What do butterfly wings have to do with computer screens? What do birds have to do with high speed trains?
These may sound like strange things to put together. But scientists, inventors, and designers are doing just that. They are learning from nature to create new technology.
The word biomimicry (仿生學) combines two words: biology and mimicry. So people using biomimicry try to use examples in nature to design new technology.
Biomimicry is not a new idea. People have been studying nature for hundreds of years. Leonardo DaVinci used birds as models to invent his flying machine. And when the Wright Brothers made the first successful airplane, they also studied birds. In 998, Janine Benyus, a natural science writer and teacher, wrote a book about biomimicry. To develop her interest in the subject, Janine Benyus started the Biomimicry Institute.
The Biomimicry Institute is a non-profit organization. It brings together scientists, designers, inventors and many other people. It offers classes to teach people biomimicry. It provides money for people to research and test new technologies. And it wants all people, from children to adults, to think about new ways to learn from nature.
People involved with the Biomimicry Institute believe that biomimicry can help solve many of the world’s problems. Often, new technologies can harm nature, but this is not true for biomimicry. Let’s look at some examples.
Butterflies have colorful wings because light shines off them in a special way. Scientists want to copy these same ways to make light shine off computers. They hope this will make for more colorful screens.
Another example of biomimicry is the bullet train. It travels at speeds of over 250 kilometers per hour! But it had a problem: it made too much noise!
Through the observation of birds, scientists thought about a kind of bird, the kingfisher(翠鳥). The kingfisher can dive into water without making any noise because of the shape of its beak(喙). Researchers thought that if they could design the front of the train like this beak, the train would be quieter. Well, it worked!

Air is an odorless (無氣味的), invisible (看不見的) gas that surrounds the earth. It is everywhere on the planet. An “empty” drinking glass and an “empty” room, to give two examples, are not really empty. Each is filled with air. When the glass is filled with water, the water pushes the air out of the glass.
Air, as a gas, has no definite (明確的) shape, but, because it is matter, it takes up space. It is easy to prove that air is something that takes up space. Stuff a dry handkerchief into the bottom（底部） of a glass so that it will not fall out when the glass is turned upside-down. Push the upside-down glass; hold it straight into a jar of water till the glass is completely covered. When the glass is taken out of water, the handkerchief will be dry. The air inside the glass takes up space and keeps the water from coming in.
小題1:What does the underlined word “Stuff” (in Paragraph 2) mean?

A．Press tightly.	B．Take out.
C．Put down.	D．Turn fully.

小題2:The writer tells us that _______.

A．the experiment is done in the laboratory

B．the experiment is done outside the room

C．the experiment is easily done

D．the experiment is carried out indoors

小題3:Which of the following pictures gives us the correct result?
( W—water; A—air; H—handkerchief )

Trying to make a big decision while you’re also preparing for a scary presentation? You might want to hold off on that. Feeling stressed changes how people weigh risk and reward. However, an article published in Current Directions in Psychological Science, a journal of the Association for Psychological Science, suggests stressed people pay more attention to the positive sides of a possible outcome.
It’s a bit surprising that stress makes people focus on the way things could go right, says Mara Mather of the University of Southern California. She co-wrote the review paper with Nichole R.Lighthall. “This is sort of not what people would think, ” Mather says. “Stress is usually associated with negative experiences, so you’d think, maybe I’m going to be more focused on the negative outcomes.”
But researchers have found that when people are under stress, they start paying more attention to positive information and discounting negative information. “Stress seems to help people learn from positive feedback and impairs（削弱）their learning from negative feedback, ” Mather says.
When people under stress are making a difficult decision, they may pay more attention to the good sides of the alternatives they’re considering and less to the problems. So someone who’s deciding whether to take a new job and is feeling stressed by the decision might focus on the increase in salary more than the longer commute（上下班往返）.
The increased focus on the positives also helps explain why stress plays a role in addictions. People under stress have a harder time controlling their urges. “The compulsion to get that reward comes stronger and they’re less able to resist it,” Mather says. A person who’s under stress might think only about the good feelings they’ll get from a drug, while the downsides shrink into the distance.
Stress also increases the differences in how men and women think about risk. When men are under stress, they become even more willing to take risks; when women are stressed, they get more conservative(保守的). Previous research backs this up — men usually react to difficulties while trying to fight them or escape them; women try to find friends and improve their relationships.
小題1:By saying “You might want to hold off on that” in the first paragraph, the writer suggests that .

A．you might want to delay making your big decision

B．you should save the presentation for later

C．you should avoid taking risks

D．you might benefit from the stress

小題2:From the article, we can conclude that stress .

A．often leads people to take more risks

B．often leads people to make balanced decisions

C．makes people think more of negative results

D．makes people ignore the negative side of problems

小題3:Which of the following is TRUE according to the article?

A．Stress is helpful in getting rid of addictions.

B．People who are addicted to drugs are easily stressed.

C．When women are stressed, they do not tend to take risks.

D．When men are stressed, they are more likely to develop an addiction.

小題4:What is the central theme of the article?

A．Stress can affect decision-making.

B．Stress increases our desire to get rewards.

C．We should think more about the upside of problems.

D．There is a link between stress and negative experiences.

Certain animals know without analysis the difference between a number of objects and a smaller number. In his book The Natural History of Selbourne (1786), the naturalist Gilbert White tells how he surreptitiously removed one egg a day from a kind of bird Plover’s nest, and how the mother laid another egg each day to make up for the missing one. He notes that other kinds of birds ignore the loss of a single egg, but if more than one egg has been removed, they will give up their nests. It has also been noted that a certain type of bees always provides five—never four, never six—caterpillars (毛蟲) for each of their eggs so that their young have something to eat when the eggs have hatched out. Research has also shown that both mice and pigeons can be taught to distinguish between odd (奇數) and even (偶數) numbers of food pieces.
These have led some people to think that creatures can actually count. They also point to dogs that have been taught to respond to questions about numbers with the correct number of barks.
Animals respond to quantities only when they are connected to survive as in the case of the eggs, or survive as in the case of food. They can “count” only when the objects are present and only when the numbers involved are small—no more than seven or eight. In lab experiments, animals which are trained to count one kind of objects were unable to count any other type. What interests them are the objects, not the numbers. Animals’ achievements simply are not equal to evidence of counting. They only show the results of clever, careful training.
小題1:The author refers to Gilbert’s book in paragraph 1 in order to_______.

A．support the idea that animals can count

B．show attitudes have changed since 1786

C．prove that some animals are aware of quantities

D．indicate that more research is needed in this field

小題2:The author mentions all of the following are aware of quantities in some way EXCEPT _______.

A．caterpillars	B．bees
C．mice	D．plovers

小題3:The underlined word “surreptitiously” probably means _______.

A．quickly	B．carefully
C．occasionally	D．secretly

小題4:Where does this text probably come from?

A．A news report.	B．A science fiction.
C．A park guide.	D．A biology magazine.

Most recently, it’s very common in students who need a parent present for job interviews.
Naturally, it’s easy to blame the students in these situations, but the bigger problem is us. We—as parents—are so eager to protect our kids that we fail to realize that this in itself is harming them. As the mother of two young sons, I have to remind myself all the time that the biggest responsibility I have as a parent is to help them develop the skills needed to live in, to live without me. So, I’ll let them fail.
I’ll let them fail because as long as they are safe and warm inside their comfort zones, they will never grow. And failure—along with loss, heartbreak, disappointment, etc.—will be part of growth for them. Call me the anti-tiger mom, but leaving them alone is my way of helping them become equipped to fit in this world as we know it today. From terrorism (恐怖主義) and seemingly endless natural disasters, to our national debt and beyond, if we expect the next generation to stand up to the very real problems of our time, we need to stop feeding them and start teaching them how to fish.
My children are faced with hard situations in their own life almost each day, but they try to negotiate (協商) everything now. It’s a small price to help them learn a skill they’ll use for the rest of their lives, including when I don’t come with them on job interviews.
小題1:Why do parents go along with their kids on job interviews?

A．Because they want to protect their kids from difficulties.

B．Because they think they can protect them from being hurt.

C．Because their kids are too shy to attend interviews.

D．Because their kids strongly request them to do so.

小題2:According to the author, what is helpful to kids’ development?

A．Protecting them.	B．Keeping them safe.
C．Leaving them alone.	D．Blaming them.

小題3:The author believes experiencing failure in life can make kids ___________.

A．become healthier than other kids

B．grow in this challenging world

C．develop all social skills

D．escape from natural disasters

小題4:If the writer’s boy goes to a job interview, she probably will ___________.

A．go with him to protect her kid from difficulty

B．stay home but give him directions over telephone

C．wait outside and talk with other parents

D．let him go to the interview by himself

小題5:Which of the following might be the best title of the text?

A．Never help your kids	B．Let your kids fail
C．Go to the interview with your kids	D．Live without parents

Few of us act alone in the real world. Most things are done with the help or ideas of other people. Group projects are great practice for high school, college, and real life, when you will probably have a job that requires working with others. Right now, group projects can be fun and they often allow you to do a bigger, more interesting project than you could alone. With group work, you can actually learn more in less time.
Group projects also give you a chance to get to know kids you might not otherwise know or talk with. Group projects are also a great way to practice skills you’re not so sure of. For example: working on a deadline, staying organized, or being patient. And if you’re a little nervous talking in front of a group, a joint project can help you become more comfortable with it. Maybe your group will pick you to tell the whole class about your project. If so, you’ll know your whole group is rooting for you!
One of the most important things about group work is talking and meeting together. It’s a good idea to continually check with everybody on their progress to see if anyone needs help. You might think the first step is to figure out who will do what, but actually it’s getting to know another a little. Take a few minutes to chat. Even if you know each other well, it can help to take a minute to think about your skills and share your strengths and weaknesses. The second step is to go over ground rules from your teacher and any that you want to create together as a group.
小題1:Group projects can give you a chance to do the following EXCEPT ________.

A．get to know more friends	B．learn more than you do alone
C．work in an organized way	D．get rid of shyness forever

小題2:The underlined phrase “root for” in the second paragraph means _______.

A．like

B．support

C．offer

D．prevent

小題3:What’s the purpose in checking others’ progress?

A．To learn what they will do next.

B．To find good topics to talk with them about.

C．To help them when they need help.

D．To make sure that their work is finished on time.

小題4: According to the passage, we can infer that _______.

A．group members should be your close friends

B．talking with group members should be the first step of group work

C．knowing persons is more important than your projects

D．rules from teachers are more important than working among group members

In Wiltshire, England, volunteers are being sought to visit a nature protection area to count the butterflies living there and on surrounding fields. The project is promoted by all environmental protection organization, which has contributed to improving the living environment for wild animals. Recently, the organization has issued an appeal to help it observe environmental changes based on the record of butterflies and protect the environment.
In the area, the local people have planted many special flowers with the help of the organization, aiming to see whether these flowers will interest the rare and beautiful butterflies. The project officer Sarah Marshall says,“It will be a suitable habitat (棲息地) for butterflies. They are great‘indicator species’ as they are easily affected by climate changes so they make a brilliant early-warning system for the environment.” She also points out that volunteers are needed to record the number or species of butterflies, and based on the change happening to the butterflies, the hidden environmental problems in the area can be found out in time.
The organization is seeking volunteers to help monitor butterflies from April through to September. They will walk a fixed route and record the different butterflies they encounter along the way. Each visit should take no more than two hours, and each volunteer is expected to visit once a month to count the wildlife. “Staff will provide back up, so if the weather is poor on the day you are to visit (butterflies don’t like to fly in the rain, wind or if it’s too cloudy) we can have someone else do your job,” Sarah points out.
No previous experience is necessary as training and support will be provided, but a keen interest is essential. If you are interested please contact Sarah on (01380) 725670, ext 278, email—sarahm @ wiltshirewildlife. org.
