『叁』 初中八年级英语所有语法
现在完成时
1.构成
现在完成时是由助动词 have(has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词,说明句子的意义。
2.用法
(1)表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果。常被just, already, yet 等副词修饰。常与非延续性动词连用。 如:
-Have you had lunch yet? -Yes, I have. I've just had it. 你(已经)吃午饭了吗? 我刚刚吃过。(现在我不饿了)
(2)表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止,可能仍然在进行。常用延续性动词,常带有for和since(自从)等表示一段时间的状语。
如:He has taught here since 1981. 他自1981年就在这儿教书。(可能还要继续教)
I haven't seen her for four years. 我有四年没见到她了。
(3)表示说话前发生过一次或多次的动作,现在成为一种经验,一般译为汉语“过”,常带有twice, ever, never, three times等时间状语。
如: I have been to Beijing twice. 我去过北京二次。
3.结构
1)陈述句结构:主语+have( has)(not)+过去分词+其它。have not=haven’t has not= hasn’t.
2) 一般疑问句结构:Have( Has )+主语+过去分词+其它?
3) 特殊疑问句:特殊疑问词+have(has) +主语+ 过去分词+其它?
e.g. He has already finished his homework.
He hasn’t finished his homework yet.
Has he finished his homework yet? --Yes, he has. / No, he hasn’t. / No, not yet.
4.现在完成时的时间状语
1)现在完成时属于现在时范围,故不能和过去的时间状语连用。如: yesterday, last Sunday, in1990, three years ago等。但是,在强调动作产生的后果和影响时,可以和一些表示不确定的时间状语连用。
a. 用副词already和yet。already一般用于肯定句中,yet一般用于否定句和 疑问句中。如:We have already finished our homework.我们已完成作业了。
They haven't finished their homework yet.他们还没有完成作业。
b. 用ever 和never。多用于否定或疑问句中,表示“曾经”或“从未“等。 如:-Have you ever been to the Great Wall?你曾经去过长城吗?
-I have never been to the Great Wall.我从未去过长城。 c. 用表示到说话为止的过去时间状语,如just(刚刚), before(以前), up to now(直到现在)/ until now, in the past (few years/ three days 等), so far (迄今为止) recently 等。 例如:I have seen her before, but I can not remember where. 我以前见过她,但记不起在哪里见过。
He has been there three times the last few days. 近几年他去过那里三次了。 d.用包括“现在”在内的时间状语,如:today, this morning (month ,year, term等.例如:-Have you met him today? - No, I haven't. 今天你见过他吗?我没有。
How many times have you been there this year? 今年你去过那里多少次?
2) 现在完成时可以和带有since或for等表示“一段时间”的状语连用,表示动作或状态从某一时刻开始,一直持续到现在。如:I haven't seen him for two years. 但是,像come, arrive, buy等终止性动词不能与表示“一段时间”的状语连用。要用,必须改为“be(在)”等延续性动词来表述。现归纳总结一下由非延续性动词到延续性动词的转换:
arrive → be here begin (start) → be on die →be dead come back → be back leave → be away fall ill (sick, asleep) → be ill (sick, asleep) go out →be out finish →be over put on →wear 或be on get up →be up join →be in / be a member of… open → be open close →be closed go to school→ be a student borrow →keep buy →have catch(a cold)→ have(a cold) get to know →know begin to study → study come to work→ work
如:He has been a soldier for three years.他参军三年了。或He has been in the army for there years. 不可以说He has joined the army for there years.
His father has been dead for two years.他父亲去世二年了。(不可以说has died)
The film has been on for ten minutes.电影已开始十分钟了。(不可以说has begun)
We have studied English for three years. (不可以说have begun) 我们(开始)学英语已三年了。
5. 现在完成时和一般过去时的区别
现在完成时和一般过去时都表示在过去完成的动作。但现在完成时强调的是这一动作与现在的关系。如对现在产生的结果或影响等,而一般过去时只表示动作在过去某一时刻发生,不表示和现在的关系。试比较:
I have lost my new book. 我把新书丢了。(现在还未找到)
I lost my new book yesterday. 我昨天把新书丢了。(昨天丢的,现在找到与否没说明)
6.几点注意事项 (1)have been(to)与have gone( to)的区别:have been(to) 表示“去过某地(现在已经回来了)”,可用于各人称;have gone(to) 表示“去某地了(说话时某人不在当地)”,常用于第 三人称,前者可与once ,never, several times等连用,后者则不能。如:They have been to Beijing twice.他们去过北京两次。 He has gone to Beijing . 他去北京了。 (2)“It is或has been + 一段时间+ since引导的时间状语从句”表示“某人干某事已经多长时间了”。since从句的谓语要用非延续性动词 若动词延续,则译成相反的意思。如:It is two years since his father died. =His father has been dead for two years.他父亲去世已有三年了。 It is two years since his father lived here. 他爸爸不住这儿已有三年了。 (3)终止性动词现在完成时的否定式,已变成一种可以延续的状态,因此可以和表示一段时间的状语连用。如:I haven't left here since 1997.自从1997年以来,我一直没有离开过这儿。 (4).提问for短语或since状语用how long。
(5).完成时的否定形式与比较级连用表达最高级含义。如:
I have never seen a better film.我从未看过一部更好的电影。(这部最好)
注:否定式与比较级连用表示最高级含义不一定用于完成时态。如:
--- What about going fishing? --- I can’t agree more.(我再同意不过了哦)
.语法—直接引语变间接引语(多数情况下变为宾语 从句)
(1). 直接引语如果是陈述句,变为间接引语时,用连词that 引导(口语中可以省略引导词)宾语从句。把下列句子变为间接引语或直接引语:

_______________________________________________________
c. They said they would meet at 9:00 p.m. that night.

____________________________________________________.
b. “Tell me the news, please.” Li Hui said to me.

A. not to laugh at B. don’t laugh at C. not laugh at D. never laugh at
2. if 条件句 在一般将来时的句子里(指主句),时间状语从句、条件状语从句等的谓语动词用一般现在时代替将来时。当主句含有情态动词或主句为祈使句时,从句也用一般现在时。如:You must pay for it if you lose it.
附加疑问句
附加疑问句由“陈述句 + 附加疑问句”两部分构成。一般有两种形式:前肯后否或前否后肯。对附加疑问部分应注意以下几点: 1)主语只能用人称代词;2)附加疑问句的not必须与(be /助/情)缩写;3)附加疑问句的时态必须与陈述部分的时态一致。
Tom is a worker, isn’t Tom? (改错) _______ You can swim, can not you? ( 改错) ______

『柒』 仁爱英语八年级上册语法
Unit 1 Playing Sports
Topic 1 What’s your favorite sport?
重点语法
一般将来时:
(一)be going to 结构: ①表示主语进行某一将来行动的打算、意图。这种打算常经过预先考虑并含有自己做好某些准备的意思,因此通常认为用be going to表达的行动很可能会见诸实践。 如:I’m going to play basketball with my classmates this Sunday.
我打算本周日和同学们一起打篮球。
She is going to buy a sweater for her mother.
她打算为她妈妈买一件毛衣。
②表预测。指根据迹象推测,而且马上或很快就要发生。
如:Look at those clouds. It’s going to rain. 瞧那些乌云!快要下雨了!
(二) will + 动词原形:表示单纯的将来事实,常与表将来的时间状语如:tomorrow, soon, later, next time(week/month/year…)等连用。will not = won’t; 缩略形式为’ll.
表示作出立即的决定。这种意图并未经过事先的考虑或计划,是临时的一种决定。
如:a. ----Please put your things away, Tom. 汤姆,把你的东西收拾好。
----I’m sorry. I’ll do it right away. 对不起。我马上就去做。
b. ----Would you like coffee or tea? 您要咖啡还是茶?--I will have a cup of tea,please. 我要一杯茶。c. Don’t worry. I’ll help you. 别担心。我会帮你的。
表示预测。指说话人对于将来的看法、假设和推测。
如: I’m sure our team will win next time. 我确信下次我们队会赢。
Maybe she will go to the gym. 也许她会去体育馆。
表示许诺。如: I’ll do better next time. 下次我会做得更好的。
I’ll visit you tomorrow. 明天我会去看你的。
句式:肯定句:I/She/He/They will go to play baseball soon.
否定句:I/She/He/They won’t go to play baseball soon.
一般疑问句:Will you/she/he/they go to play baseball soon?
回答:Yes, I/she/he/they will. No, I/she /he/they won’t.
(三)动词plan, come, go, leave, fly等用现在进行时表示将要发生的事.
如: I’m coming. 我就来。
He is leaving for Shanghai. 他将到上海去。
We are going to Beijing. 我们将去北京。
5. There be 句型的一般将来时
正:There will be a sports meeting in our school this weekend.
= There is going to be a sports meeting in our school this weekend.
误:There will have a sports meeting in our school this weekend.
= There is going to have a sports meeting in our school this weekend.
四、重点语法
(一) 情态动词: must 与 have to
① must "必须;一定”, 表示有做某一动作的必要或义务,侧重表达说话者的主观看法.(只有一种时态)如:We must wash hands before meals. 饭前我们必须洗手.
We must eat healthy food. 我们必须吃健康的食物.
② have to “不得不,必须”, 侧重表示因客观条件或客观环境的迫使而"不得不做某事".(可用于各种时态)
如:It’s too late. I have to go now. 太迟了.现在我得走了.
I had to borrow some money at that time. 那时我不得不借了一些钱.
*----Must we keep the windows open all the time?---No, we don’t have to. / No, we needn’t. (注意回答时不能用No, we mustn’t.)
1)Are you free this evening? = Do you have time this evening? 你今天晚上有空吗?
三.语法学习
1.I used to listen to rock music but now I collect telephone cards and paintings. (Page 53)
我过去常听摇滚乐,可现在我集电话卡和画。
used to do sth. 这一结构表示过去的习惯(过去经常反复发生的动作)或状态(暗含的意思是现在已不复存在),只有一种形式,即过去式,用于所有人称。used to的否定形式为:used not to do或didn’t use to do。疑问句为Used you to... ? 或 Did you use to...?如:
1)I used to go to school on foot.
我过去步行上学。(暗含的意思是:我现在不再步行上学了。)
2)Mary used to sleep late.
玛莉过去总是很晚才睡觉。(暗含的意思是:玛莉现在睡觉不再那么晚了。)
3)I used to walk along the road after supper.
我过去常常在晚饭后沿着这条马路散步。
4)He used not to like Peking opera, but now he’s very fond of it.
他过去不喜欢京剧,但现在非常喜欢。
现在大多数人在口语中或不太正式的书面语中对否定句和疑问句常使用与do 连用的形式。例如:
1)I didn’t use to like skating, but now I like it very much.
我过去不喜欢滑冰,但现在很喜欢。
2)Did you use to go there?你以往常去哪儿?
3)There used to be a theatre here, didn’t there?以前这里有一座剧院,是不是?
另外,注意be used to doing sth.与used to do sth.的区别:
be used to doing sth “习惯于…,适应于…”如:
1)He is used to working hard. 他习惯于努力地工作。2)He used to bring me roses when he came to see me. 过去他来看我时,常带玫瑰花。
3)I’m used to doing jogging in the morning now. 我习惯于早上慢跑。
be used to do sth.“某物被用来做某事”。如:
1)Wood is used to make paper. 木材被用来生产纸张。
2)Computers can be used to do a lot of work now. 如今电脑可用来做许多事。
2. Collecting stamps must be great fun! (Page 53)集邮肯定很有趣!
must在这里是情态动词,作用是用来表示推测,可以翻译为“想必”。如:
1)Your brother must be in the school. I saw him just now.
你的哥哥想必在学校。我刚才看见他了。
2)Your friend must have left for Nanjing yesterday.
你的朋友想必昨天已经离开去南京了。
3) She thought that her present must be in the box.她以为礼物一定是在盒子里。
4) You must be thirsty after a long walk.走了很长的路,你一定渴了。
5) It must be ten o’clock now.现在肯定有10点钟了。情态动词must的三种否定形式
must表示“必须”时,其否定回答为don’t have to,意思为“不需要”。如:
1)Must I pay back the money right now? No, you don’t have to.
我必须现在偿还这笔钱吗?不,你不需要现在还。2)You must listen to the teacher carefully in class.你必须在课堂上认真听讲。
must表示“推测”时,其否定形式为can’t,意思为“不可能”。如:
1)I’ve seen what she is talking about, so she can’t be telling lies.我目睹了她所说的事情,因此,她不可能在说谎。
2)Yesterday I received a letter from him, so he can’t be here. 昨天我收到了他的信,所以说他不可能在这儿。而must not的意思为“绝对不可,不许,禁止”。如:1)You must not smoke in the hospital.你绝对不可以在医院里吸烟。
2)You must not cross the road when the traffic lights are red.交通灯是红色时,你千万不能过马路。3.He doesn’t mind whether they’re good or not. 他并不介意它们是否是好的。
此句为以whether引导的宾语从句。whether...or not“不论是否……”。如:
1)You have to get up early everyday whether it rains or not.你必须天天早点起床,不论是否下雨。2)Whether we go or not matters little.不论我们是否去,关系不大。
if与whether的区别。
二者在引导宾语从句时一般可换用。如:
1)I want to know if / whether it is going to rain tomorrow.我想知道明天是否下雨。
2) He asked me if / whether Li Ping was at home.他问我李平是否在家。3) He didn’t understand if / whether the stranger told a lie.他不明白那个陌生人是否说的是假话。
但下列几种情况不能换用。
whether 后可紧接or not,而if一般不能。
Let me know whether or not you can come.
你能来还是不能来,请告诉我一声。
whether引导的宾语从句可移到主句前,if则不能。如:Whether this is true or not, I can not say.这件事是否真实,我说不上。
不定式前用whether,不用if。如:I haven’t decided whether to go to the cinema or to stay at home.我还没有决定是看电影还是留在家里。
介词后可用whether,不用if。如:
I haven’t settled the question of whether I’ll go back home.我是否回家还没有定。

ii) 说话人根据已有的迹象认为可能要发生某事. 如: There are a lot of dark clouds. It’s going to rain.

否定句:主语+be + not +going to… eg. I’m not going to the library this afternoon.
一般疑问句: Be +主语+going to… eg. Are you going to play tennis next week?

如: There is going to be a football game tomorrow.
4)与be going to 连用的时间状语有: next week/month/year, tomorrow, the day after tomorrow, this evening, in the future等.

反意疑问句:由陈述句(或祈使句、感叹句)加一个简短问句构成的疑问句叫反意疑问
句。实质是前面陈述句的反问句。一般对应规律:前肯后否;前否后肯。即陈述部分为肯定形式,附加问句用否定形式;陈述部分为否定形式,附加问句用肯定形式。
如:There are many pyramids in Egypt,aren’t there?在埃及有许多金字塔,不是吗?Sally visited the Great Wall last month,didn’t she?萨莉上个月参观了长城,不是吗?He doesn’t realize the importance of saving water,does he?他没有意识到节约用水的重要性,是吗?
特例点拨:①I’m your good friend,aren’t I?我是你的好朋友,不是吗?I don’t think you can rebuild the house,can you?我认为你不能重修这座房子,是吗?(I don’t think…主要在说think后的内容,故按从句变化)。
②陈述部分有nobody,nothing,never,no,few(没几个),little(几乎没有),hardly(几乎不)等否定或半否定词时,仍视为否定句。根据反意疑问句对应规律,疑问部分用肯定形式。如:There is nothing in the room,is there?屋子里什么也没有,是吗?
Maria never surports me,does she? 玛丽亚从未支持过我,是吗?
He had few apples,did he? 他几乎没有苹果,是吗?
③祈使句的反意疑问句:无论肯定或否定,通常在祈使句后加上will you?如:
Please close the door,will you?请关门好吗?
Don’t tear down the old walls,will you?不要拆毁古墙,好吗?
但以Let’s开头的祈使句用shall we?如:
let’s make a survey,shall we?我们做个调查,好吗?
『捌』 英语的祈使句定义
祈使句(Imperative Sentence)是英语中的一个句式,也是用于表达命令、请求、劝告、警告、禁止等回的句子。祈使答句最常用于表达命令,因此在学校文法中也常称为命令句。
祈使句因对象(即主语)是第二人称,所以通常都省略。祈使句的动词都为原型,句末则使用感叹号来表示结束。祈使句无主语 ,主语you常省去。
