上海市九年级初三中考英语词性转换知识专练-学案第2页怎样巧解词形变化和词性转换题概述：现代英语任然是词尾变化甚发达的语言，十大词类有六种词主要是以词尾变化而构成词形变化的。它们是名词（数和所有格的变化），代词（格，数，性的变化），形容词和副词（原级，比较级，最高级），动词（三式两分词），数词（基数词，序数词）。这种变化谓之词形变化。词在句中因为担当的成分不同而有不同的词性，它们的拼写也常有变化（如pleasure/pleased/pleasant/please),这种变化谓之词性转换。有些词加上后缀可表示做某种动作的人或工具（invent,inventor)，或表示一种性质，身份，资格等（friend,friendship),加上前缀re--可以表示重新的意思（build/rebuild)，这种变化也称之谓派生。第4页（6)a.ad.形容词转化为副词possible---possiblyprobableprobablyhappy-happilyslow-slowly(7)a.ad.n.形容词转化为副词，名词true--truly--truthlucky--luckily--luck(8)原级比较级最高级far--farther--farthestfar--further--furthestlittle--less--least【解词类题学生必背的词法知识】1）掌握教材中常用词的规则和不规则的词性变化形式；2）知道常见的构词法，会归纳教材中常见词的词性转换，派生词；3）熟记教材中的同根反义词。【解此类题学生必须注意的】1）根据上下文先确定空处应填何种词性的词；第5页2）然后确定该词应作何种词性变化（特别注意同根反义词和缩略形式；3）大写字母。【夯实练习一】一、名词变形容词1.rain__________2.friend____________3.center_____________4.hunger_________5.south___________6.experience_________7.salt__________8.physics___________9.America___________二、形容词变名词1.happy__________2.free____________3.silent____________4.difficult_________5.strong__________6.pleasant__________第6页7.social__________8.kind___________9.long___________三、形容词变副词:1.wonderful_________2.good____________3.usual____________4,bad______________5.willing___________6.immediate________7.bright____________8.angry____________9.warm___________10.terrible___________四、名词变动词:1.courage_________2.advice___________3.practice_________4.lie___________5.ship____________6.face___________7.service_________8.loss___________9.breath__________10.belief__________五、动词变名词:第7页1.decide___________2.produce__________3.translate_________4.enjoy___________5.fail______________6.prepare_________7.discuss__________8.explain___________9.discover_________10.pronounce_________六、名词变形容词变副词:1.fool_________________________2.luck____________________3.success_______________________4.politics___________________5.pride_________________________6.truth____________________7.nature________________________8.care____________________9.bravery_______________________10.comfort___________________七、加前缀re-:第8页1.read___________2.write____________3.tell___________4.view__________5.build____________八、加前缀dis-:1.like_____________2.appear___________3.agree_________4.order____________5.cover___________九、加前缀un-:1.important___________2.necessary__________3.fortunate_________4.able_____________5.fit______________十、加后缀-ful:1.cheer_____________2.hand_____________3.arm____________4.colour____________5.beauty____________第9页十一、加后缀-less:1.help___________2.use_____________3.care____________4.hope____________5.fear_____________中考词性转换归类专练A.1.actv.扮演n.行动；activea.积极的，主动的，活跃的；actorn.男演员actressn.女演员activityn.活动1)________aremoreimportantthanwords.(act)2)JackieChenismyidol.Heisoneofthemostfamous______(act).3)Tosavemoney,usingcoupons（优惠券）becomesoneofthemostpopu...
