30、 Jack/Jacks(him/his)coming here.,2.逻辑主语是无生命的名词：只用名词普通格。Is there any hope of our team winning the match?3.逻辑主语是指示代词或不定代词 this,that,somebody,someone,nobody,none,anybody,anyone时，只有普通格。She was disturbed by somebody shouting outside.,动名词的时态和语态1）动名词的时态：一般式和完成式如G.的动作没明确表示出时间是与谓语同时发生或在谓语之前发生，用一般式。We are int

34、ken.The glass was broken by Tom.（被动语态）,2.现在分词和过去分词作状语的区别：分词与逻辑主语（即句子主语）关系来决定分词的语态，主语能发出分词的动作,用主动doing/having done，不能发出分词的动作,用被动 done/having been done。作状语时，可表示时间，原因，结果，条件，方式，伴随状况。分词的动作如发生在谓语动词之后doing，用一般式，如发生在谓语动词之前，用完成式having done。,注1：分词作状语时，其逻辑主语须与句子的主语一致，构成主动或被动的关系。注2：表示时间关系的分词短语有时可由连接词while或when引

35、导。注3：有时，”with+名词（或代词宾格）+分词”的结构表示伴随状况。注4:当分词的逻辑主语与主句的主语不同时，分词需有自己的主语，构成独立主格结构。（见后）,A)1._(see)those picture,he couldnt help thinking of those days in Yanan.2._(turn)round,Fanny found a bus driving up.3._(water)the vegetables,they began to pick up the apples.4._(finish)the work,he went back home on foo
