(一). 三级变化.

(A). 规则变化

1. 单音节和少数双音节形容词(多半是没加前缀或后缀的形容词)的规则变化. (1). 一般在形容词词尾直接加er构成比较级, 直接加est构成最高级 如:

tall→taller→tallest long→longer→longest, short→shortest

(2) . 以不发音的字母e结尾的形容词 只需加r构成比较级, 加st构成最

高级。如: nice→nicer→nicest, fine→finer→finest, large→larger→largest (3). 以辅—元—辅结尾的重读闭音节形容词 先双写这个辅音字母 再加

er构成比较级 加est构成最高级 如

big→bigger→biggest hot→hotter→hottest, red→redder→reddest

(4). 以辅音字母+y结尾的形容词 先把y变为i 再加er构成比较级, 加

est构成最高级 如: busy→buier→busiest, easy→easier→easiest.

2. 部分双音节形容词(多半是加了前缀或后缀的形容词)和多音节形容词在原级前加more构成比较级, 在原级前加most构成最高级 如:

tiring→more tiring→most tiring, relaxing→more relaxing→most relaxing,

※1. old 有两种比较级和最高级形式: older/oldest 和elder/eldest. 其中elder, eldest只用于兄弟姐妹的大小关系, 且不能用于含有than的句子中.

My elder brother is an engineer. Mary is the eldest of three sisters.

2. far 有两种比较级 farther/further. 在英国英语中两者都可指距离. 但在美国英语中 father 表示距离 further表示“进一步的”.

I have nothing further to say. futther study.

(二) 三级标志

1 句子使用原级的两大标志

a. 当句中含有as (so)…as…时句子一般使用原级. (肯定句中只能用as, 而否定句中可用so或as)

Tom is as old as Kate. Tom is twice as old as Kate.

His English is as good as yours. This room is not as/so big as that one.

b. 当形容词前含有quite, so, too, very等副词时句子一般用原级

2.句子使用比较级的三大标志

当句中含有than一词时, 句子一般使用比较级, 构成形式为: “形容词比较级+than…. ”, 意为:“比…更加……”.

He is taller than his brother.

There are more students in Class One than in Class Two.

b. 当句中含有…. A or B? 时句子一般使用比较级。

Which is better, the red one or the green one?

c. 当句中含有of the two (+n) 时 句子一般使用比较级。

The Yangtze River is longer than any other river in China.

b. 当句中含有表示范围的介词of …时句子一般使用最高级。

He is the tallest of the three.

c. 当句中含有one of the……时句子一般使用最高级。one of the + 形容词最高级+ 复数名词, 表示"最……的……之一"。

The Yellow River is one of the longest rivers in China.

d. 当句中含有…, A B or C ? 时 句子一般使用最高级。

初中英语语法——动词的时态

动词的时态 一、考点解读 今天我们复习动词的时态,英语的时态是同学们学习英语的难点,在各地的中考题目中许多题型都会有对于动词时态的考查。出现较多的是在单选,完形填空,及其在第二卷中出现的根据汉语意思填词的题目,还包括翻译句子,书面表达。可以说中考题目中大部分都会涉及到动词的时态。既是难点也是重点。在今天的专题中我们复习初中阶段需要掌握的八个时态。 1.一般现在时 2.现在进行时 3.一般过去时 4.过去进行时 5.一般将来时 6.过去将来时 7.现在完成时 8.过去完成时 二、专题梳理 初中阶段所学的英语的时态有8种。英语的时态有很强的表达能力,能使句子的意思明确,能显示细微的差异,能使句子生动逼真。但它们不是相当灵活,在不同的时间中,要用不同的形式,这是与中文大不相同的地方。 1.一般现在时:一般现在时是描述经常性、反复性的动作、性质或状态的时态。 (1)一般现在时的时间状语通常有: ①often ②usually ③always

④seldom ⑤sometimes ⑥every+时间 ⑦次数+时间 ⑧on+时间 ⑨in+时间 ⑩没有时间,但表示客观存在的事实 (2)一般现在时动词的形式主要用动词原形表示,但如果主语是单数第三人称时,则在动词后加s或es,变成否定句和疑问句时,又将s、es去掉,还为原形。 ①be动词的一般现在时的构成 否定式和疑问否定式如下表所示: ②其他实义动词的一般现在时的构成

其他实义动词一般现在时的构成如下 表所示(以动词work为例) 特别提示: have(has)在表示“有”时,否定形式为haven’t(hasn’t)或have not(has not),变为疑问句时可直接把have(has)放在句首也可借助于助动词do(does)。当不表示“有”的意思时,其否定句和疑问句只能加助动词do(does)构成。 e.g.Has she any experience in teaching piano lessons?(√) Does she have any experience in teaching piano lessons?(√) 她有教钢琴的经验吗? Had you a good time going hiking yesterday?(×) Did you have a good time going hiking yesterday?(√) 你昨天徒步旅行玩得开心吗?

初中英语语法形容词、副词精华版

初中英语语法形容词、副词的复习教案 Brainstorm: 你能分清形容词和副词的用法和写法吗?你知道怎么使用形容词和副词的比较级和最高级吗?你知道在英语中有很多形容词词缀吗? 一.形容词和副词的辨析 1.形容词和副词的区别 形容词:用来修饰名词 副词:用来修饰动词、形容词和副词 所以区别形容词和副词的关键在于看它所修饰的内容。 例如:Candy is a lovely girl. Candy smiles lovely. 在这两句话中,都有lovely这个单词,但是词性却完全不同。在第一句中lovely用 来修饰girl所以是形容词,而第二句中,lovely用来修饰动词smiles,所以是副词。 2.形容词变副词的规律 a.一般的形容词在结尾加ly变为副词。例如:careful-carefully b.以元音加e结尾的单词要去e在加ly。例如:true-truly c.辅音加y结尾的单词去y变i在加ly。例如:angry-angrily d.单音节y结尾直接加ly。例如:shy-shyly e.以le结尾的单词直接将e变为y。例如:terrible-terribly f.形容词、副词同形:hard, fast, friendly, late, early, lovely, long。这部分请同学们 注意,其中很多单词加ly之后就变成其他意思的单词了。例如:hardly就变成 “几乎不”的意思,是小学阶段五大隐形否定词(few,little, never, seldom, hardly) 之一。 二.形容词和副词的比较级 1.比较级的范围:一般为两者或两个部分进行比较。例如:I’m taller than you. Group One did better than Group Two. 2.比较级的结构:结构上比较级有三个明显的标志。 ①than:一般用than连接两个比较的部分。例如:Tom runs faster than Mike.其中Tom 和Mike是比较的两部分,用than连接他们进行比较。在than的句式中有一个需要 同学们特别注意:I’m taller than any other students in my class.这句话中用than连接 的是I和any other students in my class两个部分,其实表示的是最高级的概念,译 为我比我们班其他同学都要高,其中any other ……是固定搭配,译为任何其他的。 ②a little, much, a lot, even, still:可用来专门修饰比较级。例如:Lisa was sick yesterday, while today she is much better. ③as+形容词或副词原形+as……:译为像……一样。例如:Mary is as clever as Susan.Mary像Susan一样聪明。 另外,两个比较级连用表示“越来越”的意思。例如:Days get longer and longer in Spring.白天在春天越来越长了。 3.比较级的写法: ①单音节单词后+er。例如:tall-taller, short-shorter ②重读闭音节双写最后一个字母再加er:hot-hotter, big-bigger, thin-thinner, fat-fatter ③双音节辅音+y结尾去y变i再加er:ugly-uglier, busy-busier, easy-easier, early-earlier,

初中英语语法总结--形容词

初中英语语法总结--形容词 1、形容词及其用法 形容词修饰名词,说明事物或人的性质或特征。通常,可将形容词分成性质形容词和叙述形容词两类,其位置不一定都放在名词前面。 1)直接说明事物的性质或特征的形容词是性质形容词,它有级的变化,可以用程度副词修饰,在句中可作定语、表语和补语。例如:hot热的。 2)叙述形容词只能作表语,所以又称为表语形容词。这类形容词没有级的变化,也不可用程度副词修饰。大多数以a开头的形容词都属于这一类。例如:afraid害怕的。 (错)He is an ill man. (对)The man is ill. (错)She is an afraid girl. (对)The girl is afraid. 这类词还有:well,unwell,ill,faint,afraid,alike,alive,alone,asleep,awake等。 3)形容词作定语修饰名词时,要放在名词的前边。但是如果形容词修饰以-thing为字尾的词语时,要放在这些词之后,例如: something nice 2.以-ly结尾的形容词 1)大部分形容词加-ly可构成副词。但friendly,deadly,lovely,lonely,likely,lively,ugly,brotherly,仍为形容词。 改错:(错) She sang lovely. (错) He spoke to me very friendly.

(对) Her singing was lovely. (对) He spoke to me in a very friendly way. 2)有些以-ly结尾既为形容词,也为副词。 daily,weekly,monthly,yearly,early The Times is a daily paper.
