九年级上册词形转换
（必考内容+解题技巧+专项练习+答案）
一、专属核心考查内容（对接中考语法填空）
（一）动词变形（分值最高，九上新增三大重难点）
现在完成时（Unit1 核心） 结构 have/has + 过去分词；标志词 since/for/already/yet/so far。重点不规则三态：lead-led-led、bring-brought-brought、find-found-found、write-wrote-written。区分 have been to（去过已回）、have gone to（去了未归）、have been in（待多久）。
被动语态（Unit5 必考） am/is/are done（一般现在被动）、was/were done（一般过去被动）；by 引出动作执行者，词形重点掌握不规则过去分词 produce-produced、invent-invented。
非谓语动词（中考高频搭配） 介词后 doing（look forward to doing、pay attention to doing）；固定搭配 to do（decide to do、refuse to do、encourage sb. to do）；make/let sb. do 原形；stop doing/to do 区分含义。
多级词性转换 v.→n.：create→creation/creator/creativity；pronounce→pronunciation；educate→education/educator；value→value/valuable； v.→adj.（-ed/-ing 辨析）：surprise-surprised/surprising；relax-relaxed/relaxing；人用 - ed，事物用 - ing。
（二）形容词、副词与比较等级（中考必考点）
变形规则：adj.+ly 变副词；辅音 + y 变 i+ly（easy-easily）；le 结尾去 e+y（simple-simply）；特殊 good-well、true-truly。
比较级 / 最高级：单音节 er/est；多音节 more/most；不规则 good-better-best、bad-worse-worst、much-more-most；标志 than 用比较级，one of+the + 最高级 + 名词复数。
成对后缀构词：-ful（有…）/-less（无…）：useful/useless、hopeful/hopeless、helpful/helpless。
（三）名词变形（抽象名词为主，九上特色）
adj.→抽象名词高频后缀： -ent→-ence：convenient→convenience、different→difference； -t→-th：true→truth、wide→width； 形容词加 - ness：happy→happiness、silent→silence、kind→kindness； -able→-ability：able→ability；important→importance。
名词复数不规则：man-men、woman-women、leaf-leaves；学科名词 physics/chemistry 无复数；职业名词 chemist 物理学家、physicist 化学家。
（四）拓展构词（九上新词汇变形）
名词→形容词：society→social、nature→natural、wood→wooden、care→careful/careless；
反身代词：myself、ourselves、themselves，搭配 enjoy oneself；
多义词转换：value v. 重视→valuable adj. 有价值；change v. 改变→changeable adj. 多变。
二、标准化四步解题技巧（考场直接套用）
第一步：判定词根词性，锁定变形方向
括号为动词：优先现在完成时、被动语态、to do/doing、名词 / 形容词； 括号为形容词：优先副词、比较级 / 最高级、抽象名词； 括号为名词：优先复数、形容词、抽象名词； 括号为代词：变形反身代词、物主代词。
第二步：抓取句中标志词，定时态 / 等级
时态信号：since/for→现在完成时；in + 过去年份、yesterday→一般过去时；be + 宾语 + by→被动语态；
等级信号：than→比较级；in/of all、one of→最高级；
搭配信号：介词 to 后 doing、want 后 to do、make 后动词原形。
第三步：分析句子成分，确定所需词性
主语、宾语、介词后→填名词；
修饰名词、be 动词后→填形容词；
修饰动词、形容词、整句话→填副词；
主语后作谓语→填动词（时态、语态变形）。
第四步：核查特殊拼写，规避高频陷阱
被动、完成时必须用过去分词，不可误用过去式；
-ed/-ing 形容词不可混用；friendly 仅为形容词，不能修饰动词；
抽象名词后缀易错：pronunciation、convenience 拼写易漏字母；
双写规则：辅元辅重读结尾双写（stop-stopped），open、visit 不双写。
