1. To hold water 站得住腳，說(shuō)得通

　　講解：按字面解釋，To hold water當(dāng)然可以說(shuō)是“不讓水漏出來(lái)”。但是，它還可以引申為指某人的論點(diǎn)、借口、理由站得住腳。美國(guó)人經(jīng)常說(shuō)："That excuse simply doesn't hold water." 意思是：那個(gè)借口根本站不住腳。

　　例句：Several of his suggestions about changes in the government simply don't hold water.

　　他有關(guān)改革的意見中有幾條根本說(shuō)不通。

　　2. Like water off a duck's back 毫無(wú)意義

　　講解：鴨子身上的毛就像雨衣一樣，水在上面呆不住，一下全滑掉了。因此，like water off a duck's back指的就是某件事毫無(wú)意義，不起作用。

　　例句：The doctors tell us it's dangerous to smoke, but such good advice rolls off some people like water off a duck's back.

　　醫(yī)生都告訴我們抽煙對(duì)身體是有害的?？墒?，這種合理的建議對(duì)于有些人來(lái)說(shuō)就像耳邊風(fēng)一樣，毫無(wú)作用。”

　　3. To make someone's mouth water 讓某人流口水

　　講解：讓某人嘴里流水自然就是讓某人流口水的意思了。

　　例句：The roast ducks that restaurant serves is my favorite dish. Every time I think about it, it makes my mouth water.

　　我最喜歡吃那個(gè)飯館的烤鴨。每當(dāng)我想起它我就會(huì)流口水。
