初中八大时态归纳复习讲与练.docx

1、初中八大时态归纳复习讲与练初中八大时态归纳复习讲与练（一）一般现在时、一般现在时是英语中应用最广泛的时态之一，是中考复习的重点。它表示1)经常性、习惯性的动作或存在的状态。e.g. I go to school on foot. He is very busy now. 2)表示主语的特征、性格、能力、爱好等。e.g. He can swim. I work hard. I like watching TV. 3)表示客观真理 e.g. There are seven days in a week. The moon moves round the earth. 其结构按正常语序，即“主语+谓

2、语+其它”，有时为了起强调作用，时间状语也可提前. 其句式变化可分为两种情况 1)表示动作， 一般人称作主语的，变否定句须在动词前加助动词dont；变一般疑问句须在句首加助动词do。E.g. They have lunch at 12:00. They dont have lunch at 12:00.Do they have lunch at 12:00?2） 单三人称做主语的，变否定句须在动词前加助动词doesnt；变一般疑问句须在句首加助动词does。E.g. Jenny speaks English very well. Jenny doesnt speak English very

3、well. Does Jenny speak English very well? 含有be动词的要在be上做变化. E.g. Danny is a good student. Danny isnt a good student. Is Danny a good student? 其时间状语为often、 usually、 always、 sometimes等频率副词，on Saturdays、 in the morning(afternoon evening) 、every day 等。 做题时常见错误如下：一、be动词与行为动词同时出现在句子中例：We are plant (plant)

4、the trees in spring.解析：学生往往会用汉语的思维方式去翻译，就成了“我们是在春天植树”。这是学习英语最忌讳的，要看语法是不是正确，在英语中，be是表状态，do是表动作，两种动词不能同时出现在句子中，可记住如下口诀：“英汉语言有差异，be 、do不能放一起，仔细琢磨细分析，语法千万要牢记。”专项练习：一、 单选1 Jenny _ in an office. Her parents _in a hospital.A work works B works work C work are working D is working work2 One of the boys_ a b

5、lack hat.A have B there is C there are D has3 We will go shopping if it_ tomorrow.A dont rain B didnt rain C doesnt rain D isnt rain 4 He said the sun _in the east and _in the west.A rose; set B rises; sets C rises, set D rise; sets5 Wang Mei _ music and often _ to music.A like; listen B likes; list

6、ensC like; are listening D liking ; listen6 Jenny_ English every evening.A has study B studies C study D studied二、填空1 I can take Li Ming there when he _ ( come) to visit.2 _your sister_(know)English?3Her home_ _ _(远离 )her school.4The pot_(not look) like yours very much.5 Where _you_(have)lunch every

7、 day?6 Who_(想要 )to go swimming?7 _she_(do) the housework every day?8 Jenny and Danny usually_(play) games in the afternoon .二、单三人称形式易出错例：1 He plaies (play) football very well. 2 Danny gos (go) to school at 7:10.解析：1以辅音字母加y结尾的动词变单三人称形式才能把y换成i再加es；2与名词变复数不同，变单三人称形式以o结尾的词要加es.三、在句式变换时易出错例：1 Does Jenny

8、has (has) a good friend? 2 Brian doesnt lives (not live) in China.解析：单三人称做主语的一般现在时做句式变化时，可记住如下口诀：“见助动，用原形”。此口诀也可推广用于一般过去时态中。e.g. He didnt go home yesterday.四、对do的理解易出错例：We dont (not do) our homework in the afternoon.答案：dont do解析：do是一个比较难理解的词，它有三个含义: a)是所有行为动词的总称；b)是助动词，无实义；c)是一个具体的行为动词“做，干”。此句中给出的do

9、指“做，干”，not指把此句变为否定句，故须在do前加助动词dont。五、对主语的数判断有误例： Li Ming with me are (be) in Beijing.解析:表面一看是“我和李明两个人在北京”，但with在此做伴随状语，不能做主语，故用is. 了解：另外，宾语从句中，从句部分若是表示客观真理，不管主句是何时态，从句都要用一般现在时；在时间和条件状语从句中，主句表将来，从句要用一般现在时。（二）现在进行时现在进行时表示1、现在（说话的瞬间）正在进行或发生的动作，强调“此时此刻”。E.g. He is reading . They are talking now.2、当前一段时间

10、内的活动或现阶段正在进行的动作。E.g. They are working these days.3、 某些动词的现在进行时，表预定的计划或即将发生的动作。E.g I am coming.其结构为be+现在分词. 现在分词的变法有1、一般在动词词尾加上-ing ,eg. jump2、以不发音字母e结尾的动词，先去e，再加-ing. Eg： have write3、.以重读闭音节末尾只有一个辅音字母结尾的词，它前面是单个元音字母时要先将词尾的辅音字母双写，再加上-ing. E.g. sit put 其句式变换都在be上做文章。E.g. He is buying a bike. Is he buy

11、ing a bike? He isnt buying a bike. 一般由look, listen, now , at this moment等时间状语做标志。尽管现在进行时比较简单，但在做题过程中也常会犯一些错误，常见的错误有如下几种：一 把动词变成现在分词形式易出错例：1、They are swiming.(swim) 2 、Jenny is plaiing(play)football.答案：1.swimming 2 .playing解析：动词变现在分词可有如下口诀:“一添一去y不变”. “一添”指双写规则；“一去”指去掉不发音字母e规则；“y不变”指要与名词变复数区分开。二 丢掉be动

12、词或忘记把动词变成现在分词例：1、 Look,two children flying.(fly) a kite in the park. 2 、Li Mingisnt read ( not read) a book in bed now.答案：1 are flying 2 isnt reading解析:现在进行时肯定句的结构规律为: “be+现在分词,缺一不可”。这一点必须牢记。三 对动词或动词词组提问时丢掉doing例：1 、The students are singing in the room.(对划线部分提问) What are the students in the room?答案：

13、What are the students doing in the room?解析:现在进行时态中对动作提问可记住此句式“What +be +主语+doing+其它?”或简写为“Whatdoing”?句式。四 现在进行时态的选择疑问句中易忽视or后用现在分词形式例：孩子们在跑还是在跳？ Are the children running or jump?答案：Are the children running or jumping?解析: or连接的是两个并列成分，动词形式须一致。专项训练：一 、单选1、 Look! He _their mother do the housework.A. is

14、 helping B. are help C. is help D. is helpping2 、_are the boys doing ? They are singing in the room.A .Who B .How C. What D. Where3、 Dont talk here. My mother _.A. is sleeping B .are sleeping C. sleeping D .sleep4 、Danny _. Dont call him.A. is writeing B .is writing C. writing D .writes5 、When _ he

15、_ back? Sorry, I dont know.A. does, come B. are coming C. is come D. is coming二 、填空1、 Its ten oclock. My mother _(lie)in bed.2、 What _he _(mend)?3、 We _(play)games now.4、 What _you_(do) these days?5、 _he _(clean) the classroom?6、 Who_(sing)in the next room?7 、The girl_(like)wearing a sweater. Look!

16、She _(wear)a red sweater today.（三）一般过去时一般过去时主要表示过去某时发生的动作或情况。可以从以下几个方面来理解：1）过去某个时间所发生的动作或存在的状态。e.g. I bought a new shirt yesterday. He was a worker two years ago.2）过去一段时间内，经常性或习惯性的动作。e.g. When I was a child,I often played with fire. Li Lei always walked to school last term.3）谈到已故人的情况时多用过去时。e.g. Lu X

17、un was a great writer.4）有些发生时间不是很清楚的情况，实际是过去发生的，也应用过去时态。e.g. What did you say? 另外，还可用过去时表示委婉的语气。e.g. Could you lend me your pen? 其结构是主语+动词的过去式。be动词的过去式为was, were；行为动词的过去式有规则变化和不规则变化两种，规则变化有以下几种情况：1）直接在动词原形末尾加-ed. e.g. work-worked; ask-asked; 2）以e结尾的动词只加-d. e.g. arrive-arrived; like-liked.3)末尾只有一个辅音字

18、母的重读闭音节,应先双写这个辅音字母,再加-ed. e.gshop-shopped; 4)以辅音字母+y结尾的动词,先把y变成i,再加-ed. e.g. carry-carried; study-studied.有些动词变过去式是不规则的,e.g. fly-flew; break-broke; teach-taught. 这些需要象生单词一样记住. 其句式变化分为两种情况1)含有be动词的依然在be上做文章. e.g. I was born in 1980. I was not born in 1980. Were you born in 1980? 2)含有行为动词的变否定句要在行为动词前加

19、助动词didnt.,同时把动词变成原形; 变一般疑问句,在句首加助动词did,同时把动词变成原形. e.g. I bought a gift for my mum yesterday. I didnt buy a gift for my mum yesterday. Did you buy a gift for your mum yesterday?其时间状语为yesterday或由其构成的短语,e.g. yesterday morning; 由last+时间构成的短语, e.g. last year; 由时间段+ago构成的短语, e.g. three days ago; 另外,还有on t

20、he morning of Monday, just now等,以及一些表示过去时态的从句.注意,在宾语从句中主句为过去,一般从句也为过去. 常见错误如下:一把动词变成过去式易出错 例: 1 They stoped (stop) talking just now. 2 They plaied (play) football yesterday. 解析:我们可以记住下面的口诀:动词变成过去式,双写规律要牢记;y前若是辅音字,y变i加-ed;y前若是元音字,只须直接加-ed.二 忘记把动词变成过去式 例: I fly (fly) kites on the afternoon of Sunday.

21、答案: flew 解析:我们可以记住下面的口诀:一般过去时态里,过去形式莫忘记.三 在句式变换时易出错 例: 1 We didnt went (not go) out last Friday. 2 Did you had (have) a good time yesterday? 答案: 1 didnt go 2 Did have 解析:请记住口诀见助动, 用原形.四 易与单三人称作主语的一般现在时弄混 例: He taughts (teach) me English last year. 答案: taught 解析:行为动词的过去式无人称和数的变化.即使主语是单三人称,也和其它人称所用动词的

22、形式一样.五 易与现在完成时弄混 例: 我看过这部电影 I saw(see) the film. 答案: I have seen (see) the film. 解析:我看过这部电影说明我了解这部电影的内容,强调现在的情况,应用现在完成时; 一般过去时态的句子只是说明我看了这场电影,与现在无关.六 易与过去进行时弄混。专项练习:一 选择1 She lived there before he _to China. A. came B. comes C. come D. coming2 I _but _nothing. A . was listened; was hearing B. listen

23、ed; heard C . have listened; heard D. listened; heard of3 When did you _here? A. got to B. reached C. arrive in D. reach 4 I _my homework at 7:00 yesterday evening. A. finished B. would finish C. was finishing D. finish5 -He didnt go shopping with you yesterday afternoon, did he?- _. A. No, he doesn

24、t B. Yes, he didnt C. No, he did D. Yes, he did.6 -I have had supper.- When _you _it?A. have; had B. do, have C. did, have D. will have二 填空1 They_(be) on the farm a moment ago.2 There_(be)a shop not long ago.3 Jenny_(not go)to bed until 11:00 oclock last night.4 Danny _(read )English five minutes ag

25、o.5 I _(see)Li Lei _(go) out just now.6 He _(do)his homework every day. But he _(not do)it yesterday.7 When I was young, I _(play)games with my friends.8 When _you_(write)this book? I _it last year.9 Did he_(have) lunch at home?10 I _(eat) the bread, I m full now.(四) 过去进行时过去进行时是表示过去某一时刻或某一时间内正在进行或发生

26、的动作。可以从两个方面来理解：1 过去某一时刻正在进行或发生的动作。E.g. They were playing football atten oclock yesterday morning. My mother was cooking when I got home. I was washing my clothes at this time yesterday. 2 过去某阶段持续进行的动作 What were you doing during the holiday? 另外，在复合句中，若主要动作和背景动作是同时发生的，那么主从句都可用过去进行时e.g. Jenny was readi

27、ng while Danny was writing. 其结构是助动词be的过去形式was/were +v-ing. 其句式变化仍然要在be上做文章。E.g. We were working in class. We werent working in class. Were you working in class? 过去进行时常与过去某一特定时间的状语连用，如 last night, at that time, at noon yesterday, last Sunday 等。 也有时没有时间状语，要通过上下文的暗示来确定用过去进行时。E.g. The students all worke

28、d hard. Everyone knew what he was working for.做题时常见错误如下： 一、易把be+现在分词记成be+过去分词 例：He was talked (talk) to his mum at that time. 答案：was talking 解析：过去进行时与现在进行时结构上的区别体现在be动词上。 二、丢掉be动词或忘记把动词变成现在分词 例：1 I watching (watch) TV when he came in.2 They were play (play) games at 5:00 p.m. yesterday. 答案：1 was wat

29、ching 2 were playing 解析：现在进行时中“be+现在分词,缺一不可”的规律也可应用于过去进行时。三、对动词或动词词组提问时丢掉doing例：We were flying kites at 5:00 p.m. yesterday. (对划线部分提问) What were you at 5:00 p.m. yesterday?答案：What were you doing at 5:00 p.m. yesterday?解析：现在进行时中“Whatdoing”?句式同样适用于过去进行时。四、易与现在进行时弄混例：My mother is cooking (cook)when I got home.答案：was cooking 解析：这两种时态的共同点是都表示动作正在进行，但现在进行时前提是现在，而过去进行时前提是过去，由when I got home可看出前提是过去。五、易与一般过去时弄混例：昨晚我在读一本故事书。
