When I was about 12, I had an enemy, a girl who liked to point out my shortcomings. Week by week her list grew: I was very thin, I wasn’t a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.
He listened to me quietly, and then he asked. “Are the things she says true or not? Janet, didn’t you ever wonder what you’re really like? Well, you now have that girl’s opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”
I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn’t change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I got a fairly clear picture of myself.
I brought the list back to Daddy. He refused to take it. “That’s just for you,” he said. “You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feel hurt. When something said about you is true, you’ll find it will be of help to you. Don’t shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.”
Daddy’s advice has returned to me at many important moments. In my life, I’ve never had a better piece of advice. Which do you think would be the best title for this passage?

| C．I was having more and more shortcomings as time went on. |
| D．Week by week, my shortcomings grew more serious. |

Susan Sontage（1933—2004）was one of the most noticeable figures in the world of literature. For more than 40 years she made it morally necessary to know everything---to read every book worth reading ,to see every movie worth seeing .When she was still in her early 30s, publishing essays in such important magazines as Partisan Review, she appeared as the symbol of American culture life ,trying hard to follow every new development in literature, film and art .With great effort and serious judgement. Sontage walked at the latest edges of world culture.
Seriousness was one of Sontage’s lifelong watchwords(格言), but at a time when the barriers between the well-educated and the poor-educated were obvious, she argued for a true openness to the pleasure of pop culture. In “Notes Camp”, the 1964 essay that first made her name ,she explained what was then a little-known set of difficult understandings, through which she could not have been more famous .“Notes on Camp”. she wrote, represents “a victory of ‘form’ over ‘content’, ‘beauty’ over ‘morals’”.
By conviction（信念）she was a sensualist（感觉论者）, but by nature she was a moralist （伦理学者）,and in the works she published in the 1970s and 1980s , it was the latter side of her that came forward. In illness as Metaphor —published in 1978, after she suffered cancer—she argued against the idea that cancer was somehow a special problem of repressed personalities（被压抑的性格）, a concept that effectively blamed the victim for the disease. In fact , re-examining old positions was her life long habit.
In America, her story of a 19th century Polish actress who set up a perfect society in California, won the National Book Award in 2000. But it was as a tireless all-purpose cultural view that she made her lasting fame. “Sometimes,” she once said，“I feel that, in the end, all I am really defending is the idea of seriousness, of true seriousness.” And in the end, she made us take it seriously too.The underlined sentence in paragraph 1 means Sontag_________.

Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.
The ridge（脊状）structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.
Finger-prints can be made very easily with printer's ink. They can be recorded easily. With special methods, identification can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident.
When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to "develop" them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.Scientists and experts have proved that the pattern of a human being's finger skin__ ___
| A．is similar to his mother's |
| B．is valuable to himself only |
| C．is like that of others with the same type of blood. |
| D．is different from that of all others |
If your fingers are wounded by knife, fire or other means, the structure of skin will____.
| A．be changed partly |
| B．be replaced by a different one |
| C．be the same when the wound is recovered |
| D．become ugly |
Some criminals remove their own finger-prints by ____.
| A．using printer's ink |
| B．injuring the inner skin |
| C．damaging the outer skin |
| D．damaging the color |
Finger-prints have often been used as a method of solving criminal case because it_____.
| A．is complicated but reliable |
| B．is simple and not expensive |
| C．is expensive but easy to do |
| D．can bring a lot of money |
It is ________for a criminal to deny his crime when finger-prints are used to identify him.
| A．worth trying | B．successful | C．useful | D．useless |
Could we "terraform" Mars—that is, change its frozen, thinaired surface into something more friendly and Earthlike? Should we? The first question has a clear answer: Yes, we probably could. Spacecraft, including the ones now exploring Mars, have found evidence that it was warm in its youth，with rivers flowing into vast seas. And right here on Earth, we've learned how to warm a planet: just add greenhouse gases to its atmosphere. Much of the CO2 that once warmed Mars is probably still there，in frozen dirt and polar ice caps, and so is the water.
Most of the work in terraforming，says NASA scientist Chris Mackay, would be done by life itself. "You don't build Mars," Mackay says. "You just warm it up and throw some seeds." Powerful greenhouse gases could be produced from elements in dirt and air on Mars and blown into the atmosphere； by warming the planet, they would release the frozen CO2 , which would quicken the warming and increase atmospheric pressure to the point where liquid water could flow. Meanwhile, says botanist James Graham of the University of Wisconsin, human settlers could seed the red rock with a succession (系列) of ecosystems, first bacteria and lichens (地衣)，which survive in Antarctica, later mosses (苔藓)，and after one thousand years or so，redwoods. Getting breathable oxygen levels out of those forests，though，could take thousands of years.
However, Mars is in no immediate danger. Some space scientists recently recommended going to the moon or an asteroid (小行星)first，and pointed out the space agency lacks the funds to go anywhere. It didn't estimate the cost of gardening a dead planet. What is the most essential to make Mars fit for living?
| A．Turn ice into flowing water. |
| B．Clean the dirty atmosphere. |
| C．Make the atmosphere more suitable. |
| D．Go to the moon or an asteroid first. |
What does the author think of the idea of terraforming Mars?
| A．We could do it. | B．We couldn't do it. |
| C．We should do it. | D．We shouldn't do it. |
In the botanist's opinion, man needs to ______ .
| A．enable Mars to clean its atmosphere |
| B．build a greenhouse on Mars |
| C．send some people to settle on Mars |
| D．cultivate ecosystems from lower to higher life form |
What is the best title for the passage?
| A．Making Mars the New Earth. |
| B．A Good Way to Change the Universe. |
| C．Humans' Great Power. |
| D．Terrible Science and Technology. |
We already know the fastest, least expensive way to slow climate change ： Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.
Not long ago， my wife，PJ， and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is heating up even faster than predicted only a few years ago，and that the consequences could be severe if we don't keep reducing emissions (排放)of carbon dioxide ( CO2) and other greenhouse gases that are trapping heat in our atmosphere.
We decided to try an experiment. For one month we recorded our personal emissions of CO2. We wanted to see how much we could cut back, so we went on a strict diet. The average US household produces about 150 pounds of CO2 a day by doing commonplace things like turning on air conditioning or driving cars. That's more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce?
For an answer, I checked with Tim Flannery, author of The Weather Makers： How Man Is Changing the Climate and What It Means for Life on Earth. In his book， he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting of the ice sheets in Greenland or West Antarctica. "To stay below that point, we need to reduce CO2 emissions by 80 percent," he said.
Good advice, I thought. I'd opened our bedroom windows to let in the wind. We'd gotten so used to keeping our air conditioning going around the clock. I'd almost forgotten the windows even opened. We should not let this happen again. It's time for us to change our habits if necessary. Why did the author and his wife try a new diet?
| A．To take special kinds of food. |
| B．To respond to climate change. |
| C．To lose weight. |
| D．To improve their health. |
The underlined words "tipping points" most probably refer to ______ .
| A．freezing points | B．burning points |
| C．melting points | D．boiling points |
It can be inferred from the passage that ______ .
| A．it is necessary to keep the air conditioning on all the time |
| B．it seems possible for every household to cut emissions of CO2 |
| C．the average US household produces about 3,000 pounds of CO2 a month |
| D．the average European household produces about 1, 000 pounds of CO2 a month |
Which of the following would be the best title for this passage?
| A．Saving Energy Starts at Home |
| B．Changing Our Habits Begins at Work |
| C．Changing Climate Sounds Reasonable |
| D．Reducing Emissions of CO2 Proves Difficult |
Let These Plants Swat the Bugs for You Some plants get so hungry that they eat flies，spiders, and even small frogs. What's more amazing is that these plants occur naturally (in special environments) in every state. In fact, they're found on every continent except Antarctica.
You've probably seen a Venus' flytrap. It's often sold in museum gift stores, department stores, and even supermarkets. A small plant，it grows 6 to 8 inches tall in a container. At the end of its stalks (are specially modified leaves that act like traps. Inside each trap is a lining of tiny trigger (触发)hairs. When an insect lands on them, the trap suddenly shut. Over the course of a week or so, the plant feeds on its catch.
The Venus' flytrap is just one of more than 500 species of meat-eating plants， says Barry Meyers-Rice ， the editor of the International Carnivorous Plant Society's Newsletter. Note： Despite any science-fiction stories (科幻小说)you might have read, no meat-eating plant does any danger to humans.
Dr. Meyers-Rice says a plant is meat-eating, only if it does all four of the following："attract, kill, digest, and absorb" some form of insect, including flies, butterflies, and moths. Meat-eating plants look and act like other green plants—well, most of the time.
All green plants make sugar through a process called photosynthesis (光合作用). Plants use the sugar to make food. What makes "meat-eating" plants different is their bug-catching leaves. They need insects for one reason ： nitrogen (氮). Nitrogen is a nutrient that they can't obtain any other way. Why?
Almost all green plants on our planet get nitrogen from the soil. "Meat-eating" plants can't. They live in places where nutrients are hard or almost impossible to get from the soil because of its acidity (酸度). So they've come to rely on getting nitrogen from insects and small animals. In fact, nutrient-rich soil is poisonous to "meat-eating" plants. Never fertilize (施肥)them! But don't worry, either, if they never seem to catch any insects. They can survive, but they'll grow very slowly. Venus flytrap ______.
| A．is a small plant which grows in a container |
| B．is a kind of plant which gets hungry easily |
| C．can attract, kill， digest and absorb some form of insects |
| D．grows 6—8 inches tall |
From the passage, we know ______.
| A．"meat-eating" plants are found on every continent |
| B．all green plants get nitrogen from the soil |
| C．bug-catching leaves make "meat-eating" different from other plants |
| D．some "meat-eating" plants in the rainforest do danger to humans |
"Meat-eating" plants grow very slowly, ______.
| A．so you'd better fertilize them |
| B．probably because the source of nitrogen is cut off |
| C．simply because they can't absorb nitrogen from the soil |
| D．and then they will die slowly |
Which of the following is true?
| A．"Meat-eating" plants look and act like other green plants. |
| B．No insects, no "meat-eating" plants. |
| C．The reason why Venus flytrap needs flies is that it needs to get nutrient from them. |
| D．Green plants make sugar at night. |
