物不受化学物质的污染。有机农场主也运用很多其他方法来使土壤肥沃。他们常常每年变更每一块地的作物种类。例如，他们可能一年在一块地里种玉米或小麦，其次年在那里种豆子。2.种植不同的作物是因为它们把重要的矿物质释放回土壤，使其为下一批作物生长做好打算。有机农场主还种植多种作物，利用不同深度的土壤来帮助保持土壤肥沃。例如，花生长在地面上，但很多其他蔬菜扎根很深。3.运用不同的有机耕作方法的目的是种植好的食物，同时避开对环境或人的健康造成损害。有些人宁愿完全停止在农业中运用人造化学品。4.阻挡他们这样做的缘由是化学农业满意了世界各地对粮食的巨大需求。有机农业远不能满意那样的需求。5.因此，要找到一个合适的解决方案，使人们的餐桌上有足够的食物，同时保持人们和环境尽可能地健康仍旧有很长的路要走。自查语基落实基本知能Ⅰ.核心词汇依据语境写出正确的单词1．the________industry化学工业2．________farming有机耕作3．enjoy________respect受到广泛敬重4．needtimeto________information须要一些时间来消化信息5．Experienceis________forthisjob.对于这个工作，阅历是特别重要的。6．________energy替代能源7．coverall________ofcitylife涵盖城市生活的各个方面8．the________oftheproblem问题的根源9．abottleof________water一瓶矿泉水10．chemical________化学农药Ⅱ.拓展词汇依据语境写出相应的派生词1．①provide________foryou为你供应养分②________food养分食品2．①ata________of30metres在30米深处②takea________breath深深地吸了一口气3．①an________differentmatter一件完全不同的事情②the________village整个村庄Ⅲ.重点短语1．____________相应地；转而；依次；轮番2．____________例如；比如3．____________做笔记4．____________对……造成损害5．____________至于6．____________关注7．____________富于；有丰富的……8．____________免受(影响、损害等)9．____________随着时间的推移10．____________转向有机食品Ⅳ.重点句型1．[句型]现在分词短语作状语[教材]Whydifferentcropsaregrownisbecausetheyputimportantmineralsbackintotheground,________________________________________．种植不同的作物是因为它们把重要的矿物质带回土壤，从而使之相宜于种植下一批作物。2．[句型]状语从句的省略[教材]Thegoalofusingdifferentorganicfarmingmethodsistogrowgoodfood________________________theenvironmentortopeople'shealth.运用不同的有机耕作方法的目的是种植好的粮食，避开损害环境或者人们的健康。3．[句型]that引导的同位语从句[教材]Whatkeepsthemfromdoingsoisthefact________________________________________________________________________．阻挡他们这样做的缘由是化学农业满意了世界各地对粮食的巨大需求。4．[句型]keepsb./sth.＋adj.(宾补)意为“使某人/某物……”[教材]Organicfarmersfocuson________________________andfreeofdiseasethroughnaturalmeans.有机农夫注意通过自然手段保持土壤肥沃和无病害。课堂提升素养探究新知发展语言学问1.(教材P55)Forexample,pesticidescandamagethelandbykillingnotonlyharmfulbacteriaandinsects,butalsohelpfulones.例如，农药不仅可以杀死有害的细菌和昆虫，还可以杀死有益的细菌和昆虫，从而破坏土地。◎句型公式：notonly...but(also)．..不仅……而且……(1)句中“notonly...butalso...”结构意为“不仅……而且……”，其中also可以省略。(2)“notonly/just...but(also)．..”连接的两个并列成分作主语时，谓语动词的人称与数遵循“就近原则”。[佳句]Asweallknow,readingclassicscannotonlyimproveourstudybutalsoenrichoureverydaylife.众所周知，阅读古典文学不仅提高我们的学习，也丰富了我们的日常生活。[练通]——补全句子/单句语法填空①Beijingis________________________________________________________________(不仅是我国的政治中心，而且是我国的经济中心)．②Notonlythestudentsbutalsotheteacher________(be)againsttheplan.[写美]——微写作③它不仅让我们放松，而且给了我们一个更接近大自然的机会。Notonly________________________butitalsogaveusachancetogetclosertonature.2．(教材P55)Thisaffectsthecropsgrownonthelandand,inturn,theanimalsandhumanswhodigestthem.这影响到在土地上种植的作物，进而影响到消化它们的动物和人类。◎inturn相应地；转而；依次；轮番(1)byturns轮番；交替地(2)taketurnstodosth.轮番做某事Itisone'sturntodosth.轮到某人做某事[佳句]Theoryisbasedonpracticeandinturnservespractice.理论以实践为基础，反过来又为实践服务。[练通]——单句语法填空①Hespendstoomuchtimeonmaths,which________turnaffectstheprogressofhisothersubjects.②Whenitwasmyturn________(give)aspeech,Iwastooexcitedtospeak.③Whenmymotherwasill,mybrothertookturns________(take)careofher.[写美]——微写作④一方面，它不仅有助于强身健体，还相应地帮助我们更有效地学习。Foronething,notonlydoesithelptobuildupourhealth,butitalsohelpsus________________________________．◎digestvt.&vi.消化vt.领悟；领悟n．文摘(1)digestfood消化食物digesttheinformation领悟信息(2)amonthlynewsdigest每月新闻摘要[佳句]Youshouldallowalittletimeafteramealforthefoodtodigest.饭后你应当留点时间让食物消化。[练通]——写出下列句中digest的词性和含义⑤Youshouldn'tgoswimminguntilyourfoodhashadachancetodigest.________⑥Digestedrapidlybythebody,sugarprovidesaquickenergysource.________⑦ThemagazineshegavemeisReader'sDigest.________⑧Ittookmealongtimetodigestthetheoryputforwardatthemeeting.________3．(教材P55)Theymaylookbeautifulontheoutside,butinsidethereisusuallymorewaterthanessentialminerals,andtheyoftenhavelessflavouraswell.它们可能外表看起来很美丽，但里面通常有更多的水分，而不是基本的矿物质，而且它们通常也没有那么多的味道。◎essentialadj.完全必要的；极其重要的(1)beessentialto对……不行缺少的(2)Itisessentialforsb.todosth.对某人来说做某事是必要的Itisessentialthat...shoulddosth.做某事是必不行少的[佳句]AsfarasI'mconcerned,moneyisnotessentialtohappiness.就我个人而言，金钱对于华蜜并非必不行少。[写美]——补全句子①有必要把这些申请表尽早寄回。Itisessentialthattheseapplicationforms________________________________________．②丰富多样的文化生活对这对夫妇而言是至关重要的。Arichandvariedculturallife______________thiscouple.4．(教材P55)Asanalternative,somefarmershaveswitchedtoorganicfarming,andmanycustomershaveturnedtoorganicfoodwhentheyshopatthelocalgrocery.作为一种选择，一些农夫转向有机农业，很多顾客在当地杂货店购物时转向有机食品。◎alternativen．可供选择的事物adj.可供替代的；非传统的(1)havenoalternativebuttodosth.别无选择只好做某事analternativeto...……的替代品(2)alternativelyadv.可供选择地[佳句]Ifyoudon'tliketheschoollunch,youhavethealternativeofbringingyourown.要是你不喜爱学校的午餐，你可以自己带饭。[练通]——单句语法填空①Inordertoreducepollution，wehavenoalternativebut________(choose)somecleanresources.②TheInternetalsoprovidesuswithacheapalternativeto________(communicate)withothers.[写美]——词汇升级③FacedwithCOVID-19,wehavenochoicebuttostayathometoalleviatetheserioussituation.→FacedwithCOVID-19,wehaveno________buttostayathometoalleviatetheserioussituation.5．(教材P56)Whydifferentcropsaregrownisbecausetheyputimportantmineralsbackintotheground,makingitreadyforthenextbatchofcrops.种植不同的作物是因为他们把重要的矿物质带回土壤，使其为下一批作物生长做好打算。◎句型公式：现在分词短语作结果状语现在分词短语作
