  • 第1题:

    They encourage doctors to ________ cheaper medicine instead of more expensive drugs.

    A.swallow

    B.appreciate

    C.admire

    D.prescribe


    答案:D

    解析:题干句意为:他们支持医生()价格更低的药物,而不是更贵的。swallow意为“忍受,吞没”,appreciate意为“增值;欣赏”,admire意为“钦佩,赞美”,prescribe意为“规定,开处方”,所以选D符合句意。

  • 第3题:

    The issue is how to __________ radioactive waste.

    A.deal
    B.dispose
    C.disposal
    D.do

    答案:B
    解析:
    考查动词辨析。句意为“问题是怎样一一放射性废料”。deal(with)意为“处理(事情),应付,做生意”,dispose(of)意为“处理(废物),处置,除掉,去掉”,disposal意为“处理,处置”,是名词,do意为“处理;整顿;解决(问题)”。根据题意,应为处理放射性材料,故选B。
