    Every year gray whales migrate from the Bering Sea in Alaska to the Baja Peninsula in Mexico.
    Eleven gray whales have died in the San Francisco Bay in the last three weeks．No one knows why the whales are dying.
    Last year 270 whales died along the whales'migration route．Many people think starvation is the cause．This year the dead whales seem to have more blubber(fat)on them.
    Twenty years ago,the gray whale was listed as an endangered species.
    Some scientists think that the larger number of whales makes it hard to find enough food．More whales create more pressure on the food supply,a supply that some scientists say may have dwindled as a result of the warm waters of El Nino.
    Most of the whales have been dead for many days before they are found and studied．This makes it hard to find the reason for death.
    65 whales have been seen in the San Francisco Bay Area this year compared to 17 last year．The whales could be dying from many diseases,but it may be over-population．

    Which of the following is NOT a possible reason for whales dying?

    A.Pneumoni
    B.Brain infectio
    C.Over-populatio
    D.Over-eatin

    B

    will inhabit

    C

    will have inhabited

    D

    is going to inhabit


    正确答案： A
    解析：
    句意：到2060年的时候，将有相当于现在两倍的人居住在地球上。By the year 2060是By后加表示将来时间的介词短语在句中作时间状语，句子的谓语要用将来完成时态，表示到将来某个时间为止的动作。inhabit意为“居住于；栖息”，是及物动词，其后通常跟地点。如果地点作主语，要用被动语态，因此A选项正确。
