. 認(rèn)識(shí)這個(gè)詞（基礎(chǔ)篇）? ?
詞：slippery slope
英英釋義：a bad situation or habit which, after it has started, is likely to get very much worse
例句：Once you start to lie, you are on a slippery slope.
2. 體會(huì)這個(gè)詞 （進(jìn)階篇）
“slippery slope”是個(gè)習(xí)慣表達(dá)蹂空，它的字面意思是“光滑的斜坡”俯萌，常用來表示“滑向深淵的道路”，如果不及時(shí)采取措施這種狀況就會(huì)變得更糟上枕。它是個(gè)非常形象咐熙、適合用在口語和寫作中的精彩表達(dá)，當(dāng)我們想表達(dá)“something becomes worse”時(shí)就可以用 slippery slope 來替換姿骏。
比如我們常說糖声，撒了一個(gè)謊，結(jié)果需要無數(shù)個(gè)謊言來彌補(bǔ)分瘦，結(jié)果就會(huì)一步錯(cuò)步步錯(cuò)蘸泻，就可以用“slippery slope”說成：
Once you start to lie, you are on a slippery slope.
或者
The first fib can put you on a slippery slope to bigger lies.
我們還常說“拆東墻補(bǔ)西墻”，時(shí)間久了就會(huì)越來越糟糕嘲玫，債臺(tái)高筑悦施。這時(shí)就可以說：
We've been on a slippery slope of borrowing more money to pay off the debts we already owe.
或者
Over-borrowing will inevitably lead the borrower down a slippery slope.
《經(jīng)濟(jì)學(xué)人》中也經(jīng)常用到 slippery slope，比如在報(bào)道“協(xié)助死亡”（assisted dying）時(shí)說：
And evidence from places that have allowed assisted dying suggests that there is no slippery slope towards widespread euthanasia.（這句話是說允許協(xié)助死亡并不會(huì)導(dǎo)致越來越多的人選擇安樂死）
slippery slope 和我們之前學(xué)過的 go downhill 差不過去团，可以借此復(fù)習(xí)一下 downhill（點(diǎn)擊直接跳轉(zhuǎn)）的用法抡诞。
3. 從認(rèn)識(shí)到會(huì)用（作業(yè)）
1）翻譯下面的句子：
他的傲慢與固執(zhí)將注定他會(huì)走向失敗。
（參考翻譯: His arrogance and obstinacy will lead him down a slippery slope to failure. ）
2）結(jié)合自己的生活土陪、學(xué)習(xí)昼汗、工作、興趣等鬼雀，想象在什么語境下會(huì)用到這個(gè)表達(dá)顷窒。先簡要描述這個(gè)場景，再造句源哩。
場景：? 貪婪是萬惡之源
造句：And evidence from prisons suggests that there is slippery slope towards evil once the door of greed? is opened.
