Scientific experiments can sometimes go wrong and when they do, the results may range from the disastrous to the troubling. One such experiment took place in South America about fifty years ago. Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen.
The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country’s bees. He imported a very active type of African bee from Tanzania and mated (交配) it with the more easygoing native variety to produce a new kind of bees. The new bees worked harder and produced twice as much honey. It seemed that Professor Kerr, for that was the scientist’s name, had a total success on his hands.
Then things began to go wrong. For some reason as yet unseen, but perhaps as a result of something in their environment, the new bees began to develop extremely attacking personalities. They became bad-tempered and easy to be angry, attacked the native bees and drove them from their living places.
But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings (叮) , began to attack its neighbors—cats , dogs, horses, chickens and finally man himself. A long period of terror began that has so far killed a great number of animals and about 150 human beings.
This would have been enough if the bees had stayed in Brazil. But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year. The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them.
60. Which of the following statements is right?
A. The results of the South American experiment have caused a serious trouble.
B. Scientific experiments in South America have proved to be wrong.
C. The results of the South American experiment are not yet certain.
D. It’s clear that scientific experiments in South America are not important.
61. The experiment mentioned in this passage was designed to _________.
A. increase the amount of honey in Brazil
B. make Brazilian bees more easy-going
C. increase the number of bees in Brazil
D. make African bees less active
62. Which of the following may be the cause of the new bees attacking personalities?
A. Their production of honey. B. Their hard work.
C. Their living environment. D. Their bad temper.
63. The last paragraph implies that __________.
A. the bees have been driven to Central and North America
B. The bees may bring about trouble in more countries
C. the bees must be stopped from moving north
D. the bees prefer to live in Brazil

举一反三
A device that stops drivers from falling asleep at the wheel is about to undergo(接受) testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called driver Alert, aims to reduce deadly road accidents by 20%--40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to tiredness.
Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots gives out a sound about every four minutes during a car journey. After each sound the driver must respond by pressing the steering wheel. A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.
68. How should a driver respond to the sounds from Driver Alert?
A. By sounding a warning. B. By touching the wristband.
C. By checking the driving time.D. By pressing the steering wheel.
69. We can learn from the text that the driver needs to stop for a break when his response time is ________
A. about 400 milliseconds B. below 500 milliseconds
C. over 500 milliseconds D. about 4 minutes
70. When the driver gets sleepy while driving, Driver Alert ______.
A. moves more regularly B. stops working properly
C. opens the window for the driver D. sounds more frequently and loudly
71. According to the text, Driver Alert ______.
A. aims to reduce tiredness-related accidents
B. has gone through testing at laboratories
C. aims to prevent drivers from sleeping
D. has been on sale for 12 months
第四部分阅读理解(共20小题,每小题2分,计40分)
通读下列短文,从各小题所给的A、B、C、D四个选项中选出最佳选项,并在答题卡上将该项涂黑。
I always feel sorry for world leaders busy dealing with fights between nations. When my three children were young, most days it was hard keeping my house from becoming a battlefield.
It got worse as they grew older. Three years ago, Zack, then 16, couldn’t make it through a day without making his sisters, Alex 11 and Taryn 9, angry.
My husband and I tried to be understanding the boy at such an age. We reasoned, punished, and left heartfelt notes on his bed about how he was hurting our family. His answer was “I say it because it’s true.”
I even tried telling the girls to fight back. Bad idea. Now I had three children at war. Whatever I said to them, they paid no attention. When there was no way out, I told everything to my sister, Mary, in an e-mail. She replied, “Don’t e-mail me. E-mail him.”
Our son was online every day, mailing and talking with his friends. Maybe he would actually hear me this way. I didn’t say anything different, but e-mail just took the tension away. There’d be no shouting or door banging. Zack wouldn’t feel under attack.
Zack didn’t reply for days. When he finally did, his entire message was four small words. I smiled when I read them: “You’re right. I’m sorry.”
The children still fought, of course, but Zack changed. Best of all, I now have a better way to talk with not one but three of them. I like it that they don’t tune me out as much as they used to. They like not having to listen to me shouting to them. Or as Alex says, “You’re so much nicer online.”
All I know is that the house is quiet. But we’re talking.
71. What was the trouble before the online talk in the family?
A. The writer failed to understand her daughters.
B. The children couldn’t get along peacefully.
C. The family found it difficult to keep the house clean.
D. The parents were not willing to talk with their children.
72. The writer once tried to deal with her son’s problem by _______.
A. talking with him about his pain
B. telling him about the truth of the family
C. telling her daughters to keep away from him
D. encouraging her daughters to fight against him
73. The writer e-mailed her sister _______.
A. to tell her about the family problem B. hoping she’d e-mail the boy
C. asking about child-raising D. to escape from the problem
74. The underlined phrase “tune me out” in the passage probably means _______.
A. quarrel with me B. get angry with me
C. pay no attention to me D. keep me out of their rooms
The plane journey from Papa Westray to Westray in the Orkney Islands takes just 96 seconds, covering a distance of little over a mile. Six teenagers are to take the Loganair service to Westray Junior High after the local ferry (渡轮) service stopped. They are all aged 13-14 and will be flown to and from school until the end of the year when the ferry is scheduled to return.
Papa Westray had a population of just 70 and no secondary school. Westray, home to more than 600 residents, has around 70 pupils at the Junior High and nine full-time teachers. The school provides education to Standard Grade level but pupils choosing to study for their Highers must travel to the Orkney capital Kirkwall.
The students will fly to Westray each Tuesday and stay with host families for two nights before catching a return flight on Thursday. Loganair operating the eight-seater service has changed its schedule to ensure the children get to school on time. The company says the flight, with an average flight time of 96 seconds, is the shortest in the world.
Jonathan Hinkles, the commercial director, said, “While it is a popular tourist route for many visitors to Scotland, it’s also an important lifeline to those residents who live, work or do business in the Orkneys and it will make all the difference to ensuring those children who live on Papa Westray can continue their schooling throughout winter.” Willie McEwen, acting head teacher at Westray Junior High, said, “we are delighted that Loganair has come forward with this solution. Our children will enjoy the flying especially as, at this time of the year, it can be quite dangerous on the boat. ”
83. Which of the following is TURE according to the passage?
The six students can get to school in less than a minute sometimes.
Westray has a small population though big in size.
The plane can hold ten people at most each time.
The six students take the flight to school every day.
84. What can we learn about Papa Westray from the passage?
A. It is very poor. B. It is located in Scotland.
C. It doesn’t have any school. D. It will have no ferry in the future.
85. How does Willie McEwen seem to feel about the flying?
A. Surprised. B. Worried. C. Satisfied. D. Disappointed.
86. Which of the following is the best title for the passage?
A. Children get lift to school on 96-second flight.
B. Six teenagers having trouble going to school.
C. The lucky students in Papa Westray.
D. The shortest flight in Papa Westray.
