Animals are considered to be endangered if the species is close to extinction throughout all or most of its environment. Animals become endangered for a variety of reasons.
Some animals become endangered when their habitats contain resources for humans. For example, commercial forest cutting in the Amazon Rainforest has seriously reduced the population of many animal species and lead to the extinction of other groups. Land itself is an important resource to humans since it provides us with living space, and when people replace animal habitats with human habitats, it can lead to larger loss of natural species.
Commercial and industrial operations may reduce land or water for animals and pollute their environment. Due to water pollution, the baiji, a fresh water dolphin native to China, was declared extinct, meaning it’s unlikely the population can recover. Even noise pollution from human activities can lead to the disorder of animal behavior.
Another cause that makes animals become endangered is over-fishing or over-hunting. Over-hunting whales led to near extinction of many species of whales.
The introduction of a non-native species to a habitat may make animals become endangered. The native species may not defend against a new one, and the effects can be dangerous. In Australia, the introduction of the common house cat led to the extinction of the red-fronted parakeet and has seriously damaged the populations of several small animals.
Introduced species can also bring new diseases with them. As a result, animals become endangered. Native animals may not have the power to fight against non-native diseases, and population levels can suffer. Another cause of disease is human-introduced chemicals. The use of DDT is believed to be one of the leading causes in driving the California Condor to near extinction.
When animals become endangered, the entire food chain can be affected. For example, in 2008 disease seriously harmed the honeybee, which is largely responsible for pollinating(授花粉) plants, including many fruits and vegetables. Without their pollination, a very large part of the human diet could be reduced. In fact, if the honeybee should become extinct, our life would be affected and billions of dollars would be lost. Therefore, many people argue that when animals become endangered it is in man’s own self-interest to protect them.The passage is mainly about ______.

For the most part, you are probably only exposed to the music that is played on your favorite radio stations and TV shows, music Web sites, or the music that your friends and family members enjoy. While you probably know a lot about your favorite type of music, it can be a rewarding experience to enlarge your horizons (眼界), discovering artists and types of music that you’re not familiar with. Who knows, you might discover you like certain types of music you never even considered.
Have you ever wondered about the history and influences of your favorite types of music? For example, did you know that rock ’n’ roll originated (起源) from the blues, and that the blues began as a form of musical expression for African Americans during slavery(奴隶制度)? Did you know that most hip-hop is heavily influenced by early rhythm blues and jazz?
There are many fun ways to learn about different musical styles and their historical roots. For example, if you like hip-hop, listen to some of your favorite CDs and take note of the samples the performers used to create the songs. There is a possibility that the artist used parts of older songs to create the music. You can go to the library or online to learn more about the artists and listen to more of their music by checking out CDs from the library or downloading songs online for a small fee.
You can learn so much about culture and history just by paying attention to different types of music and what is being expressed in the songs. There are so many different styles of music to learn about, and you owe (欠) it to yourself to make an effort to listen to and learn about them.The main topic of this passage is _______.

When women sit together to watch a movie on TV, they usually talk simultaneously（同时的）about a variety of subjects, including children, men, careers and what' s happening in their lives. When groups of men and women watch a movie together, the men usually end up telling the women to shut up. Men can either talk or watch the screen -- they can' t do both -- and they don' t understand that women can. Besides, women consider that the point of all getting together is to have a good time and develop relationships -- not just to sit there like couch potatoes staring at the screen.
During the ad breaks, a man often asks a woman to explain the plot and tell him where the relationship between the characters is going. He is unable, unlike women, to read the subtle body language signals that reveal how the characters are feeling emotionally. Since women originally spent their days with the other women and children in the group, they developed the ability to communicate successfully in order to maintain relationships. For a woman, speech continues to have such a clear purpose: to build relationships and make friends. For men, to talk is to relate the facts.
Men see the telephone as a communication tool for sending facts and information to other people, but a woman sees it as a means of bonding. A woman can spend two weeks on vacation with her girlfriend and, when she returns home, telephone the same girlfriend and talk for another two hours.
There is no convincing evidence that social conditioning, the fact that girls' mothers talked them more, is the reason why girls talk more than boys. Psychiatrist Dr Michael Lewis, author of Social Behaviour and Language Acquisition, conducted experiments that found mothers talked to and looked at, baby girls more often than baby boys. Scientific evidence shows parents respond to the brain bias of their children. Since a girl’s brain is better organized to send and receive speech，we therefore talk to them more. Consequently, mothers who try to talk to their sons are usually pointed to receive only short grunts in reply.While watching TV with others, women Usually talk a lot because they
| A．are afraid of awkward silence with their families and friends |
| B．can both talk and watch the screen at the Same time |
| C．think they can have a good time and develop relationships |
| D．have to explain the plot and body language to their husbands |
After a vacation with her girlfriend, a woman would talk to her again on the phone for hours in order to .
| A．experience the happy time again |
| B．keep a close tie with her |
| C．recommend her a new scenic spot |
| D．remind her of something forgotten |
What does the author want to tell us most?
| A．Women' s brains are better organized for language and communication |
| B．Women love to talk because they are more sociable than men. |
| C．Men do not like talking because they rely more on facts. |
| D．Social conditioning is not the reason why women love talking. |
Which of the following would be the best title for the passage?
| A．Women Are Socially Trained to Talk |
| B．Talking Maintains Relationships |
| C．Women Love to Talk |
| D．Men Talk Differently from Women |
When you grow up, could you imagine your parents choosing your husband or wife for you? Besides, can you imagine not setting eyes on him or her until your wedding day? This situation is common in India, the Middle East and many parts of Africa. Marriage customs around the world often differ from our own. We don’t realize that people in other places often get married in very different ways—and with different motives.
In many countries, marriage is a practical matter. A marriage provides a safe and stable home for the husband and wife. It also joins two families, which benefits the couple’s parents and makes them happy. Marriage also brings children, making sure the couple will be taken care of in old age. Because marriage is important for the whole family, some cultures don’t let young people choose whom to marry.
Just as there are many different reasons for marriage, there are also many different wedding rituals. Every culture has its own ways of bringing good luck to the happy couple. In a typical Western wedding, the bride seeks good luck by wearing “something old, something new, something borrowed and something blue.” Something old represents the past. Something new represents success in the future. Something borrowed reminds the bride she can get help from her friends and family. And something blue reminds her to be true to her husband.
In Poland, one wedding tradition is not only lucky, but also very practical. The wedding guests pin money to the bride’s dress while she is dancing. The money is meant to bring luck and to help the young couple build their new life. In Bermuda, the young couple plant a tree in the yard of their new home. Once they move in, they take good care of the tree and make it grow. The planting of the tree is a good metaphor（比喻） for marriage. A truly good marriage is something that grows with care.Which of the following statements does NOT support the idea “marriage is a practical matter”?
| A．The husband or wife may have a safe and stable home. |
| B．A marriage brings children to take care of the couple when they are old. |
| C．A marriage benefits both the couple’s families. |
| D．Parents have no duty to help their children get married. |

“Mind over matter” is an English saying meaning that we can control our bodies with our minds. Now scientists are finding increasing evidence that our mind can have a great effect on our physical health. Since our mind influences how we feel, it’s not true to say if someone is ill just because he feels ill.
The influence of the mind on how well we feel is the basis of what is known as the placebo effect. A placebo (which is Latin for “I shall please”) is a harmless, inactive substance. Patients are sometimes given placebo pills and begin to feel better because they believe that they have been given real drugs and expect to respond to them. The placebo effect is very strong: research on pain suggests that up to 30% of the effect of most painkillers is a placebo effect.
So if it is so powerful, why don’t doctors use it today?
According to Dr Persaud, they really do. “All these things like seeing a doctor, going to a hospital, and being scanned(扫描) have a very strong placebo effect,” he says.According to the first paragraph, if you feel ill.
| A．you don’t need to see a doctor |
| B．it doesn’t necessarily mean that you’re physically ill |
| C．you are in good condition |
| D．it is obvious that you suffer from a serious disease |
The English saying “mind over matter” means that .
| A．a sound mind is less important than a good health |
| B．our mind has a strong effect on our body |
| C．our physical health has nothing to do with our mind |
| D．mental health mainly depends on our physical health |
According to the passage, placebos .
| A．may make patients feel worse |
| B．are not effective pills |
| C．are not real drugs |
| D．can relieve all kinds of pains |
From the passage it can be seen that there will be no placebo effect if a patient .
| A．is dressed in white | B．has a physical exam |
| C．takes placebo pills | D．sees a doctor |
“If it rings one more time, I’ll hang up,” Amy thought hopefully, as she waited for someone to answer. Apologizing wasn’t an easy thing to do.
“Hello,” a woman’s voice said. There was no backing out now.
“May I speak to Missy, please?”
“Just a minute.”
In much less than a minute, Missy was on the phone. “Hi, who’s calling?” asked the cheerful voice.
“It’s Amy. I just wanted to tell you that I’m sorry about what I said to you. I didn’t really mean it.” Amy paused, trying to think of what to say next.
“Thank you, Amy. No hard feelings.”
“Missy, you’re a very nice person. You’re a lot nicer than I am!”
Missy laughed. “You’re not so bad, Amy. By the way, I’ve got some great news. Mr.Grumbell said that you were the only candidate for class president. He talked me into being a candidate, too. Isn’t that cool?”
Amy didn’t think the news was cool. Missy was very popular; she’d get a lot of votes. Fortunately, Amy was in a gracious(亲切的) mood. “You’ll be a tough opponent（对手）, Missy,” she said. “May the best woman win.”
