Why would an animal kill itself? It seems a strange question, and yet it is one that has made some scientists curious for a long time. For there is a kind of animal called lemming（旅鼠）, that periodically killed themselves together, and no one knows just why!
The small creatures which live in the Scandinavian mountains, feed on a diet of roots and special insects and live in nests they dig underground. When their food supply is large, the lemmings live a normal and undisturbed life. 
However, when the lemmings’ food supply becomes too low to support the population, a singular migration（遷徙）begins. The lemmings leave their nests in groups. Great numbers of them begin to travel across the Scandinavian plains, a journey that may last weeks. The lemmings eat everything in their path, continuing their long march until they reach the sea. 
The reason for what follows remains unbelievable to naturalists. Upon reaching the coast, the lemmings do not stop but swim by the thousands into the sea. Most stay afloat only a short time before they tire, sink and drown. 
A common theory for this mass self-killing is that the lemmings do not realize that the ocean is such a huge body of water in their cross-country journey, the animals must cross many smaller bodies of water, such as rivers and small lakes. They may think that the sea is just another such swimmable path to go through. But no final answer has been found to the strange happening. 
小題1:The passage is mainly about______. 
A．how lemmings find food
B．why animals kill themselves
C．the lemmings’ self-killing
D．the food supply in the Scandinavian mountains
小題2:A reason for the lemmings’ self-killing might be that they______. 
A．go mad from a lack of food
B．hope to find fish for food
C．decide to reduce the population
D．think they can cross the sea
小題3:Why are scientists curious about the lemmings’ behavior?
A．Because they are the only animals that live in Scandinavia.
B．Because it is very unusual for animals to kill themselves.
C．Because of the amount of food they can eat on their march to the sea.
D．Because they can gather together in such huge numbers.
小題4:The underlined word “singular” means______.
A．unusualB．singleC．wonderful D．common

Children, especially at young ages, are very creative. And creativity can be a glorious(極好的) thing. Look at all the amazing artists and architects that have created glorious pieces of history. Look at all the authors with the award winning books. Now I am not saying everyone is going to end up this way but creativity is an important part of growing up and becoming who you are. This should be encouraged in young children as well as the older children.
Young children grow up playing with make-believe. And so many people try to make their young child see that their invisible friend isn’t real or that talking when someone is not in the room is weird. To adults it is, but for small children it is them being creative. May it be them playing house, or chef, or playing with stuffed animals, it is their creative part coming out. Some kids can have fun playing with rocks and sticks and it’s because of their creativeness that they can do this. The invisible friend part is another part of being imaginative, and is not a bad thing since they will grow out of that phase(階段). So encourage this and play along with them, play house, or stuffed animals or whatever they want to play. Help keep their imagination running. You can even make up games, like treasure hunts, or dinosaurs, super heroes; there is just so much you can choose from.
All this can help your children’s minds stay creative. The arts and music, even thoughts are an important part of life and important in our society. If we didn’t have and encourage creative thinking, we wouldn’t have had inventors, or philosophers, or as I said before, artists.
小題1:The underlined word “weird” is close in meaning to            .
A．familiarB．strangeC．commonD．natural
小題2:According to the author, if a child talks alone in a room, we should          .
A．let him be
B．stop him from doing so
C．give him some advice
D．know that he is suffering from loneliness
小題3:What is mainly talked about in the passage?
A．How creative artists and architects are born.
B．How to help children grow up in a healthy way.
C．What kind of activities children like.
D．How to help children to be creative.
小題4:The author of the passage would agree that          .
A．every child can become creative artists or inventors
B．creative people all show strange behaviors when young
C．creativity brings out great artists and architects
D．creativity is a natural ability to be born with

Frogs are animals that can live both in water and on land. There are more than 5,000 kinds of frogs on the earth. The earliest known frogs lived about 190 million years ago and the frogs today still look the same. Here are some fun things that you might not know about frogs. Enjoy!
The Biggest and the Smallest Frogs
Some frogs can be very big. The biggest kind of frog is the Goliath Frog in West Africa. Its body can be nearly 30cm long, about the size of a large cat. The Gold Frog and the Poison Frog are the smallest frogs in the world. They are less than 1cm long. Though the Poison Frog is very small, it is not weak at all. It is dangerous. Any animal that eats it will die very soon.
The Best Jumpers
Frogs are very good at jumping. They developed jumping legs so that they would not be eaten by other large animals. Using their big strong legs, more frogs can jump over 20 times their own length. It is like a person jumping over about 30,48. The Australian Rocket Frog can even jump over 2m, which is 50 times its body length(5.5cm). That might be the reason why frogs are called the best jumpers on the earth.
The Cryogenic Animal
Some frogs like the Common Wood Frog have a special ability to live in very cold places. When the temperature goes down, they become ice frogs. 2/3of their body water freezes. Their hearts stop, and their breathing stops too. You may think they are dead, but in fact they are not. Maybe we humans can learn the way that the frogs do for medical purpose.
小題1:The earliest frogs lived about ________ million years ago.
A．20B．30C．50D．190
小題2:The Gold Frog is one of the ________ frogs on the earth.
A．smallestB．biggestC．strongest D．weakest
小題3:________ can jump over 2m.
A．The Goliath FrogB．The Common Wood Frog
C．The Poison FrogD．The Australian Rocket Frog
小題4:What will happen to a Common Wood Frog at very low temperature?
A.It will die very soon.   B. It will be an ice frog.
B.It will become dangerous.   D. It will become very small

Poor Oral Health Leads to Social and Emotional Problems
A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems.
Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection.
The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes  in permanent teeth are also known as caries.
"Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too."
He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations.
"It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation."
Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods.
But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less.
Wagner Marcenes is calling for an "urgent, organized, social response" to the widespread lack of oral health. He believes in a natural method to fight tooth decay by having a healthier diet. He is also calling for the development of new and less costly dental materials and treatments.
小題1:From the passage, we know that Wagner Marcenes ______.
A．works as the leader of the Institute of Dentistry at Queen Mary, University of London.
B．a(chǎn)nd his researchers accumulate some studies to find out some ways to cure all major disease.
C．is in charge of the activity to estimate the infection rate with the collected and examined studies about all major studies.
D．thinks that the most serious problem caused by tooth decay is cancer that will last for a long time.
小題2:Caries is a disease that ______.
A．is listed in the most common of all 291 major diseases and injuries which will last for a long time..
B．is closely related to industrialized diet which calls for people to eat slowly.
C．increases in Africa now because developing countries are becoming developed countries.
D．will cause phychological disorder which will affect people’s communication.
小題3:The writer wrote this passage in order to ______.
A．a(chǎn)rouse people’s concern about caries and take measures to deal with it.
B．tell the result of the Global Burden of Disease 2010 study.
C．warn people in Africa to adjust their diet to prevent caries.
D．tell doctors that caries affects a person’s quality of life.
小題4:What is the writer’s attitude towards tooth decay?
A．indifferentB．concernedC．a(chǎn)ngryD．negative

An Ofsted (英國(guó)教育標(biāo)準(zhǔn)辦公室）study reports that teachers are discouraging students who want to leave school and work as apprentices (學(xué)徒）in beauty salons (美容中心）or hair dressers.
　　Inspectors questioned 105 young people for a report on apprenticeships published on Wednesday. They found several examples of young people who felt they had been laughed at by their teachers for wanting to progress to work-based learning, particularly in care or hairdressing, rather than stay on at school.
　　Right or wrong, is it any surprise that this is happening? From 2014，the government will measure schools according to the rate of their pupils who go to university. Brian Lightman , general secretary of the Association of School and College Leaders, says the government has already put teachers under “very great pressure to focus on academic subjects”
　　On the other hand, the Education Act 2011，which came into force in November, places schools under a duty to give fair career advice to pupils. This advice must include information on all post-16 education and training choices, including apprenticeships. This doesn’t appear to be happening in several schools, according to Ofsted9S report. Many of the young people the inspectors talked to said the advice they had received on apprenticeships was “unsatisfactory”.
　　Schools were also blamed for lack of work experience courses, which are particularly important for teenagers considering an apprenticeship. They help students decide whether they enjoy a line of work and enable employers to see whether those on work experience have the potential to be hired as apprentices in future years.
　　But there is a good reason why they can’t do this: they’d be unable to adapt to GCSE (英國(guó)齊通中等教育證書(shū)）exams if they did. Sometimes, it seems, schools just can’t win.
小題1:Why do teachers oppose the students’ leaving school and working as apprentices?
A．The government urges teachers to concentrate on academic subjects.
B．The students are only wasting time working as apprentices.
C．Employers are under great pressure of taking GCSE exams.
D．Employers don’t give students chances to work as apprentices
小題2:Pressure for schools to provide pupils with career advice comes from ______. 
A．Association of School and College Leaders
B．Education Act 2011
C．GCSE exams
D．OFSTED
小題3:The underlined word “They” in Paragraph 5 refers to _____.
A．schools
B．employers
C．work experience courses
D．teenagers considering an apprenticeship
小題4:What does the author think of teachers’ discouraging students working as apprentices?
A．SurprisingB．Understandable
C．WrongD．Right

In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet (彗星). When the fragments (碎片) landed in the southern part of the giant planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet?
　The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the Earth. The news has caused panic.
　On 17 July, a fragment four kilometers wide enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.
　Millions of people are already dead in the southern part of the Earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.
　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 space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end?
小題1:55.Which of the following is NOT TRUE according to the author's description of the disaster in 2094?
A．The whole world becomes extremely cold
B．All the coastal cities in Africa are destroyed
C．The visit of the comet results in wars
D．The whole mankind becomes extinct
小題2:56.Why does the author mention dinosaurs at the end of the passage?
A．Because they could only live in the warm climate
B．Because their extinction indicates future disasters
C．Because they once dominated the earth
D．Because dinosaurs and humans never live in the same age
小題3:57.In writing the passage, the author intends to ______.
A．give an accurate description of the possible disaster in the future
B．prove that humans will sooner or later be destroyed
C．warn of a possible disaster in the future
D．tell the historical development of the Earth
小題4:58.It can be concluded that the passage is most probably part of a(n) ______.
A．a(chǎn)rticle of popular scienceB．news report
C．research paperD．horror story

John Davis doesn’t use his GPS system in his car. Instead of guiding the direction, the Delaware farmer uses it to determine where and how much fertilizer to use on the crops on his 4,000-acre family-owned farm. Technological advances like that last year helped Davis and other Ohio farmers set a record for corn product. Ohio's corn crop in 2009 totaled 546 million bushels(蒲式耳), despite a cooler and wetter than normal spring, a dry summer and a delayed, wet harvest. Davis said. “I knew it would be a good crop, but it was much better than we expected.”
A farmer can map his fields on GPS, spotting where soil turned out to be least fertile（肥沃的） and using more fertilizer the next year in those areas where corn didn’t grow as well.
Although Ohio farmers produced more corn, it was grown on less land than in the past years. Total area used for corn in Ohio was 3.35 million acres, about the same as in 2008 but down from 3.85 million acres in 2007, said Dwayne Siekman, director of the Ohio Corn Growers Association. “When you look at the total number of acres in Ohio used for corn, it’s clear that farmers are able to do more with less,” he said. “American farmers can grow five times more corn on 20 percent less land than they did in the 1930s, saying that modern farming techniques are necessary for a growing demand in the world today.” That technology includes using improved seeds that can withstand(忍受) greater temperature extremes and pests, Siekman said.
Farmers aren't the only ones who benefit. Consumers(消費(fèi)者) do, too, as food costs reduce in the face of “enough supplies of corn,” said Fred Yoder, who runs a 1,500-acre corn, soybean and wheat farm in Plain City. “This is the best, highest-producing corn crop that I've raised in 30 years,” he said.
小題1:Most people usually use the GPS system for ______.
A．driving their cars
B．telling the position
C．mending the car
D．supplying the sunshine
小題2:The farmers in Ohio use GPS to ______.
A．check if the soil is fertile in some areas
B．control the rain of the place
C．water the crops if the weather is dry
D．draw the map of all the crops
小題3:Why did Ohio farmers produce more corn?
A．Because they expanded more land to grow corn
B．Because they turned to technological advances
C．Because they used more and more fertilizer.
D．Because they supplies themselves with more money.
小題4: From the passage, we can know _____.[
A．John Davis hadn’t expected a good harvest.
B．farmers grew less land than in the 1930s
C．improved seeds cost much more money
D．the output of corn in the same field is increased.

Medicine comes in lots of different packages. Painkillers in a tablet can make your headache go away. Antibiotic cream (抗菌素膏) from a tube can prevent your cuts from becoming infected. But can medicine come packaged in chicken eggs?
A team of scientists from Scotland say “yes”. They’ve engineered special chickens that lay eggs with disease-treating drugs inside. 
These eggs come from chickens that have been engineered to produce certain drugs inside their egg whites.
These drugs are made of molecules called proteins(蛋白質(zhì)). Animals make thousands of proteins — they’re the main element in skin, hair, milk and meat. Since animals can make proteins easily, they’re good candidates (候選者) for making protein drugs.
Researchers have already made cows, sheep and goats produce protein drugs in their milk. But chickens are cheaper to take care of, need less room, and grow faster than these other animals. Those qualities could make chickens a better choice to become living drug factories, says Simon Lillico of the Roslin Institute near Edinburgh, Scotland.
Lillico and a team of researchers changed chickens’ DNA — the code that tells cells how to make proteins — so that the birds’ cells made two protein drugs. One drug can treat skin cancer, and the other treats a nerve disease called multiple sclerosis (多發(fā)性硬化).
The scientists changed the chickens’ DNA so that the birds made these drugs only in their egg whites. This protects the chickens’ bodies from the drugs’ possible harmful effects and makes it easy for scientists to collect the drugs.
小題1:If you cut your finger, you may use ________ to cure it.
A．painkillers in a tabletB．a(chǎn)ntibiotic cream from a tube
C．chicken eggs D．protein drugs
小題2:Which of the following statements is NOT true?
A．Scientists from Scotland have succeeded in packing medicine into chicken eggs.
B．The drugs are made of molecules called proteins.
C．Scientists chose chickens for their experiments because chicken eggs taste delicious.
D．The animals are good candidates for making protein drugs.
小題3:The drugs in special chicken eggs can ________.
A．treat lung cancer B．help reduce headache
C．change people’s DNA D．treat multiple sclerosis
小題4:We can infer from the passage that ________.
A．eating eggs is the best choice for the patients now
B．scientists changed the chicken’s DNA and put all the drugs in chicken eggs
C．we may eat special eggs as drugs when we are sick in the future
D．the drugs produce harmful effects on the chicken’s bodies

Life on earth depends on water, and there is no substitute for it. The current assumption is that our basic needs for water—whether for drinking, agriculture, industry or the raising of fish—will always have to be met. Given this premise (前提), there are two basic routes we can go; more equal access to water or better engineering solutions.
Look at the engineering solutions first. A lot of my research concentrates on what happens to wetlands when you build dams in river basins, particularly in Africa. The ecology of such areas is almost entirely driven by the seasonal changes of the river—the pulse of the water. And the fact is that if you build a dam, you generally spoil the downstream ecology. In the past, such problems have been hidden by a lack of information. But in the near future, governments will have no excuses for their ignorance.
The engineers’ ability to control water flows has created new kinds of unpredictability, too. Dams in Africa have meant fewer fish, less grazing and less floodplain (洪泛區(qū)) agriculture, none of which were expected. And there average economic life is assumed to be thirty years. Dams don’t exist forever, but what will replace them is not clear.
The challenge for the future is to find new means of controlling water. Although GM technology(轉(zhuǎn)基因) will allow us to breed better dry-land crops, there is no market for companies to develop crops suitable for the micro-climates of the Sahel and elsewhere in Africa. Who is going to pay for research on locally appropriate crops in the Third World?
小題1:What’s the main idea of this passage?
A．The engineering solutions to water resource and their limitation.
B．The challenge for the future.
C．The basic means of controlling water.
D．The challenge for developing crops.
小題2:The author suggests that governments will have no excuse for their careless ignorance in the future because _____.
A．The ecological destruction will be known to the public by researchers
B．The ecological destruction will no longer be a problem in the future
C．The future is an information age
D．Governments will face greater challenge in the future
小題3:Which of the following statements is NOT true for meeting our basic needs for water?
A．Water resource should be used more reasonably.
B．More dams should be built in river basins.
C．More wetlands should be protected from destruction.
D．More dry-land crops could be developed in Africa.
小題4:The last sentence probably implies that _____.
A．No one will invest in developing locally appropriate crops in Africa
B．Researchers have no interest in developing dry-land crops
C．Research on locally appropriate crops in the Third World may be profitable
D．There is less water resource in the Third World
