一、結(jié)構(gòu)分析
主句——One obvious reason is一個明顯的原因是
多重復合句構(gòu)成的表語從句——that the retired workers once devoted their life to the out-of-date industry which cannot survive in nowadays' modern world since it is known to all that the recent prevailing industry is environmental-friendly and high-tech ones 其中——
復合主句：One obvious reason is that the retired workers once devoted their life to the out-of-date industry which cannot survive in nowadays' modern world 其中——
* 主語：the retired workers once devoted their life to the out-of-date industry 退休工人曾經(jīng)把自己的一生獻給了落伍的行業(yè)
* 嵌套定語從句：which cannot survive in nowadays' modern world 這種行業(yè)在當今世界不能繼續(xù)存在下去
* 嵌套原因狀語從句：since it is known to all that the recent prevailing industry is environmental-friendly and high-tech ones.其中——
-- 形式主語+謂語部分：it is known to all 眾所周知
-- 拖后的主語從句：that the recent prevailing industry is environmental-friendly and high-tech ones 現(xiàn)在占優(yōu)勢的行業(yè)是環(huán)保行業(yè)和高科技行業(yè).
【改為正常語序即為——That the recent prevailing industry is environmental-friendly and high-tech ones it is known to all（很明顯,這是一個頭重腳輕的句子）】
二、語言點
devote one’s life to 把生命/一生獻給…
survive繼續(xù)生存; 幸免于; 經(jīng)受得住
it is known to all眾所周知
三、翻譯：一個明顯的原因是,眾所周知,由于現(xiàn)在占優(yōu)勢的行業(yè)是環(huán)保行業(yè)和高科技行業(yè),因此退休工人曾經(jīng)把自己的一生獻給了當今世界不能繼續(xù)存在下去的落伍行業(yè).
