【正文】 由于翻譯過程是個創(chuàng)造性的、從生疏到熟練的過程，只有具備刻苦的精神、嚴肅認真的學習態(tài)度和一定的英語水平、專業(yè)水平和漢語表達水平，才能充分理解原專業(yè)文獻的含義，把握原文的想要表述的實質(zhì)內(nèi)容，運用種種表達手段和翻譯技巧，用準確流暢的符合漢語言習慣的語言生動地再現(xiàn)原文。而興趣不是與生俱來的，需要培養(yǎng)。而學生要想擴大詞匯量，就必須在閱讀的同時進行識記，并擴大閱讀范圍。也有學生反映，專業(yè)英語學完以后，英語和專業(yè)兩方面都有所鞏固和加強，所以學生要做的仍舊是樹立信心，保持良好積極的心態(tài)。二、大學生學好機械專業(yè)英語的方法必須將機械專業(yè)知識與英語知識相結合。其實，隨著社會的發(fā)展，各種工作崗位對人才的要求越來越高，即使作為一名操作工，也有很大可能要面對純英文的說明書、加工圖紙等專業(yè)文獻，更無須說將來擔任管理和領導崗位對專業(yè)英語的需求了。Rivers in such a condition，which unfortunately can be found near densely polluted areas all over the world，support no fish，are high in bacterial content（usually includingpathogenic organisms），appear muddily bluegreen from choking algae，and，in extreme cases，stink from putrefaction and fermentation。The river then begins to repurify itself。The fish begin to die，but it is not the sewage that is killing them。Now follow the water downstream from “Polutionville.” There processes are going on, all at the same bacteria are feasting on the of this action，the amount of sewage in the water is decreasing，so the BOD is going down。四、課文填空：UNIT13的第一部分（Pollution of streams and rivers）PoHution of Streams and RiversWhen sewage is discharged into a freshwater stream，the stream bees pollution。T美國最大的電話電信公司3)CFC=chlorofluoro carbon 含氯氟烴4)Sloppy housekeeping practices such as leaking tanks，valves，or pumps may cause process chemicals to spill requiring cleanup and ，例如儲罐、閥門或泵的泄漏，都會導致工藝過程中化學品的濺漏而需要采取凈化和處理措施。4）theories,and in particular,mathematical theories,often enable us to bridge the gap between experimentally controlled observations and observations made in the ，尤其是數(shù)學理論，通常使我們可以彌補（縮?。嶒炦^程觀察的結果與該領域理論推導的結果間的差距。 and carbohydrates constitute 90 percent of the organic matter in domestic 。 Reduction/Waste Minimization Techniques廢物回收/廢物最少化技術(包括以下幾點)●product changes產(chǎn)品改變 ●process changes過程改變●equipment modifications設備改造 ●operating practices操作訓練●recycling and reuse回收和再利用 is air pollution?
