劍橋字典里的解釋：

something you say to someone when they have been nice and helpful to you（表示感激某人）

你真是個(gè)大好人！

如果他人為你提供幫助，你為此不勝感激就可以說(shuō)：You're a star（你真是太好啦?。?/p>

??例句：

I really appreciate what you did for me. You're a star! Thanks a million.

我真的很感激你為我所做的一切。你真是個(gè)大好人! 萬(wàn)分感謝。

溫馨提示：如果你真是有粉絲的明星，You're a star=你是個(gè)明星。

聽(tīng)到別人說(shuō)“I could see stars”，別理解為是浪漫的看星星。

see stars的真正意思是“眼冒金星”

watch a star才是觀看星星

observe a star的意思是觀察星球

?? 例句：

I felt a little dizzy[?dizi]  and could see stars.

我感覺(jué)有點(diǎn)暈，眼冒金星了。
