15、owns (be used to do：被用来干某事 ) 9.I am not used to getting up early in the morning (beget used to doing： 习惯于干某事) d) 动词 stop，continue，go on，leaveoff 之后，通常用动名词结构作宾语；如果用不定式结构，则不是宾语而是目的状语，相当于in order to。试比较：1.They stopped working 他们停止工作(来做其他事 )。2.They stopped to work 。他们停止 (做其他事 )来工作。3.The students went on
16、 reciting the text 学生们继续背诵课文。4.The students went on to recite the text 学生们停下其他事，继续背诵课文。5.She let off doing the housework 她停止做家务(去干其他事 )。6.She let off to do the housework 她停止 (干其他事 )来做家务。动名词的逻辑主语问题动名词，顾名思义，具有名词的特点，即可以加物主代词和名词的属格来表示其逻辑(这时动名词的逻辑主语与句子主语不一致)。如果动名词的逻辑主语就是句子主语，不用加物主代词或名词的属格。例如：1.The watchm
17、an reported finding the door open = 2.The watchman reported that he had found the door open 此处， finding 的主语与主句主语一致，都是the watchman，所以 finding 前不加物主代词。I appreciated very much your helping me through the tough period. 此处， helping 的主语是you，而主句的主语是I，两者不一致，所以helping 前的物主代词your 不能省略。一般说来， 能带动名词作宾语的动词都可以根据语义
18、意图在动名词之前加上或略去主语。但有些动词，如excuse，forgive，pardon 等，其后的动名词结构总是带有逻辑主语。这些逻辑主语通常由名词或代词宾格表示，也可由名词属格或形容词性物主代词表示。1.I do mind people smoking in public places (名词宾格作逻辑主语) 2.We dont understand him needing so much money (代词宾格作逻辑主语) 3.I will never forgive his betraying me by breaking his promise(物主代词作逻辑主语) 1.Mary excused the boy s upsetting the ink(名词属格作逻辑主语) 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 3 页，共 3 页 - - - - - - - - -
