Appreciate 的用法

appreciate是表示感謝,珍惜，增值，請求（would greatly appreciate/ 具有諷刺性） 採我方主動語態, 所以正確用法是:

We appreciate your good hospitality.感謝
We would appreciate it if you kindly.... 先感謝了
We would appreciate your early reply.先感謝了
=Your early reply would be highly appreciated. (對方為主詞, 所以用被動語態, 仍是表我方感謝) or 被對方所珍惜

我方感謝時, We would be appreciated...是錯誤用法, 因為"be appreciated"是被感謝, 例如這樣的句子:
We would be appreciated （被誰？）to serve the different tastes that will make you forget your tiredness in its roomy and comfortable ambiance氣忿.

據我的觀察, 表我方感謝時錯誤使用"we would be appreciated..." 或"We are appreciated..."的情況非常多而不自知.


Point 2:

“we would be appreciated…..” is like “ordering, thanks in advance if you do it our way, we will be happy if you do it our way”. We would be appreciated if you could leave now.

“we would appreciate….” is like “requesting, we will be happy if you do it our way”. We would appreciate greatly if you would stop talking.

“we appreciated…” is like “we thanked”, we appreciated your help.

“we/ you are appreciated…” is like “we've been thank by..”, we/ you are appreciated by the school.

Using past tense (would, could) is more polite.
