单击此处编辑母版标题样式,单击此处编辑母版文本样式,第二级,第三级,第四级,第五级,*,*,*,现在完成时,第1页,通常使用现在完成时几个情况：,1,表示发生在过去对现在仍有影响动作。,I have read the book.,2,表示过去发生一次或屡次动作。,We have all played football.,3,表示过去开始动作一直延续到现在，只能用于一些带有延续意义动词，常与for,since,so far 等连用。,He has taught here since ten years ago.,第2页,Complete the following sentences with the proper tense.,1 We _(study)English,for about five years.,2 They _(live)in the south,since,their daughter was born.,3 I _(read)your article,three times.,Its well written.,4 The student _(finish)her homework,already.,5 Eric _(go)back to his hometown,today.,6 The police _(,just,finish)searching the area.,have studied,have lived,have read,has finished,has gone,have just finished,第3页,现在完成时与普通过去时区分,：,普通过去时表示发生在过去动作，和现在无关；现在完成时则强调某一发生在过去动作与现在关系，如对现在产生结果或影响等。,He _(work)in the city for ten years.,worked,has worked,第4页,完成以下句子：,I _(see)this film yesterday.（强调看动作发生过了）,I _(see)this film.（强调对现在影响，电影内容已经知道了）,He _(be)in the League for three years.（在团内状态可延续）,He _(join)the League three years ago.（强调加入动作发生在过去）,saw,have seen,has been,joined,第5页,普通过去时还是现在完成时？,1 They _(move)to the south,in 1990,and _(live)there,since then,.,2 Eric _(leave)home,last year,and _(,just,come)back.,3 Justin _(be)away from home,for several days,.He _(disappear),last Friday.,4 They _(buy)this house,three years ago,and they _(live)here,since then.,5 My brother _(go)to see my grandpa,last week.,He _(visit)him,three times this month.,moved,have lived,left,has just come,has been,disappeared,bought,have lived,went,has visited,第6页,现在完成时与普通过去时惯用时间状语：,普通过去时常与详细时间状语连用，而现在完成时通常与含糊时间状语连用，或无时间状语。,普通过去时时间状语：,yesterday,last week，ago,in1980,in October,just now,in the past等，皆为详细时间状语。,现在完成时时间状语：,for,since,already,yet,so far,up to now,ever,never,recently,lately,just,in the past years,等，皆不确定时间状语。,第7页,延续性与非延续性动词：,判断正误：,延续性动词常与for,how long,since 等引导表示一段时间状语或状语从句连用。一些非延续性动词如come,go,leave,die,join,marry 等如用于现在完成时，普通不能够与表示一段时间时间状语连用，此时应改为意义相近延续性动词来表示。,1 He has died for 3 years.,2 He has been dead for 3 years.,3 He died 3 years ago.,4 It has been 3 years since he died.,T,F,F,F,第8页,注意：,非延续性动词否定形式能够与表示延续时间状语连用。即动作不发生状态是能够连续。,判断正误：,（）I have received his letter for a month.,（）I received this letter a month ago.,（）I havent received his letter for almost a month.,错,对,对,第9页,比较since和for：,Since 用来说明动作起始时间，for用来说明动作延续时间长度。比如：,I have lived here for more than twenty years.,I have lived here since I was born.,注意：并非有for 时间状语句子都用现在完成时。,比较：I _(work)here for more than twenty years.（我现在已不在这里工作。）,I _(work)here for many years.（现在我仍在这里工作。）,注意：用句型转换方法，很轻易排除非延续动词在有for/since结构完成时中误用。,1）（）Tom has studied Russian for three years.=Tom began to study Russian three years ago,and is still studying it now.,2）（）Harry has got married for six years.=Harry began to get married six years ago,and is still getting married now.,第二句应改为 Harry got married six years ago.或 Harry has been married for six years.,worked,have worked,对,错,第10页,用于现在完成时特殊句型,1）It is the first/second time.that结构中从句部分，用现在完成时。,比如：,It is the first time that I _(visit)the city.,This is the first time（that）I _(hear)him sing.,注意：,It was the third time that the boy _(be)late.,2）This is+形容词最高级+that结构，that 从句要用现在完成时。,比如：,This is the best film that I _ ever _(see).,经典例题,（1）-Do you know our

D.ever,have come,have visited,have heard,had been,have,seen,B,D,第11页,现在完成时在时间或条件状语从句中使用方法：,完成以下句子：,现在完成时在时间或条件状语从句中能够表示未来。,1.Ill give you the book as soon as I _(finish)it.,2.If you _(see)the film,you will like the director.,have finished,have seen,第12页,Read the diary entry on Page 8 and complete it using the correct forms of the verbs in brackets.,(2)saw (3)has visited(4)loves (5)hasnt visited

tense):（朗诵以下两个句子，说说现在完成时两种使用方法）,现在完成进行时表示某一动作在过去开始发生，已经连续到现在，而且还将连续；或刚才停顿，但与现在相关。,1.I,have been learning,English for three years.,2.He is very tired,because he,has been cleaning,the room.,第14页,Go over
