你看到在賓語(yǔ)后面的是賓補(bǔ).
1) 動(dòng)詞+賓語(yǔ)+不定式(to do) advise allow believe cause challenge compel declare encourage forbid force find hire induce instruct invite like order permit persuade remind request require select send suppose tell train urge 例句：a.Father will not allow us to play on the street.父親不讓我們?cè)诮稚贤嫠?b.We believe him to be guilty.我們相信他是有罪的.Find 的特殊用法：Find 后可用分詞做賓補(bǔ),或先加形式賓語(yǔ),再加形容詞,最后加帶to 的動(dòng)詞不定式.find后也可帶一個(gè)從句.此類動(dòng)詞還有g(shù)et,have.I found him lying on the ground.I found it important to learn.I found that to learn English is important.典型例題:The next morning she found the man ___ in bed,dead.A.lying B.lie C.lay D.laying 答案：A.find的賓語(yǔ)后面,用分詞或分詞短語(yǔ),起賓語(yǔ)補(bǔ)足語(yǔ)作用.現(xiàn)在分詞表達(dá)主動(dòng),也表達(dá)正在進(jìn)行,過(guò)去分詞表達(dá)被動(dòng).2) to + be 的不定式結(jié)構(gòu),作補(bǔ)語(yǔ)的動(dòng)詞.Acknowledge,believe,consider,think,declare(聲稱),discover,fancy(設(shè)想),feel find,guess,judge,imagine,know,prove,see(理解),show,suppose,take(以為),understand We consider Tom to be one of the best students in our class.我們認(rèn)為湯姆是班上最好的學(xué)生之一.典型例題 Charles Babbage is generally considered ___ the first computer.A.to invent B.inventing C.to have invented D.having invented 答案：A.由consider to dosth.排除B、D..此句只說(shuō)明發(fā)明這一個(gè)事實(shí),不定式后用原形即可.而C為現(xiàn)在完成時(shí),發(fā)明為點(diǎn)動(dòng)詞一般不用完成時(shí),且此處也不強(qiáng)調(diào)對(duì)現(xiàn)在的影響,因此不選C.3) to be +形容詞 Seem,appear,be said,be supposed,be believed,be thought,be known,be reported,hope,wish,desire,want,plan,expect,mean… The book is believed to be uninteresting.人們認(rèn)為這本書(shū)沒(méi)什么意思.4) there be+不定式 believe,expect,intend,like,love,mean,prefer,want,wish,undrstand We didn't expect there to be so many people there.我們沒(méi)料到會(huì)有那么多人在哪里.有些動(dòng)詞需用as 短語(yǔ)做補(bǔ)語(yǔ),如regard,think believe,take,consider.We regard Tom as our best teacher.我們認(rèn)為湯姆是我們最好的老師.Mary took him as her father .瑪麗把他當(dāng)作自己的父親.
不定式在句中作定語(yǔ),置于被修飾的名詞或代詞之后,例如The next train（名詞） to arrive is from Washington；Do you have anything （代詞）to say on the question
不定式短語(yǔ)作定語(yǔ)和被修飾詞之間表示以下關(guān)系：(1)表示將來(lái)的動(dòng)作（例①）.(2)與被修飾詞之間有動(dòng)賓關(guān)系,如是不及物動(dòng)詞,則需加介詞（例④）.(3)與被修飾詞之間有動(dòng)賓關(guān)系,同時(shí)與句中其它詞之間又有邏輯上的主謂關(guān)系時(shí),盡管有被動(dòng)含義,卻仍 用主動(dòng)語(yǔ)態(tài)（例③）；如只有動(dòng)賓關(guān)系,而無(wú)邏輯上的主謂關(guān)系,則需用被動(dòng)語(yǔ)態(tài)（例②）.(4)不定式作定語(yǔ)時(shí),一般可轉(zhuǎn)換為定語(yǔ)從句,例①to arrive=that will arrive.
