As U.S. nuclear attack submarines prowl their familiar haunts deep within the oceans of the world these days, they increasingly are engaged in missions far different from the tasks for which they were built and for which their crews were trained over the last forty years.
(A) they increasingly are engaged in missions far different from the tasks for which they were built
(B) the missions they increasingly engage in are far different than the tasks they were built for
(C) they engage increasingly in missions that differ significantly from the tasks they were built for
(D) the missions they engage in are increasingly different than the tasks for which they were built
(E) they increasingly engage in missions far different than the tasks for which they were built
ans: A
-----------------
我選D
我ㄧ開始以 "for which" 的平行結構刪掉 B & C
剩下的3各.... 其實不會選...
所以就選了依各聽起來好像比較沒那麼怪的...
個人覺得 "they increasingly are engaged" 聽起起來怪怪的
誰可告訴我做這題的思路勒?
