27、动词动作虽然发生在主句谓语动词的动作之前,但因从句中有明确的过去时间状语in1950,所以不用过去完成时态,而用一般过去时态。例 2 The five-year-old girl by her parents.A is looked B has looked forC is being looked for D has been looked解析:该题正确答案为C。在带有介词的动词短语用于被动语态句中,介词不能省,否则就变成了不及物动词短语,而不能用于被动语态的句子中。(五)动词虚拟语气I.要点表示说的话不是事实,或者是不可能发生的情况,而是一种愿望、建议或与事实相反的假设等。一般常用于正式的

43、tting解析:该题选C o不定式to sit o n在句中作定语,修饰名词chair.因为不定式和它所修饰的名词间是“动宾关系”,所以不定式必须是及物动词,故此处o n不能省略。例 2 He was ma d e.A go B gone C going D to go解析:该题选D。make sb.do s th.如果是被动形式,不定式do前的to不能省略。例 3 A new factory is very soon.A to be built B builtC to build D to building解析:该题选A。is to be b u ilt意为”将要被建”。(A)动名词I.要点
44、动名词既具有动词的一些特征,又具有名词的句法功能。1、动名词的形式,以w rite为例。否定式not+动名词2、动名词的用法(1 )作主语Playing football is my favorite sport.Travelling with friends at weekend is fun.作主语的动名词结构复杂且长时,可用i t作形式主语。如:It is fun travelling with friends at weekend.(2)作宾语I enjoy playing PC game.He gave up writing five years ago.(3)作表语W hat he

46、或人称代词的宾格)。无生命名词The girls were afraid of the door suddenly closing.Fire burns better by oxygen being at work.有生命名词,但表泛指。Have you ever heard of girls smoking?两个以上的有生命的名词并列。Do you still remember my parents and me coming to see you thatday?3.后面常接动名词的动词和短语mind,enjoy,finish,consider,practise,magine,keep,s

49、的m e为动名词的逻辑主语(常用于口语中)。(九)分词I.要点分词既具有动词的一些特征,又具有形容和副词的句法功能。它分为现在分词利过去分词两类。现在分词和过去分词的主要差别在于现在分词有一般式和完成式,过去分词则只有一般式。现在分词表动作正在进行,表主动。过去分词及物动词表动作已经完成,表被动。过去分词不及物动词表动作已经完成,表主动。过去分词的句法功能:1、作定语I like to read the novel written by Lu Xun.The woman sitting beside the broken window was a friend of mine.2、作表语Whe
50、n I came into the room,I found the window was broken.Im interested in this book.3、作宾语补足语Tm going to have my bike repaired.When I walked home,I saw the thief caught by the police.4、作状语Seen from the top of the mountain,the city looks small.The teacher came into the classroom,followed by his students.现
