物主代詞人教版英語七年級上冊

物主代詞物主代詞是表示所有關(guān)系的代詞，可分為形容詞性物主代詞和名詞性物主代詞。形容詞性物主代詞起形容詞的作用，用在名詞前作定語，這在Unit1已經(jīng)學(xué)習(xí)過了。本單元我們要學(xué)習(xí)的名詞性物主代詞起名詞的作用，相當(dāng)于“形容詞性物主代詞+名詞”，意為“……的”。如：Thisismyjacket.Thatis

yours.(yours=yourjacket)Myquiltiswhite.

Hers

isyellow.(Hers=Herquilt)【溫馨提示】同學(xué)們可通過對比來記憶物主代詞。形容詞性物主代詞名詞性物主代詞mymineouroursyouryourshishisherhersitsitstheirtheirs注意：多數(shù)名詞性物主代詞是在形容詞性物主代詞后面加?s構(gòu)成；有兩組形容詞性物主代詞和名詞性物主代詞的形式相同：his和its；有一組形式完全不同：其形容詞性物主代詞形式為my，其名詞性物主代詞形式為mine。【鏈接】本單元出現(xiàn)的Bob's，Helen's表示“鮑勃的”，“海倫的”。's為名詞所有格(表示所有關(guān)系)，意為“……的”。它們可單獨使用，相當(dāng)于名詞性物主代詞；也可后跟名詞，相當(dāng)于形容詞性物主代詞?！揪毩?xí)】Ⅰ.
