A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely falling below 16℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.
In the past hundred years, humans have begun destroying rainforests in search of three major resources : land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.    There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.
【小題1】 Rainforests can help to adjust the climate because they________.

A.reflect more heat into the atmosphere
B.bring about high rainfall throughout the world
C.rarely cause the temperature to drop lower than 16℃
D.a(chǎn)bsorb the heat from the sun, reducing the effect of heat from the sun on the earth

One of my main concerns when I am helping people achieve their goals is how they measure success. I see individuals getting frustrated as they struggle hard for success.
One of the main reasons that cause this frustration is that people allow their definition of success to be determined by someone or something else. Another is that they become frustrated at their own apparent lack of success when comparing themselves to other people.
We are individuals with individual wants, skills and experiences. We should look at our own skills to determine what is successful to us. We should look inwards to determine what it would mean for us to be successful in our own mind rather than someone else’s.
Evaluating a successful person needs to look at his pathway to success, his actions ,his determination and translate that into his own experience to see how he can improve himself.
You must set your own course of action, and stay on your course. You alone must determine what success means to you. Do what you do to the best of your ability and the rest will take care of itself. For example, I believe that I am successful but I am not a millionaire! Others may not see me as successful in their eyes but that does not matter. It is how I see myself that is important to me and my life.
Here is the truth. Being a success is doing your best, not being the best. Success is not something you become; it is something you continue being.
When we get to that point, we will experience a lot more joy and a lot less frustration. And that sounds good to us!
Remember the great quote from Napoleon Hill, “If you cannot do great things, do small things in a great way.”
【小題1】What’s the best title of this passage?

A.Frustration Determines Success
B.The Importance of Frustration to Success

A.struggle too hard B.know little about others
C.a(chǎn)re often discouraged D.underestimate themselves
【小題3】Which is NOT true according to the passage?
A.Success is something you keep on being rather than you become.
B.Evaluating a successful person needs to look at others’ judgment.
C.It doesn’t matter others may not consider you as a success in their eyes.
D.It matters that you set your own course of action and stay on it.
【小題4】According to the passage the writer advises us to_____.
A.a(chǎn)ttach the importance to others’ attitude and evaluation
B.learn from others ,failure
C.set a proper goal and strive to realize it
D.look at others’ skills to determine what is successful to us

I guess I always knew about the little fish treat, but this past summer it was all I could see. Pipin and Nemo were balancing on one front flipper(鰭), flying through hoops, dancing with the trainer, and we were all applauding — the little kids screaming with delight. That’s when the trainer, who wore a little treat bag on her belt, slipped Pipin and Nemo a fish. Each time they successfully performed a trick, they’d get an immediate reward.
These creatures weren’t really dancing, of course. They were performing a series of movements that they knew would produce a fish. It’s such a good show because the sea lions look like they’re having such fun. These talented performers who love to be in front of an audience seem almost human.
Somewhere in our faith journey, we all have a sea lion moment. You see how you’ve spent years jumping through hoops, balancing a ball on your nose, not because it’s really who you are, but because you’ve always done it and the system rewarded you for your performance. But when you’ve done that for ten or twenty years, you start to ask yourself, “Whose approval am I working for? What do I really believe?” Suddenly you see it: you’ve spent most all your life taking direction from other people. They’ve told you what to believe in, what to work for, what to value, how to live your life. You don’t want to end your life like Sinclair Lewis’s George Babbitt, the middle-aged real-estate broker(經(jīng)紀人) who has everything and reached the top. But on the last page of Babbitt, George is speaking to his son Ted, who cannot follow in his father’s steps. He wants to leave college and head off on his own way. “Dad, I can’t stand it any more,” the boy says. “Maybe it’s all right for some fellows. Maybe I’ll want to go back some day, but now, I want to get into mechanics.” Babbitt, seeming old and subdued, says, “I’ve never done a single thing I’ve wanted to in my whole life!”
The Good-Bye Gate brings us naturally to a second passage, leading from dependency to self-possession. As you start separating from the whole worn-out system, you discover that where there is supposed to be a self, there really isn’t.
【小題1】The sea lions were pleased to perform in front of the audience because they ____.

A.will be punished if it refuses it
B.wants to win the trainer’s favor
C.wants to get audiences’ applauses
D.can get food as a reward that way
【小題2】While watching the sea lions’ performance, the author ____.
A.realized an important life philosophy
B.recalled the similar scene of last year
C.couldn’t help shouting and dancing
D.was happy to see them living freely
【小題3】By saying “we all have a sea lion moment”, the author means that ____.
A.a(chǎn)nyone can make it so long as they work hard
B.sometimes we don’t act following our own will
C.we can also get rewarded if we do something well
D.every human being also has his happy moment
【小題4】What do you learn about George Babbitt?
A.He has been living a free life of his own.
B.His son ends up Babbitt family’s business.
C.He tends to agree to his son’s choice of life.
D.His son decides to follow his father’s steps.

People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. “Today we’re looking at science fiction becoming tomorrow’s reality—the driverless car.” The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the US government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
“Cars have become much more fuel-efficient, and new electronic features are making Hondas safer,” said Angie Nucci of Honda America. “A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes.” Other safety features include warning systems on the front and the sides of the cars. These systems help drivers, but don’t replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.
“By taking out drivers, you also remove most risks of an accident,” Kendall said. He said consumers, however, may be unwilling to lose control. “It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first.”
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.
【小題1】What can we learn from Paragraph l?
A. Volvo will be the first to sell driverless cars.      
B. Driverless cars are pointing us a faraway future.
C. Driverless vehicles are now legal in the whole USA.
D. Google’s self-driving cars have covered a long distance.
【小題2】We learn that Governor of California Jerry Brown_________.

A.helped design self-driving cars
B.supports self-driving cars on roads
C.considers self-driving cars science fiction
D.improved the self-driving car systems
【小題3】According to Richard Mason, what is the biggest challenge for driverless cars?
A.They are not allowed to run on the road.
B.Their technical problems remain to be solved.
C.They are now too expensive for consumers.
D.They are more dangerous for people on the street.
【小題4】Which is the best title for the passage?
A.The Benefits of the Self-driving Cars
B.The Biggest Challenge of the Self-driving Cars
C.Safer or More Dangerous Self-driving Cars
D.Self-driving Cars—Science Fiction Future Is Near

One reaction to all the concern about tropical deforestation(毀林) is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"
The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.
Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.
Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.
Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.
Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realise the severe effects of tropical deforestation, it will be 20 years too late.
Can tropical deforestation affect our everyday lives? Now, you should have got the answer.
【小題1】The underlined word "synthetics" probably means_________.

A.natural rubber B.tropical materials
C.man-made material D.commercial rubber
【小題2】According to the passage, which of the following is NOT true?
A.The forests are losing their function in turning carbon dioxide into oxygen.
B.Many of our daily uses are related to the tropical forests.
C.Tropical plants can be used to make industrial products.
D.High carbon dioxide levels will make the earth warmer.
【小題3】The author's attitude towards the tropical deforestation is _________ .
A.puzzling B.cold
C.supporting D.opposed
【小題4】Which of the following might be the best title for the passage?
A.Tropical Forests B.The Value of Tropical Forests
C.Tropical Forests and Our Life D.The Greenhouse Effects

Europe is now the biggest market for organic food in the world, having grown by 25 percent a year over the past 10 years. Denmark’s agriculture minister is herself an organic farmer. The UK market for organic food grew by 55 percent in 2000, while the food market as a whole grew by only one percent. Yet only seven percent of British shoppers account for nearly 60 percent of organic sales. However popular the idea of organic farming may be, it is still an interest for only a few people.
So what makes the idea of organic farming popular? Organic farming means farming with natural materials, rather than with man-made fertilizers or pesticides(殺蟲劑). Organic farmers rely on many methods — such as crop rotation (農(nóng)作物的輪作) and the use of resistant(有抵抗力的)varieties, because they are necessary for organic farmers to compensate for the shortage of man-made chemicals.
Organic farming is often supposed to be safer than traditional farming for the environment. Yet after a long research on organic farming worldwide for a number of years, science continues to be against this opinion. The House of Commons committee on agriculture stated that, even with complete research work, it would fail to find any scientific evidence to prove “that any of claims made for organic farming is always true”.
However, the talk about the benefits of organic farming is going on. This is partly because many people depend on their individual farm, the soil, the weather, and so on.
【小題1】The first paragraph mainly tells us _________.

A.organic farming has been performed only in Europe over the past 10 years.
B.governments of European countries have cared less about organic farming.
C.organic farming isn’t so popular as expected.
D.European countries need organic food more than the other countries in the world.
【小題2】The underlined words “compensate for” in the second paragraph probably mean “_________”.
A.a(chǎn)rgue forB.care for
C.make up forD.pay for
【小題3】 What can we know about organic farming?
A.It refers to farming with natural materials, instead of chemical fertilizers.
B.It refers to farming with chemical fertilizers rather than natural fertilizers.
C.It refers to farming with soil rather than any other thing.
D.It refers to growing crops with man-made fertilizers and pesticides.
【小題4】According to the third paragraph, _________.
A.organic farming is safer than traditional farming for the environment.
B.the idea that organic farming is safer has not been proven by science.
C.organic farming is accepted by the UK’s House of Commons committee.
D.organic farming is preferred to traditional farming.
【小題5】Which of the following is TRUE, according to the passage?
A.The UK’s agriculture minister is an organic farmer.
B.Organic farming is popular with young people.
C.Farmers try every means to improve the organic sales system.
D.Ninety-three percent of British shoppers don’t buy organic products.

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 depends on whether you’re 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 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-up?
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(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 bent 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 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 animals 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 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 their spine become more bent.
B.Because they are more easily affected by gravity.
C.Because they keep growing backwards.
D.Because their spine is in active use.
【小題3】Which of the following statements about our brain is true?
A.The brains of the other mammals are as complex as those of humans.
B.When our brain senses the spinning, we will feel dizzy.
C.In the long run, our brain probably works harder than our heart.
D.Our feelings and emotions come from the most developed area in our brain.
【小題4】. In this article, we can know except _____.
A.it takes four to five times as much blood to feed our brain as to feed our heart.
B.when adult teeth are gone, they cannot grow back.
C.the reason why spinning make us dizzy.
D.how we can grow taller.
【小題5】 What is the main purpose of the selection?
A.To give advice on how to stay healthy.
B.To report the latest discoveries in medical science.
C.To challenge new findings in medical research.
D.To provide information about our body.

Passenger pigeons(旅鴿)once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks(群)so large that they darkened the sky for hours.
It was calculated that when its population reach its highest point, there were more than 3 billion passenger pigeons – a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant birds in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.
Sadly, the abundance of passenger pigeons may have been their undoing. Where the birds were abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.
By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood, which scattered(驅(qū)散)the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline. Soon the great flocks were gone, never to be seen again.
In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons, but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden in September 1, 1914.
【小題1】In the 18th and early 19th centuries, passenger pigeons _______.

A.were the biggest bird in the world 
B.lived mainly in the south of America 
C.did great harm to the natural environment 
D.Were the largest population in the US 
【小題2】The underlined word “undoing” probably refers to the pigeons’ _______.
A.escape B.ruin C.liberation D.evolution 
【小題3】What was the main reason for people to kill passenger pigeons?
A.To seek pleasure. B.To save other birds. 
C.To make money. D.To protect crops. 
【小題4】What can we infer about the law passed in Michigan?
A.It was ignored by the public. B.It was declared too late. 
C.It was unfair. D.It was strict.

In the future your automobile will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!
For each prediction that has come true today, several others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or whether people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.
Robot Helpers

Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other manufacturing environments.
Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.
So why hasn’t it happened? Probably because robots are still too expensive and clumsy. And maybe the idea of robots cooking our dinners and washing our clothes is just too weird. At home we seem to be doing fine without them.
Telephones of Tomorrow
In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet.
Why? The technology worked fine, but it over-looked something obvious: people’s desire for privacy. Would you want to have a video phone conversation with someone after you just step out of the shower? Probably not—it could be embarrassing! Just because a technology available doesn’t always mean people will want to use it.
And finally, how about that crazy prediction of the flying car? It’s not so crazy anymore! But a flying car remains one of the most fascinating technology ideas to capture our imagination. Keep watching the news, or perhaps the sky outside your window, to see what the future will bring.
【小題1】The whole passage is mainly about   .

A.predictions that have come true
B.predictions that haven’t come true
C.why predictions don’t come true easily
D.what technology will bring about
【小題2】The author of this passage won’t believe that   .
A.predictions needn’t consider people’s practical use of technology
B.the future isn’t always easy to guess
C.not all past predictions have come true
D.many of the high-tech things our parents thought we’d be using by now simply never appeared
【小題3】The underlined word “weird” in Para. 5 probably means   .
A.wonderful         B.stupid
C.practical D.strange
【小題4】What does the author think of the flying car?
A.It is too difficult to imagine.
B.It is too crazy an idea.
C.It is likely to be made.
D.It is often reported in the news.
