“In wilderness(荒野) is the preservation of the world.” This is a famous saying from a writer regarded as one of the fathers of environmentalism. The frequency with which it is borrowed mirrors a heated debate on environmental protection: whether to place wilderness at the heart of what is to be preserved.  
As John Sauven of Greenpeace UK points out, there is a strong appeal in images of the wild, the untouched; more than anything else, they speak of the nature that many people value most dearly. The urge to leave the subject of such images untouched is strong, and the danger exploitation(開發(fā)) brings to such landscapes(景觀) is real. Some of these wildernesses also perform functions that humans need—the rainforests, for example, store carbon in vast quantities. To Mr. Sauven, these “ecosystem services” far outweigh the gains from exploitation.
Lee Lane, a visiting fellow at the Hudson Institute, takes the opposing view. He acknowledges that wildernesses do provide useful services, such as water conservation. But that is not, he argues, a reason to avoid all human presence, or indeed commercial and industrial exploitation. There are ever more people on the Earth, and they reasonably and rightfully want to have better lives, rather than merely struggle for survival. While the ways of using resources have improved, there is still a growing need for raw materials, and some wildernesses contain them in abundance. If they can be tapped without reducing the services those wildernesses provide, the argument goes, there is no further reason not to do so. Being untouched is not, in itself, a characteristic worth valuing above all others.
I look forward to seeing these views taken further, and to their being challenged by the other participants. One challenge that suggests itself to me is that both cases need to take on the question of spiritual value a little more directly. And there is a practical question as to whether wildernesses can be exploited without harm.
This is a topic that calls for not only free expression of feelings, but also the guidance of reason. What position wilderness should enjoy in the preservation of the world obviously deserves much more serious thinking.
小題1:John Sauven holds that________________.
A.many people value nature too much
B.exploitation of wildernesses is harmful
C.wildernesses provide humans with necessities
D.the urge to develop the ecosystem services is strong
小題2:What is the main idea of Para. 3?
A.The exploitation is necessary for the poor people.
B.Wildernesses cannot guarantee better use of raw materials.
C.Useful services of wildernesses are not the reason for no exploitation.
D.All the characteristics concerning the exploitation should be treated equally.
小題3:What is the author’s attitude towards this debate?
A.Objective.B.Disapproving.C.Sceptical.D.Optimistic.
小題4:Which of the following shows the structure of the passage?
A.B.C.D.

Can you remember a morning when you’ve woken up to the ring of your alarm clock and wished you could stay in bed? You haven’t slept well, your hair is a mess. Worse, you can’t stop yawning. Yawning is universal to humans and many animals. Cats, dogs and fish yawn just like humans do! Yawning is an involuntary(無意識的,不自覺的) action during which you open your mouth and breathe deeply. The average duration of a yawn is about 6 seconds.
The purpose and cause of yawning are still a mystery. Scientists are not sure what causes a yawn. People yawn when they are tired or bored, but they also yawn when they aren’t. There are many ideas explaining why we yawn.
One idea is that yawning is a way for the body to become more alert by taking in more oxygen. A yawn increases the heart rate, forces carbon dioxide out of the lungs and blood stream, and brings oxygen to the brain. But one study showed that volunteers given a lot of oxygen did not yawn any less than before, while those given a lot of carbon dioxide did not yawn more.
Another idea is that early humans used yawning as a form of communication. If one decided it was time to sleep, they would tell the others by yawning and they would do it in return to show they agreed.
A third explanation comes from psychology professor Gordon Gallup of University at Albany in New York. He said that as people yawn, they cool off their brains. “Brains are like computers.” he said. “They only operate efficiently and effectively when they’re cool. Many things connected to yawning, like being tired, make the brain hot, and yawning can reduce the heat.”
Scientists have sent people into space, and created terrible nuclear weapons, but there are lots of seemingly simple things, such as why we yawn, or hiccup(打嗝), that they can’t figure out. Next time you are in class in the morning, let out a big yawn and watch to see how many of your classmates yawn in response!
小題1:What’s the purpose of the description of how bad you may feel when you’re woken up in the morning?
A.To explain why humans yawn.
B.To explain how humans start yawning.
C.To lead into the topic of yawning.
D.To complain about being woken up by the clock.
小題2:Which is not among the possible reasons for yawning mentioned in the passage?
A.A way to show that you feel hot.
B.A way to get rid of carbon dioxide.
C.A way to cool off your brain.
D.A way to communicate.
小題3:In which situation are you likely to yawn?
A.When you feel frustrated.
B.The weather is hot.
C.Someone else yawns near you.
D.When you breathe in a lot of carbon dioxide.
小題4:What can we learn from the passage?
A.The real reason why humans and most animals yawn.
B.Hiccups are an involuntary human action similar to yawns.
C.The more an action can be studied, the easier it is to research.
D.Finding out why humans yawn should be easier than sending people into space.

Botany (植物學(xué)) , the study of plants, occupies a particular position in the history of human knowledge.For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest (模糊的)) of insights.It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient.This is logical.Plants are the basis of the food pyramid for all living things even for other plants.They have always been enormously important to the welfare of people not only for food but also for clothing, tools, medicines, shelter, and a great many other purposes.Tribes living today in the jungle of the Amazon recognize hundreds of plants and know many properties of each.To them, botany has no name and is probably not even recognized as a special branch of "knowledge" at all.
Unfortunately, the more industrialized we become, the farther away we move from direct contact with plants, and the less distinct our knowledge grows.Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose or an apple.When nor Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer fields the next season—the first, great step in a new association of plants and humans was taken.Grains were discovered and from them flowed the wonder of agriculture: cultivated crops.From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild, and the accumulated knowledge of tens of thousands of years of experience with plants in the wild would begin to fade away.
小題1:What does the writer mean when he says "This is logical" in the first paragraph?
A.Human knowledge of plants is well organized and very detailed.
B.It is not surprising that early humans had a detailed knowledge of plants.
C.There is no clear way to determine the extent of our ancestor's knowledge of plant.
D.It is reasonable to assume our ancestors behave much like people in pre-industrial societies.
小題2:According to the passage, general knowledge of botany begun to fade away because ____.
A.people no longer value plants as a useful resource
B.direct contact with a variety of plants has decreased
C.botany is not recognized as a special branch of science
D.research is unable to keep up with the increasing number of plants
小題3:We learn that the first great step toward the practice of agriculture is____.
A.the changing diets of early humans
B.the development of a system of names for plants
C.the invention of agricultural implements (工具) and machinery
D.the discovery of certain grasses that could be harvested and replanted
小題4:Human would depend on the controlled production of a few plants for living with
A.the knowledge of plants
B.the discovery of certain grasses
C.the development of machinery
D.the appearance of agriculture

The world is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can’t drink or use for watering plants directly. Man can only drink and use the 3% the water that comes from rivers and lakes. And we can’t even use all of that, because some of it has been polluted.
Now more water is needed. The problem is: can we avoid a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out the ways to reuse it. Scientists have always been making study in this field. Today, in most large cities water is used only once and then runs to the sea or rivers. But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next?
The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it’s already in use in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we’ll be in no danger of drying up.
小題1:The world is thirsty because ___________.
A.3/4 of the earth is covered with water
B.we have enough sea water
C.we haven’t used all the water in rivers and lakes
D.a(chǎn)bout 97% of water on the earth can’t be drunk or used for watering plants directly
小題2:Which of the following is TRUE?
A.3% of drinkable water on the earth is from rivers and lakes.
B.75% of water on the earth is in the sea.
C.97% of the earth is covered with water.
D.3% of water on the earth is sea water.
小題3:From the passage we learn that __________.
A.if every city reuses its water, we’ll be in no danger of drying up
B.man can only drink and use about 25% of water on the earth
C.today in most large cities water is used only once
D.water can be used only once

Too many people want others to be their friends, but they don’t give friendship back. That is why some friendships don’t last very long. To have a friend, you must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous (寬宏大量的);be understanding.
Honesty is where a good friendship starts. Friends must be able to trust one another. If you don’t tell the truth, people usually find out. If a friend finds out that you haven’t been honest, you may lose your friend’s trust. Good friends always count on one another to speak and act honestly.
Generosity means sharing and sharing makes a friendship grow. You don’t have to give your lunch money or your clothes, or enjoy, like your hobbies and your interests. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them you help your friend know you better.
Sooner or later everyone needs understanding and help with a problem. Something may go wrong at school. Talking about the problem can make it easier to solve . Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend’s place so you can understand the problem better.
No two friendships are ever exactly alike (相同). But all true friendships have three things in common. If you plan to keep your friendships, you must practice honesty, generosity and understanding.
小題1:Some friendships don’t last very long because       .
A.there are too many people who want to make friends.
B.they don’t know friendship is something serious
C.they receive others’ friendships but never give others friendships
D.they always give other people friendships

A.a(chǎn)s important as moneyB.more important than anything else
C.something countableD.the base of a friendship
小題3:Which of the following is NOT true in the passage?
A.A friend who gives you his lunch money is a true friend.
B.Always tell your friend the truth.
C.Discussing your problems with your friend often helps to solve the problem.

The ability to memorize things seems to be a vanishing (消失的) technique.So what can we do to bring out brain cells back into action? A newly published book on memory, Moomvalking with Einstein: The Art and Science of Remembering Everything, by American journalist Joshua Foer, makes a telling point, one that is an analysis of the importance of memorising events and stories in human history; the decline of its role in modem life; and the techniques that we need to adopt to restore the art of remembering.
As For points out, we no longer need to remember telephone numbers.Our mobile phones do that for us.We don't recall addresses either.We send emails from computers that store electronic addresses.Nor do we bother to remember multiplication tables (乘法表) .Pocket calculators do the job of multiplying quite nicely.Museums, photographs, the digital media and books also act as storehouses for memories that once we had to keep in mind.
As a result, we no longer remember long poems or folk stories by heart, feats (技藝) of memory that were once the cornerstones of most people's lives.Indeed, society has changed so much that we no longer know what techniques we should employ to remember such lengthy works.We are, quite simply, forgetting how to remember.
And let's face it, there is nothing sadder than someone who has lost their mobile phone and who finds they cannot even phone home or call their parents or partners because they cannot remember a single telephone number.That is a sad example of loss of personal independence.So, yes, there is a need for us to he able to remember certain things in life.
Therefore, Foer's book outlines the methods that need to be mastered in order to promote our memories and regain the ability to recall long strings of names, numbers or faces.In the process, he adds, we will become more aware of the world about us.
The trick, Foer says, is to adopt a process known as " elaborative encoding", which involves transforming information, such as a shopping list, into a series of "absorbing visual images".If you want to remember a list of household objects—potatoes, cottage cheese, sugar and other items, then visualise them in an unforgettable manner, he says.Start by creating an image of a large jar of potatoes standing in the garden.Next to it, imagine a giant tub of cottage cheese—the size of an outdoor pool—and then picture Lady Gaga swimming in it.And so on.Each image should be as fantastic and memorable as possible.
Using methods like this, it becomes possible to achieve great feats of memory quite easily, Foer says.It certainly seems to have worked for him: he won the annual US Memory Championships after learning how to memorize 120 random digits in five minutes; the first and last names of 156 strangers in 15 minutes; and a deck of cards in under two minutes."What I had really trained my brain to do, as much as to memorise, was to be more mindful and to pay attention to the world around," he says.
These techniques employed by Foer to master his memory were developed by Ed Cooke—a British writer and a world memory championship grandmaster.He acted as Foer's trainer during preparations for the book and helped him achieve his championship performances." Memory techniques do just one thing: they make information more meaningful to the mind, making the things we try to learn unforgettably bright and amusing," said Cooke.
小題1:Which of the following is conveyed in this article?
A.People become more independent with modern equipment.
B.The memory's role in life is declining in modem society.
C.Memory techniques can make information less meaningful.
D.Ed Cooke is the first one who benefited from Foer's techniques.
小題2:According to Joshua Foer, people no longer memorize information today because________.
A.museums can do everything for them.
B.they no longer have the ability to memorize things.
C.they have things that can act as storehouses for memories.
D.it is not necessary to memorize anything in modem life.
小題3:One method of memorizing things mentioned in the passage is to ________.
A.link things to famous pop stars
B.find the connection between different things
C.form vivid, unforgettable images of certain things
D.use advanced digital imaging technology to help
