核心句型：
He is so full of hot air.
他真是滿(mǎn)口空話(huà)。
full of hot air 直譯過(guò)來(lái)就是：“充滿(mǎn)了熱空氣”。在英語(yǔ)俚語(yǔ)中，hot air是“空話(huà)，大話(huà)和夸夸其談”的意思。所以這個(gè)短語(yǔ)的正確意思是：“滿(mǎn)口空話(huà)，吹牛，夸夸其談”。因此，當(dāng)美國(guó)人說(shuō)"He is full of hot air."時(shí)，他/她要表達(dá)的意思就是:"What he says is just empty talk."、"He is shooting off his mouth."、"What he says is all jaw."。

簡(jiǎn)：別理他，他總是滿(mǎn)口空話(huà)。
