About ten men in every hundred suffer from color blindness in some way. Women are luckier, only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man can not see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods” but these are used for seeing when it is nearly dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes (蚊子) like blue but do not like yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible (看不見的) colors around.
小題1:Why do some people say it is safer to be driven by women?
A.Women are more careful.
B.There are few color-blind women.
C.Women are fonder of driving than men.
D.Women are weaker but quicker in thinking
小題2:This passage is mainly about ________.
A.color and its surprising effects
B.women being luckier than men
C.danger caused by color blindness
D.color blindness
小題3:According to the passage, with the help of the “cones”, we can ________.
A.tell orange from yellow
B.see in weak light
C.kill mosquitoes
D.tell different shapes
小題4:We can attract and kill mosquitoes by using a ________.
A.red lightB.yellow lightC.blue lightD.green light

小題1:B
小題2:D
小題3:A
小題4:C

I give two examples as to why intelligent life may not actually exist, though I admit that for me, or even for a physicist who devoted his or her entire life to researching and studying the universe, it's shocking to claim that completely no life exists elsewhere.
Keeping that in mind, I'd just like to consider conditions elsewhere in the known universe. You really only need to look at our own solar system or the Earth at certain periods in its own history to appreciate that most places are much worse and much less suitable for life than our mild, watery globe.
So far, space scientists have discovered about seventy planets outside the solar. But it appears that if you wish to have a planet suitable for life, you just have to be very lucky, and the more advanced the life is, the luckier you'll have to be. I'm by no means a space observer, but I can recognize some particularly fortunate breaks we've had on the Earth. For example:
We are, to a degree, at the right distance from the perfect type of star, the one that is big enough to radiate a huge amount of energy, but not so big as to bum itself out quickly. Had our sun been ten times as huge, it would have burnt out completely after only ten million years, instead of ten billion and surely we would not exist. Too near, everything on the Earth would have boiled and withered away; any further, everything would have frozen over.
The universe is a surprising place, and our existence within it is a wonder. If a long and unimaginably complex sequence of events dating back 4.6 billion years or so hadn't happened in a particular manner at a particular time --if, to take just one example, the dinosaurs hadn't been wiped out by a meteor(流星)--we might still be a few centimeters long, with whisker(胡須) and a tail, and you'll be reading this in a cave somewhere.
小題1:What's the best title for this passage?
A.No Life Exists out of the Earth
B.Seventy Planets Discovered
C.A Place Full of Wonders
D.Perfect Conditions for Life
小題2:What makes the Earth more suitable for life than other planets in the solar system?
A.The Earth is the only planet that can receive energy from the sun.
B.The sun is at the right distance from us and in proper size.
C.The distance between the planets was neither too long nor too near.
D.The dinosaurs were no longer a threat to the Earth.
小題3:What does the underlined phrase "withered away" in the 4th paragraph mean?
A.Exploded.B.Expanded.C.Floated away.D.Dried and died.
小題4:Where does the text probably come from?
A.A history book.B.A magazine.C.A science fiction.D.A famous novel.

All too often, a choice that seems sustainable(可持續(xù)的)turns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol(乙醇) for fuel from corn. Corn is a renewable resource —you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea. 
One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that’s not the end of the problem. Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food. That result leads to turning the fallow land –including, in some cases, rain forest in places such as Brazil—into farmland, which in turn gives off lots of carbon dioxide (CO) into the air. Finally, over many years, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that it might not help.
You cannot really declare any practice “sustainable” until you have done a complete life-cycle analysis of its environmental(環(huán)境的) costs. Even then, technology and public keep developing, and that development can lead to unforeseen and undesired results. The admirable goal of living sustainably requires plenty of thought on an ongoing basis.
小題1:What might directly cause the loss of the forest according to the text?
A.The growing demand for energy to make ethanol
B.The increasing carbon dioxide in the air
C.The greater need for farmland
D.The big change in weather.
小題2:The underlined word “it” in the second paragraph refers to “           ” 
A.the energy benefitB.the forest loss
C.climate changeD.burning ethanol
小題3:The author thinks that replacing gas with corn ethanol is           . 
A.impracticalB.a(chǎn)cceptableC.a(chǎn)dmirableD.useless
小題4:What does the author mainly discuss in the text? 
A.TechnologyB.Sustainability
C.Ethanol energyD.Environmental protection

What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to? The good news is that we can. In fact, we are swimming in it--- literally.
Hydrogen is one of the building blocks of the universe. Our own sun is basically a big, dense cloud of the stuff. And hydrogen can be used to create electricity for power, heat and light.
The problem is that hydrogen is everywhere and nowhere at the same time. It does not exist as a material on its own, but is always part of something else. So it has to be separated before it can be used.
Most commercial hydrogen in use now is created from natural gas. As oil will start to run out in around the year 2030, it makes sense to produce as much hydrogen as possible as soon as we can. But natural gas supplies will also begin to run out soon after. Another source is needed.
Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen “fuel cells” for computers and mobile phones have already come on to the market. Auto companies have also invested over US $2 billion in the production of hydrogen fuelled cars.
The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution. The only by-product of creating hydrogen is pure drinking water--- something that is very scarce in many parts of the world. But that is not where the good news ends. Once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth’s population that has no electricity.
And electricity creates wealth. In South Africa over the last decade there has been a large programme of electrification. Thanks to the programme, people do not have to spend their days looking firewood to burn for heat. And with electric light, they can work long into the night.
Some scientists see radical changes in the way the human race co-operates. Hydrogen creates electricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web,” which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source.
Like all dreams of the future, it seems very far away. But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to end oil dependency and spend more time and money on hydrogen resource. So maybe the threat of war is not a completely bad thing for the future of the human race.
小題1:What does the underlined word “it” in the last but one paragraph refer to?
A.wealthB.hydrogenC.electricity D.fuel
小題2:What is the problem with using hydrogen as energy?
A.It has by-products.
B.It has to be separated from other materials.
C.It will make energy too cheap.
D.It is too far away from us.
小題3:Why does the author give the example in the last but one paragraph ?
A.To tell us that we produce energy while using hydrogen power.
B.To tell us that hydrogen power does not produce pollution.
C.To show hydrogen power can stop war.
D.To show hydrogen power is cheap.
小題4:What is the author’s attitude about the future?
A.skepticalB.negative C.indifferent D.positive
小題5:What is the passage mainly about?
A.war and energy B.the future of hydrogen as an energy resource
C.the disadvantages of oilD.How to end war

Many parents have learned the hard way that what sounds like open communication is otfen the very thing that closes a youngster’s ears and mouth, One common mistake is the Lecture, the long monologue that often starts with “When I was your age……”Eighteen –year –old Kelly calls lectures “Long , one-side discussions in which I don’t say much.”
Kids reflexively(條件反射地)shout down in the face of a lecture , Their eyes glaze over(呆滯),and they don’t register any incoming information , Listen to 13-year –old Sarah describe her least favorite times with her mom and dad, “First, they scream, Then comes the“We’re so disappointed’ speech , Then the ‘I never did that to my parents’ lecture begins , After that, even if they realize how ridiculous they sound, they never take it back’”.
Lines like “When you have children of your own, you’ll understand” have been seriously said by parents since time immemorial, But many of our expert parents, like Bobby , a registered nurse and mother of three, feel that by falling back on cliches(陳詞濫調(diào))to justify our actions, we weaken our position.
Since kids are creatures of here and now, the far-off future has no relevance to them, Therefore ,good communicators like Bobby suggest, “Give specific reasons for your actions in present language:‘I’m not letting you go to the party because I don’t think there will be enough adult supervisions(監(jiān)護(hù))”。
Betty, who lives in Missouri ,uses and indirect approach, “I find that warnings are accepted more readily if I discuss a news article on a subject I am concerned about, My husband and I talk about it while our children absorb the information, Then they never think I’m preaching(布道)”.
This really helped when Betty’s kids began driving , Instead of constantly repeating “Don’t drink; don’t speed”, She would talk about articles in the paper and express sympathy for the victims of a car crash, Betty made no special effort to draw her kids into the conversation, She depended on a teenager’s strong desire to put in his opinions—especially if he thinks he isn’t being asked for them.
小題1:The purpose of the passage is to       
A.compare two ways of parents’ communicating with their kids
B.give parents advice on how to communicate with their kids
C.explain why kids won’t listen to their parents
D.introduce kids’ reaction to the communication between them and their parents

A.Kids won’t listen to their parents because they think what their parents say is boring
B.Many kids think they have no right to express their own opinions
C.Some kids think their parents should apologize when they are wrong
D.Kids don’t like any discussion at all.
小題3:What does the underlined word in the first paragraph mean?
A.獨(dú)白B.對話C.插話D.討論
小題4:Which of the following topic may appeal to kids?
A.Parents own experience
B.Kids possible life in the future
C.Something related to kids’ present life
D.What parents have done to their own parents
小題5:In order to make kids follow their advice, parents should

Passage 1
The information Highway is the road that links computer users to a large number of on-line services; the Web, e-mail, and software, to mention just a few. Not long ago, the information Highway was a new road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems, forcing the system to close down for repair. Naturally, accidents will happen on such a crowed road, and usually victims are some files, gone forever. Then, of course, there’s Mr. Cool, with his new broad-band connection, who speeds down the highway faster than most of us can go. But don’t trick yourself; he pays for that speeding.
Passage 2
Want to know more about global warming and how you can help prevent it? Doctor Herman Friedman, who is considered a leading expert on the subject, will speak at Grayson Hall next Friday. Friedman studied environmental science at three well-known universities around the world before becoming a professor in the subject. He has also traveled around the world observing environmental concerns. The gradual bleaching (變白) of the Grate Barrier Reef, which came into the public eye in 2002, in his latest interest.

How to Tell If Someone Is Happy or Sad on the Phone
Scientists have come up with some researches on what makes different types of people“tick”.
The scientists at the University of Cambridge have developed new mobile phone technology called Emotion Sense that can tell if a caller is happy, angry or sad.
Scientists hope to fit the speech recognition system to standard mobile phones and use it to determine emotions—it will also use a GPS tracking system to log where the call is made.
 And they’ve already made some pretty major breakthroughs into really getting under the skin of us humans.
The results from the pilot scheme make interesting scientific reading. Among the key revelations (﹦facts) are that callers feel happier at home and sadder at work.
To break it down, scientifically, it shows 45 percent of all emotions produced at home are “happy”and 54 percent of emotions at work are “sad”.
Meanwhile, people show more “intense”(﹦nervous) emotions in the evening than they do in the morning.
Of course, this could just be because most people feel too tired in the morning to get overly “intense”. Eating breakfast and getting to work on time is usually enough of an achievement.
Anyway, the Emotion Sense technology has been developed by psychologists(心理學(xué)家) and computer scientists who say it uses speech recognition software and phone sensors(傳感器) attached to standard smart phones to judge how callers’ emotions are changed by everyday factors.
The sensors analyze voice samples and these are then divided into five categories: happiness, sadness, fearfulness, anger or neutral-—boredom or passivity(消極) would fit into this last category.
小題1:How many emotions can the sensors tell?
A.TwoB.ThreeC.FourD.Five
小題2:What does the underlined sentence mean?
A.Scientists have put something testing people’s emotions under humans’ skin.
B.There were some breakthroughs in this technology in getting something from people’s skin.
C.In this technology, people’s skin was broken through.
D.There were improvements in testing people’s emotions.
小題3:Why do most people feel less intense in the morning than in the evening?
A.Because morning is the start of a new day.
B.because they feel too tired in the morning.
C.Because of humans’ physiological structure.
D.Because of the fresh air and bright sunlight.
小題4:Which of the following hasn’t been put into the standard mobile phones?
A.Speech recognition software.B.Phone sensors.
C.GPS sensors.D.Translation system.

The ozone layer(臭氧層) is a thin layer of gas around the earth. It forms a special “blanket” around the planet. This “blanket” protects the earth from dangerous rays produced by the sun. Without the ozone layer, the earth’s climate could warm to dangerous levels. This increase in temperature would threaten our survival. Scientists recently have discovered a hole in the ozone layer above the Antarctica. Now there is great concern that this warning has started, endangering all life on the earth.
What has destroyed part of the ozone layer? Scientists do not know for sure. They suspect that our popular spray cans (噴漆罐) have played a part in the damage. Many spray cans contain dangerous gases. These gases might have destroyed the ozone layer fifteen miles above the earth’s surface, The chemicals used in refrigerators (冰箱) and air conditioners may contribute to the problem, too.
Many scientists believe that the destruction of the ozone layer is a serious problem for people everywhere. Global warming could change weather patterns around the world. Farmers and ranchers(牧場主) could find it more and more difficult to produce enough food for the earth’s people. If more of the sun’s dangerous rays reached the earth, there also could be an increase in skin cancers. Some skin cancers might cause people to die. Although some scientists do not believe there is a serious danger, obviously no one wants to take any chance on such a possibility.
Can scientists repair the hole in the ozone layer? They really don’t know the answer to that question. Can people do anything to save the ozone layer that the earth still has? Scientists stress the need to limit the use of spray cans and other items that contain the dangerous gases. This will not be an easy task. People all over the world use these items. Solving the problem certainly will require commitment and cooperation from everyone.
小題1:The ozone layer exists to _____.
A.warm the earth to a proper level for life
B.protect the earth from dangerous sun rays
C.make all life on the earth in a dangerous situation
D.prevent human beings from being harmed from the earth
小題2:Which of the following statements is TRUE according to the passage?
A.Scientists aren’t sure what has destroyed part of the ozone layer.
B.Scientists recently have discovered a hole in the Antarctica.
C.Scientists prove that spray cans have destroyed part of the ozone layer.
D.Global warming doesn’t affect weather patterns around the world.
小題3: The following may do harm to the ozone layer EXCEPT ______.
A.spray cansB.refrigeratorsC.ranchersD.a(chǎn)ir conditioners
小題4: Saving the ozone layer needs everyone’s effort because _____.
A.scientists are badly in need of others’ help
B.items containing dangerous gases should be forbidden
C.scientists can’t afford so much money to take measures
D.people all over the world use items containing dangerous gases
