There has been a dramatic increase in the number of natural disasters over the past few years, and it is assumed that global warming and climate change could cause even more disasters in the future. Some of the world’s leading cities are facing disasters like floods and heat waves.
London
London’s flood defences are getting older. Since 1982, the Thames Barrier(水閘)has protected the city from the threat of flooding, but it was only designed to last until 2030 and close once every two or three years. About 26 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not addressed.
There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property in London’s flood risk area, so large scale flooding would be disastrous.
Paris
Over a six week period in July and August 2003, more than 1 1,400—mainly elderly people—died in France from dehydration(脫水)and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity(強度)are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?
One solution is to have air-conditioners installed in elderly care homes. But this is considered a short-term solution, as the increase in demand for electricity also increases carbon emissions(排放).
In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower,” which uses a covering of bamboo to act as a natural air-conditioner.
Shanghai
Shanghai is the fastest growing city on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.
An estimated 250，000 people move to Shanghai every year in search of work, placing extra demands on energy consumption. China relies heavily on coal—fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.
小題1:What problem should be settled now in London?
A．How to protect the city’s property
B．Where to build its flood defences
C．How to use the Thames Barrier to protect the city
D．How to improve the function of the old flood defences
小題2:Which of the following measures can’t solve the heat wave disaster in Paris?
A．Putting up new types of buildings with a covering of bamboo
B．Having air-conditioners installed in elderly care homes
C．Forbidding the city to build“Flower Tower”
D．Encouraging architects to design new types of buildings
小題3:The major threats to Shanghai are          ．
A．increasing population and coal-fired power stations
B．rising sea levels and typhoons
C．extremely high temperature and rising sea levels
D．extra demands on energy consumption and typhoons
小題4:The purpose of the passage is      ．
A．to tell us how to protect the big cities
B．to give advice on how to defend natural disasters
C．to explain what causes flood and heat waves
D．to warn us of the increasing natural disasters in big cities
小題5:Which of the following would be the best title for the passage?
A．Big Cities Facing Big Disasters
B．Big Disasters in the Future
C．The Increase of Natural Disasters
D．Solutions to Natural Disasters

小題1:D
小題2:C
小題3:B
小題4:D
小題5:A

Below is a selection from a popular science book.
If blood is red, why are veins (靜脈) blue?
Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it's outside the body, when it's sitting in a vein near the surface of the skin, it's more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
Which works harder depends on whether you are busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don't they grow back in grown-ups?
Baby (or "milk") teeth do not last long; they fall out to make room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you're done. When they're gone, they’re gone. This is because nature figures you're set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn't because they're shrinking all over. They simply lose height as their spine(脊柱) becomes shorter and more curved due to disuse and the effects of gravity. Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don't really shrink! It is not that they are growing backwards — their legs, arms and backbones getting shorter. When they do get shorter, it's because the spine has shortened a little or, more often, become more bent and curved.
Why does spinning（旋轉(zhuǎn)） make you dizzy (眩暈的)?
Because your brain gets confused between what you're seeing and what you're feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you're moving while you're not!
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other newer bits of the brain, we feel more complex emotions than any other animal on the planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s "use it, or lose it”! It's not that exercise makes you healthy; it's more that a lack of exercise leaves your body weak and easily affected by disease.
小題1:What is the color of blood in a vein near the surface of the skin?
A．Blue. B．Light yellow.C．Red. D．Dark reddish purple.
小題2:Why do some old people look a little shrunken as they age?
A．Because their spine is in active use.
B．Because they are more easily affected by gravity.
C．Because they keep growing backwards.
D．Because their spine becomes more bent.
小題3:Which of the following statements about our brain is true?
A．In the long run, our brain probably works harder than our heart.
B．When our brain senses the spinning, we will fell dizzy.
C．The brains of the other mammals are as complex as those of humans.
D．Our feelings and emotions come from the most developed area in our brain.
小題4:What is the main purpose of the selection?
A．To give advice on how to stay healthy.
B．To provide information about our body.
C．To challenge new findings in medical research.
D．To report the latest discoveries in medical science.

We are fortunate to be living in a time when all people have the ability to access any knowledge they desire. This digital society that we live in affords us opportunities that our ancestor only dreamed of having. We should not take this privilege for granted.
In the not so distant past of the 1950s, people who wanted to research an idea, a product, or anything else, had to go to a library where they could look up information in books. Not all people had the same access to the books, and the information they contained. In America, if your skin was black, you could not use the same library that a person with white skin used. If a black skinned person was allowed access to a library, it most likely was stocked with outdated books that white skinned people had discarded.
In the digital society we live in today, the color of your skin does not determine the access you have to information. Technology has brought to us the powerful tools like the Internet where we can find information on almost every subject.
Access to the Internet has allowed us to research the things we are planning to purchase. We are capable of comparing prices on things like insurance, appliances, entertainment, clothing, and all other things. We also now have the ability to purchase items online without ever leaving our homes. We have been freed from the restrictions of store hours, and regional sales. A person in America can purchase a product from a person in Germany, without leaving home.
Because of the digital society we live in our children can learn about anything they are interested in. When they ask you what the dinosaurs ate, you can look it up, and tell them the answer. Because of this people will be smarter in the future, and technology will only improve.
小題1:By “We should not take this privilege for granted”, the writer means that ______.
A．we have special right to do anything
B．it is wrong to make use of the privilege
C．knowledge is important in the digital society
D．we should seize the chances the modern society offers
小題2:The main idea of the fourth paragraph is that ______.
A．the Internet brings us a lot of convenience
B．people in modern society are mostly wealthy
C．we would like to stay at home every day
D．we can find anything we like in the world
小題3:The dinosaurs are mentioned in the last paragraph in order to tell us that _____.
A．people will be much clever than ever
B．what the dinosaurs ate seems strange to us
C．finding out what the dinosaurs looked like is easy
D．we can learn knowledge with the help of technology
小題4:The writer’s attitude toward the digital society is ______.

Dogs can know the meaning of a human perspective, say researchers.
Dogs are more capable of understanding situations from a human's point of view than has previously been recognized, according to researchers.
They found dogs were four times more likely to steal food they had been forbidden, when lights were turned off so humans in the room could not see.
This suggested the dogs were able to alter their behavior when they knew their owners' perspective had changed.
The study, published in Animal Cognition, conducted tests on eighty-four dogs.
The experiments had been trying to find whether dogs could make their behavior suitable to react to the changed circumstances of their human owners. It wanted to see if dogs had a "flexible understanding" that could show they understood the viewpoint of a human.
It found that when the lights were turned off, dogs in a room with their human owners were much more likely to disobey and steal forbidden food.
The study says it is "unlikely that the dogs simply forgot that the human was in the room" when there was no light. Instead it seems as though the dogs were able to differentiate between when the human was unable or able to see them.
Juliane Kaminski carried out the research into how dogs are influenced by human circumstances.
Dr Juliane Kaminski, from the University of Portsmouth's psychology department, said the study was "incredible because it implies dogs understand the human can't see them, meaning they might understand the human perspective".
Previous studies have suggested that although humans might think that they can recognize different expressions on their dogs' faces, this is often inaccurate and a projection of human emotions.
“Humans constantly attribute(歸屬) certain qualities and emotions to other living things. We know that our own dog is clever or sensitive, but that's us thinking, not them,” said Dr Kaminski.
“These results suggest humans might be right, where dogs are concerned, but we still can't be completely sure if the results mean dogs have a truly flexible understanding of the mind and others' minds. It has always been assumed only humans had this ability.
小題1:According to the passage, which of the following is TRUE?
A．The researchers made the test on dogs in eighty-four countries.
B．Dogs always obey and don’t steal forbidden food.
C．Dogs may adapt their behavior in response to the changed circumstances.
D．The research is carried out to find out how dogs are influenced by light.
小題2:Which of the following can best serve as the title of the passage?
A．Dogs---Our Loyal Companions Understand Us Most.
B．Dogs Are Our Best Friends.
C．Dogs Can Understand Us In a Way, Researchers Say.
D．Dogs Have Certain Qualities and Emotions of Human Beings, Researchers Say.

Conservationists have unveiled plans to preserve and protect the world's most important species of coral, in a response to increasing threats that they say will lead to "functional extinction" within decades．
Led by scientists at the Zoological Society of London, the Edge Coral Reefs project has identified 10 coral species in most urgent risk of becoming extinct．The scientists say that reefs are under pressure from a variety of threats including rising sea temperatures due to climatic instability, increased acidity（酸性）, overfishing and pollution．
The Edge plan, which focuses on the most evolutionarily distinct and globally endangered species , will take a regional approach to conservation．This means focusing on the "coral triangle" around the Philippines, the West Indian Ocean around the Mozambique channel, and in the Caribbean channel．
"Coral reefs are threatened with functional extinction in the next 20-50 years, due predominantly to global climatic instability," said Catherine Head, coordinator of the reefs project．"In these regions, we'll be supporting and training in-country conservationists to carry out research and implement targeted conservation actions," she said．"Their projects will last initially for two years．We provide them with a whole host of tools to carry out their projects including funding and intensive training．" She added．
Coral reefs are the planet's most diverse marine ecosystem（生態(tài)系統(tǒng)）, known as the rainforests of the oceans．Despite taking up under 0．2% of the ocean floor, they provide food and shelter for almost a third of all sea life．If we lose the ecosystems, we lose not only the biodiversity （生物多樣性）, but we also lose the capability of people to obtain income and food from coral reefs．
Climatic instability, which leads to rising sea temperatures, causes corals to bleach．Bleaching occurs when sea temperatures rise and this causes the coral tissue to expel their symbiotic algae called zooxanthellae - these are what give the coral their colour．Bleached corals often die if the stress continues．Among the 10 species chosen to start the Edge project are the pearl bubble coral, a food source for the hawksbill（玳瑁）turtle, and the Mushroom coral, which supports at least 15 brightly colored fish．
小題1:What does the first paragraph mean in the passage ?
A．Conservationists planned to preserve and protect some extinct corals years ago．
B．Conservationists have banned plans to protect endangered corals for years．
C．Conservationists are going to protect corals that are dying out in several ten years．
D．Conservationists have made plans to protect corals from being extinct in ten years．
小題2:What will probably happen to coral species with the increasing threats?
A．Decrease．B．Losing functions
C．Disappearance．D．Existence
小題3:Which of the following statements about the Edge Plan is TRUE?
A．The Edge Coral Reefs project was carried out by American scientists．
B．The plan concentrates on the channels to protect the endangered species．
C．The Conservationists have carried out the Edge plan for many years to protect the corals．
D．Ten coral species chosen by the project are at the greatest risk of becoming extinct．
小題4:Which of the following will be the consequence of coral extinction in the passage?
A．We will keep the balance of the marine ecosystems．
B．About one third of the marine species can't survive．
C．Man can benefit more from corals．
D．We will lose the rainforests on our earth．
小題5:What is the best title of the passage?
A．Climatic Instability and Coral Extinction
B．Reasons for Coral Functional Extinction．
C．A Plan to Save Coral from Extinction

Tre’S mom，Christina Thompson, cannot believe how much her son already learned this year in his full-day, free pre-school class in Oklahoma City. “Since he’s been in school his vocabulary has increased surprisingly,” Thompson says. “The other day he came home and said, ‘You know what ，mom? You are being ridiculous，” Thompson laughs quietly. “And then he asked, ‘Do you know what ‘ridiculous’ means, mom?’” Tre knows the entire alphabet, his numbers to 100，and he’s starting to read. And letters and numbers aside, Thompson is most struck by how fast Tre is absorbing vocabulary and language.
Of course, not all pre-school is created equal. High quality pre-schools have well-trained, well-educated teachers in the classroom (much like Tre Thompson’s teacher Mrs. Wallace, who uses play-based learning to teach both academics and social skills and can rattle off (飛快說出） a battery of data on how well her students are progressing towards their year-end goals). Texas can also offer a model for educator development: its Texas School Ready! Campaign has proven to increase the quality of participating pre-schools by providing early childhood teachers with coaching, professional development, research-based curriculum (課程)，and progress monitoring. States and districts should also combine pre-school with the K-12 system, as Oklahoma does ，so that children enter kindergarten smoothly.
Oklahoma is one of the leading states in providing students like Tre with free ，full-day pre-school. And the results are already paying off: According to a 2012 study, Oklahoma kids that went through pre-school showed vocabulary gains 28% higher than those of children without pre-school, and math gains 44% higher than non-pre-school kids. And we know that high-quality pre-school doesn’t just mean higher scores in elementary school. They were more likely to have graduated from high school and less likely to have committed a violent crime. They also earned more money and were more likely to be employed.
We know pre-school works, so let’s stop talking and start building a system where all children have access to excellent early childhood education. As any well-educated four year old could tell us, not doing so would be ridiculous.
小題1:The case of Tre in the first paragraph serves as the evidence of______.
A．children’s disrespect towards parents
B．the bad performance of students at school
C．the positive effect of pre-school on children
D．Thompson’s doubt about her son’s education
小題2:At high quality pre-schools, children may learn by______
A．playingB．modellingC．researchingD．monitoring
小題3:It can be inferred that______.
A．children can not enter kindergarten without pre-school
B．Oklahoma is the best state offering full-day pre-school
C．a(chǎn)ll pre-schools have well-trained, well-educated teachers
D．kids with pre-school may be better equipped for their future
小題4:What would be the best title for the passage?
A．Not all pre-school works
B．All pre-school is created equal
C．We owe our kids universal pre-school
D．Pre-school goes well with K-12 system

Pupils remember more and behave better when 3D images are used in lessons, research suggests. They are quicker to learn and absorb new concepts, and display higher levels of concentration.
Professor Anne Bamford, of the University of the Arts, London, studied the effectiveness of 3D content in 15 schools across seven countries, including the UK. Pupils in 3D classes could remember more than those in the 2D classes after four weeks, improving test scores by an average 17 percent compared with eight percent for 2D lessons. They gave more detailed answers to the tasks and were more likely to think in 3D, using hand gestures and mime (模仿動作) to answer the test questions successfully.

The teachers commented that the pupils in the 3D groups had deeper understanding, increased attention span, more motivation and higher engagement in the lessons
Children are used to 3D with the rise of computer games that use the technology—90 percent of those in the study had seen a 3D film. Schools would need 3D-enabled projectors（投影儀）, laptops with good picture capabilities, 3D software and glasses for children to introduce animations (動作) into classrooms.
But Danny Nicholson, an educationist, said the technology would be impractical to use in schools and could be too expensive. He said,“While I think the idea of 3D technology is very interesting, I worry that 3D is a bit of an expensive gimmick (小玩意兒). There are a few cases where a true 3D image might help, but most of the time, good 2D models that can be moved , would be just so effective.”
In Colorado, the US, one school district is already in the process of having 1,000 3D projectors fixed in classrooms. And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils. Those who watched the 3D presentations were more engaged and reported a general increase in their interest in science compared with students who watched the 2D version.
小題1:Teachers think pupils in 3D classes      .
A．a(chǎn)re naughtier than those in 2D classesB．have less motivation
C．find it hard to concentrateD．have deeper understanding
小題2:Danny Nicholson tends to think that      .
A．many pupils prefer 2D models
B．3D is a bit expensive for some schools
C．true 3D images would not help in classes
D．3D technology has a bright future in classes
小題3:What can we learn from the last paragraph?
A．3D classes will soon be given in one school district in Colorado.
B．Teachers will use the 3D technology through specific training.
C．Many pupils are now more interested in science than before.
D．3D technology will replace 2D models in the future.
小題4:What is the text mainly about?
A．2D models are always more effective than 3D images.
B．The differences between 3D and 2D images.
C．How schools can make full use of 3D technology.
D．Pupils behave better when 3D images are used in classes.
小題5:Where is the text most probably taken from?
A．A history book.B．A news story
C．A science magazine.D．A school report.
