第09講 疑問詞+to do 結(jié)構(gòu)-【暑假自學(xué)課】2023年新九年級(jí)英語暑假課（仁愛版）（原卷版）

第頁第09講疑問詞+todo結(jié)構(gòu)＂疑問詞＋不定式＂結(jié)構(gòu)的用法：一、構(gòu)成由疑問代詞who,whom,what,which;疑問副詞when,how,where等+不定式構(gòu)成。二、功能1.作主語作主語時(shí)，謂語動(dòng)詞常用單數(shù)形式。?Howtodoitisaquestion.該怎樣做倒是一個(gè)問題。2.作賓語①作動(dòng)詞的賓語?IaskedhimhowtolearnEnglish.我問他如何學(xué)習(xí)英語。②作介詞的賓語?Wemustfirstsolvetheproblemofwhomtoserve.我們必須首先解決為誰服務(wù)的問題。3.作表語?Thequestioniswheretoputit.問題是該把它放在哪兒才好。三、替換＂疑問詞＋不定式＂結(jié)構(gòu)相當(dāng)于一個(gè)名詞性從句，常常可用同等成分的從句代替。改寫時(shí)只需在疑問詞后加一適當(dāng)主語，并將不定式改成適當(dāng)形式的謂語。上述例句可以分別改寫成：學(xué)科@網(wǎng)?Howweshoulddoitisaquestion.?Ireallydon’tknowwhatIshouldwriteabout.?IaskedhimhowweshouldlearnEnglish.?Wemustfirstsolvetheproblemofwhomweshouldserve.?Thequestioniswhereweshouldputit.二、五個(gè)易錯(cuò)點(diǎn)易錯(cuò)一：是否用于疑問詞why之后按英語習(xí)慣，有一個(gè)疑問詞不能用于“疑問詞+不定式”結(jié)構(gòu)，就是why。我不明白為什么馬上就走。誤：Idon'tknowwhytoleaveatonce.正：Idon'tknowwhywemustleaveatonce.不過，why后面可以跟不帶to的動(dòng)詞不定式(即動(dòng)詞原形)，用以表示某動(dòng)作是不必要的或無意義的。Whypaymoreatothershops?Wehavethebestvalue.為什么花更多的錢到其他商店去買呢?我們這里最物美價(jià)廉。另外，why后面不帶to的動(dòng)詞不定式有時(shí)也可能是否定的，該結(jié)構(gòu)主要用來提出建議。You'relookingtired.Whynottakeaholiday?你一臉倦容，怎么不休假呢?易錯(cuò)二：與動(dòng)詞think連用有何特別之處“疑問詞+不定式”結(jié)構(gòu)，通常不用于動(dòng)詞think的現(xiàn)在式和過去式之后，但可以用于think的其他形式之后（如進(jìn)行式）。I'mthinkingwhattodonext.我在想接下來要做什么。另外，“疑問詞+不定式”結(jié)構(gòu)也通常用于還有助動(dòng)詞的think之后。Shecouldn'tthinkwhattosay.她想不出該說什么。Shecouldn'tthinkwhattogivethechildrenforChristmas.她想不出圣誕節(jié)該送孩子們什么禮物。易錯(cuò)三：與動(dòng)詞know連用要注意什么當(dāng)要表示知道如何做某事，know之后不能直接跟動(dòng)詞不定式作賓語，此時(shí)可改用knowhowto結(jié)構(gòu)。我會(huì)做西班牙式的攤雞蛋。誤：IknowtomakeSpanishomelets.正：IknowhowtomakeSpanishomelets.易錯(cuò)四：與某些只接動(dòng)名詞作賓語的動(dòng)詞連用有些動(dòng)詞可以接“疑問詞+不定式”作賓語，但通常不直接跟不定式作賓語。這類動(dòng)詞主要有consider(考慮),discover(發(fā)現(xiàn)),discuss(討論),explain(說明),find(out)(查到),know(知道),observe(觀察),suggest(提議),wonder(懷疑),understand(了解)等。Haveyouconsideredhowtogetthere?你是否考慮過如何到那兒去?Ourteacherexplainedhowtousethemachine.老師向我們說明如何使用這臺(tái)機(jī)器。Wediscussedwhattodoandwhereweshouldgo.我們討論了該怎么辦及到哪里去。易錯(cuò)五：whichtodo的兩種用法要注意“which+不定式”結(jié)構(gòu)，其中的which有時(shí)是疑問詞。Ican'tdecidewhichtochoose.我不能決定選哪個(gè)好。Didyouaskherwhichtobuy?你問沒問她該買哪一個(gè)?有時(shí)可能是關(guān)系代詞，相當(dāng)于一個(gè)省略的定語從句，此時(shí)主要用于介詞后作賓語。Shemusthavetimeinwhichtogrowcalm.她必須有冷靜下來的時(shí)間。Allowmeoneminuteinwhichtochangemycostumes.給我一點(diǎn)時(shí)間來卸裝。這兩句中的whichto…也可改為定語從句：Shemusthavetimeinwhichshecangrowcalm.AllowmeoneminuteinwhichIcanchangemycostumes.一、單項(xiàng)選擇11．Idon’tknow________withtherubbish.Canyoutellme?A．howdoit B．howtodo C．whatdoit D．whattodo2．Idon’tknow________next.A．whattodo B．whatshouldIdoC．howdo D．howshouldIdo3．—Ihaven’tdecided________.—WhataboutDongjintuoPark?It’sreallyagoodplacetorelax.A．whenIwillhaveatrip B．wherewillIspendmyweekendC．wheretospendmyweekend D．howIshouldrelaxmyself4．________isundecidedyet.A．Togowhichway B．WhichwaytogoC．Goingwhichway D．Whichtogoway5．—Idon’tknow________forthebirthdayparty.—Youlooksogoodnow.IthinkthepinkT-shirt________thegreyjeansverywell.A．whattowear;matches B．howtowear;matchesC．whattowear;fits D．howtowear;fits6．—Couldyoutellmehow________cakes?—Sorry,Idon’tknow.A．make B．making C．tomake7．Excuseme,wouldyoupleasetellme________buyacamera?A．whatto B．whereto C．whatIcan D．wherecanI8．—I’mthinkingabouthow________areportaboutALifelongJourney（《人世間》）.—Whynotreadsomereviewsfirst?A．towrite B．writing C．writes D．wrote9．Excuseme,couldyoutellme________?A．whattodo B．whatshouldIdo C．howtodo10．—ManyforeignersthinkeveryoneinChinaknows________TaiChi.—Thisisasillythought.ButitistruethatTaiChiispopularwithChinese.A．wheretodo B．howtodo C．whentodo11．—Excuseme,couldyoutellme_________mycar?—Sure.Thereisanewparkinglotbehindthebank.Youcanparkitthere.A．wheretopark B．whentopark C．howtopark12．—Couldyoutellme________thewelcomepartyforMr.Smith?—NextSaturday.A．whotothrow B．whentothrow C．wheretothrow13．TherearemillionsofnewinformationontheInterneteveryday.Thethingthatmattersis________tochooseusefulinformation.A．what B．how C．when14．I’vealreadytoldhimbutheisstillnotclear________todonext.A．whether B．what C．how15．—Idon’tknow________torememberthenewEnglishwords.—Don’tworry!Trythinkingabouttheirpronunciations.A．what B．how C．where D．when16．—Excuseme.Doyouknow________?—Sorry,Idon’tknow,either.A．thatthereisabanknearbyB．whenwilltheconcertbeginC．howtocheckoutabook17．—Frank,I’mintrouble.Ireallydon’tknow________next.—Don’tworry.Letmehelpyou.A．whattodo B．howtodo C．whentogo D．whytogo18．Couldyougivemesomeadviceon________Englishwell?A．whattolearn B．howtolearn C．howcanI19．Noonecanchangewhat’salreadyhappened.It’simportantthatweneedtoknow________.A．howshouldweusetheexperiencetolearn B．whotousetheexperiencetolearnC．whethercanweusetheexperiencetolearn D．howtousetheexperiencetolearn20．—Taylor,Ireallydon’tknowwhyIcan’timprovemyEnglish.Ihavetriedmybest.Couldyoupleasetellme________todealwiththiskindofproblem?—Takeiteasy!Makingprogressbitbybitisenough.Bepatientandconfident.A．how B．what C．why21．We’llhaveameetingthisafternoontodiscusswhat________next.A．do B．todo C．doing22．—Couldyoutellme________next?
