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

試題分析：本題后半句中的be為are，所以主語應該為復數形式，advice為不可數名詞，故不選，suggestion是可數名詞，故第一個空填suggestions，介詞of后應跟名詞價值value，故本題選B。
點評：在英文中，我們應注意表示建議有兩個單詞，一個是advice，為不可數名詞，一條建議可以說成a piece of advice，另一個是suggestion為可數名詞，注意它們的使用和區別。
