2018考研英語(yǔ)：本族語(yǔ)言

We are obliged to them because some of theselanguages have since vanished, as the peoples whospoke them died out or became assimilated andlost their native languages.
    譯文：我們很感激他們，因?yàn)樵诖酥?，由于說這些語(yǔ)言的部族或是滅絕，或是被同化并喪失了自己的本族語(yǔ)言，這些語(yǔ)言中有一些已經(jīng)消失了。
    點(diǎn)睛：本句的主干為we are obliged to them+ because引導(dǎo)的原因狀語(yǔ)從句，該原因狀語(yǔ)從句中還包含由as引導(dǎo)的另一個(gè)原因狀語(yǔ)從句。who引導(dǎo)的是以peoples為先行詞的定語(yǔ)從句。短語(yǔ)be obliged( to sb.) for sth. /doing sth.意為“受恩惠而感激(某人)”。die out此處意為“滅絕，逐漸消失”。
    考點(diǎn)歸納：與動(dòng)詞die相關(guān)的常見短語(yǔ)還有：
    *die away慢慢變?nèi)?，漸漸消失
    The strange noise died away.
    那奇怪的噪音慢慢消失了。
    *die down減弱，平息
    Don’t worry; the gossip will soon die down.
    別擔(dān)心，流言不久就會(huì)平息的。
    *die off相繼死去
    The plants in the garden died off.
    花園里的植物相繼死去。
