gone.(她走了。)从这句话中动词所用的现在完成时态可以看出“走”的动作是过去发生的，而对现在所造成的结果是她不在这里了。,He speaks French so fluently.He learned it in Paris.He was there for two years.He has studied French.(他学过法语。)这句话所说明的结果是他现在懂法语。,Look!The blackboard is so clean now.He has cleaned the blackboard.(他已经擦过黑板了。)这句话所表示的结果是黑板现在是干净的。,定义2：现在完成时态还表示动作或状态从过去开始一直延续到现在甚至将来。,Mike borrowed the books two days ago.,Mike has kept the books for two days.,二、现在完成时的构成1.现在完成时的肯定句句型 主语（第一、二人称单、复数)+have 主语（第三人称复数）+have+过去分词 主语（第三人称单数）+has,2.现在完成时的否定句句型 主语+have/has+not+过去分词+I have not seen the movie yet.He hasnt been to Beijing since then,We have lived in Beijing.He has lived in Beijing.I have finished my homework.,3.现在完成时的一般疑问句句型 Have/Has+主语+过去分词+.Have you finished the work?Has she arrived here?4.现在完成时的特殊疑问句句型 特殊疑问词+have/has+主语+过去分词+.How many times

finished,Have,been,have,seen,has,cleaned,have practiced,注意：当在肯定陈述句中含有already或just 时，在转换成否定句或疑问句时，要把句中的already 或just 去掉，在句末加上yet.,I havent seen the film yet.,2 I have done my homework already.,I havent done my homework yet.,3.Mother has just cleaned the house.,Mother hasnt cleaned the house yet.,1 I have seen the film already.,标志词（2）：这种用法还可与 for+一段时间,since+过去的时间点,these years,so far,in the past/last years等连用,1.We _(learn)English for three years/since two years ago/since 2000.2.Mr.Green _(be)in China these years.3.They _(write)15 songs so far.4.The population _(grow)more slowly in the past ten

seven years ago.3.Since+从句（此时 since充当连词）（此时主句使用完成时，从句则要使用过去时）Eg:I have lived here since I was born.4.当主句的谓语动词为be或seem时，则主句要采用一般现在时,从句仍使用过去时。Eg:Its a long time since we left school.,for or since,1.We have lived here _ 1990.2.How long have you studied here?_ 5 years.3.The boy has had a bad cold _ last night.4.Mr.Huang has kept the books _ a week ago.5.I have taught in the school _ I came here.6We

years.,（说明他还继续学下去）,（只说明他过去学过五年英语，但现在不学了。）,一般过去时与现在完成时有一些明显的时间状语：,遇到yesterday,Last year,in May,in+过去某一年，two days ago,just now等就用一般过去时。,当有 so far,in the past/last few
