日期表达
英语日期的表达与汉语不同。英语表达的顺序为
"月、日、年",2004年11月4日就可写成November 4th, 2004,还可表示为
November fourth, 2004。也可写成"日、月、年",4th November, 2004即the fourth of November, 2004。
朗读方面在朗读时,"月份"一般直接用英语读出;"日"则要读成"the 序数词";
读年份时,一般分为两个单位来读,前两个数为一个单位,后两个数为一个单位。
如:1982年读作nineteen eighty-two, 1900年读作nineteen hundred。
如果是三位数,先读第一位,再把后两个数合起来读。
如:984年可读为nine eighty-four,757年读成seven fifty-seven。
另外,像2000年一般读成two thousand, 2001年则读成two thousand and one,
以此类推,2004年应读成two thousand and four。
January 12th, 1993读成January the twelfth, nineteen ninety-three。

英语日期的表示法
用英语表示日期,其顺序为“月+日+年”,日和年之间需用逗号隔开。
如:August 2nd,2003(2003年8月2日)。
也可以用“日+月+年”来表示。如:10th May,2003(2003年5月10日

英语日期前介词的使用:若指在哪一年或哪一月,则用介词in,若具体到
某一天,则需用介词on
January一月(略写为Jan.) February二月(略写为Feb.) March三月
(略写为Mar.) April 四月(略写为Apr.) May五月
June 六月 (略写为Jun.) July七月 (略写为Jul.) August八月 (略写为
Aug.) September九月(略写为Sept.) October十月(略写为Oct.) November十一月

Ⅵ 八年级英语需要掌握的语法有那些

一、词法

1、名词

A)、名词的数

我们知道名词可以分为可数名词和不可数名词,而不可数名词它没有复数形式,但可数名词却有单数和复数之分,复数的构成如下:

一)在后面加s。如:fathers, books, Americans, Germans, apples, bananas

二)x, sh, ch, s, tch后加es。如:boxes, glasses, dresses, watches, wishes, faxes

三)1)以辅音字母加y结尾的变y为i再加es 如:baby-babies, family-families, ty-ties, comedy-comedies, documentary-documentaries, story-stories

2)以元音字母加y结尾的直接加s。如:day-days, boy-boys, toy-toys, key-keys, ways

四)以o结尾加s(外来词)。如:radios, photos, 但如是辅音加o的加es:如: tomatoes西红柿, potatoes马铃薯

五)以f或fe结尾的变f为v再加es(s)。如:knife-knives, wife-wives, half-halves, shelf-shelves, leaf-leaves, yourself-yourselves

六)单复数相同(不变的)有:fish, sheep, deer鹿子, Chinese, Japanese

七)一般只有复数,没有单数的有:people,pants, shorts, shoes, glasses, gloves, clothes, socks

八)单词形式不变,既可以是单数也可以是复数的有:police警察局,警察, class班,同学, family家,家庭成员

九)合成的复数一般只加主要名词,多数为后一个单词。如:action movie-action movies, pen pal-pen pals; 但如果是由man或woman所组成的合成词的复数则同时为复数。如:man doctor-men doctors, woman teacher-women teachers

十)有的单复数意思不同。如:fish鱼 fishes鱼的种类, paper纸 papers报纸,卷子,论文, work工作 works作品,工厂, glass玻璃 glasses玻璃杯,眼镜, orange桔子水 oranges橙子, light光线 lights灯, people人 peoples民族, time时间 times时代, 次数, chicken 鸡肉 chickens 小鸡

十一) 单个字母的复数可以有两种形式直接加s或’s。如:Is (I’s), Ks (K’s)。但如是缩略词则只加s。如:IDs, VCDs, SARs

十二) 特殊形式的有:child-children, man-men, woman-women, foot-feet, mouse-mice, policeman-policemen, Englishman-Englishmen

B)名词的格

当我们要表示某人的什么东西或人时,我们就要使用所有格形式。构成如下:

一)单数在后面加’s。如:brother’s, Mike’s, teacher’s

二)复数以s结尾的直接在s后加’,如果不是以s结尾的与单数一样处理。如:Teachers’ Day教师节, classmates’; Children’s Day六一节, Women’s Day三八节

三)由and并列的名词所有时,如果是共同所有同一人或物时,只加最后一个’s,但分别拥有时却分别按单数形式处理。如:Mike and Ben’s room迈克和本的房间(共住一间),Mike’s and Ben’s rooms迈克和本的房间(各自的房间)

2、代词

he him his his himself
it it its its this that itself
复数 they them their theirs these those themselves

3、动词

A) 第三人称单数

当动词是第三人称单数时,动词应该像名词的单数变动词那样加s,如下:

一)一般在词后加s。如:comes, spells, waits, talks, sees, dances, trains

二)在x, sh, ch, s, tch后加es。如:watches, washes, wishes, finishes

三)1)以辅音字母加y结尾的变y为i再加es。如:study-studies, hurry-hurries, try-tries

四)以o结尾加es。如:does, goes

五)特殊的有:are-is, have-has

B) 现在分词

当我们说某人正在做什么事时,动词要使用分词形式,不能用原形,构成如下:

一)一般在后加ing。如:spell-spelling, sing-singing, see-seeing, train-training, play-playing, hurry-hurrying, watch-watching, go-going, do-doing

二)以不发音e的结尾的去掉e再加ing。如:dance-dancing, wake-waking, take-taking, practice-practicing, write-writing, have-having

三)以重读闭音节结尾且一个元音字母+一个辅音字母(注意除开字母组合如show –showing, draw-drawing)要双写最后的辅音字母再加ing。如:put-putting, run-running, get-getting, let-letting, begin-beginning

四)以ie结尾的变ie为y再加ing。如:tie-tying系 die-dying死 lie-lying 位于

4、形容词的级

我们在对两个或以上的人或物进行对比时,则要使用比较或最高级形式。构成如下:

一) 一般在词后加er或est(如果是以e结尾则直接加r或st)。如:greater-greatest, shorter –shortest, taller –tallest, longer –longest, nicer- nicest, larger -largest

二)以重读闭音节结尾且1个元音字母+1个辅音字母(字母组合除外,如few-fewer fewest)结尾的双写结尾的辅音再加er /est。如:big-bigger biggest, red-redder reddest, hot-hotter hottest

三) 以辅音字母+y结尾的变y为i加er/est。如:happy-happier happiest, sorry-sorrier sorriest, friendly-friendlier friendliest(more friendly most friendly), busy-busier busiest, easy-easier easiest

四)特殊情况:(两好多坏,一少老远)

good/well - better best many/much - more most bad/ill – worse worst

little- less least old- older/elder oldest/eldest far- farther/further farthest/furthest

5、数词 (基变序,有规则;一、二、三,自己背;五、八、九、十二;其它后接th;y结尾,变为i, eth跟上去。) first, second, third; fifth, eighth, ninth, twelfth; seventh, tenth, thirteenth, hundredth; twenty-twentieth, forty-fortieth, ninety-ninetieth

Ⅷ 求八年级英语知识点归纳,详细点的

一、快读查疑。首先浏览课本,遇到较为生疏的、已被遗忘的词语,集中抄在一个本上,以便随时复习,重点记忆。

二、以点带面。以一个单词或语言点为中心,向四周辐射,找出与之相关的词语和用法。比如,学习一个名词,应知道它是可数的还是不可数的;如果是可数名词,其复数形式怎样变化;是不可数名词,又应怎样使用;它有没有动词形式或形容词形式。再如一个动词,其第三人称单数形式、现在分词形式是怎样变化的?应如何使用?有没有固定用法?运用这个方法,可以得到举一反三、事半功倍的良好效果。如纵向方面,每一个单词的读音、拼写和用法如何,某一个语法现象是怎么回事;横向方面,如同音词有I-eye,meat-meet,where-wear等;同义句Could you give me a hand?-Could you help me?;反义词bring-take,in-out,现在进行时与一般现在时的对比等等。

三、归纳比较。将同类的知识点归纳在一起,比较其相同点和不同点。比如,表示“带、拿”的几个词:take, bring, get, carry, 应如何区别运用?in, on, at怎样表达不同的时间?一定要掌握它们的细微差别,并能熟练运用。

英语复习要注意以下几个方面:

1.以课本为主,巩固基础知识。课本是英语学习的基础,也是测试的根据。试卷中大部分考点都来源于课本。

2.不断筛选,稳扎稳打。语言基础知识包含语音、词汇和语法,我们复习时要按照一定的顺序,全面进攻,各点击破,掌握的知识放下,没有掌握的重新学习,直至掌握。

3.以练为主,精学精练。复习时我们可以先结合课本的深度和难度进行有针对性的学习,之后就应马上进行相关的练习,只有在练习中我们才能更容易地发现问题,找出自己没有掌握的知识,然后再进行更加有针对性的学习和练习。这样不断地查漏补缺,我们就会在有限的时间内掌握更多的知识。

4.加强基本技能的训练。基础知识掌握了,可以说考试已经有了很大把握。如果我们对自己的要求再严格一些,那么就会很轻松地获得高分。怎样严格呢?对于课文我们不仅要背诵下来,而且还要默写、改写、复述。课后,我们还要听、读英语材料,掌握相应的技能。

英语复习“要”与“不要”

要熟悉构词法知识。近年的英语试题有一个趋势,就是每年都有不少的"纲外词",有派生词和合成词、加注词(即加注了中文的生词)、纯生词。对这些"纲外词"同学们没有事先准备,只能凭语感和特定语篇中的语境进行猜测,而派生词和合成词则是一些同学似熟非熟的词,要想搞定它们,一个比较好的办法就是借助构词法知识。

要注意语法题的常考考点。英语语法题的常考考点有:名词、不定代词、冠词、形容词和副词的比较等级及用法、时态与语态、情态动词、短语动词、宾语从句、状语从句、定语从句、it用法等。这些考点在具体命题时,往往会涉及一定的语言环境,使之具备一定的情景性。所以同学们在复习时,不能只死背一些语法条条框框,而应注意语法规则在具体语言中的灵活运用。

要注意全面发展。这里说的全面发展,是指英语范围内的全面发展,它包括两个方面的内容:一方面指听、说、读、写"四会"的全面发展,另一方面也指各个题型的全面发展。同学们千万不要凭兴趣只顾及自己喜欢的"一面",而忽略了其他方面。

不要放松听力训练。考前放松听力训练有两种可能:一是有的同学认为自己的听力不行,反正再练也不会有什么提高,所以干脆放弃;二是有的同学认为自己的听力已达到了一定的水平,而自己其他方面还比较薄弱,暂时把听力放下,强化一下其他方面。这两种想法都很危险。经验告诉我们,听力是一种比其他能力(如阅读能力、写作能力等)更容易丧失的能力,不容片刻忽视。

不要死抠教材。读好教材固然重要,但如果只是读好教材,那还是远远不够的,至少阅读量就大大地不够,教材所提供的英美文化背景也很有限。所以同学们除认真读好教材外,还应主动地进行课外阅读,同时要兼顾各种题材和体裁,有意识地扩大自己的知识面,培养语感和提高综合能力。

不要过分追究"所以然"。一般认为,学习不仅要知其然,而且要知其所以然,但英语学习有所不同。英语作为一门语言,在许多情况下都是约定俗成的,从某种意义上说,语感比那种所谓的理由更有价值。

不要用汉语思考英语。用汉语思考英语弊端不少。比如当你做听力题时,用汉语思考,会跟不上录音;当你做阅读题时,用汉语思考,不仅会多用不少时间,而且会不易掌握大意;当你做书面表达题时,用汉语思考,会写出一些违背英语习惯的汉语式的句子(注:书面表达题评分时,视不合英语表达习惯的句子为"大错")。

不要忽视书写。有不少同学平时不注意书写,字迹潦草,这对书面表达题的得分是十分不利的。如果书写不规范,会丢失一些"冤枉"分;同时,按评分标准本身,字迹不工整也要扣除卷面分的。所以,同学们在考前应重视书写练习。一、快读查疑。首先浏览课本,遇到较为生疏的、已被遗忘的词语,集中抄在一个本上,以便随时复习,重点记忆。
