E The mystery of how a pigeon can always find its way back home has finally been solved. Scientists believe that pigeons have a spatial map that allows them to fly in an unfamiliar area and know exactly where they are going. The finding replaces the current theory that pigeons compare their location with that of the home loft and then reduce the difference between the two to find their way home. Nicole Blaser, a student in biology showed the theory that pigeons have a spatial understanding and knowledge of their position in space relative to their home loft. This theory imagines a type of map in their brain. Up until now, there has not been any clear evidence to support this. For their experiments, the researchers trained the pigeons not to get food. “We fed the pigeons in a second loft thirty kilometers away, from where they each had to fly back to their home loft, said Blaser. The scientists then brought the pigeons to a third place unknown to the pigeons in a completely unfamiliar area. Natural obstacles appeared between the release site and the two lofts. One group of the pigeons was allowed to eat before flying home. The other group was kept hungry. As we expected, the satiated pigeons flew directly to the home loft. The hungry pigeons did differently, setting off on course for the food loft from the very beginning and flying directly to that aim. They also flew around obstacles and then immediately changed again to their former course. Based on this evidence, Blaser believes that pigeons can determine their position and their direction of flight relative to the aim and can choose between several places. Blaser concludes that pigeons have a type of cognitive map in their heads and have cognitive capabilities. “Pigeons use their heads to fly, she said. 61. The underlined word “satiated in Para. 4 means the pigeons are . A. angry B. hungry C. interesting D. full 62. The natural obstacles in the experiment are meant to . A. test pigeons’ sense of direction B. show the direction of the home loft C. attract pigeons to their own direction D. separate the home loft and the release loft 63. Which of the following is TRUE about the hungry pigeons in the experiment? A. They flew faster. B. They didn’t pass the obstacles. C. They found directions on their own. D. They had a worse sense of direction. 64. What conclusion does Blaser draw? A. Pigeons can find directions using their mind. B. Pigeons are good at finding directions in unfamiliar places. C. Pigeons can remember directions better than human beings. D. Pigeons find directions by comparing many different places. 65. Where does this text probably come from? A. Science fiction. B. A book review. C. An advertisement. D. A science report. 查看更多

“You do not need to be a rocket scientist.” Americans hear these words often.

People say them in schools, offices and factories. Broadcasters on radio and television use them.

How did the expression begin? No one seems to know it. 66 “It grew,” he says, “because rocket scientists probably are the most intelligent people around.”

Not everyone would agree. Some people might be considered more intelligent than rocket scientists. For example, a person who speaks and reads fifteen languages, or a medical doctor who operates on the brain. Still, many people would agree that there is something special about scientists who build rockets. 67

Moving pictures from before World War II showed a man named Buck Rogers landing on the planet Mars. He was a hero who could withdraw any enemy from outer space. The rocket scientist is a different kind of hero. 68

Rocket scientists, however, can have problems just like everyone else. A Washington rocket scientist tells about a launch that was postponed many, many times. Finally, everything seemed right. Mechanical failures had been repaired. The weather was good. The scientists had planned that part of the rocket would fall into the ocean after the launch. All ships and boats within many kilometers of the danger area had been warned. But in the last few seconds a small boat entered the area. 69

70 One scientist said, "As a child I loved to build rockets. Now I am grown. I still love to build rockets. And now I get paid for it."

A.he or she makes space travel possible.

B.It’s dangerous for rocket scientists to build rockets.

C.Maybe it has something to do with the mystery of space travel.

D.When the work goes well, most rocket scientists enjoy their jobs.

E. Have you ever heard of the space travel?

F. But an official of the American space agency, NASA, says the expression just grew.

G. Once again, the launch was put off.

    Not even Dan Brown and his Da Vinci code—breakers(密码破译者)dared deal with the mystery of Mona Lisa,s smile.But Nicu Sebe,a computer expert the University of Amsterdam,the Netherlands,did.He used’emotion recognition’software to process the famous painting and found Mona Lisa happy(83 per cent)and slightly disgusted(厌烦的)(9 per cent).

    Faces show emotions. Psychology,computer science,and engineering researchers are joining forces to teach machines to read expressions.If they succeed,your computer may one day“read”your mood.Machines equipped with emotional skills could also be used in teaching,gaming,mind-reading,etc.

    “Mind Reader”,a system developed by Rosalind Picard at MIT(the Massachusetts Institute of Technology in the US, uses input from a video camera to do real—time analysis of facial expressions. It reports on whether you seem interested or agreeable or if you’re confused.The system can help people recognize others’emotions.Picard says this means we could teach a machine to be as sensitive as a human.In fact,a machine can be even smarter than people since it can tell if a person is lying or just “performing”by analyzing one’s facial movements.

      Jeffrey Cohn,a psychologist at the University of Pittsburgh,uses the Facial Action Coding System to recognize human emotions.The system sorts more than 40 action units(AUs)of the face to tell people’s real emotions.He studied a videotape of a criminal who said to be sad about the murder of several family members and tried to pin the blame on someone else.But Cohn saw no real sadness in the woman’s face.

      Sadness is a group of AUs that is difficult to do at the same time.You have to pull down the woman’s of your lips while bringing your eyebrows together and raising them.What the woman did was raise her cheeks to make a lip cud(撇嘴)。Her brows stayed smooth.

72.The best title of this passage is“            ”.

      A.The emotion on your face                      B.Look at your face

      C.Your face tells a story                          D.Telling a lie

73.The missing sentence“This means,even though your mouth lice,your face doesn’t,and the machine will know it all. ”should be put at the end of              .

      A.Paragraph 2                         B.Paragraph 3   

    C.Paragraph 4                          D.Paragraph 5

74.How many facial emotion analyses are mentioned in this passage?

      A.Four.                B.Three.               C.Two.          D.One

75.The underlined word“it”refers to——.

      A.MIT                                  B.the video camera

    C.one’s face emotion             D.the real—time analysis

 (09·江西E篇)

New archaeological discovers suggest that trade between Europe and Asia along the Silk Road probably began in some form many countries earlier than once thought. The findings, coupled with a widening range of scientific and historical research could add a fascinating new page to the epic of the Silk Road.

The farest and most surprising discovery is pieces of silk found in the hair of and Egyptian mummy from about 1000 BC, long before regular traffic on the Silk Road and at least one thousand years before silk was previously thought to be used in Egypt. Other research may extend human activity along this route back even further, perhaps a million years to the migration of human ancestors into eastern Asia.

The official origin of East-West commerce along the road is usually placed in the late 2nd century BC which was the agent of the Chinese Emperor Wu-di returned from a dangerous secret mission(使命)across the desert into the remote high country of Central Asia. The agent, Zhang Qian, travelled as far as Afghanistan back knowledge of even more distant lands such as Persia, Syria and a place known as Lijion,. Histerents have called this one of the most important journeys in ancient times. His journey opened the way for what have been thought to be the first indirect contacts between the ancient world’s two superpowers, China and Rome. Chinese silk, first traded to central Asian tribes for war horses and to the Parthians of old Pet la lu exchange for acrobats and ostrich eggs, was soon finding its way through a network of merchants to the luxury markets in Rome.

But the new discoveries show that Chinese silk was apparently present in the West long before the Han emperor started organized trade over the Silk Road. The research could change thinking about the early history of world trade and provide insights into the mystery of just how and when Europe and the Mediterranean lands first became aware of the glorious culture at the other end of Eurasia.

72. The word “coupled” in the first paragraph could best be replaced by         .

A. produced       B. contributed      C. doubled        D. combined

73. The silk thread found in the hair of an Egyptian mummy suggests that          .

A. Egyptians had probably travelled to China to buy silk

B. trade along the Silk Road began earlier than once thought

C. historical research often achieves fascinating results

D. new light can now be thrown on ancient trading practices

74. Until recently most historians believed that trade along the Silk Road        .

A. originated in the 2nd century BC

B. extended human migration into eastern Asia

C. began a million years ago

D. primarily benefited the Egyptians

75. Historians have always considered Zhang Qian’s mission important because they believe            .

A. be brought back knowledge of Rome to the emperor

B. be discovered the Silk Road

C. be helped establish East-West trade

D. be travelled as far as Afghanistan
