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 (仿生学) 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(翠鸟). 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!The first paragraph is written to_____.

One day I walked down to get to my car, thinking about what I had to accomplish and scolding myself for being late for work, but surprisingly the car was nowhere to be found.
This was at 8 a.m. in the morning. I made trips to all the towing places and police stations, all the time thinking that it was towed (拖走）by cops (巡警).By around 10 a.m., the cops decided that it was actually stolen. After filing a report with them, I finally got to work thinking how my day was completely messed up.
Later in the day I went to pick up a rental car at Enterprise only to realize that my license was missing, too, along with my car. I told the enterprise guy the whole story and he offered to take me to the closest DMV and get a duplicate (副本) license. 1 was totally shocked.

While many young people may resist getting a "real job" or becoming independent, these are the things that make you happy and give you purpose. Some people underestimate the satisfaction of working, thinking they'll be miserable. The 20-somethings that do work are happier than those who don' t or are underemployed.
If you invest in your career early，you'll have longer to build it up. 70% of wage growth happens in the first 10 years, so you need to get the best job you can get and negotiate your salary. No one can be sure that people who will wait until their 30s to get going are expecting to experience later to catch up with those of their ages.
Many 20-somethings don't know what they want to do, so they hang around the house or in. low-level jobs waiting for the spirit to move them. Not making a choice is a choice. These 20-somethings think they are keeping their options open, but they are actually closing doors. Resumes start to look thin, their peers(同龄人) begin surpassing them and they may get stuck in underemployment.
It will take about 10,000 hours(or about five years)to really master their jobs. If you're wondering why colleagues seem so smart and confident, it's partly because they've been doing it longer. Young people should learn as much as they can in their first jobs and remember it will take some time to really get good.
The 20-something brain is still developing, which is in charge of critical emotion with reason. This, coupled with less on-the-job experience, means 20-somethings are more sensitive to surprise and criticism. They are more likely to take feedback personally. Step back and get some perspective. You're not going to be fired because your boss is angry. Hear the criticism and learn from it.
The brain doesn't fully mature until your mid-20s, particularly the parts that plan for the future and manage emotions. That doesn't mean you should sit around and wait for it to develop. In. fact, what you learn and experience in your 20s becomes hardwired into your brain and this is the best chance you have to change your brain and change how you think and react. What people do in their 20s determines who they'll be as adults. What is the best title of the passage?
| A．How You Spend Your 20s Will Define You. |
| B．The 20-something Brain Remains To Be Developed. |
| C．Young People Need Employment And Experiences. |
| D．Becoming Mature Should Invest In The Career. |
What can we infer from the whole passage?
| A．Not all people resist becoming independent. |
| B．Adult responsibilities make you happier. |
| C．Not making a choice is a better policy |
| D．It takes chances to get good jobs. |
What does the underlined part "coupled with" mean according to the passage?
| A．multiplied by | B．recounted in. |
| C．composed of. | D．combined with. |
What idea does the writer of the passage support?
| A．Take feedback personally anytime and anywhere. |
| B．It is never too late to wait till a choice is made. |
| C．A lesson should be learned from criticism. |
| D．The satisfaction of working is not contented. |
Oscar-winning director Ang Lee' s new epic "Life of Pi" reveals the relationship between a teenage Indian boy and a Bengal tiger. But in reality, the predators(食肉动物)are under increasing threat from humans. Animal rights group PETA is hoping to use the popularity of the film to focus people's attention on the real life of Bengal tigers.
With the rising demand for tiger parts from East Asia, illegal hunting remains a tremendous danger for the remaining cat population. Back in 1947, there were 40,000 tigers in India, but the number is experiencing a sharp decline t0 1,706 despite campaigns to protect the animal.
Rising man-animal conflict is also one of the leading causes of decline in tiger numbers. In one of numerous reported attacks on the endangered big cats, villagers near The Bangladesh-India border, armed with sticks and boat oars, set upon the animal suspected to have attacked a local fisherman and beat it to death earlier this month. So far this year, 58 tiger deaths have been reported in the country.
"The first instinct when a tiger is spotted is to just kill it,"grieved Gurmeet Sapal, a wildlife filmmaker. "The feeling of fear and revenge is so strong that it shuts out any other emotion. What we don' t realize is that the tiger never attacks humans until it is forced to. "'
India has been struggling to stop the tiger's decline in the face of the loss of habitat as well that encourages the animals to leave the forest for food. " The tiger's rapidly exhausted prey base causes the predator to go al! out to get its food. Consequently, livestock and human beings become easy prey, which leads inevitably to conflict," says a wildlife conservationist.
Filmmaker Sapal says it is only normal for people to think of the tiger as a dangerous animal, but its image as a human killer bears some injustice. "Tigers never kill for sport nor store meat. They kill their prey only in case of hunger. "How can PETA take advantage over the hot movie “ Life of Pi ”?
| A．PETA can count on the movie to promote people' s awareness of tiger' s life. |
| B．PETA can make enough money by encourage people to watch the movie. |
| C．The movie demonstrates that humans and tigers can live in harmony. |
| D．The movie offers a wonderful opportunity for movie to act in. |
Why did the villagers beat the tiger to death?
| A．Because it was a human killer and attempted to attack people. |
| B．Because it was suspected to be a threat to local people' s lives. |
| C．Because local people just followed their instinct to kill it. |
| D．Because people wanted to carry out their revenge for it. |
According to the article, when will tigers attack and kill people?
| A．When they are annoyed by people. |
| B．When they have conflict with people. |
| C．When they are driven to act in the movie. |
| D．When they are hungry or attacked. |
What contributes to the facts that livestock and human beings become easy target of tigers?
| A．It is easier for tigers to hunt human beings than other animal for food. |
| B．Tigers are losing their habitat and forced to go out of the woods. |
| C．People hold a strong belief that tigers are a born threat to their lives. |
| D．Tigers can't be treated equally as other animal in the forest |
I dropped out of Reed College after the first 6 months, but then stayed around as a drop-in (旁听生） for another l8 months or so before I really quit. So why did I drop out?
It started before I was born. My biological mother was a young, unmarried college graduate student, and she decided to, put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife. Except that when I popped out they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting list, got a call in the middle of the night asking: "We have an unexpected baby boy; do you want him?" They said: "Of course. " My biological mother later found out that my mother had never graduated from college and that my father had never graduated from high school. She refused to sign the final adoption papers, She only gave in a few months later when my parents promised that would someday go to college.
And 17 years later I did go to college. But I artlessly chose a college that was almost as expensive as Stanford, and ail of my working class parents' savings were being spent on my college tuition. After six months, I couldn't see the value in it. I had no idea what I wanted to do with my life and no idea how college was going to help me figure it out. And here I was spending all of the money my parents had saved their entire life. So I decided to drop out and trust that it would all work out OK. It was pretty scary at the time, but looking back it was one of the best decisions I ever made. The minute I dropped out I could stop taking the required classes that didn't interest me, and begin dropping in on the ones that looked interesting.
It wasn't all romantic. I didn't have a dorm room, so I slept on the floor in friends' rooms, I returned coke bottles for the $ 5 deposits to buy food with, and I would walk the 7 miles across town every Sunday night to get one good meal a week at the Hare Krishna temple. I loved it. And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on.From the passage we know that the author.

London will stage its biggest political funeral in almost half a century on Wednesday when Britain's governing elite join the Queen and global leaders to bid farewell to former Prime Minister Margaret Thatcher, better known as the “ Iron Lady".
In an event comparable to that of Winston Churchill's funeral in 1965, Thatcher's coffin will be carried on a horse-drawn gun carriage through streets lined with admirers from parliament to the city's most famous cathedral.
The bells of London's symbolic Big Ben clock tower will fall silent for the first time since Churchill's funeral and more than 700 men and women from Britain's armed forces will honor a woman who led them to victory in the 1982 Falklands War as foreign politicians from around 170 nations look on.
Surveys have shown that many are unhappy that the estimated l0-million($15 million)pound bill for the funeral is being picked up by the taxpayer, while some left-wing lawmakers say the luxurious funeral is too expensive.
But her admirers, of whom there are many in her party and in southern England, argue that her historical profile deserves such a funeral. She was the country's first and only woman premier, was Britain's longest-serving prime minister of the 20th century, and won three general elections.
More than 2,300 mourners will attend including 11 serving prime ministers from around the world, the British government's entire cabinet, two heads of state and 17 foreign ministers.
But there will be notable absences. Former Soviet leader Mikhail Gorbachev is too ill to attend and Nancy Reagan, the widow of Thatcher's great U·S. ally Ronald Reagan, is also unable to come.
Thatcher struck up a close relationship with Reagan during the Cold War, backed the first President George Bush during the 1991 Gulf War, and was among the first to discover that Gorbachev was a man she could "do business with. ”
Covered in the red, white and blue British flag, Thatcher's coffin lay overnight in a 13th-century church in Britain's parliament, a forum she dominated for years. From the passage we know that Big Ben clock tower will fall silent to.
| A．get repaired for the first time |
| B．honour the passing away of the great woman |
| C．tell the specific time to the public |
| D．welcome the officials from all over the world |
Who that are still alive will be absent from the funeral?
| A．Mikhail Gorbachev and Nancy Reagan. |
| B．Mikhail Gorbachev and Ronald Reagan. |
| C．Nancy Reagan and Ronald Reagan. |
| D．George Bush and Mikhail Gorbachev. |
From the passage we can learn that Margaret Thatcher was.
| A．strong and smart | B．weak and disappointing |
| C．aggressive and warlike | D．stubborn and luxurious |
Which of the following might serve as the best title of the passage?
| A．The legend of Thatcher, the “Iron Lady". |
| B．Why Big Ben falls silent for the first time? |
| C．Who will pay for such a luxurious funeral? |
| D．London will witness its biggest political funeral. |
