動(dòng)詞不定式的基本形式為“t+動(dòng)詞原形”(t有時(shí)也可省略), 其否定形式為“nt t+動(dòng)詞原形”。其基本用法如下:1.作主語(yǔ):可用it作形式主語(yǔ),將真正的主語(yǔ)置后。常用句型:It’s+ adj.(+fr/f sb.)+ t d sth.T master a cmputer skill is difficult. =It is difficult t master a cmputer skill. 掌握一項(xiàng)計(jì)算機(jī)技能是很困難的。In China, it is interesting t see peple eating with chpsticks. 在中國(guó),看到人們用筷子吃飯是蠻有趣的事情。(2021.69)
2.作表語(yǔ):常置于系動(dòng)詞之后。Yuan Lngping’s wish is t make peple never feel hungry. 袁隆平的愿望是使人們不再餓肚子。3.作定語(yǔ):置于被修飾的名詞之后,作后置定語(yǔ)。I have many questins in learning English, but I dn’t have a partner t discuss with. 我在英語(yǔ)學(xué)習(xí)方面有很多問(wèn)題,但我沒(méi)有搭檔可以討論。
4.作賓語(yǔ):(1)一般情況下,不定式作部分動(dòng)詞的賓語(yǔ)。經(jīng)常接不定式作賓語(yǔ)(動(dòng)詞+t d sth.)的動(dòng)詞有l(wèi)ike, want, hpe, agree, wish, decide, try, expect, refuse, affrd, plan, prmise, frget等。(2)“疑問(wèn)詞+不定式”作賓語(yǔ),常用疑問(wèn)詞有what, when, where, hw, which等,可轉(zhuǎn)化為賓語(yǔ)從句。Nbdy taught me hw t use a mind map t review.=Nbdy taught me hw I can use a mind gap t review. 沒(méi)人教過(guò)我怎么用思維導(dǎo)圖來(lái)復(fù)習(xí)。
(3)當(dāng)不定式作賓語(yǔ)時(shí),還可用it作形式賓語(yǔ),真正的賓語(yǔ)是不定式。常跟it作形式賓語(yǔ)的動(dòng)詞有find, think, make等。Students ften find it hard t tell the difference between the tw wrds.學(xué)生們經(jīng)常發(fā)現(xiàn)很難區(qū)分這兩個(gè)詞的區(qū)別。(4)不定式也可作某些形容詞的賓語(yǔ)。常見的這類形容詞有able, sure, glad, srry, afraid, pleased, ready等。Many yung Chinese are afraid t put n weight.許多中國(guó)年輕人害怕長(zhǎng)胖。
5.作賓語(yǔ)補(bǔ)足語(yǔ):Many pets advise us t value ur time and study hard. 許多詩(shī)人建議我們珍惜時(shí)間,努力學(xué)習(xí)。常接“賓語(yǔ)+賓補(bǔ)”(即“動(dòng)詞+sb.+ t d sth.”結(jié)構(gòu))的動(dòng)詞有tell, ask, warn, want, invite, allw, advise, help等。
注意:在一些使役動(dòng)詞和感官動(dòng)詞后,要把不定式結(jié)構(gòu)中的t省略。常見的有:五看:watch, see, ntice, lk at三使:let, have, make二聽:listen t, hear一感覺(jué):feel
I saw my mther enter the kitchen just nw. 剛才我看到媽媽進(jìn)廚房了。但在被動(dòng)語(yǔ)態(tài)的句子中,t通常要保留。Tm was seen t g t the library with his friend yesterday.
感官動(dòng)詞后跟動(dòng)詞原形和動(dòng)詞-ing的區(qū)別以see為例:see sb. ding sth. 看見某人正在做某事(看見動(dòng)作正在進(jìn)行)see sb. d sth. 看見某人做某事(看見全部過(guò)程)①I saw a mnkey crss the street. 我看見一只猴子穿越馬路。(表示看到“穿越馬路”這一全過(guò)程)②I saw a mnkey crssing the street. 我看見一只猴子正在穿越馬路。(表示看到“正在穿越馬路”這一正在進(jìn)行的動(dòng)作)
6.作狀語(yǔ):用來(lái)表示行為目的、結(jié)果、原因等,置于動(dòng)詞之后。I went ut f my way t wrk ut the math prblem. 我盡全力解出這道數(shù)學(xué)題。(表目的)Last night, we arrived hme very late, nly t find the dr lcked. 昨天晚上,我們到家非常晚,結(jié)果發(fā)現(xiàn)門被鎖了。(表結(jié)果)Mike was s sad t knw that he failed the English exam again. 邁克得知他又一次沒(méi)通過(guò)英語(yǔ)考試很傷心。(表原因)

動(dòng)名詞由“動(dòng)詞原形+-ing”構(gòu)成, 兼有動(dòng)詞和名詞的性質(zhì)。動(dòng)詞的性質(zhì)是可以接賓語(yǔ)和狀語(yǔ),組成動(dòng)名詞短語(yǔ);名詞的性質(zhì)是在句子中可充當(dāng)主語(yǔ)、表語(yǔ)、賓語(yǔ)等。His hbby is cllecting stamps.= Cllecting stamps is his hbby. 他的愛好是集郵。
注意:當(dāng)動(dòng)名詞結(jié)構(gòu)作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞用單數(shù)。Eating t much is bad fr yur health. 吃太多對(duì)你的健康有害。
