Question

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

A．advice; value	B．suggestions; value
C．advice; valuable	D．suggestion; valuable

Answer 1

B

试题分析：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。
点评：在英文中，我们应注意表示建议有两个单词，一个是advice，为不可数名词，一条建议可以说成a piece of advice，另一个是suggestion为可数名词，注意它们的使用和区别。
