記得小時候看過一部動畫片叫做《沒頭腦和不高興》，里面的兩個主人公一個丟三落四沒頭腦，一個整天不高興，并由此引發了一些鬧劇。今天我們就來說說英語里是怎么表達“沒頭腦”這個意思的。
An airhead is someone whose head is full of air. He or she hasn’t got any sensible or realistic ideas and is rather a silly and unintelligent person.
Airhead指腦中除了空氣，空無一物的人，即我們所說的“空腦殼”或“沒腦子的人”。他們的腦子想不出任何有現實意義的主意，基本上屬于愚鈍、缺少智慧的人。
For example:
Michael forgot to bring his passport for his flight to Sydney. What an airhead!
邁克爾去趕飛往悉尼的飛機，但忘記帶護照了。真是沒腦子！
The opposite of an airhead is an egghead. An egghead is a very studious and intellectual person. However it isn’t always used in a complimentary manner.
Airhead的反義詞是egghead，指學識淵博的人，但有時在句子里不一定表示褒獎。
For example:
John is such an egghead, he should get out more and enjoy himself.
約翰都快成書呆子了，他應該多出去轉轉，放松一下。
