詞：viable
英英釋義：able to be done, or worth doing
例句：Renewables are economically viable alternatives.
2. 為什么選這個詞柒傻？
“viable”是個形容詞澎现，它本身的意思是“可以存活的”，常被引申使用表示“可行的” “值得做的”。正如健康的生命才可以存活，好的想法、產(chǎn)品恰响、解決方案才能存活，我們可以用 viable 來形容表示想法涌献、產(chǎn)品、解決方案這一類詞首有，也逞嗬可以用它替換 effective, feasible 等詞。
在產(chǎn)品設(shè)計中井联，有個概念叫“最簡可行產(chǎn)品”卜壕，它的英文就是 Minimum Viable Product（MVP），我們可以從它的英文解釋中體會一下 viable 的意思：
A minimum viable product (MVP) is a product with just enough features to satisfy early customers and to provide feedback for future product development.
這里的 viable 就可以理解為“satisfy early customers”烙常。如果一個產(chǎn)品可以滿足用戶的需求轴捎，實現(xiàn)盈利鹤盒，那它就是一個 viable product。
比如星巴克在某一個四線城市開店半年以來侦副，收入明顯好于預(yù)期侦锯，就可以說：
Starbucks' new store in this fourth-tier city has proved commercially viable.
從經(jīng)濟(jì)角度來看，可再生能源是合適的替代能源秦驯。用英文可以說成：
Renewables are economically viable alternatives.
《經(jīng)濟(jì)學(xué)人》在一月份一篇講電腦芯片的文章中就用到了 viable：
To keep its design pipeline full of viable new ideas, the firm must constantly forecast the computer industry’s direction.
3. 怎樣學(xué)會使用這個詞尺碰？
1）使用《牛津英語搭配詞典》查“viable”，了解它作為形容詞時的常用搭配译隘。
2）翻譯下面的句子：
中國經(jīng)濟(jì)下行亲桥，許多 O2O 模式顯得不再可行。
As China’s economy is going downhill, many O2O businesses no longer seem viable.
參考翻譯：As China’s economy is going downhill, many online-to-offline (O2O) businesses no longer seem (commercially/economically) viable.
2.Since the financial problem,Ofo seems no longer viable.
