Archive Gallery : The Best of Bionics(仿生学)

Humans might be the most highly-evolved species on the planet,but most animals possess skills we can
only dream of having. Imagine how much electricity we could save if we could see in the dark the way cats
do. Imagine leaping from tree to tree like a monkey. Giraffes(长颈鹿),which are otherwise calm and good-
natured,sleep only 4.6 hours a day.
We realized a long , long time ago that nature provides the best blueprint(蓝图)for invention. We ' ve
borrowed canals from beavers(河狸)and reflectors from cat's eyes. Although the words"bionics"became
popular only after the l960s,history shows that nature has always provided ideas on solving everyday prob-
lems. Our archives(档案)don't go back to the time of Leonardo da Vinci and his bird-like flying machines,
but we can take you to the late 19th century,where we applied those same principles for building our first
practical airplanes.
To prepare for their flight at Kitty Hawk,the Wright brothers studied the movements of pigeons to fingure
out how they stayed high up when they were heavier than air. Their success inspired scores of successors to
improve on the airplane by studying various aspects of nature.One of Orville Wright's pupils caught and
stuffed seagulls to examine their wingspan.Meanwhile,two French inventors examined spinning sycamore(美
国梧桐)seeds in an effort to apply those same motions , reversed , to a helicopter.
Some examples are more obvious than others.The outside of the airplane designed by the Wright
Drotliers looks like a minimalistic(简单抽象艺术)structure. On the other hand , Barney Connett ' s fish
iubmarine(潜水艇)actually looks like a fish.
Some bio-inspired concepts have yet to be invented.In the l960s,the US Army commissioned several
iniversity professors to conduct research on the motor skills of animals in hope of applying those same abili-
ies to tanks. Tanks that run like horses or jump like grasshoppers(蚂炸)一sounds shocking,doesn't it?
3ut imagine how life would change if we could achieve that.

"Cats","monkeys"and"giraffes"mentioned in Paragraph 1 are examples to illustrate____________.
A:they are highly-evolved species as humans
B:humans can learn animals' skills
C:they are skillful in different ways
D:animals have skills that humans do not possess

考题 Our dream is the song of our soul. Life without one is reduced to a hollow existence. But life with a dream is filled with meaning and purpose.Most of us have a dream, or heart's desire. But the trouble is most of us have the on/off switch of our dream set to OFF. Whenever we say, I can’t, we set the switch to OFF. Whenever we believe we can, we set the switch to ON. Simple, isn't it? Just because I believe I can do something doesn't mean there won’t be any problems. But once I believe I can do it, I will seek solutions for every problem I stumble on. And since it is a law of life that we find what we look for, if I look for solutions, I will find them.Any worthy dream is a dream worthy of accomplishing. Once I realize I can do it, the next step is to make a commitment. As soon as we make a commitment, great power is released. What seemingly were insurmountable hurdles are now reduced to obstacles of laughable insignificance. But we won’t reach this stage until we decide to stop talking and start acting. Unless we commit ourselves, self-doubt will ferment and block our way.Our dreams don’t have to be grand to be great. An aunt of mine sold gloves in a department store for most of her life. Her dream was to be the friendliest and most helpful salesperson around. Year after year, the same customers would return and deliberately seek her out. She brightened everyone's day and touched the lives of thousands. Was her dream any less significant than that of aprominent person? Of course not. We all have the power to follow a dream that will make a difference to us and those we meet.No dream is too small; no dream is too big, so hold on to your dream. Langston Hughes tells why, Hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly.So,what are you waiting for? Follow your dream!(1)According to the author, dreams ___________.A、refer to dreams in our sleepB、refer to dreams in the daytimeC、gives meaning and purpose to our lifeD、enables life to be a hollow existence(2)What are the stages in following a dream?A、Setting the switch of our dream on, making a commitment, and releasing the power.B、Setting the switch of our dream on, committing ourselves, and following the dream.C、Believing we can do it, committing ourselves, and acting.D、Believing we can do it, acting and making a commitment.(3)What does the dream of the author's aunt illustrate?A、To illustrate we should commit ourselves and start acting.B、To illustrate our dreams don’t have to be grand to be great.C、To illustrate her dream was to be the friendliest and most helpful salesperson.D、To illustrate we all have the power to follow a dream.(4)Which of the following statements is NOT true?A、Whether the switch of your dream is ON or OFF is left entirely to yourself.B、If we believe we can do it, there won’t be any problems.C、We will find what we look for.D、The author's aunt's dream was not any less significant than that of a prominent person.(5)The passage mainly tells us that __________.A、a dream gives meaning and purpose to our life.B、if dreams die, life will become meaningless.C、we should follow our dream which will make a difference to us and other people.D、a worthy dream is a dream worthy of accomplishing.

考题 共用题干 第二篇Three Ways to Become More CreativeMost people believe they don't have much imagination.They are wrong. Everyone has imagination,but most of us,once we become adults,forget how to access it. Creativity isn't always connected with great works of art or ideas.People at work and in their free time routinely think of creative ways to solve problems.Maybe you have a goal to achieve,a tricky question to answer or you just want to expand your mind!Here are three techniques to help you.This technique involves taking unrelated ideas and trying to find links between them.First,think about the problem you have to solve or the job you need to do.Then find an image,word,idea or object,for exam- pie,a candle.Write down all the ideas/words associated with candles:light,fire,matches,wax,night,silence, etc.Think of as many as you can?The next stage is to relate the ideas to the job you have to do?So imagine you want to buy a friend an original present,you could buy him tickets to a match or take him out for thenight.Imagine that normal limitations don't exist. You have as much time/space/money,etc.as you want. Think about your goal and the new possibilities.If,for example,your goal is to learn to ski,you can now prac- tice skiing every day of your life(because you have the time and the money).Now adapt this to reality.May- be you can practice skiing every day in December,or every Monday in January.Look at the situation from a different point of view. Good negotiators(谈判者)use this technique in business; and so do writers.Fiction writers often imagine they are the characters in their books.They ask questions: what does this character want?Why can't she get it?What changes must she make to get what she wants? What does she dream about?If your goal involves other people,put yourself" in their shoes".The best fisher- men think like fish!According to the passage,when we become adults_______________.A:most of us are no longer creativeB:we are not as imaginative as childrenC:we can still learn to be more creativeD:we are unwilling to be creative

考题 共用题干 Ecosystem1 The word " ecosystem" is short for ecological(生态的)system. An ecosystem is where living crea- tures expand within a given area.You can say that an ecosystem is the natural environment where biologicalorganisms(生物)such as plants,animals and humans co-exist in this world. So naturally that includes you and mne.Yes,we are all members of an ecosystem!2 There are different kinds of ecosystems depending on the type of suiface or environment. Most are naturally made 5uch as the ocean or lake and the desert or rainforest.Some are man-made or artificial to en- courage co-habitation(共居)between living and non-living things in a monitored environment,such as azoo or garden.3 Plants make up the biggest group of biological creatures within an ecosystem,and that's because they are the natural food producers for everyone.Plants raised in the earth need air and collect sunlight to help them grow.When they grow,the plants and their加its or flowers eventually become a source of food to animals,microorganisms (微生物)and even humans, of course. Food is then converted to energy for the rest of us to function,and this happens in a never-ending cycle until the living creatures die and break up back in the earth.4 Ecosystems are the basis of survival for all living things.We depend on plants and animals for food. In order for us to exist,we need to grow and care about other organisms.We also need tO care for the non一living things within our environment like our air and water so we can continue living as a population.Since plants, animals and humans are all of various species(物种),we all play a role in maintaining the ecosystem.5 To preserve our ecosystems,we should stop using too much energy,which happens汕en we consume more than our share of resources. Humans should not disturb the natural habitat(栖息地)of plants and animals, and should allow them to grow healthily for the cycle to continue.Too many people in a habitat can mean dis- placement(搬迁):imagine being thrown out of your home because there is no more space for everyone. Worse,overpopulation can also ruin the environment and cause destruction of existing plants and animals. Paragraph 3_______A: What Can We Do to Help Protect Ecosystems?B:What Are Different Types of Ecosystems? C:What Is an Ecosystem?D: What Destroys Ecosystems? E:How does an Ecosystem Work?F: Why Are Ecosystems Important?

On the other hand , Barney Connett ' s fishsubmarine(潜水艇)actually looks like a fish.Some bio-inspired concepts have yet to be invented.In the 1960s,the US Army commissioned several university professors to conduct research on the motor skills of animals in hope of applying those same abili- ties to tanks. Tanks that run like horses or jump like grasshoppers(蚂昨)一sounds shocking,doesn't it? But imagine how life would change if we could achieve that. What happened after the Wright brothers' success?A:People carried out a systematic study on pigeons.B:People could fly their airplanes for fun.C:People kept their airplanes at a French gallery.D:People studied more animals and plants to develop the airplane.

An ecosystem is where living crea- tures expand within a given area.You can say that an ecosystem is the natural environment where biologicalorganisms(生物)such as plants,animals and humans co-exist in this world. So naturally that includes you and mne.Yes,we are all members of an ecosystem!2 There are different kinds of ecosystems depending on the type of suiface or environment. Most are naturally made 5uch as the ocean or lake and the desert or rainforest.Some are man-made or artificial to en- courage co-habitation(共居)between living and non-living things in a monitored environment,such as azoo or garden.3 Plants make up the biggest group of biological creatures within an ecosystem,and that's because they are the natural food producers for everyone.Plants raised in the earth need air and collect sunlight to help them grow.When they grow,the plants and their加its or flowers eventually become a source of food to animals,microorganisms (微生物)and even humans, of course. Food is then converted to energy for the rest of us to function,and this happens in a never-ending cycle until the living creatures die and break up back in the earth.4 Ecosystems are the basis of survival for all living things.We depend on plants and animals for food. In order for us to exist,we need to grow and care about other organisms.We also need tO care for the non一living things within our environment like our air and water so we can continue living as a population.Since plants, animals and humans are all of various species(物种),we all play a role in maintaining the ecosystem.5 To preserve our ecosystems,we should stop using too much energy,which happens汕en we consume more than our share of resources. Humans should not disturb the natural habitat(栖息地)of plants and animals, and should allow them to grow healthily for the cycle to continue.Too many people in a habitat can mean dis- placement(搬迁):imagine being thrown out of your home because there is no more space for everyone. Worse,overpopulation can also ruin the environment and cause destruction of existing plants and animals.In an ecosystem,plants,animals and humans live together in________.A:our share of resoureesB:a biological creatureC:a given areaD:the maintenance of the ecosystemE:the source of foodF:various species

考题 问答题Practice 1  No one knows what time itself is. We cannot see it. We cannot touch it. We cannot hear it. We know it only by the way we mark its passing. For all our success in measuring the tiniest parts of time, time remains one of the great mysteries of the universe.  One way of thinking about time is to imagine a world without time. There could be no movement, because time and movement cannot be separated. A world without time could exist only as long as there were no changes. For time and change are linked. When something changes, you know time has passed.

考题 问答题One of the questions coming into focus as we face growing scarcity of resources in the world is how to divide limited resources among countries. In the international development (1) com____, the coronal wisdom has been that the billion people living in poor countries could never expect to (2) r____ the standard of living that most of the people in North America enjoy, simply because the world does not contain enough iron ore, protein, petroleum, and so on. At the same time, we in the United States have continued to pursue super-affluence as though there were no limits (3)____ how much we could consume. We (4) m____ only 6 percent of the world’s people; yet we consume one third of the world’s resources.  As long as the resources we consumed each year came primarily from (5) w____ our own boundaries, this was largely an internal matter. But as our resources come more and more from the outside world, we will no longer be able to think in (6)____ of “our” resources and “their” resources, but only of (7) c____ resources.  As Americans consume such a(n) (8)____(proportion) share of the world’s resources, we have to question whether or not we can continue our pursuit of super-affluence in a world of (9)____(scarce). We are now reaching the point at which we must carefully examine the presumed link between our level of well-being and the level of material goods consumed. If you have only one crust of bread and get another crust of bread, your well-being is greatly enhanced. But if you have a loaf of bread, then an additional crust of bread doesn’t make (10) d____. In the eyes of most of the world today, Americans have their loaf of bread and are asking for still more. The prospect of a scarcity of, and competition in, the world’s resources requires that we re-examine the way in which we relate to the rest of the world.

考题 问答题As holidays go, Thanksgiving is in some ways the most philosophical. Today we try not to take for granted the things we almost always take for granted. We try, if only in that brief pause before the eating begins, to see through the well-worn patterns of our lives to what lies behind them. In other words, we try to understand how very rich we are, whether we feel very rich or not. Today is one of the few times most Americans consciously set desire aside, if only because desire is incompatible with the gratitude—not to mention the abundance-that Thanksgiving summons.
