Experts say the American state of Hawaii has been invaded (入侵)by a small frog called the coqui (ko--kee). There may be millions of the small frogs in Hawaii. However, they do not belong there. They are normally found in the southeastern United States. The coqui frogs are harming Hawaii’s environment. And the extremely loud noise they make is causing problems for Hawaiian citizens and visitors.
The coqui invaders arrived in Hawaii about ten years ago. They were believed to have been brought in accidentally in shipments of plants from Florida. Their number has sharply increased. They have quickly spread around the Hawaii Islands hidden in plants.
The coqui is a brown frog about five centimeters long. During the day, the frogs hide in wet protected areas, such as under plant leaves. At night, the frogs move onto trees to feed, call to females and mates. The call of the male coqui sounds like. Ko kee! Ko kee!
In the southeastern United States, local people celebrate coqui frogs. But in Hawaii, the foreign frog has been considered as a harmful animal. The coqui frogs are a major danger to Hawaii’s environmental system. The frogs eat thousands of insects (昆蟲)every night. These insects are important for the reproduction of plants. The insects also are important food for Hawaii’s native rare birds. The frogs also are affecting the tourism industry in Hawaii. Increasing numbers of hotels, visitors and local people have been annoyed by the loud calls made by male coqui frogs to female frogs. At night, the noise often makes it difficult for people to sleep.
The frogs do not have any natural enemies in Hawaii to reduce their population size. The warm weather permits them to lay eggs all year long. There are many efforts in Hawaii designed to stop the spread of the coqui. It is a crime to transport ,sell or release(釋放)the frogs there.
The Hawaii Department of Agriculture is trying to find an effective chemical that can be safely used to kill the frogs. For now, the frogs may only be caught by hand. The Hawaii Department of Agriculture says the greatest danger to the economy and environment of the state is from harmful species, like the coqui.
小題1:The statement that can best summarize the main idea of the passage is         .
A.the coqui invaders have seriously affected the tourism industry in Hawaii
B.it is not permitted to transport, sell or release the coqui frogs in Hawaii
C.the coqui invasion has serious effects on the economy and environment in Hawaii

A.by chanceB.a(chǎn)t the request of all the local citizens
C.a(chǎn)s a giftD.a(chǎn)s goods demanded in the local market
小題3:Visitors to Hawaii don’t like the coqui frogs mainly because                 .
A.they are a big danger to the environmental system there
B.the loud noise made by the frogs bother their rest at night
C.they affect the reproduction of the local plants and insects
D.visitors could no longer see the native rare birds because of them
小題4:The two factors leading to the rapid spread of coqui frogs in Hawaii are           .

“Sesame Street” has been called “the longest street in the world.” That is because the television program by that name can now be seen in so many parts of the world. That program became one of American’s exports soon after it went on the air in New York in 1969. ?
In the United States more than six million children watch the program regularly. The viewers include more than half the nation’s pre-school children, from every kind of economic, racial(種族的), and geographical group. ?
Although some educators object to certain elements in the program, parents praise it highly. Many teachers also consider it a great help, though some teachers find that problems arise when first graders who have learned from “Sesame Street” are in the same class with children who have not watched the program. ?
Tests have shown that children from all racial, geographical, and economic backgrounds have benefited from watching it. Those who watch it five times a week learn more than occasional(偶爾的)viewer. In the US the program is shown at different hours during the week in order to increase the number of children who can watch it regularly. ?
The programs all use songs stories, jokes and pictures to give children a basic understanding of numbers, letters and human relationships. But there are some differences. For example, the Spanish program, produced in Mexico City, devotes more time to teaching whole words than to teaching separate letters. ?
Why has “Sesame Street” been so much more successful than other children’s shows? Many reasons have been suggested. People mention the educational theories of its creators, the support by the government and private businesses, and the skillful use of a variety of TV tricks. Perhaps an equally important reason is that mothers watch it along with their children. This is partly because famous adult stars often appear on it. But the best reason for the success of the program may be that it makes every child watching feel able to learn. The child finds himself learning, and he wants to learn more. ?
小題1: “Sesame Street” is actually______. ?
A.a(chǎn) street in the USB.a(chǎn) program for children?
C.a(chǎn) program of teachersD.a(chǎn) program for students?

Animals are more like us than we ever imagined.They feel pain, they experience stress, they show affection, excitement and love.All these findings have been made by scientists in recent years---and such results are beginning to change how we view animals.
Strangely enough, some of this research was sponsored by fast food companies like McDonald’s and KFC.Pressured by animal rights groups , these companies felt they had to fund scientists researching the emotional and mental states of animals.
McDonald’s, for instance, funded studies on pig behavior at Purdue University, Indiana.This research found that pigs seek affection and easily become depressed if left alone or prevented from playing with each other.If they become depressed, they soon become physically ill.Because of this, and other similar studies, the European Union has banned the use of isolating pig stalls from 2010.In Germany, the government is encouraging pig farmers to give each pig 20 seconds of human contact a day, and to provide them with toys to prevent them from fighting
Other scientists have shown that animals think and behave like humans.Koko, the 300-pound gorilla at the Gorilla Foundation in Northern California, for instance, has been taught sign language.Koko can now understand several thousand English words, more than many humans who speak English as a second language.On human IQ tests, she scores between 70 and 95.
Before such experiments, humans thought language skills were absent from the animal kingdom.Other myths are also being overturned, like the belief that animals lack self-awareness.Studies have also shown that animals mourn their dead, and that they play for pleasure.
These striking similarities between animal and human behavior have led some to ask a question: “If you believe in evolution, how can’t you believe that animals have feelings that human  beings have?”
Until recently, scientists believed that animals behaved by instinct and that what appeared to be learned behavior was merely genetically-programmed activity.But as Koko the Gorilla shows, this is not the case.In fact, learning is passed from parent to offspring far more often than not in the animal kingdom.
So what implications does this knowledge have for humans? Because of this, should we ban hunting and animal testing? Should we close zoos? Such questions are being raised by many academics and politicians.Harvard and 25 other American law schools have introduced courses on animal rights.Germany meanwhile, recently guaranteed animal rights in its constitution---the first country to do so.
小題1:McDonald’s and KFC give money to support scientist to do research on animals, because_____
A.they are international big companies.
B.they love animals.
C.they are pressured by animal right groups.
D.they earn a large amount of money and want to do some good deeds.
小題2:The research on pigs at Purdue University shows that______
A.pigs love being alone.
B.pigs easily become physically ill.
C.pigs need affection.
D.pigs don’t like to play with each other.
小題3:Which of the following statements is NOT true?
A.Animals behave by instinct.
B.Animals have self-awareness.
C.Animals have feelings and love.
D.Animals do not have language skills.
小題4:Should we ban hunting and animal testing?

There’s a time to get angry, and it’s best for your child if you do. Let’s say your child hits a playmate with a toy hard enough to make the other child cry. How can you teach your child to feel sorry so he or she won’t do it again? Researchers say the best way for parents to react(反應(yīng))is to show their anger and to let the child know exactly why they are mad.
  Many parents believe that it is best to control their feelings and to wait until they’re calm before scolding their children. But the mother or father who explains reasonably to a child , “Peter was crying because you hit him,” is not likely to attract much attention. Young children need to be scolded immediately, and strongly, before they’ll take criticism (批評)to heart.
  When your young child does something wrong, scold him or her seriously at once. At the same time be sure to tell the child clearly what he or she has done wrong. An angry reaction without an immediate explanation does little good. Forbidding a child to play outside or not allowing him to watch TV as a punishment works well-but only when taken together with an explanation. Make sure your child understands that although his or her wrongdoing has made you angry, you still love him or her. Use simple, direct words such as, “You hurt peter. How would you feel if he hit you? You must never, never hurt people.” If your voice expresses strong feeling clearly, your message will carry enough weight.
小題1:According to researchers, how should parents react when their child did something wrong?
A.Ask the child not to do it again any time.
B.Show the child how angry they are and tell him why.
C.Teach the child why and how to say sorry to others.
D.Let the child know you still love hime or her.
小題2:What do many parents think they should do with the wrongdoer?
A.Calm themselves down before scolding him.
B.Hide their feelings when talking to him.
C.Explain immediately why he was wrong.
D.Speak strongly and angrily to him.
小題3:What could be the best title for the text?
A.Different Ways to Deal with Children’s Wrongdoings
B.Differences among Parents in Dealing with Children
C.Best Ways to Stop Children’s Wrongdoings
D.Research on Preventing Children from Hurting Others

When an emergency situation occurs, observers are more likely to take action if there are few or no other witnesses.This phenomenon is referred to as the bystander effect.
The bystander effect is also called the Genovese effect, which was named after Catherine Kitty Genovese, a.young woman who was murdered on March 13, 1964.Early in the morning, 28-year-old Genovese was returning home from work.As she approached her apartment entrance, she was attacked and stabbed(刺)by a man later identified as Winston Moseley.Despite Genovese]s repeated cries for help , none of the dozen or so people in the nearby apartment building who heard her cries called the police for help .The attach first began at 3:20 , but it was not until 3:50 that someone first contacted the police.
There are two major factors that contribute to the bystander effect.First, the presence of other people creates a diffusion(分散)of responsibility.Because there are other observers, individuals do not feel as much pressure to take action, since the responsibility to take action is thought to be shared among all of those present.
The second reason is the need to behave in correct and socially acceptable ways.When other observers fail to react, individuals often take this as a signal that a response is not needed or not appropriate.Other researchers have found that onlookers are less likely to take action if the situation, is ambiguous^ R^E^?).In the case of Kitty Genovese, many of the 38 witnessing reported that they believed that they were witnessing a " lovers' quarrel" , and did not realize that the young woman was actually being murdered.
小題1:The passage seems to suggest that Genovese might not have been murdered if there had been_____.
A.no observerB.fewer observers
C.more observers .D.younger observers
小題2:Genovese was murdered                   .
A.while she was going outB.in her apartment
C.halfway homeD.in front of her apartment ?
小題3:The underlined word "this" in the last paragraph probably refers to ____.
A.not doing anything to helpB.behaving in correct ways
C.taking actionD.murdering
小題4:We can learn from the passage that Genovese's neighbors didn't lend a hand partly because they ____.
A.were afraid of being attacked by the murderer
B.thought someone else might come to her rescue.
C.didn't get along well with her
D.were sure it was murdering

It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil) creating a greenhouse effect-holding in heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.
Another view, less widely held, is that increasing particulate matter in the atmosphere is blocking sunlight and lowering the earth’s temperature-a result that would be equally disastrous(災(zāi)難的). A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. At present we do riot know for sure that either of these conditions will happen(though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we very lucky, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now.
小題1:As pointed out at the beginning of the passage, people used to think that air pollution ______.
A.caused widespread damage in the countryside
B.a(chǎn)ffected the entire eastern half of the United States
C.a(chǎn)lmost brought worldwide effect
D.existed merely in urban and industrial areas
小題2:As far as the greenhouse effect is concerned, the author _____________.
A.shares the same view with the scientists
B.is uncertain of its occurrence
C.rejects it as being ungrounded(無根據(jù)的)
D.thinks that it will increasingly destroy the world soon
小題3:It can be inferred from the passage that                   .
A.raising the world’s temperature a little would not do much harm to life on the earth
B.lowering the world’s temperature a little would lead to agricultural disasters
C.a(chǎn)lmost no temperature variations have occurred over the past decade
D.the world’s temperature will remain stable forever
小題4:This passage is primarily concerned with             .
A.the greenhouse effect in the world
B.the measures to adjust the climate
C.the potential effect of air pollution

Who's in control of your life? Who is pulling your string? For the majority of us, it's other people-society, colleagues, friends, family or our religious community. We learned this way of operating when we were very young, of course. We were brainwashed. We discovered that feeling important and feeling accepted was a nice experience and so we learned to do everything we could to make other people like us. As Oscar Wilde puts it, “Most people are other people. Their thoughts are someone else's opinions, their lives a mimicry(模仿),their passions a quotation.”
So when people tell us how wonderful we are, it makes us feel good. We long for this good feeling like a drug-we are addicted to it and seek it out wherever we can. Therefore, we are so eager for the approval of others that we live unhappy and limited lives failing to do the things we really want to. Just as drug addicts and alcoholics live worsened lives to keep getting their fix(一劑毒品),we worsen our own existence to get our own constant fix of approval.
But just as with any drug, there is a price to pay. The price of the approval drug is freedom-the freedom to be ourselves. The truth is that we cannot-control what other people think. People have their own agenda(日程安排), and they come with their own baggage and, in the end, they're more interested in themselves than in you. Furthermore, if we try to live by the opinions of others, we will build our life on sinking sand. Everyone has a different way of thinking, and people change their opinions all the time. The person who tries to please everyone will only end up getting exhausted and probable pleasing no one in the process.
So how can we take back control? I think there's only one way-make a conscious decision to stop caring what other people think. We should guide ourselves by means of a set of values-not values imposed from the outside by others, but innate values which come from within. If we are driven by these values and not by the changing opinions and value systems of others, we will live a more authentic(真實的), effective, purposeful and happy life.
小題1:What Oscar Wilde says implies that      .
A.most people's thoughts are controlled by others.
B.we have thoughts similar to those of others.
C.most people have a variety of thoughts.
D.other people's thoughts are more important.
小題2: What does the author try to argue in the third paragraph?
A.The price of taking the drug is freedom.
B.Changing opinions may cost us our freedom.
C.We may lose ourselves to please others.
D.We need to pay for what we want to get.
小題3: It can be concluded from the passage that     .
A.it's important to accept others' opinions.
B.it's better to do what we like.
C.we shouldn't care what others think.
D.we shouldn't change our won opinions.
小題4: The author tries to persuade the readers to accept his arguments mainly by     .
A.making suggestions.B.a(chǎn)nalyzing causes and effects.
C.providing examples and facts.D.discussing questions
