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(符合邏輯的), 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(行為). 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(目標(biāo)) 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(放大鏡), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸發(fā)), set a pot of water to boil and let them watch the water level drop.

Jurassic Park could become a reality with dinosaurs making a comeback after a discovery last week. Scientists found remains of a dinosaur’s blood vessels(血管)and cells .In theory, DNA from these cells could be used to clone the longdead dinosaur.
A team from North Carolina State University found the remains in a fossil(化石)of the leg bone of a Tyrannosaurus rex(暴龍)in Montana, US.
The last dinosaurs on Earth died some 65 million years ago, but they left bits of themselves behind wherever they lived. Around the world ,dug-up bones and fossils have given scientists many ideas about what the animals were like.
Preserved by minerals, the newly discovered leg bone was hard. So the scientists used a liquid to dissolve(溶解)the minerals. A week later, the remaining material was soft and stretchy(有彈性的),which surprised the researchers.
Some of the materials appeared to be a network of blood vessels. Out of these, the researchers were able to squeeze(擠出)tiny , round, dark-red and deep-brown structures that seemed to be ancient blood cells.
Scientists are overjoyed by this discovery because most fossils come from hard body parts, like bones and shells, which last a long time. Soft tissues, like skin, muscle, and organs are very hard to find because they tend to break down more quickly.
Scientists think that the new discovery will help them to better understand how fossils form. Future finds should also help flesh out how the dinosaurs lived.
They were also very excited by the possibility of having some dinosaur DNA.From that scientists could create a real life “Jurassic Park”.
In the Hollywood movie, scientists reproduced dinosaurs from the DNA they found in a mosquito fossil and disaster soon followed.
小題1:Scientists are excited _________________________ .
A.because they have got dinosaur DNA
B.a(chǎn)bout making a movie called “Jurassic Park”
C.because they found the liquid to dissolve fossils
D.because it,s very hard to find soft tissues in fossils
小題2: The latest discovery can tell us       .
A.what the animals were likeB.how fossils form
C.how the dinosaur livedD.how to get dinosaur DNA
小題3:What does the underlined phrase“flesh out”mean in the article?
A.a(chǎn)dd more details or information toB.take more photos of
C.make the public know more aboutD.find the answer to
小題4:Why is the latest discovery very important?
A.It could make it possible to make dinosaurs return to the former position.
B.It could throw light on how dinosaurs lived many years ago.
C.It could prove what dinosaurs were like.
D.It could explain why dinosaurs died some 65 million years ago.

Education is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them. Our purpose is to fit them for life.
In some modem countries it has for some time been fashionable to think that by free education for all — one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degree; they refuse to do what they think “l(fā)ow” work; and, in fact, work with hands is thought to be dirty and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor; we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our towns…
In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability and, secondly, that we can realize that all jobs are necessary to society, and that is very bad to be ashamed of one’s work. Only such a type of education can be considered valuable to society.
小題1:The writer of the passage thinks that _______.
A.education can settle most of the world’s problems
B.free education for all probably leads to a perfect world
C.free education won’t help to solve problems
D.a(chǎn)ll the social problems can’t be solved by education
小題2:The writer wants to prove that _______.
A.our society needs all kinds of jobs
B.our society needs free education for all
C.a(chǎn) farmer is more important than a professor

A.to choose officials for the country
B.to prepare children mainly for their future work
C.to let everyone receive education fit for him
D.to build a perfect world

"The world's oceans are slowly getting more acidic,”say scientists. The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere.
The lowering of the waters’pH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.
Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century.
These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira. "And we predict the amount of future acidity will exceed(超過)anything we have seen over the last several hundred million years, let alone perhaps after rare disastrous events such as asteroid(小行星) impacts.”
However, it is not absolutely clear what that means for ocean life.Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean life forms may be more sensitive to pH changes.Coral reefs and other organisms whose shells contain calcium carbonate(小行星) may be particularly affected if the water's acidity levels keep going up, the team predict. They could find it much more difficult to build these structures in water with a lower pH.
In recent years some people have suggested storing carbon dioxide from power stations in the deep ocean as a way of dealing with global warming.But Dr Caldeira said that such a strategy should now be re-considered. "Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing-because in releasing CO2 into the atmosphere we warm the planet, and when CO2, is absorbed by the ocean, it reduces the amount of greenhouse warming.”
小題1:According to Dr Caldeira,__________ .
A.ocean absorption of carbon dioxide is a good thing
B.more oil fuels will be used in the near future
C.scientists may predict climate changes with computer models
D.the future situation of the amount of acidity is extremely serious
小題2:f the water's acidity level keeps rising,_________ .
A.ocean life whose structures contain calcium carbonate may be affected
B.the waters’pH value will become higher and higher
C.organisms living near the surface are more sensitive to pH changes
D.some disastrous events will occur more often than before
小題3:Most experts once believed storing carbon dioxide in the ocean would reduce________ .
A.the CO2 absorbed by the oceanB.the amount of greenhouse warming
C.the acidity of the oceanD.the gradual release of CO2
小題4:The purpose of this passage is to_________ .
A.show people the findings of a research teamB.inform people of how acid the ocean is now
C.introduce Dr Caldeira and his team's researchD.warn people of the higher level of CO2

Technology is the application(應(yīng)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(通過) 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(統(tǒng)計) 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(少的資源) 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.
小題1:What is the best title for the passage?
A.The definition of technologyB.Modern technology
C.The application of technologyD.The development of technology
小題2:Which is the main idea of the passage?
A.Modern technology is the key to the improvement of standard of living.
B.The three major factors of production (land, labor and capital) are all influenced by technology.
C.Technology is the response to our needs.
D.The United States is making great efforts to advance its technology.
小題3:According to the passage, people can live a long life with the help of _______.
A.higher quality of life B.medical technology

Some people think that as more and more people have televisions in their homes, fewer and fewer people will buy books and newspapers. Why read an article in the newspaper, when the TV news can bring you the information in a few minutes and with pictures? Why read the life story of a famous man, when a short television program can tell you all that you want to know?
Television has not killed reading, however. Today, newspapers sell in very large numbers. And books of every kind are sold more than ever before. Books are still a cheap way to get information and enjoyment. Although some books with hard covers are expensive, many books are printed today as paperbooks (平裝本), which are quite cheap. A paperback collection of short stories, for example, is always cheaper than an evening at the cinema or the theater, and you can keep a book for ever and read it many times.
Books are a wonderful provider of knowledge and pleasure and some types of books should be in every home. Every home should have a good dictionary. A good encyclopedia (百科全書), though expensive, is useful, too, because you can find information on any subject. Besides, you can have such books as history books., science textbook, cookbooks, and collections of stories and poems. Then from time to time you can take a book of poems off your shelves and read the thoughts and feelings of your favorite poets.
小題1:It can be inferred from the passage that ________.
A.TV programs are a chief provider of knowledge
B.cinemas are the best choice in getting information
C.reading is a cheap way of learning and having fun
D.newspapers are an expensive way to enjoy oneself
小題2:What does the sentences “Television has not killed reading, however ” underlined in the second paragraph suggest?
A.People only need reading, though.B.Reading is still necessary today.
C.Reading is more fun than television.D.Watching television doesn’t help reading.

PITTSBURGH – For most people, snakes seem unpleasant or even threatening. But Howie Choset sees in their delicate movements a way to save lives.
The 37-year-old Carnegie Mellon University professor has spent years developing snake-like robots he hopes will eventually slide through fallen buildings in search of victims trapped after natural disasters or other emergencies.
Dan Kara is president of Robotics Trends, a Northboro, Mass.-based company that publishes an online industry magazine and runs robotics trade shows. He said there are other snake-like robots being developed, mainly at universities, but didn’t know of one that could climb pipes.
The Carnegie Mellon machines are designed to carry cameras and electronic sensors and can be controlled with a joystick(操縱桿). They move smoothly with the help of small electric motors, or servos, commonly used by hobbyists in model airplanes.
Built from lightweight materials, the robots are about the size of a human arm or smaller. They can sense which way is up, but are only as good as their human operators, Choset added.
Sam Stover, a search term manager with the Federal Emergency Management Agency based in Indiana, said snake-type robots would offer greater mobility than equipment currently available, such as cameras attached to extendable roles.
“It just allows us to do something we’ve not been able to do before,” Stover said, “We needed them yesterday.”
He said snifter dogs are still the best search tool for rescue workers, but that they can only be used effectively when workers have access to damaged building.
Stover, among the rescue workers who handled the aftermath (后果) of Hurricane Katrina, said snake robots would have helped rescuers search flooded houses in that disaster.
Choset said the robots may not be ready for use for another five to ten years, depending on funding.  
小題1:Which institution is responsible for the development of Choset’s robots?
A.Robotics Trends.B.Pittsburgh City Council.
C.Carnegie Mellon University.D.Federal Emergency Management Agency.
小題2:Choset believes that his invention ______.
A.can be attached to an electronic arm
B.can be used by hobbyists in model airplanes
C.can find victims more quickly than a snifter dog
D.can sense its way no better than its operators
小題3:By saying “We needed them yesterday” (paragraph 7), Stover means that snake-like robots _____.
A.could help handle the aftermath of Hurricane Katrina
B.would have been put to use in past rescue work
C.helped rescuers search flooded houses yesterday
D.were in greater need yesterday than today
小題4:What is the text mainly about?
A.Snake-like robots used in industries.
B.Snake-like robots made to aid in rescues.
C.The development of snake-like robots.
D.The working principles of snake-like robots.

We now think of chocolate as sweet, but once it was bitter. We think of it as a candy, but once it was a medicine. Today, chocolate can be a hot drink, a frozen dessert, or just a snack. Sometimes it’s an ingredient(配料) in the main course of a meal. Mexicans make a hot chocolate sauce called mole and pour it over chicken. The Mexicans also eat chocolate with spices(香料) like chili peppers.
Chocolate is a product of the tropical cacao tree. The beans taste so bitter that even the monkeys say “Ugh!” and run away. Workers must first dry and then roast the beans. This removes the bitter taste.
The word “chocolate” comes from a Mayan word. The Mayas were an ancient people who once lived in Mexico. They valued the cacao tree. Some used the beans for money, while others crushed them to make a drink.
When the Spaniards came to Mexico in the sixteenth century, they started drinking cacao too.Because the drink was strong and bitter, they thought it was a medicine. No one had the idea of adding sugar. The Spaniards took some beans back to Europe and opened cafes. Wealthy people drank cacao and said it was good for the digestion.
In the 1800s, the owner of a chocolate factory in England discovered that sugar removed the bitter taste of cacao. It quickly became a cheap and popular drink. Soon afterwards, a factory made the first solid block of sweetened chocolate. Later on, another factory mixed milk and chocolate together. People liked the taste of milk chocolate even better.
Besides the chocolate candy bar, one of the most popular American snacks is the chocolate chip cookie. Favorite desserts are chocolate cream pie and, of course, an ice cream sundae with hot fudge sauce.  
1. It was ________that discovered sugar could remove the bitter taste of cacao.
A. The workers in the chocolate factory       B. The Spaniards
C. The people in England                 D. The owner of a chocolate factory

D. Workers must dry and roast the beans to remove the bitter taste.
3. The Spaniards think that cacao was a medicine because________
A. it was strong and bitter.    B. it was good for digestion.
C. it cured man’s diseases.     D. it was a kind of drink for good health.
4. Which is the right time order of the events regarding chocolate?

A. a-b-c-d-e           B. c-d-e-b-a    C. c-d-a-b-e          D. c-d-b-e-a
5. It can be inferred from the passage that ________.
A. chocolate can be a hot drink, a frozen dessert, or a candy bar
B. Mexicans like chocolate very much
C. chocolate is a product of the cacao tree
D. people liked the taste of chocolate mixed with milk
