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．"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 |
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． |
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． |
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． |

BEIJING (AFP) — Archeologists in China have uncovered more than 3，000 dinosaur footprints，state media reported，in an area said to be the world’s largest grouping of fossilized hones belonging to the ancient animals．
The footprints，believed to be more than 100 million years old，were discovered after a three-month excavation(发掘、出土) at a gully in Zhucheng in the eastern province of Shandong，the Xinhua news agency reposed．
The footprints range from 10 to 80 centimeters (4 to 32 inches) in length，and belonged to at least six different kinds of dinosaurs，including tyrannosaurs，the report said Saturday．
Wang Haijun，a senior engineer at the Chinese Academy of Sciences，said the footprints faced the same direction．Xinhua said．
This indicated a possible migration or a panic escape by plant-eating dinosaurs after an attack by predators(食肉动物)，Wang added．
Archeologists have found dinosaur fossils at some 30 sites in Zhucheng，known as“dinosaur city．”The region has seen two major digs since 1964，and experts say the discovery of so many dinosaurs in such a dense area could provide clues on how the animals became extinct millions of years ago．
Plans are being made to set up a fossil park in the area．
36．We can infer from the text that_____．
A．most of the footprints are more than 32 centimeters long
B．the footprints found belong to some predators
C．the dinosaurs were running in all directions because of an attack
D．the area is considered to be a perfect tour source
37．Which statement below is true according to the passage above?
A．The number of the footprints found is more than 3000．
B．The dinosaurs may live in an age 10，000，000 years ago．
C．The discovery of fossils may open a new age．
D．Archeologists still wish to find some more fossils．
38．The passage may be picked out from_____．
A．a magazine B．a science book C．a newspaper D．a students’ textbook
Some people don’t believe that driving more slowly can save lives. But the truth is that driving more slowly can help a person to avoid serious accidents.
The following chart shows the distance that it takes to stop a car at a given speed. The distance is measured in feet. The shaded area shows the driver’s thinking distance. That’s the distance it takes for the driver to react to a danger that he sees. The white area shows the car’s braking distance. That’s the distance it takes for the car to stop once the brakes are used. The number at the top of each bar shows the total number of feet that it takes to stop the car
72. According to the chart, what is the total number of feet needed to stop a car that is traveling at 50 miles per hour?
A. 55. B. 73. C. 128. D. 183.
73. What is the braking distance for a car that is traveling at 60 miles per hour?
A. 66 feet. B. 119 feet. C. 185 feet. D. 251 feet.
74. Which of the following statements about braking and speed is TRUE?
A. The braking distance is what it takes for the driver to react to a danger that he sees.
B. The speed of a car has a direct effect on the distance needed to stop the car.
C. The braking distance increases only when a driver drives faster than 50 miles per hour
D. Driving slowly can help a person to avoid all accidents
75. The underlined word probably means _____.
A. equipment for slowing down or stopping B. object that turns around

I love exploring new places. Whether I travel across America or around the world，a new adventure is always waiting. What I don’t always enjoy is the time spent 9,000 meters（30,000 feet）in the air. Tight spaces, long hours, and unexpected-problems can make air travel stressful. Follow these six tips to make your next flight a braze.
1. Make a checklist. Before you pack，make a checklist of everything you need and mark item off as you put them in your bag. Be sure you include important documents, such as your passport.
2. Pack light. You don’t need to pack your whole closet. Choose clothes that mix and match for more variety. Wear your largest shoes on the place to save room in your bag. And pack a few old items that you can leave behind to make more room for souvenirs(纪念品) on the way home.
3. Carry on essential （基本的）items. Unfortunately, dependable baggage service is hard to come by. When you fly, be sure to pack your medicine, important documents, and a change of clothes in your carry-on bag.
4. Pack water and snacks. No one wants to get stuck on a runway for hours without food, water. But bad weather or mechanical problems could leave you stranded（进退两难的）. Pack water and crackers in your carry-on. But leave fresh foods at home. Most countries won’t allow you to bring them across their borders.
5. Stretch your legs. More and more travelers suffer from blood clots caused by sitting too long in tight spaces. You can help prevent this problem by doing stretches in your seat taking short walks every hour.
6. Entertain yourself. A long trip can either mean hours of boredom or an exciting adventure. Plan ahead to keep yourself busy with books，magazines and portable CD player. Just don’t forget to bring extra batteries.
Research airlines before you book your reservations. For just a few dollars more，some airlines offer personal entertainment systems. Singapore Air gives you nearly 70 choices of movies，music channels, and other entertainment！
With a little planning ahead，you’ll be able to sit back and enjoy the ride.

The bicycle is the common sight in our daily life, as a great many Chinese use one every day. But you may not know its role in strengthening international relations, as it did in the case of US President George W. Bush’s visit to China .
President Bush arrived in Beijing on November 19, 2005 after he finished the APEC meeting in South Korea.He met with Chinese top leaders and achieved agreements on trade, Taiwan issue and more.
Although Bush’s trip was short as 40 hours, he managed to spare a moment to do some cycling. On November 20, he rode up and down a steep path at Laoshan Olympic Mountain Bike Course in Beijing’s suburbs.
Six young Chinese cyclists accompanied the president, who was dressed in a Chinese training uniform with the “Beijing 2008” logo (标志). He did not go along the arranged route and chose a more zigzag(曲折的) hiking path.
“How do you say, ‘take it easy on the old man’?” Bush joked to his partners before setting out.
“Compared with my bike path on the Crawford ranch (农场) , this one is greater and really difficult,” said Bush when his 45-minute ride ended. He said he will come to Beijing for the 2008 Olympic Games.
This is not Bush’s first cycle ride in Beijing. In 1975 at the age of 29, he visited the Chinese capital for the first time, when his father was head of the US liaison office (联络处) in Beijing, which Bush described as “fantastic”.
However, observers said Bush’s ride is much more than just his favorite pastime. It expressed friendliness with people in China, where the bicycle is an important part of life and culture.
According to the Washington Post, one of the major newspapers in the US, this was a specially arranged activity by the US Government, for they want to send the Chinese a sign of friendship. “The president is by no means hostile (有敌意的) to China,” it said.
64. What is the first paragraph mainly about?
A. Every Chinese has at least one bicycle
B. The bicycle is the common sight in our daily life
C. Bicycle can play a role in improving relationship between nations
D. President George W. Bush is fond of cycling
65. President George W. Bush went cycling ______.
A. wearing a T-shirt with the “Beijing 2008” logo
B. up and down a path on Laoshan Mountain
C. accompanied by six young Chinese policemen
D. along a more challenging way without arrangement
66. Bush said “take it easy on the old man” to his partners probably because ______.
A. he wanted to make them easy
B. he wanted to make a joke about them
C. he wanted to tell them it would be a more zigzag hiking path
D. he wanted to show them it would be a easy task for an old man
67. Which of the following is TRUE according to the passage?
A. Bush’s first cycle ride was in 1975.
B. Bush’s ride was specially arranged by the Washington Post.
C. Bush’s ride is more a sign of friendship than just his favorite pastime.
