九年級英語單元知識點(diǎn)系統(tǒng)總結(jié)（核心考點(diǎn)+實(shí)用技巧）一、關(guān)鍵詞匯與短語本單元圍繞“學(xué)習(xí)策略”展開，需重點(diǎn)掌握詞匯的詞義、詞性轉(zhuǎn)換及固定搭配：pronounce(v.)發(fā)音→pronunciation(n.)發(fā)音；讀音（搭配：*correctone’spronunciation*糾正發(fā)音）increase(v.)增加；增長→短語：*increase...by...*（增加了…）；*increase...to...*（增加到…）speed(n.&v.)速度；加速→搭配：*atahighspeed*高速；*speedup*加速review(v.&n.)復(fù)習(xí)；回顧→聯(lián)想：*preview(v.)*預(yù)習(xí)二、語法重點(diǎn)：“by+動名詞”表方式&現(xiàn)在完成時1.“by+doing”結(jié)構(gòu)（表方式/手段）用于說明“做某事的途徑”，常回答*how*引導(dǎo)的問句。例句：*—HowdoyoulearnEnglish?—IlearnEnglishbyreadingaloudeverymorning.*拓展短語：*byaccident*（偶然）；*bymistake*（錯誤地）2.現(xiàn)在完成時（have/has+過去分詞）兩種核心用法：①過去動作對現(xiàn)在的影響（標(biāo)志詞：*already,yet,just,ever,never*）：*Ihavealreadyfinishedmyhomework.（現(xiàn)在無需再做）*②過去持續(xù)到現(xiàn)在的動作（標(biāo)志詞：*for+時間段,since+時間點(diǎn)/從句*）：*Shehaslivedheresince2010./HehasstudiedEnglishforthreeyears.*三、重點(diǎn)句型解析1.“It’s+adj.+(for/ofsb.)+todosth.”用*for*時，adj.描述“事情”的性質(zhì)（如*difficult,easy,important*）：*It’simportantforustopracticespeakingeveryday.*用*of*時，adj.描述“人的品質(zhì)”（如*kind,nice,clever*）：*It’skindofyoutohelpmewithmyEnglish.*2.“The+比較級,the+比較級”（越…，越…）例句：*Theharderyoustudy,thebettergradesyou’llget.*拓展：*Themoreyouread,thefasteryou’llimproveyourreadingskills.*四、寫作指導(dǎo)：“學(xué)習(xí)方法建議信”結(jié)構(gòu)模板：1.開頭：點(diǎn)明主題（如*“I’mwritingtosharesomeeffectivewaystolearnEnglish.”*）2.中間：分點(diǎn)講方法（用*bydoing*結(jié)構(gòu)）：*Firstly,youcanlearnnewwordsbymakingwordcards.Besides,improvinglisteningskillsbywatchingEnglishmoviesisalsohelpful.*3.結(jié)尾：鼓勵總結(jié)（如*“Ihopethesemethodswillworkforyouandmakeyourlearningeasier.”*）---Unit2Ithinkthatmooncakesaredelicious!（節(jié)日文化主題）一、文化類詞匯與搭配mooncake(n.)月餅；lantern(n.)燈籠；stranger(n.)陌生人→詞根：*strange(adj.)*奇怪的；陌生的admire(v.)欣賞；仰慕→搭配：*admiresb.forsth.*（因某事欽佩某人）；*admirethemoon*賞月relative(n.)親屬；親戚→短語：*closerelatives*近親；*distantrelatives*遠(yuǎn)親二、語法重點(diǎn)：賓語從句&感嘆句1.賓語從句（陳述語序+引導(dǎo)詞）that引導(dǎo)（表陳述，*that*可省略）：*Ithink(that)mooncakesaredelicious.*語序要求：連接詞后用陳述語序（如：*Iaskwhatheisdoing.*而非*whatishedoing*）2.感嘆句（What/How引導(dǎo)）What引導(dǎo)：*What+(a/an)+形容詞+名詞+主語+謂語!*（名詞可數(shù)時用*a/an*）*Whatabeautifulcity(itis)!/Whatdeliciousfood(itis)!*How引導(dǎo)：*How+形容詞/副詞+主語+謂語!**Howbeautifulthecityis!/Howfastheruns!*三、寫作指導(dǎo)：“介紹傳統(tǒng)節(jié)日”內(nèi)容框架：1.開頭：點(diǎn)明節(jié)日名稱與時間（如*“TheMid-AutumnFestivalfallsonthe15thdayofthe8thlunarmonth.”*）2.中間：描述習(xí)俗+文化意義（用賓語從句豐富內(nèi)容）：*Peoplebelievethatadmiringthefullmoononthisdaybringsgoodluck.Familiesalsogettogethertosharemooncakesandstories.*3.結(jié)尾：總結(jié)節(jié)日價值（如*“It’satimetoshowloveforfamilyandpassontraditionalculture.”*）---跨單元核心語法：被動語態(tài)（九年級重點(diǎn)）一、結(jié)構(gòu)：be+過去分詞（時態(tài)通過*be*的形式變化）一般現(xiàn)在時：*am/is/are+done**Englishisspokenallovertheworld.*一般過去時：*was/were+done**ThebookwaswrittenbyLuXun.*含情態(tài)動詞：*情態(tài)動詞+be+done**Theworkmustbefinishedtoday.*二、用法場景強(qiáng)調(diào)“動作的承受者”（而非執(zhí)行者）：*Thenewlibrarywasbuiltlastyear.*（重點(diǎn)在“圖書館被建”）執(zhí)行者不明/無需說明：*Thewindowwasbrokenyesterday.*（無需說“誰打破的”）三、主動變被動的步驟1.原句賓語變被動句主語；2.謂語變“*be+過去分詞*”（時態(tài)與原句一致）；3.原句主語若需保留，用“*by+主語（賓格）*”置于句末。例句：*Peoplegrowriceinthesouth.→Riceisgrown(bypeople)inthesouth.*---通用學(xué)習(xí)技巧（詞匯+寫作）一、詞匯記憶策略1.構(gòu)詞法：派生：*happy→unhappy*（否定前綴*un-*）；*use→useful*（后綴*-ful*表“充滿…的”）合成：*class+room→classroom*；*black+board→blackboard*2.語境記憶：將單詞放入句子/短文（如*“WeeatmooncakesduringtheMid-AutumnFestival.”*）3.聯(lián)想記憶：同義詞（*big-large*）、反義詞（*happy-sad*）、同音詞（*right-write*）二、寫作高分技巧1.結(jié)構(gòu)清晰：開頭點(diǎn)題，中間分2-3個論點(diǎn)（用*firstly,besides,finally*連接），結(jié)尾升華。2.語法
