35、我不饿了)(2)表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止,可能仍然在进行。常带有for和since等表示一段时间的状语。如:He has taught here since 1981.他自1981年就在这儿教书。(可能还要继续教)I havet seen her for four years.我有四年没见到她了。3.结构(1).陈述句结构:主语+have(has)(not)+过去分词+其它。have not=haven,t has not=hasn,t.2).一般疑问句结构:Have(Has)+主语+过去分词+其它?3).特殊疑问句:特殊疑问词+have(has)+
36、主语+过去分词+其它?eg.He has already finished his homework.He hasnt finished his homework yet.Has he finished his homework yet?-Yes,he has./No,he hasnt./No,not yet.(3)表示说话前发生过一次或多次的动作,现在成为一种经验,一般译为汉语“过”,常带有 twice,ever,never,three times 等时间状语。如:I have been to Beijing twice.我去过北京二次。4.现在完成时的时间状语(1)现在完成时属于现在时范围
37、,故不能和过去的时间状语连用。如:yesterdayjast Sunday,in1990,three years ago等。但是,在强调动作产生的后果和影响时,可以和一些 表示不确定的时间状语连用。(2)a.用副词already和yet。already一般用于肯定句中,yet一般用于否定句和 疑问句 中。如:We have already finished our homework.我们已完成作业了。They havent finished their homework yet.他们还没有完成作业。b.用ever和never。多用于否定或疑问句中,表示“曾经”或“从未“等。如:-Have yo

39、today,this morning(month,year,term)等。例 如:-Have you met him today?-No,l havent.今天你见过他吗?我 没有。How many times have you been there this?今年你去过那里吗?(2)现在完成时可以和带有since或for等表示“一段时间”的状语连用,表示动作或状态从 某一时刻开始,一直持续到现在。如:I havent seen him for two years.但是,像come,arrive,buy等终止性动词不能与表示“一段时间”的状语连用。要用,必须改为“be(在)”等延续性动词来表述
40、。现归纳总结一下由非延续性动词到延续性动词的转换:arrivebe heredie be deadleave be awayget up一be upfinish be overopen be openclose be closedborrow keepcatch(a cold)一 have(a cold)begin to study一studybegin(start)一be oncome backbe backfall ill(sick,asleep)一be ill(sick,asleep)go out 一be output on wear 或 be onjoin 一be in 或 be a

42、般过去时都表示在过去完成的动作。但 现在完成时强调的是这一动作与现在的关系。如对现在产生的结果或影响等,而一般过去时 只表示动作在过去某一时刻发生,不表示和现在的关系。试比较:I have lost my new book.我把新书丢了。(现在还未找到)I lost my new book yesterday.我昨天把新书丢了。(昨天丢的,现在找到与否没说明)6.几点注意事项7.(1)have been(to)与have gone(to)的区另U:have been(to)表示“去过某地(现在已经回 来了)”,可用于各人称;have gone(to)表示“去某地了(说话时某人不在当地)”,常用
43、于 第三人称,前者可与once,never,several times等连用,后者则不能如:They have been to Beijing twice.他们去过北京两次。He has gone to Beijing.他去北京了。(2)如单纯表示一段时间,或强调一段时间,虽有since一词,也不必用完成时如:It is two years since his father died.=His father has been dead for two years.他父亲去世已有三年了。(3)终止性动词现在完成时的否定式,已变成一种可以延续的状态,因此可以和表示一段 时间的状语连用。如:I ha
