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 21 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 six­week period in July and August 2008，more than 11400 — 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(qiáng)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 air­conditioners installed in elderly care homes. But this is considered a short­term solution, as the increase in demand for electricity also increases carbon emissions.
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 air­conditioner.
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 coal­fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.
【小題1】Which of the following would be the best title for the passage?

A．Big Cities Facing Big DisastersB．Big Disasters in the Future
C．The Increase of Natural DisastersD．Solutions to Natural Disasters
【小題2】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3】 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 air­conditioners installed in elderly care homes.
C．Forbidding the city to build “Flower Tower”.
D．Encouraging architects to design new types of buildings.
【小題4】The major threats to Shanghai are ________.
A．increasing population and coal­fired 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5】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

Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affect sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels（分貝）measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
Some scientists have proposed setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud noises can seriously injure some animals. The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected.
Many researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists suspect that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
【小題1】According to the passage, which of the following is increasingly dangerous to sea creatures?

A．The man-made noises.
B．The noises made by themselves.
C．The sound of earthquakes.
D．The sound of the ice-breaking.
【小題2】As to the influence of noises on whales, which of the following statements is true?
A．They are deaf to noises.
B．Noises at a certain level may hurt them.
C．They are easily confused by noises.
D．Noises will limit their ability to reproduce.
【小題3】 We can know from the passage that many scientists think that the noise limit of one hundred twenty decibels would______.
A．prevent them from doing their research work
B．benefit them a lot in their research work
C．do good to their health
D．increase the industrial output
【小題4】According to the passage, what will scientists most probably do in the future?
A．They will try their best to decrease noise.
B．They will work hard to cut down noise pollution.
C．They will study the effect of different noises.
D．They will protect animals from harmful noises.

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 colour. 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?
That kind of question 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 tunes 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 do. 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 (重力). 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 bait and curved.
Why does spinning 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 Dot!
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 lost 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 colour of blood in a vein near the surface of the skin?
A．Blue.  B．Dark reddish purple. 
C．Red.  D．Light yellow. 
【小題2】Why do some old people look a little shrunken as they age?
A．Because they are more easily affected by gravity. 
B．Because their spine is in active use. 
C．Because their spine becomes more bent. 
D．Because they keep growing backwards. 
【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 challenge new findings in medical research. 
C．To report the latest discoveries in medical science. 
D．To provide information about our body.

About ten men in every hundred suffer from color blindness in some way. Women are luckier, only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man can not see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods” but these are used for seeing when it is nearly dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes (蚊子) like blue but do not like yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible (看不見(jiàn)的) colors around.
【小題1】Why do some people say it is safer to be driven by women?

A．Women are more careful.
B．There are few color-blind women.
C．Women are fonder of driving than men.
D．Women are weaker but quicker in thinking
【小題2】This passage is mainly about ________.
A．color and its surprising effects
B．women being luckier than men
C．danger caused by color blindness
D．color blindness
【小題3】According to the passage, with the help of the “cones”， we can ________.
A．tell orange from yellow
B．see in weak light
C．kill mosquitoes
D．tell different shapes
【小題4】We can attract and kill mosquitoes by using a ________.
A．red light B．yellow light C．blue light D．green light

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.
【小題1】We can infer from the text that humans and animals ____.

A．depend on one sense in choosing food
B．a(chǎn)re not satisfied with their food
C．choose food in similar ways
D．eat entirely different food
【小題2】Which of the following eats only one type of food?
A．A white butterfly.B．A small bird.
C．The bear.D．The fox.
【小題3】Certain animals change their choice of food when ____.
A．the season changes
B．the food color changes
C．they move to different places
D．they are attracted by different smells
【小題4】We can learn from the last paragraph that ____.
A．food is chosen for a good reason
B．French and British food is good
C．some people have few choices of food
D．some people care little about healthy diet
【小題5】What will most probably be talked about in the next paragraph?
A．Why choosing the right food is important.
B．How to choose the right food.
C．The right amount of food for a person.
D．Vegetables matter more than meat and sugar.

Do you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s. Since researches have shown that the bigger the brain, the cleverer the animal, men must be more intelligent than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain consists of “grey matter” and “white matter”. While men have more of the latter, the amount of “thinking” brain is almost exactly the same in both sexes.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes. As white matter is the key to spatial(空間的) tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries—why men refuse to ask for directions … and women often need to!
The differences begin when fetuses(胎兒) are about nine weeks old, which can be seen in the action of children as young as one. A boy would try to climb a barrier (障礙物) before him or push it down while a girl would attract help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research. www. .com
If all this disappoints you, it shouldn’t. “The brain changes throughout our lives according to what we do with it.” says a biologist.
【小題1】Which of the following is true according to the first paragraph?

A．Women’s brain is 10% less than men’s
B．Grey matter plays the same role as white matter.
C．Grey matter controls thinking in the brain.
D．Both sexes have the same amount of white matter.
【小題2】What can we infer from the second and third paragraphs?
A．Women prefer doing many things at a time.
B．Men do better dealing with one job at a time.
C．Women do not need to tell directions.
D．Men have weaker spatial abilities.
【小題3】Which of the following do you agree with according to the fourth paragraph?
A．Young boys may be stronger than young girls.
B．More women take up jobs requiring speech skills.
C．Women may have stronger feelings than men.
D．Our ancestors needed more spatial skills.

For the people living in the Nile Basin, the river is their life．This 6,825 km waterway, whose watershed（流域）covers three million square kilometers, flows through mountains ,woodlands, lakes and deserts．Its potential for fishing, tourism and shipping is great—but so are its challenges. 
Water shortage , already serious in Egypt and Sudan , will soon influence several other countries in the watershed as well．Today, about 160 million people depend on the Nile River for their living．Within the next 25 yeas ,the district's population is expected to double, adding to the demand brought about by growth in industry and agriculture．The frequent drought（干旱）adds to the urgency.
Water quality is also a problem．Precious soil is washed out to sea．Wastes from industry and agriculture create pollution．Higher concentrations of salt influence irrigated soils．Water-borne diseases continue unchecked．In areas where it's hot and damp, water hyacinths choke off（阻止） lakes, dams and other sections of the river, making it difficult for fishing and other businesses to move forward.
Native people along the narrow area of farmland have watched the sand move closer day by day．They’ve seen the river change course, and their only source（來(lái)源） of water thickened with mud．They’re very poor and have few choices.
But a new program, the Nile Basin Initiative (NBI), is offering very practical assistance．The program is more than just a water-management project．It’s a plan for the social and economic development of a vast district: it concentrates on the needs of the poorest of the poor and the environment that supports them.
These are whole ecosystem problems, calling for united solutions．Half the Nile Basin's countries are among the world's poorest nations；yet, somehow, they must find the resources, skills and political will to overcome these challenges.

The United States is full of cars. There are still many families without cars, but some families have two or more. However, cars are used for more than pleasure. They are a necessary part of life.
Cars are used for business. They are driven to offices and factories by workers who have no other way to get to their jobs. When salesmen are sent to different parts of the city, they have to drive in order to carry their products. Farmers have to drive into the city in order to get supplies.
Sometimes small children must be driven to school. In some cities school buses are used only when children live more than a mile away from the school. When the children are too young to walk too far, their mothers take turns driving them to school. One mother drives on Mondays taking her own children and the neighbors' as well. Another mother drives on Tuesdays, another on Wednesday, and so on. This is called forming a car pool. Men also form car pools, with three or four men taking turns driving to the place where they all work.
More car pools should be formed in order to put fewer cars on the road and use less gas. Too many cars are being driven. Something will have to be done about the use of cars.

How long you live has a lot to do with your environment and lifestyle, but exceptional(特別的)long life may have even more to do with your genes. For the first time, researchers have discovered a genetic recipe(基因譜)that accurately predicts who may live to 100 and beyond.
Analysis shows that 90% of the participants who lived to 100 had at least one of the signature genetic clusters(標(biāo)志基因組). Dr. Thomas Perls at the Boston University School of Medicine said, “We realize this is a complex genetic puzzle. There is a long way for us to go to understand how the integration(融合)of these genes—not just with themselves but with environmental factors—is playing a role in this long life puzzle.”
Perls has studied many factors that contribute to long life, and he is the first to acknowledge that living longer isn’t likely to be simply a matter of genes. His previous work has shown, for example, that among most elderly people who live into their 70s and 80s, about 70% can owe their long life to environmental factors such as not smoking; eating a healthy, low-fat, low-calorie diet; and remaining socially engaged and mentally active throughout life.
It seems clear that those who live extremely long are benefiting from a special DNA. In fact, Perls believes that the older a person gets, the more likely it is that his or her genes are contributing to those extended years.
【小題1】Which of the following is TRUE according to Paragraph 2?

A．Most long-living people have special long-life-related genes.
B．Ninety percent of the participants lived to 100 years of age.
C．All the long-living people have only one signature genetic cluster.
D．Scientists know how the integration of the genes helps people live long.
【小題2】 Perls may most likely agree that         .
A．most people living extremely long benefit from not smoking
B．living longer just depends on certain genetic recipes
C．environmental factors play an important role in long-living
D．being mentally active has nothing to do with living an old age
【小題3】 Which of the following is FALSE according to the text?
A．Remaining socially engaged helps a person to live long.
B．A genetic recipe can accurately predict who may live to 100 and beyond.
C．Perls is the first to think living longer is just a matter of genes.
D．The older he gets, the more likely the genes contribute to his extended years.
【小題4】Which of the following would be the best title for the text?
A．Genes May Predict Who Lives to 100 B．Environment And Genes
C．Genes, the Secret of Long Living D．Lifestyle And Genes
