Unit 1 This is me!
语法专项
语法概览
☆一般现在时(be动词)
★指示代词(this/that/these/those)
语法精讲精练一
1.定义与功能
一般现在时(be动词)用于描述事实、状态或经常性的情况。be动词(am/is/are)在句中充当系
动词,连接主语和表语(名词、形容词、介词短语等),表示“是…”“在…”“成
为…”等含义。
核心考点:b动词本身要随主语的人称和数变化,不能省略,且不能与实义动词原形直接
连用。这是初一最基础的易错点。
2.基本结构(四大句型)
句型
结构
示例
I am a student./She is from Nanjing.
肯定句
主语+be(am/is/are)+表语.
They are in the library.
I am not a student./He isn't from
否定句
主语+be+not+表语.
Nanjing.They aren't in the library.
Are you a student?/Is she from Nanjing?
一般疑问句
Be+主语+表语?
Are they in the library?
What is your name?/Where are they?/
特殊疑问句
疑问词+be+主语+表语?
How old is he?
考点强化:
一般疑问句回答必须用“Yes,主语+be.”或“No,主语+be+not.”(肯定回答中be不缩
写,否定回答中可缩写)
例:一Are you Lily?一Yes,Iam./No,I am not.(不能说Yes,Im.)
特殊疑问句先确定疑问词,再跟be动词和主语,不能用“助动词+主语”结构(因为be动词
本身就是系动词)。
3.主语与be动词的搭配(必背表格)
主语人称
be动词
缩写形式(肯定)
缩写形式(否定)
I
am
I'm
I'mnot(无缩写)
he/she/it/单
iS
he's she's it's
isn't
数名词
we/you /they/
are
we're you're they're
aren't
复数名词
易错点:
am与not不能写成aimt(不规范),必须分开写:I am not。
is not常缩写为isnt,are not常缩写为aren't。
主谓一致:单数主语(he,she,t个人名,单数事物)用is;复数主语(they,复数名词)用
are;I用am。
4.用法细节与常见搭配
用法场景
例句
说明
表示身份/特
He is a doctor./The sky is blue.
be+名词/形容词
征
表示年龄
My sister is twelve years old.
be+数字+years old
表示地点
Her books are on the desk.
be+介词短语
表示时间/日
It is seven o'clock.Today is Monday
it作主语
期
表示天气/温
t作主语
度
It is hot in summer.
表示状态/情
We are happy to see you
be+形容词
绪
考点强化:
询问年龄时用“How old+be+主语?”
询问地点时用“Where+be+主语?”
询问时间时用“What time+be+主语?”或“What day+be+主语?”
5.易混考点辨析(中考必考)
①be动词vs实义动词
be动词后不能直接跟动词原形,必须跟名词、形容词、介词短语或V-ing(进行时态,但初
一下才学)。
实义动词(如like,have,go)有自己的变化,不能与be动词重复。
正:He is a teacher../He likes music.
误:He is like music.(应去掉is)
误:He likes a teacher..(应改为is)
②there be句型(初一下学期重点,此处仅作提醒)
“有.”用“There is/are+名词+地点”,与“拥有”的have/has不同。
例:There is a book on the desk.(桌子上有一本书。)
例:I have a book.(我有一本书。)
③否定句与疑问句中not的位置
否定句:be动词后直接加not,不能分开。
正:She is not at home.
误:She not is at home
一般疑问句:be动词提到主语前,句末加问号。
正:Is she at home?
误:Does she is at home?(be动词不用助动词do/does)

语法精讲精练二
1.指示代词的定义与功能
指示代词(Demonstrative Pronouns)用来指代人或事物,在句中可作主语、宾语、定
语。
核心功能:表示“近指”或“远指”,同时区分单数和复数。
单数
复数
距离含义
近指(指离说话人近的人或
this
these
物)
远指(指离说话人远的人或
that
those
物)
【考点】this/these常与here连用,that/those常与there连用。
This book here is mine./That car over there is Tom's.
2.指示代词的三大基本用法
(1)作定语(修饰名词,最常考)
√结构:this/that/these/those+名词
√名词的单复数必须与指示代词一致:
this/hat→可数名词单数/不可数名词
these/.those→可数名词复数
近指
远指
名词形式
this pen
that pen
单数
these pens
those pens
复数
★易错点:
This is a book.(this作主语)
This book is interesting.(this作定语,修饰book)
→学生常混淆“this is'”和“this book”,需注意句子成分。
(2)作主语(单独指代人或物)
√结构:This/That/These/Those+动词
单数→动词用单三(is/was/has)
复数→动词用复数(are/were/have)
例:
This is my teacher.
These are my classmates.
★考点:回答时单数用it/that,复数用they/hose
What's this?->It's a pencil./That's a ruler
What are these?>They are apples./Those are oranges
(中考常考回答中主语的选择,不能直接用this/hat回答)
(3)作宾语(放在动词或介词后)
√结构:动词/介词+this/that/these/those
例:
I like this very much.
Please look at that.
Can you help me with these?
【注意】作宾语时一般指代上文提到的事物,避免重复。
例:I bought a new bag.Do you like this?(this指代刚买的bag)
3.特殊用法与易混考点
(1)电话用语中的this/hat
介绍自己:This is+姓名/This is+身份+speaking
询问对方:Who is that?/Is that+姓名+speaking?
例:
-Hello!This is Mike.Is that Mr.Smith?
-Yes,this is Mr.Smith speaking.
口诀:我是his,你是that(电话中称呼自己用this,称呼对方用that)
(2)that/those代替前面提到的事物(避免重复)
结构中常用that of.…或those of比较两个事物。
例:
The weather in Beijing is colder than that in Nanjing.
(that代替weather,.避免重复)
The books on the desk are newer than those on the shelf.
(those代替books)
【考点】初中阶段仅了解即可,不要求深入。
(3)this/that可指时间
this指“今天、今年、这个月”等当前时间。
-this morning this week this year
hat指“过去或将来某个时间点”。
that day that evening /that year
例:
I met him this morning.(今天早上)
That evening we had a party.(那天晚上)
4.两个常错点(中考基础题)
①his/these与here,that/those与there搭配
These books here are new.
That cat over there is cute.
X不可写成“This here book”,这是口语错误用法。
②单复数一致
This apple is red.
These apples are red.
X不能说“This apples are red.”或“These apple is red.”
