44、e 等。注意:感官动词see,hear,watch,observe 等后跟doing 作宾补,表示动作正在进行;后跟do 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 of,look on 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 on my way to school this morning,I saw two women (argue).(2)He was just about to sit dow

48、5)用在 want,wish,like,expect,order 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,notice,feel 等既可以接分词也可以接省略to 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
