科技論文中大量使用各學(xué)科專門術(shù)語(yǔ)，還經(jīng)常使用一些日常語(yǔ)言中不怎么使用書面詞匯，主要是突出科技英語(yǔ)正式、莊嚴(yán)語(yǔ)體特性，同時(shí)應(yīng)避免使用浮華、帶有感情色彩詞語(yǔ)，當(dāng)然并不是說(shuō)科技論文中不使用普通詞匯。另外，一些動(dòng)詞短語(yǔ)往往由正式動(dòng)詞替換，以求簡(jiǎn)練。第38頁(yè)第38頁(yè)科技論文寫作中詞匯普通英語(yǔ)詞匯

thatitcanmeasuretheslightchangeinpressure.（2）采用“主…謂…賓”句型代替漢語(yǔ)中“主…系…表”句型。撰寫論文時(shí)受漢語(yǔ)影響，很不習(xí)慣使用這種結(jié)構(gòu)。第50頁(yè)第50頁(yè)經(jīng)常使用一些句子表示方式“Have”句型

即句中謂語(yǔ)動(dòng)詞為have。凡在漢語(yǔ)句中似乎找不到動(dòng)詞普通可使用這一句型，它主要用于表示尺寸、大小、比較、優(yōu)缺點(diǎn)等概念。A.表示尺寸、大小、長(zhǎng)度、高度“Something+have+a(an)+表示大小名詞+of+數(shù)量”Thewallofthereactorhasathicknessof1centimeter.Thispipehasanapproximatelengthof50meters.第51頁(yè)第51頁(yè)經(jīng)常使用一些句子表示方式B.表示比較“somethingA+have+比較級(jí)（或as+形容詞原級(jí)）+要比較名詞+than+somethingB”Thissubstancehasamorecomplicatedchemicalstructurethanthatone.Alcoholdoesnothaveashighaboilingpointaswater(does).第52頁(yè)第52頁(yè)經(jīng)常使用一些句子表示方式C.表示優(yōu)缺點(diǎn) “主語(yǔ)+have+優(yōu)缺點(diǎn)名詞”Thereactorhastheadvantagesofsimplestructureandhighefficiency.Thethree-phaseslurryreactorhasthedisadvantageofitsheight.第53頁(yè)第53頁(yè)經(jīng)常使用一些句子表示方式（3）采用BE句型。這一句型我們也不是十分熟悉。A.表示大小、數(shù)量

Something+be+數(shù)量+表示大小形容詞（或in+表示大小名詞）Thedistillationcolumnis20metershigh.（或inheight）Theseperforatedplatesare2centimetersthick.

當(dāng)然依據(jù)語(yǔ)法條文，也可寫成下列句型，中國(guó)人尤其習(xí)慣這一句型。Theheightofthedistillationcolumnis20meters.第54頁(yè)第54頁(yè)經(jīng)常使用一些句子表示方式B.表示比較物A+be+比較級(jí)（或as+原級(jí)）+in+要比較對(duì)象+than(as)+物BThissubstanceismorecomplicatedinchemicalstructurethanthatone.Alcoholisnotashighinboilingpointaswater(is).中國(guó)人習(xí)慣Thechemicalstructureofthissubstanceismorecomplicatedthanthatofthatsubstance第55頁(yè)第55頁(yè)經(jīng)常使用一些句子表示方式(4)不少情況下使用靜態(tài)結(jié)構(gòu)來(lái)表示狀態(tài)、特性、情況以取代采用行為或過(guò)程句法結(jié)構(gòu)。

使用“系動(dòng)詞+表語(yǔ)”結(jié)構(gòu)。表語(yǔ)普通是形容詞，有時(shí)也可是名詞或介詞短語(yǔ)。Theflaskisbreakable

=Acomparisonofexperimentaldata…第60頁(yè)第60頁(yè)經(jīng)常使用一些句子表示方式(6)限定性短語(yǔ)或從句 按照傳統(tǒng)語(yǔ)法，當(dāng)你希望從一組事物中，把其中一個(gè)(一部分)尤其區(qū)分出釆，以“限定說(shuō)明”其與其它部分不同之處時(shí)，要采取“that”(而不是”which”)，也就是說(shuō)，that引出是實(shí)質(zhì)性信息。這個(gè)短語(yǔ)或從句就成了主句或句子必需成份，它們是限定性短語(yǔ)或從句。沒(méi)有這個(gè)短語(yǔ)或從句，主句或句子就失去了基本含義。第61頁(yè)第61頁(yè)經(jīng)常使用一些句子表示方式Comparisonwillberestrictedtoacetylenecompoundsthat(不用which)havethesamefunctionalendgroups.ReactionleadingtothedesiredproductsareshowninScheme1.(7)非限定性短語(yǔ)或從句 當(dāng)一個(gè)短語(yǔ)或從句即使能傳達(dá)信息，但并不是主要．而只是附加信息，那么它們稱為非限定性短語(yǔ)或從句。也就是，當(dāng)它們被刪除時(shí)，主句沒(méi)有失去其主線含義。非限定性從句引入采用“which”，非限定性短語(yǔ)和從句與句子其它部分用逗號(hào)隔開。第62頁(yè)第62頁(yè)經(jīng)常使用一些句子表示方式Allthechemicals
