1、英语语法知识讲解重难点知识讲解：形容词的比较级和最高级一、比较级的定义：大多数的形容词都有三个级别：原级、比较级、最高级。其中比较级表示“更”，用于两者之间的比较，用来说明“前者比后者更”，比较级前面一般用much, even, a little修饰，其中even, much 只能修饰比较级。二、比较级的构成：（1）规则变化：单音节和部分双音节的形容词一般在词尾加-er Eg: calm-calmer tall-taller smart-smarter以字母e结尾的直接在词尾加-r Eg: nice-nicer fine-finer large-larger以“辅音+y 结尾的词，变y为 i，

2、再加-er” Eg: early-earlier happy-happier busy-busier以重读闭音节的单个辅音字母结尾的词，双写辅音字母，再加-er Eg: big-bigger thin-thinner hot-hotter多音节或部分双音节的形容词在原级前面加more Eg: popular-more popular important-more important different -more different- most different beautiful-more beautiful-most beautiful deliciousmore deliciousmo

3、st delicious（2）不规则变化：少数形容词的比较级变化是不规则的： Well/Good betterbest bad /illworseworst many /much moremost little /few lessleast far fartherfarthest /furtherfurthest 三、比较级的用法:(一)当两个人或事物（A和B）进行比较时，我们需要用到形容词（副词）的原级或者比较级1 表达“A和B一样”，用asas的结构。公式: A+be动词+as+形容词原级+as+B A+实义动词+as+副词原级+as+BEg I am as tall as you.我和你

4、一样高。 He runs as fast as I. 他跑得和我一样快。2表达“A不如B”用not asas的结构。公式: A+be动词的否定形式+as+形容词原级+as+B A+助词的否定形式+动词+as+形容词原级+as+BEg I am not as tall as you.我没有你高。 He doesnt run as fast as I. 他没有我跑得快。2 表达“A大于B”用“比较级+than”的结构。公式: A+be动词+形容词比较级+than+B A+实义动词+副词比较级+than+BEg I am taller than you.我比你高。 He runs faster th

5、an I. 他跑得比我快。(二)关于形容词、副词比较级的更多用法1比较级前面可以加上表示“优劣程度”的词或短语，意思是“更”，“得”。常见词有much, a little, even, a lot, a great deal等。Eg He is much taller than I.他比我要高得多。 I jump a little higher than he.我跳得比他高一点点。2.比较级前面可以加上表示具体数量差别的结构,表示具体“大多少”，“小多少”，“长多少”，“短多少”等。Eg I am two years older than he.我比他大两岁。This building is

6、20 meters higher than that one.3“比较级+and+比较级”表示“越来越”。 It is getting warmer and warmer天气越来越暖和。He is running faster and faster他跑得越来越快。0ur country is becoming more and more beautiful我们祖国越来越美了。4“the more， the more”表示“越，就越”，The more，the better.多多益善。The more careful you are, the fewer mistakes you will ma

7、ke.你越细心，犯错就越少。5“the moreof the two”表示“两个当中较。的一个” The taller of the two boys is my brother6.表示“几倍于”的比较级：用twice (两倍)，four times (四倍)，ten times (十倍)加上as as 结构 This one is four times as big as that one. 这个是那个的四倍大。(这个比那个大三倍。) / Our campus is three times as large as yours. 我们的校园比你们的大两倍。 / He has books twi

8、ce as many as she does. 他的书比她多一倍。 7.“the same 名词as”表示同等比较 8.比较级前可用a little, a bit, slightly, a great deal, a lot,many, much等词语表示不定量，far, completely,still表示程度或更进一步四、最高级 三者或者三者以上的人或物进行比较时，需要使用形容词的最高级。其结构是： A + + the 形容词最高级 + of / in + 比较范围.(Note: 形容词最高级前面要加 定冠词 the)e.g. Jackei is the tallest in our cl

9、ass. or Jackei is the tallest of all the students.五、当三个或三个以上的人或事物进行比较时，我们需要用到形容词（副词）的最高级1表达“是中最的”,用“the+形容词（副词）的最高级”的结构。后面可以加上表示范围的介词短语或从句。公式：主语+be动词+the +形容词最高级+（名词）+表示范围的介词短语或从句主语+实义动词+（the） +形容词最高级+表示范围的介词短语或从句Eg He is the tallest (student) in our class.
