嗨，大家好！我們知道double有「雙倍的」的意思，而talk有「說話」的含義，那麼double-talk是什麼意思呢？
double-talk是個名詞，它的意思是「language that has no real meaning or has more than one meaning and is intended to hide the truth」，即「（為掩蓋事實而說的）含糊其詞的話」
例句：
She accused the ambassador of diplomatic double-talk.
她指責大使在玩弄外交辭令。
下面再介紹幾個和double有關的詞彙：
double-quick
double-quick是副詞，也是形容詞，它的意思是「very quickly」，即「十分迅速，馬上，立即」。in double-quick time的意思等同於「as quickly as possible」，意思是「馬上，儘快」。
例如：
Amy left the room double-quickwhen I started singing.
我剛一開始唱歌，艾米馬上就離開了房間。
Mary shouted at him and he was gonein double-quick time.
瑪麗朝他大喊，他馬上就跑沒影了。
double-team
double-team是個動詞，它的意思是「in basketball, to have two members of a team trying to prevent an opposing player from scoring」，即「（籃球賽中）雙人防守」。
例句如下：
They double-teamedMike in the second half.
下半場他們對邁克實行雙人防守。
double-dip
double-dip可以是形容詞，也可以是動詞。
當它是動詞時，它的意思是「to receive money from two places at the same time, sometimes in a way that is not legal」，即「同時賺兩份錢（常指從事非法活動）」。
當它是形容詞時，它的意思是「used for describing a period of time during which economic activity gets weaker, increases a little, and then gets weaker again」，即「（經濟）二次蕭條的（指經濟剛略有起色，隨即又陷入蕭條）」。a double-dip recession是個常見搭配，意思是「二次蕭條」。
舉個例子：
The economy has not grown since mid-2010 and is now in a double-dip recession.
2010年年中以來經濟一直沒有增長，目前正處於雙底衰退中。
double-digit
double-digit是個形容詞，它的意思是「relating to a number or series of numbers between 10 and 99」，即「兩位數的」。
例子如下：
