Unit3《Same or Different》语法过关
形容词副词的原级、比较级
一、同级间比较
1、定义：两者或两部分之间进行比较，没有特征上的差异。
2、句型结构：
①A和B一样…。A + 谓语动词 + as + 形容词 / 副词原级 + as + B．
例如：(1) Sam的英语和Tom的英语一样好。
Sam is as _________ __________ English __________ Tom．
(2) Tara唱得和Tina一样好。
Tara __________ ___________ ___________ __________ Tina．
②A不如B…。A + 谓语动词否定形式 + as / so + 形容词 / 副词原级 + as + B．
例如：(1) Meimei的英语说得不如Feifei的好。
Meimei _________ _________ English __________ _________ _________ Feifei．
(2) 我的妈妈不如我的爸爸风趣。
My mother __________ __________ __________ ___________ my father．
〖易错点〗
1． as … as…结构的中间，应该用“形容词 / 副词原级”。
2． 否定句中，首个as可换成 “so”。
〖拓展〗
★ 否定结构，可改成比较级的句型：
1． Nelly唱得不如Lisa好。(Lisa唱得比Nelly更好。)
Nelly __________ sing ___________ ____________ ___________ Lisa．
Lisa ___________ _____________ ____________ Nelly．
2． Carol不如Paul风趣。(Paul比Carol更风趣。)
Carol __________ ___________ ____________ ___________ Paul．
Paul ___________ ____________ ___________ Carol．
二、形容词和副词的比较级
1、定义：两者或两部分人或物之间的比较。
2、变化规则：
① 规则变化
A． 直接加 -er。
B． 以e结尾，直接加 -r。
C． 以“辅音字母 + y”结尾，变y为i，加-er．
D． 重读闭音节，一个元音字母加一个辅音字母结尾，r, w, y结尾除外，双写末尾的辅音字母，加-er。
E． 部分双音节词和多音节词，形容词加-ly变来的副词，在单词前加more。
②不规则变化
| 原级 | 比较级 |
| good/well | better |
| bad/badly/ill | worse |
| many/much | more |
| little | less |
| far | farther(表示距离：“更远”) |
| further(表示程度：“更进一步”) | |
| old | older(新旧或年龄) |
| elder(兄弟姐妹长幼关系) |
3、句型结构：
①A + 谓动 + 比较级 + than + B
例句：This box is bigger than that one．
②在两者之间选择“哪一个更……”时，用句型“Which / Who is +比较级, ．．． or ．．．?”。
例句：Which sweater is cheaper, the red one or the yellow one?
③A + 谓动 + 比较级 + than + the other + 可复
例句：He is taller than the other boys in his class．
④A + 谓动 + 比较级 + than + any other + 可单
例句：Jennifer is taller than any other girl in her class．
⑤Nobody else / No one / Nothing + 谓动 + 比较级
例句: Nothing is more important than health, so we should do more exercise．
⑥比较级与of the two/of the twins连用时，比较级前加the
例句：Lucy is the taller of the two．
⑦ “the + 比较级，the + 比较级” “越……，越……”
例句：The more you eat, the fatter you will become． 你吃的越多就会越胖。
⑧比较级 + and + 比较级 “越来越……”
多音节词和部分双音节词用“more and more + 形容词原级”。
例句：We should make our country more and more beautiful．
⑨形容词比较级前可以用下列词修饰：much, a little, far, a bit, a lot, even, far等。
例句：It’s much colder today than yesterday．
【拓展】名言中的比较级
