more重点语法动词-ing形式和过去分词作宾语补足语1.动词-ing形式作宾语补足语和宾语之间存在逻辑上的主谓关系,强调动作正在进行。常用在catch,feel,find,have,hear,keep,set,observe,see,watch等动词后。Themanwasfiredbecausehehadbeenfoundsmokinginthekitchen.那个人被解雇了,因为他被发现在厨房里吸烟。2.及物动词的过去分词作宾语补足语与宾语有逻辑上的被动关系,表示被动意义或已完成意义,有时候两者兼而有之。不及物动词用作宾语补足语时,与宾语没有逻辑上的动宾关系,只表示动作的完成或状态。WhenIopenedthedoor,Ifoundthegroundcoveredwithsnow.当我打开门时,我发现地面被雪覆盖着。Wemusttakemeasurestokeepnaturebalanced.我们必须采取措施保持生态平衡。Theyfoundalltheguestsgonewhentheywokeup.当他们醒来时,发现所有的客人都走了。WhenIcamein,Isawastrangegirlseatedinthecorner.我进来时看到一个陌生的女孩坐在角落里。注意:(1)在see,watch,hear,observe,lookat,notice,feel等动词后,如果表示经常性的动作或已经完成的动作,要用不带to的不定式。Isawhimbreakintothehouse.我看见他闯入了房子。Weoftenhearhertalkaboutyou.我们经常听到她谈论你。(2)使役动词have,let,make,get后面的非谓语动词作宾语补足语。
