will

bemorepollution.将会有更多的污染。

Therewillbe...句型是Therebe句型的一般将来时形式,表示对未来存在某物

的描述。如:♦Therewillbemorepeopleinthefuture.未来将有更多的人。

过教材·学优Therewillbe...=Thereisgoingtobe...后者更倾向于已经有预兆,或者有计

划。如:♦Thereisgoingtobeaconcerttomorrownight.明晚将有一场音乐会。

Therebe句型的一般过去时形式为Therewas或Therewere;现在完成时形式

为Therehavebeen或Therehasbeen。2.theenvironmentwillbe

in

great

danger.……环境将处于极大的危险中。beindanger表示处于危险状态。be动词随主语和时态的变化而变化。如:♦Thesharksareindangertheseyears.这些年,鲨鱼处于危险中。

bein+n.表示“处于……状态”。beinneed表示“处于所需要的状态”。

bein+n.有时可以表示一个副词的意思。如:beinsurprise=surprisedly。3.Everyoneshouldplay

a

part

insavingtheearth.人人都应该参与拯救地球。playapartin...在……当中扮演重要角色或发挥重要作用。如:♦Heplayedanimportantpartinthisactivity.他在此次活动中扮演着重要的角色。

与part相关的短语还有:takepartin...参加……;partwith...放弃……。

表示“在……中发挥重要作用或对……产生影响”的短语还有:playarole

in...;makeadifferenceto...;haveaninfluenceon...。4.—Thisringlooks

nice.Is

made

inThailand.——这枚戒指看起来很漂亮,它是银制的吗?——是的。并且是泰国制造

的。

bemadeof...用……制成(成品能看出原材料)Thedeskismadeofwood.这张桌子是用木头制成的。bemadefrom...用……制成(成品看不出原材料)Paperismadeofwood.纸张是用木头制成的。bemadein/at...在……地方被制成ThemobilephoneismadeinChina.这款手机是中国制造的。

与make相关的其他短语:makemistakes犯错误;makeupone'smindtodo下

定决心去做;makeprogress取得进步;makeplans制订计划;makeadecision做

决定;makeachoice做出选择;makeanoise制造噪音。

除make以外,表示制作的单词还有produce,produce更倾向于正式的规模生

产。如:♦SilkismostlyproducedinJiangsuProvince.丝绸主要是在江苏生产的。5....Americanscanhardlyavoid

buyingproductsmadeinChina.……美国人很难避免买到中国制造的产品。

avoidsth./doingsth.避免某事/做某事。如:♦Hecheckedhispaperonceagaintoavoidanymistakes.他又一次检查了试卷以避免错误。♦Igotupearlytoavoidbeinglateforschool.我早早起床,以免上学迟到。

主动语态的see...as...表示“将……视为……”。如:♦Iseehimasoneofmyfamily.我视他为我的家人之一。辨析look,see,read与watchlook是不及物动词,强调“看”的动作,接宾语时,后加at;see强调“看”的结果,表示看见,可以直接加宾语;read通常用来表达看书、报、杂志、信等文字性内容;watch意为“观看,注视”,强调长时间观看运动着的事物或影像。8.InEngland,teadidn'tappearuntilaround1660...在英国,茶直到大约1660年才出现……

until的同义词为till,用法相似。9.ThetelephonewasinventedbyAlexanderGrahamBell.电话是由亚历山大·格拉汉姆·贝尔发明的。

invent是及物动词,意为“发明”,也是科技文体中常见的动词。sb.inventsth.

意为“某人发明了某物”。如:♦CarlBenzinventedthecar.卡尔·奔驰发明了汽车。inventorn.发明者inventionn.发明♦EdisonisoneofthegreatestinventorsinAmericanhistory.爱迪生是美国历史上最伟大的发明家之一。♦Therehavebeenmanygreatinventionsinthetwenty-firstcentury.在21世纪已有很多伟大的发明。

discover意为“发现”,discover的对象是一直存在的,未被人们认识或发现的

东西。invent意为“发明”,invent的对象是之前没有的,被创造出来的。10.It

is

believed

thatthefirstbasketballgameinhistorywasplayedonDecember

21,1891.人们公认历史上的第一场篮球赛是在1891年12月21日进行的。

采用被动语态表达的短语还有:Itissaidthat...据说……;Itisknownthat...人们

都知道……。一、英语学科素养随着科学技术的发展,科技英语已经深入到我们生活中的很多方面。我

省在中考试题中也多次采用科技题材类文章。科技英语无论在语法结构还

是词汇方面都形成了它特有的习惯用法、特点和规律。科技英语除了具有

和普通英语相同的共性之外,又具有其个性。科技语言的总的要求是以最少

的文字符号准确地表达、传递最大的信息量。为此,语言精练、结构紧凑就

成了科技语言的突出特征。由于科技文章反映科学家的思考和工作方法。科技英语的特点包括:针对性(文章紧扣主题)、简洁性(结构紧凑,用词简洁明写话题·文优了)、连贯性(术语数字的引证具有前后一致性)、精确性、合理安排(科技文

章中表达的信息、观点和思想要符合逻辑顺序)、直观手段(科技文章常附

有各种表格、图表、公式和符号来说明或论证问题,无需用文字再说明)等。基于上述特点,掌握科技类英语文本的阅读有助于培养学生缜密分析、谨慎

逻辑、规范表达语言的思维习惯。二、表达交流共享(一)中考书面表达命题分析

话题类型

科技类话题作文在全国的中考试题中出现的频度较小。主要涉及以下三类:1.科技产品特征、用途的表达2.科技产品对于生活影响的表达3.科技产品未来走势的常用表达(命题示例)网络的发明虽然时间不长,但是已经改变了我们的生活方式。你

校正在举办以“TheInternetHasChangedOurLife”为题的英语征文活动。

请根据信息提示,写一篇英语文章进行投稿。(1)beinventedbytheUSgovernmentinthe1960s(2)bewidelyusedinourdailylife(3)influenceonourlife(4)thefutureofInternet要求:1.包含提示全部信息。2.不能出现与本人相关的任何信息。3.词数110左右。

1.从互联网的历史、用途、对生活的影响以及未来走势等方面进行阐述。

写作时,应注意包含全部内容要点并分段,使文章有逻辑性、连贯性。2.谈及互联网对生活的影响的时候,可以引用过去事例来说明,注意使用与过

去相关的时态。

thinkanddothings.(二)话题核心句型应用

精典句型

1.TheInternetisoneofthemostimportantinventionsinhumanhistory.互联网是人类历史上最重要的发明之一。

oneof+the+形容词最高级+名词复数意为“最……的……之一”。2.Studiesshowthatnearly80percentofthepopulationareusingtheInternetforshopping.研究表明将近有80%的人口在使用互联网购物。

Studiesshowthat...意为“研究表明……”。

Asurveyshowsthat...调查显示……;Accordingtoarecentresearch...根据最近的一项研究……。3.Thelargeemissionofcarbondioxideleadstotheincreasingtemperatureofthe

earth.二氧化碳的大量排放导致了地球气温的升高。

leadto...导致……,后接名词或动名词。

表示前因后果的短语还有resultin...,asaresult,dueto...,becauseof...,thanksto...。4.ThereisnowonderthatChinaenjoysthefastestscientificandtechnological

progress.毫无疑问,中国是科技领域增速最快的国家。

Thereisnowonderthat...表示“肯定/无疑……”。

表示相似意思的还有:Thereisnodoubtthat...,Itiscertainthat...,Itisknownforsurethat...。5.Inaword,theappearanceofmobilephoneshasreallymadeabigdifferencetopeople'slives.总而言之,手机的出现对人们的生活的确产生了很大影响。

inaword常用于结束段落的总结。

用于科技文体结束段落总结的开头短语还有:inconclusion,forthisreason,allinall等。6.Unlikehumans,robotscan'tbecreativeinsomeways,butitcantaketheplace

ofhumansinmanyfields.不像人类一样,机器人在某些方面不如人类有创意,但是它可以在很多领域取

代人类。

使用unlike来形成对比,以突显描写对象的特点。

类似的短语还有comparedwith...,justas...。(三)写作范例详解在近几年的全国中考题中,2017年广州市中考题的书面表达与本话题相关。(2017·广东广州)假如你发明的“飞行单车”在学校科技节中获奖,被推荐参加一个国际

青少年科技展览。请用英语介绍你的发明,内容包括下图中1~4项。注意:(1)参考词汇:轮子wheel太阳能solarpower(2)词数80左右(文章的开头已给出,不计入词数)。(3)不得透露学校、姓名等任何个人信息,否则不予评分。Myinventionisaflyingbike....

审题要素

1.从题目中获悉本文的文体为说明文。考生应按照一定的说明顺序对科技

物品进行描述。2.说明时,要抓住描写对象的特点,分类描述。3.在写改进计划时,要分析目前产品设计还存在的不足之处,充分发挥想象力。4.由题目要求可知本文还含有一定的推荐目的,所以要将青少年科技展的特

点和飞行单车的特点进行有机融合。
