物主代词
表示所有或所属关系的代词,叫物主代词,也称代词所有格。物主代词分为名词性物主代词和形容词性物主代词两种。
形容词性
物主代词
my
your
his
her
our
your
their
名词性
物主代词
mine
yours
his
hers
ours
yours
theirs
物主代词用法如下:
(1)形容词性物主代词必须置于名词前,修饰限定名词,作定语。
e.g. —What’s your name? 你叫什么名字?
—My name is Jane. 我叫简。
(2)名词性物主代词相当于“形容词性物主代词+名词”,在句子中主要是作主语、宾语和表语。
e.g. —Is this pen yours? 这支钢笔是你的吗?(表语)
—No, it isn’t. It`s his. 不,不是。是他的。(表语)
Mine is on my desk. 我的在我的课桌上。(主语)
She knows my name and I know hers. 她知道我的名字,我也知道她的名字。(宾语)
(3)名词前若有形容词性物主代词,不可再出现a,an, the, this, that, these, those之类的限定修饰词。如果要表示这种意义,则用“of+名词性物主代词”这种结构。
e.g. a friend of mine 我的一个朋友
(4)whose既是形容词性物主代词,又是名词性物主代词。
e.g. Whose is this book?这本书是谁的?(名词性物主代词)
Whose book is this?这是谁的书?(形容词性物主代词)
help sb.(to)do sth.帮助某人做某事,“to”可以省略
He helps me (to)learn English.
【重点短语】
1. give sb. sth. = give sth. to sb.把某物给某人
Please give it to her.
2. look the same 长相相同
look different 长相不同,看起来不一样
3. look like 看起来像
He looks like his father. = He and his father look the same.
4. next to 在……旁边
The boy next to me is my good friend.
5. in +颜色 穿着……颜色的衣服
in +a/an +颜色+衣服 穿着……颜色的……
The boy in a yellow T-shirt and gray pants is my good friend.6.
(1) both两者都(be动词之后,实义动词之前)
They both have brown hair and black eyes.
They are both office workers.
(2)all 三者或三者以上都
They are all kind to me.
7. 数字+(形状、大小)+颜色+n.

【重点语法】
1. 动词原形和动词第三人称单数形式
(1)主语是第三人称单数形式(he、she、it;单一的人;单一的名字;单一的事物),动词要用单三形式。实义动词变第三人称单数的规则:
① 一般情况直接加“s”,如:come---comes,meet---meets
② 动词以o,s,sh,ch, x结尾,加“es”,如:do--does; go--goes; teach--teaches
③ 以辅音字母+y结尾,变y为i,再加es, 如:study--studies, fly--flies, try--tries
④ 特殊情况:have--has
