構(gòu)詞法1.合成法將兩個或兩個以上獨立且語義不同的單詞合在一起構(gòu)成新詞(xīncí)的方法叫做合成法。合成法是一種比較靈活的構(gòu)詞方法，可以合成名詞、形容詞、副詞、代詞、動詞等。例如：afternoon,sportsman,blackboard,sportsperson,newspaper,airplane,classmate,grandfather等就是通過合成構(gòu)詞法構(gòu)成的名詞；kind-hearted,middle-aged,hard-working等為合成形容詞；however,maybe,himself,everyone,nothing,overlook等也都是通過合成法構(gòu)成的單詞。第五頁，共21頁。第五頁，共212.派生(pàishēng)法通過在詞根前面加前綴或在詞根后面加后綴構(gòu)成(gòuchéng)一個新詞的方法叫作派生法。要通過派生法理解和記憶單詞,我們需要掌握常見的前綴和后綴及派生規(guī)律。第六頁，共21頁。2.派生(pàishēng)法通過在詞根前前綴含義例詞dis-不disagree,dislikeen-使……處于某種狀態(tài)enable,enrichim-,in-不Impossible,impatient,inexpensiveinter-在……之間；相互international,interconnectmis-錯誤地mislead,misunderstandnon-不,非non-smoker,non-nativere-再,重復(fù)rewrite,retellun-不unable,unhappy,unpopular常見(chánɡjiàn)前綴第七頁，共21頁。前綴含義例詞dis-不disagree,dislikeenworkout解決(jiějué)；計算；產(chǎn)生結(jié)果；設(shè)計出這里的go為系動詞。英語系動詞的功能主要是把表語和主語聯(lián)系在一起，說明主語的屬性、特征或狀態(tài)。系動詞不能在句中獨立(dúlì)作謂語，必須和后面的表語一起構(gòu)成句子的謂語。第八頁，共21頁。workout解決(jiějué)；計算；產(chǎn)生結(jié)果；設(shè)計出某些含有變化意義的動態(tài)系動詞如get,become,grow,turn等的進行時態(tài)可與形容詞的比較級連用(liányòng)，表示漸進過程，其意思是“越來越……”。eg：Heisgrowingtallerandtaller.他長得越來越高了。Ourlifeisgettingbetterandbetter.我們的生活越來越好了。第九頁，共21頁。某些含有變化意義的動態(tài)系動詞如get,become,gget“變得”，在口語中用得很多。become“變成，成為(好壞情況均可)”。后接形容詞、名詞、過去分詞作表語。go“變得(某種由好到壞的情況)”，可表示顏色的變化或語態(tài)的變化。turn“變成”，強調(diào)與原來不同的、新的變化，如變質(zhì)、變色等。grow“逐漸變得……”，強調(diào)其變化過程。易混系動詞(dòngcí)的區(qū)別get,become,go,turn,grow“變得”第十頁，共21頁。get“變得”，在口語中用得很多。become“變成，成為(carefor與careabout的意義(yìyì)、用法區(qū)別careabout在乎，關(guān)心Idon'tcareaboutyouropinion.我不在乎你的意見。Don'tyoucareaboutanybody?你難道誰也不關(guān)心嗎？第十一頁，共21頁。carefor與careabout的意義(yìyì)、用carefor喜歡，照顧Shedoesn'tcareforthatcolour.她不喜歡那種顏色。Hecaredforhissickmotherdayandnight.他日夜照顧生病的母親。第十二頁，共21頁。care喜歡，照顧Shedoesn'tcareforCompletethesentenceswiththewordsinthebox.hopefulimpossiblereuseunhealthywasteful1.Pollutedwateris____________.2.Itis_________tothrowsomuchfoodaway.3.Ifyoulookafterthingswell,youmay________someofthemlater.4.Itis___________tocleanupthewholeriverinsuchashorttime.5.Ifwepayattentiontopollutionnow,thefuturewillbe__________.第十三頁，共21頁。CompletethesentencNounVerbAdjectiveAdverbuseful/uselesshopehopefully/hopelesslypollution——water————waste————usually/unusuallyCompletethetable.第十四頁，共21頁。Completethetable.第十四頁，共21頁。WorkinpairsLookatthepicturesandanswerthequestions.1.Whatkindsofthingscanberecycled?2.Howcanthesethingsbereused?3.Howdoesthishelptheenvironment?4.Haveyoueverrecycledorusedthingsthatcanberecycled?How?第十五頁，共21頁。Workinpairs第十五頁，共21頁。Completetheconversationwiththecorrectformoftheexpressionsinthebox.
