问题补充：
Come and see me whenever .
A. you are convenient
B. it is convenient for you
C. you will be convenient
D. it will be convenient for you
答案：
A. you are convenient
(答案→)B. it is convenient for you
C. you will be convenient
D. it will be convenient for you
解析：考查固定搭配。句意：无论何时，只要你方便，就可以过来看我。whenever引导让步状语从句，相当于no matter when。时间状语从句不能用将来时，排除C、D；it is convenient for sb某人方便的时候。故选B。
