    With global warming and melting ice, it isn’t easy being a polar bear anymore. Some studies have predicted that polar bears could die out by the end of the century. The good news is not all researchers think the bears are absolutely disappearing. Scientists at the American Museum of Natural History(AMNH) have published a new paper indicating that things might not be as bad for polar bears as some scientists expect.

    To understand the reason for the researchers’ cautious optimism, we must first understand the factors that are threatening the polar bear’s existence. Polar bears consume a diet of mainly young seals. In order to hunt these seals, polar bears need to rest at the top of sea ice---the same ice that is increasingly melting for most of the year thanks to climate change. In another 50 years, experts expect that the Arctic will be too warm for sea ice to form for half of the year, leaving polar bears without a reliable food source and in serious danger of starvation.

    As it turns out, alternative food sources for the polar bears aren’t completely out of the question. For as long as biologists have tailed after the animals, they’ve seen polar bears eating animals found on land like caribou(驯鹿) and snow geese---as well as the snow geese’s eggs.

    Can polar bears actually survive off these alternative food sources for long periods of time? To figure this out, researchers calculated the nutrients that a caribou and snow geese diet would provide. They found that even adult male polar bears would be able to obtain more calories than would burn in hunting these meals. Moreover, the food would provide the food lecessary to avoid starvation during the summer months.

    Unfortunately, not all polar bears have tended to seek food on land. That said, the researchers expect that necessity would push more polar bears to hunt on land to avoid starvation. They also expect that the bears could learn from their fellow bears how to hunt on land until the practice becomes second nature.

    Before I studied psychology, I used to think that people would laugh when funny things occurred. While I was right about that, I discovered there are lots of other psychological factors that make people laugh other than the funny part of a joke. When someone laughs at a joke, there will usually be more than one reason that makes him laugh—and the more reasons there are, the more powerful the joke will be.

    I was attending a stand-up comedy show in Egypt, and when the man started to make fun of pedestrians crossing streets, everyone laughed their hearts out. The main reason those people strongly laughed was that almost all of them felt angry towards pedestrians who crossed streets carelessly. The joke wasn’t only funny, it also made the audience feel that they were right about being angry at those pedestrians. That is, people were laughing both because of the funny joke and because of the happiness experienced as a result of the psychological support they got.

    The better a joke makes a person feel, and the more it includes other psychological factors, the more the person will like it. For example, if you envy one of your friends, and someone tells a joke that is funny and, at the same time, makes your friend seem stupid, then you will probably laugh at it louder than if you weren’t jealous of him.

    In short, we don’t laugh only when we hear something funny; we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke. I strongly discourage making fun of anyone or belittling someone to make someone else laugh. All I want to explain is that if your joke supports a person’s emotions, he will certainly like it a lot.

    1. What did the author find out after studying psychology?

    A. Only good jokes make people laugh

    B. Many factors lead to people laughing.

    C. Funny things can make people laugh

    D. Laughter can make people healthy.

    2.Why did the audience laugh loud at the pedestrians?

    A. They played a trick on the pedestrians.

    B. The pedestrians behaved in a funny way.

    C. They could feel the pedestrians’ happiness.

    D. Their emotion was approved of by the show.

    3.What does the underlined word “belittling” probably mean?

    A. Annoy B. Blame C. Look down on D. Make up to

    4. What is the author’s attitude towards those who take pleasure in making fun of others?

    A defensive B indifferent C negative D casual

    Do you dream?

    Have you ever visited some strange places in your dreams? In fact people have wondered about these strange places for long. 1. However, they have been valued as necessary to a person’s health and happiness.

    Historically, people thought dreams contained messages from God. It was only in the twentieth century that people started to study dreams scientifically, believing that they tell about a person’s character. 2. He believed that dreams allow a person to express fantasies or fears, which would be socially unacceptable in real life.

    The second theory to become popular was Carl Jung’s compensation theory. Jung, a former student of Freud, said that the purpose of a dream is not to hide something, but rather to communicate it to the dreamer. 3. Thus, people who think too highly of themselves may dream about falling; those who think too little of themselves dream of being heroes.

    Using more recent research, William Domhoff from the University of California found that dreaming is a mental skill that needs time to develop in humans. 4. Until they reach the age of five, they can not express very well what their dreams are about. Once people become adults, there is little or no change in their dreams. The dreams of men and women differ. For instance, the characters that appear in the dreams of men are often other men, and often involve physical aggression.

    The meaning of dreams continues to be difficult to understand. 5. If you dream that a loved one is going to die, do not panic. The dream may have meaning, but it does not mean that your loved one is going to die.

    A. Dreams make up for what is lacking in waking life.

    B. But anyway, people should not take their dreams as reality.

    C. It gives scientists chances to better understand human mind.

    D. They have been considered as meaningless nighttime journeys.

    E. First, there was Sigmund Freud’s theory.

    F. They think their mind is trying to tell them something.

    G. Children do not dream as much as adults.

    In a Station of the Metro

    The apparition of these faces in the crowd;

    Petals on a wet, black bough.

    This is the only Ezra Pound poem that many people will read in their lives. Why? One obvious reason is that it’s just two lines long. The poem, which can be understood as “A man sees a bunch of faces in the subway and thinks they look like flowers on a tree branch,” is an exercise in shortness. Pound wrote it after having a spiritual experience in a Paris metro (subway) station.

    In 1916, the US poet originally thought he could best describe his vision in a painting. Unfortunately, he wasn’t a painter. So he wrote a thirty-line poem, which he didn’t like. He dropped the long version in the waste bin. Six months later, he wrote a shorter poem, but didn’t like that one either. Finally, a full year after the experience, he had been reading short Japanese poems called haikus, and he figured he would try this style. The result, which was published in 1913, is one of the most famous and influential works in modern poetry.

    This poem is one of the monuments (纪念物) of the 20th-century artistic movement known as “Imagism”. Basically, Pound and his friends thought that images (意象) weren’t just decoration: they were the highest form of speech. By finding the right image, the poet can express the true, spiritual reality of a thing, which is more important than using a bunch of adjectives to describe its physical appearance. Thus, “In a Station of the Metro” is a poem that consists of one image expressed with absolute (绝对的) exactness and nothing else.

    To the imagists, the best way to describe an experience is not to use more and more words; the best way is to find exactly the right words. Have you ever told a beloved one that “words can’t express” how much you love them? Well, Pound would say that you’re just being lazy. In his view, words can express anything, even if it takes an entire year to find the right ones.

    1.In the short poem, Ezra Pound .

    A. tells us one of his painful experiences

    B. compares the passengers’ faces to flowers

    C. describes a man walking among the crowd

    D. shows a wet, black tree branch in a metro station

    2.According to the text, “In a Station of the Metro” was .

    A. based on one of Pound’s paintings

    B. first discovered in a waste bin

    C. influenced by haikus

    D. completed in 1916

    3.Pound and his friends .

    A. stressed the importance of using adjectives

    B. were good at describing abstract images

    C. decorated their poems with pictures

    D. used images to express their ideas

    Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That’s why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.

    Years ago, over hunting and the ivory trade were the biggest threats to elephants survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.

    The 21st century brings a different challenge to elephant conservation —land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.

    Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.

    AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.

    The AWF is helping elephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants.

    1.The first paragraph of the text is mainly to tell readers _____.

    A. African elephants are endangered now

    B. there remains a lot to do to protect African elephants

    C. African elephants are popular animals

    D. the number of African elephants has increased over the years

    2.What is the biggest difficulty in protecting African elephants now?

    A. They are still being killed.

    B. Their habitats are being destroyed.

    C. They don’t have enough food.

    D. They can’t live in peace with farmers.

    3.To protect elephants, the AWF does all the following EXCEPT _____.

    A. keeping elephants

    B. protecting elephants’ habitats

    C. doing research on elephants

    D. helping farmers improve their life

    4.What is the best title for the text?

    A. African elephants conservation

    B. Living with African elephants

    C. African elephants’ situation

    D. African elephants being endangered

    If you are sitting, please stand up. Move your legs. Touch your toes if you can. Do anything but sit. New research shows that if you cut down on the time you spend sitting, you might live longer. Sitting less than three hours a day might extend your life by two years. Cutting television time to less than two hours a day can add one point four years to life.

    The human body is designed to move. The fact is just the opposite. Modern lifestyles and office jobs rarely give us the chance to move around. We sit while we’re eating; we sit in the car; we sit while we are watching TV. And most of us sit for many hours at work. Sitting is something we do all the time. On average, Americans sit for four and a half to five hours a day. But that does not make sitting good for us.

    Though you may exercise often, that does not mean you can sit for the rest of your waking hours. We can’t throw away physical activity. It is extremely important. Even if you exercise for 30 minutes a day, what goes on in the other 23 and a half hours a day is also very important.

    Changes are coming to some offices, especially in the design of desks. A “standing desk” lets people stand while they work. Another new design is called the “treadmill desk”. It is an exercise machine that lets you walk slowly in one place. Even some U.S. schools begin to experiment with desks that are part bicycle to keep children moving.

    Many companies may not buy a standing desk for everybody. However, they may get five standing desks or a treadmill desk for their employees and put them in a certain place where people can go for an hour a day to answer their emails or talk on the phone. Experts suggest some other activities: take a walk at lunchtime; walk to the offices and talk directly instead of emailing colleagues. All these activities may help you live longer.

    1.Why should people stand up according to the new research?

    A. They should touch their toes.

    B. Standing more can cure some diseases.

    C. Sitting less does people good and may help people live longer.

    D. They spend too much time watching TV.

    2.What can we learn about sitting?

    A. Sitting is the best position for the body.

    B. People usually have to sit for a long time nowadays.

    C. The more people sit, the better they will be.

    D. Americans sit longer every day than people in other countries.

    3.What does the underlined word “It” in Paragraph 3 refer to?

    A. The walking hour B. Sitting

    C. Standing. D. Exercising

    4.Which of the following is TRUE according to the passage?

    A. The new design of desks can help people sit less.

    B. The “treadmill desk” is used by people to run.

    C. It’s better for school students to use standing desks.

    D. It’s necessary for companies to offer a sitting desk to every employees.
