1、语法：形容词、副词原级两者的同级比较用 asas 结构（否定 not as/soas)，表示 “与一样（不如）” ，其间应接形容词原级，不能用比较级。He is as tall as his father.他与他父亲一样高。He is not as/so tall as his father.他不如他父亲高。形容词的比较级和最高级1. 形容词比较级和最高级的构成常用的不规则形容词比较级和最高级变化形式 原级 比较级 最高级good/wellmany/ muchbad/ill/badlyoldfar2. 形容词比较级的定义英语中，表示两者（人或事物）相比较时，要用形容词的比较级。3. 形容词比较
2、级的用法1. 最基本句型“ 主语+be(is, am, are) +形容词比较级+than+比较对象”，than 后接人称代词时可以是主格或者是宾格。Than 前后比较对象必须是同一范畴，即同类事物时间的比较。She is a little more outgoing than me/I. 她性格比我外向点。2. 比较级前可以用 much, a little, a lot, even, rather, still, any, a bit, far 等词修饰，起强调作用。不可用 very, so, quite, too（只能修饰原级）等修饰。Its cold today, but it is g
3、oing to be even colder tomorrow.今天很冷，但是明天会更冷。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。Who do you think is more beautiful, Lucy or Lily?你认为谁更漂亮，露西还是莉莉？4. “get/become+形容词比较级+and+形容词比较级”表示“ 变得越来越.”的意思。It gets warmer and warmer when spring comes. 春天来了，天气变得越来越暖和了。5. “the+形容词比较级，the+形容词比较级.”意为 “越.就越.” 两个比
4、较级不要求一定词性相同，它们各自的词性要依句子的需要而定。The harder you work at your study, the better grades you will have.你学习越努力，你的成绩就越好。6. 表示 “比大（长、多、宽.）几倍”用 “times+形容词比较级+than.”结构。Ours classroom is twice larger than yours. 我们的教室比你们的大两倍。7. 表示 “重几斤，高几厘米，大几岁”等，可用“ 表示数量的词 +形容词比较级+than.”Tom is six years older than you. 汤姆比你大六岁。
5、8. “形容词比较级 +than any other+单数可数名词”表示“.比其他的任何都.”，此句型可以换成最高级。Li Lei is cleverer than any other student in the class.=Li Lei is the cleverest student in the class.李磊是班上最聪明的学生。9. “more+形容词”与“less+形容词”及“not so/as.as”的互换。要注意前后比较对象要倒换位置。Chinese is more important than English.汉语比英语重要。=English is less import
