(word完整版)初中现在完成时态的讲解及习题

现在完成时的讲解和练习题一、构成：主语+ have/has + 过去分词+其他否定式:主语+ haven't/hasn't + 过去分词+ 其他。

疑问式:Have /Has + 主语+ 过去分词+ 其他?简略答语: (肯定)Yes, 主语+ have/has. (否定)No, 主语+ haven't/hasn't.二、用法：现在完成时既涉及过去，又联系现在（一）表示过去发生或已经完成的动作对现在造成的影响或结果,也可表示过去已经开始,一直延续到现在的动作或状态常与just（刚刚），already（已经），never（从来没有），ever（曾经），before（以前），yet（仍然，还），once（一次），twice（两次），many times（很多次），how many times（多少次），so far（迄今为止），up to now ,till now 等时间状语连用。

如：※副词的位置：①just常用于肯定句中，放在have / has后，He has just come .②never表示否定,放在have / has后, He has never visited the Great Wall.③ever用于疑问句中,句型为: Have / Has＋主语＋ever＋过去分词？“…曾经……过吗？”用于询问某人过去的经历。

Have you ever been to the farm？（二）：表示过去已经开始，一直延续到现在的动作或状态。

时间状语有：①for＋表示一段时间的词语I have taught English for 19 years。

②since＋表示过去时间点的词语He has been at this school since 1986.③since＋表示过去的时间状语从句I have lived here since I was born.④since＋一段时间＋ago. I have known him since 20 years ago.三、现在完成时态中可以和表示一段时间状语（for，since，how long, all one’s life）连用的动词必须用延续性动词（肯定句）。

如：be，have，know，live，work，study，learn，teach，keep，speak，talk，draw，wait，wear，walk，sleep，drive，write，do，clean等。

非延续性动词，又叫瞬间动词，短暂性动词如begin, start, die, buy, leave, come等，表示动作的发生与结束于一瞬间完成，不能再延续，所以它的现在完成时不能和表示延续的时间状语连用Eg. I have been a teacher for nearly 20 years. How long has he lived here? He has died.常见终止性动词和延续性动词的相应转换形式如下:1、borrow / lend→keep,2、buy→have,3、finish / end→be over,4、begin / start→be on5、open→be open6、close→be closed,7、die→be dead8、arrive /come / go / move / reach /get to→be in /at / be here /be there,9、leave→be away（from）10、go to school→be in school / be a stud ent,11、get up→be up, 12、fall asleep→be asleep 13、fall ill→be ill14、get to know→know, 15、lose→be lost 16、become→be 17、begin to study→study, 18、return / come back / get back→be back 19、join→be in / be a…member,20、join the army→be in t he army /be a soldier21、receive / get a letter→have a letter 22、catch / get a cold→have a coldEg. 他参军已有三年.He has joined the army for three years.（错）改为:He has been in the army for three years / since three years ago.He has been a soldier for three years / since three years ago.四、现在完成时中应注意的几个问题1. have been to和have gone to的区别have been to强调“曾经去过…”，现已不在那里，已经回来了have gone to主要强调的是“去了…”，可能在去的途中，或在去的目的地。

2. have been to和have been in的区别have been to强调人“已回到原地”，后面可接表示“次数”的状语。

have been in表示某人“已在某地停留一段时间，现仍在那里”，其后常带表示一段时间的状语五．现在完成时与一般过去时的区别练习题：I. Fill in the blanks with the proper form.1. I____ already ____ (see) the film.
