【文章內(nèi)容簡介】 considered to be → was it would seem that → seemingly ? 7. 摘要中盡量避免使用第一人稱 we， I為主語。 . In this paper, we discuss the application conditions of this method → The application conditions of this method are discussed. 摘要的時(shí)態(tài) ? 一般現(xiàn)在時(shí)（主要時(shí)態(tài)） ? 一般過去時(shí) ? 現(xiàn)在完成時(shí) 一般現(xiàn)在時(shí) ? 敘述研究方法和目的 Example： This article sets out four of the main misconceptions, discusses why they have arisen, and why they can be so described. ? 介紹研究背景中不受時(shí)間影響的普遍事實(shí)。 Example Coffee has several metabolic effects that could reduce the risk of gallstone 形成的代謝作用。 ? 報(bào)道研究結(jié)果 Example： The results show that the period of induction and the patent period of stressor can be initially confirmed by the electrical conductivity of medium and the variability of soluble protein in tomato. ? 陳述結(jié)論，提出建議或是描述一般規(guī)律 Example： In doing this, the article attempts to define some important characteristics of municative language teaching as it is practiced at present. 一般過去時(shí) ? 介紹研究過程： Example： In order to separate and extract the substance, tomato was firstly cultured in totally nutrient solution, then shifted to the inpletely nutrient solution till the period of 3 leaves and core. 現(xiàn)在完成時(shí) ? 描述已做過的工作，以表達(dá)延續(xù)性 Example： Man has not yet discovered an effective cure for the mon cold.（人類至今尚未發(fā)現(xiàn)一種有效治療感冒的方法。） ? 介紹研究背景中某種研究動(dòng)向 Example： The patients have been followed for 15 to 32 years since the beginning of their disease. EI 數(shù)據(jù)庫建議 用過去時(shí)態(tài)敘述作者工作； 用現(xiàn)在時(shí)態(tài)敘述作者結(jié)論 。 靈活選用不同時(shí)態(tài) ? 原則： 以基本時(shí)態(tài)為基礎(chǔ)（一般現(xiàn)在時(shí)和一般過去時(shí)），根據(jù)句子需要選用 Example： However, little has been done on how to make the operation schedules after the job sequences have been determined. 摘要的語態(tài) 目前 ， 英文摘要仍以被動(dòng)語態(tài)具多 ， 這種語態(tài)“ 可以在主語部分集中較多的信息 ， 起到信息前置 ， 語義鮮明突出的效果 。 ” 主動(dòng)語態(tài)有增長的趨勢，認(rèn)為“主動(dòng)語態(tài)表達(dá)的語句文字清晰、簡捷明快，表現(xiàn)力強(qiáng)，動(dòng)作的執(zhí)行者和動(dòng)作的承受者一目了然，往往那給人一種干凈利落、涇渭分明的感覺?！? 摘要中的語法修辭 (1) 力求簡捷 at a temperature of 250℃ to 300℃ → at 250 to 300℃ at a high pressure of 2 kPa → at 2 kPa has been found to increase → increased from the experimental results, it can be concluded that → the results show (2) 能用名詞作定語的不用動(dòng)名詞作定語 ， 那用形容詞作定語的不用名詞作定語 measuring accuracy →measurement accuracy experiment results →experimental results (3) 可直接用名詞或名詞短語作定語的情況下 ， 要少用 of句型 accuracy of measurement → measurement accuracy structure of crystal → crystal structure (4) 可用動(dòng)詞的情況盡量避免用動(dòng)詞的名詞形式 Measurement of thickness of plastic sheet was made ↓ Thickness of plastic sheet was measured (5) 一個(gè)名詞不宜用多個(gè)前置形容詞來修飾 ， 可改用復(fù)合詞 ， 兼用后置定語 thermal oxidation apparent activation energy ↓ apparent active energy of thermooxidation (熱氧化的表面活性能量 ) Exercise ? A detailed study of the melting behavior of oriented isotactic polypropylene has been carried out using differential scanning calorimetry. (用 DSC 研究聚丙烯的熔融行為 ) The orientation in isotactic polypropylene was produced ? by extruding it in solid phase(固體拉伸取向 ). At extrusion ratio (ER ) greater four, two melting peaks were observed. With increasing ER, the lower temperature peak was found to shift to higher temperature. The corresponding shift in the higher temperature peak was much less (兩個(gè)熔融峰及其隨拉伸比的變化 ). It is shown that these peaks originate in the melting of crystalline species having different degrees of crystal disorder and stereoblock character(存在不同晶體 ). 此例回答了如下四個(gè)問題： 回
