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。

in the past 一般用过去式in the past few years in the last 30 years 一般都是现在完成时

现在完成时，你老师没错，我现在做gmat也是跟的现在完成时，虽然不知道为啥。。。

in the past意为在过去，同at lastin the last须加其它名词如in the last placein the last resort

in the last指“上一个”,即过去的一个时间点； 如：in the last week 在上周. in the past可以指一个时间点,也可指时间段. 如：in the past one week,在过去的一周；in the past a few years,在过去的几年中.

used to eg. He lived in Beijing in the past. =He used to live in Beijing . 俊狼猎英团队为您解答,祝开心.

at that time 过去进行时 in the past 一般过去时 at that time 是“在那时”,特指以前的一个时间点、时间段,多用于在叙述一件事情的时候. in the past 是指“在过去”,泛指过去、往日.

因为这个指的是一段时间，而不是具体的过去的某一个时间点如果说是last year,就可以用D

C 试题分析：考查单词意思，exceptional意思“杰出的”，strange意思“奇怪的”，unique意思“独一无二的”，rare意思“罕见的”，句子意思“起飞像火箭着陆像飞机使航天飞机独一无二”，句子是个从句，第一个是引导词what在从句里做主语，是主语从句；第二个是that引导的表语从句，所以选C点评：单词意思是常考内容，平时要多记多积累，遇到单词意思题时，就很容易做出正确选择

一般情况下没有for the past few days 的说法

根据句子的意思：这句话的意思是他们明白了如何把航天飞机从太空发射出去，所以飞机重新回到地球。

in the last years和in the past years 都用现在完成时. in the last years"在最近几年"和in the past years “在过去的几年”,都是截止到“现在”的“几年”.所以跟现在完成时相吻合.

in the past的意思是过去，只要代表过去的都可以，比如yesterday等等

I"ve seen little of her in the past few weeks. 近几周我很少见到她. Most English verbs are inflected with `-ed" in the past tense. 英语大多数动词过去式词尾均变化为-ed的形式. I"ve been there many times in the past. 我从前去过那儿很多次. He has been hounded by his creditors in the past few months. 近几个月来,他一直被债主追债. The totality of such events in the past of an individual or a group. 阅历个人或团体在过去所经历的这样事件的总和

是的。in the past 表示在过去的某一时刻。如果in the past 后面加了时间段的话，则要使用过去完成时。

翻译是相近的，但是时间上有区别in the past：在过去in the last years：在过去几年中

12月23日 liuxue86.com英语频道特为大家准备相关的学习资料，希望对大家有用。 Ladies and Gentlemen, I"d planned to speak to you tonight to report on the state of the union , but the events of earlier today have led me to change those plans. Today is a day for mourning and remembering. Nancy and I are pained to the core by the tragedy of the shuttle Challenger. We know we share this pain with all of the people of our country. This is truly a national loss. Nineteen years ago, almost to the day, we lost three astronauts in a terrible accident on the ground. But we"ve never lost an astronaut in flight. We"ve never had a tragedy like this. And perhaps we"ve forgotten the courage it took for the crew of the shuttle. But they, the Challenger Seven, were aware of the dangers, but overcame them and did their jobs brilliantly. We mourn seven heroes: Michael Smith, Dick Scobee, Judith Resnik, Ronald McNair, Ellison Onizuka, Gregory Jarvis, and Christa McAuliffe . We mourn their loss as a nation together. For the families of the seven, we cannot bear, as you do, the full impact of this tragedy. But we feel the loss, and we"re thinking about you so very much. Your loved ones were daring and brave, and they had that special grace, that special spirit that says, "Give me a challenge, and I"ll meet it with joy." They had a hunger to explore the universe and discover its truths. They wished to serve, and they did. They served all of us. We"ve grown used to wonders in this century. It"s hard to dazzle us. But for twenty-five years the United States space program has been doing just that. We"ve grown used to the idea of space, and, perhaps we forget that we"ve only just begun. We"re still pioneers. They, the members of the Challenger crew, were pioneers. And I want to say something to the schoolchildren of America who were watching the live coverage of the shuttle"s take-off. I know it"s hard to understand, but sometimes painful things like this happen. It"s all part of the process of exploration and discovery. It"s all part of taking a chance and expanding man"s horizons. The future doesn"t belong to the fainthearted; it belongs to the brave. The Challenger crew was pulling us into the future, and we"ll continue to follow them. I"ve always had great faith in and respect for our space program. And what happened today does nothing to diminish it. We don"t hide our space program. We don"t keep secrets and cover things up. We do it all up front and in public. That"s the way freedom is, and we wouldn"t change it for a minute. We"ll continue our quest in space. There will be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space. Nothing ends here; our hopes and our journeys continue. I want to add that I wish I could talk to every man and woman who works for NASA, or who worked on this mission and tell them: "Your dedication and professionalism have moved and impressed us for decades. And we know of your anguish. We share it." There"s a coincidence today. On this day three hundred and ninety years ago, the great explorer Sir Francis Drake died aboard ship off the coast of Panama . In his lifetime the great frontiers were the oceans, and a historian later said, "He lived by the sea, died on it, and was buried in it." Well, today, we can say of the Challenger crew: Their dedication was, like Drake"s, complete. The crew of the space shuttle Challenger honored us by the manner in which they lived their lives. We will never forget them, nor the last time we saw them, this morning, as they prepared for their journey and waved goodbye and "slipped the surly bonds of earth" to "touch the face of God." Thank you. 常识普及：英语演讲稿种类：1。叙述式：向听众陈述自己的思想、经历、事迹，转述自己看到、听到的他人的事迹或事件时使用的。叙述当中，也可夹用议论和抒情。2。议论式：摆事实、讲道理，既有事实材料，又有逻辑推断，立场坚定，旗帜鲜明。3。说明式：对听众说明事理，通过解说某个道理或某一问题来达到树立观点的目的。

可以的。你可以用百度搜 in the past 不可以和现在完成时连用吗?搜索结果的第三个有详细解释我不便发链接，否则会被删除。

不完全相同 in the past是指过去,过去可以很长时间 In the last years,就是最近几年间

in the past 是过去时态时间状语标志。而in the past…years是现在完成时的状语标志。

二者可以替换，意思都是“在过去的两年间”。但是duringthepasttwoyears表示“持续”的意思较为强烈。

都不是，都是过去式标志

　　in the past year的时态用法是英语考试的一个考点，那么你知道in the past year用于什么时态吗?下面是我为你整理的in the past year的时态，希望大家喜欢! 　　in the past year的时态 　　in the past years 　　在过去的几年，用于现在完成时态，表示过去到现在的一段时间。 　　in the last year和in the past few years的区别 　　in the last year在过去的一年中 只用过去时态 很明确的指出时间状态是去年;有时我们也可以直接说last year。 　　in the past few years是 在过去的几年当中，如果语境中发生的动作能延续到现在，对现在有影响，是可以用完成时的。 　　in the past years的例句 　　1. A dozen inmates have absconded from Forest Jail in the past year. 　　去年共有12名犯人从福雷斯特监狱逃脱。 　　2. The cost of living had been racing up in the past year. 　　去年生活费用一直急剧上升. 　　3. The shares have plummeted from 130p to 2.25p in the past year. 　　在过去的一年里，股票已从130便士暴跌到2.25便士。 　　4. Real incomes have gone up by 10 % in the past year. 　　去年实际收入提高了10%. 　　5. Peter has really sprouted up in the past year. 　　彼得过去这一年长高了. 　　6. There have been scores of kidnappings by political extremists in the past year. 　　去年就有政治上极端分子所作的很多起绑架案. 　　7.

答案是：in the pastyears用于一般过去时。 in the past years； 释义：过去几年； 语法：基本意思是“持续”“耐久”。引申可表示“够…之用，使得以维持下去，经受住”等。last常用作不及物动词，不接宾语，也不用于被动结构，通常由介词for引起的时间状语修饰，延续时间短时for可省略。 扩展资料 　　例句： 　　The blogsphere has changed a lot in the past few years. 　　过去几年间博客世界发生了很大变化。 　　一般过去时的辨析： 　　1.一般过去时表示过去某个时间里发生的动作或状态；过去习惯性、经常性的动作、行为。在英语语法中，“时“指动作发生的时间，”态“指动作的样子和状态。 　　2.一般过去时表示在过去某个特定时间发生，也可以表示过去习惯性、经常性的动作。一般不强调动作的影响，只说明的事情。 　　3.一般过去时常与表示过去的时间状语或从句连用。 　　4.表示过去连续发生的`动作时，要用过去时。这种情况下，往往没有表示过去的时间状语，而通过上下文来表示。 　　5.表示在此之前一段时间内经常或反复的动作。 　　6.如果强调已经终止的习惯时要用 used to do（过去常常做，而不那样做了）。 　　7.有些句子，虽然没有表示过去确定时间的状语，但实际上是指过去发生的动作或存在的状态的话，也要用过去时，这一点，我们中国学生往往出错，要特别注意！

In the past ,the houses were small .There aren"t many cars .Many people go for work by bike ,and they often write letters to make friends .The kinds of food are very simple .But now ,the houses are bingger and more comfortable than the past .Cars are more than the past ,so the traffic is crowded .People can send emails or use mobile phone to contact with friends .It"s really convenienter than the past .The food also richer and better ,so people can live longer ,have happiness life .

一般过去式

in the past的意思是“在过去”，所连用的时态有以下几点值得注意：1. 如果是用作时间状语，可连用一般过去时或现在完成时，两者的区别是：用一般过去时，客观地叙述过去的情况；用现在完成时，强调持续到现在的状态或对现在影响。如： In the past he had to read by candlelight. 过去他只得在烛光下攻读。 I"ve been there many times in the past. 我从前去过那儿很多次。 2. 如果是用于名词后作定语，句子时态可根据情况选用。如： He could remember events far back in the past. 他能记得很早以前的事情。 He will never forget his miserable childhood in the past. 他永远也忘不了自己过去的悲惨的童年。

在过去的时间里

在过去，望采纳

在以前

如果是单独的in the past (过去)，一定要用一般过去时。如果是in the past +一段时间，这就表示"在过去的一段时间里"，这就是说从过去到现在这一段时间，因此要用现在完成时态，即: have (has)+过去分词。

在最后在以前

Employersareseekingpeoplewhocancontributeandhavesuccessfullyperformedinthepast.雇主们正在寻找的是能够在过去做出了贡献、表现成功的人们。

in the past 是 指 过去的某个时间 只能与一般过去时 连用in the past 加一段时间 指的是 从现在算起 往前推的一段时间 只能与 现在完成时 连用如 in the past three years ,i have learnt a lot .在过去的三年里 我学到了许多东西

had 已经明确说了是过去式了

in the past-----在过去; 以往; 平昔; 往昔所以用when来提问。例如：I was poor in the past.When were you poor?I walked to school in the past.When did you walk to school?

您好，是的，可以这样使用。如，in the past three years意思是:在过去的三年。

inthepast 有两层含义1、已经结束的往昔，可以与过去时连用，如：Inthepastheassociatedwithactressesandladynovelists. 他过去曾与许多女演员和女小说家为伍。2、刚刚过去的一段时间，可以与现在完成时连用，例如：Mostshopshaveremainedclosedinrthepastdays. 过去几天，大多数商店一直都没有营业。由此可知，用于过去式时表示第一种情况，用于现在完成时表示第二种情况。

一定是要有past啊，否则怎么解释呢？in the few years没有这种说法呀？

英文:Biographical history: Bernard Pares (1867-1949) visited Russia for the first time in 1898. On his return to Britain he began work as a university extension (adult education) lecturer at Liverpool University in 1902. It was at Liverpool in 1907 that he founded the first School of Russian Studies at a British university. Pares was a regular visitor to Russia in the pre First World War period. After the outbreak of World War One he was appointed British Military Observer to the Russian Army and remained at the front for most of 1915-1917. Pares returned to Russia in January 1919 with a commission from the British Government to give lectures in Siberia then held by the White Admiral Kolchak. After Kolchak"s defeat he made his way back to Britain in October 1919. While the British Government awarded him a KBE, the new Soviet Government prevented him from returning to Russia until 1935.Pares returned to his academic career, becoming Professor of Russian Languages, Literature and History at the School of Slavonic Studies (now SSEES) at Kings College in 1919, a post he held until 1939. He was also involved more generally in the development of the School and served as Director of SSEES 1922-1939. In 1922, with Robert Seton-Watson (qv.), professor of Central European history, Pares founded and edited "The Slavonic Review". During the Second World War, Pares along with Robert Seton-Watson, worked for the Government for a short time as Russian specialist for the Foreign Research and Press Service. He then worked for the Ministry of Information, touring Britain to give public talks about Russia, also giving lecture tours in the United States. Pares remained in the United States for the remainder of his life, he died in 1949. He married Margaret Ellis in 1901. They had five children but later separated.

很明显，这是过去时的时间标志，还比如yesterday. last. last year. 等等，表示过去式的时间。

hadoop包括hdfs、mapreduce、yarn、核心组件。hdfs用于存储，mapreduce用于计算,yarn用于资源管理。spark包括spark sql、saprk mllib、spark streaming、spark 图计算。saprk的这些组件都是进行计算的。spark sql离线计算，spark streaming 流计算，spark mllib机器学习。mpi高性能计算。hahoop只有mapreduce是和spark一样用来计算，要比较的话，只能比较mapreduce与spark区别。mapreduce叠代计算中间结果放在磁盘，适合大数据离线计算。spark技术先进，统一使用rdd,结果可放在内存，pipeline，计算速度比mapreduce快。建议大数据存储使用hadoop的hdfs,资源管理用hadoop的yarn,计算使用spark或mpi

inthepast是过去时态意思是在过去inthepast+时间是现在完成时态意思是在刚过去时间里

　　不是的，in the past 是过去式的标志，而 in the last/past +数字+years（在过去的多少年里）是现在完成时的标志。　　例如：　　It was fashionable in the past that women were laced in. 　　在过去，妇女束腰时髦。　　Inthe past, the work in the factory could not move forward for lack of necessaryrules and regulations. 　　过去由于规章制度不健全， 这个厂的工作老是上不去。　　All of the work we do is based on science.

in the past的意思是“在过去”，所连用的时态有以下几点值得注意：如果是用作时间状语，可连用一般过去时或现在完成时，两者的区别是：用一般过去时，客观地叙述过去的情况；用现在完成时，强调持续到现在的状态或对现在影响。如：In the past he had to read by candlelight. 过去他只得在烛光下攻读。I"ve been there many times in the past. 我从前去过那儿很多次。2. 如果是用于名词后作定语，句子时态可根据情况选用。如：He could remember events far back in the past. 他能记得很早以前的事情。He will never forget his miserable childhood in the past. 他永远也忘不了自己过去的悲惨的童年。 ~
