A.to the staff of
B.to those who staff
C.to the staffing of
D.and staffing
E.and the staff of
答案选的是C 我选的是A,答案解释称由于前面的duty assignments 是指职责分配,A中是staff,不搭配.但是A中选项与后面部分连起来staff of shifts-人员的变动,这不是搭配的很好么。
2.A majority of international journalists surveyed view nucliear power stations as unsafe at present but that they will, or could, be made sufficiently safe in the future.
A.that they will, or could
B.that they would, or could
C.they will be or could
D.think that they will be or could
E.think the power station would or could
答案选的是D,我选的是E。但是答案D中的they不是存在指代不明的问题吗,答案说E中的would表示虚拟语气,是对未来的否定,但是对未来表猜测不是也用would吗?
