问题补充：

He is a clever boy. His are of great to us.

A. advice; value

B. suggestions; value

C. advice; valuable

D. suggestion; valuable

答案：

A. advice; value

(答案→)B. suggestions; value

C. advice; valuable

D. suggestion; valuable

解析：本题后半句中的be为are，所以主语应该为复数形式，advice为不可数名词，故不选，suggestion是可数名词，故第一个空填suggestions，介词of后应跟名词价值value，故本题选B。
