I haven"t finished my homework yet

答案：realized． 根据题干She"s--（ 意识到 ） she is wrong at this matter，so she feels very sorry．可知句意为：她意识到她在这件事上是错误的，所以她感到非常抱歉．句子中she"s应该是she has 的缩写，可以判断句子应该是现在完成时，由have/has+过去分词构成，realize，动词，意识到，过去分词是realized．故填：realized．

现在完成进行时，是英语中，动词的一种基本时态，其构成为：主语+助动词（have/has）+been+动词的现在分词+其他成分。其表达的意思有两种：1.表示从过去某时开始一直持续到现在的动作，并且还将持续下去。2.表示在说话时刻之前到现在正在进行的动作。现在完成进行时(Present perfect continuous) 　　主语+have（has）been+动词-ing （一）表示从过去某时开始一直持续到现在的动作，并且还将持续下去。 　　The Chinese have been making paper for two thousand years. 　　中国有2000年的造纸历史。（动作还将继续下去） 　　I have been learning English since three years ago. 　　自从三年前以来我一直在学英语。 　　（动作还将继续下去）I study for English since 10 years ago. 　　（二）表示在说话时刻之前到现在正在进行的动作。 　　We have been waiting for you for half an hour. 　　我们已经等你半个钟头了(人还没到，如同在电话里说的，还会继续等) 　　（三）有些现在完成进行时的句子等同于现在完成时的句子。 　　They have been living in this city for ten years. 　　They have lived in this city for ten years. 　　他们在这个城市已经住了10年了。 　　I have been working here for five years. 　　I have worked here for five years. 　　我在这里已经工作五年了。 　　(四）大多数现在完成进行时的句子不等同于现在完成时的句子。 　　I have been writing a book.（动作还将继续下去） 　　我一直在写一本书。 　　I have written a book.（动作已经完成） 　我已经写了一本书。 　　They have been building a bridge. 　　他们一直在造一座桥。 　　They have built a bridge. 　　他们造了一座桥。 　　（五）表示状态的动词不能用于现在完成进行时。 　　I have known him for years. 　　我认识他已经好几年了。 　　 I have been knowing... 　　这类不能用于现在完成进行时的情态动词还有：love爱，like喜欢，hate讨厌，等等在完成时的结构　　现在完成时由“have/has+过去分词”构成，主要有两个含义： 　　①表示动作发生在过去，但与现在的情况有联系，有时无时间状语，有时和一些表示不确定的过去时间状语连用，如：many times，just，yet，ever，never，just，already，before，so far, by now等连用。 　　②表示从过去某一时间开始一直延续到现在并还可能继续延续下去的动作，用于延续性动词，且句中常带有表示一段时间的时间状语，如：since + 时间点/从句，for two months, so far等。 　　二 、1）现在完成时和一般过去时都能表示过去发生过的动作，但现在完成时表示过去动作对现在的影响，并且表示这一动作已完成或还可能继续下去；2）而一般过去时与现在的情况没有联系，仅表示过去的动作，且这一动作到说话时已终止。因此现在完成时不能与表示明确的过去时间如：in1949，yesterday，last week等的状语连用，并且用when或where对这些时间和地点状语提问时，一般只用一般过去时。 　　三、在“it is first/second...time that...。”或在“it/this/that is the +最高级+名词+that...。”结构中，that从句中的动词常用现在完成时；在“it + be ...+since从句”这一结构中，be可用一般现在时或现在完成时，since从句一般用过去时。

The number of people 主语participating in physical fitness program 分词短语作后置定语修饰people has increased 谓语 sharply.状语现在完成时表示过去发生的动作对现在造成的影响或结果（参加……的人数迅速增长）

我放学回家了，就开始玩手机。这个时候妈妈看到了就问我：“Have you finished your homework?”（你作业做完了吗？）做作业是过去的事情，但是妈妈这样问的意思是如果你（过去）作业做完了，才可以玩手机，所以完成作业用现在完成时表达为“have finished”

英语中的动词，是学习中的重点，又是难点。英语中的动词有多种分类法。根据其有无含义，动词可分为实义动词和助动词；根据动词所表示的是动作还是状态，可以分为行为动词和状态动词；根据动词所表示的动作能否延缓，分为延续性动词和终止性动词。 可以表示持续的行为或状态的动词，叫做“延续性动词”，也叫“持续性动词”，如：be, keep, have, like, study, live, etc. 有的表示短暂、瞬间性的动词，叫做“终止性动词”，也可叫“短暂性动词”，或“瞬间性动词”，如die, join, leave, become, return, reach, etc. 终止性动词构成的现在完成时，不可以用表示一段时间的状语（如：since 和for引导的短语）来修饰，终止性动词构成的现在完成时，只表示动作发生的因果关系，不能表示动作的延续，因此不能用表示一段时间的状语来修饰。 如可以说：The Red Cross has already started for the earthquake-stricken area. 但不可说：The Red Cross has already started for the earthquake-stricken area for three days. 因为start是终止性动词, 它所表示的动作短促, 当红十字会出发时，start这个动作便结束了, 不可能延续两天。 在十多年的教学生涯中，发现学生对于如何解决这对矛盾不知所措，下面我来归纳一下解决这对矛盾的四种方法。 1. 用ago时间状语短语来代替since或for引导的时间状语： eg. Mr. Richard has returned from America for two years. (wrong) Mr. Richard has returned from America since two years ago. (wrong) 应改为: He returned from America two years ago. 2．用It is… since…复合句代替简单句 eg. It has been/is two years since Mr. Richard returned from America. 注意：以上两种办法适用于所有终止性动词。 3．用相应的形容词和副词代替终止性动词。 eg. Mr. Richard has been back from America for two years. 4．用延缓性动词代替终止性动词。 eg. He has gone to the Internet for six hours. (wrong) 应改为:He has been on the Internet for six hours. 但须注意：终止性动词的否定式可以和since 或for 引导的时间状语连用。因为终止性动词的否定表示的是一种可以延续的状态。 eg. I have heard from my friend in Africa for half a year. (wrong) I haven"t heard from my friend in Africa for half a year.. (right) 此外，终止性动词与延缓性动词在翻译上也不同，很易混淆。下面我再就终止性动词与延缓性动词的含义问题做一归纳： 1. 在连词since引导的时间状语从句中， 用终止性动词的过去时或用延缓性动词过去时，其含义是大不相同的。 A. since所引导的时间状语从句中，如果句子谓语是终止性动词的过去时， 则从句表示的时间是从“那一时刻开始”。 eg. He has studied very hard since he came to our school. 自从他来校以来，一贯努力学习。 B. 在since所引导的时间状语从句中，其谓语是延缓性动词的过去时，那么从句所表示的时间是从延缓性动词所表示的动作结束时算起。 eg. I haven"t heard any noise since I slept. 自从我醒后，没听见任何声音。 2． 介词for引导的时间状语，在翻译时有两种不同的情况： A．介词for引导的时间状语和延缓性动词的现在完成时的否定式连用时，有两种不同的含义。 eg. He has not lived there for six months. 他不住在那儿已六个月了。（或： 他住在那儿还不到六个月。） B．介词for引导的时间状语和终止性动词的现在完成时的否定式连用，只有一种含义。 eg. Mary has not left here for six months. 玛丽已六个月没有离开过这儿了。 句中含有till 或until 引导的短语或从句，从句中的谓语动词可以是延续性的，也可以是终止性的，但要注意两种情况： 1. 如果主句中动词是延续性的动词，动词肯定或否定都可以，只是含义不同。 eg. He listened to the radio until his father came back. 他听无线电一直到他父亲回来为止。 eg. He didn"t listen to the radio until his father came back.. 直到他父亲回来，他才听无线电。 2. 如果主句中的谓语动词是终止性动词，则只能用否定式。 eg. Mr. Smith didn"t marry until he was forty- five. (right) 史密斯先生到四十五岁才结婚。 Mr. Smith married until he was forty-five. (wrong)参考资料：http://jspd.ew.com.cn/UploadFiles/200597131737804.doc

现在完成时是英文时态的一种现在完成时的用法 have(has)+过去分词(done) 1.现在完成时用来表示现在之前已发生过或完成的动作或状态,但其结果却和现在有联系,也就是说,动作或状态发生在过去但它的影响现在还存在. I have lost my wallet.(含义是:现在我没有钱花了.) Jane has laid the table.(含义是:已可以吃饭了.) Michael has been ill.(含义是:现在仍然很虚弱) He has returned from abroad. (含义是:现在已在此地) 2. 现在完成时可以用来表示发生在过去某一时刻的,持续到现在的情况,常与for,since连用. Mary has been ill for three days. I have lived here since 1998. 3. 现在完成时往往同表示不确定的过去时间状语连用,如already, yet, just, before, recently, lately等: He has already obtained a scholarship. I haven"t seen much of him recently (lately). We have seen that film before. Have they found the missing child yet 4. 现在完成时常常与表示频度的时间状语连用,如often, sometimes, ever, never, twice, on several occasion等: Have you ever been to Beijing I have never heard Bunny say anything against her. I have used this pen only three times. It is still good. George has met that gentleman on several occasions. 5. 现在完成时还往往可以同包括现在时间在内的时间状语连用,如now, up to these few days/weeks/months/years, this morning/week/month/year, now, just, today, up to present, so far等: Peter has written six papers so far. Man has now learned to release energy from the nucleus of the atom. There has bee too much rain in San Francisco this year. The friendly relations and cooperation between our two countries have been enhanced in the past few years. Up to the present everything has been successful. 6. 现在完成时表示现在之前业已完成的动作,虽然其效果或影响仍然存在但已不再继续,但是有一些现在完成时的句子,在后面加上for+一段时间,则现在完成时的动作就表示延续性. Thomas has studied Russian. (现在不再学俄语) Thomas has studied Russian for three years. (=Thomas began to study Russian three years ago, and is still studying it now.(同第2点用法第一个例句) 7. 现在完成时还可以用来表示过去的一个时间到现在这段时间内重复发生的动作. We have had four texts this semester. =================== 现在完成时的“完成用法”和“未完成用法” 1.现在完成时的"完成用法" 现在完成时的"完成用法"指的是动作发生在过去某一时刻并已结束，但该动作对现在产生了影响，与现在情况具有因果关系。 例如：He has turned off the light.他已把灯关了。(动作结束于过去，但说明的是现在的情况--灯现在不亮了。) 现在完成时"完成用法"的特点是动作不延续，因此，该时态只能与表示不定的过去时间状语(如：already，yet，before，recently等)、频度时间状语(如：never，ever，once等)、包括现在时刻在内的时间状语(如：this morning ／ month ／year...，today等)连用。 例如： Have you found your pen yet？你已找到你的钢笔了吗？ 2.现在完成时的"未完成用法" 现在完成时的"未完成用法"指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。 例如：He has lived here since 1978.自从1978年以来，他一直住在这儿。(动作起始于1978年，一直住到现在，可能还要继续住下去。) I have been in the army for more than 5 years.我在部队已经呆了五年多了。(动作开始于5年前，一直延续至今，有可能还要继续下去。) 此种用法的句中常需一个表示一段时间的状语(由since或for引导)，或表示与现在时刻相连的时间状语(如：up to now，so far)等。 例如：I have heard nothing from him up to now.到目前为止我没有他的任何消息。 注意：(1)现在完成时的未完成用法只适用于延续性动词，不可用于终止性动词，即瞬间完成或延续时间很短的动词。如：come，go，arrive，leave，join，become，die等。 (2)现在完成时常见两种句型： ①主语＋have / has been＋for短语 ②It is＋一段时间＋ since从句 例如：He has been in the League for three years.或It is three years since he joined the League. 他入团已三年了 一.have/has been doing sth. 1.现在完成进行时 当后面接有一段时间的词时,或是加表示时间的词时,可以用现在完成时.如果这件事现在还在持续或还在做,则可用 现在完成进行时. 如:I have been skating for 4 hours. I have finished my homework. 2.现在完成时的被动语态. 后接动词的过去分词. 如:The building has been built for 5 years. 二.一般现在时:用动词原形 一般过去时:用动词的过去式 一般将来时:will/shall+do is/am/are going to do 过去将来时:could/would do 现在完成时:have/has done 过去完成时:had done 将来完成时:shall have done 过去将来完成时:would/could have done 现在进行时:is/am/are doing 过去进行时:was/were doing 将来进行时:will/shall be doing 过去将来进行时:would/could be doing 现在完成进行时:have/has been doing 过去完成进行时:had been doing 将来完成进行时:shall have been doing 过去将来完成进行时:would have been doing

laugh的过去分词是 laughed现在完成时态要 have/has laughed如He has laughed for a long time.

have/ has washed

1.quarrel quarrelled quarrels quarrelled quarrelling 2. practise practised practises practised practising 3.belong belonged belongs belonged belonging 4. say said says saied saying 5. forget forgot forgets forgotten forgetting 6.borrow borrowed borrows borrowed borrowing 7.get got gets got getting 8.lend lent lends lent lending 9.finish finished finished finished finishing 10go went goes gone going 11.ask asked asks asked asking 12.find found finds found finding 13.see saw sees seen seeing 14.think thought thinks thought thinking 15.take took takes taken taking 16.watch watched watches watched watching 17.look looked looks looked looking 18.steal stole steals stolen stealing 18.fall fell falls fallen falling 19.feel felt feels felt feeling 20 can could ---- ----- ---- 只要找准规律,其实很好记

现在完成时（The Present Prefect ）是初中阶段一个很重要的时态。现在完成时表示过去发生或已经完成的某一动作对现在造成的影响或结果。既然事情或动作“已经”发生过了，所以在现在完成时句中，通常会出现already（已经），yet（还），just（刚）， for (常用在时间前) 等等。现在完成时的形式是have/has+过去分词，have/has是助动词，没有任何意义。过去发生或者已经完成的某一个动作对现在造成的影响或结果。现在完成时的例句：1、He has turned off the light。他已把灯关了。2、Have you found your pen yet？你已找到你的钢笔了吗?3、He has lived here since 1978。自从1978年以来，他一直住在这儿。4、I have been in the army for more than 5 years。我在部队已经呆了五年多了。

It was the third time that the boy had been late. 2)This is the… that…结构，that 从句要用现在完成时.。 9. 求一篇用现在完成时,和过去完成时写的作文,要快,20;40之前 People said a lot of treasures had been grabbed by them.A good many buildings had been set up in the past.I believe that things will get better and better in the future.I".They have used all kinds of advanced traffic tools to work.People don"m angry with them;t need to go to work on foot.But now great changes have taken place since the invaders were driven off by the Chinese peopleI have ever been to Shanghai for o times.Shanghai is a very beautiful city with a long history.I knew that many imperialist countries had invaded it。 10. 用英语的现在完成时写的作文,60 Last Saturday, my parents and I have driven to an village.

happen 1. 表示“某地(某时)发生了什么事”，常用“sth.+ happen +地点/时间”这一结构来表达，此时主语应是事情。 2. 表示“某人出了某事(常指不好的事)”，要用“sth.+ happen+to sb.”这一结构来表达。 3. 表示“某人碰巧做某事”，要用“sb.+ happen+ to do sth.”这一结构来表达。 4. happen表示“碰巧或恰巧发生某事”时，还可用“It happens / happened that...”这一结构来表达。 现在完成时 1.现在完成时的"完成用法" 现在完成时的"完成用法"指的是动作发生在过去某一时刻并已结束，但该动作对现在产生了影响，与现在情况具有因果关系。 例如：He has turned off the light.他已把灯关了。(动作结束于过去，但说明的是现在的情况--灯现在不亮了。) 现在完成时"完成用法"的特点是动作不延续，因此，该时态只能与表示不定的过去时间状语(如：already，yet，before，recently等)、频度时间状语(如：never，ever，once等)、包括现在时刻在内的时间状语(如：this morning ／ month ／year...，today等)连用。 例如： Have you found your pen yet？你已找到你的钢笔了吗？ 2.现在完成时的"未完成用法" 现在完成时的"未完成用法"指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。 例如：He has lived here since 1978.自从1978年以来，他一直住在这儿。(动作起始于1978年，一直住到现在，可能还要继续住下去。) I have been in the army for more than 5 years.我在部队已经呆了五年多了。(动作开始于5年前，一直延续至今，有可能还要继续下去。) 此种用法的句中常需一个表示一段时间的状语(由since或for引导)，或表示与现在时刻相连的时间状语(如：up to now，so far)等。 例如：I have heard nothing from him up to now.到目前为止我没有他的任何消息。 注意：(1)现在完成时的未完成用法只适用于延续性动词，不可用于终止性动词，即瞬间完成或延续时间很短的动词。如：come，go，arrive，leave，join，become，die等。 (2)现在完成时常见两种句型： ①主语＋have / has been＋for短语 ②It is＋一段时间＋ since从句 例如：He has been in the League for three years.或It is three years since he joined the League. 他入团已三年了。

现在完成时的标志是already、yet、before、just。完成时态的构成分为两部分：一是助动词，二是实义动词的过去分词-ed。具体来说，用助动词have表示“时”，以表明动作发生的时间是在过去、现在还是将来；用过去分词来表示动作的“态”，以表明该动作已经完成。它的构成是：主语+助动词(have/has) +动词的过去分词。（have/has done）扩展资料：基本结构：主语+have/has+动词的过去分词（p.p）1、肯定句：主语+have/has+动词的过去分词(p.p)（V-ed）+宾语（或者其他）.2、否定句：主语+have not/has not+动词的过去分词（p.p）（V-ed）+宾语.3、一般疑问句：Have/Has+主语+动词的过去分词（p.p)（V-ed）+宾语（或者其他）?肯定回答：Yes,I/they/we/you have.或Yes,she/he/人名 has.否定回答：No,I/they/we/you haven"t.或No，she/he/人名 hasn"t.4、特殊疑问句：特殊疑问词+一般疑问句（have/has+主语+过去分词+其他）

你好，我来给你解答一下，仅供参考。■形式：wrap的现在完成时是have(has) wrapped。■例句：I haven"t wrapped her birthday present yet.■拓展：下面是wrap的各种形式变化，帮助你记忆单词、积累单词、运用单词。这些说不定你在学习中会用到。

Where have you been?（不加TO） Where have sb.gone?指还没回来的.

where have you been是现在完成时解析：have+动词过去分词 表示现在完成时态，在上面的句子中是have + been

He lived here in the poast. 过去完成时，过去式，也有可能是现在与其连用的时间状语往往是指一段时间的状语以具体表示某一动作或状态持续了

1.in the past decades 是完成时的标志,只要见到这个词组,谓语就用完成时.2.在含有for的句子中,可能是过去时,可能是现在完成时,也可能是现在完成进行时.如:I stayed in the museum for 8 hours yesterday.我昨天在博物馆呆了8个小时.I have stayed in the museum for 8 hours.我已经在博物馆呆了8个小时了.I have been reading for 8 hours.我已连续看书8个小时了.

has been是现在完成时 表示某一事件到目前为止的状态 隐含着从过去到现在的变化 而一般现在时描述的是客观事实 并无变化可言

这个英语是现在完成时态的

I have borne you for a long time. 我已经忍你很久了！

现在完成时强调动作的结束 have been doing sth即现在完成进行时强调动作的持续假如有for +一段时间 或者since+时间点 短暂性动词要改为延续性动词如 he died two years age he has been dead for two years

so far用于现在完成时,它表示过去发生的动作并延续到现在.如: So far,we haven"t solved the problem. He haven"t achieved any so far.

so far作为习语它有两个主要意思一是表示“到目前为止”，此时它通常要与现在完成时连用； 二是表示“到这种程度或范围”，此时它可以根据具体语境来选用时态，而不一定要与现在完成时连用。 上面这句话的意思是“我只能帮他到这种程度”。 又如：I trust you only so far. 我对你的信任只到这一程度。 请看以下这个表示“到目前为止”的例子： So far the work has been easy but things may change. 到目前为止，这工作很容易，但情况可能有变化。 So far永远要连用现在完成时吗?【 春喜外语 】供稿！春喜外语，学英语告别复读模式，与 真人外教一对一 面对面交谈，不管帅哥还是美女都任你选择。 在线英语培训 ，只要有网络就可以轻松进入学习状态，老师、上课时间、地点你说了算。5年时间12000名学员的共同选择，欲了解更多详情，欢迎咨询在线客服！ 此文章首发于 春喜外语 官网

答案是：sofar的意思是：到目前为止相当于uptonow 用于现在完成时比如：wehavelearnedten englishsongssofar到目前为止我们已经学会了十首英语歌曲

have been in 表示已经呆在某地很久没有have gone in这个结构特别要注意have been to 和have gone to 的区别，前者指已经去过某地，并且已回来；后者指已经去了某地且没有回来或在回来的路上。望采纳~

have been to..."去过某地" I have been to Beijing before.以前我去过北京.have been in.."在某地...（多长时间）..." I have been in Beijing for three days.我在北京有三天了.have gone to..."去了某地还没有回来" where is Tim? He has gone to the library.他去了图书馆（还没回来）

你的比方是过去完成时。现在完成时是对现在造成的影响

since+时间点,for+时间段,already,yet,ever,never,sofar,untilnow,uptonow,recently,thesedays/weeks/years,always,inthelast/past(fewyears)这些词出现时常用现在完成时。也不是特别绝对。希望能帮到你

by now 这时，至此。到如今。 by now直到如今，语气平淡，只是单纯的叙述这件事。till/untill now的语气更强。so far = up to now 到目前为止。要用现在完成时态。till/untill now：当主句是否定句时，它的意思是"直到（某时）（某动作）才（发生）" 这时候常会出现"not until …"的结构如果将 "not until …"的结构放在句首，那么主句要写成倒装句。此两个连词意义相同。肯定形式表示的意思是"做某事直至某时"，动词必须是延续性的。否定形式表达的意思是"直至某时才做某事"。动词为延续性或非延续性都可 以。 正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。 1)Until可用于句首，而till通常不用于句首。 Until you told me, I had heard nothing of what happened. 直到你告诉我以前，出了什么事我一点也不知道。 2)Until when 疑问句中，until要放在句首。 ---Until when are you staying? 你呆到什么时候？ --- Until next Monday. 呆到下周一。 注意：否定句可用另外两种句式表示。 (1）Not until …在句首，主句用倒装。 Not until the early years of the 19th century did man know what heat is. 直到19 世纪初，人类才知道热能是什么。 Not until I began to work did I realize how much time I had wasted. 直到我开始工作，我才认识到了我已蹉跎了几多岁月。 (2) It is not until… that… so far 过去时间持续到现在的动作 并且还有持续的可能与since+过去时间 for+一段时间 by+现在时间 相同 话说这个也不是我自己编辑的答案拉，爱学习的孩子，多去问问老师呐。老师的见解更加正确的说。关键学习英语就是要多积累错题然后反复复习。加油~

有不规则动词表，可以查的

不是。现在完成时是表示的是过去的动作或状态持续到现在并且已经完成。yet是现在完成时的标志，Not......yet表示仍然没有,表示的动作从过去持续到现在仍然没有结束,所以用现在进行时态,不能用现在完成时。

都是begged 吧

1.inthepastfewyears过去几年里接过去时或现在完成时2.theseyears这几年=inrecentyears近几年，接一般现在时，现在进行时，现在完成时3.overtheyearsa.这些年来接现在完成时以上只是一般规律，时态的运用要依据对时态的正确掌握，我对句子的正确理解。希望对你有所帮助。

He often helps his parents do some housework. He is so kind that we all love him very much.

so far 不是指时间，是指距离Jack? Never! He hates driving so far = 杰克？永不！他最讨厌开这么长的距离。是hates因为他是“一直”都讨厌

现在完成时（结构：have+过去分词）(1)现在完成时表示从过去持续到现在的动作或状态现在完成时的这种用法通常与由since或for引导的时间状语连用。如：Theoldmanhavelivedhereformorethantwentyyears.老人已在此住了20多年了。(2)现在完成时表示过去发生的对现在有影响的动作[1]现在完成时的这种用法有时不带时间状语，有时可以和already,before,ever,just,lately,never,once,recently,yet等一些所指时间不具体的时间状语连用。如：HaveyoueverbeentoAustralia?你去过澳大利亚吗？[2]有时现在完成时和now,today,thismorning,thisweek,thisyear等表示现在的时间状语连用。如：Ihaven"tseenhimtoday.我今天没见过他。Ihaveseenhimonlyoncethisyear.我今年只见过他一次。(3)现在完成时在时间和条件状语从句中表示将来完成的动作I"llgotothepartyassoonas(orwhen)Ihavefinishedmyhomework.我完成作业后就去参加聚会。(4)现在完成时和untilnow,sofar,inthepastfewyears,uptothepresent等表示从某时到目前这段时间的状语连用Ihavenotheardfromhersofar.到目前为止，我没有收到过她的信。Wehavelearnedfivehundredwordsuptothepresent.到目前为止，我们已学了五百个生词。但要注意：当意义明确时，适用现在完成时的句子可以不用时间状语。如：Hehasdonealotofwork.他干了许多工作。Shehastoldmeaboutherstory.她跟我讲过她的故事。

sofar在句中出现，谓语动词用现在完成时态：have（has）+动词过去分词。在肯定句中其动词的过去分词需用延续性动词表示动作从过去延续到现在的状态。例如：heleft3yearsago.转换为现在完成时态为：hehasbeenawayfor3years(sofar).在现在完成时态的否定句中：have（has）+not+动词过去分词时。其谓语动词可以用瞬间动词。如：hehasn"tleftforbeijingyet.他还没有去北京

第一句肯定句I have found my pen.疑问句 Have you found your pen?Yes, I have. No, I haven"t.否定句I haven"t found my pen.

时的， so far和现在完成时连用

两句都用现在完成时态没问题啊！so far，可以理解为现在，目前。

是这样：so far的意思为 到现在为止.以此来看,属于完成时应用范畴；但是英语很灵活,一些东西不是固定的,不应学的很死. So far,so good.目前为止,一切顺利. I can only trust him so far.我到现在还信赖他.

Present PerfectFORM[has/have + past participle]Examples:You have seen that movie many times. Have you seen that movie many times? You have not seen that movie many times. Complete List of Present Perfect FormsUSE 1 Unspecified Time Before NowWe use the Present Perfect to say that an action happened at an unspecified time before now. The exact time is not important. You CANNOT use the Present Perfect with specific time expressions such as: yesterday, one year ago, last week, when I was a child, when I lived in Japan, at that moment, that day, one day, etc. We CAN use the Present Perfect with unspecific expressions such as: ever, never, once, many times, several times, before, so far, already, yet, etc. Examples:I have seen that movie twenty times. I think I have met him once before. There have been many earthquakes in California. People have traveled to the Moon. People have not traveled to Mars. Have you read the book yet? Nobody has ever climbed that mountain. A: Has there ever been a war in the United States?B: Yes, there has been a war in the United States. How Do You Actually Use the Present Perfect?The concept of "unspecified time" can be very confusing to English learners. It is best to associate Present Perfect with the following topics:TOPIC 1 ExperienceYou can use the Present Perfect to describe your experience. It is like saying, "I have the experience of..." You can also use this tense to say that you have never had a certain experience. The Present Perfect is NOT used to describe a specific event.Examples:I have been to France.This sentence means that you have had the experience of being in France. Maybe you have been there once, or several times. I have been to France three times.You can add the number of times at the end of the sentence. I have never been to France.This sentence means that you have not had the experience of going to France. I think I have seen that movie before. He has never traveled by train. Joan has studied two foreign languages. A: Have you ever met him?B: No, I have not met him. TOPIC 2 Change Over TimeWe often use the Present Perfect to talk about change that has happened over a period of time.Examples:You have grown since the last time I saw you. The government has become more interested in arts education. Japanese has become one of the most popular courses at the university since the Asian studies program was established. My English has really improved since I moved to Australia. TOPIC 3 AccomplishmentsWe often use the Present Perfect to list the accomplishments of individuals and humanity. You cannot mention a specific time.Examples:Man has walked on the Moon. Our son has learned how to read. Doctors have cured many deadly diseases. Scientists have split the atom. TOPIC 4 An Uncompleted Action You Are ExpectingWe often use the Present Perfect to say that an action which we expected has not happened. Using the Present Perfect suggests that we are still waiting for the action to happen. Examples:James has not finished his homework yet. Susan hasn"t mastered Japanese, but she can communicate. Bill has still not arrived. The rain hasn"t stopped. TOPIC 5 Multiple Actions at Different TimesWe also use the Present Perfect to talk about several different actions which have occurred in the past at different times. Present Perfect suggests the process is not complete and more actions are possible.Examples:The army has attacked that city five times. I have had four quizzes and five tests so far this semester. We have had many major problems while working on this project. She has talked to several specialists about her problem, but nobody knows why she is sick. Time Expressions with Present PerfectWhen we use the Present Perfect it means that something has happened at some point in our lives before now. Remember, the exact time the action happened is not important. Sometimes, we want to limit the time we are looking in for an experience. We can do this with expressions such as: in the last week, in the last year, this week, this month, so far, up to now, etc.Examples:Have you been to Mexico in the last year? I have seen that movie six times in the last month. They have had three tests in the last week. She graduated from university less than three years ago. She has worked for three different companies so far. My car has broken down three times this week. NOTICE"Last year" and "in the last year" are very different in meaning. "Last year" means the year before now, and it is considered a specific time which requires Simple Past. "In the last year" means from 365 days ago until now. It is not considered a specific time, so it requires Present Perfect. Examples:I went to Mexico last year.I went to Mexico in the calendar year before this one. I have been to Mexico in the last year.I have been to Mexico at least once at some point between 365 days ago and now. USE 2 Duration From the Past Until Now (Non-Continuous Verbs)With Non-Continuous Verbs and non-continuous uses of Mixed Verbs, we use the Present Perfect to show that something started in the past and has continued up until now. "For five minutes," "for two weeks," and "since Tuesday" are all durations which can be used with the Present Perfect.Examples:I have had a cold for two weeks. She has been in England for six months. Mary has loved chocolate since she was a little girl. Although the above use of Present Perfect is normally limited to Non-Continuous Verbs and non-continuous uses of Mixed Verbs, the words "live," "work," "teach," and "study" are sometimes used in this way even though they are NOT Non-Continuous Verbs.ADVERB PLACEMENTThe examples below show the placement for grammar adverbs such as: always, only, never, ever, still, just, etc.Examples:You have only seen that movie one time. Have you only seen that movie one time? ACTIVE / PASSIVEExamples:Many tourists have visited that castle. Active That castle has been visited by many tourists. Passive

应该是 has just bought，意思是 “刚刚买回来”，也就是说，购买的行为发生在说话前，而说话时这种购买行为已经成为事实，说明 another garage 属于他自己了，与卖主已经没有关系。

improved句中是与hepled并列的谓语，是一般过去式，“改善”了600多项服务

在scheme后面加has。有了so far，再用一般过去时就不妥。

在过去的两个月内,跟现在相比,肯定要用现在完成时了,表示从过去现在为止对现在造成的影响

I like travelling very much. Beijing is one of the cities i have visited.My stay there is most unforgettable. I have visited many spots of historical interest,such as the Great wall, the Summer Palace, the Palace Museum and Ming Tombs. I was proud of the wisdom and talent of ancient people.I have also been to the Revolution History Museum of China and the Military Museum of China, and i was deeply impressed by achievements our country has made over these years. The trip to Fragrant Hill was extremely exciting. The scenery of red maple leaves all over the hill was so spectacular that I took many photos. The unique cultural tradition and the distinctive natural beauty of Beijing will be a wonderful memory of my life.,5,
