道选择题在线等：In the past ten years,the man has been____a lot.
A,suffering B,suffering from C,surffered D,suffered from
问题补充：
答案是A,可是为什么选A?不是has been done么?
答：你只知其一,不知其二.不是还有现在完成进行时has been doing sth.
译：在过去的十年里,这男人受了很多苦.
析：suffer 一词,表示“受（苦/难）”,既可作及物动词,也可以作不及物动词.在这里用作及物动词后跟a lot （=much) 作宾语,表示“受了很多苦”.sb.suffers (from) sth.是主动的,所以排除被动的CD
难以讲请的是为什么不用B.这要查词典比较好.
suffer

1 [I,Ipr] (from/with/for sth) feel pain,discomfort,great sorrow,etc 感到疼痛、 不适、 悲伤等; 受苦; 吃苦头

2 [Tn] experience or undergo (sth unpleasant) 经历或遭受（不愉快之事）

从例句可知,suffer from后常跟具体的名词.但suffer sth.与suffer from sth.确实很不好区分.此题B很难说不行.
