B
The following are the results of the tests done by “Family and Home Magazine” on some Pocket Tape-Recorders on the market now.
Pearlcorder S702 $64
This simple model at the bottom of the Olympus range scored the most points for its excellent quality of recording. Background noise hardly affects the sound and recording from a pocket is perfectly possible, but it doesn’t turn off automatically.
Tape length: 30minutes per side. Weight: 240g.
Sony M9   $49.95
Small and very good looking, Sony’s latest offering scored most for its appearance. Sounds clear, but there is slight machine noise. The big control buttons are a great improvement on some of the complicated little controls on other tape-recorders. It doesn’t switch off automatically, but a red light shows if the machine is still running.
Tape length: 60minutes per side. Weight: 195g.
Sony M400  $115
Lots of little control buttons that make a noise are difficult to use. Recording is good but machine noise loses points. Tape counter and automatic switch-off when tape has finished recording or rewinding are useful.
Tape length: 60 minutes per side. Weight: 230g.
Imperial OEM MC7  $ 29.95
Cheap and simple compared with the rest, but recording is good as long as there is no background noise. Use only its own-make of cassette. No light to show it is on; no fast-forward button and the record button makes a loud noise.
Tape length: 30 minutes per side. Weight: 285g.
Philips 585  $80
Handsome and simple to use, but recording is very poor at more than the recommended distance of 5 cm-designed for dictation. No recording light.
Tape length: 15 minutes per side. Weight: 220g.
46. The machine that produces the best recording with the least unwanted noise is __.
A. Pearlcorder S 702     B. Sony M9
C. Sony M400          D. Imperial OEM MC7
47. If you want a machine which turns off automatically and weighs very little you should choose _____.
A. Pearlcorder S 702   B. Sony M9  C. Sony M400  D. Philips 585
48. Which of the following allows you to record longest but costs you least?
A. Philips 585   B. Imperial OEM MC7  C. Sony M400   D. Sony M9
 
46-48    ACD

Winter is dangerous for drivers because it’s so difficult to know what is going to happen and accidents take place easily. Bad weather can be waiting to meet you. Ice might be hiding under the snow, waiting to send you off the road. The car coming towards you might suddenly move across the road. Here are two rules for driving safely on icy roads:
Rule Number One is to drive smoothly. Irregular movements can make a car very difficult to manage. So each time you either turn the wheel, touch the brake or increase your speed, you must be as gentle and slow as possible. Just imagine you are driving with a full cup of hot coffee on the seat next to you. You should drive carefully enough in order that you wouldn’t get the coffee out of the cup.
Rule Number Two is to pay attention to what might happen. The more ice there is, the farther you have to look down the road. Test how long it takes to stop by gently braking. Remember that you may be driving more quickly than you think. Generally speaking, allow double your normal stopping distance when the road is wet, three times this distance on snow, and even more on ice. Try to stay in control of your car at all times, or you will get into trouble.
49. Driving in winter is dangerous because _________.
A. drivers usually have too much coffee      B. people drive three times faster than usual
C. unexpected things may often happen              D. people drive more gently and slowly
50.Rule Number One mainly tells us _________.
A. to drive fast on snowy roads                   B. to increase the driving speed
C. to manage your car irregularly                D. to drive smoothly on icy roads
51.Which of the following can be the best title of the passage?
A. Winter Driving  B. Careless Driving   C. Traffic Accidents         D. Bad Weather
52.Where do you think you might read such a passage?
A. In dictionaries.   B. In cookbooks.     C. In advertisements.  D. In magazines.

D
Global warming is the process of earth’s atmosphere heating up. Over the last 100 years, the average temperature of earth’s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth’s climate.
Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment are some of the reasons that the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.
The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, prevent heat energy from escaping back into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.
Today, most scientists are pretty sure that the rising temperature can’t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.
The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.
Over the past last 100years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.
68. What is mainly talked about in this passage?
A. The melting of glaciers.                B. Global warming.
C. The world’s weather.                  D. The earth’s temperature.
69. What causes global warming according to scientists?
A. Human activities.                     B. The nature itself.
C. The earth’s atmosphere.                D. New discoveries
70. How can greenhouse gases make the globe warm?
A. They keep heat in the atmosphere   
B. They let the heat go out into space.
C. They release heat into the air.       
D. They can make the other gases warm.
71. From the passage we can see that global warming will bring about _________.
A. the pollution in the atmosphere            B. natural disasters
C. population pollution                     D. the rise of glaciers

Computer mouse is no longer so strong. A Canadian engineer has invented a system that enables a computer user to push a cursor(光标)across a screen simply by moving his or her nose .He calls his nose-driven mouse a mouse.
The inventor ,Dmity Gorodnichy ,came up with the idea for the mouse while building computer software that would help astronauts operate the Canadarm—a long robotic arm on the U.S. space shuttle .His system employs a web-camera that recognizes a computer user’s nose from 25 pixels ,or points of light. Dmity chose the nose because its position remains relatively constant no matter which way the head moves .The system keeps track of the pixels, and the user matches the movements of his or her nose with the progress of the cursor across the screen.
The mouse keeps track of the eyes too. Two blinks(眨眼)are a “double click,” which turns the mouse on or off.
The mouse has received mixed comments from those who hold opposite opinions. One called it “a pointless waste of technology” . Another predicted that the nouse will fail to catch on because it makes users “look silly.” Dmity has already adapted the nouse for NousePong, a video game ,and NousePaint ,a drawing program.
He also predicts that the mouse will attract the people who have suffered from specific disease-pain ,senselessness ,or trembling in the hand caused by the frequent repetition of movements of the wrist and fingers ,such as typing at a computer keyboard .His next plan is to adapt the nouse for use by paralyzed(瘫痪)patients in hospitals .With two blinks of the eyes ,patients could double-click for help.
72.The best title for this passage is probably      .
A.Mouse Driven by Nose
B.Cursor Moved Without fingers
C.New Computer System for Astronauts
D.New Type of Mouse for Patients
73.The nouse is a system working by means of          .
A.keeping track of the points of light
B.moving one’s nose or blinking
C.moving cursor across the screen
D.matching the user’s nose with eyes
74.The underlined phrase “catch on” means “       ”.
A.become popular     B.be used      C.get improved        D.be made
75.Dmity predicts that the nouse will be more used to help          .
A.those who have eye trouble
B.develop a video game and drawing program
C.those traveling in space
D.the disabled with the hand and paralyzed patients

C
Organic food has no nutritional or health benefits over ordinary food,according to a major study.
Researchers from the London School of Hygiene & Tropical Medicine said consumers were paying higher prices for organic food because of its imagined health benefits,creating a global organic market worth an estimated $48 billion in 2007.
A systematic review of 162 scientific papers published in the scientific literature over the last 50 years,however,found there was no significant difference.
“A small number of differences in nutrient content were found to exist between organically and conventionally(通常)produced foodstuffs,but these have nothing to do with public health,” said Alan Dangour ,one of the report's authors.
“Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority .”
The results of research,which was commissioned by the British government’s Food Standards Agency,were published in the American Journal of Clinical Nutrition.
Sales of organic food have fallen in some markets,including Britain,as a slowdown in economic growth has led consumers to cut back on purchases.
The Soil Association said that growth in sales of organic products in Britain slowed to just 1.7percent,well below the average annual growth rate of 26 percent over the last decade.
64. Why does organic food cost more than conventionally produced food?
A. Because people think they are much healthier.    B. Because they are more delicious.
C. Because people prefer organic food.            D. Because they sell better.
65. According to the study,organic food is_________ than conventionally produced food.
A. much healthier           B. better       C. no healthier           D. less healthier
66. Sales of organic food have fallen because of___________.
A. high price            B. economic decline       C. bad service           D. poor quality
67. Where can you find this passage in a newspaper?
A. Economy            B. Science.      C. Food & Nutrition      D. Fashion

E
There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration (集中)of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution.
Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of coal and oil is creating a “greenhouse effect” - raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.
Another view, less widely held, is that increasing particular matter in the atmosphere is preventing sunlight and lowering the earth’s temperature - a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen though one recent government reports that the greenhouse effect is very possible. Perhaps, if we are lucky enough, the two tendencies will offset(抵消)each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people don’t think about the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worth?
72. As pointed out at the beginning of the passage, people used to think that air pollution ________.
A. caused widespread damage in the countryside
B. affected the entire eastern half of the United States
C. had damaged effect on health
D. existed only in urban and industrial areas
73. As to the greenhouse effect, the author ________.
A. shares the same view with the scientists
B. is uncertain of its happening
C. rejects it as being ungrounded
D. thinks it will destroy the world soon
74. It can be concluded from the last paragraph that ________.
A. lowering the world’s temperature only a few degrees would lead major farming areas to disaster
B. raising the world’s temperature only a few degrees would not do much harm to life on earth
C. almost no temperature variations have occurred over the past decade
D. the world’s temperature will remain constant in the years to come
75. This passage is mainly about ________.
A. the greenhouse effect
B. the burning of coal and oil
C. the potential effect of air pollution
D. the likelihood of a new ice age

Research on the human brain has been attracting more and more scientists in recent years, just like the booming hi-tech industry. One of the latest research topics is how to change the human brain or combine the computer and the human brain, i.e. to transplant a chip into a human brain. This idea may make everyone’s dream come true. If we compare a human brain to a hard disc(硬盘), what the scientists are doing is to enlarge the capacity of the hard disc. For the time being, there are some difficulties in such transplant experiments, but scientists never give up.
Experiments have started on animals. In 1996, a transplant experiment performed at the Defense and Military Physiology Research Institute in the U.S. turned a bear into a dolphin.
The dolphin was named Ted, and the bear was named Tallin. Using the most advanced technology available, deep and detailed images were made of the memory area in Ted’s brain containing information about swimming by the scientists. They obtained a series of useful information, the signals transferred by the nervous system. Such information was saved into a button-sized chip, which was then transplanted into the action memory area in Tallin’s brain. The information saved on the chip was released by means of electric power.
Recently, another comprehensive memory transplant was performed at the Motor Nerve Research Institute of the University of California. The comprehensive memory transplanted in the experiment included actions, moods, logic, words, images, etc. The experiment involved an entire transplant of the memory area. This was the largest such experiment done so far.
The transplant was performed making a transfer from a dog named “Genius” to a dog named “Idiot”. “Genius” could understand and follow up to 100 gestures and orders made by its master. It was a real genius in memorizing. “Idiot” was the younger brother of “Genius”. It had no contact with people at all since its birth. It became an animal with nothing in its brain, without any memory.
The operation was a complete success. When the two dogs woke up, “Idiot” had grasped all the abilities “Genius” possessed; it was good at memorizing and sensible. It could follow every gesture and any command given by its master. But “Genius” gave no response to its master, and in fact did not recognize him at all.
57. The purpose of the experiment is _____.
A. to combine the computer and the human brain    
B. to enlarge the capacity of human brain
C. to make some stupid dog turn clever          D. to make bear swim
58. Which of the following statements is TRUE?
A. The scientists transferred a button-sized chip with useful information in Tallin’s brain.
B. The first comprehensive memory transplant was performed at the Motor Nerve Research University.
C. The second experiment wasn’t an entire transplant of the memory area.
D. The Idiot was an animal with memory before brain experiment
59. What does the underlined word “success” refer to?
A. The two dogs woke up.
B. They were both good at memorizing.
C. The Idiot grasped all the abilities of Genius.
D. The Genius grasped all the abilities of Idiot.
60. According to the text, we can infer _____.
A. a person can know more after the experiment
B. a bear can swim after being transferred a chip with related useful information
C. a dog can become clever after entire transplant of the memory area
D. it is really good for animals to have been involved in the transplant experiment

C
A long-awaited final report from the Food and Drug Administration (FDA) concludes that foods from healthy cloned animals and their offspring(后代) are as safe as those from ordinary animals, effectively removing the last US regulatory(监管的) barrier to the marketing of meat and milk from cloned cattle, pigs and goats.
The 968-page final report, not yet released but obtained by The Washington Post, finds no evidence to support people’s concerns that food from clones may have hidden risks.
But, recognizing that a majority of consumers are wary of food from clones—and that cloning could damage the good image of American milk and meat—the report includes hundreds of pages of raw(原始的) data so that others can see how it came to its conclusions.
The report also admits that human health concerns are not the only subject raised by the coming-out of cloned farm animals.
“Moral, religious and ethical concerns have been raised,” the agency notes in a document accompanying the report. But the report is “exactly a science-based evaluation.” It reports, because the agency is not authorized by law to consider those subjects.
In practice, it will be years before foods from clones make their way to store shelves in large quantities, in part because the clones themselves are too valuable to kill for meat or milk. Instead, the expensive animals—replicas(复制品) of some of the finest farm animals ever born—will be used firstly as breeding stock to create what supporters say will be a new generation of superior farm animals.
When food from those animals hits the market, the public may yet have its say. FDA officials have said they do not expect to require food from clones to be labeled as such, but they may allow foods from ordinary animals to be labeled as not from clones.
64.   What can we infer from the first paragraph?
A.    FDA has waited for a long time to get this final report.
B.    Products from cloned animals have been put into the market before.
C.    People are having the products from cloned animals safely.
D.    There have been once opposite opinions against cloned products.
65.   What does the underlined word “wary” mean?
A. Disappointed.           B. Careful.         C. Fond.                                 D. Proud.
66.   It will be a few years before foods from clones come into the market, partly because _____.
A.    people have little knowledge of the cloned animals
B.    supporters can’t give powerful evidence to support that
C.    the few cloned animals will first be used to create superior animals
D.    they are a new generation for the customers and are too valuable for the customers
67.   What can we conclude from the passage?
A.    FDA officials encourage people to eat more food from clones.
B.    FDA officials think the food from clones will sell better than ordinary food.
C.    People only worry about the health problems when it comes to foods from the clones.
D.    All the foods will not have detailed labels on them.
