In the eyes of dog lovers, the dog is man’s best friend. But for much wildlife, loose dogs may be a dangerous enemy, according to a study by a biologist from Utah State University in the US.
Based on much existing research and their own case studies, Julie Young of Utah State University and four other scientists conclude that loose dogs may represent a huge danger to wildlife, especially endangered species, by hunting down or worrying them and by spreading diseases. They also found that dogs, their worldwide numbers around 500 million, can cause more damage to wildlife and livestock(牲畜) than wolves and other enemies of these animals.
Young gave examples from the US state of Idaho, where research showed the presence of dogs reducing some deer populations. On the Navajo American Indians’ reservation in northeastern Arizona, packs of loose dogs are chasing livestock. They have killed populations of small animals such as rabbits and act as a disease carrier for rabies(狂犬病) among people and other animals, she said. Loose dogs also were to blame for distemper outbreak leading to a die-off of endangered black-footed ferrets in northwestern Wyoming in the 1980s.
The phenomenon is not just limited to US; it’s a global problen. Julie Young once studied three endangered species in central Asia: wild sheep, gazelles and antelope. The rate of injury and death to these animals by loose dogs was very high. In another case, Young found that dogs, not wolves, as originally suspected, were responsible for a large number of livestock killings in the mountainous Basque country between Spain and France.
Authors of the new study said the problem is likely to worsen as communities expand. Then how to deal with it?
Indeed, in many countries, leash(拴狗的皮帶) laws permit punishment of dog owners whose pets chase wildlife. But lawbreakers are rarely punished because the police lack both people and money.
Young has low-cost solutions to the problem for dog lovers, though. They include public dog-training programs and vaccinating (預(yù)防接種) dogs against rabies and other illnesses.
小題1:. What is the main point of Julie Young’s study?
A．Many species are endangered because they are killed by loose dogs.
B．Wild dogs are immune to many diseases.
C．Wolves are still the greatest enemy of livestock.
D．Loose dogs pose a great danger to wildlife.
小題2:. Which of the following statements about loose dogs is TRUE according to the research?
A．There are around 500 million loose dogs around the world.
B．The black-footed ferrets in northwestern Wyoming were once the main food source of local loose dogs.
C．The problem caused by loose dogs is the most serious in the US.
D．People used to think that wolves, rather than loose dogs killed livestock in the Basque country.
小題3:. Which of the following is among Julie Young’s solutions to the trouble caused by loose dogs?
A．More strict leash laws
B．Public dog-training programs.
C．Vaccinating people against rabies and other illnesses.
D．More support from the police.
小題4:. What is the main point of the article?
A．A global disaster caused by loose dogs.
B．What makes the dog man’s greatest friend.
C．The problem of loose dogs and the possible solutions.
D．The danger of the increasing numbers of dogs.

The 47-year-old singer talks about the new album Symphony（交響樂(lè)） that came out of a “very dark time”, including her decision to give up trying to have children. “People have suggested I could adopt,” Brightman says. “But work is central to my life now. And so I am going to put it to one side. After a while not having children becomes the norm and perhaps that might sound alarming, to parents especially, but I have never known anything different. I’m not hurt by not having children. My life and career are incredibly rich.”
Talking about growing up in a large family in Berkhamsted (father a property developer who later committed suicide), she says: “I was gifted as a child, and very musical. I seemed to be good at anything to do with the arts. At 5，I understood the music I was dancing to and had an eye for costume.” She first appeared in a West End musical at 11 and hated boarding school.
Brightman led the saucy dance troupe（辣妹三人舞） Hot Gossip and had her first hit with I Lost My Heart to a Starship Trooper in 1978. At 18 she married a music manager called Andrew Graham Stewart. “I was probably in love but I can’t remember. Girls change such a lot between 18 and 22. It didn’t really work out.” In 1981 she was spotted by Lloyd Webber. She became his leading lady in Song and Dance, Requiem and Phantom of the Opera. They married in 1984.
Brightman says she felt hostility(敵意) “from the beginning. I haven’t tried to understand it. I’ve done very well everywhere else, especially the US, where I now live, I just accept it for what it is. The more you are away from Britain, the more you appreciate it. But I don’t miss it, although I miss my family. Our profession can be uncomfortable but I enjoy what I do. I get on with it.”

小題4:The underlined word in the fourth paragraph probably means _____.

Americans use many expressions with the word “dog”. People in the United States love their dogs and treat them well. They take their dogs for walks, let them play outside and give them good food and medical care. However, dogs without owners to care for lead a different kind of life. The expression “to lead a dog’s life” describes a person who has an unhappy existence.
Some people say we live in a dog-eat-dog world. That means many people are competing for the same things, like good jobs. They say that to be successful, a person has to work like a dog. This means they have to work very, very hard. Such hard work can make people dog-tired. And, the situation would be even worse if they became sick as a dog.
Still, people say every dog has its day. This means that every person enjoys a successful period during his or her life. To be successful, people often have to learn new skills. Yet, some people say that you can never teach an old dog new tricks. They believe that older people do not like to learn new things and will not change the way they do things.
People who are unkind or uncaring can be described as meaner than a junkyard dog. Junkyard dogs live in places where people throw away things they do not want. Mean dogs are often used to guard this property. They bark or attack people who try to enter the property. However, sometimes a person who appears to be mean and threatening is really not so bad. We say his bark is worse than his bite.
Doghouse provide shelter but they can be cold and lonely in the winter. Husbands and wives use this doghouse term when they are angry at each other. For example, a woman might get angry at her husband for coming home late or forgetting their wedding anniversary. She might tell him that he is in the doghouse. However, the husband may decide that it is best to leave things alone and not create more problems. He might decide to let sleeping dogs lie.
Dog expressions also are used to describe the weather. The dog days of summer are the hottest days of the year. A rainstorm may cool the weather. But we do not want it to rain too hard. We do not want it to rain cats and dogs.
小題1:The passage tells us something about________.
A．dogs and their lifeB．the expressions that describe dogs
C．the meaning of expressions with the word “dog”D．the structures of dog expressions
小題2: By saying _______, we compare people to dogs in bad ways.
A．“meaner than a junkyard dog”B．“to work like a dog”
C．“teach an old dog new tricks”D．“as sick as a dog”
小題3:By saying ________, we mean every person enjoys a successful period in life.
A．“he lives in a dog-eat-dog world”B．“he leads a dog’s life”
C．“he is in the doghouse”D．“every dog has its day”
小題4: If we advise the others to leave things alone and not create more problems, we say_______.
A．“become sick as a dog”B．“rain cats and dogs”
C．“l(fā)et sleeping dogs lie”D．“stay in the doghouse”
小題5: It has been really hot these days, as _______.

There was a gardener who looked after his garden with great care. To water his flowers, he used two buckers. One was a shiny and new bucket. The other was a very old and dilapidated one, which had seen many years of service, but was now past its best.
Every morning, the gardener would fill up the two buckets. Then he would carry them along the path, one on each side, to the flowerbeds. The new bucket was very proud of itself. It could carry a full bucket of water without a single drop spilled (溢出). The old bucket felt very ashamed because of its holes: before it reached the flowerbeds, much water had leaked along the path.
Sometimes the new bucket would say, “See how capable I am! How good it is that the gardener has me to water the flowers every day! I don't know why he still bothers with you. What a waste of space you are!”
And all that the old bucket could say was, “I know I’m not very useful, but I can only do my best. I’m happy that the gardener still finds a little bit of use in me, at least.”
One day, the gardener heard that kind or conversation. After watering the flowers as usual, he said, “You both have done your work very well. Now I am going to carry you back. I want you to look carefully along the path.”
Then the two buckets did so. All along the path, they noticed, on the side where the new bucket was carried, there was just bare (光禿禿的)earth; on the other side where the old bucket was carried, there was a joyous row of wild flowers, leading all the way to the garden.
小題1:What does the underlined word “dilapidated” probably mean?
A．DirtyB．Dark
C．Worn-outD．Plain-looking.
小題2:What was the old bucket ashamed of?
A．His past.B．His aging.
C．His manner.D．His leaking.
小題3:The new bucket made conversations with the old one mainly to         
A．laugh at the old one
B．take pity on the old one
C．show off its beautiful looks
D．praise the gardener’s kindness
小題4:Why was the old bucket still kept by the gardener?
A．Because it was used to keep a balance
B．Because it stayed in its best condition
C．Because it was taken as a treasure
D．Because it had its own function

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 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.
“Eco-passages” may help animals cross the road without being hit by cars. They are paths both over and under roads. “These eco-passages 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 eco-passages?  The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an eco-passage that went under a highway.  This showed that the lions used the passage.
Builders of eco-passages 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!
小題1: The writer uses the example of “ocelots” to show that __________.
A．wild animals have become more dangerous
B．the driving condition has improved greatly
C．a(chǎn)n increasing number of animals are killed in road accidents
D．the measure for protecting wildlife fails to work
小題2:From the story, we know an eco-passage is __________.
A．a(chǎn)n underground path for cars
B．a(chǎn) fence built for the safety of the area
C．a(chǎn) bridge for animals to get over a river
D．a(chǎn) path for animals to cross the road
小題3: When the writer says that “animals seem to be catching on” (Para. 6), he means __________.
A．a(chǎn)nimals begin to realize the dangers on the road
B．a(chǎn)nimals are crossing the road in groups
C．a(chǎn)nimals are increasing in number
D．a(chǎn)nimals begin to learn to use eco-passages
小題4: The writer asks visitors and drivers to look around when traveling because __________.
A．wild animals may attack carsB．they may see wild animals on eco-passages
C．they may see wild animals in the parkD．wild animals may jam the road
小題5: The best title for the passage is __________.
A．Special bridges help animals cross the road
B．Endangered animals increase because of roadkill
C．Animals fail to cross the road
D．Take steps to protect animals in danger

One in five American families will move every year. Moving is one of the most stress-producing events a family has to go through. Experts say it can be harder for children. How do you help your child adjust to the changes?
The Ricardos moved from their old house to a new home. Same family, same dog-but it was harder for 9-year-old Elena. She hated the room, the house and everything. She hated leaving her friends the most.
“ I was so emotional. I mean, saying goodbye to all my friends…..my very close friends, who was my neighbor, made me so sad,” says Elena.
For some children, the emotional stress of moving is not much more different from the emotions when someone has died.
“There’s that sense that, ‘I’ve lost my friends, my friends, my base, my school, my teachers-everything I knew that made me feel safe is all gone now. I have to start over,” says Dr. Tim Jordan.
Starting over is exactly Dr. Tim Jordan’s advice. Make new friends, enter the new school and enter the new neighborhood. And here are some other pieces of advice.
● Explain clearly to the children why the move is necessary.
● Familiarize(使熟悉) the children as much as possible with the new area with maps, photographs or the daily newspaper.
● After the move, got the children to join in activities in the place.
● Help the children keep in touch with friends from the neighborhood before through telephone, letters, e-mail, and personal visits.
小題1:
Which of the following is useful to reduce the children’s stress before the move?
A．Let doctors give children some advice.
B．Try letting children accept the fact of moving.
C．Let children keep in touch with their former friends.
D．Copy the new environment in the old home.
小題2:
What can we know from the passage?
A．Most American children can get used to the changes in moving.
B．Dr. Tim Jordan lost his family, friends, teachers after moving.
C．The emotional stress of moving is the same in some way as that of knowing someone’s death.
D．the Ricardos lost their dogs after moving to their new house.

What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It isn’t the tools a scientist uses but how he uses these tools which make him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigation, how to discover information, is important to everyone. The scientist, however, goes one step further; he must be sure that he has a reasonable answer to his questions and that his answer he gets to many questions is into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There’s no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration(實(shí)證) must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at the theory through mathematics. The accuracy(正確性) of his mathematics was later tested through investigation. Einstein’s ideas were proved to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations(計(jì)算) that may test his investigations
小題1: What makes a scientist according to the passage?
A．The tools he uses.B．His ways of learning
C．The way he uses his toolsD．The various tools he uses
小題2: “…knowing how to investigation, how to discover information, is important to everyone.”
The writer says this to show ___________.
A．the importance of information
B．the difference between scientists and ordinary people.
C．the importance of thinking
D．the difference between carpenters and ordinary people
小題3: A sound scientific theory should be one that _________.
A．works under one set of conditions at one time and also works under the same conditions at other times
B．doesn’t allow any change even under different conditions
C．Can be used many times under different conditions
D．Can be used for many purposes
小題4:What is the main idea of the passage?
A．Scientists are different from ordinary people.
B．The Theory of Relativity.
C．Exactness is the core (核心) of science.
D．Exactness and way of using tools are the keys to making of a scientist.
