1、新概念 2 学问点总结第一部分、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常常或反复显现的动作；句子中常带有everyday, often, usually, always, sometimes等时间状语；例： When I worked in the pany, I got up early every morning. 在那家公司上班时,我每天早晨都起得很早；In
2、 the past few years she usuallywent touringduringher summerholidays.在过去的几年里,每逢暑假她总是出去旅行；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 once your class
3、mates？ -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确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.When didyoufin
4、ishyourhomework lastnight/thedaybefore yesterday.3. 助动词和情态动词过去式如下：shall should （将要）用于第一人称单数willwould （将要）用于全部人称can could （能,会） may might （可以） must must （必需） haveto had 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,后面的动词仍使用原形；如： I had to do my homework yesterday. 昨天我不得不做作业； 50三、一般过去时态动词变化形式一般过去时态由动词的过去式表示；大多数动词的过去式
5、是在动词原形后加上 ed 构成；这类动词称为规章动词；1） 一般情形下在词尾直接加ed；如： play playedworkworked2） 以 e 结尾的动词只加 d.如： like- likedloveloved3） 以辅音字母 +Y 结尾的动词,变 Y 为 I ,再加 ed.如： study studied carry carried4） 以重读闭音节结尾的动词,假如末尾只有一个辅音字母,要双写最终这个辅音字母,再加 ed.如： stop stopped5） 不以 ed 结尾的过去式,称为不规章动词 , 如：write （写） -wrotego-went do-did have-had
6、see-saw take-took make-made e-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；主语是其次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 over th
7、ere 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：WasWere 主语 表语 其他？这恰巧与动词
8、 be 的一般现在时的疑问句式相像；例如： Were you at home the day before yesterday 前天你在家吗？Was she late this morning今日早上她迟到了吗？更巧的是疑问句的答语也相像,确定回答用“Yes,主语 waswere”；否定回答用“ No,主语 wasnt werent ”；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1Ian Engl

14、since+ 从句（过去时）E.g. Mary has been ill for three days.

40、ill you finish these letters.你什么时候会处理完这些信件？When shall I be expecting you this evening.今日晚上我几点等你？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. Theyhad already had breakfastbefore theyarrivedat the hotel
41、.二、过去完成时的判定依据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；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
42、last Wednesday.2. 由“过去的过去”来判定；过去完成时表示 “过去的过去”,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； 这种用法常显现在：（ 1）宾语从句中要用过去完成时；在 told, said, knew, heard, thought从句；如：She said that she had seen the film before.等动词后的宾语（ 2）状语从句中在时间、条件、缘由、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：当宾语从句的主句为一般过去时
43、,且从句的动作先于主句的动作时,从句When I got to the station, the train had already left. After he had finished his homework, he went to bed.留意： 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,如主、从句表示的动作紧密相连,就主、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 classroo
44、m.（ 3 ）表示意向的动词,如 hope, wish, expect, think, intend, mean, s uppose 等,用过去完成时表示 原本,未能 We had hoped that you would e, but you didnt.3. 依据上、下文来判定；I met Wang Tao in the street yesterday. We hadnt seen each othe r since hewent 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终止,即发生在“过去的过去” ；如：When I woke up, it
