人教版英语八年级下册Unit 1-5 单元语法知识梳理
Unit 1 单元语法知识梳理一、情态动词should的用法情态动词should有自己的意义，但不能单独作谓语，只能和其他动词一起构成谓语，表示说话人的态度或看法，后接动词原形。
常见用法有以下几点：1.表示劝告、建议等，意为“应该”，常指根据常理认为对的事或应该去做的事。
当劝某人做或不做某事时，常用“should do sth.”或“shouldn't do sth.”。
should 比must 和ought to 语气更加委婉。
例句:You should brush your teeth before you go to bed.你在睡觉前应该刷牙。
You shouldn't watch TV every day.你不应该每天看电视。
2.通常用来表示现在或将来的责任或义务。
例句:Children should obey their parents.孩子们应该听从他们的父母。
We should respect the old.我们应该尊敬老人。
3.表示推断，意为“应该；可能”。
例句:They should be there by now，I think.我觉得现在他们应该都已经到了。
4.用于第一人称疑问句，询问对方的意愿，表示说话人的一种谦逊、客气、委婉的语气。
例句:Should I open the window? 我可以打开窗户吗？What should we do now? 我们现在该干什么呢？5.表示某种感情色彩，意为“竟会”，常用于以how, why开头引导的特殊疑问句中。
例句:Why should you be so early today? 你今天为什么会如此早？二、反身代词1.反身代词的构成反身代词是一种表示反射或强调的代词。
它由第一人称、第二人称的形容词性物主代词和第三人称代词的宾格加词尾-self或-selves构成。
其构成如下表：反身代词与它所指代的名词或代词形成互指关系，两者在人称和数上应保持一致。

人教版八年级下学期英语语法讲解_
人教版八年级下学期英语语法讲解morning.(误) rain为延续性动词，而at eight 表示"点时间"，前后显然矛盾。
如果用延续性动词表示一瞬间的动作，可以借助come, begin, get等终止性动词来表示。
上句可改为：It began to rain at eight yesterday morning.(正)又如：-When did you get to know Jack?-Two years ago.-Then you've known each other for more than two years.-That's right.5、终止性动词的用法特征1.终止性动词可用来表示某一动作完成，因此可用于现在完成时。
如：The train has arrived.火车到了。
Have you joined the computer group? 你加入电脑小组了吗？2.终止性动词表示的动作极其短暂，不能持续。
因此，不可与表示一段时间的状语连用(只限肯定式)。
如：(1)他死了三年了。
误：He has died for three years.正：He has been dead for three years. 正：He died three years ago.正：It is three years since he died. 正：Three years has passed since he died. (2)他来这儿五天了。
误：He has come here for five days.正：He has been here for five days. 正：He came here five days ago.正：It is five days since he came here. 正：Five days has passed since he came here.(1)、(2)句中的die、come为终止性动词，不能与表示"段时间"的状语连用。

3.两种时态的区分
(1)一般过去时的谓语动词用过去式，而现在完成时的谓语基本构成是"助动词have /has +过去分词"。如：The film started at 7 o’clock. He has been a teacher for many years.
析：陈述句部分含否定词never,简略问句部分要用肯定式，又因Kate's是Kate has的缩写，故选B。
2. His uncle has already posted the photos to him. (改为否定句)
His uncle ______ posted the photos to him ______.
4.终止性动词的否定式与until/till连用，构成"not+终止性动词+until/till ..."的句型，意为"直到……才……"。如：You can't leave here until I arrive.直到我到了，你才能离开这里。
樱·Prayer 20:58:44
I will not go to bed until I finish drawing the picture tonight.
二、现在完成时与一般过去时的区别
1.一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作。说话的侧重点只在于陈述一件过去的事情，不强调对"现在"产生的影响。如：
He visited Guilin in 1998.他1998年参观过桂林。(只说明去桂林的时间)
2.现在完成时表示动作发生在过去，对现在造成了影响或产生了结果。不与确定的过去时间状语连用。如：
今天晚上直到我画完画，我才上床睡觉。
5.终止性动词可以用于when引导的时间状语从句中，但不可以用于while引导的时间状语从句中。when表示的时间是"点时间"(从句谓语动词用终止性动词)，也可以是"段时间"(从句谓语动词用延续性动词)。而while表示的是一个较长的时间或过程，从句谓语动词用延续性动词。如：When we reached London, it was twelve o'clock. (reach为终止性动词)
The train has arrived.火车到了。
Have you joined the computer group?你加入电脑小组了吗？
2.终止性动词表示的动作极其短暂，不能持续。因此，不可与表示一段时间的状语连用(只限肯定式)。如：
(1)他死了三年了。误：He has died for three years.
例如：Have you found your pen yet？你已找到你的钢笔了吗？
2.现在完成时的"未完成用法"
现在完成时的"未完成用法"指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。
例如：He has lived here since 1978.自从1978年以来，他一直住在这儿。(动作起始于1978年，一直住到现在，可能还要继续住下去。)
终止性动词也称非延续性动词、瞬间动词或短暂性动词，表示不能延续的动作，这种动作发生后立即结束。如open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy等。
4、延续性动词的用法特征
樱·Prayer 20:58:28
2.延续性动词不能与表示短暂时间的"点时间"状语连用。如：It raind at eight
yesterday morning.(误) rain为延续性动词，而at eight表示"点时间"，前后显然矛盾。如果用延续性动词表示一瞬间的动作，可以借助come, begin, get等终止性动词来表示。上句可改为：It began to rain at eight yesterday morning.(正)又如：
I have been in the army for more than 5 years.我在部队已经呆了五年多了。(动作开始于5年前，一直延续至今，有可能还要继续下去。)
此种用法的句中常需一个表示一段时间的状语(由since或for引导)，或表示与现在时刻相连的时间状语(如：up to now，so far到目前为止)等。
Please look after my daughter while/when we are away. (be away为延续性动词短语)
6.终止性动词完成时不可与how long连用(只限于肯定式)。如：
误：How long have you come here?正：How long have you been here?正：When did you come here?
-Whendid you get to know Jack? -Two years ago.
-Then you've known each other for more than two years. -That's right.
5、终止性动词的用法特征
1.终止性动词可用来表示某一动作完成，因此可用于现在完成时。如：
析：already常用在肯定句中，yet常用在否定句、疑问句中，故填hasn't, yet。
3. -Ann has gone to Shanghai. -So ______her parents. A. has B. had C. did D. have析："so+助/系/情态动词+主语"结构中的动词形式应与前句结构中动词形式保持一致，又后句的主语为her parents是复数,故选D。
(2)现在完成时常见两种句型：
①主语＋have / has been＋for短语
②It is＋一段时间＋since从句
例如：He has been in the Ls since he joined the League.他入团已三年了。
现在完成时"完成用法"的特点是动作不延续，因此，该时态只能与表示不定的过去时间状语(如：already，yet，before，recently等)、频度时间状语(如：never，ever，once等)、包括现在时刻在内的时间状语(如：this morning／month／year...，today等)连用。
(2)一般过去时通常与表示过去的时间状语连用。如：yesterday, last week, two years ago, just now, in 2002等；而现在完成时则常与just, already, ever, never等副词和these 3
days, this week, since..., for...等表示一段时间的状语连用。
3、延续性动词和终止性动词的概念
英语中，动词按其动作发生的方式、动作发生过程的长短，可分为延续性动词和终止性动词。
延续性动词表示能够延续的动作，这种动作可以延续下去或产生持久影响。如：learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。1

(UNIT1)现在完成时的重点和难点
一、现在完成时的“完成用法”和“未完成用法”
1.现在完成时的"完成用法"
现在完成时的"完成用法"指的是动作发生在过去某一时刻并已结束，但该动作对现在产生了影响，与现在情况具有因果关系。例如：He has turned off the light.他已把灯关了。(动作结束于过去，但说明的是现在的情况--灯现在不亮了。)
三、现在完成时考点例析
现在完成时是较难掌握、中考考查较多的时态。涉及的考点有：
樱·Prayer 20:58:59
一、考查其构成
"助动词have (has) +动词过去分词"构成现在完成时。如：
1. Kate's never seen Chinese films，____ ? A. hasn't she B. has she C. isn't she D. is she
1.延续性动词可以用于现在完成时，其完成时态可与表示"段时间"的状语连用。表示"段时间"的短语有：for two years, during the past three years, since last year, how long等。如：I have learned English since I came here.自从我来到这儿就学英语了。
看看以下的几组句子，有什么区别？① Have you seen the film?(A) Did you see the film?(B)
[说明]你看过这部电影吗？(A)句强调的是被问者对剧情是否了解；(B)句强调的是看这部电影的动作是否发生过，并不强调是否知道其内容。
② How has he done it?(A) How did he do it?(B)
(1)将句中终止性动词转换为相应的延续性动词，如上面两例中的第一种正确表达方式。下面列举几例：leave→be away, borrow→keep, buy→have, begin/start→be on, die→be dead, move to→live in, finish→be over, join→be in/be a member of, open sth.→keep sth. open, fall ill→be ill, get up→be up, catch a cold→have a cold。
