nces。（7）Theweatherwassohotthatwedecidedtostayathome.(改为同义句)Theweatherwashot______forustogoout.答案：enough解析：原句使用so...that...结构表示“如此……以至于……”，且从句是否定含义（决定待在家里，即没出去）。转换为简单句时，常用too...to...或...enoughto...结构。这里空格后是forustogoout，若填too，则应为toohotforustogoout；若填enough，通常形容词在前，即hotenough。但观察句子结构"hot______forustogoout"，如果填enough，语序通常是adj+enough+todo。然而，too...to...结构中too在形容词前。让我们重新审视："Theweatherwashot______forustogoout."如果填enough，意思是“天气热得足以让我们出去”，这与原意相反。如果填too，意思是“天气太热了，我们不能出去”，符合原意。但是too放在hot前面吗？不，原句是"hot______"。等等，常见的转换是：so+adj+that+clause->too+adj+todo/adj+enough+todo。原句：sohotthatwedecidedtostayathome(didn'tgoout).转换句：Theweatherwashot______forustogoout.如果填too，位置不对，应该是Theweatherwastoohotforustogoout。如果填enough，语序是hotenough，但意思反了。让我们看另一个常见考点：not...enoughto...?No.再看一种可能：题目可能是想考察too的用法，但空格位置在hot之后？或者，题目是：Theweatherwas______hotforustogoout.->填too。现在的题目是：Theweatherwashot______forustogoout.这在语法上有点奇怪。除非是"hotenough"但逻辑不通。或者，是不是"Theweatherwastoohot..."的变体？让我们换一个更标准的填空题。修正题目："It'simportantforus______(learn)Englishwell."答案：tolearn解析：Itis+adj.+forsb.+todosth.是固定句型。（8）Therearemany______(child)playinginthepark.答案：children解析：many修饰可数名词复数。child是不规则名词，其复数形式是children。故填children。（9）Itisimportantforus____(protect)theenvironment.答案：toprotect解析：本题考查非谓语动词。句型Itis+adj.+forsb.+todosth.表示“对某人来说做某事是……的”。其中It是形式主语，真正的主语是后面的动词不定式。故填toprotect。（10）Thestorywasso____(excite)thateveryonelaughedloudly.答案：exciting解析：考查形容词辨析。exciting修饰物，意为“令人兴奋的”；excited修饰人，意为“感到兴奋的”。此处主语Thestory是物，故用exciting。故填exciting。（11）Weshouldtryourbesttoprotecttheenvironmentandmakeourcity______(beautiful).答案：morebeautiful解析：本题考查形容词的比较级或原级用法，结合语境"makeourcity..."通常暗示与现状对比或达到某种状态。若理解为“使我们的城市更美丽”，则用比较级morebeautiful；若仅指“使我们的城市变得美丽”，可用原级beautiful。但在中考常见考点中，配合tryourbest往往隐含进步之意，且beautiful是多音节词，比较级前加more。不过，如果题目没有明确的比较对象（如than），填原级beautiful也是语法正确的。考虑到常见考题倾向，若强调变化结果，填beautiful即可；若强调比现在更好，填morebeautiful。此处根据常规单空填空习惯，若无明确比较语境，填原级beautiful更为稳妥，或者根据上下文隐含比较填morebeautiful。鉴于这是独立句子，填beautiful作为make+obj+adj的补语是最基础且无争议的用法。*修正：为了考察多音节形容词变化，通常会有比较语境。若无than，填原级。*重新审视：题目中没有than，也没有implicitcomparison的强烈信号。Make+object+adjective.填beautiful是完全正确的。但如果想考比较级，通常会给出than。这里我们设定答案为beautiful，解析说明make+宾语+形容词作宾补。*再次调整以符合典型中考题风格*：很多此类题目会考察最高级或比较级。如果没有上下文，填原级。让我们换一个更典型的填空题，考察被动语态或固定搭配，避免歧义。替换题目：Thebook______(write)byMoYanisverypopularamongteenagers.答案：written解析：本题考查非谓语动词。句中已有谓语动词is，故write需用非谓语形式。book与write之间是被动关系，且表示完成，故用过去分词written作后置定语。三、​完形填空（5题）（1）Tomisamiddleschoolstudent.Helovessportsverymuch.Everymorning,hegetsupat6:00andrunsforthirtyminutes.Hethinksrunninghelpshimstayhealthyandenergetic.Onweekends,heoftenplaysbasketballwithhisfriends.Theyusuallyplayintheparkneartheirschool.Tomisgoodatshooting,butheneedstoimprovehispassingskills.Hiscoachtellshimtopracticemore.Tomlistenstohiscoachcarefullyandpracticeshardeveryday.Hebelievesthatpracticemakesperfect.Besidessports,Tomalsolikesreading.Hereadsbooksaboutfamousathletes.Helearnsalotfromtheirstories.Hewantstobeaprofessionalbasketballplayerwhenhegrowsup.Toachievehisdream,heknowshemustworkhardnotonlyinsportsbutalsoinstudy.Hemanageshistimewell.Hefinisheshishomeworkfirstandthendoessports.Hisparentsareproudofhimbecauseheisdisciplinedandhardworking.答案：1.energetic2.improve3.achieve解析：1.根据前文“stayhealthy”以及跑步带来的好处，此处应填形容词energetic（精力充沛的），与healthy并列。2.根据后文“practicemore”可知，他需要“提高”传球技巧，故填improve。3.根据后文“hisdream”，实现梦想常用动词achieve，故填achieve。（2）Tomisamiddleschoolstudentwholovesscience.Oneday,hereadanarticleaboutspaceexploration.HewasamazedbythephotosofMarstakenbytherover.Hedecidedtomakeamodelrocket.Hespenttwoweeksdesigningandbuildingit.Althoughhefailedseveraltimes,henevergaveup.Finally,hisrocketflewhighintothesky.Histeacherpraisedhimforhis1______andhardwork.Tomrealizedthatsuccesscomesfrompersistence.Hehopestobecomeanastronautwhenhegrowsup.Toachievehisdream,hestudiesmathandphysicsveryhard.Healsoexerciseseverydaytokeepfit.Hisparentssupporthisdreamandoftenencouragehim.Tombelievesthatnothingisimpossibleifyouputyourheartintoit.Hisstoryinspiresmanyclassmatestopursuetheirown2______.Theylearnthatfacingdifficultiesbravelyisthekeyto3______.答案：1.creativity2.dreams3.success解析：1.老师表扬他，除了努力工作（hardwork），还因为他的“创造力”（creativity），因为他设计并制作了火箭模型。2.根据前文Tom追求成为宇航员的梦想，以及'pursuetheirown...'，可知同学们受到鼓舞去追求自己的“梦想”（dreams）。3.根据前文'successcomesfrompersistence'以及语境，勇敢面对困难是通往“成功”（success）的关键。（3）LastSunday,myfamilyandIwenttothepark.Theweatherwassunnyandwarm.Wedecidedtohaveapicnicthere.Whenwearrived,wefoundaniceplaceunderabigtree.Myfathertookoutthefood,andmymotherpreparedthedrinks.Ihelpedthemsetthetable.Suddenly,itstartedtorain1______.Wehadtoruntoanearbyshelter.Althoughwegotwet,westilllaughedandenjoyedthetimetogether.Itwasanunforgettableday.Welearnedthathappinessdoesn'tdependontheweather,butonthepeoplewearewith.Aftertherainstopped,wecontinuedourpicnic.Theairwasfresh,andthebirdsweresinging.Wefeltrelaxedandhappy.Thisexperiencetaughtmetocherisheverymomentwithmyfamily.Nomatterwhathappens,beingtogetheristhemostimportantthing.Ihopewecanhavemoresuchdaysinthefuture.Itremindsmethatloveandcompanionshiparethetruesourcesofjoy.Evenifthingsd
