（她似乎因为某事而心烦。）2.Itseemsthatthepartywillbecanceled.

（这个派对好像要被取消了。）02.not...atall【释义】根本不；一点也不（加强否定语气）📌结构：否定句式(don't/doesn't/can't...)+atall（置于句末或句中）1.Idon'tmindyourdecisionatall.

（我一点也不介意你的决定。）2.Sheisn'tinterestedinthisbookatall.

（她对这本书根本不感兴趣。）03.rather(than)【释义】相反；而是；宁愿（表取舍或偏好）📌结构：AratherthanB/woulddoAratherthandoB1.Itisaflowerratherthanagrass.

（这是一朵花，而不是一棵草。）2.Iwouldwalkratherthantakeataxi.

（我宁愿走路也不愿坐出租车。）LanguagePoints01.workwith【核心释义】从事；研究；与……共事📌结构：后接名词/代词作宾语，强调合作对象或研究领域。常用于描述职业活动或协作关系。Sheworkswithateamofscientiststostudymarinebiology.

(她与一个科学家团队共事，研究海洋生物学。)02.thewaytodosth.【核心释义】做某事的方式/途径/方法📌结构：动词不定式todosth.作后置定语，修饰名词theway。等同于"thewayofdoingsth."，是写作中常用的高分句型。Confidenceisthebestwaytoovercomeyourfearofspeaking.

(自信是克服你说话恐惧的最好方法。)03.findsolutionsto...【核心释义】找到……的解决办法/方案📌搭配：Solution是可数名词，必须与介词to搭配（不能用of），后接具体的问题或难题，是考试和写作的高频考点。Wemustfindpracticalsolutionstotheglobalenergycrisis.

(我们必须找到解决全球能源危机的切实可行的方案。)Theinventionoftheplanehasmadeourtravelsaroundtheworldmucheasierandfaster.Journeysthatoncetookdays,weeks,orevenmonths,cannowbemadeinonlyafewhours.Asaresult,communicationamongpeopleindifferentcountriesisnowmucheasier,andtheworldhasbecomeamuchsmallerplace.Readthetextandcompletethechart.3a阅读分解：Para3💡MainIdeaTheplane'sinventionrevolutionizedglobaltravelandconnectivity.Ittransformedtheworldintoamoreaccessible"globalvillage",makinglong-distancetravelandinternationalcommunicationfastandconvenient.✍️ClassTask:Describeonewaytheplanehaschangedyourlifeortheworldusingthekeyphrasesabove.LanguagePoints01.makesth.+adj.结构解析：make作使役动词，后接“宾语+形容词”构成复合宾语，强调使某物达到某种状态或结果。📝Example:Thesoftmusicmadeusfeelrelaxedafteralongday.（轻柔的音乐让我们在漫长的一天后感到放松。）02.asaresult用法：连接性短语，用于引出上文动作或情况所产生的直接结果，常置于句首并用逗号隔开。📝Example:Hestudiedhardfortheexam.Asaresult,hegotthefirstplace.（他为考试努力学习，结果得了第一名。）03.much+比较级核心考点：much作为程度副词，修饰形容词或副词的比较级，强调程度上的“……得多”，不可用very替换。📝Example:Thismovieismuchmoreexcitingthantheonewesawlastweek.（这部电影比我们上周看的那部精彩得多。）GrammarFocus✨核心公式：一般过去时被动语态=was/were+过去分词(V-ed)（如:invented,made,created）01肯定句Affirmative结构：Sth.+was/were+inventedby...PaperwasinventedbyCaiLuninancientChina.译：纸是由蔡伦在古代中国发明的。02疑问句Interrogative结构：Was/Were+sth.+inventedby...?Weremobilephonesinventedinthe1970s?译：手机是在20世纪70年代被发明的吗？03否定句Negative结构：Sth.+wasn't/weren't+inventedby...Thelightbulbwasn'tinventedbyEinstein.译：灯泡并不是由爱因斯坦发明的。💡语法点睛：为何发明类话题偏爱被动语态？在讨论发明创造时，我们通常更关注“发明物本身”（动作的承受者）而非“发明者”（动作的执行者）。使用被动语态能自然地将句子焦点转移到物品上，符合英语表达的逻辑重心，同时也能避免在不知道或无需强调发明者时的表达尴尬。Completethetable.3a①Theplane.②TheWrightbrothers.③Toflylikebirds.④Howtogetthegliderintotheair;howtocontrolitonceitwasflying.⑤TheWrightbrotherswatchedhowbirdsflewandaddedanenginetotheglider.⑥InDecember1903.⑦Itmadetravelsaroundtheworldmucheasierandfaster.Itmadecommunicationamongpeopleindifferentcountriesmucheasierandturnedtheworldintoamuchsmallerplace.Chooseagreatinventionyouareinterestedin.Dosomeresearchandmakenotesaboutit.3b●-____________wasinventedby________________________in________________________.●-Itwasinventedbecause________________________________________________________.●-Itwasmadeof/from________________________________________________________.●-Theinventorhaddifficultiesin________________________________________________.●-Theinventionwasresponsiblefor/ledto______________________________________.GroupDiscussion3bGroupFormation:Formteamsof4students.Collaboratecloselytoshareideas.TimeLimit:Youhave5minutesforthediscussion.Stayfocused!01.TheGame-ChangerWhatinventiondoyouthinkisthemostimportantinhistory?Explainyourreasonsanddiscusshowithasfundamentallychangedthewaypeopleliveandwork.02.YourDreamCreationIfyoucouldinventonethingtosolveaproblemintheworld,whatwoulditbe?Describeitsuniquefunctions,whoitwouldhelp,andwhyit’sneededtoday.03.TheInventor’sDNAWhatpersonalqualitiesmakeagreatinventor?Listatleastthreekeytraits(e.g.,curiosity,resilience)anddiscusswhytheyarecrucialforinnovation.Writeabouttheinventionyouhavechosenusingtheinformationfrom3b.3c
