(完整word版)八年级英语语法点及重点短语

1、八年级重点语法句型语法：1、动词1)情态动词(modal verbs)情态动词可以用来表示“提议”、 “建议”或“请求”等。情态动词should 作“应该；应当；可以”讲，用以表达职责和义务、提出劝告，而且表述的是自己的主观看法。其后动词接原型。例如：a 用于表示 应该 或 不应该的概念。此时常指长辈教导或责备晚辈。例如：You should be here with clean hands 你应该把手洗干净了再来。b 用于提出意见劝导别人。例如：You should go to the doctor if you feel ill.如果你感觉不舒服，你最好去看医生。c 用于表示可能性。sho

2、uld 的这一用法是考试中常常出现的考点之一。例如：We should arrive by supper time. 我们在晚饭前就能到了。She should be here any moment.她随时者 B 可能来。情态动词could 用于有礼貌地向对方提出要求或请求。a. 表示“能力”或“可能性”，作为 can 的过去形式。如：Could you speak English then？那时你能讲英语吗？He said he couldnt follow me. 他说他跟不上我。b. 表示惊异、怀疑、不相信等情绪。如：Who could have taken them？谁会把它们拿走了呢

3、？She couldnt have left so soon. 她不可能这么快就走了。在这种情况下，could和can是可以换用的，用could时口气较缓和，用can时不 相信的程度更强一些，两者在时间上没有差别。c. 比较委婉客气地提出问题或陈述看法。如： Could you let me have your passport? Yes, here it is.看看你的护照好吗？行，这就是。I could come earlier, if necessary.如果必要我可以早点来。这时could和can没有时间上的差别。2、过去进行时(past progressive tens)e1)过去进

4、行时的定义过去进行时主要表示过去某一时刻正在进行的动作，或表示过去某一阶段一直在进行的动作。如：I was having a talk with Li Hua at that time. 那时，我正在跟李华谈话。I was watching TV at home last night. 昨晚我一直在看电视。2)过去进行时的结构过去进行时由“was / were + 现在分词”构成。如：I was doing my lessons then.那时，我在做功课。We were cleaning the house.我们在打扫房子。3)使用过去进行时应注意的几点(1) 过去进行时可表示按计划、安排过

5、去某时刻将要发生的动作。如：He said they were leaving for Beijing this afternoon. 他说他今天下午要去北京。(2)动词hope, wonder等的过去进行时常用来表示提出要求，虽然表示现在的内容，但语气比一般现在时或一般过去时要委婉。如：I was wondering whether you could come to join us. 我想你能否过来跟我们一起活动 ?(3)过去进行时中有 always, forever, continually, constantly修饰时，表示说话 人的赞赏或厌烦的感情。如：He was always t

6、hinking of others. 他总是想到人家。3、现在完成时(present perfect tense)1)表示截止现在业已完成的动作By now, I have collected all the data that I need到现在为止，我已收集到了我所需 的全部资料。She has read 150 pages toda她今天已看了 150 页。We havent met for many years我们已多年没见了。They have developed a new product们研制成功了种新产品。2）表示发生在过去而对现在产生影响、带来结果的动作Have you ha

8、both and:表示“两者都”。注意：当bothand连接主语时，后面动词一般要用复数。如：Both Lily and Lucy are right.not only but also: 不仅而且”。注意：后面动词采用就近原则，与but also后的词保持一致。如： Not only my parents but also my brother likes the cat. either-or: 或者或者”。注意谓语动词采用就近原则。如：Either youor I am wrong. neither-nor: “既不也不 是“eitheror的否定形式。谓语动词采用就近原则，与nor 后的

9、词保持一致。如： Neither you nor he is right.4、状语从句状语从句专题句法重点状语从句是中考词汇和句法部分考查的重点内容之一。状语的功用：状语说明地 点、时间、原因、目的、结果、条件、让步等在复习状语从句时,主要任务是弄清楚引导各种状语从句的连词的用法。现就主要考查点简述如下:1 .引导时间状语从句的连词主要有 when, while, as, by the time, before, after, since, till/until, as soon a等。其中when while和as都可表示当时候，但用法有区别：when意为在时；当时，可表示点时间或段时间，从

10、何谓语可以是终止性动词,也可以是延续性动词。例如:When I got home, he was having supper.as意为边边或与同时，重在表示两个动作同时发生。伴随 进行。as从何是终止性动词时，主句通常也必须是终止性动词。例如：They sang as they danced. while 只可表示 段时间,从句谓语只限于延续性动词。例如:While I was sleeping, my father came in.注:从何谓语是持续性动词时，when、while和as可以互换2 .引导原因状语从句的连词原因状语从句一般由 because,since, as, for 弓I导

11、印意 as,because,since口 for的区别 :如果原因是构成句子的最主要部分，一般用because because引导的从句一般不放在句子的开头。例如:I missed the train because I got up late.注:对于以why开头的问句，一般只能用because导的从何来回答。如果原因已为人们所知，或不如句子的其余部分重要，就用as或since since 比as稍微正式一些。as和since引导的从旬一般放在句子的开头。例如：As he was not well,I decided to go there without him.Since this me

12、thod doesnt work, lets try another. for 表示所说的理由是一种补充说明, 因此,for 引导的从句可以放在括号里,而且 for 引导的从句一般不放在句子的开头。例如:I decided to stop and have lunch, for I was feeling quite hungry.3 .引导结果状语从句的连词主要有 so/such that,so that 等。1) sothat结构在某种情况下可以与 enough to和tooto结构相互转换。例 如:She is so short that she cant reach the butto

13、ns of the lift. =She is too short to reach the buttons of the lift.2)so that也可以引导结果状语从何，意为”结果是；以致于。例如：They missed the bus so that they were late for class. sothat.：句型的意思是“如此/这么以致于”，常引导结果状语从句，但“sothat”是个爱”变脸”句型，你一不留意就会出错。 “ so.that.”句型及其转换也是中考的热点，现将其用法总结归纳如下，让我们一起来看看它是怎样变的吧。注意：sothat.句型中的so是副词，常常用来修饰

14、形容词或副词，常用句型为： 主语+谓语+so+adj. / adv. + that从旬。例如：1. he is so young that she cant look after herself.2. The boy ran so fast that I couldnt catch him.3. He was so angry that he couldnt say a word.在“suchthat.句型中，such修饰名词，意思也是“如此以致于”但当名词前有many、 much、 (a) few、 (a) little 等词修饰时，句子中要用“ so.that.”而不能用“such.tha

15、t.”. 。例如：1. He has so much money that he can buy what he wanted.2. Ive had so many falls that I have pains here and there.3. There is litte water in the glass that I cant drink any more.4. 引导目的状语从句的连词so that也可引导目的状语从句，此时可用to或in order to替换，将其改为简单句。例如 :He got up early so that he could get to school on

16、 time. =He got up early to get to school on time. =In order to get to school on time,he got up early.5. 引导让步状语从句的连词though, although注意： 当有though, although时，后面的从何不能有 but,但是though和yet 可连用Although its raining, they are still working in the field.虽然在下雨，但他们仍在地里干活。He is very old, but he still works very ha

17、rd.虽然他很老，但仍然努力地工作。Though the sore be healed, yet a scar may remain.伤口虽愈合，但伤疤留下了。（谚语）6. 引导条件状语从句的连词要点： 表示状语从句由连词if, unless （=if not） 引导。6.1 f it doesn t rain tomorrow, we will go hiking.如果明天不下雨, 我们就去远足.2.You will get good grades if you study hard.如果你努力学习,就会取得好成绩.3.I will go to the party unless he goe

18、s there too.我不会去参加聚会的, 除非他也去.（如果他不去,我也不去.）难点提示：用条件状语从句时要注意时态的正确使用,当主句是将来时的时候,从句要用一般现在时.7引导地点状语从句的连词（1）地点状语从何由 where, wherever,引导，如：We must camp where we can get water.我们必须在能找到水的地方露营。（ 2）地点状语从句与定语从句的区别where引导定语从何时，从旬前应有一个表示地点的名词作先行词；而状语从何前则无需先行词。如：Go back where you came from.（whe|导地点X犬语从句 ）你从何处来到何处去。
