兩個題目請教 #913 #25

以下是引用jeffyang在2003-11-5 0:25:00的发言：
這裡有一道題目：
When Medicare was enacted in 1965, it was aimed at the prevention of a catastrophic illness from financially destroying elderly patients.
(a) at the prevention of a catastrophic illness from financially destroying elderly patients
(b) at being a preventative against catastrophic illness financially destroying elderly patients
(c) at preventing a catastrophic illness from financially destroying the elderly patient
(d) to prevent a catastrophic illness financially destroying an elderly patient
(e) to prevent elderly patients being financially destroyed by a catastrophic illness

Answer (c)

那照這樣來看，跟#913比起來，似乎就是主動用aim to ，被動用aim at ，是不是？
謝謝
