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 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。

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。

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.
