漢語(yǔ)中的主語(yǔ)經(jīng)常省略，英語(yǔ)的主語(yǔ)不能省略。有人見(jiàn)到無(wú)主句就不加區(qū)分地翻譯為英語(yǔ)的被動(dòng)句。當(dāng)然，許多情況下翻譯為主動(dòng)語(yǔ)態(tài)或被動(dòng)語(yǔ)態(tài)對(duì)意思的傳達(dá)不產(chǎn)生實(shí)質(zhì)性影響，但根據(jù)我們對(duì)簡(jiǎn)明英語(yǔ)的學(xué)習(xí)，主動(dòng)語(yǔ)態(tài)在文體上更直截了當(dāng)。 

例1.

依法加強(qiáng)采供血機(jī)構(gòu)建設(shè)，健全采供血機(jī)構(gòu)網(wǎng)絡(luò)；節(jié)約血液資源，做到合理、科學(xué)用血。建立健全省級(jí)血液中心。

到2002年底前，要對(duì)不符合建設(shè)標(biāo)準(zhǔn)的地（市）中心血站進(jìn)行必要的改造。

可以翻譯為被動(dòng)句：

A complete and up-to-standard network of Hood collection and distribution will be created according to law to strengthen institutional capacity. Blood resources will be conserved by using blood rationally and scientifically. Provincial blood centers will be established or improved. By the end of 2002，necessary changes will be made to prefectural and city blood centers that do not meet standards.

但根據(jù)寫(xiě)作的原則，要盡量使用主動(dòng)語(yǔ)態(tài)，所以可以增加主語(yǔ)，翻譯為主動(dòng)句：

We will strengthen the institutional capacity in accordance with the law by creating a complete and up-to-standard network of blood collection and distribution. We will conserve blood resources by using blood rationally and scientifically. We will establish or improve provincial blood centers. By the end of 2002，we will make the necessary changes to prefectural and city blood centers that do not meet standards.
