名詞解釋：　所謂口水歌，就是在一段時(shí)間里，大街小巷里，不停地播放，男女老少都會(huì)哼的那種流行歌曲，它不一定寫(xiě)得很好，但卻很上口，容易被傳唱。旋律似曾相識(shí)，跟著哼哼就會(huì)唱，口水歌，還有另一種意思，就是發(fā)燒CD里，能聽(tīng)到歌手唱歌時(shí)的口水聲。 另一種說(shuō)法是唱片里歌手翻唱的歌曲統(tǒng)稱口水歌。你知道怎么用英語(yǔ)表達(dá)嗎?

　　We've all been there: you hear a catchy song and for days or even weeks on end, you just can't get it out of your head.

　　Known as an earworm or brainworm, the effect has been studied before —— but its cause, and how to get rid of it, is poorly understood.

　　Now researchers say they have an answer —— chewing gum after hearing a catchy song will help you think about it less often.

　　我們都遇到過(guò)這種狀況：你聽(tīng)完一首口水歌后，連續(xù)數(shù)日甚至數(shù)周你都沒(méi)辦法將其在腦海中擺脫掉。

　　這就是俗稱的“耳朵蟲(chóng)”，曾經(jīng)對(duì)“耳朵蟲(chóng)效應(yīng)”進(jìn)行過(guò)研究，但是“耳朵蟲(chóng)”的起源、如何擺脫“耳朵蟲(chóng)”，卻一直令人費(fèi)解。

　　如今研究人員宣稱他們找到了答案——聽(tīng)完口水歌后嚼一嚼口香糖，你就不會(huì)那么頻繁地想起這首歌。

　　研究指出，嚼口香糖也可以被用來(lái)阻止討厭的念頭或想法入侵。

　　文中的catchy song就是“口水歌”的意思，其中catchy是形容詞，指(曲調(diào)、名字或廣告)悅耳的，有吸引力的，瑯瑯上口的，如：The songs were both catchy and original. (那些歌曲既瑯瑯上口，又富有原創(chuàng)性。)

　　最后一句中的intrusive是形容詞，意為“打攪的;侵入的 ”，如：The villagers are warm and courteous but not intrusive.(村民熱情有禮、絕不擾人。)
