形容词比较级课件
一、内容标准
了解形容词和副词比较级的用法。学会用比较级对自己与他人进行描述,作出比较并进行判断。并能够发表自己的看法。
二、教学目标
1.情感、态度、价值观目标:结合我校的礼和内容以及礼和目标,在教学中通过用比较级进行比对,让学生了解相互的差异,用发展、比较的眼光看待事物,成长成为具有礼和气质和旺盛精气神的时代人才。
2、过程与方法目标:学生以U型小组为单位在合作探究中,让学生了解比较在生活中的比较应用,培养健康、阳光、向上、睿智的礼和气质。
3.知识与能力目标:能在交际中准确地运用比较级对自己与他人进行描述,作出比较并进行判断
三、教学内容分析
本课时中心话题围绕Talk about personal traits and compare people这个题材开展多种教学活动,本节课是本单元的重点,通过听、说、读、写来培养学生综合运用知识的能力,通过有限的课堂实践活动,能准确地用英语在交际中运用本单元的话题对自己与他人进行描述,作出比较并进行判断。并让学生能在“做中学。”通过听、说、读、写来学习比较等级,加深对比较等级的语法现象的理解和运用,培养学生综合运用知识的能力能初步运用这一语言结构进交谈。基于上述对教材的分析,我确定本单元的教学重点为词汇、形容词比较级的构成、形容词比较级的用法。教学难点为the comparatives with–er/ier and more的结构及读音,能在交际中准确地运用本单元的话题对自己与他人进行描述,作出比较并进行判断
四、学情分析
我们教学的对象是初二学生,他们学习英语有较强的`记忆力和模仿能力,有待培养知识的扩展运用能力。有较强的求知欲和表现欲,但部分学生存在不自信,羞于表现等思想顾虑,但又希望能得到他人的肯定。因此我在教学活动中尽量让他们参与到活动中来,有更多的机会来说英语,减少他们的恐惧感,缺少丰富的语言基础,对某些任务的完成有一定的难度,通过学生间的合作学习,降低他们的学习难度,使他们体验到成功的喜悦。同时在阅读和书面表达中加以落实,提高他们综合运用语言的能力,使各层次的学生都有所收获。
五、教学重点及难点
Important points:1形容词比较级的用法
Is that Sam? No, that’s Tom. He has shorter hair than Sam.He’s calmer than Sam.
主语(sb / sth)+ be +形容词比较级+ than +…
Difficult points;形容词比较级的构成:the comparatives with–er/ier and more
六、教学过程
(一)创设情境导入新课
用简单易学的英语歌曲,调动起全班学生的学习热情。这部分的设计采用的是兴趣型的教学策略。旨在上课初吸引同学们的注意力,提起他们的学习兴趣。“良好的开端是成功的一半”,因此,我认为能以一种新颖的问候方式或复习方式进入一节课,就能唤起学生的兴趣,使学生保持一种积极的学习状态,或循序渐进地导入所学的内容,那么可为这节课的成功打下基础,同时也能给自己适当的减压。播放背景音乐《致爱丽丝》

(二)合作探究
目标一 :presentation
任务 :利用多媒体逐步出现6组图,分别是引导学生说出新单词。
本课利用多媒体教学手段展示了一幅幅色彩逼真、形象生动的画面,比较等级在一系列既关联又相对独立的语境中详细讲解,反复演练,使学生全面掌握,充分地调动了学生的积极性,吸引了全体学生的注意力,达到了教育教学目的,培养学生思想素质、情感素质和英语语言素质。
设计目的:学生是任务的主体,让学生通过课前任务自主学习新单词,让学生做一个发现者,研究者,探索者。同时单词融入句型来学习,培养学生在语境中理解、识记单词)
目标二:practice
任务一
SectionA是基本的语言部分,打好本单元目标语言的基础运用听力(1a,2a,2b)pairwork (1c,2c)role---playing(3a)等口语练习活动,充分培养学生学习目标英语的语感。
设计思路:这部分我们采用了任务型的教学策略,在学生进行了反复的操练后,让他们思考形容词比较级的构成、形容词比较级的用法,并做出了归纳(比较级规则变化口诀)
比较级,要变化,一般词尾加er。(long-longer)
词尾若有哑音e,直接加r就可以。(nice-nicer)
重读闭音节, 单辅音字母要双写。(hot-hotter)
辅音字母若加y,记得把y变为i。(happy-happier)
锻炼了学生的思考能力,在接受任务,完成任务的过程中,获得成就感,对句型的掌握更为深入,透彻,从而突破了这个重难点
任务二:Make sentences as more as you can according the pictures
出示多幅图片,根据图片说出含有比较级的句子。采取小组竞赛的方式。
设计思路:
反复操练是记忆的一个重要方法,通过练习句型来强化巩固单词,从而能更好地掌握和使用句型。采取比赛的形式,提高学生的学习兴趣和参与意识,适当引入竞争教学,使学生在激烈、快乐的竞争氛围中,巩固了重难点。
任务三:Say something about your past and now.
目标三:归纳总结
以小组形式对本节课的知识用思维导图的形式归纳总结,以小组为单位进行展示、交流。
目标四:二分钟试卷
1.When KFC meets Mcdonald’s

比较级和最高级的用法
在英语中通常用下列方式表示的词:在形容词或副词前加more(如 more natural,more clearly )或加后缀 -er(newer,sooner )。典型的是指形容词或副词所表示的质、量或关系的增加。英语句子中,将比较两个主体的方法叫做“比较句型”。其中,像“A比B更……”的表达方式称为比较级;而“A最……”的表达方式则称为最高级。组成句子的方式是将形容词或副词变化成比较级或最高级的形态。
一、形容词、副词的比较级和最高级的构成规则
1.一般单音节词和少数以-er,-ow结尾的双音节词,比较级在后面加-er,最高级在后面加-est;
(1)单音节词
如:small→smaller→smallest short→shorter→shortest
tall→taller→tallest great→greater→greatest
(2)双音节词
如:clever→cleverer→cleverest narrow→narrower→narrowest
2.以不发音e结尾的单音节词,比较在原级后加-r,最高级在原级后加-st;
如:large→larger→largest nice→nicer→nicest able→abler→ablest
3.在重读闭音节(即:辅音+元音+辅音)中,先双写末尾的辅音字母,比较级加-er,最高级加-est;
如:big→bigger→biggest hot→hotter→hottest fat→fatter→fattest
4.以“辅音字母+y”结尾的双音节词, 把y改为i,比较级加-er,最高级加-est;
如:easy→easier→easiest heavy→heavier→heaviest
busy→busier→busiest happy→happier→happiest
5.其他双音节词和多音节词,比较级在前面加more,最高级在前面加most;
如:beautiful→more beautiful→most beautiful
different→more different→most different
easily→more easily→most easily
注意:(1)形容词最高级前通常必须用定冠词 the,副词最高级前可不用。
例句: The Sahara is the biggest desert in the world.
(2) 形容词most前面没有the,不表示最高级的含义,只表示"非常"。
It is a most important problem.
=It is a very important problem.
6.有少数形容词、副词的比较级和最高级是不规则的,必须熟记。
如:good→better→best well→better→best
bad→worse→worst ill→worse→worst
old→older/elder→oldest/eldest
many/much→more→most little→less→least
far →further/farther→ furthest/farthest
二、形容词、副词的比较级和最高级的用法
1.“A + be +形容词比较级 + than + B” 意思为“A比B更……”。
如:This tree is taller than that one. 这棵树比那棵树高。
注意:
① 在含有连词than的比较级中,前后的比较对象必须是同一范畴,即同类事物之间的比较。
②在比较级前面使用much,表示程度程度“强得多”。
如:A watermelon is much bigger than an apple.
③ very, quite一般只能修饰原级,不能修饰比较级。
2.“比较级 + and + 比较级”或“more and more +原级”表示“越来越……”
如:It becomes warmer and warmer when spring comes.
春天来了,天气变得越来越暖和了。
It is getting cooler and cooler.
天气越来越凉爽。
The wind became more and more heavily.
风变得越来越大。
Our school is becoming more and more beautiful.
我们的学校变得越来越美丽。
3.在含有or的选择疑问句中,如果有两者供选择,前面的形容词要用比较级形式。
如:Who is taller,Tim or Tom? 谁更高,Tim还是Tom?
4. “the +比较级……, the+比较级”,表示“越……越……”。
The more money you make, the more you spend.
钱你赚得越多,花得越多。
The sooner,the better.
越快越好。
5. 表示倍数的比较级用法:
①. A is …times the size /height/length/width of B.
如:The new building is three times the height of the old one.
这座新楼比那座旧楼高三倍。(新楼是旧楼的四倍高)
②. A is …times as big /high/long/wide/large as B.
如:Asia is four times as large as Europe.
亚洲是欧洲的四倍大。(亚洲比欧洲大三倍)
③. A is …times larger /higher/longer/wider than B.
如:Our school is twice bigger than yours.
我们学校比你们学校大两倍。
6.形容词、副词的最高级形式主要用来表示三者或三者以上人或事物的比较,表示“最……”的意思。
句子中有表示范围的词或短语。如:of the three, in our class等等。
如:He is the tallest in our class.
他在我们班里是最高的。
7."否定词语+比较级","否定词语+ so… as"结构表示最高级含义。
Nothing is so easy as this.
=Nothing is easier than this.
=This is the easiest thing.

②. 还可以用表示倍数的词或度量名词作修饰语。

2)下列词可修饰最高级:by far, far, much, mostly, almost。

8.要避免重复使用比较级。
(错) He is more cleverer than his brother.

(对) He is cleverer than his brother.

10.要注意对应句型,遵循前后一致的原则。

2)The experiment was____ easier than we had expected.

A. the happiest time B. a more happier time
C. much happiest time D. a much happier time
答案:D。
比较级和最高级的用法
1.两者相比(甲=乙),用“as+原级+as”表示

2.两者相比(甲〈 乙),用“not as(so) +原级+as”或“less than”表示

The picture is less attractive than that one.
3.两者相比(甲〉乙),用“比较级+than”表示

注意:1) 为了避免重复,在从句中常用one, that, those等词来代替前面提过的名词。
The weather here is warmer than that of Shanghai.
The radios made in our factory are better than those in your factory.
2)比较等级应注意避免和包括自己的对象比。
比较级+than+
any other + 单数名词
all the other + 复数名词
anyone else
any of the other + 复数名词
3)如果形容词作定语修饰一个单数可数名词,一般将不定冠词a/an放在形容词之后。
Our neighbour has _____ ours.
A. as a big house as
B. as big a house as
C. the same big house as
D. house the same big as
4)比较级前一般不用冠词,但若表示“两者中较……时”。比较级前要加定冠词。若比较级后有名词,常在比较级前加不定冠词,表示泛指。
E.g. 他是两者中较高的一个
He is the taller of the two.
她唱得真动听!我可从未听过比这更好的嗓音了。
How beautifully she sings! I have never heard a better voice.

Zhang Hua is the tallest of the three.
He works (the) hardest in his class.
That was the least exciting football game I’ve ever watched.
This hotel is the most comfortable I’ve ever stayed.
注意:当最高级的前面无限定词the或有不定冠词a/an时,仅表示“很……,非常……”
Monday is my busiest day.
星期一是我很忙的一天。
Qingdao is a most (very) beautiful coastal city.
青岛是一个非常美丽的海滨城市。

【答案与解析】
1. C。根据题意可知,说话者是将when people do it together和when people don’t do it together这两种情况比较,故选比较级。注意不要选D,因为在此题是要用副词修饰动词,不能用形容词。另外,根据句末的higher too也可知道此题是考查比较级。
2. D。首先,根据连系动词后要接形容词作表语这一特点,可排除A和C。另外,使役动词make后可接动词原形(不带to的不定式)或过去分词作宾语补足语,但不能接现在分词,故可排除选项B。
3. D。take sth seriously的意思是“认真对待某事”“认真考虑某事”。
4. C。副词narrowly在此表示“勉强地”,又如:He narrowly escaped being run over. 他差点儿被车压死。 The proposal to change the rules was narrowly defeated by 201 votes to 196. 建议改变规则的提议以196票对201票的微弱差额被否决了。本题句意:篮球赛的最后比分是93比94。我们以微弱的劣势输掉了比赛。
5. B。因题目把这组新学生与前面一组学生进行比较,故用比较级。
6. B。注意句中的Yes,由于答话者对问话者的“你需要帮助吗?”作了肯定回答,说明答话者独自完成工作有困难,故填more than。
7. C。由于是将“Love me, love my dog”与“Love me, love my book”进行比较,故用比较级。此题的`巧妙之处在于句中没有出现than,而是给出两个待比较的proverb。
8. B。句子大意为:由于铁路提速了,所以高速公路和航空业要提高服务质量来竞争客源。因将“高速公路和航空”与“铁路”比较,故用比较级。
9. B。题目中将“放入冰箱中冷冻”与“不放入冰箱中冷冻”作比较,故用比较级。句意为:史密斯家人晚餐时上的甜瓜若能放入冰箱中冷冻一下味道会更好些。
10. B。这四个副词中,通常只有far可用于修饰比较。注:quite有时也可用于修饰比较better,但它只用于表示“身体康复”,不用于其他意义。
11. C。因为是从他所写的所有歌中选出一首来比较,故用最高级。
12. B。因是两者比较,故用比较级,可将答案锁定在B和C之间;再根据句意,排除C。
13. D。此题考查more?than?的用法,其意为“与其说??不如说??”。
14. D。句中的no better than相当于as badly as,其意为“一样不好”。
15. A。that在用作副词,用法相当于so,意为“如此,这么”。
16. C。在as?as?结构中,表示倍数的词或程度副词都放在第一个as之前。
17. A。语序:不定代词 + 指示代词 + 序数词 + 基数词。
18. A。此题考查can’t be too + adj,其意为“无论??也不为过”。
19. A。因为likely是形容词,意为“可能的”,在句中作表语。easily和nearly是副词;虽然lonely(寂寞的)
是形容词,但其意义与句意不通。
20. C。因为只有regularly(经常地)才与now and then(偶尔)相对。
21. C。merely在此表示“只是”,其他选项意义不通。
22. A。因为It couldn’t be any worse. 意为“(他的工作做得)非常差”,与后文内容相符。
23. A。因为too?to do sth. (太?以至于不能做?) 是固定搭配。
24. A。由答语No, it’s worse.可知问句中用better。
25. B。后面省略了than he did,意为“我今年还没看到比他跑得更好成绩的人”。
