Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in for an unwelcome surprise. The car is fitted with a remote immobilizer (锁止器), and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again.
The idea goes like this. A control box fitted to the car contains a mini-cellphone, a micro- processor and memory, and a GPS (全球定位系统) satellite positioning receiver. If the car is stolen, a coded cellphone signal will tell the control centre to block the vehicle's engine management system and prevent the engine being restarted.
In the UK, a set of technical fixes is already making life harder for car thieves. “The pattern of vehicle crime has changed,” says Martyn Randall, a security expert. He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum(="smallest)" of tools. But only if the car is more than 10 years old.
Modern cars are far tougher to steal, as their engine management computer won't allow them to start unless they receive a unique ID code beamed out by the ignition (点火) key. In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997.
But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner's keys. And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system.
If the stolen car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen. The hundred metres minimum avoids false alarms due to inaccuracies in the GPS signal.
Staff at the centre will then contact the owner to confirm that the car really is missing, and keep the police informed of the vehicle's movements through the car's GPS unit.
57. The remote immobilizer is fitted to a car to ______.
A. allow the car to lock automatically when stolen
B. help the police make a surprise attack on the car thief
C. prevent the car thief from restarting it once it stops
D. prevent car theft by sending a radio signal to the car owner
58. By saying “The pattern of vehicle crime has changed”, Martyn Randall suggests that ______.
A. it takes a longer time for the car thief to do the stealing
B. self-prepared tools are no longer enough for car theft
C. the thief has to make use of computer technology
D. the thief has lost interest in stealing cars over 10 years old
59. Why does the tracking system set a 100-metre minimum before sending an alarm to the operations centre?
A. To allow for possible errors in the GPS system.
B. To give the driver time to contact the operations centre.
C. To keep the police informed of the car's movements.
D. To leave time for the operations centre to give an alarm.
60. The operations centre will first ______ after receiving an alarm.
A. start the tracking system. B. contact the car owner.
C. block the car engine. D. locate the missing car.
Proudly reading my words, I glanced around the room, only to find my classmates bearing big smiles on their faces and tears in their eyes. Confused, I glanced toward my stone-faced teacher. Having no choice, I slowly raised the report I had slaved over, hoping to hide myself. “What could be causing everyone to act this way?”
Quickly, I flashed back to the day Miss Lancelot gave me the task. This was the first real talk I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. Since my idea of history came from an ancient teacher in my home country, I had never heard of that name before. As I searched the name of this fellow, it became evident that there were two people bearing the same name who looked completely different! One invented hundreds of uses for peanuts, while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice; flip (掷) a coin. Heads—the commander, and tails—the peanuts guy. Ah! Tails, my report would be about the great man who invented peanut butter, George Washington Carver.
Weeks later, standing before this unfriendly mass, I was totally lost. Oh well, I lowered the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American Revolution.” The whole world became quite! How could I know that she meant that George Washington?
Obviously, my grade was awful. Heartbroken but fearless, I decided to turn this around. I talked to Miss Lancelot, but she insisted: No re-dos; no new grade. I felt that the punishment was not justified, and I believed I deserved a second chance. Consequently, I threw myself heartily into my work for the rest of the school year. Ten months later, that chance unfolded as I found myself sitting in the headmaster’s office with my grandfather, now having an entirely different conversation. I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my option to skip the sixth grade. Justice is sweet! What did the author’s classmates think about his report?
| A．interesting | B．ridiculous. |
| C．boring. | D．puzzling. |
Why was the author confused about the task?
| A．He was unfamiliar with American history. |
| B．He followed the advice and flipped a coin. |
| C．He forgot his teacher’s instruction. |
| D．He was new at the school. |
The underlined word “burning” in Para. 3 probably means _______.
| A．annoyed | B．ashamed | C．ready | D．eager |
In the end, the author turned things around _______.
| A．by redoing his task |
| B．through his own efforts |
| C．with the help of his grandfather |
| D．under the guidance of his headmaster |
Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)—either recorded or real—may even prevent elephants from damaging farmer’s crops.
In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.
Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a tree close to each family.
From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.
Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn’t tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.

One day, I received a call from a colleague. He was about to give a student a zero for his answer to a physical problem, while the student claimed a perfect score. I was elected as their arbiter（仲裁人）. I read the examination problem: “Show how it is possible to determine the height of a tall building with the aid of a barometer（气压计）. ”The student had answered; "Take the barometer to the top of the building, attach a long rope to it, lower it to the street, and then bring it up, measuring the length of the rope. The length of it is the height of the building.”
The student had really answered the question completely, but the answer didn't confirm his competence in physics. I suggested the student try again. I gave him six minutes to answer the question, warning that the answer should show some knowledge of physics. Five minutes later, he said he had many answers and dashed off one, which read：“Take the barometer to the top of the building and lean over the edge of the roof. Drop the barometer, timing its fall with a stopwatch. Then, use the physical formula（公式）to calculate the height of the building.”
At this point, my colleague had to accept it, and then the student made almost full marks. I couldn't help asking the student what the other answers were. He listed many others, and then added, "Probably the best is to take the barometer to the administrator and said to him, ‘Sir, here is a fine barometer. If you tell me the height of the building, I will give it to you.”,
Then, I asked the student if he really did not know the conventional answer to this question. He admitted that he did, but said that he was fed up with high school and college instructors trying to teach him how to think.
The name of the student was Bohr who later was famous all over the world. He won the Nobel Prize for Physics in 1922.The student got a zero at the beginning because _____.
| A．the teacher wasn't satisfied with him |
| B．his answer wasn't complete or correct |

| D．his answer didn't show his knowledge of physics |
We know from the passage that _____.
| A．the student knew the expected answer |
| B．the administrator told Bohr the height |
| C．the author preferred Bohr's last answer |
| D．the teacher was a very stubborn person |
We can learn from the passage that _____.
| A．instructors can teach students how to think |
| B．arbiters can help students to get high scores |
| C．students should be given more freedom in thinking |
| D．teachers should make students use physical formulas |
What was Bohr's attitude toward his schooling?

The African elephant, which is the largest land animal remaining on earth, is of great importance to African ecosystem. Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna (大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat.
It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and under-bushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.What is the passage mainly about?
