US military is attempting to develop a new style “insect robot” to replace the human soldier to go wherever he can’t. The greatest trouble this project has fallen across is how to enable the robot to fly freely like an insect， said an official of the Pentagon(五角大楼).
The Pentagon is seeking for the cooperation with scientists in hope of developing a new technique by which people can control the insect’s flight direction and pass on the information its eyes or other organs catch through the equipment set in its body， the official said.
It is thus designed that a tiny controlling chip will be equipped in an insect’s body when it is in chrysalis(蛹). As the insect grows， the cut made when fixing in the chip will be recovered. The chip will exist in forever. Scientists believe this won’t influence the insect， sound growth or the functions of internal organs.
The terminal target of the project is to set up a global system， in which the insect robots will be stationed in all parts of the world and stick to their posts till a new instruction is received. At that time the military can receive from all over the world clear image information within about 5 meters of the insects and that of a special target within 100 meters.
Years ago， Defense Advanced Research Projects Agency of US DOD(国防部) spent $3,000,000 carrying out a plan for training bees to detect landmines. But， no new progress has so far been made.
“According to the scientists， there is still enormous difficulty in technology in turning it into reality， such as the insects reproduction(繁殖)， their adaptation to the surroundings and temperature and so on. However， this project is really challenging. If successful， it is equal to making countless small drone(无人机)，”said the official of DOD.According to the description of the passage， what is an insect robot like？

Tail Spin
Two dolphins race around in a big pool in the Ocean Park. The smaller dolphin Grace, shown off a few of her tricks, turning around and waving hello to the crowd. The most amazing thing about her, however, is that she’s even swimming at all. She doesn’t have a tail.
Grace lost her tail as a baby when she got caught up in a fish trap.
When the dolphin arrived at the Ocean Park in December 2005, she was fighting for her life. “Is she going to make it?” Her trainer, Abbey Stone, feared the worst. Grace did make it — but her tail didn’t. She ended up losing her flukes and the lower part of her peduncle.
Over the past six years, she has learned to swim without her tail. Dolphins swim by moving their flukes and peduncle up and down. Grace taught herself to move another way—like a fish! She pushed herself forward through the water by moving her peduncles from side to side.
The movement put harmful pressure on Grace’s backbone. So a company offered to create a man-made tail for her. The tail had to be strong enough to stay on Grace as she swam but soft enough that it wouldn’t hurt her.
The first time Grace wore the artificial tail. She soon shook it off and let it sink in the bottom of the pool. Now, she is still learning to use the tail. Some days she wears it for an hour at a time, others not at all. “The tail isn’t necessary for her to feel comfortable,” says Stone, “but it helps to keep that range of motion(动作) and build muscles(肌肉).”
Now, the dolphin is about to get an even happier ending. This month, Grace will star in Dolphin Tale, a film that focus on her rescue and recovery. Her progress has inspired more than just a new movie. Many people travel from near and far to meet her. Seeing Grace swim with her man-made tail gives people so much courage.When Grace first arrived at the Ocean Park, her trainer worried about her .
| A．physical build | B．potential ability |
| C．chance of survival | D．adaptation to the surroundings. |
A man-made tail is created for Grace to .
| A．let her recover faster | B．make her comfortable |
| C．adjust her way of swimming | D．help her perform better tricks |
The story of Grace inspires people to .
| A．stick to their dreams | B．treat animals friendly |
| C．treasure what they have | D．face difficulties bravely |
The idea for the book Harry Potter and the Philosopher's Stone came to Joanne Kathleen Rowling in 1990. It took her seven years to finish writing it. During those seven years she had a number of jobs, including one job as an English teacher in Portugal.
Rowling sent the book to four publishers before one of them bought it. She was very happy to sell her book because it was her life's dream to be a published writer. Before she sold her book, Rowling was living in a small apartment with her daughter and was so poor that she could not afford heat in the winter.
Harry Potter became very successful with children and adults in England. The book also really took off in the United States. After her second and third books were published, the three Harry Potter books filled the top three places on many newspapers' lists of best-sellers. Then the books were made into popular movies. Without question, Rowling's life had completely changed, in just three years.
Harry Potter books have now sold more than 30 million books around the world and have been translated into more than thirty-five languages. In 1997, Rowling was earning ￡70 (about US$110) a week. By the end of 2001, she had earned over ￡150 million ($250 million), making her one of the most successful female writers of all time. This reading is about _________.

“I’m a little worried about my future．”said Dustin Hoffman in The Graduate．He should be so lucky．All he had to worry about was whether to have an affair with Mrs. Robinson．In the sixties，that was the total sum of post-graduation anxiety．
Hoffman’s modem peers are not so fortunate．The Mrs. Robinsons aren’t sitting around at home any more．They are out in the workplace，doing the high-powered jobs the graduates want，but cannot get．For those fresh out of university，desperate for work but unable to get it，there is a big imbalance between supply and demand．And there is no narrowing of the gap in sight．
Parents feel as badly let down as the young people themselves．Middle-class families see their graduate offspring on the dole (救济金) queue and wonder why they bothered paying school fees．Working-class families feel an even keener sense of disappointment．For many such families，getting a child into university was the fulfillment of a lifelong dream．It was proof that they were living in a dynamic，economically successful country．That dream does not seem so rosy now．Graduate unemployment is not，ultimately，a political problem．Job-creation for graduates is very low down in the government’s schedule．If David Cameron’s Conservatives (保守党) had a brilliant idea for guaranteeing every graduate a well-paid job，they would have presented it by now．It is a social problem，though a more deep-seated social problem than people perhaps realize．The author begins with the lines from The Graduate in order to __________ ．
| A．support the fact that more women are working now |
| B．show that few graduates started working right after graduation |
| C．demonstrate that there were much fewer graduates than now |
| D．emphasize the sharp contrast between now and then |
Regarding job opportunities for young graduates，the author sounds __________ ．
| A．pessimistic | B．hopeful | C．unconcerned | D．content |

Redwood trees are the tallest plants on the earth，reaching heights of up to 100 meters．They are also known for their longevity，typically 500 to 1000 years，but sometimes more than 2000 years．A hundred million years ago，in the age of dinosaurs，redwoods were common in the forests of a much more moist and tropical North America．As the climate became drier and colder，they declined to a narrow strip along the Pacific coast of Northern Califomia．
The trunk of redwood trees is very strong and usually forms a single straight column．It is covered with a soft bark．This bark can be pretty thick，well over two feet in the more mature trees．It gives the older trees a certain kind of protection from insects，but the main benefit is that it keeps the center of the tree harmless from moderate forest fires because of its thickness．This fire resistant quality explains why the giant redwood grows to live that long．While most other types of trees are destroyed by forest fires，the giant redwood actually prospers because of them．
Moderate fires will clear the ground of competing plant life，and the rising heat dries and opens the ripe fruit of the redwood，releasing many thousands of seeds onto the ground below．
New trees are often produced from shoots，little baby trees，which form at the base of the trunk．These shoots grow slowly，fed by the root system of the “mother’’ tree．When the main tree dies，the shoots are then free to grow as full trees，forming a “fairy ring” of trees around the original tree．These trees，in turn，may give rise to more shoots，and the cycle continues．Why were redwood trees easier to find in the forests of North America millions of years ago?
| A．The trees were taller and stronger． |
| B．The soil was softer for seeds to develop． |
| C．The climate there was warmer and wetter． |
| D．The temperature was lower along the Pacific coast． |
Which of the following is a function of the tree bark as mentioned in the passage?
| A．It allows redwood trees to bear seeds． |
| B．It prevents redwood trees from attack by insects． |
| C．It helps redwood trees absorb water in the air． |
| D．It makes redwood trees more beautiful and appealing． |
Why do redwood trees grow to live that long according to the passage?
| A．They have heavy and straight tree trunks． |
| B．They are properly watered and catered to． |
| C．They are more resistant to fire damage than other trees． |
| D．They produce many young trees to maintain their life cycle． |
How does a “fairy ring’’ form according to the passage?
| A．By killing an old tree． | B．By connecting root systems． |
| C．By inserting holes into old trees． | D．By surrounding a mature tree． |
Yousuf Karsh，the Canadian portrait artist who photographed many of the most influential figures of the 20th century，died in a Boston hospital on July l3 th，2002．He was 93．
Working from a studio in Ottawa，Karsh produced famous portraits of such subjects as Winston Churchill，John F．Kennedy，Ernest Hemingway and Albert Einstein．Actually he has become almost as famous as his legendary subjects．In the latest edition of Who’s Who，which listed the most notable people of the last century，Karsh was the only Canadian of the 100 famous people listed——51 0f whom Karsh had photographed．
As a master portraitist，often working in black and white．Karsh was famous for talking to his subjects as he was getting the shot’s composition just right，asking them questions and putting them at ease．In preparation，he read as much as he could about the sitters，but avoided having the idea beforehand of how he would photograph them．He sought, as he wrote in Karsh Portfolio in 1967，to capture the “essential element which has made them great，” explaining，“All I know is that within every mall a secret is hidden，and as a photographer, it is my task to reveal it if I can．”
Karsh was born in America in 1908，and his uncle，George Nakash，brought him to John Garo，all outstanding photographer，to teach him in 1928．Four years later，Karsh set up his own studio in Ottawa．
In December of 1941，his memorable portrait of Winston Churchill brought Karsh into international fame．Canada’s Prime Minister Mackenzie King arranged for him to photograph Churchill following Churchill’s speech in the House of Commons．Not told，Churchill lit up a cigar, “Why was I not told of this?’’ Karsh asked him to remove the cigar and，when he didn’t，stepped forward and gently removed it with the comment，“Forgive me，Sir．”Churchill glowered (怒目而视) as the shot was taken，then permitted Karsh to take still another,；jokingly commenting，“You can even make a roaring lion stand still to be photographed．” The Churchill portrait has since appeared in publications all over the world．
Karsh traveled to London in 1943 with his portable studio —— an 8-by-10 view camera and many studio lamps to photograph such notables as George Bernard Shaw and the royal family．All these portraits fully illustrate Karsh’s ability．What did Karsh seek to do most in working?
| A．Capture the essence and greatness of the character． |
| B．Present the true and vivid expression of the subject． |
| C．Make the photograph more colorful and expressive． |
| D．Reveal the idea he has got in preparing for the shot． |
