5. 双重所有格：
如果被修饰的名词前有不定冠词、不定代词、指示代词、疑问代词修饰。则要采用双重所有格。
a friend of mine（名词性物主代词）
a child of hers
the love poems of your sister’s
注意区别：
● a portrait of her mother 她母亲的画像（画中人）
● a portrait of her mother’s 她母亲拥有的画像中的一幅（不一定是她母亲的画像）
第三章 形容词、副词比较级和最高级
Comparative degree & Superlative degree
比较级构成方式：
A. adj/adv + er/est
poor → poorer → poorest fast → faster → fastest
B. 词尾e + r/st
large → larger → largest fine → finer → finest
C. 重读闭音节中短元音 + 辅音词尾 → 双写辅音词尾 + er/est。
big → bigger → biggest hot → hotter → hottest
D. 辅音 + y → I + er/est
dry → drier → driest angry → angrier → angriest
E. 多音节形容词及副词：
more + adj/adv most + adj/adv
F. 不规则变化：
good/well → better → best bad/ill → worse → worst
many/much → more → most little → less → least
late → later → latest
late → latter → last
far → farther → farthest
far → further → furthest
【用法示例】：
比较级用于二者相比较，由than构成比较状语从句：
(1)
Ø. He looks stronger than I (do).
Ø. The climate of Shanghai is hotter than that of Beijing.
Ø. My Schoolbag is larger than hers.
Ø. The book is much more interesting than that one.
(2)
Ø. It is getting colder and colder.
Ø. She is becoming more and more beautiful.
笔记要点：两个形容词比较级由and 连在一起，表示“越来越……”
(3)
Ø. The older we grow, the poorer our memory will be.
Ø. The earlier we start, the sooner we’ll get there.
笔记要点：这种句型结构表示“越...... 越…… ”
(4)
Ø. I prefer the cheaper one of the tow books.
Ø. Of the two brothers, he is the cleverer.
笔记要点：二者之比较。而Of the three girls, she is the cleverest.
最高级构成方式：
三者或三者以上进行比较， “the + 形容词/副词est”。
(1) John is the tallest of the three.
He runs fastest in our class.（副词的最高级the可省略）
This is the most difficult book I’ve read.
(2) He is cleverer than any other boy in the class.（有than时只用比较级）
She is younger than all the other students. |
