It is natural that children are curious (好奇的) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
These scientists have already discovered a lot about our world．For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and
nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.According to the passage, which of the following statements is true?

I love it at night. It’s peaceful. And when it cools down I sometimes do some ironing. I don’t really care for it. I work full-time and too busy for most housework. I remember the old woman who taught me to iron. I was about 15 and somehow got a live-in job taking care of a woman who had been an able-bodied, healthy woman until the accident that caused her to be paralyzed（瘫痪）.
The woman had an electric wheelchair. She could move her head and arms but not her hands or fingers. She had this clamp（夹子）attached to her arm and I’d have to open it and put a cup or a pencil in it and then she could move it. She would tell me how to do things. She would instruct me in great detail on the correct way to do things. Her home was perfect and beautiful. She would follow me around in her electric wheelchair to make sure I did everything exactly right. I’m sure she had been a perfect homemaker. She would have me fold everything, including socks and pillow cases. I would complain silently and wish terrible things on her. She taught me the right way to make the bed and tuck （塞）the corners. I know sometimes she’d get frustrated and impatient with me. I knew she wanted to grab it and do it herself. But she never yelled or scolded. Only insisted I do it right. I didn’t like it much, but I did it.
Today I can iron pretty well. I know where to start on a shirt, the right way to do the collar and sleeves. Now that I think about it, I don’t think she is an old lady. I think she might have been about my age now. Anyway, when I iron, I think of her and silently thank her for all the things I learned.

Special Bridges Help Animals Cross the Road
—Reported by Sheila Carrick
Why did the chicken cross the road? To get to the other side.
Most people know this joke. But recently, some people have been much more worried about how the grizzly bear (灰熊) and mountain lion can cross the road.
“Millions of animals die each year on U.S. roads,” the Federal Highway Administration reports. In fact, only about 80 ocelots, an endangered wild cat, exist in the U.S. today. The main reason? Roadkill.
“Ecopassages ” may help animals cross the road without being hit by cars. They are paths both over and under roads. “These ecopassages can be extremely useful, so that wildlife can avoid road accidents,” said Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the ecopassages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an ecopassage that went under a highway. This showed that the lions used the passage.
Builders of ecopassages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on. Animals as different as salamanders (火蜥蜴) and grizzly bears are using the bridges and underpasses.
The next time you visit a park or drive through an area with a lot of wildlife, look around. You might see an animal overpass!The writer uses the example of “ocelots” to show that _______.
| A．wild animals have become more dangerous |
| B．the driving conditions have improved greatly |
| C．the measure for protecting wildlife fails to work |
| D．an increasing number of animals are killed in road accidents |
From the news story, we know an ecopassage is ________.
| A．an underground path for cars |
| B．a fence built for the safety of the area |
| C．a bridge for animals to get over a river |
| D．a path for animals to cross the road |
When the writer says that animals seem “to be catching on”, he means ________.
| A．animals begin to realize the dangers on the road |
| B．animals begin to learn to use ecopassages |
| C．animals are crossing the road in groups |
| D．animals are increasing in number |
The writer asks visitors and drivers to look around when traveling because ________.
| A．wild animals may attack cars |
| B．wild animals may block the road |
| C．they may see wild animals in the park |
| D．they may see wild animals on ecopassages |
With eco-tourism on the rise, eco-hotels are fast becoming the darling of the travel industry. These days, however, staying at an eco-hotel doesn’t necessarily mean vacationing in a tree house in the Costa Rican jungle, although that is certainly a choice.
The majority of eco-hotels fall into several categories: hotels and resorts that conserve ecologically important habitats; “green” hotels that reduce, recycle, minimize waste, and protect water; sustainable hotels that harvest food from gardens on the hotel property or get part or all of their power from renewable energy; hotels that encourage community involvement such as guests taking part in trail clearing; and hotels that offer some form of environmental education to their guests.
As such, eco-hotels are a various group. Stylish urban hotels like the Willard Inter-Continental Washington focus on energy conservation whereas the Rosario Resort & Spa on Orcas Island in Washington State offers a wildly popular “green” vacation package where guests can “take a hike, clear a trail”.
No matter what you call them, eco-hotel, eco-lodge, eco-resort, or green hotel, they’re all part of the “greening” of the tourism industry.
Part of what drives this greening of the hotel industry is no doubt competition. Going green is another way to distinguish a hotel from the mass of other excellent hotels that consumers have to choose from. But for many hotels, it’s also part of their philosophy. With the concept of “going green” firmly rooted in consumers’ minds, eco-hotels have taken it to the next level, and whether or not money is the driving factor behind the greening of the hotel industry doesn’t matter so much as it’s good for the planet.According to the passage, which of the following can match the idea of eco-hotel?
| A．It is comfortable and fashionable. | B．It uses renewable energy. |
| C．It has walls of glass. | D．It is home to endangered species. |
From the passage, we know the Rosario Resort & Spa is a kind of hotel that _______.
| A．encourages its guests to participate in its greening activities |
| B．harvests food from its own garden |
| C．has courses on the environment for its guests |
| D．protects important habitats |
From the last paragraph, we can infer that _______.
| A．money is the driving force behind eco-hotels |
| B．the hotel industry cares more about money than the environment |
| C．eco-hotels teach their guests the philosophy of eco-hotels |
| D．eco-hotels have no advantages in competing for guests |
Facebook means never having to say goodbye. The social media website has earned a reputation for reconnecting old friends. Last week, a guy whom I hadn’t seen since my bachelor party five years ago sent me a friend request. I accepted and waited for “Easy E” to send me a greeting of some kind. He had sought me out, after all.
I learned from his profile that he was in a relationship and had a son. However, I’m pretty sure we won’t ever write wall-to-wall, let alone e-mail each other. But he’ll remain a friend of online until one of us makes a point of removing the other from his official list.
My pool of friends consists of family members, college buddies, co-workers from past and present, and friends of friends. There are 35 in all. If I spent some time uploading old e-mail addresses, I’m confident that I could increase my friend count actually.
A person could make a mission out of reconnecting with childhood friends, former classmates, distant cousins, and those one would like to get to know better. And some people can even handle hundreds of on-screen relationships, keeping up with the daily happenings of their small army of companions. After all, there are worse fates than having too many friends.
Thanks to e-mail, the inability to schedule face-to-face meetings no longer means a friendship must come to a close. But even with e-mail, people will lose touch if one or both parties stop writing back. That’s normal. People move from school to school, job to job, city to city. You never have to feel guilty for breaking away.
Every day, the masterminds of Web 2.0 find new ways of making human communication easier. However, convenience can be a walking stick. Some things shouldn’t be simplified. When it comes to friendship, there can be no shortcuts.According to Paragraph 1, the website is famous because .
| A．it has an interesting name of “Facebook” |
| B．it can send people a greeting of some kind |
| C．it helps people get in touch with old friends |
| D．it reminds people of events in the past |
From the second paragraph we can learn that the writer .
| A．would write to the friend quite often |
| B．did get some information about the friend |
| C．asked the friend to e-mail him |
| D．would keep in touch with the friend forever |
Which of the following statements is NOT true?
| A．The author communicates with all the 35 friends by e-mails. |
| B．There are 35 people in the author’s list of friends right now. |
| C．The list of 35 friends doesn’t include the old e-mail addresses. |
| D．It is not difficult for the author to increase his friend count. |
What does the writer mean by saying “However, convenience can be a walking stick”？
| A．The masterminds of Web 2.0 also sell walking sticks online. |
| B．Taking a walking stick is a new way of making friends online. |
| C．Convenience is dangerous for human communication. |
| D．Convenience is not really good for human communication. |
Over the past decade, cheating—an act of academic dishonesty—has become more and more common.
The latest statistics shows more than two thirds of high school students admitted cheating on an exam last year, and—even more surprising—often the best students cheat to get to the top of their class—and they don’t think it is wrong. It’s not a big deal. Everybody is doing it.
It is a big deal! Cheating is basically wrong and must be punished.
If students easily get away with it, they might be encouraged to do it again. They won’t realize that this—in the broadest sense—is an attack on our society, which is based on values like honesty and fairness. The present spreading of cheating indicates a loss of those values and cannot be tolerated. An appropriate punishment for cheating incidents would make students aware of their misbehavior.
If no one were punished for cheating, who would ever study for an exam? Tons of papers would be lifted from websites, writing crib sheets would be more important than reviewing the subjects, and highly sophisticated cheating arts would be invented. Knowledge would only exist on the Internet and on cleverly created cheat sheets, but not in the minds of the students—a rather bad precondition to enrich our society wisely and intelligently.
Students have to learn that they have to learn. Only doing what’s right will bring them a feeling of pride and accomplishment and create self-confidence—the building blocks for a successful and satisfying life and a society that keeps its values.What is more surprising is that .
| A．cheating is very common in schools |
| B．over 2/3 of the students cheat last year |
| C．even the best students cheat on exams |
| D．teachers are not aware of the problems |
How do they make the students realize their misbehavior?
| A．By letting them getting away with it. |
| B．By telling them what is right. |
| C．By catching them on the spot. |
| D．By giving them some punishment. |
How can students create self-confidence?
| A．By knowing they have to learn. |
| B．By doing what is right. |
| C．By learning the right things. |
| D．By being punished when cheating. |
What does the underlined word “lifted” mean?
| A．taken | B．removed | C．copied | D．written |
