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.
Which of the following can be found in the archive gallery?
A:History books.
B:The Wright brothers' sculpture.
C:First practical airplanes built in the late 19th century.
D:Leonardo da Vinci's bird一like flying machines.

I'll Be Bach
Composer David Cope is the inventor of a computer program that writes original works of clas-sical music .It took Cope 30 years to develop the software.Now most people can't_____(51) the difference between music by the famous German composer J. S.Bach(1685-1750)and the Bach-like compositions from Cope's computer.
It all started in 1980 in the United States,when Cope was trying to write an opera. He was having____(52)thinking of new melodies,so he wrote a computer program to create the melodies.At first this music was not_____(53)to listen to. What did Cope do?He began to rethink how human beings compose music .He realized that composers,brains_____(54)like big databases. First,they take in all the music that they have ever heard.Then they take
_____（55)the music that they dislike.Finally,they make new music from what is_______(56).According to Cope,only the great composers are able to create the database accurately, remember it,and form new musical patterns from it.
Cope built a_____(57)database of existing music.He began with hundreds of works by Bach .The software analyzed the data:it______(58)it down into smaller pieces and looked for patterns. It then combined the______(59)into new patterns. Before long,the program could compose short Bach-like works.They weren't good,but it was a start.
Cope knew he had more work to do—he had a whole opera to write.He continued to improve the software. Soon it could______(60)more complex music.He also added many other com-posers,including his own work to the database.
A few years later,Cope's computer program,called“Emmy”,was ready to help him with his opera. The______(61)required a lot of collaboration between the composer and Emmy. Cope listened to the computer's musical ideas and used the______(62)that he liked.With Emmy,the opera took only two weeks to finish.It was called Cradle Falling,and it was a great _____(63)!Cope received some of the best reviews of his career,but no one knew exactly _____(64)he had composed the work.

Learning Disabilities
Learning disabilities are very common.They affect perhaps 1 0 percent of all children.Four times as many boys as girls have learning disabilities.
Since about 1970,new research has helped brain scientists understand these problems better.Scientists now know there are many different kinds of learning disabilities and that they are caused by many different things.There is no longer any question that all learning disabilities result from differences in the way the brain is organized.
You cannot look at a child and tell if he or she has a learning disability.There is no outward sign of the disorder.So some researchers began looking at the brain itself to learn what might be wrong.
In one study,researchers examined the brain of a learning-disabled person who had died in an accident. They found two unusual things.One involved cells in the left side of the brain,which control language.These cells normally are white.In the learning disabled person,however,these cells were gray.The researchers also found that many of the nerve cells were not in a line the way they should have been.The nerve cells were mixed together.
The study was carried out under the guidance of Norman Geschwind,an early expert on learning disabilities, Doctor Geschwind proposed that learning disabilities resulted mainly from problems in the left side of the brain. He believed this side of the brain failed to develop normally.Probably,he said,nerve cells there did not connect as they should.So the brain was like an electrical device in which the wires were crossed.
Other researchers did not examine brain tissue.Instead,they measured the brain's electrical activity and made a map of the electrical signals.
Frank Dully experimented with this technique at Children's Hospital Medical Center in Boston.Doctor Dully found large differences in the brain activity of normal children and those with reading problems.The differences appeared throughout the brain.Doctor Dully said his research is evidence that disabilities involve damage to a wide area of the brain,not just the left side.
Scientists found that the brain cells of a learning-disabled person differ from those of a normal person in______.
A:structure and function
B:color and function
C:size and arrangement
D:color and arrangement
