Period3learningaboutlanguage派生法(derivation)是英语主要的构词法。这方法是借前缀或后缀之助,制造出派生词(derivativewords),主要有名词、形容词和动词三种。前缀以否定前缀(negativeprefixes)un-,in-,im-,il-,ir-,non-,dis-,mis-,mal-等为主,使延伸出来的派生词变成反义词。Ⅰ名词派生词Balance→imbalance;pleasure→displeasure;management→mismanagement;efficiency→inefficiency;concern→unconcern;literacy→illiteracy;resolution→irresolution;interference→noninterference;nutrition→malnutrition.Ⅱ形容词派生词Accurate→inaccurate;patient→impatient.regular→irregular;legal→illegal;native→non-native;orderly→disorderly;common→uncommon.Ⅲ动词派生词Agree→disagree;judge→misjudge;treat→maltreat;activate→inactivate;use→ill-use;mobilize→immobilize;manage→mismanage;quote→unquote.除了否定前缀之外,其他常用的前缀还有anti-,auto-,bi-,co-,counter-,de-,ex-,inter-,mono-,post,pre-,pro-,re-,sub-,super-,trans-,tri-,ultra-等。名词或动词加上适当的后缀,便可以得到形容词派生词,如:commerce→commercial;depend→dependent.名词或形容词加上动词性的后缀,可以得到动词派生词,加上副词性后缀(仅限-ly),则得到副词派生词,如:fright(名词)→frighten(动词); modern(形容词)→modernize(动词); beauty(名词)→beautify(动词); year(名词)→yearly(副词); quick(形容词)→quickly(副词)。1.Usethecorrectprefixorsuffixforeachword.2.Choosethecorrectwordtofillineachoftheseblanks.3.Completethefollowingpassagewiththewordsandphrasesbelowinthecorrectform.4.Inpairsdividetheseadjectivesintotwogroups:emotionalwordsandcalmwords.Grammar主语从句: 做主语用的名词性从句,因其在复合句中做主语,又称主语从句,引导主语从句的有连词that,whether,连接代词who,what,which,连接副词when,where,how,why等。 1.连接词:2)连接代词who,what,which,whatever,whichever,whoever3)连接副词when,where,how,why等。2)It+不及物动词+主语从句 Itseemed(happened,doesn’tmatter,hasturnedout)that…3)It+及物动词(被动语态)+主语从句误:Theyshouldlikeeachotherisnatural. 正:Thattheyshouldlikeeachotheris natural. 正:Itisnaturalthattheyshouldlike eachother.1.Ihavealwaysbeenhonestandstraightforward,anditdoesn‘tmatter______thatI’mtalkingto.(2004年广东省卷) A.whoisitB.whoitis C.itiswhoD.itiswhom2.Itisprettywellunderstood___controlstheflowofcarbondioxideinandouttheatmospheretoday.(2003上海)A.thatB.whenC.whatD.how3._____madetheschoolproudwas______morethan90%ofthestudentshadbeenadmittedtokeyuniversities.(2003上海春季) A.What
