A. invited; is allowed
B. are invited; are allowed
C. being invited; allowed
D. invited; are allowed
答案:
(答案→)A. invited; is allowed
B. are invited; are allowed
C. being invited; allowed
D. invited; are allowed
解析:考查分词做定语和主谓一致。本题第一空的名词those与动词invite构成被动关系,故使用过去分词短语在句中做定语修饰those;第二空与句子主语nobody保持一致,使用单数形式。句意:除医生和护士和那些胡教授邀请来的人,没有人没有进入病人的房间。故A正确。
