記得小時(shí)候看過一部動(dòng)畫片叫做《沒頭腦和不高興》，里面的兩個(gè)主人公一個(gè)丟三落四沒頭腦，一個(gè)整天不高興，并由此引發(fā)了一些鬧劇。今天我們就來說說英語里是怎么表達(dá)“沒頭腦”這個(gè)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(xiàn)實(shí)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(jī)，但忘記帶護(hù)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 complementary manner。

Airhead的反義詞是egghead，指學(xué)識淵博的人，但有時(shí)在句子里不一定表示褒獎(jiǎng)。

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(yīng)該多出去轉(zhuǎn)轉(zhuǎn)，放松一下。
