Looking back on my childhood, I am convinced that naturalists are born and not made. Although we were brought up in the same way, my brothers and sisters soon abandoned their pressed flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do mental math.
Before World War I we spent out summer holidays in Hungary. I have only the dim(模糊的)memory of the house we lived in, of my room and my toys, Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a crystal clear memory of dogs, the farm animals, the local birds and above all, the insects.
I am a naturalist, not a scientist. I have a strong love of the natural world, and my enthusiasm has led me into various investigations. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries.Then something happens that brings these observations together in my conscious mind. Suddenly you fancy you see the answer to the riddle. Because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some may light honor, with the title of scientific research.
But curiosity, a keen eye ,a good memory and enjoyment of the animal and plant world do not make a scientist: one of the outstanding and essential qualities required is self-discipline, a quality I lack, A scientist can be made a naturalist. If you can combine the two, you get the best of both worlds.According to the author, a born naturalist should first of all be

The Healthy Habits Survey（调查）shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.
1.How many times did you brush your teeth yesterday?
·Finding：A full 33% of seniors brush their teeth only once a day.
·Step：Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.
2.How many times did you wash your hands or bathe yesterday?
·Finding：Seniors, on average, bathe fewer than 3 days a week. And nearly 30%wash their hands only 4 times a day-half of the number doctors recommend.
·Step：We touch our faces around 3,000 times a day-often inviting germs（病菌）to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.
3. How often do you think about fighting germs?
·Finding：Seniors are not fighting germs as well as they should.

Using too much water or throwing rubbish into our rivers are clear ways that humans can
Put our water supply in danger, but we also affect our water supply in less obvious ways.
You may wonder how paving(铺砌) a road can lead to less useable fresh water . A major
Part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺). Driver climates are of course more likely to have droughts(干旱) than areas with more rainfall ,but in any case, good management can help to make sure there is enough water to meet our basic needs .
Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5tons of water a day! This shows how much we depend on water to live ,but there’s a lot we can do to lower the number .
You can take steps to save water in your home .To start with ,use the same glass for your drinking water all day .Wash it only once a day .Run your dishwasher (洗碗机)only when it is full。Help your parents fix any leaks in your home . You can even help to keep our water supply clean by recycling batteries instead of throwing them away. Which of the following is most likely to lead to less groundwater ?
| A．Using river water . |
| B．Throwing batteries away . |
| C．paving parking lots . |
| D．Throwing rubbish into lakes . |
What can be inferred from the text ?
| A．All water shortages are due to human behavior . |
| B．It takes a lot of effort to meet our water needs . |
| C．There is much we can do to reduce family size . |
| D．The average family in America makes proper use of water . |
The last paragraph is intended to .
| A．show us how to fix leaks at home |
| B．tell us how to run a dishwasher |
| C．prove what drinking glass is best for us |
| D．suggest what we do to save water at home |
The text is mainly about .
| A．Why paving roads reduces our water |
| B．how much we depend on water to live |
| C．why droughts occur more in dry climates |
| D．how human activity affects our water supply |
Easter(复活节 ) is still a great day for worship, randy in baskets and running around the yard finding eggs, but every year it gets quite a bit worse for bunnies.
And no, not because the kids like to pull their ears. The culprit is climate change, and some researchers found that rising temperatures arc having harmful effects on at least five species of rabbit in the US.
Take the Lower Keys March rabbit, for instance. An endangered species that lives in the Lower Florida Keys, this species of cottontail is a great swimmer — it lives on the islands! — but it is already severely affected by development and now by rising levels. According to the Center for Biological Diversity, an ocean level rise of only 0. 6 meters will send these guys jumping to higher ground and a 0.9-meter rise would wipe out their habitat (栖息地) completely.
The snowshoe hare, on the other hand, has a color issue. Most of these rabbits change their fur color from white in the wintertime to brown in the summer, each designed to give them better cover from predators（捕食者）. As the number of days with snow decreases all across the country, however, more and more bunnies arc being left in white fur during brown dirt days of both fall and spring, making them an easier mark for predators. Researchers know that the color change is controlled by the number of hours of sunlight, but whether the rabbit will be able to adapt quick enough to survive is a big question. The National Wildlife Federation has reported that hunters have noticed their numbers are already markedly down.
American pikas or rock rabbits, a relative of rabbits and hares, might be the firs' of these species to go extinct due to climate change. About 7-8 inches long, pikas live high in the cool, damp mountains west of the Rocky Mountains. As global temperatures rise, they would naturally migrate (迁徙) to higher ground — but they already occupy the mountaintops. They can't go any higher. The National Wildlife Federation reports that they might not be able to stand the new temperatures as their habitat beats up.
The volcano rabbit has the same problem. These rabbits live on the slopes of volcanoes in Mexico, and recent studies have shown that the lower range of their habitat has already shifted upward about 700 meters, but there are not suitable plants for them to move higher, so they are stuck in the middle. Scientists are concerned about their populations.
Native to the US, pygmy rabbits weigh less than 1 pound and live in the American West. They are believed to be the smallest rabbits in the world. Their habitats have been destroyed by development. Several populations, such as the Columbia Basin pygmy, almost went extinct and were saved by zoo breeding programs. Pygmy rabbits also rely on winter cover by digging tunnels through the snow to escape predators, but lesser snowfall is leaving them exposed.
All of this gives new meaning to dressing up in a giant bunny costume this Easter. The word "culprit" ( Paragraph 2) is closest in meaning to______.
| A．criminal |
| B．judge |
| C．victim |
| D．producer |
According to the passage, some rabbits can now be easily Uncovered by predators because they_______
| A．are exposed lo more skillful hunters |
| B．have moved to habitats with fewer plants |
| C．haven't adapted themselves to climate change |
| D．can't change their fur color into white in the fall and the spring |
The problem faced by volcano rabbets and rock rabbits is that________.
A. both are affected by 1ess snow
B. both are affected by rising sea levels
C neither can find enough food
D. neither can migrate to higher places
Since 1984, Philadelphia has been cleaning up its act. One by one, graffiti-covered walls are being changed into outdoor art. So far, more than 1,800 murals（壁画）have been painted. Philadelphia now has more murals than any other American city.
The walls that were once ugly with graffiti（涂鸦）are now covered with beautiful pictures of historical heroes and modern art, thanks to the Mural Arts Program (MAP). Its work makes schools and public places attractive, and its citizens very proud. The program began as part of Philadelphia‟s Anti-Graffiti Network. Jane Golden is the MAP‟s artistic director. “When people ask me what our program is about,” she says, “I answer them with one word: hope.” Each year, the MAP offers youth art programs and workshops. Some one-time graffiti writers even help paint MAP murals.
The MAP‟s work, says Golden, is all about developing a sense of community（社区）．When a neighborhood requests a mural, the MAP works with the people there to develop a message. Some messages have been “Safe Streets,” “Love and Care,” and “Peace Walk.”
The MAP receives up to 50 requests for murals each week. Last year, the workers painted 140 murals.
“The making of a mural enters people‟s collective memory as an extraordinary, pleasant moment in neighborhood history,” says Golden, who began as a muralist in Los Angeles. What can be the best title for the text?

What is the Mural Arts Program in Philadelphia aimed at?
| A．Helping the young find jobs. |
| B．Protecting the neighborhood. |

By having discussions with people in the community.
B. By seeking advice from the city government.
C. By learning from the young graffiti writers.
D. By studying the history of the city. Which of the following words best describes the work of the MAP?

Some people believe that a Robin Hood is at work, others that a wealthy person simply wants to distribute his or her fortune before dying. But the donator who started sending envelopes with cash to deserving causes，accompanied by an article from the local paper, has made a northern German city believe in fairytales (童话）•
The first envelope was sent to a victim support group. It contained €10,000 with a cutting from the Braunschtveiger Zeitung about how the group supported a woman who was robbed of her handbag； similar plain white anonymous (匿名）envelopes, each containing €10,000, then arrived at a kindergarten and a church.
The envelopes keep coming, and so far at least €190,000 has been distributed. Last month, one of them was sent to the newspaper ’s own office. It came after a story it published about Tom, a 14-year-old boy who was severely disabled in a swimming accident. The receptionist at the Braunschweiger Zeitung opened an anonymous white envelope to find 20 notes of €500 inside , with a copy of the article. The name of the family was underlined.
"I was driving when I heard the news,” Claudia Neumann, the boy s mother, told DerSpiegel magazine. “I had to park on the side of the road； I was speechless. ”
The money will be used to make the entrance to their house wheelchair-accessible .and for a course of treatment that their insurance company refused to pay for.
“For someone to act so selflessly, for this to happen in such a society in which everyone thinks of himself, was astonishing," Mrs. Neumann said. Her family wonder whether the donator is a Robin Hood character, taking from banks to give to the needy.
Henning Noske, the editor of the Braunschweiger Zeitung, said： “Maybe it is an old person who is about to die. We just do not know. ” However, he has told his reporters not to look for the city’s hero, for fear that discovery may stop the donations.The Braunschweiger Zeitung is the name of .

| A．The donation amounted to €190,000. |
| B．The donation was sent directly to his house. |

It can be inferred from the passage that .
| A．the donator is a rich old man |
| B．the donation will continue to come |
| C．the donation comes from the newspaper |
| D．the donator will soon be found out |
What would be the best title for the passage?
| A．Money Is Raised by the Newspaper |
| B．Newspaper Distributes Money to |
