3、anaged to escape from the fire.I find it hard to get along with him.（it 作形式賓語）（2）動(dòng)詞+疑問詞+to，特殊疑問句+不定式相當(dāng)于名詞，作賓語。I dont know what to do next/ how to do it next.不定式短語作賓語時(shí)，如果還帶有賓語補(bǔ)足語，往往把不定式短語放在賓語補(bǔ)足語之后，用it 作形式賓語。I find it necessary to learn a foreign language.3. 作賓語補(bǔ)足語（1）動(dòng)詞+賓語+不定式（to do ）。He warned me to

13、(early), Pahlsson had removed the diamond ring 61 (cook) a meal.【參考答案】to cook 【答案解析】考查動(dòng)詞不定式。一個(gè)句子不能出現(xiàn)雙重謂語，所以此處要用不定式作目的狀語。故填to cook?？枷蚨?不定式的時(shí)態(tài)和語態(tài)1. 不定式的時(shí)態(tài)（1）現(xiàn)在時(shí)：有時(shí)與謂語動(dòng)詞表示的動(dòng)作同時(shí)發(fā)生，有時(shí)發(fā)生在謂語動(dòng)詞的動(dòng)作之后。He seems to know this. （2）完成時(shí)：表示的動(dòng)作發(fā)生在謂語動(dòng)詞表示的動(dòng)作之前。Im sorry to have given you so much trouble.He seems to have

15、補(bǔ)足語的不定式必須省略to。如：My mother wouldnt let me go to the film. 我媽媽不會(huì)讓我去看電影的。I dont like milk, but mother made me drink it. 我不喜歡牛奶，可是母親強(qiáng)迫我喝。注意： 1. 當(dāng)使役動(dòng)詞用于被動(dòng)語態(tài)時(shí)，要補(bǔ)上在主動(dòng)語態(tài)中省略的to(主要是指make，let和have很少用于被動(dòng)語態(tài))。2. force, oblige等雖然也表示2. force, oblige使，但它們后用作賓語補(bǔ)足語的不定式必須帶to。如：He forced me to go with them. 他迫使我同他們一起去。T
16、he police obliged him to leave. 警方強(qiáng)迫他離開。二、感官動(dòng)詞后省略to的情況在感覺動(dòng)詞后用作賓語補(bǔ)足語的不定式必須省略to。如：I watched her get into the car. 我看著她上了車。I saw the woman enter a bank. 我看見這個(gè)女人進(jìn)了一家銀行。We often hear her sing this song. 我們經(jīng)常聽到她唱這首歌。 Did you notice her leave the house? 她離開屋子你注意到了嗎?注意：1. 這里所說的感覺動(dòng)詞主要包括see, hear, observe, no
17、tice, feel, watch等。但是它們用于被動(dòng)語態(tài)時(shí)，其后的不定式必須帶to。但是，用于以上句型的動(dòng)詞notice 和watch和通常不用于被動(dòng)語態(tài)。2. 類似地，動(dòng)詞look at和listen to后用作賓語補(bǔ)足語的不定式也不帶to。3. 若動(dòng)詞feel后用作賓語補(bǔ)足語的不定式為 to be，則要帶 to(其他情況不帶 to)。4. 若不定式為完成式，通常應(yīng)帶 to。三、動(dòng)詞help后省略to的情況在動(dòng)詞help后用作賓語或賓語補(bǔ)足語的不定式可以不帶to。如：Can I help (to) carry this heavy box? 我可以幫忙扛這個(gè)重箱子嗎？Mother help
18、ed me (to) do my homework. 媽媽幫助我做作業(yè)。注意：1. 當(dāng) help 之后接一個(gè)較長的名詞詞組作賓語或當(dāng)其中的不定式所表示的動(dòng)作主語不直接參加時(shí)，不定式通常帶to。如：Help the little boys at the back of the hall to carry the chairs out. 請(qǐng)幫大廳后面那些小男孩把椅子搬出去。These tablets will help you to sleep. 這些藥片將對(duì)你的睡眠有幫助。2. 在當(dāng)help用于被動(dòng)語態(tài)時(shí)，不定式前的to不能省略。如：The boy was helped by a woman t

20、不定式通常不帶 to；若其前沒有出現(xiàn)動(dòng)詞 do，則其后的不定式通常帶 to。如：I had no choice but to wait. 除了等，我沒有別的選擇。He wanted nothing but to stay there. 他只想留在那兒。It had no effect except to make him angry. It had no effect except to make him angry. 除惹他生氣外，沒產(chǎn)生任何效果。She can do everything except cook. 除了做飯之外她什么都會(huì)。六、主語帶do表語省略to的情況當(dāng)主語部分有動(dòng)詞do
21、的某種形式時(shí)，用作表語的不定式可以省略to。如：All you do now is (to) complete the form. 你現(xiàn)在要做的只是把這張表填好。The only thing to do now is (to) go on. 前進(jìn)是現(xiàn)在唯一的出路。What Ill do is 我要做的就是告訴她真相。七、并列不定式省略to的情況當(dāng)兩個(gè)或多個(gè)作用相同的不定式并列時(shí)，通常只需在第一個(gè)不定式前用to，其余不定式前的to可以省略。如：He told me to stay there and wait for him. 他叫我在那兒等他。Im really puzzled what to
22、 think or say. 我真不知該怎么想怎么說。It is easier to persuade people than (to) force them. 說服人容易，強(qiáng)迫人難。但是，如果兩者有對(duì)比關(guān)系，則后面不定式前的to不可省略。如：To try and fail is better than not to try at all. 嘗試而失敗總比不嘗試好。八、省略不定式是否保留to在一定的上下文中，為了避免重復(fù)，有時(shí)不定式可以省略，但通常保留不定式符號(hào)to。如：I shall go if I want to. 如果我想去就去。 Dont be late. Ill try not to
23、. 不要來晚了。我盡量不來晚。Dont go till I tell you to. 等我叫你走你再走。注意：1. 若被省略的不定式為to be短語，則通常應(yīng)保留to be。如：He is not the man he used to be. 他已不是原來的那個(gè)樣子了。2. 有時(shí)省略不定式時(shí)，同時(shí)也可省略to。如：She may go if she likes (to). 她想去就可以去。They knew her very well.

35、一 基礎(chǔ)過關(guān)單項(xiàng)填空1.A 【解析】考查非謂語動(dòng)詞。根據(jù)句意在2016年的第三季度北歐的旅游支出穩(wěn)步上升，比上一季度增長0.1%。 和句子結(jié)構(gòu)可知， _in Northern Europe是句子的主語，所以動(dòng)詞spend該用ing形式（即動(dòng)名詞），而Tourist是動(dòng)名詞的邏輯主語，所以A項(xiàng)（Tourist spending游客花銷/旅游支出）的結(jié)構(gòu)正確且符合語境之意。故選A。2.C 【解析】考查非謂語動(dòng)詞。it是形式主語，to do（動(dòng)詞不定式）作真正的主語。構(gòu)成It is +adj. to do 結(jié)構(gòu)。3.A 【解析】考查不定式短語作主語的用法。句意:數(shù)據(jù)定期更新很重要。題干屬于It+be
36、+adj.+for sb./sth.+不定式結(jié)構(gòu)，該結(jié)構(gòu)中,It為形式主語，不定式為真正的主語。update與the figures為動(dòng)賓關(guān)系，所以不定式用被動(dòng)形式，而且此處陳述的是一般情況，不涉及謂語動(dòng)作與非謂語動(dòng)作的先后次序，故用不定式的一般被動(dòng)式作主語，所以A項(xiàng)切題。4.C 【解析】考查非謂語動(dòng)詞。句意：看到孩子們?cè)谀莾和娣浅Ｓ腥?。由語境可知，孩子們正在那邊玩。該題考查watch sb. doing sth.結(jié)構(gòu)，意為看到某人正在做某事，故第二個(gè)空填playing。doing做主語，表示經(jīng)常性的動(dòng)作。to do做主語，表示某一次的行為。由語境可知，該處并不是經(jīng)常性的動(dòng)作。故要用to do
37、作主語。C選項(xiàng)切題。7.C 【解析】考查不定式。句意：獨(dú)自住在村里的奶奶，每晚只是喜歡舒適地坐在電視機(jī)前，快樂地觀看中國傳統(tǒng)戲劇節(jié)目。此處源于詞組be happy to do sh.樂意做某事，該空處為形容詞詞組作狀語，修飾主語的狀態(tài)。故選C。8.A 【解析】該句是感嘆句，解題時(shí)應(yīng)將其還原為陳述句：the pictures is pleasant to 該結(jié)構(gòu)中不定式作狀語修飾作表語的形容詞pleasant，且look at與句子主語是邏輯上的動(dòng)賓關(guān)系，sb/sth is adj to do sth是固定句式，用不定時(shí)的主動(dòng)表被動(dòng)，選A項(xiàng)。9.C 【解析】考查非謂語。句意：Tom非常自豪被選為
38、我們校足球隊(duì)的隊(duì)長。根據(jù)句意可知要運(yùn)用被動(dòng)語態(tài)，用現(xiàn)在完成時(shí)的被動(dòng)語態(tài)表示此事已經(jīng)發(fā)生，且有一定影響。故選C。10.C 【解析】考查非謂語動(dòng)詞。句意：公司里的許多員工說，對(duì)付Eric是不可能的。他確實(shí)很難對(duì)付。hard, difficult, easy, impossible等形容詞作表語時(shí)，其后的不定式如果與主語之間是邏輯上的動(dòng)賓關(guān)系，通常用不定式的主動(dòng)形式，故選to deal with。題組二 能力提升【語篇解讀】本文介紹了筷子的材質(zhì)與中國使用筷子的悠久歷史及文化內(nèi)涵。1.and 【解析】考查并列連詞。分析句子結(jié)構(gòu)及語境可知，Vietnam與空前的China， Japan， Korea之間
39、是并列關(guān)系，故填并列連詞and。4.using 【解析】考查非謂語動(dòng)詞。use與其邏輯主語People之間是主謂關(guān)系，故此處用現(xiàn)在分詞作狀語。5.as/when 【解析】考查狀語從句。隨著人口的增長或當(dāng)人口增長時(shí)，人們開始把食物切成小片。根據(jù)句意和句子結(jié)構(gòu)可知，空處引導(dǎo)狀語從句，表示隨著或當(dāng)時(shí)，故填as或when。6.gradually 【解析】考查副詞。應(yīng)用副詞修飾動(dòng)詞，故用 gradually。7.who 【解析】考查定語從句。分析句子結(jié)構(gòu)可知，空處在此引導(dǎo)非限制性定語從句，先行詞為Confucius，且關(guān)系詞在從句中作主語，故填who。8.development【解析】考查名詞。根據(jù)空前
40、的the及空后的of可知，此處應(yīng)填名詞development。9.were 【解析】考查時(shí)態(tài)和主謂一致。根據(jù)句中的believed可知，此處描述的是過去的情況，應(yīng)用一般過去時(shí)；從句主語為knives，謂語動(dòng)詞應(yīng)用復(fù)數(shù)。故填were。10.with 【解析】考查介詞。此處指大部分人用手吃飯，故填with。題組三 體驗(yàn)真題1.D 【解析】考查不定式作目的狀語。句意：為了更方便地聯(lián)系到我們，你最好隨身帶著這張卡片。根據(jù)句意可知，這里是目的狀語，表目的用動(dòng)詞不定式，故選D。2.to create【解析】考查不定式作目的狀語。技術(shù)嫻熟的工人會(huì)把各種各樣的硬質(zhì)木材和金屬結(jié)合起來，以創(chuàng)造出特殊風(fēng)格的筷子。這里用不定式表目的，故填to create。4.C 【解析】it是形式主語，真正的主語是后面的動(dòng)詞不定式。句意：像這樣的一個(gè)公司雇用一名保安是慣例。故答案選C。5.A 【解析】由結(jié)構(gòu)判斷此處是非謂語短語位于句首表示目的，現(xiàn)在分詞不做目的狀語，排除CD選項(xiàng)。To be doing強(qiáng)調(diào)正在進(jìn)行，不能做目的狀語，故答案選A。句意：-我希望選修計(jì)算機(jī)課程。-好主意。要想多了解計(jì)算機(jī)情況的話，去這個(gè)網(wǎng)站看看。 14
