Unit 7知识点总结
一、形容词和副词的原级就是原形.
1. very / so / too / quite +原级（副词修饰形容词，副词）
She is very beautiful. He works quite hard.
[烦恼四] 表示“…是两者中更…的一个”时, 用 “the + 比较级+ of the two”结构。the 不可缺。
使用形容词比较级时需注意以下几点：
1) than后面接代词时, 一般要用主格形式， 但在口语中也可使用宾格形式。 如：My brother is the students.
2. Which / Who is + the 最高级，A, B or C…？ 比较A、B、C三事物, 问其中哪一个最…… 1) Who is the tallest, Lucy，Mary or Kate? 2) Which one is the most popular among students, going to concerts ， going to movies or playing 2.A+be +as +原级 +as+ B. taller than I / me.
3.A+be not+as/so+原级 +as+B.
2) 当需要表示一方超过另一方的程度时，可以用 Lucy is _________Lily. lucy和lily一样高。 much, a lot, a little, a bit, even, still Tom isn’t _______________Jim. Lucy没有lily等来修饰形容词比较级。注意: 比较级不能用高。
very, so, too, quite等修饰。如：He is much more 二. 形容词和副词的比较级
serious than Sam.
（一）主要用于两者比较。表示较……或更……一3) 上下文明确的情况下,形容词比较级可单独，使些的意思。
用不用连词than 。如：
常用far, even，much，a lot, a bit, a little My sister is tall, but my aunt is taller. 等修饰。
4) .“比较级＋and＋比较级”意为“越来（三）形容词和副词的比较级的用法：
越……” 。多音节比较级用“more and more＋1.主语+谓语动词+adj./adv. +比较级+ than+ 对比形容词原级”如：It’s getting worse and 成分
worse.
即：A +（be;实义动词）+比较级+than +B
The group became more and more popular. 2.比较级+and+比较级 或 more and more+原级 5). “Which / Who is + 比较级， A or B？”比3. the +比较级，the+比较级
较A、B两事物, 问其中哪一个较……时用此句型。4.比较级+than any (other)+单数名词 如：
表示同一事物在某一范围内进行比较
Which T-shirt is nicer, this one or that one? 5. the + 比较级+ of the two…是两者中更…的一 Who is more active, Mary or Kate?
6. Which / Who is + 比较级， A or B ? Which one is more popular among students, going 比较A、B两事物, 问其中“哪一个较……” to concerts or going to movies? 1. His computer is cheaper than I. （×） 三．形容词和副词的最高级
2. Mary is very younger than her brother. （×） 一）主要用于三者或三者以上进 行比较表示：某人3. Shanghai is bigger than any city in China. 或某物在某范围内最……的意思。 （×）
（二）结构：
4. Tom is taller of the two brothers. （×） 1. 主语+be/行为动词+the 最高级[烦恼一] 同类事物才能比较
+in(of/among)…
[烦恼二] 错用修饰语。修饰比较级只能用much /
1) in表示环境范围，of /among 表示对象范围 even / far / a little.不能用very / so 2) 形容词最高级前有物主代词时，不加the / too / quite来修饰。
3) 副词最高级前the也可以省掉。 [烦恼三] 同一事物不能比较。同一事物在某一范围
1）He is the tallest in his class. 内进行比较，常用结构比较级+than any 2) He is the tallest of (all)the /the three boys (other)+单数名词
3) He studies the hardest among them /of all
computer games?
3. one of +the +最高级+名词复数 4. the +序数词+最高级+名词
5.“比较级+than any other+单数名词”结构表示最高级概念
6.最高级前的修饰语也可以是first, second, third……
Huanghe is the second longest river in China. 注意以下表达式的含义：the same…as(和……一样)， had better(最好)，less than(不到)，more or less(或多或少)，rather than(而不是)，the more…the more/less(越……就越……) sooner or later(迟早)
最后：一定要判断来用形容词的比较等级，还是副词的比较等级。副词主要用来修饰行为动词的，经常跟在行为动词之后修饰。而形容词主要在系动词之后，名词之前修饰。（难点）
Tom does his homework more carefully than Lily. Tom is more careful than Lily.
