一.动词be(is,am,are)的用法:说明身份,年龄,状态等。
口诀:
我(I)用am, 你(you)用are,is跟着他(he),她(she),它(it)。
单数名词用is,复数名词全用are。
变否定,更容易,be后not加上去。
变疑问,往前提,句末问号莫丢弃。还有一条须注意,句首大写莫忘记。
be动词的用法:
be动词包括“am”, “is”, “are”三种形式。
第一人称单数(I)配合am来用。
句型解析析:I am+…
I am a student. I am a boy.
第二人称(You)配合are使用。
句型解析:You are+…
You are my good friend. You are a good person.
第三人称单数(He or She or It)配合is使用。
句型解析:She(He, It) is +…
She is a good girl. She is so cute.
人称复数 (we /you/they)配合are使用。
句型解析:We (You, They) are +…
We are in Class 5,Grade 7. You are good students.
注意:
1 综合解析当使用be动词的时候,前面请先加上第几人称。
be动词前面的人称,是不可随意替换的。例如:
I am, You are, She is,并不会出现I is, You am, She are 这样的情形。
2 当只有第一人称和第二人称或第三人称时应该把第二人称或第三人称放在前
例如:you and I, Tom and I
当第二人称和第三人称放在一起时把第二人称放在前面,
例如:you and Tom
当三者都有时,排序为:2 3 1
例如you, Tom and I
练习:1. Where ______ Ann . She ______ here.
2. How old ______ you . I ______ thirteen.
3. ______ you Mr Read . Yes, I ______.
4. What ______ your name. My name ____ Ann
补充知识点:
一.this,that和it用法
(1)this和that是指示代词,it是人称代词。
(2)距离说话人近的人或物用this, 距离说话人远的人或物用that。如:
This is a flower. 这是一朵花。(近处)
That is a tree. 那是一棵树。(远处)
(3)放在一起的两样东西,先说this, 后说that。如:
This is a pen. That is a pencil. 这是一支钢笔。那是一支铅笔。
(4)向别人介绍某人时说This is…, 不说That is…。如:
This is Helen. Helen, this is Tom. 这是海伦,海伦,这是汤姆。
(5)This is 不能缩写, 而That is可以缩写。如:
This is a bike. That’s a car. 这是一辆自行车。那是一辆轿车。
(6)打电话时,介绍自己用this, 询问对方用that。如:
—Hello! Is that Miss Green? 喂,是格林小姐吗?
—Yes, this is. Who’s that? 是的,我是,你是谁?
注意:虽然汉语中使用“我”和“你”,但英语中打电话时绝不可以说:
I am…, Are you…?/Who are you?
(7)在回答this或that作主语的一般疑问句时, 要用it代替this或that。如:
①—Is this a notebook? 这是笔记本吗? —Yes, it is. 是的,它是。
②—What’s that? 那是什么? —It’s a kite. 是只风筝。
二. these和those用法
this, that, these和those是指示代词,
these是this的复数形式,指时间,距离较近的或下面要提到的人或事;
those是that的复数形式,指时间、距离较远或前面已经提到过的人或事物。
①This is my bed. That is Lily’s bed. 这是我的床。那是莉莉的床。
②These pictures are good. 那些画很好。
③ Are those apple trees? 那些是苹果树吗?
在回答主语是these或those的疑问句时,通常用they代替these或those以避免重复。
④Are these/those your apples? 这些(那些)是你的苹果吗?
Yes, they are. 是的,他们是。
三.不定冠词a和an
a和an都是不定冠词,表示一(个,支,本,块……)的意思,但不强调数量概念,而是强调类别,用来限定名词。
a用在辅音素开头的单数名词前,如:a pencil(一支铅笔),a book(一本书);
an用在元音音素开头的名词前,如an eraser(一块橡皮)。如果名词前有修饰语,
用a还是用an,则以该修饰语的第一音素决定用a还是用an。如:
a clock 一座钟 an old clock 一座旧钟 a book 一本书 an English book 一本英语书
a nice apple 一个可爱的苹果 an apple 一个苹果
用不定冠词a或an填空,不需要的填(/)。
1. This is ____________ book.
2. This is ____________ English book.
3. That is ____________ orange.
