What is colour? Why do some of the things around us look red, some green, others blue?
　Colours are really made by reflected(反射)light. We see colour because most of the things reflect light. Something is red, for it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn‘t reflect any light, it is black.
　Some of the light is reflected and some is taken in(吸收)and turned into(變成)heat(熱能).The darker the colour is, the less light is reflected, the more light is taken in. So dark-coloured(深色的)clothes are warmer in the sun than light-coloured clothes.
小題1:When something reflects light, we can_______.
A．see its colourB．see its heatC．not see its colourD．see nothing
小題2:In summer _____make people feel cool.
A．dark-clolured clothesB．red-coloured clothes
C．green-coloured clothesD．light-coloured clothes
小題3:(Originally created) Why does the author use a question at the beginning of this passage?
A．The author doesn’t has a knowledge of colour.
B．The author shows off his knowledge of colour.
C．To ask the readers to answer this question.
D．To draw the readers’ interest in reading this passage.

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?
A．Entertainment.B．History.C．Education.D．Nature.

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

From a plane we can see the fields, cities, mountains or seas below. If we go into space, we see more and more of the earth. People and man-made satellites have been sent out into space to look at the earth carefully and people have learnt more about the earth in the last few years.
The sea looks very beautiful when the sun is shining on it. But it can be very terrible when there is a strong wind.
The sea is very big. It nearly covers three quarters of the earth. The sea is also very deep in some places. There is one place and at that place the sea is about 11 kilometers deep. The highest mountain in the world is about 9 kilometers high. If that mountain was put into the sea at that place, there would be still 2 kilometers of water above it!
In most parts of the sea, there are many kinds of fishes and plants. Some live near the top of the sea. Others live deep down. There are also a lot of small living things, and lots of fishes live by eating them.
The sea can be very cold. When people go down, the sea becomes colder and colder. Only some men can go down into the deep sea. But, in 1970, five women scientists (科學(xué)家) lived in the deep sea for fourteen days.

The goal of earthquake prediction is to give early enough warning. The U.S. Geological Survey conducts and supports research on the likelihood of future earthquakes. Scientists estimate earthquake probabilities in two ways: by studying the history of large earthquakes in a special area and the rate at which strain（拉力）accumulates（積累）in the rock.
Scientists study the past frequency of large earthquakes in order to determine the future likelihood of similar large shocks. For example scientists researched the large earthquakes in the San Francisco Bay region during the 75 years between 1836 and 1911. For the next 68 years, no earthquakes of magnitude (震級(jí)) 6 or large occurred in the region. Beginning with a magnitude 6 shock in 1979, the earthquakes in the region increased dramatically; between 1979 and 1989, there were four magnitude 6 or greater earthquakes, including a magnitude 7.1 earthquake. So scientists estimated that the probability of a magnitude 6.8 or larger earthquake occurring during the next 30 years in the region is about 67 percent.
Another way to predict earthquakes is to study how fast strain accumulates. When plate movements build the strain in rocks to a critical level, like pulling a rubber band too tight, the rocks will suddenly break and slip to a new position. Scientists measure how much strain accumulates along a fault (斷層) each year, how much time has passed since the last earthquake, and how much strain was released in the last earthquake. This information is used to calculate the time required for the accumulating strain to build to the level that results in an earthquake. This simple model is so complicated that such detailed information about faults is rare. In the United States, only the San Andreas Fault System has adequate records for using this prediction method.
Scientific understanding of earthquakes is of vital importance to the Nation. As the population increases, expanding urban development and construction encroach (侵蝕) upon areas susceptible(易受影響的) to earthquakes. With a greater understanding of the causes and effects of earthquakes, we may be able to reduce damage and loss of life from this destruction.
小題1:What does the passage mainly talk about?
A．What an earthquake is like.
B．How to predict earthquakes.
C．Where earthquakes often happen.
D．When a fault is formed.
小題2:That scientists study the history of large earthquakes in certain areas is to ultimately_________.
A．do research on the past frequency of large earthquakes
B．estimate the magnitude of similar earthquakes
C．forecast the possibilities of similar earthquakes
D．judge the specific location of future earthquakes
小題3:Which is TRUE according to the passage?
A．There were four magnitude 6 earthquakes in the San Francisco Bay region between1979 and1989.
B．The accumulating strain of the fault to a certain level results in the earthquake.
C．About 68 years after 1911, no earthquakes occurred in the San Francisco Bay region.
D．The fast increasing population on the earth is the main cause of the earthquake.
小題4:What is the critical factor of forming a fault?
A．The material of rocks.
B．The existing time span of the rocks.
C．The plate movements around the rocks.
D．The amount of strain released in the last earthquake.
小題5:According to the passage, we can know that the San Andreas Fault System____.
A．has a greater understanding of the causes and effects of earthquakes
B．stores much more information about the history of large earthquakes
C．offers the potential for doing research on the faults where strain accumulates
D．illustrates specifically how rocks along a fault are formed

Do you want to live another 100 years or more? Do you want to live never to die? Some experts say, it will be not a dream one day. Modern technology will make it come true. Man will live more years beyond what is now seen as the natural limit of the human life.
“ I think we are knocking at the door of immortality,” said Michael, a professor and author of two books on human life expectancy. “I think by 2075 we will see it and it’s no longer a dream. Human’s life expectancy may have not limit.”
At the meeting in San Francisco, Donald Louria, a professor at New Jersey Medical School said advances in using genes as well as other technology make it likely that humans will live in the future beyond what has been possible in the past. “There is a great push so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 300 or 500 years.”
However, many scientists are doubtful about it and say the human body is just not designed to last more than about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and other parts of the body will finally lead all humans to death.
Scientists also hold different opinions on what kind of life man might live.  “If you pass 120, you know; could you be healthy enough to have good quality of life? It’s a big question.” said Leonard Poon, director of the university center.  “At present people who could get to that point are not in good health at all.”
小題1:The underlined word in the second paragraph probably means _____.
A．dying slowlyB．living longerC．living foreverD．dying quickly
小題2:Donald’s attitude is that______.
A．human beings may never die in the future
B．it is not certain how long humans can live
C．the human body can last about 120 years
D．it is possible for man to live longer in the future
小題3:What would be the best title for this text?
A．Living longer or notB．Science and long living
C．No limit for human lifeD．Healthy lifestyle and living
小題4:In the last sentence “get to that point” means ____.
A．get that ideaB．get to 120 years old
C．know how to live foreverD．have good quality of life

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?

If music makes you smarter and exercise helps you to think, surely exercising to music can turn you into an intelligent person.
A team of scientists from Ohio State University did experiments on 33 volunteers who were getting better from heart disease following operation. They found that people who exercised while listening to Italian musician Antonio Vivaldi’s “The Four Seasons” did much better on language ability tests than without music.
“Facts suggest that exercise improves the learning ability of people with heart disease,” said the psychologist Charles Emery, who led the study. “And listening to music is thought to enhance understanding. We just wanted to put the two results together,” he added.
The volunteers said they felt better emotionally and physically after working out with or without the music. But their improvement on the test doubled after listening to music during exercise. Scientists have proved that music can be good for health, education and well-being. It helps reduce stress, sadness and nervousness; encourages relaxation or sleep; wakes up the body and improves memory and thoughts.
In medical fields, music is used widely for patients who have had head hurts before and after operation. “The Four Seasons” was used because of its moderate tempo（舒緩的節(jié)拍）and positive results in earlier research. “Exercise seems to cause positive changes in the nervous system(神經(jīng)系統(tǒng)) and these changes may have a direct result on learning ability,” Emery said.
Scientists have been studying the results of music on understanding since the early 1950s. By 2000, psychologists were using Mozart’s music, especially his violin pieces, to help children with speech disorders. Mozart was chosen because his music is not overexciting and has clear structures. A study showed students who listened to Mozart went on to score higher marks in an intelligence test. With important exams drawing near, your parents will not probably allow you to listen to music. But perhaps now you have good reasons to argue with them.
小題1:The underlined word enhance can be replaced by ______.
A．impressB．improveC．provideD．produce
小題2:The text mainly tells us that _____.
A．music and exercise lead to relaxation or sleep
B．33 volunteers work on music in medical fields
C．exercising to music makes people healthy and bright
D．scientists give suggestions on choosing music to exercise to
小題3:It can be learned from the last paragraph that ______.
A．you are supposed to follow your parents’ words
B．students should not listen to music before exams
C．you have some good reasons to exercise to music
D．music might help you to get higher grades in tests
小題4:Which of the following statements is true?
A．Exercise seems to cause negative changes without music.
B．Exercise reminds people with head hurts of what they’ve learned.
C．Scientists often use Mozart’s music, for it is not too exciting.
D．“The Four Seasons” is used to help children with speech disorders.
