目录 1现在完成时的构成 (2) 2现在完成时的用法 (5) 3 使用现在完成时需注意事项 (7) 4过去完成时与现在完成时的比较 (12) 练习题 (13) 答案 (16)
现在完成时对于我们来讲是所有时态中最难掌握的一种。因为它并不是表示发生于某一时间的事情，而是既涉及过去，又联系现在的一种时态。请参见下列三个例句： 例：1.I live in Beijing. 我住在北京。 2.I lived in Beijing. 我住过北京。（我在北京住过。） 3.I have lived in Beijing. 我一直住在北京。 例1.的live是一般现在式，表示“我现在住在北京”这一事实。 例2.的lived是过去式。这句只是表示在过去的某一时期我在北京住过，至于现在住不住在北京则不清楚。 例3.的have lived是现在完成时，表示我在过去的某一时间开始住在北京，现在也住在北京。表示从过去到现在的一种继续状态。 1现在完成时的构成 现在完成时的形式是“have （has）+过去分词”，表示继续、完了、结果和经验等四种意思。 现在完成时的否定句是在have（has）的后面加上not，疑问句是将have（has）置于主语之前。 1现在完成时的肯定句 句型：
We have lived in Beijing. 我们一直住在北京。 He has lived in Beijing. 他一直住在北京。 过去分词的三种用法 过去分词有下列三种用法（过去分词的构成详见第六章）：1.构成现在（过去）完成时 have（has）+过去分词～ I have written the letter. 我写完这封信了。 2.被动语态：参见第十三章 be + 过去分词～ He was looked after.他受到照顾。 3.用于形容词 This is a broken chair. 这是一张坏的椅子。 2现在完成时的否定句 句型：主语+have（has）+not +过去分词～.

英语语法完成时篇
完成时篇（一）——现在完成时 [提问] 请问在句子“Working in London has been the best decision I have made so far. （Experiencing English Integrated Book1 Page71）”中，为什么时间状语是完成时的情况下，主句仍然可以使用现在完成时呢？ 答：完成时态通常表示已完成或已经开始从事的动作，它可以分为现在完成时、过去完成时、将来完成时以及完成进行时。根据定义我们可以了解到，除了表示到现在为止动作已经完成或已经开始以外，还有多种情况可以用现在完成时来表达。 一、动作从过去某个时间开始发生，延续到现在，并且说话前已经完成。 例如：The mission has been carried out well.任务已经很好地完成了。 Those girls have eaten two big cakes.女孩们已经吃了两个蛋糕了。 二、某个动作或状态发生在过去，持续并影响现在，有可能会继续保持下去。 例如：My brother has been abroad for several years.我哥哥已经出国好几年了。 It has rained all morning.雨下了一个早晨。 Up to now, parents have accepted the pop music youths prefer to.现在，家长们 已经接受了年轻人喜欢的流行音乐。 I have known him since the summer in 2001.自2001年的那个夏天，我就认识他了。 三、动作发生在现在之前的某个时间，可能是多次动作的集合，也表示习惯性的动作或 状态。 例如：Xiao Qin has come over here three times in the daytime.白天小覃已经来过三次了。 Which countries have you traveled recently?最近你都去过那些国家？ How many papers have you read today? 你今天看了几篇论文？ 四、动作过去曾发生过一次或多次，也可能是一种经历。 例如：Students are very pride that the president has once visited their school. 学生们为总统曾访问过他们学校而骄傲。 Accidents like this have happened more than 20 times these years.这几年此类事故发生不下20起。 在现在完成时态的句子中，常伴随的时间状语有：already，yet，ever，never，just，before，lately，recently，till/until，always，now，since，today; in past years，all morning，all one’s life，up to now，these days，this week/month/year，for a long time。 现在完成时中有几点语法点要注意的： 1）for引出的时间状语只能修饰表示延续性动作的动词。不能用来修饰表示瞬间、短 暂动作或位置转移的动词。如John has come to China for three years，此句错误，come这个动作是短暂性动词，不可能持续发生，因此可改为John has been in China for three years，约翰已经爱中国生活了3年。短暂性动词有appear, begin，borrow，buy，come，close，die，fall，find，finish，join，kill，leave，lend，lose，see，start，stop。 2）在表示时间或条件的状语从句可以用现在完成时表示将来完成的动作。 例如：He will not quit my job until his parents have permitted.父母允许后他才会辞职。 I will arrive at 6 o’clock if the car h as been prepared then.如果到时车准备好了，我能在6 点到达。 3）It is the first/second time that…这个结构中，that从句要用现在完成时。 例如：It is the first time that I have heard of his deeds.这是我第一次听说他的事迹。

初中英语语法过去完成时
【初中语法系列】过去完成时，过去的过去！对于理解过去完成时来说，其要义只有一点，那就“过去的过去”。 一.过去完成时的概念与结构 概念： 表示在过去某一时间或动作之前已经发生或完成了的动作，即“过去的过去（past-in-the-past ）”。 构成： “助动词had +过去分词”，其中had 通用于各种人称。 They had already had breakfast before they arrived at the hotel.在到达旅馆之前，他们已经吃过了早饭。 二.过去完成时的用法 1.表示一个动作或状态在过去某一时间或动作之前已经完成或结束，即发生在“过去的过去”。例如： When I woke up, it had stopped raing. 我醒来时，雨已经停了。（雨停发生在醒来之前，即“过去的过去”） 2.表示某一动作或状态在过去某时之前已经开始，一直延续到这一过去时间，而且动作尚未结束，仍然有继续下去的可能。例如： By the end of last year, he had worked in the factory for twenty years.到去年年底为止，他已经在这个工厂工作了20年。（到去年年底为止已工作了20年，还有继续进行下去的可能） 三.过去完成时的判断依据 1.由时间状语来判定
一般说来，各种时态都有特定的时间状语。与过去完成时连用的时间状语有： （1）by +过去的时间点，例如： I had finished reading the novel by nine o'clock last night. 到昨天晚上九点钟为止，我已经读完了这本小说。 （2）by the end of +过去的时间点，例如： We had learned over two thousand English words by the end of last term.到上学期末为止，我们已经学了两千多单词。 （3）before +过去的时间点，例如： They had planted six hundred trees before last Wednesday. 在xx之前，他们已经植了六百棵树。 2.由“过去的过去”来判定 过去完成时表示“过去的过去”，是指在过去某一动作之前已经发生或完成的动作，即动作有先后关系，动作在前的用过去完成时，在后的用一般过去时。这种用法常出现在： （1）宾语从句中 当宾语从句的主句为一般过去时，且从句的动作先于主句的动作时，从句要用过去完成时。例如： She said that she had seen the film before. 她说她之前看过这部电影。 （2）状语从句中 在时间、条件、原因、方式等状语从句中，主、从句的动作发生有先后关系，动作在前的，要用过去完成时，动作在后的要用一般过去时。例如：
新概念英语第一册73_96课语法点总结
新概念英语第一册73-96课语法点总结 （一）副词的构成及用法 1.构成 a.有些形容词直接在词尾加-ly变为副词 如：careful 小心的 --- carefully 小心地；quick 快的 --- quickly 快地 b.有些以辅音字母加y结尾的形容词，把y变为i，加-ly，如： happy---happily c.有些词的形容词形式与副词形式相同，如：late, hard 如：You are late. 你迟到了。（形容词） I went to bed late yesterday. 我昨天睡得很晚。（副词） It is a hard rock. 这真是一块硬石头。（形容词） She studies hard. 她学习很努力。（副词） 注意：不要将lately及hardly混淆为late及hard的副词。lately译为“最近”；hardly译为“几乎不”，为否 定词。 d.少数以le结尾的形容词变副词时，去掉e加y，如： terrible---terribly; gentle---gently e.以两个l结尾的形容词，直接在词尾加y，如：full---fully 2.用法 副词主要修饰动词，其还可以修饰形容词及副词。
如：He runs quickly. 他跑得快。（副词修饰动词）He is very handsome. 他长得很帅。（副词修饰形容词）He runs very fast. 他跑得非常快。（副词修饰副词） 3.位置 副词修饰动词时，一般放在所修饰动词的后面。 频率副词的位置：Be动词、助动词的后面；实义动词的前面。（口诀：Be助后，实义前） （二）have与have got的用法 1.含义 have和have got都表示“有” 2.用法区别 have可以用在正式或非正式的场景中；have got常用在口语等非正式的场景中。 3.否定形式及疑问形式的区别 a.have为实义动词，变否定及疑问句时需要助动词的帮助 例： 肯定句：I have a book. 否定句：I don’t have a book. 一般疑问句：Do you have a book? b.have got可看成是助动词have加动词的过去分词形式，have 即为助动词
