新概念2知识点总结(共43页)

1、精选优质文档-倾情为你奉上新概念2知识点总结第一部分、时态总结一、一般过去时；一、定义。1. 表示过去的动作或状态，常和明确的过去时间状语连用，如：yesterday, last week, three days ago, in 1998,just now等，或与由when引导的从句连用。2. 也可以表示过去某一段时间内经常或反复出现的动作。句子中常带有every day, often, usually, always, sometimes等时间状语。例：When I worked in the company, I got up early every morning. 在那家公司上班时，我

2、每天早晨都起得很早。In the past few years she usually went touring during her summer holidays.在过去的几年里，每逢暑假她总是出去旅游。二、一般过去时态句子结构1 Be 动词的一般过去时态在没有实义动词的句子中使用be动词， am is 的过去式为was; are的过去式为were.如：I was late yesterday.We werent late yesterday. She wasnt a teacher three years ago.Were you ill yesterday? Were they onc

3、e your classmates？ -Yes, I was. -No, I wasnt.Who were your best friends in your primary school?2. 实义动词的一般过去时态肯定句要使用动词的过去式，否定句和疑问句要使用助动词do和 does 的过去式 did. 如：I went home at nine oclock yesterday. I didnt go home yesterday. He didnt tell me about you. Did you go home yesterday?-Yes, I did. -No, I didnt

4、. When did you finish your homework last night/the day before yesterday? 3. 助动词和情态动词过去式如下：shallshould（将要）用于第一人称单数 willwould（将要）用于所有人称can could（能，会） maymight（可以） mustmust （必须） have tohad to（不得不）助动词和情态动词的过去时态要使用他们的过去式，后面的动词还使用原形。如： I had to do my homework yesterday. (昨天我不得不做作业。) 三、一般过去时态动词变化形式一般过去时态由动

5、词的过去式表示。大多数动词的过去式是在动词原形后加上ed构成。这类动词称为规则动词。1） 一般情况下在词尾直接加ed。 如：playplayed workworked2） 以e结尾的动词只加d. 如：like- liked loveloved 3） 以辅音字母+Y结尾的动词，变Y为I，再加ed. 如：studystudied carrycarried4） 以重读闭音节结尾的动词，如果末尾只有一个辅音字母，要双写最后这个辅音字母，再加ed. 如：stopstopped 5） 不以ed 结尾的过去式，称为不规则动词,如：write（写） -wrote go-went do-did have-had

6、 see-saw take-took make-made come-came buy-bought技巧：巧记一般过去时：【一巧】时间状语（即标志词）巧。一般过去时表示过去发生的动作或存在的状态，恰巧与表示过去的一些时间状语连用。【二巧】形式巧。它与一般现在时一样，形式多样：当主语是第一人称单数或第三人称单数时，谓语动词用was；主语是第二人称或其他人称复数时，谓语动词用were。 例如： I was in the classroom yesterday morning 昨天早上我在教室里。 He was at school last Tuesday 上周二他在学校。 They were ove

7、r there a moment ago 刚才他们在那边。【三巧】否定句结构巧。与动词be的一般现在时一样，它在动词后面加not即可变成否定句，并且was, were与not可以缩写成wasnt, werent。即： 主语 wasnt werent 表语 其他。例如： I was not (wasnt) here yesterday 昨天我不在这儿。 My parents were not (werent) at home last Sunday 上周日我父母不在家。【四巧】 疑问句式巧。把was, were提到句首，句末用问号即可变为一般疑问句。即：Was(Were) 主语 表语 其他？这恰

8、巧与动词be的一般现在时的疑问句式相似。例如：Were you at home the day before yesterday 前天你在家吗？ Was she late this morning今天早上她迟到了吗？更巧的是疑问句的答语也相似，肯定回答用“Yes, 主语waswere”； 否定回答用“No,主语wasntwerent”。 例如：Were Wei Hua and Han Mei here just now 刚才魏华和韩梅在这儿吗？ Yes, they were (No, they werent) 是的，她们在。（不，她们不在。）练习一、用be动词的适当形式填空1I _ an En

13、 finished my homework. He hasnt watered the flowers. Have they watched the film? -Yes, they have. -No, they havent.二用法1、现在完成时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Eg. I have spent all of my money (so far).(含义是:现在我没有钱花了.) Jim has (just/already) come. (含义：吉姆现在在这儿)My father has gone to work.(含义是:我爸爸现在不在这儿) 2、现在完成时可

14、以用来表示发生在过去某一时刻的,持续到现在的动作（用行为动词表示）或状态（be动词表示）常与for（+时间段）,since（+时间点或过去时的句子）连用. for+时段since+过去一个时间点（译为：自从以来）since+时段+agosince+从句（过去时）It is+时段+since+从句（过去时）E.g. Mary has been ill for three days. I have lived here since 1998. 三、现在完成时的标志 现在完成时的含义之一是过去完成的动作对现在仍有影响,用以下四大标志词可以表达这种含义: * 以already, just和yet为标志

16、标+before He has got to Beijing so far.到目前为止他已到了北京。注意：1)现在完成时不能单独与过去的时间状语连用, 如yesterday, last week, three years ago 等; 2)不能与when连用 3)现在完成时往往同表示不确定的过去时间状语连用.四、过去分词变法小结1 、规则动词：规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。 (1)、一般动词，在词尾直接加“ ed ”。 e.g. work-worked-worked (2)、以“ e ”结尾的动词，只在词尾加“ d ”。 e.g. live-lived-live

17、d , (3)、以“辅音字母 + y ”结尾的动词，将 y 变为 i ，再加“ ed ”。 study-studied-studied ,cry-cried-cried (4)、重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加“ ed ”。 stop-stopped-stopped , drop-dropped-dropped 2 、不规则动词：AAA型 E.g. let let let cut cut cutAAB型 E.g. beat beat beatenABA型 E.g. become became become run ran runABB型 E.g. bring bro

40、can see【将来进行时与一般将来时的比较】两者都表示将来的行为，但在用法上有所区别：(1) 将来进行时表示将来某一时刻或某一段时间里正在进行的动作；而一般将来时表示将来某时将要发生的动作。如：She wont be having a meeting in her office at 8:00 tomorrow. 明天8点她不在办公室开会。What will you do at five tomorrow afternoon? 明天下午五点你将干什么？(2) 将来进行时常用来表示说话人设想已经安排好的事；而一般将来时表示临时决定。如：We will be taking our holiday

41、 at the seaside in July. 七月份我们要去海边度假。Did you tell Julia about the result? 你告诉朱莉娅结果了吗？Oh, no.

42、you this evening? 今天晚上我几点等你？五、过去完成时一、过去完成时的概念与结构特点 概念：过去完成时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 ）”。-|- |-|-那时以前 那时 现在 构成：过去完成时由“助动词 had + 过去分词”构成，其中 had 通用于各种人称。 E.g. They had already had breakfast before they arrived at the hotel. 二、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

43、时间状语有： （ 1 ） by + 过去的时间点。如： I had finished reading the novel by nine oclock last night. （ 2 ） by the end of + 过去的时间点。如： We had learned over two thousand English words by the end of last term. （ 3 ） before + 过去的时间点。如： They had planted six hundred trees before last Wednesday. 2. 由“过去的过去”来判定。 过去完成时表示“过

44、去的过去”，是指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。在told, said, knew, heard, thought等动词后的宾语从句。如： She said that she had seen the film before. （ 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。如： When I got to th

45、e station, the train had already left. After he had finished his homework, he went to bed. 注意： before, after 引导的时间状语从句中，由于 before 和 after 本身已表达了动作的先后关系，若主、从句表示的动作紧密相连，则主、从句都用一般过去时。如： Where did you study before you came here? After he closed the door, he left the classroom. （ 3）表示意向的动词，如hope, wish, e

46、xpect, think, intend, mean, suppose等，用过去完成时表示原本，未能We had hoped that you would come, but you didnt.3. 根据上、下文来判定。 I met Wang Tao in the street yesterday. We hadnt seen each other since he went to Beijing.三、过去完成时的主要用法 1. 过去完成时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”。如： When I woke up, it had stopped ra

47、ining. 我醒来时，雨已经停了。（主句的动作发生在“过去的过去”） 2. 过去完成时是一个相对的时态，表示的是“过去的过去”，只有和过去某一时间或某一动作相比较时才使用它。如： He told me that he had written a new book. (had written 发生在 told 之前 ) 3. 过去完成时需要与一个表示过去的时间状语连用，它不能离开过去时间而独立存在。此时多与 already ， yet ， still ， just ， before ， never 等时间副词及 by ， before ， until 等引导的短语或从句连用。如： Before

48、 she came to China, Grace had taught English in a middle school for about five years. Peter had collected more than 300 Chinese stamps by the time he was ten. 4. 过去完成时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。如： By the end of last year, he had worked in the factory for twenty years. （ had

49、 worked 已有了 20 年，还有继续进行下去的可能）四、易混时态辨析1、过去完成时与现在完成时的区别 现在完成时表示的动作发生在过去，但侧重对现在产生的结果或造成的影响，与现在有关，其结构为“助动词 have (has) + 过去分词”；过去完成时则是一个相对的时态，它所表示的动作不仅发生在过去，更强调“过去的过去”，只有和过去某时或某动作相比较时，才用到它。试比较： I have learned 1000 English words so far. 到目前为止我已经学会了 1000 个英语单词。 I had learned 1000 English words till then.到那

50、时为止我已经学会了 1000 个英语单词。 Im sorry to keep you waiting. 对不起，让你久等了。 Oh, not at all. I have been here only a few minutes. 没什么，我只等了几分钟。（“等”的动作从过去某一时间点持续到现在） John returned home yesterday. 约翰昨天回到家的。 Where had he been? 他去哪儿了？（答语中使用过去完成时是指约翰在 returned home 之前去了哪些地方，即“过去的过去”） 2、过去完成时与一般过去时的区别 虽然这两种时态都表示过去发生的动作或

51、存在的状态，但在使用时应注意以下几点：1）. 时间状语不同：过去完成时在时间上强调“过去的过去”；而一般过去时只强调过 去某一特定的时间。试比较： They had arrived at the station by ten yesterday. They arrived at the station at ten yesterday. 2）. 在没有明确的过去时间状语作标志时，谓语动词动作发生的时间先后须依据上下文来判断：先发生的用过去完成时，后发生的则用一般过去时。如： She was very happy. Her whole family were pleased with her, too. She had just won the first in the composition competition. 3）. 当两个或两个以上接连发生的动作用 and 或 but 连接时，按时间顺序，只需用一般过去时来代替过去完成时；另外，在 before ， after ， as soon as 引导的从句中，由于这些连词本身已经表示出时间的先后，因此也可以用过去时来代替过去完成时。如： He entered the room, turned on the light and read an evening paper. I (had
