Revision
Grammar Focus
Tips: 形容词常与be动词连用；
副词修饰行为动词，并往往位于动词后面。
形容词和副词的比较等级
大多数形容词和副词有三个等级：
1. 原级，即原形。e.g. good, fast, outgoing ...
2. 比较级，表示“较......” 或“更......一些”。 e.g. better, faster, more outgoing ...
3. 最高级，表示“最......”。 e.g. best, fastest, most outgoing ...
形容词、副词的比较级的规则变化:
单音节和少数双音节形容词、副词比较级的构成。
1) 在词尾加-er
tall — taller smart—smarter
short — shorter fast —faster
2) 以不发音的字母e 结尾的，加-r
nice — nicer large — larger
fine — finer late — later
3) 重读闭音节结尾且末尾只有一个辅音字母的，先双写该辅音字母，再加-er。
big — bigger fat — fatter
thin — thinner hot — hotter wet— wetter
4) 以辅音字母+y结尾的词，先变y为i，再加-er。
happy—happier early— earlier
funny—funnier easy — easier
5)多音节词和部分双音节词
beautiful — more beautiful
comfortably — more comfortably
quickly — more quickly
比较级构成的不规则变化:
Let’s chant !
比较级有规律, 词尾加上-er两兄弟;
要是以e来结尾, 只有小二(r)跟上去;
重读闭音节词要牢记, 双写千万别忘记;
要是“辅音+y”来结尾, 小艾(i)要把y来替, 再加-er两兄弟;
多音节词加上m-o-r-e, 你看这样多容易。
易混淆辨别
older与elder
My elder sister is three years older than me.
Tom, you need to be polite. They are all our elders (n. 长辈).
易混淆辨别
farther与further
farther表示距离上更远。
e.g. I have to walk farther to work now.
further即可表示距离上更远，也可表示程度上或抽象意义上
的更深远或更进一步。
e.g. Let's consider this point further.
further还可作动词，表示“促进；增进”。
e.g. She took the new job to further her career.
1.A + be + 形容词比较级 + than + B
2.A + 实义动词 + 副词比较级 + than + B
注意：than前后所使用的动词相同时，通常用助动词代替后面的动词或省略后面的动词。
e.g. Tom is taller than me.
e.g. Tom runs faster than me (do).
比较级常用句型
3.“the + 比较级 + of the two” 意为 “两者中比较......的”。
e.g. English is becoming more and more important.
4.“比较级 + and + 比较级” 或 “more and more + 形容词/副词原级”，表示 “越来越……”，其后均不可接than。
5.“The + 比较级, the + 比较级” 意为 “越……，越……”。
e.g. The harder she worked, the more progress she made.
e.g. After the new year, the day is becoming warmer and warmer.
e.g. Lisa is the taller of the two girls.
6.“Which/Who... + 比较级, A or B ” 表示 “A和B，哪一个/谁更……？”
e.g. Who is taller, Jim or Tom
7.“A...+ 倍数 + 比较级 + than + B” 表示 “A是B的多少倍”。
e.g. Our school is three times bigger than yours.
8.“比较级 + than any other + 可数名词单数” = “比较级 + than the other + 可数名词复数”，表示“比其他任何/所有……都……”。该句型在同一范围内进行比较。
e.g. China is larger than any other country/the other countries in Asia.
9.“比较级 + than any + 可数名词单数”，意为 “比任何......都”，表示不在同一范围内比较。
e.g. China is larger than any country in Africa.
10.否定 + 比较级”，意为 “不能更......”或“再......不过了”，表示最高级的意思。
e.g. It couldn’t be better. 那再好不过了。
e.g. I can’t agree more. 我再同意不过了。
可修饰比较级的词
当表示一方超过另一方的“程度”时，可以用much, a lot, a little, a bit, even, far等来修饰形容词比较级。注意：比较级不能用very, so, too等修饰。
e.g. He is much more serious than his brother.
e.g. This book is even more useful than that one.
e.g. Can you come to school a little earlier tomorrow morning
巧学妙记：两多(much, a lot)两少(a little, a bit)一甚至(even)，还有一个远（far）去了。
as ... as 与......一样......
as...as用来进行同级比较，中间要用形容词或副词的原级。
同级比较用原级，as ... as永不离。若是否定加not，后者总是强前者。
as ... as的否定结构是not as / so...as，意为“不如......那样......”。
用原级表示比较级的句型
e.g. This movie is as moving as that one.
e.g. My sister is not as / so outgoing as me.
