passage mainly tells us that ＿＿＿＿

A．a(chǎn) research on physical education has been done by the researchers

B．there exists a possibility that physical activity leads to higher grades

C．the amount or kind of activity directly affects academic level

D．the research shows that the children aged 6 to 1 8 don't do sports

小題2:Which of the following is TRUE?

A．Being mentally active is good for academic subjects．

B．The more hormones you have，the more stressed you will get．

C．They have found many high-quality studies to prove the research．

D．The educators in the research think studies，not exercise，mean much to students．

小題3:The underlined sentence in Paragraph 7 probably means ＿＿＿＿.

A．good marks result from high-quality study

B．findings probably vary in different areas

C．physical activity will spread all over the world

D．a(chǎn)cademic performance depends on the surroundings

小題4:What's the purpose of writing the passage?

A．To call our attention to the sports at school．

B．To introduce all types of physical activities．

C．To represent the academic performance．

D．To improve students' health ．

Many people don't realize the importance of music education in the schools today．A new study showed, however, music education is extremely important．
In college, music education is one of the largest programs．Teachers have to learn general education materials and techniques． They must learn to play every instrument; they must learn music history and music theory; they must learn instrument repair and teaching methods; they must learn conducting and so much more．At the same time, much of our culture and tradition is absorbed in music．
Music plays a very important role in our education．
Music helps with math and science． Students learn to count, and how to multiply and divide．Students also use science to help them discover what sounds good together and what doesn't．Students also need science to understand something called the “overtone series", which is about how music is produced by vibration（顫動(dòng)）and why．
Students learn a lot about languages through music．Many songs are written in other languages, including ancient ones．Students must learn to translate these works to understand what they are singing about． A song is likely to be a famous short work set to music; so students are exposed to that very often while singing．
Students learn a huge amount of cooperation （協(xié)作）of body parts through music, so parts of the body can work better together．Students must use motor（肌肉運(yùn)動(dòng)的）skills in order to play an instrument．Singers and wind（管樂(lè)器）players must learn breath control and be in good shape to play．
Students learn about art． Some famous pieces were written about important pieces of art, and students learn about the artists and styles as they're playing the music．
Music education also brings higher thinking to our children．It allows them to think about complex patterns．Students have to be aware of what every other musician does at every time．In that way, it develops cooperation, as well．They tend to develop more ability for learning．
As one can see, music is very important to education．
小題1:According to the passage, learning music in college will be quite ．

A．easy

B．stressful

C．a(chǎn)ttractive

D．useless

小題2:As to the benefits from music, which of the following is NOT included in the passage?

A．Calculation．	B．Language study．
C．Relaxation．	D．Cooperation of body parts．

小題3:The underlined word "that" in Para．5 refers to“ "．

A．the music	B．the language
C．the culture	D．the work

小題4:What can we know from the passage?

A．Science and music are extreme poles．

B．Only the wisest person can learn music well．

C．Music is good to our all-round development．

D．All of us know the importance of music clearly．

A good teacher is many things to many people. In my own experience, the people I respect the most and think about the most are the teachers who demanded (要求) the most discipline (紀(jì)律) from their students.
I miss one teacher in particular that I had in high school. I think she was a good teacher because she was a very strict person. I remember very vividly (清晰地) a sign over her classroom door. It was a simple sign that said, “Laboratory—in this room the first five letters of the word was emphasized (強(qiáng)調(diào)), not the last seven.” In other words, I guess, labor for her was more important than oratory, which means making speeches.
She prepared her work very carefully and demanded us to do the same. We got lots of homework from her. Once she had broken her arm, and everybody in the class thought that maybe the homework load would be reduced, but it continued just the same. She checked our work by stamping her name at the bottom of the papers to show that she had read them.
I think sometimes teachers who demand the most are liked the least. But as time goes by, this discipline really seems to benefit (有益于) the students.
小題1:Which of the following is considered a good teacher by the writer?

A．A patient teacher.	B．An honest teacher.
C．A strict teacher.	D．A hard-working teacher.

小題2:The teacher put up the sign over her classroom door ___.

A．to remind the students that this room was a laboratory

B．to advise the students to follow the disciplines

C．to warn the students not to be careless

D．to tell the students to work hard in the classroom

小題3:When the teacher’s arm was broken, she ___.

A．gave her students the usual amount of homework

B．gave her students less homework

C．a(chǎn)sked her students to check the homework themselves

D．gave her students more homework

小題4:What’s the writer’s opinion of discipline?

A．It makes the students dislike their teachers.

B．It does good to the students in the long run.

C．It’s too much for young children.

D．It does more harm than good to the students.
