选哪个,为什么?
The news of the president's death __ him ,I found him __ on the beach sadly.a.astonished,seatedb.astonished at,sittingc.puzzled,seatingd.puzzled for,sat选哪个,为什么?
选A
astonish表示“震惊”,一般用法为sth.astonish(es) sb.表示某事令某人感到很震惊.
puzzle表示“困惑”,用法与astonish一样,表示某事令某人困惑.
两个词后面都不加at 或者for,直接跟sb,所以B和D选项可以排除；
从意思上看,总统死了的新闻是肯定令人震惊而不是困惑的,这是选A的原因之一.
现在看第二空.
正常情况下是find sb.doing sth.,但seat这个词有点特殊.
seat作动词用时有使动用法,就是seat sb.让某人坐,如果是自己坐就是 I seat myself,这里是“我发现他坐在沙滩上”,要用被动,“他（被他自己）坐在沙滩上”,如果坚持ing形式就必须是I found him seating himself on the beach sadly.
如果用sit,就用sitting形式,不知道这样解释懂不懂,有点绕.
C
astonished at ：对xx感到惊奇
puzzled for：对xx感到疑惑
puzzle sb：使某人疑惑←正解
find sb do：发现某人做过某事
find sb doing：发现某人正在做某事
