1. 表示“感激”“赞赏”等，通常为及物动词，其后可接名（代）词、动名词、名词性从句等作宾语，但不能接不定式。如：
I really appreciate a good cup of tea. 有好茶一杯，我就真乐在其中了。
I appreciate your giving me so much of your time. 真感激你为我花了这么多时间。
I appreciate being given this opportunity. 非常感谢给了我这个机会。
I appreciate that you have come here so early. 感谢你来得这么早。
其后不直接跟 if 或when引导的从句，若语义上需要接这类从句，需借助 it。如：
We really appreciate it when she offered to help. 她来帮忙了，我们十分感激。
I would much appreciate it if you would arrange this for us. 如果你能替我安排这事，我将非常感激。

2. 其后只能接“事”作宾语，而不能接“人”作宾语；若接“人”作宾语，可考虑用动词thank等。比较：
正：We appreciate your help. 我们感谢你的帮助。
误：We appreciate you for your help.
正：He thanked her for her help. 他感谢她的帮助。
误：He thanked her help.
