被動(dòng)語(yǔ)態(tài)的翻譯

被動(dòng)語(yǔ)態(tài)的翻譯被動(dòng)語(yǔ)態(tài)廣泛地出現(xiàn)在科技英語(yǔ)中，主要取決于如下情況。1)不必或無(wú)法說(shuō)出主動(dòng)者。Thebook

beentranslated

intomanylanguages.該書(shū)已譯成好幾種語(yǔ)言。Foralongtimealuminium

hasbeenthought

asaneffectivematerialforpreventingmetalcorrosion.長(zhǎng)期以來(lái)，鋁被當(dāng)作一種有效地防止金屬腐蝕的材料。

2)強(qiáng)調(diào)行為對(duì)象，而非行為者，將行為對(duì)象作為句子的主語(yǔ)。Theworkmust

befinished

atonce.該項(xiàng)工作必須馬上完成。Threemachinescan

becontrolled

byasingleoperation.三臺(tái)機(jī)器能由一個(gè)操作者操縱。

3)為了更好地連接上下文。

石油埋藏于地層深處。因此，僅靠研究地層表面，無(wú)法確定有無(wú)石油，必須勘探地下的巖層結(jié)構(gòu)。如果確定某一區(qū)域的巖石層藏有石油，就在該處安裝鉆機(jī)。它的主要部件是機(jī)架，用以撐架一節(jié)一節(jié)的鋼管，讓其下到孔井。一邊鉆井，一邊下鋼管，以防孔壁坍塌。一旦出油，就緊固管蓋，讓油從各個(gè)閥門(mén)噴出。Alongmetalbarisfixedinaresortstandbyoneend.Theotherendisheatedinaflameuntilitbecomesred.Thebarandthestand
