— Can you come on Friday or Saturday? — I’m afraid is possible．I will go to the hospital

问题补充：

— Can you come on Friday or Saturday?

— I’m afraid is possible．I will go to the hospital to look after my friend．

A. either

B. none

C. any

D. neither

答案：

A. either

B. none

C. any

(答案→)D. neither

解析：考查不定代词。Either两者中任何一个；none三者或三者以上任何一个都不；any 不定范围中任何一个；neither两者中任何一个都不。根据句子Can you come on Friday or Saturday可知有两种选择，排除B,C；再根据I will go to the hospital to look after my friend可知我周五和周六都不能来。所以选D。
