问题补充：
I have a lot of interesting topics to discuss with you. Will you come to me after school ?
A. when you are very convenient
B. when it is convenient to you
C. in the convenience of you
D. when it is convenient by you
答案：
A. when you are very convenient
(答案→)B. when it is convenient to you
C. in the convenience of you
D. when it is convenient by you
解析： 考查宾语从句，特殊疑问句的宾语从句做宾语时应用陈述句语序。convenient 方便的，表达某人方便的话，一般不用人做主语，常用句型为：It is convenient to sb … ,句意：我有好多令人感兴趣的话题要和你讨论，放学后当你方便的时候过来好吗？故选B。
