Technology is the application(应用) of knowledge to production. Thanks to modern technology, we have been able to increase greatly the efficiency of our work force. New machines and new methods have helped cut down time and expense while increasing overall output. This has meant more production and a higher standard of living. For most of us in America, modern technology is thought of as the reason why we can have cars and television sets. However, technology has also increased the amount of food available to us, by means of modern farming machinery and animal breeding techniques, and has extended our life span via(通过) medical technology.
Will mankind continue to live longer and have a higher quality of life? In large measure the answer depends on technology and our ability to use it widely. If we keep making progress as we have over the past fifty years, the answer is definitely yes. The advancement of technology depends upon research and development, and the latest statistics(统计) show that the United States is continuing to pump billions of dollars annually(每年) into such efforts. So while we are running out of some scarce resources(少的资源) we may well find technological substitutes(代用品)for many of them through our research programs.
Therefore, in the final analysis the three major factors of production(land, labor and capital) are all influenced by technology. When we need new skills, on techniques in medicine, people will start developing new technology to meet those needs. As equipment proves to be slow or inefficient, new machines will be invented. Technology responds to our needs in helping us maintain our standard of living.

Believe it or not, optical illusion(错觉) can cut highway crashes.
Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. But stripes, called chevrons(人字形), painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down.
Now the American Automobile Association Foundation(基金会) for Traffic Safety in Washington D.C. is planning to repeat Japan’s success. Starting next year, the foundation will paint chevrons and other patterns of stripes on selected roads around the country to test how well the patterns reduce highway crashes.
Excessive (too great) speed plays a major role in as much as one fifth of all fatal traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards (danger) are the greatest curves, exit slopes, traffic circles, and bridges.
Some studies suggest that straight, horizontal bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bars.
Chevrons, scientists say, not only give drivers the impression that they are driving faster than they really are but also make a lane appear to be narrower. The result is a longer lasting reduction in highway speed and the number of traffic accidents.
小题1:The passage mainly discusses ________.
A.a new way of highway speed control
B.a new pattern for painting highways
C.a new way of training drivers
D.a new type of optical illusion
小题2: On roads painted with chevrons, drivers tend to feel that ________.
A.they should avoid speed-related hazards
B.they are driving in the wrong lane
C.they should slow down their speed
D.they are coming near to the speed limit
小题3: The advantage of chevrons over straight, horizontal bars is that the former ________.
A.can keep drivers awakeB.can cut road accidents in half
C.will look more attractiveD.will have a longer effect on drivers
小题4:The American Automobile Association Foundation for Traffic Safety plans to ________.
A.try out the Japanese method in certain areas
B.change the road signs across the country
C.replace straight, horizontal bars with chevrons
D.repeat the Japanese road patterns
小题5:What does the author say about straight, horizontal bars painted across roads?
A.They are suitable only on broad roads.
B.They are falling out of use in the United States.
C.They are ignored in a long period of time.
D.They cannot be used successfully to traffic circles.

A simple piece of clothesline hangs between some environmentally friendly Americans and their neighbors.
On one side stand those who see clothes dryers(干衣机) as a waste of energy and a major polluter of the environment. As a result, they are turning to clotheslines as part of the “what-I –can do environmentalism(环境保护主义).”
On the other side are people who are against drying clothes outside, arguing that clotheslines are unpleasant to look at. They have persuaded Homeowners Associations (HOAs) access the U.S. to ban outdoor clotheslines, because clothesline drying also tends to lower home value in the neighborhood. This had led to a Right-to-Dry Movement that is calling for laws to be passed to protect people’s right to use clotheslines.
So far, only three states have laws to protect clothesline. Right-to-Dry supporters argue that there should be move.
Matt Reck, 37, is the kind of eco-conscious(有生态意识的) person who feeds his trees with bathwater and reuses water drops from his air conditioners to water plants. His family also uses a clothesline. But on July 9, 2007, the HOA in Wake Forest, North Carolina, told him that a dissatisfied neighlzir had telephoned them about him clothesline. The Recks paid no attention to the warming and still dried their clothes on a line in the yard. “Many people say they are environmentally friendly but they don’t take matters in their own hands,” says Reck. The local HOA has decided not to take any action, unless more neighbors come to them.
North Carolina lawmakers are saying that banning clotheslines is not the right thing to do. But HOAs and housing businesses believe that clothesline drying reminds people of poor neighborhoods. They worry that if buyers think their future neighbors can’t even afford dryers, housing prices will fall.
Environmentalists say such worries are not necessary, and in view of global warming, that idea needs to change. As they say, “The clothesline is beautiful”. Hanging clothes outside should be encouraged. We all have to do at least something to slow down the process of global warming.”
小题1:One of the reasons why supporters of clothes dryers are trying to ban clothesline drying is that ____.
A.clothes dryers are more efficientB.clothesline drying reduces home value
C.clothes dryers are energy-savingD.clothesline drying is not allowed in most U.S. states
小题2:Which of the following best describes Matt Reck?
A.He is a kind-hearted man.B.He is an impolite man.
C.He is and experienced gardener.D.He is a man of social responsibility.
小题3:Who are in favor of clothesline drying?
A.housing businesses.B.Environmentalists.
C.Homeowners Associations.D.Reck’s dissatisfied neighbors.
小题4:What is mainly discussed in the text?
A.Clothesline drying: a way to save energy and money.
B.Clothesline drying: a lost art rediscovered.
C.Opposite opinions on clothesline drying.
D.Different varieties of clotheslines.

Some spiders hunt on the ground, others build webs to trap their food, but the grass water spider catches its prey by running along the surface of the water.
This special water spider lives on the grassy banks of streams where mosquitoes, damsel flies and other insects come to feed and breed.
Although it is one of the largest spiders in New Zealand, it has an unusual ability. It doesn’t disturb the water as it waits for its meal, and there is barely a ripple(波纹) when it skims(掠过) across the surface at lightning speed to catch its prey.
Grass water spiders deal swiftly with larger insects like damsel flies by pulling their heads under the water and holding them there until they drown.
After a meal, the grass water spider spends up to half an hour grooming(修饰) itself. It wipes its eight eyes, brushes its antennae(触角), and takes special care to clean the hairs on its body.
It is the hairs that trap tiny bubbles(泡沫) of air so that the spider can run down a blade(叶片) of grass and stay underwater for up to an hour when it is frightened. The hairs also keep the spider dry, even underwater.
It is only when the female spider is caring for the young that she does not hunt on the water. After mating, she produces a large egg sac(囊), which she carries around for five weeks. Once the eggs start to hatch, she attaches the sac to some blades of grass or a thistle. She then tears the sac open and releases the tiny spiders into the nursery web.
小题1:How does the grass water spider kill its prey?
A.in a webB.by drowningC.by poisoning D.with its antennae
小题2:the writer describes the special spider as “special” because _______.
A.it walks on waterB.it has eight eyes  
C.of its hairy appearanceD.of the way it produces its young
小题3:The passage tells us that the spider ______.
A.feeds grass and thistles to its young.    
B.lives on blades of grass under the water
C.lives in the grass on the banks of streams  
D.eats a meal once every five weeks
小题4:The purpose of the passage is to _______.
A.convince readers that spiders are dangerous  
B.indicate that the grass water spider is endangered
C.list all of the spiders that can be found in New Zealand
D.describe the characteristics of the grass water spider

Perhaps the most famous theory, the study of body movement, was suggested by Professor Ray Birdwhistell. He believes that physical appearance is often culturally programmed. In other words, we learn our looks—we are not born with them. A baby has generally informed face features. A baby, according to Birdwhistell, learns where to set the eyebrows by looking at those around-family and friends. This helps explain why the people of some areas of the United States look so much alike, new Englanders or Southerners have certain common face features that cannot be explained by genetics(遗传学). The exact shape of the mouth is not set at birth, it is learned after. In fact, the final mouth shape is not formed until well after new teeth are set. For many, this can be well into grown-ups. A husband and wife together for a long time often come to look alike. We learn our looks from those around us. This is perhaps why in a single country area where people smile more than those in other areas. In the United States, for example, the South is the part of the country where the people smile most frequently. In New England they smile less, and in the western part of New York State still less. Many southerners find cities such as New York cold and unfriendly, partly because people on Madison Avenue smile less than people on Peachtree Street in Atlanta. Georgia. People in Atlanta, Georgia. People in largely populated areas also smile and greet each other in public less than people in small towns do.
小题1:Ray Birdwhistell believes that physical appearance _______.
A.has little to do with culture
B.has much to do with culture
C.is ever changing
D.is different from place to place
小题2:According to the passage, the final mouth shape is formed _______.
A.before birthB.as soon as one’s teeth are newly set
C.sometime after new teeth are setD.around 15 years old
小题3:Ray Birdwhistell can tell what area of the United States a person is from by _______.
A.how much he or she laughsB.how he or she raises his or her eyebrows
C.what he or she likes bestD.the way he or she talks
小题4:This passage might have been taken out of a book dealing with ________.
A.physicsB.chemistryC.biologyD.none of the above

Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity(好奇). Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary(薪水) and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we’re finished with your lists, do you have questions of your own about science?”
After a long pause, a boy raised his hand, “Have you ever seen a grasshopper(蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?”
This began a set of questions that lasted nearly two hours.
Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical(符合逻辑的), complete and creative answers.
Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it comes to encouraging good behavior(行为). But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying “That’s interesting” or “I’d never thought of it that way before”, or coming up with more questions or ideas.
Never push a child to “Think”. It doesn’t make sense, children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target(目标) for your disagreement.
Lastly, show; don’t tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass(放大镜), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸发), set a pot of water to boil and let them watch the water level drop.
小题1:According to the passage, children are natural scientists, and to raise their interest, the most important thing for adults to do is _______.
A.to let them see the world around
B.to share the children’s curiosity
C.to explain difficult phrases about science
D.to supply the children with lab equipment
小题2:In the last sentence of the first paragraph, the word “lists” could best be replaced by ______.
A.any questionsB.any problems
C.questions from textbooksD.any number of questions
小题3:According to the passage, children can answer questions in a more logical, complete and creative way if adults ________.
A.ask them to answer quickly
B.wait for one or two seconds after a question
C.tell them to answer the next day
D.wait at least for three seconds after a question
小题4:In which of the following paragraph(s) does the author tell us what to say to encourage children in a science discussion?
A.The second and third. B.The fourth and fifth.
C.The fifth and sixth. D.The seventh.
小题5:The author mentions all of the following techniques for adults to share with their children’s curiosity except that adults should ________.
A.tell their children stories instead of reciting(背诵) facts
B.offer their children chances to see things for themselves
C.be patient enough when their children answer questions
D.encourage their children to ask questions of their own
