动词be的一般现在时
我们常用动词be的一般现在时谈论事实和状态。
例如：I am from China.
He is 12 years old.
We are very happy.
注意：主语可以是人称代词,也可以是名词，动词be要与主语保持一致。
例如：
The little dog is very cute.
These apples are big and red.
1. 如果主语是代词，在非正式行文中，动词be与前面主语可以缩写。如：
I am=I’m You are=You’re She is= She’s He is=He’s
It is=It’s We are=we’re They are=they’re
2. 动词be一般现在时的否定句式是在be后面加not.
例如：She is not tall.
They are not in the classroom.
在非正式行文中，动词is/are与not可以缩写。如：is not=isn’t 、are not=aren’t。
3. 动词be一般现在时的一般疑问句式是将be提前至句首。
例如：—Are you still in Grade 7?
—Yes, I am.
—Is Tom your classmate?
—No, he isn’t.
注意：am与not不能缩写。
在肯定答语中，主语和动词be不能缩写。如“Yes, he is.” 不能缩写成 “Yes, he’s.”

行为动词的一般现在时
用一般现在时谈论我们经常做的事，目前的爱好、能力等以及不受时限的客观事实。这时我们常使用行为动词，这种动词有具体、实际的含义。
试比较：
They are hard-working students.
They work hard.
注意：当我们用一般现在时进行表达的时候，不能同时使用动词be和行为动词。
例如：I am from China. √
I come from China.√
I am come from China. ×
1. 行为动词的一般现在时可用于以下情况：
1） 经常性、习惯性的动作
例如：I go to school at 7 o’clock every morning.
2） 目前的爱好、能力等
例如：She sings very well.
3） 不受时限的客观事实。
例如: Fish live in water.
根据主语的人称和数的不同，行为动词的一般现在时有两种形式。
①主语为第一、二和三人称复数时，行为动词使用其原形。
例如：
We have lunch at school.
My parents watch films at weekends.
②主语为第三人称单数时行为动词使用其第三人称单数形式。
例如：
She does her homework in the evening.
He plays football every day.

2. 行为动词一般现在时的第三人称单数形式构成方法如下：
2. 行为动词一般现在时的否定式：
do not/does not + 行为动词
非正式行文中：
do not=don’t
does not= doesn’t
例句：
Students do not go to school on Sunday.
He does not work in this shop.
3. 行为动词一般现在时的疑问句式：
do/does +主语+其他
例如：Do you play basketball after school?

注意：在疑问句和否定句中，助动词之后的行为动词均用原形。
4. 区分行为动词do和助动词do的用法

可数名词和不可数名词
名词分为两种：可数名词和不可数名词
1. 不可数名词通常指以量计算或作为整体的事物。如water或time。不可数名词无单、复数之分。前面无限定词均可。
例如：
Her hair is very long.
Do you have paper?
2. 可数名词，顾名思义，即可以用数目计算的人或事物，指一个人或一件事物时，用单数形式；指两个或多个人或事物时用复数形式。
例如：I am a student.
They love these children very much.
3. 可数名词单数变复数表格
规则
举例
读音变化
大多数+s
book-books
chair- chairs
清辅音后的s读[s];
浊辅音或元音后的s读[z]
以ch, sh, ss或x结尾的词后+es
bus-buses
box-boxes
watch-watches
brush-brushes
es读[Iz]
注：以th结尾的可数名词不适用此规则，如：month-months
以辅音字母+y结尾的动词，去y, +ies
family-families
ies读[Iz]
注：若是元音字母+y结尾，不用此规则。如：boy-boys
以o结尾且表示人或农作物等有生命的事物的词+es
go-goes
es读[z]
注：以O结尾但表示无生命的事物的单词不适用此规则。如：radio-radios
以f或fe结尾的词，去点f或fe，+ves
knife-knives
shelf-shelves
ves读[z]
特殊变化
man-men
foot-feet
child-children
fish-fish
由man或与另一个单词组成的复数名词变为复数时，两部分都发生变化。如： women drivers
men doctors
4. 易误用的不可数名词：time, money, work, homework, news, luck等。
5. 如果主语是不可数名词，动词常用单数。
例如：Coffee is a kind of drink.
6. 作单数的可数名词或名词短语前一般有限定词，如：冠词a/an，the；指示代词this， that;形容词性物主代词my, your, his, her, their 等；名词所有格John’s等。
注意：冠词a用于辅音音素开头的可数名词前；an 用于元音音素开头的可数名词前，而不是元音字母开头的名词前。
例如： Mary is an American.
She is an honest girl.
She has an umbrella and a useful book.
7. 不可数名词前不能用a/an或表示具体数量的数词。但可以用the, some,much, a little, little, a lot of 等词或词组修饰，表示数量的多少。
例如：a lot of water
8. 不可数名词前还可以用表示量的可数名词+of短语来表示数量。
例如：a piece of paper three cups of coffee five kilos of meat

Mum: OK. We can also buy a few_______of_________(几瓶果汁）.
可数名词单数
可数名词复数
不可数名词
7AU7
用some和any表示数量
用some和any这样的不定数或不定量的词来修饰名词。
1. Some和any表示“一些”，既可修饰可数名词，又可修饰不可数名词。
例如：There are some books on the desk.
I want some juice.
There are not any oranges in the shop.
Do you have any good news?
2. Some长用于肯定句中，any常用于否定句或疑问句中。
例如：He has some interesting computer games.
He does not have any interesting computer games.
Does he have any interesting computer games?
注意：在疑问句中，我们在提出建议或请求时常用some，表示希望得到对方的肯定答复。
例如：Can you pass some sugar to me?
Would you like some drink?
There be结构
我们常用“there be”结构来表示“某地有某物或某人”。
例如: There is a computer in the reading room.
There are a lot of people in the park at weekend.
There is not any meat in the fridge.
Are there any girl students in the classroom?
1. There be 结构中，动词be的形式与后面名词一致。后面的名词如果是可数名词单数或不可数名词，动词be用is；后面的名词如果是可数名词复数，动词be用are.
注意：当there be后面有两个或两个以上名词时，动词be要与离它最近的名词一致。
例如：There is a girl and two boys under the tree.
There are two boys and a girl under the tree.
2. There be结构的否定句式是在动词be后加not；一般疑问句式是把动词be调到句首，应答时可以说：Yes, there is/are 或 No, there is/are not.
3. 注意区分there be和have的用法。There be结构表示“存在”，而have表示“拥有”。
例如：There is a picture on the wall.
I have some pictures.
练习
用there be的正确形式填空。
My school is very beautiful, and______________some shops around it. _________a bookshop near my school. ________________a lot of good books in it. ______________also some pens, rubbers and exercise books. Sometimes we go there after school.__________________hair clips, music boxes and some other nice things too. We can buy presents for our friends in the shop. Not far away from my school,_____________also a supermarket. It is not very big, but_________________enough snacks in it.
7AU8
现在进行时
用现在进行时表示“某人正在做某事”
例如：I am watching TV in my bedroom.
My grandfather is reading newspaper.
Boys are not playing in the playground now.
—Are you doing your homework?
—Yes, I am.
1. 现在进行时可以表示说话时正在进行或发生的动作，也可表示当前一段时间内的活动或现阶段正在进行的动作。
例如：We are waiting for you here.
Tom is making a model plane all the afternoon.
We are working hard this term.
2. 如果句子带有鲜明的时间状语，如Now（现在），或带有Look和listen等暗示词或有表示现在的上下文语境，我们常用现在进行时。
例如：My mum is cooking dinner now.
Listen! Our teacher is singing an English song.
—Where is your father?
—Oh, he is cleaning his car.
注意：有些名词一般不用于进行时，如：know, understand, love, like, want, hope, hear, see等。
3. 现在进行时的基本结构时主语+be+v-ing（动词的现在分词），动词的变化规则如下：
规则
举例
大多数动词后加ing
go-going
以不发音的e结尾的动词，去掉e，再加ing
take-taking
以ie结尾的动词，变ie为y,再加ing
die-dying
以一个辅音字母结尾的重读闭音节动词，双写最后一个辅音字母，再加ing
get-getting
swim-swimming
注意：重读闭音节首先必须是重读音节，同时这个音节是两个辅音中间夹一个元音的结构。
4. 现在进行时的否定句式是在be后面加not, 构成主语+be+not+v-ing结构。
例如: The students are not having lunch.
5. 现在进行时的一般疑问句式是把be提前至句首。
例如：
—Is that girl asking you questions?
—Yes, she is.
6. 现在进行时的特殊疑问句式是疑问词+be+主语+v-ing。
例如：
—What are you reading?
—I’m reading a book about colours.
