下午在做15天速战速决，一道题卡住了
Sun's ray sends radiations which will distort the laboratory experiments on a transitory diversity phenomenon, so whatever can___ their influence is frustrating the scientists.
A increase
B work over
C exchange
D obscure
E clone
答案是d,但题目说的是太阳辐射造成试验失败－是科学家挫败，那 the influence就是指代sun radiation，所以我选了a。。。有谁能demystify一下么？作者: zhucenglin 时间: 2014-7-29 14:34:18
