单元语法现在分词和过去分词作宾语补足语要点一 现在分词作宾语补足语宾语与宾补是主动关系。其主要用于以下两类动词后作宾语补足语: ( 1)位于感官动词后:如 see,hear,feel, smell,watch,catch(当场发现),find, listen t,lk at,ntice,bserve 等。注意:感官动词see,hear,watch,bserve 等后跟ding 作宾补,表示动作正在进行;后跟d 作宾补,表示动作的全过程。( 2)位于使役动词后: 如set,keep,have,get,leave 等。◆学法点拨在有些动词(短语),如regard,describe, accept,think f,lk n 等之后,可由as 引出动词-ing 形式作宾补。
单句语法填空(1)When I was n my way t schl this mrning,I saw tw wmen (argue). (2)He was just abut t sit dwn when he felt smething (mve) near his feet. (3)On the bank f the river,we fund him (lie)n a bench,with his eyes _______ (fix)n a kite in the sky. (4) I std n the bridge and watched bats (pass)by.

(8) A ck will be immediately fired if he is fund (smke)in the kitchen. (9) When I came in,I saw Linda (whisper)t Danny.
being perfrmed
whispering
要点二 过去分词作宾语补足语过去分词作宾语补足语说明宾语的性质或状态,宾语与过去分词之间为被动关系,即宾语是过去分词动作的承受者。能够接过去分词作宾语补足语的动词主要有两类:一类是感官动词,另一类是使役动词。在高中阶段学习的过去分词作宾语补足语的情况通常有以下几种: (1)用于表示某种状态的动词 keep, leave 等的宾语的后面(2)“have/get+ 宾语 + 过去分词”表示 “ 让别人做某事”或“遭遇某种不幸”。 (3)在“make+ 宾语 + 过去分词”结构中 过去分词表示结果。(4)常用在感官动词 watch,see,hear,ntice,feel 等的后面作宾语补足语;此外,find 也有此用法。(5)用在 want,wish,like,expect,rder 等表示“希望、愿望、命令”的动词的后面作宾语补足语。(6)在“with+ 宾语 + 过去分词”结构中, 宾语与过去分词之间是被动关系。
◆误区警示现在分词、过去分词、动词不定式作宾语补足语的判断标准: (1)用哪种形式根据宾语和宾补之间的关系来确定用哪种非谓语动词形式。主动关系——现在分词被动关系——过去分词(2)感官动词后的宾补感官动词hear,see,ntice,feel 等既可以接分词也可以接省略t 的动词不定式作宾补。现在分词——主动、进行的动作过去分词——被动、完成的动作动词不定式——动作的全过程
单句语法填空(1) He is very ppular amng his students as he always tries t make them (interest)in his lectures. (2) When we saw the rad (blck)with snw,we decided t spend the hliday at hme. (3) The judges gave n hint f what they thught,s I left the rm really (wrry)(4) Befre driving int the city,yu are required t get yur car (wash).
