初中语法之介词教学内容:介词教学目标:(1)掌握介词的定义和用法。(2)掌握常用的介词短语。教学重难点:介词的用法及重要介词短语。教学过程:Step1:介词又叫前置词,是一种虚词。介词是一种用来表示词与词,或者词与句之间的关系的词,在句中不能单独作句子成分。介词一定要有宾语,充当宾语的一般有名词、代词或相当于名词的其它词、短语或句子。介词一般可以分为三种,一种是简单介词,如at,in,on,beside,to,for等;另一种是短语介词,即由两个以上的词组组成的短语,如infrontof,becauseof,outof,insteadof等;还有一种叫二重介词,如untilafter,frombehind等。(一)介词的句法功能介词不能独立在句中做成份,介词后必须与名词、代词、或动名词构成介词短语在句中充当一个成份,表示人、物、事件等与其它人、物、事件等之间的关系。1、作定语:Thebookonthetableismine.2、作状语:Wehavebreakfastatseven.(表时间);Theywerelateformeetingbecauseoftheheavyrain.(表原因);Theystartedthemachinebypressingthebutton.(表方法)3、作表语:Mydictionaryisinthebag.4、作宾语补足语:Ifoundhimintheoffice.(二)主要介词区别1、表示时间的at,in,on:at表示片刻的时间,如:at8o’clock,常用词组有:atnoon,atnight,atmidnight,attheendof,atthattime,atthebeginningof,attheageof,atChristmas,atNewYear等。in表示一段的时间,如:inthemorning,intheafternoon,intheevening,inOctober,in1998,insummer,inthepast,inthefuture等。on总是跟日子有关,onMonday,onChristmasmorning,onthefollowing,onMayDay,onawarmmorning等。2、表示时间的since和from:since表示从过去到现在的一段时间的过程,常与现在完成时连用。from表示从时间的某一点开始,不涉及与现在的关系。一般多与现在时、过去时、将来时连用。如:Ihopetodomorningexercisesfromtoday./Wehavenotseeneachothersince1995.3、表示时间的in和after:两者都表示“在(某个时间)之后,区别在于in表示“在(一段时间)之后”,而after则表示“在(某一具体时间点之后)”,in短语和将来时态连用,after短语和过去时态或将来时态连用。如:We’llbebackinthreedays./Afterseventherainbegantofall./Whatshallwedoaftergraduation?注意:after有时也可以表示在一段时间之后(常用在过去时里)。如:Aftertwomonthshereturned.4、表示地理位置的in,on,12\nto:in表示在某范围内,on指与什么毗邻,to指在某环境范围之外。如:ChangchunisinthenortheastofChina./MongoliaisonthenorthofChina./JapanistotheeastofChina.5、表示“在……上”的on和in:on只表示在某物的表面上,而用in表示占去某物一部分。如:Thereisabookonthepieceofpaper./Thereisaninterestingarticleinthenewspaper./Hedugaholeinthewall.6、表示“穿过……”的through和across:through表示从内部通过,与in有关;across则表示从一端至另一端在表面上的通过,与on有关。如:Waterflowsthroughthepipe./Theoldmanwalkedacrossthestreet.7、inthecorner,onthecorner,atthecorner:inthecorner表示在角落里,in指角的内面;onthecorner表示“在角上”,on指的不是内面,也不是外面,而含内外兼有之意;atthecorner指“在拐角处”,at指的是拐角外附近的外面。如:Thelampstandsinthecorneroftheroom./Imetwithhimatthestreetcorner./Hesatonthecornerofthetable.8、intheend,attheendof,bytheendof:intheend作“最后”、“终于”解,可单独使用,后不接介词of;attheendof表示“在……末梢”,“到……尽头”,既可指时间,也可以指地上或物体。不可单独使用;bytheendof作“在……结束时”,“到……末为止”解,只能指时间。不可单独使用。如:Intheendtheyreachedaplaceofsafety./Attheendoftheroadstandsabeautifulgarden./TheydecidedtohaveanEnglisheveningattheendofthisweek./bytheendoflastmonthhehadfinishedthenovel.9、表示“关于”的about和on:两者都有“关于”的意思,不过前者为一般用词,而后者为较正式的“论述”。如:Hecametotellmeaboutsomethingimportant./Hewroteabookonscience.10、between,among:一般说来,between表示两者之间,among用于三者或三者以上的中间。如:Youaretositbetweenyourfatherandme./Heisalwayshappyamonghisclassmates.注意:但有时说的虽然是三个以上的人或东西,如果强调的是两两相互间接关系,适用于between。如:Agreementsweremadebetweenthedifferentcountries.在谈到一些事物或一组事物,而把它们视为分居两边时用between。如:Thelittlevalleyliesbetweenhighmountains.。在谈事物间的差别时,总是用between。如:Theydon’tknowthedifferencebetweenwheat,oatsandbarley.11、besides,except,but,exceptfor:besides指“除了……还有,再加上”。如:Allwentoutbesidesme.;except指“除了,减去什么”,不能放在句首。如:Allwentoutexceptme.;but与except意思近似,表示“除了……外”经常用在no,all,nobody,anywhere,everything等和其他疑问词后面。如:Ineversawhimreadinganythingbutthenewspaper.;exceptfor表示“如无……就,只是”表明理由细节。如:Hisdiaryisgoodexceptforafewspellingmistakes.。12、表示“用”的in和with:表示工具的“用”,用with,而表示材料、方式、方法、度量、单位、语言、声音等的“用”,用in。如:Heiswritingaletterwithapen./Hewrotetheletterinpencil./Wemeasureditinpounds./Readthetextinaloudvoice./TellmethestoryinEnglish.13、inchargeof和inthechargeof:两者都表示“由谁负责、照顾、管理”。区别在于:inchargeof后接被照管的人或物,而inthecharge12\nof后面则跟照管的人。如:Whoisinchargeoftheproject?/Theprojectisinthechargeofanengineer.。14、as,like:as作“作为”、“以……地位或身份”解。如:Letmespeaktoyouasafather.(事实是父亲);like作“象……一样”解。如:Letmespeaktoyoulikeafather.(事实上不是父亲)。15、infrontof和inthefrontof:infrontof=before,是“在……前面”的意思(不在某物内);inthefrontof则是“在……前部”的意思(在某物内)。如:Thereisadeskinfrontoftheblackboard./Theboysatinthefrontofthecar.。16、in,into:into表示动向,不表示目的地或位置。如:Wewalkedintothepark.;in通常表示位置。如:Wewalkedinthepark;in和drop,fall,put,throw,break等终止性动词连用时,也可以表示动向。如:Ihaveputthecoinin(into)mypocket.我把硬币放进衣袋。17,on,above,over:这三个介词都可以表示地点,意思是“在……上”,但具体含义有所不同。⑴on是指与物体表面接触而不是在其上方。例如:Theyaresittingonthegrass. 他们坐在草地上。Doyouliveonthesecondfloor? [美国英语]你住在二楼吗?/[英国英语]你住在三楼吗?Hejumpedonthehorse. 他跳上了马。⑵above是指离开物体表面而在其上方,其反义词为below。例如:Theplaneflewabovetheclouds.飞机在云层之上飞行。Themountainisabout2,000metresabovethesea. 那座山约海拔2,000米高。⑶over是指在物体的正上方,有时还有“覆盖;越过”之意,其反义词为under。例如:Alampwashangingoverthetable.一盏灯高挂在餐桌上方。Isawastonebridgeovertheriver.
