    Scientists Alan M．Goldberg and Thomas Hartung describe recent advances in replacing the use of animals in toxicology(毒物学)testing．Improvements in cell and tissue culture technologies，for example，allow a growing number of tests to be performed on human cells alone．Computer models are becoming increasingly complex and many could one day become more accurate than trials in living animals．
    Since the late 1990s，Huntingdon Life Sciences--a company that conducts testing of substances on animals conducted by the Environmental Protection Agency and the Food and Drug Administration—has become a proving ground for aggressive strategies by animal-rights militants （好战分子）．At a hearing，a Senate．committee listened to testimony（证词） against Huntingdon employees and financial institutions providing services to the company．One experimentation witness at the hearing insisted that any means necessary were justified（辩护） to spare animals’ lives；he has previously accepted the idea of murder to that end．
    Use of animals in testing and in biomedical research continues to be necessary in many instances and is ethically（伦理道德地）preferable to experimenting on humans or giving up cures that could save human lives．But for the sake of people and animals alike，the development and acceptance of animal substitutes deserve enthusiastic support．
    In some instances, substitutes are already thought as good or better than animals，but supervising agencies（监督机构）have yet to catch up．In both the European Union and the U．S．，scientists and companies wanting to use the new alternative tests complain that regulatory standards for proving a drug or chemical to be safe for humans force the continued use of animals．Thus，animal-loving Americans might turn to persuading the EPA and the FDA to speed validation（确认）of new methods so that they can be more widely employed．And animal advocates（保护者） who want to influence business could consider investing in the small biotech’s and large pharmaceutical（药品的） companies that are working to develop alternatives to animals in research．

    1. 1.

      _____ plays a leading role in replacing the use of animals in testing．

      1. A.

        animals shouldn’t be used in toxicology testing
      2. B.
        animals should enjoy equal rights with human beings
      3. C.
        animals should live wildly and freely
      4. D.
        we should protect animals from being killed casually

      2. B.
        The new trend in toxicology testing
      3. C.
        The use of animals in testing is against human nature
      4. D.

    Eddie’s father used to say he’d spent so many years by the ocean, breathing seawater. Now, away from that ocean, in the hospital bed, his body began to look like a beached fish. His condition went from fair to stable and from stable to serious. Friends went from saying, “He’ll be home in a day,” to “He’ll be home in a week.” In his father’s absence, Eddie helped out at the pier (码头), working evenings after his taxi job.
    When Eddie was a teenager, if he ever complained or seemed bored with the pier, his father would shout, “What? This isn’t good enough for you?” And later, when he’d suggested Eddie take a job there after high school, Eddie almost laughed, and his father again said, “What? This isn’t good enough for you?” And before Eddie went to war, when he’d talked of marrying Marguerite and becoming an engineer, his father said, “What? This isn’t good enough for you?”
    And now, regardless of all that, here he was, at the pier, doing his father’s labor.
    Parents rarely let go of their children, so children let go of them. They move on. They move away. It is not until much later, as the heart weakens, that children understand: their stories, and all their accomplishments, sit on top of the stories of their mothers and fathers, stones upon stones, beneath the waters of their lives.
    Finally, one night, at his mother’s urging, Eddie visited the hospital. He entered the room slowly. His father, who for years had refused to speak to Eddie, now lacked the strength to even try.
    “Don’t sweat it, kid,” the other workers told him. “Your old man will pull through. He’s the toughest man we’ve ever seen.”
    When the news came that his father had died, Eddie felt the emptiest kind of anger, the kind that circles in its cage.
    In the weeks that followed, Eddie’s mother lived in a confused state. She spoke to her husband as if he were still there. She yelled at him to turn down the radio. She cooked enough food for two. One night, when Eddie offered to help with the dishes, she said, “Your father will put them away.” Eddie put a hand on her shoulder. “Ma,” he said, softly, “Dad’s gone.”
    “Gone where?”

    1. 1.

      1. A.
        Children like moving away from their parents

        Children often feel regretful because they leave their parents
      3. C.
        Children wouldn’t have achieved so much without their parents’ support
      4. D.
        Children can never understand how much their parents have devoted to them
    2. 2.

      The underlined sentence “Don’t sweat it” (Para. 6) probably means______.

      1. A.
        Don’t touch it
      2. B.
        Don’t give it up
      3. C.
        Don’t let him down
      4. D.
        Don’t worry about it
    3. 3.

      Which of the following shows the right order of the story?
      a. Eddie’s father died.
      b. Eddie married Marguerite.
      c. Eddie worked as a taxi driver.
      d. Eddie was bored with his father’s job

    Do dogs understand us?
    Be careful what you say around your dog. It might understand more than you think.
    A border collie博德牧羊犬 named Rico recognizes the names of about 200 objects, say researchers in Germany. The dog also appears to be able to learn new words as easily as a 3-year-old child. Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).
    In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects. Then the owner told the dog to go and fetch one of the items and bring it back. In four tests, Rico got 37 out of 40 commands right. As the dog couldn't see anyone to get clues, the scientists believe Rico must understand the meanings of certain words.
    In another experiment, the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew. The owner then told Rico to fetch the object, using a word the dog had never heard before.
    The correct object was chosen in seven out of l0 tests, suggesting that the dog had worked out the answer by the process of elimination(排除法). A month later, Rico remembered half of the new names, which is even more impressive.          
    Rico is thought to be smarter than the average dog. For one thing, Rico is a border collie, a breed (品种)known for its mental abilities. In addition, the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.
    It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your dog every now and then. You might just get a big, wet kiss in return!

    1. 1.

      From paragraph 2 we know that ____________

      1. A.
        animals are as clever as human beings
      2. B.
        dogs are smarter than parrots and chimpanzees
      3. C.
        chimpanzees have very good word-learning skills
      4. D.
        dogs have similar 'learning abilities as 3-year-old children
    2. 2.

      1. A.
        Rico is smart enough to get all commands right
      2. B.
        Rico can recognize different things including toys
      3. C.
        Rico has developed the ability of learning mathematics
      4. D.
        Rico won't forget the names of objects once recognizing them

      3. C.
        The border collie is world-famous for recognizing objects
      4. D.
        Rico is born to understand its owner's commands

    Have you ever picked a job based on the fact that you were good at it but later found it made you feel very uncomfortable over time? When you select your career, there's a whole lot more to it than assessing your skills and matching them with a particular position. If you ignore your personality, it will hurt you long-term regardless of your skills or the job's pay. There are several areas of your personality that you need to consider to help you find a good job. Here are a few of those main areas;
    1) Do you prefer working alone or with other people?
    There are isolating jobs that will drive an outgoing person crazy and also interactive jobs that will make a shy person uneasy. Most people are not extremes in either direction but do have a tendency that they prefer. There are also positions that are sometimes a combination of the two, which may be best for someone in the middle who adapts easily to either situation.
    2) How do you handle change?
    Most jobs these days have some elements of change to them, but some are more than others. If you need stability in your life, you may need a job where the changes don't happen so often. Other people would be bored of the same daily routine.
    3) Do you enjoy working with computers？
    I do see this as a kind of personality characteristic. There are people who are happy to spend more than 40 hours a week on a computer, while there are others who need a lot of human interaction throughout the day. Again, these are extremes and you'll likely find a lot of positions somewhere in the middle as well.
    4) What type of work environment do you enjoy？
    This can range from being in a large building with a lot of people you won't know immediately to a smaller setting where you'll get to know almost all the people there fairly quickly.
    5) How do you like to get paid?
    Some people are motivated by the pay they get, while others feel too stressed to be like that. The variety of payment designs in the sales industry is a typical example for this.
    Anyway, these are a great starting point for you. I've seen it over and over again with people that they make more money over time when they do something they love. It may take you a little longer, but making a move to do what you have a passion for can change the course of your life for the better

    1. 1.

      What does the underlined sentence in paragraph one mean?

      1. A.
        Before you select your job, you should assess your skills and match them with your position
      2. B.
        There are more important things than assessing skills and match them with the position when you select jobs
      3. C.
        Nothing is important than assessing skills and match them with the position when you select job
      4. D.
        You should ignore your skills when you select job
    2. 2.

      Which of the following is TRUE according to the passage?

      1. A.
        Isolating usually drive people mad
      2. B.
        Interactive jobs make people shy easily
      3. C.
        Extreme people tend to work with others
      4. D.
        Almost everyone has a tendency in jobs
    3. 3.

      The underlined word “stability” in the passage most probably means?

      1. A.
        no movement
      2. B.
        no anger
      3. C.
        gentleness
      4. D.
        enthusiasm
    4. 4.

      In a job search, what quality is not mentioned in the passage?

      1. A.
        Outgoing
      2. B.
        Motivated
      3. C.
        Cooperative
      4. D.
        Passionate
    5. 5.

      What could be the best title for this passage?

      1. A.
        Lifestyles and Job Pay
      2. B.
        Jobs and Environment
      3. C.
        Job Skills and Abilities

    When I was in the seventh grade, I was a candy striper (义工) at a local hospital in my town. I volunteered(自愿做) about 30 to 40 hours a week during the summer.
    Most of the time I spent there was with Mr. Gillespie. He never had any visitors, and nobody seemed to care about his condition. I spent many days there holding his hand and talking to him, helping with anything that needed to be done. He became a close friend of mine, even though he responded with only an occasional squeeze (紧握) of my hand. Mr. Gillespie was in a coma (昏迷).
    I left for a week for a vacation with my parents, and when I came back, Mr. Gillespie was gone. I didn’t have the courage to ask any of the nurses where he was, for fear they might tell me he had died. So with many questions unanswered, I continued to volunteer there through my eighth-grade year.
    Several years later, when I was a junior in high school, I was at the gas station when I noticed a familiar face. When I realized who it was, my eyes filled with tears. He was alive! I got up the nerve to ask him if he was Mr. Gillespie, and if he had been in a coma about five years ago. With an uncertain look on his face, he replied yes. I explained how I knew him, and that I had spent many hours talking to him in the hospital. His eyes welled up with tears, and he gave me the warmest hug I had ever received.
    He began to tell me how, as he lay there comatose (昏睡的), he could hear me talking to him and could feel me holding his hand the whole time. He thought it was an angel(天使), who was there with him. Mr. Gillespie firmly believed that it was my voice and touch that had kept him alive. Then he told me about his life. We exchanged a hug, said our good-byes and went our separate ways.
    Although I haven’t seen him since, he fills my heart with joy every day. I know that I made a difference between his life and his death. As importantly, he has made a great difference in my life. I will never forget him and what he did for me: He made me an angel

    Every day 25 million U.S. children ride school buses. The safety record for these buses is much better than for passenger cars; but nevertheless, about 10 children are killed each year riding on large school buses, and nearly four times that number are killed outside buses in the loading zones. By and large, however, the nation’s school children are transported to and from school safely.
    Even though the number of school bus accidents is not large, the safety of children is always of intense public concern. While everyone wants to see children transported safely, people are divided about what needs to be done-particularly whether seat belts should be compulsory.
    People in favor of seat belts on school buses-many of them parents and medical organizations-argue that seat belts are necessary not only to reduce fatality and injury, but also to teach children lessons about the importance of using them routinely in any moving vehicle. A side benefit, they point out, is that seat belts help keep children in their seats, away from the bus driver.
    People who object to seat belt installation suggest that children are already well protected by the school buses that follow the Nation Highway Traffic Safety Administration’s (NHTSA) safety requirements set in 1977. They also believe that many children won’t wear seat belts anyway, and that may damage the belts or use them as weapons to hurt other children.
    A new research council report on school bus safety suggest that there are alternate safety devices and procedures that may be more effective and less expensive. For example, the study committee suggested that raising seat backs four inches may have the same safety effectiveness as seat belts.
    The report sponsored by the Department of transportation at the request of Congress, reviews seat belts extensively while taking a broader look at safety in and around school buses

    1. 1.

      According to the passage, the “school bus” is _________

      1. A.
        the bus offered by the school and different from the public bus

        the bus that has no difference from the public bus
      3. C.
        the bus that is driven by the students
      4. D.
        the bus that is not safe
    2. 2.

      According to the passage, who has the greatest degree of control of the school buses “safety”?

      1. A.
        A new Research Council
      2. B.
        The Department of Transportation
      3. C.
        The Medical Organization
      4. D.
        National Highway Traffic Safety Administration
    3. 3.

        proposals of seat belts on school buses would be seriously considered
      3. C.
        an alternate safety device (raising seat backs four inches) may be taken into consideration

    Peter Rabbit is a character in various children’s stories written by Beatrix Potter(1866-1943). Peter Rabbit made his first appearance in 1902 in The Tale of Peter Rabbit. Peter doesn’t obey his mother’s orders and goes away.  Mr.McGregor spots him and runs after him. Peter manages to escape, but not before losing his jacket and shoes, which Mr.McGregor uses to dress a scarecrow(稻草人). Peter returns home tired and ill.
    In the Tale of Benjamin Bunny, first published in 1904, Peter’s cousin Benjamin Bunny brings him back to Mr.McGregor’s garden and they get back the clothes Peter lost in The Tale of Peter Rabbit. But after they gather onions to give to Peter’s mother, they are caught by Mr.McGregor’s cat. Benjamin’s father arrives and rescues them, but also blames Peter and Benjamin for going into the garden. In this tale, Peter displays fear about returning to the garden.
    In the The Tale of the Flopsy Bunnies, first published in 1909, Peter has a small role and appears only briefly. He is grown up and his sister Flopsy is now married to Benjamin Bunny. The two are the parents of six little Flopsy-Bunnies. Peter and his mother keep a nursery garden and the bunnies come by asking him for spare cabbage.
    In the Tale of Mr. Tod, first published in 1912, Benjamin and Flopsy’s children are taken away by Tommy Brock. Peter helps Benjamin run after Brock, who hides out in the house of the fox Mr. Tod. Mr. Tod finds Brock sleeping in his bed and as the two get into a fight, Peter rescues the children.
    Peter makes cameo appearances(客串出场) in two other tales. In The Tale of Mrs. Tiggy-Winkle, first published in 1905, Peter and Benjamin are customers of Mrs. Tiggy-Winkle, a hedgehog(刺猬) washerwoman. In The Tale of Ginger and Pickles, first published in 1909, Peter and other characters from Potter’s previous stories make cameo appearances

    Everyone may all have the experience of feeling anxious and stressed when having a rough day or having some troubles. Different people may choose different ways to deal with it, and for most people a break for a 10-minute walk may be quite useful.www.zxxk.com
    Anyway, here is another way around: to get a piece of chewing gum, and chew it. According to a Swinburne University of Technology study, gum-chewing has been found to “relieve anxiety, improve alertness(机敏性) and reduce stress among individuals in a laboratory setting.”
    Some may argue that a laboratory is not the same as an office. But check out the conditions of the study: individuals were monitored while performing “a group of ‘multi-tasking’ activities.” Doesn’t it sound like the situation in the office?www.zxxk.com
    Here’s a summary of some of the study’s findings:
    Gum chewers showed a reduction in anxiety as compared to non-gum chewers by nearly 17 percent during mild stress and nearly 10 percent in appropriate stress.
    Gum chewers showed improvement in alertness over non-gum chewers by nearly 19 percent during mild stress and 8 percent in moderate stress.
    Improved Performance: Chewing gum resulted in a big improvement in overall performance on multi-tasking activities.
    Although these aren’t major improvements, every little bit works and chewing a piece of gum is a lot quicker and easier than slipping outside for a 10-minute walk. So, how does gum work this magic? In part it does so by lowering the level of cortisol(皮质醇)—a steroid(类固醇) hormone that is released in response to stress in your system.
    A few words of advice before you reach for the gum: don’t crack your gum, and be sure to chew it with your mouth closed. In fact, I’d say keep the gum out of meetings, because it really looks impolite to others around you

    1. 1.
