7.2 不定式作補(bǔ)語(yǔ)
?

   父親不讓我們?cè)诮稚贤嫠!?br>  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(lèi)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: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?,F(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(chēng)), 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.

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 do sth. 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…

注意 : 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。
