  • 第5题：

    单选题
    In fisheries in general, when a large harvest is taken one year, there will be fewer fish available to be harvested in the following year, leading to decreasing yields of most fish species over time. The Maine lobster is an anomaly, however. Even though the vast number of lobster traps covering the New England coast pull in more lobsters every year, the number of lobsters in the water has shown no signs of decreasing.Which of the following, if true, most helps to explain the apparent anomaly concerning the number of Maine lobsters?
    A

    The decline of other fish species in the region has deprived the lobster of its natural food source of scavenged fish.

    B

    The bait in lobster traps provides abundant food for young lobsters, which are still small enough to swith out of the traps, leading to much higher survival rates among young lobsters than would be expected in nature.

    C

    As global warming heats the waters of the Atlantic coastline, the Maine lobster has extended its northern range to well past Nova Scotia.

    D

    The ever increasing demand for lobsters in seafood restaurants and steakhouses across the country has driven a corresponding increase in the supply of the product.

    E

    The increased lobster harvest has resulted in many iuvenile lobsters but very few breeding- age lobsters, which could result in a crash in lobster numbers in the near future.

    D

    正确答案： D
    解析：
    细节题。第三段最后一句指出“This macabre scenario may help solve several sea mysteries, such as why fishermen report seeing “fish walks” （fish trying to leave the water）…”，该句括号里的内容是对“fish walks”的解释，由此可知“fish walks”的原因是被这些微生物麻痹了神经，从而呼吸困难。因此选D。
