问题补充：

valuable advice it is. It will be of great value to me.

A. What a; the

B. What ; /

CHow ; the

DHow ; /

答案：

A. What a; the

(答案→)B. What ; /

C. How ; the

D. How ; /

解析：句意：多么有价值的建议呀！它将对于我来说是非常有价值的。What+(形容词)+可数名词复数或不可数名词+主语+谓语! Advice为不可数名词，而be of great value意为“非常有价值”。相当于very valuable；故选B。
