    When prehistoric man arrived in new parts of the world, something strong happened to the large animals; they suddenly became extinct. Smaller species survived; the large, slow-growing animals were easy game, and were quickly hunted to extinction. 
    Now something similar could be happening in the oceans. That the seas are being over-fished has been known for years and researchers such as Ransom Myers and Boris Worm have shown how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) inanes fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.
    Dr. Worm acknowledges that these figures are conservative (保守的). One reason for this is that fishing technology has improved. Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around noise.
    Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the date support an idea current among marine biologists, that of the “shifting baseline”. The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.
    【小题1】The aim of the extinction of large prehistoric animals is to suggest that _______.

    A．large animal were not easy to survive in the changing environment
    B．small species survived as large animals disappeared
    C．large sea animals may face the same threat today.
    D．Slow-growing fish outlive fast-growing ones
    【小题2】We can infer from Dr Myers and Dr. Worm’s paper that _______.
    A．the stock of large predators in some old fisheries has reduced by 90%
    B．there are only half as many fisheries are there were 15 years ago
    C．the catch sizes in new fisheries are only 20% of the original amount
    D．the number of larger predators dropped faster in new fisheries than in the old
    【小题3】By saying these figures are conservative (line 1, paragraph 3), Dr worm means that_______.
    A．fishing technology has improved rapidly
    B．then catch-sizes are actually smaller then recorded
    C．the marine biomass has suffered a greater loss
    D．the date collected so far are out of date.
    【小题4】Dr Myers and other researchers hold that _______.
    A．people should look for a baseline that can’t work for a longer time
    B．fisheries should keep the yield below 50% of the biomass
    C．the ocean biomass should restore its original level.
    D．people should adjust the fishing baseline to changing situation.
    【小题5】The author seems to be mainly concerned with most fisheries’ _______.
    A．management efficiency
    B．biomass level
    C．catch-size limits
    D．technological application.

    Jeanne Calment, a French woman, became a record breaker on 17 October of 1995, when at the age of 120 years and 238 days, she became the longest-lived human being on record. A Japanese man died in 1986 at the age of 120 years and 237 days.

    Jeanne Calment lives in a small old people’s home in the south of France; her husband, her only child and her grandson have all died. She is nearly blind and deaf and is always in a wheelchair, but her doctor describes her as being more like a 90-year-old in good health than someone of 120. She still has a lively sense of humor. When asked on her 120th birthday what she expected of the future, she replied: A very short one. She also remarked that she thought the good Lord had forgotten all about her. 

    So what is the key to a long life? According to some doctors, diet, exercise and no smoking are the three important factors. Jeanne Calment has followed two of the tips. She has always eaten a healthy diet, and she used to do exercises every day until she broke her leg at the age of 115. However, until recently she drank two glasses of strong red wine a day, and she does smoke (now only a little). Besides, Jeanne Calment might have got very good genes from her parents. Her father lived to the age of 94 and her mother to 86. 

    A local lawyer bought her house when she was 80 under an agreement that he would pay her some money every year until her death. It must have seemed a good move at that time, but so far the lawyer has paid her at least three times the value of the house. Every year on her birthday Jeanne Calment sends him a card saying:

    Sorry, I’m still alive!

    1. How does Jeanne Calment feel about her old age?

    A. She is miserable and unhappy.

    B. She is cheerful and humorous.

    C. She would like to live much longer.

    D. She feels she is going to die very soon.

    2. Jeanne Calment has a long life because of _______.

    A. smoking only a little every day

    B. her giving up smoking and drinking

    C. drinking two glasses of strong red wine every day

    D. the good genes from her parents, a healthy diet and some exercises

    3. According to the passage, which of the following statements is TRUE?

      A. The Japanese man died earlier than Jeanne Calment by one day.

      B. Jeanne Calment is tired of living so long a life.

      C. Jeanne Calment’s husband, children and grandchildren have all died.

      D. One of Jeanne Calment’s legs was once broken.

    4.Which could best replace the underlined word “move” in the fourth paragraph?

    A. deal         B. trick            C. march        D. sport

    5. Why does Jeanne Calment say “Sorry, I’m still alive” to the local lawyer every year on her birthday?

    A. Because she had an agreement at 80 with the lawyer which was to her advantage.

    B. Because she has asked the lawyer to pay her more rent than they first agreed.

    C. Because the lawyer has paid her much more money than the value of the house.

    D. Because the house she rented to the lawyer isn’t worth the money he has already paid.
