Thanks a lot/Thanks a bunch/I appreciate it/It means a lot to me/I don't know what to say/That was kind of you/Thank you so much/Thank you very much.

非常謝謝用英語可以這么說：

1. Thanks

后面加上不同的詞，就成了Thank you so much. / Thank you very much. / Thanks a lot./ Thanks a bunch。

2. I can't thank you enough.

Can't do sth enough就是再怎么都不為過，這句話就是無法形容對你有多感謝，感激不盡。

3. Cheers

Cheers在英國和澳洲更通用哦。

"I've bought you a drink." "Cheers, mate."

“我給你買了杯酒。”“謝謝，老兄。”
4. I appreciate it.

I/we appreciate這個表達形容我／我們對…非常感謝。

We really appreciate all the help you gave us last weekend.

你們上周末給予我們大力幫助，我們非常感謝。
5. I'm grateful for that/it.

你可以加一點副詞，增強感謝的程度哦，比如：

I'll be eternally grateful to you.
我永遠感激你。
6. It means a lot to me.

這個程度就更深啦，別人幫了大忙就可以這么說。

7. That was very kind of you.

It was great/awesome/thoughtful of you.

如果朋友做了很暖心的事情，以上的表達都很實用哦。

8. Oh, you shouldn't have.

比如別人給你禮物時，用來表示你沒有期待如此。

對應中文就是“你太客氣了”，比如：

Flowers! You shouldn't have!
“給我的鮮花！你不必送的！”
9. I don't know what to say.

形容激動地說不出話來。
