Scientists from the Max Plank Institute for Biological Cybernetics in Tubingen, Germany, have presented the first experimental evidence that people do end up walking in circles if lost in unfamiliar areas.The study, published in the journal Current Biology, examined the tracks of people who walked for several hours in the Sahara desert in Tunisia and in the Bienwald forest in Germany.Researchers Jan Souman and Marc Ernst said the scientists used the global positioning system (GPS) to record these paths.The results showed that the walkers were only able to keep a straight line when the sun or moon was visible.As soon as the sun disappeared behind some clouds, people started to walk in circles without even noticing it.
Souman said one explanation offered in the past for people walking in circles was that most people have one leg longer or stronger than the other, which would produce a systematic bias(偏差) in one direction.To test this.the researchers asked people to walk straight while blindfolded which removed the effects of vision.They found that these circles were rarely in a systematic direction, with the same person sometimes switching to the left and sometimes to the right.
"Most of the participants in the study walked in circles, sometimes in extremely small ones.Walking in circles is therefore not caused by differences in leg length or strength, but more likely the result of increasing uncertainty about where straight ahead is," said Souman, "Small random errors (随机性误差) in the various sensory signals that provide information about walking direction add up over time, making what a person perceives to be straight ahead drift away from the true straight ahead direction."
72.The underlined word "this" in Paragraph 2 refers to _____.
A.the effects of vision             B.a systematic bias
C.the leg length differences         D.one explanation offered in the past
73.What is the probable reason for people"s walking in circles?
A.The invisible sun or moon.
B.The increasing uncertainty about directions.
C.Differences in leg length or strength.
D.Wrong signals providing information about areas.
74.Why are the subjects required to be blindfolded?
A.To encourage them to walk straight.    B.To stop them from seeing each other.
C.To dismiss the effects of vision.D.To keep the test a top secret.
75.Which of the following statements is true?
A.People walk straight in the day.
B.The farther people walk, the greater the direction bias grows.
C.People walk only in large circles.
D.Researchers use the global positioning system to record their tracks.

Doing Favours Can Be Dangerous
I found out one time that doing a favour for someone could get you into a lot of trouble.I was in the eighth grade at the time, and we were having a final test.During the test, the girl sitting next to me whispered something, but I didn’t understand.So I leaned over her way and found out that she was trying to ask me if I had an extra pen.She showed me that hers was out of ink and would not write.I happened to have an extra one, so I took it out of my pocket and put it on her desk.
Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed.As soon as we were alone she began to talk to me about what it meant to grow up; she mentioned how important it was to stand on your own feet and be responsible for your own acts.For a long time, she talked about honesty and emphasized the fact that when people do something dishonest, they are really cheating themselves.She made me promise that I would think seriously about all the things she had said, and then she told me I could leave.I walked out of the room wondering why she had chosen to talk to me about all those things.
Later on, I found out that she thought I had cheated on the test.When she saw me lean over to talk to the girl next to me, it looked as though I was copying answers from the girl’s test paper.I tried to explain about the pen, but all she could say was it seemed awfully strange to her that I hadn’t mentioned anything about the pen the day she talked to me right after the test.Even though I tried to explain that I was just doing the girl a favour by letting her use my pen, I am sure she continued to believe that I had cheated on the test.

Liz Murray, a 22-year-old American girl, has been writing a real-life story of willpower and determination.Liz grew up in the shadow of two drug-addicted parents.There was never enough food or warm clothes in the house.Liz was the only member of the family who had a job.Her mother had AIDS and died when Liz was just 15 years old.The effect of that loss became a turning point in her life.Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it.
Liz went back to school.She threw herself into her studies, never telling her teachers that she was homeless.At night, she lived on the streets.“What drove me to live on had something to do with understanding, by understanding that there was a whole other way of being.I had only experienced a small part of the society,” she wrote in her book Breaking Night.
She admitted that she used envy to drive herself on.She used the benefits that come easily to others, such as a safe living environment, to encourage herself that “next to nothing could hold me down”.She finished high school in just two years and won a full scholarship to study at Harvard University.But Liz decided to leave her top university for a couple of months earlier this year in order to take care of her father, who has also developed AIDS.“I love my parents so much.They are drug addicts.But I never forget that they love me all the time.”

(7)------中偏难题
People generally use spices (香料) every day when preparing meals.Most of these spices are readily available in local supermarkets.However, in the 15th and 16th centuries, spices were as valuable as gold or diamonds.Spices are small plants or parts of plants, such as ginger, pepper, vanilla, and cinnamon, which are used to add flavor to our food. 1   Such a use for spices actually goes all the way back to Roman times.The Romans used spices such as cumin and coriander to help preserve food.
The spices came to Europe from countries to the east, such as the islands in the East Indies, Sri Lanka, and India. 2   Because of the long journeys involved, they were very expensive.
European sailors began to look for routes to these countries themselves in order to bring back the spices by sea.In 1498, a Portuguese explorer named Vasco Da Gama reached an East Indies island called Calicut. 3   In 1519, another Spanish explorer, Ferdinand Magellan, found a new trade route by sailing west across the Atlantic Ocean, around the southern tips of both South America and Africa, and back to Europe.
4   Portugal was the leader until the end of the 16th century.Spain was in control during much of the next 100 years.Then, Holland took over.The Dutch controlled the East Indies, but, in 1780, England defeated them in a famous war. 5   They treated the people there badly and made them submit to the British government.
India finally became independent from Britain in the 1940s.Today, it is still called “the land of spices”.In fact, at present India produces 2.5 million tons of spices each year and produced more types of spices than any other country.
A.For centuries, Arab traders had carried the spices over land and sold them to European countries.
B.For the next four centuries, Western countries raced each other for control of the spice trade in these new countries, which they called the “New World.”
C.Though they might not be as valuable today as gold or diamonds, spices are still big business around the globe.
D.Six years earlier, Spanish explorer Christopher Columbus had been looking for spices when he discovered America.
E.The English then moved from the islands into India.
F.The history of spice is almost as old as human civilization.
G.In those times, spices also helped keep meat from spoiling.

第二节:阅读表达(共5小题,每小题3分,满分15分)
阅读下面的短文,请根据短文后的要求答题(请注意问题后的字数要求)
To forgive (宽恕) may be great, but no one ever said it was easy. When someone has deeply hurt you, it can be very difficult to let go of your complaint. But forgiveness is possible — and it can be surprisingly beneficial to your physical and mental health.
So how do you start forgiveness? Try following these steps:
Calm yourself. To calm your anger, try a simple stress-management technique. “Take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, someone you love,” Luskin says.
Don’t wait for an apology. “Many times the person who hurt you has no intention of apologizing,” Luskin says. “They may have wanted to hurt you or they just don’t see things the same way. So if you ______________________, you could be waiting an awfully long time.”
Take the control away from your offender. Mentally replaying your hurt gives power to the person who cause you pain. “Instead of focusing on your wounded feelings, learn to look for the love, beauty and kindness around you,” Luskin says.
Try to see things from the other person"s perspective. If you understand that person, you may realize that he or she was acting out of ignorance, fear —even love. To gain perspective, you may want to write a letter to yourself from your offender’s point of view.
Don’t forget to forgive yourself. “For some people, forgiving
themselves is the biggest challenge,” Luskin says. “But it can rob
you of your self–confidence if you don’t forgive yourself.”
