The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth . Most of it will miss our planet , but two pieces will probably hit the southern half of the Earth .
On 17 July , a piece four kilometers wide enters the Earth’s atmosphere (大氣層) with a massive explosion . About half of the piece is destroyed , but the remaining part hits the South Atlantic at 200 times the speed of sound . The sea boils and a huge hole is made in the sea bed . Huge waves are created and spread outwards from the hole . The wall of water , a kilometer high , rushes towards southern Africa at 800 kilometers an hour . Cities on the African coast are totally destroyed and millions of people re drowned .
Before the waves reach South America , the second piece of the comet lands in Argentina . Earthquakes and volcanoes are set off in the Andes Mountains . The shock waves move north into California and all around the Pacific Ocean . The cities of Los Angeles , San Francisco and Tokyo are completely destroyed by earthquakes . Millions of people in the southern half of the earth are already dead, but the north won’t escape for long . Because of the explosions , the sun is hidden by clouds of dust , temperatures around the world fall to almost zero .Crops are ruined . The sun won’t be seen again for many years . Wars break out as countries fight for food . A year later , no more than 10 million people remain alive .
Could it really happen ? In fact , it has already happened more than once in the history of the Earth . The dinosaurs were on the Earth for over 160 million years . Then 65 million years ago they suddenly disappeared . Many scientists believe that the Earth was hit by a piece of object in space . The dinosaurs couldn’t live through the cold climate that followed and they died out . Will we meet the same end ?
小題1:What is mainly described in the passage ?
A．A historic discovery .B．An event of imagination
C．A research on space .D．A scientific adventure .
小題2:When the first piece hits the South Atlantic , it causes           .
A．a(chǎn)n earthquake B．damages to cities
C．a(chǎn)n Earth explosionD．huge waves
小題3:Why can’t the northern half of the earth escape for long ?
A．Because the land is covered with water
B．Because the light and heat from the sun can not reach the earth .
C．Because people there can not live at the temperature of zero .
D．Because wars break out among countries .

小題1:B
小題2:D

The UK's education system is ranked（排列） sixth best in the developed world, according to a global league table published by education firm Pearson in October,2012.
The first and second places are taken by Finland and South Korea.The rankings combine international test results and data such as graduation rates between 2006 and 2010.
Sir Michael Barber, Pearson's chief education adviser, says successful countries give teachers a high status and have a "culture" of education.
International comparisons in education have become increasingly significant - and this latest league table is based upon a series of global test results combined with measures of education systems, such as how many people go on to university.
The two education superpowers - Finland and South Korea - are followed by three other high-performing Asian education systems - Hong Kong, Japan and Singapore.
The UK is then only ranked at the head of an above-average group including the Netherlands, New Zealand, Canada and Ireland.
These are ahead of a middle-ranking group including the United States, Germany and France. At the lowest end are Mexico, Brazil and Indonesia.
These comparisons draw upon tests that are taken every three or four years, in areas such as maths, science and literacy - and so present a picture lagging by several years.
Looking at education systems that succeed, the study concludes that spending is important, but not as much as having a culture that is supportive of learning.
It says that spending is easier to measure, but the more complex impact of a society's attitude to education can make a big difference.
The success of Asian countries in these rankings reflects the high value attached to education and the expectations of parents. This can continue to be a factor when families migrate to other countries, says the report.
Looking at the two top countries - Finland and South Korea - the report says that there are many big differences, but the common factor is a shared social belief in the importance of education and its "underlying moral purpose".
小題1:What’s the main idea of the passage?
A．The two different education superpowers
B．The result of one report about education system .
C．The UK's education system is worst.
D．Finland and South Korea’S education system
小題2:According to Sir Michael Barber, Hong Kong’s education system is ranked       in the world.
A．2ndB．3rdC．4thD．5th
小題3:All of the following statements is NOT true EXCEPT ________.
A．At the lowest end are Mexico, Brazil and Indonesia.
B．Education firm Pearson is disappointed at The UK's education system.
C．The United States’ education system is one of the best.
D．There are many big differences in Finland and South Korea.
小題4:What does the underlined phrase “comparisons” in Paragraph 4 probably mean?
A．比較B．結(jié)果C．研究D．考試
小題5:What’s the common factor about the education system at the two top countries?
A. The shared social belief in the importance of education and its "underlying moral purpose".
B. The developed economy.
C The high value attached to education and the expectations of parents.
D. Having a culture that is supportive of learning.

Now let’s look ourselves as a species in relation to ecosystem balance.Modern scientists believe that humankind, like other animals, evolved(進(jìn)化) through millions of years of changes and adaptations to the environment and that our most direct evolutionary ancestor was probably an earlier species of the primate(monkey, ape) group. Despite this similarity with other creatures, however, the evolution of humankind differs from that of other species in one important and unique way.
In other species, evolution has led to specialization, both in the species abilities and in its place within the environmental structure. For example, the giraffe is much adapted to feeding on treetops, but it is also specialized and thus limited to feeding on trees and shrubs. Only with great difficulty can it bend down to graze on the ground. Similarly, the anteater is extremely well adapted to eating ants but is unable to catch or eat other animals. The same is true for countless other species.
For humankind it is opposite. Our evolution had led to a very generalized ability. Our highly developed intelligence and ability to make and handle tools mean that we can do almost anything. Humans evolved in such a way that we are able to move into every environment on Earth and even into space. No natural competitor offers great resistance, and other natural enemies such as disease have been controlled.
Said another way, we see in humankind a great imbalance between biological potential and environmental resistance. The result is the rapidly increasing world population, frequently referred to as the population explosion. Further, to support our growing population, natural ecosystems are being increasingly displaced by human habitations, agriculture, and other human supporting activities.
小題1:From the passage we can infer that in the course of evolution _______.
A．humankind is very important to earlier species, such as the primate group
B．human beings are limited by the environment while animals are not
C．human beings become more and more different from each other
D．humankind has experienced a generalization rather than specialization in ability
小題2:According to the passage, primate includes such animals as _______.
A．monkeys and anteatersB．tigers and apes
C．a(chǎn)pes and monkeysD．monkeys and giraffes
小題3:According to the passage, evolution has made it possible for humans to _______.
A．increase the population
B．resist natural offers
C．go to the moon
D．cure all diseases
小題4:According to the author, imbalance between biological potential and environ mental resistance has resulted in _______.
A．the population explosion
B．the destruction of human habitations
C．the growth of natural ecosystem
D．the specialization of humans

Here are six steps to better studying.
Pay attention in class
Do you have trouble paying attention in class? Are you sitting next to a loud person? Tell your teacher or parents about any problem that is preventing you from paying attention.
Take good notes
Write down facts that your teacher mentions or writes on the board. Try to use good handwriting so you can read your notes later. It’s a good idea to keep your notes organized by subject.
Plan ahead for tests and projects
Waiting until Thursday night to study for Friday’s test will make it hard to do your best. One of the best ways to make sure that doesn’t happen is to plan ahead. Write down your test dates. You can then plan how much to do after school each day, and how much time to spend on each topic.
Break it up
When there’s a lot to study, it can help to break things into several parts. Let’s say you have a spelling test on 20 words. Instead of thinking about all of the words at once, try breaking them down into five-word groups and work on one or two different groups each night.
Ask for help
You can’t study effectively if you don’t understand the material. Be sure to ask your teacher for help. If you’re at home when the confusion occurs, your morn or dad might be able to help.
Sleep tight
So the test is tomorrow and you’ve followed your study plan—but suddenly you can’t remember anything! Don’t panic. Your brain needs time to digest all the information you’ve given it. Try to get a good night’s sleep and you’ll be surprised by what comes back to you in the morning.
小題1:We know from the passage that a loud person is       .
A．a(chǎn) student who always answers questions loudly in class
B．someone who likes to talk with others in a loud voice
C．a(chǎn) student who likes speaking with others in class
D．a(chǎn) person who makes a lot of noise in public places
小題2:According to the author, which of the following is an effective studying method?
A．Don’t try to review everything you have learned in one go.
B．Try to review what you’ve learned in one go.
C．To read all your notes the night before the test.
D．Try to remember everything on the first try.
小題3:If you don’t understand what you have learnt, you can       .
A．read your notes over and over again
B．turn to people around you for help
C．put aside the material for later review
D．a(chǎn)sk your teacher to explain it the next day
小題4:By saying “Sleep tight”, what does the author mean?
A．Sleep again after waking up.
B．Sleep holding your breath deep.
C．Get a good night’s sleep.
D．Go to sleep early every night.

We live in a technological society where most goods are mass-produced by unskilled labor. Because of this, most people think that craft no longer exists.
One of the ways these people wrongly support their view is by pointing to 100-year-old homes which are still solid, and arguing that it is the craftsmanship that is responsible for their durability. “Homes in those days were well-built,” they say. No doubt these homes were well-built, but what these people have done is mix up the quality of material used in the house with the quality of the craftsmanship.
Homes today could be built to last just as long as those old homes if people were willing or able to pay the price. For example, most people can no longer afford solid oak stairways, although they were once fairly common in older homes. Nor can they afford the high labor cost of employing a carpenter to build the stairway. Yet if someone can pay the high cost, there are still plenty of carpenters around able to make those stairways. And not only would these carpenters know how to build them, they would probably do a better job than carpenters of old.
One thing the modern carpenter has which enables him to do a better job is much more advanced tools. Such tools as laser beams and powerplanes help them lay out a house better and make more precision cuts on the wood. Also, it is not uncommon say more to find carpenters with college degrees and carpenters with a solid knowledge of mathematics, which would enable them to deal with more difficult house designs.
The problem of modern quality, then, really boils down to the problem of material, for the modern carpenter is just as able to produce craftsmanship as the carpenter of fifty years ago, but only if given proper material.
小題1: Compared to the carpenters in the past, modern carpenters are           .
A．more successfulB．more learned
C．more imaginativeD．more hardworking
小題2: What does the underlined work “they” (paragraph 2) refer to?
A．Carpenters who are fond of oak stairways.
B．Carpenters who have college degrees.
C．People who think highly of carpenters of old.
D．People who think that modern material is of low quality.
小題3:What does the third paragraph mainly discuss?
A．People in the past preferred to use oak to build stairways.
B．It is now expensive to employ a carpenter.
C．Modern houses last as long as the old ones.
D．Good carpenters still exist in modern times.
小題4: What would be the best title for the text?
A．Is Craft Dead?B．Craft, Back to Life?
C．History of CraftsmanshipD．Carpenters Today and Yesterday

About twenty of us had been fortunate enough to receive invitations to a film-studio(影棚)to take part in a crowd-scene. Although our “act" would last only for a short time, we could see quite a number of interesting things.
We all stood at the far end of the studio as workmen prepared the scene, setting up trees at the edge of a winding path. Very soon, bright lights were turned on and the big movie-camera was wheeled into position. The director shouted something to the camera operator and then went to speak to the two famous actors nearby. Since it was hot in the studio, it came as a surprise to us to see one of the actors put on a heavy overcoat and start walking along the path. A big fan began blowing tiny white feathers down on him, and soon the trees were covered in “snow". Two more fans were turned on, and a "strong wind" blew through the trees. The picture looked so real that it made us feel cold.
The next scene was a complete contrast (對(duì)比). The way it was filmed was quite unusual. Pictures in front taken on an island in the Pacific were shown on a glass screen (幕). An actor and actress stood of the scene so that they looked as if they were at the water’s edge on an island. By a simple trick like this, palm trees(棕櫚樹), sandy beaches, and blue, clear skies had been brought into the studio!
Since it was our turn next, we were left wondering what scene would be prepared for us. For a full three minutes in our lives we would be experiencing the excitement of being film "stars"!
小題1:Who is the author?
A．A cameraman.
B．A film director.
C．A crowd-scene actor.
D．A workman for scene setting.
小題2:What made the author feel cold?
A．The heavy snowfall.
B．The man-made scene.
C．The low temperature.
D．The film being shown.
小題3: What would happen in the "three minutes" mentioned in the last paragraph?
A．A new scene would be filmed.
B．More stars would act in the film.
C．The author would leave the studio.
D．The next scene would be prepared.

When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behaviour. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory , Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.
小題1:What is the function of the first paragraph?
A．Leading the following paragraphs.
B．Showing the main idea of the passage.
C．Introducing the background of the passage.
D．Giving a summary of the passage.
小題2:Which of the following has the closest meaning to the underlined word “overrides” in the fourth paragraph?
A．is weaker thanB．is stronger thanC．is better thanD．is worse than
小題3: What can we learn from the passage?
A．Living ants can also be taken away when they are not moving.
B．When an ant dies, it can tell others using a certain chemical.
C．A living ant can pretend to be dead using a special chemical.
D．Ants often use chemicals to communicate with each other.
小題4:Which of the following descriptions about Dong-Hwan Choe is right?
A．Choe did this study in order to stop ants from invading new places.
B．Choe is a biologist who is only interested in animals, especially in ants.
C．Choe first came up with an idea to explain this ant behavior，and then did some tests to prove his theory.
D．Choe did the research on this ant behavior on his own

Usually, when your teacher asks a question, there is only one correct answer. But there is one question that has millions of current answers. That question is “What’s your name?” Everyone gives a different answer, but everyone is correct.
Have you ever wondered about people’s names? Where do they come from? What do they mean?
People’s first names, or given names, are chosen by their parents. Sometimes the name of a grandparent or other member of the family is used. Some parents choose the name of a well-known person. A boy could be named George Washington Smith; a girl could be named Helen Keller Jones.
Some people give their children names that mean good things. Clara means “bright”; Beatrice means “one who gives happiness”; Donald means “world ruler”; Leonard means “as brave as a lion”.
The earliest last names, or surnames, were taken from place names. A family with the name Brook or Brooks probably lived near brook(小溪)；someone who was called Longstreet probably lived on a long, paved road. The Greenwood family lived in or near a leafy forest.
Other early surnames came from people’s occupations. The most common occupational name is Smith, which means a person who makes things with iron or other metals. In the past, smiths were very important workers in every town and village. Some other occupational names are: Carter — a person who owned or drove a cart; Potter —a person who made pots and pans.
The ancestors of the Baker family probably baked bread for their neighbors in their native village. The Carpenter’s great-great-great-grandfather probably built houses and furniture.
Sometimes people were known for the color of their hair or skin, or their size, or their special abilities. When there were two men who were named John in the same village, the John with the gray hair probably became John Gray. Or the John was very tall could call himself John Tallman. John Fish was probably an excellent swimmer and John Lightfoot was probably a fast runner or a good dancer.
Some family names were made by adding something to the father’s name. English-speaking people added –s or –son. The Johnsons are descendants of John; the Roberts family’s ancestor was Robert. Irish and Scottish people added Mac or Mc or O. Perhaps all of the MacDonnells and the McDonnells and the O’Donnells are descendants of the same Donnell.
小題1:Which of the following aspects do the surnames in the passage NOT cover?
A．Places where people lived.
B．People’s characters.
C．Talents that people possessed.
D．People’s occupations.
小題2:According to the passage, the ancestors of the Potter family most probably _______.
A．owned or drove a cart
B．made things with metals
C．made kitchen tools or contains
D．built houses and furniture
小題3:Suppose and English couple whose ancestors lived near a leafy forest wanted their new-born son to become a world leader, the baby might be named _______.
A．Beatrice SmithB．Leonard Carter
C．George LongstreetD．Donald Greenwood
小題4:The underlined word “descendants” in the last paragraph means a person’s _____.
A．later generationsB．friends and relatives
C．colleagues and partnersD．later sponsors

Like distance runners on a measured course，all of us will move through time in a roughly predictable pattern．
In the first stage of our lives，we develop and grow, reaching toward the top of physical vitality(活力)．
After we grow up，however, the body begins a process of gradually wearing out．
A new awareness of physical fitness may help lengthen our years of health and vitality，yet nothing we do will work to stop the unavoidable force of aging．
Most of the changes of aging take place deep inside the body．The lungs become less able to take in oxygen．Powerful muscles gradually lose their strength．The heart loses power and pumps less blood．Bones grow easier to break．
Finally, we meet a stress，a stress that is greater than our physical resistance．Often，it is only a minor accident or chance infection(a disease caused by virus)，but this time，it brings life to an end．
In 1932，a classic experiment nearly doubled the lifetime of rats，simply by cutting back the calories in their diet The reason for the effect was then unknown．
Today, at the University of California at Berkley, Dr．Paul Seagle has also greatly lengthened the normal lifetime of rats．The result was achieved through a special protein limited diet，which had a great effect on the chemistry of the brain．Seagle showed that within the brain，specific chemicals control many of the signals that influence aging．By changing that chemical balance，the clock of aging can be reset．
For the first time, the mystery of why we age is being seriously challenged．Scientists in many fields are now making striking and far-reaching discoveries．
An average lifetime lasts 75 years，yet in each of us lies a potential for a longer life．If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years．
小題1:What does the underlined word “it” refer to?
A．Physical vitality．B．Stress．C．Aging．D．Physical resistance．
小題2:Which of the following is not a change of aging?
A．People gradually lose their muscle strength．
B．Bones tend to break more easily．
C．The heart loses power and pumps less blood．
D．The lungs become unable to take in oxygen．
小題3:The author believes the following except that     ．
A．human's life pattern is predictable
B．physical fitness can't stop the force of aging
C．human's lifetime will last longer than 75 years
D．a(chǎn)ll of the changes of aging take place deep inside the body
小題4:How did Dr．Paul Seagle lengthen the lifetime of rats in his experiment?
A．By keeping their physical fitness．B．By cutting the calories in their diet．
C．By resetting their clock of aging．D．By limiting the protein in their diet．
小題5:What is probably the best title for the article?
A．Two Great Experiments
B．The Mystery of Human Life
C．The Breakthrough in the Study of Aging
D．Ways to lengthen Human Life
