_____________________________________________________________________等表意向、打算、計劃的名詞時，或者以_____________________表示時，一般用動詞不定式作表語說明主語的內容。method，problem，task，wish，aim，goal，purpose，suggestion，duty，hope，idea，intention，plan，way，stepwhat引導的名詞性從句有時，根據(jù)表達的需要，在作表語的不定式前，還可添加疑問代詞或疑問副詞，包括what,who,how,when,where等。例如：Theproblemwashowtobegin.Thebestwaytodobusinessistobuildtrustbetweenyouandyourclient.Forahumbleperson,oneofthehardestthingsmightbetocriticiseotherpeople.【P5activity2】Underlinethenounsorclausesusedasthesubjectineachsentence.Explainthemeaningsofthecompletesentences.tip2當主語包含定語從句且其先行詞為代詞_____或者主語被___________________或形容詞________修飾時，其后可接“系動詞+不定式”作句子的表語。allonly,first,one,least最高級tip3動詞不定式作表語可表“________________________________________”等。Inourcountry，peopleunder18are____________.(禁止)在我們國家，未滿18周歲的人禁止開車。Youmustbepatientandpersistentifyouare___________.(愿望)如果你想成功，你必須有耐心和恒心。Youare_________aface-to-facetalkwiththem.(勸告)

你必須得和他們進行一次面對面的談話。nottodrivetosucceed

同意、安排、命令、決定、勸告、意愿、禁止等tohave4.表示事態(tài)發(fā)展的結果、預期的結果、不幸的命運或預言。Thatexperiencewastochangehiswholelife.那次經歷會改變他的整個生活。Youmusttellmeaboutit，ifwearetoremainfriends.如果我們還想繼續(xù)做朋友的話，你就必須告訴我那件事。5.用于被動語態(tài)，相當于can/could，should，oughtto，must，具有情態(tài)意義。Youaretoberewarded.你應該受到獎勵。(should)It’snowheretobefound.哪兒也找不到它。(can’tbe)Thesebooksarenottobesold.這些書不應該被賣掉。(oughtnottobe)6.不定式作表語，可用主動形式表示被動意義。Yourclientistoblameforthelossofsomuchmoney.損失這么多錢應該怪你的客戶。7.動詞不定式(短語)作表語時，一般情況下不定式符號to不能省略，但當主句主語部分含有實義動詞do的某種形式時，可省略作表語的動詞不定式（短語）里的不定式符號to:

Whattheyattemptedtodowasnolongershowreality,butinsteadtoaskthequestion,“Whatisart?”Intheevening

theonlythinghedidwasreadthenewspaper.三、動詞不定式作表語和v-ing作表語的區(qū)別

1、當動詞所表達的是某一具體的行為，將來的行為或有待于實現(xiàn)的行為時，通常用動詞不定式作表語。

v-ing動名詞作表語則表示多次的、反復的、習慣性的行為與動作。2、動詞不定式和v-ing作表語時，要注意與句子的主語在形式上保持一致，即如果句子的主語為v-ing，則表語也應使用v-ing；若主語為動詞不定式,

則表語也應使用動詞不定式。e.g.Toseeistobelieve.=Seeingisbelieving.Whatheisaddictedtoisplayingvideogamesatnight.▲但這種區(qū)別并不是絕對的。例外的情況也不少，比如在job，problem等名詞后面就可用不定式或動名詞作表語，且意思區(qū)別很小。如：Theproblemisfindingthetimetogetthesethingsdone.問題是要找到完成這些事情的時間。Theproblemistofindasuitableplaceforthesculpture.問題是要找到一個合適的地方安放這個雕塑。
