Canadian scientists have calculated that one human being should be struck every nine years by a meteorite, while each year 16 bulidings can be expected to sustain damage from such objects.
B a human being should be struck by a meteorite once in every nine years.
C a meteorite will strike one human being once in every nine years.
D every nine years a human being will be struck by a meteorite.
E every nine years a human being should be struck by a meteorite.
答案时D,终于弄明白了。可是对于while 从句不明白,such objects代什么呢,从意思来说好像指代a meteorite,可是such objects 又是复数,难道指代scientists,可是明显不通呀?很苦恼! who can help me? |
