一、詞義用法問題
1、欣賞，贊賞
That’s because you can’t appreciate music. 這是因為你不能欣賞音樂。
I appreciate his generosity. 我贊賞他的慷慨大方。
2、理解。體會
I appreciate the difficulty. 我理解這種困難。
I am afraid you don’t appreciate America. 恐怕你不理解美國。
3、感謝，感激
I appreciate your goodness in calling. 我感謝你好心來訪。
He appreciated their confidence. 他感激他們的信任。
二、后續(xù)賓語問題
其后可接名(代)詞、動名詞、名詞性從句等作賓語，但不能接不定式。如：
We shall appreciate hearing from you again. 能再次收到你的來信，我們將十分感激。
I appreciate that you have come here so early. 感謝你來得這么早。
注意：其后只能接“事”作賓語，而不能接“人”作賓語 (注意：這與thank 的用法恰恰相反)。
三、后接if或when從句的問題
其后不直接跟if或when引導(dǎo)的從句，若語義上需要接這類從句，需借助it。如：
I would appreciate it very much if you would help me with it.如果你能幫助我做這事，我會十分感激。
We really appreciate it when she offered to help.她來幫忙了，我們十分感激。
