一般现在时与三单(综合)
时态一：一般现在时／动词第三人称单数
一、定义： 1、经常性、习惯性的动作；
2、事物或人物的特征或状态；
3、客观现实、真理或规律。
Example：
1.表示经常性、习惯性、永久性、频率性的动作，通常与副词 often, usually, always, every day (year/ month ), once (twice, three times) a day（ week/moth/year） , sometimes， in the morning/afternoon/evening， on Sundays等时间状语连用。
They usually go to school by bike.
I take the medicine three times a day.
She helps her mother once a week.
2.表示事物或人物的特征、状态
Mary’ s father is a policeman.
There are 50 students in my class.
3.表示客观真理，科学原理，自然现象等客观事实或格言、谚语等。
The sun rises in the east and sets in the west every day.
The man who has never been to the Great Wall is not a real man.
Tomorrow is Tuesday.
二、结构：
肯定句：主语+ v原/v“三单”(主语 + Be/情态动词 /行为动词（原形或三单） +其它 )
句型Be 型（情态动词型）
否定句主语 + Be 动词 /情态动词 +not
Be 动词 /情态动词 +主语 +其它
肯定回答：
一般疑问句Yes，主语 + Be 动词 /情态动词 .
否定回答：
No, 主语 + Be 动词 /情态动词 +not.
Do 型
主语 + don’t/doesn’t V+ 原形Do/Does+主语 + V原形
肯定回答：
Yes，主语 + do/does.
否定回答：
No, 主语 + don’t/doesn’ t.
否定句：主语 +Be/情态动词 /do/dose+not+其它
一般疑问句： Be/情态动词 /do/dose + 主语 +其它
特殊疑问句：特殊疑问词 + Be 动词 /情态动词 /do/dose + 主语 +其它（对主语提问除外）对主语提问的特殊疑问句 = 特殊疑问词 +主语 +动词原形 /三单（肯定句的结构） +？
总结：行为动词表示具体的动作， be 动词表示状态，情态动词表示态度。在做肯定陈述
的时候，运用的规则是：有 do 无 be；无 do 一定要加 be。
另外，一定要小心：在做句型转换（否定、疑问）的时候，要分别遵守自己的约定：行
为动词要请 do/does帮忙；有 be 就直接用 be(be 提前变成问句，在后面加上not 变成否定句 )。
三、第三人称单数（三单）
1、除了我（I）和你(you )我们（we）你们(you)他们(they)之外都是三单 ,人称代词 he, she, it是第三人称单数。如：
He likes watching TV. 他喜欢看电视。
She has lunch at twelve. 她十二点吃午餐。
It looks like a cat. 它看起来像只猫。
2、单个人名、地名或称呼作主语；是第三人称单数。如：
2 /17
Beijing is in China. 北京在中国。
Uncle Wang often makes cakes.王叔叔经常做蛋糕。
3、单数可数名词或"this / that / the+单数可数名词"作主语时，是第三人称单数。如：
A horse is a useful animal. 马是有用的动物。
This book is yours. 这本书是你的。
That car is red. 那辆小汽车是红色的。
The cat is Lucy's. 这只猫是露茜的。
4、不定代词someone,somebody,nobody, everything, something等及指示代词this, that 作主语时，是第三人称单数。如：
Everyone is here. 大家到齐了。
There is something wrong with the watch. 这块手表有毛病。
This is a pen. 这是一支钢笔。
That is an eraser. 那是一块橡皮擦。
5、不可数名词作主语时为第三人称单数。如：
The milk is in the glass. 牛奶在玻璃杯里。
The bread is very small. 那面包很小。
6、当数字或字母作主语时，看作第三人称单数。如：
"6" is a lucky number. "6"是个吉利数字。
"I" is a letter. "I" 是个字母。
四、动词三单变化规则
1、一般情况下加S ：
ask---asks learn----learns work---works get---gets like — likes
play— plays stay---stays
2、以“ s, x, ch, sh,o”结尾的，在词尾加“ es”：
teach－teaches wash----washes go－ goes do－ does
3、以辅音字母加“ y”结尾的，先将“ y”变为“ i”，然后在加“ es”：
study－studies fly －flies cry---cries try---tries carry－carries worry －worries 4、以元音字母加 Y 的，直接加 S，（此种情况可直接归入第 1 类）
如say—says
5、记住 3 个特殊的：
Be 动词（ is are）的三单－ is
have 的三单－ has
Do 的三单— does
五、句型转换
一、陈述句变一般疑问句、否定句
1、Be 型、情态动词型
否定句：直接在be 动词或情态动词后面加not.
疑问句：则把 be 动词或情态动词 (can,could 等等 )提到主语的前面例：①陈述句： She is a student.
疑问句→ Is she a student?
否定句→ She is not a student.
②陈述句： I can swim.
疑问句→ Can you swim? yes,I can.No,I can ’t.
否定句→ I can not swim.
2、Do 型
否定句：主语+ don’t/ doesn+ ’谓t语动词原形
疑问句： Do / Does + 主语 + 动词原形
例：①陈述句： We get up at 7:00 every morning.
否定句→We don’t get up at 7:00 every morni g.
疑问句→Do you get up at 7:00 every morning?
②陈述句： She has a little brother.
否定句→ She doesn ’t have a little brother.
疑问句→ Does she have a little brother?
3、注意“变变变变”
（1） I、 we—>you、you
（2）句号变问号；
（3） Does（三单）、Did （过去式）来帮忙，动词变 V 原；
（4） some->any
already->yet
both->neither something->anything somebody-> anybody too->either
all->none
eg:
Are you from Japan﹖Yes, I am． / No, I'm not．
Is her sister doing her homework now﹖Yes, she is． / No, she isn't．Does he work in a bank﹖Yes, he does． / No, he doesn't．
Do you live near your school﹖Yes, I do． / No, I don't．
Can you speak French﹖Yes, I can． / No, I can't．
May I go home now﹖Yes, you may． / No, you mustn't．
二、陈述句变特殊疑问句（不能用yes/no 回答的疑问句）
1、常见的疑问词
when：问时间(回答用 At/ On...等 )
where：哪里（状语）
who ：谁 ( 回答用 He is...She is... They are...等）
whom：谁（宾格）
whose：谁的 (回答用 It is.. These/Those are等 )
what ：什么
How：怎么样(对近况提问，回答用形容词，问程度）
which：哪一个，哪个
why：为什么(回答用 Because，问原因 )
记法：特殊疑问词的开头一般是wh 或 h；
注意：特殊疑问句一般读降调( ↓)
常见的疑问短语
what time：问时间点
what color：什么颜色（表语）
what weather：什么天气
what subject：什么学科
what job：什么职业
what nationality ：对国籍提问
what kind：哪一种类型
-
How fast：多快（速度）
How many：多少数量（可数）
How much：多少钱价格（不可数）
How long ：多长 (可用于时间，问做多长时间）
How often ：多少次（问频率）（频率副词）
How far ：多远路程
How soon：多久
How old ：多少岁
2、特殊疑问句有两种语序：
(1)如疑问词作主语或主语的定语，即对主语或主语的定语提问，其语序是陈述句的语序：
Who is singing in the room﹖
whose bike is broken﹖
(2)如疑问词作其他成分，即对其他成分提问，其语序是：特殊疑问词+一般疑问句【即：特殊疑问词 +be/助动词 /情态动词 +主语 +谓语】
What does she like?
What class are you in﹖
Where are you from﹖
What time does he get up every morning﹖
How do you know ﹖
(3)就划线部分提问解题方法：一换二变三提前
一换：找出正确的疑问词或词组替换划线部分
什么东西 ->what, 地点 ->where时间->when,怎么样->how
多少 ->how many(可数 )how much(不可数 )
动作划线 ->看形式，然后选择助动词，做的事情用 what Eg: They read English books in the afternoon. What
They read English books in the classroom every day. Where
They read English books in the classroom in the morning. When
I have got five books. How many
I go to school by bike every day.How
Tom sings songs in the living room every evening. does what
We read books every day. do what
二变：将替换完的句子根据规则变为一般疑问句
eg: Tom swims in the pool every day.
Tom does what in the pool every day.
Does Tom do what in the pool every day?
三提前：将变完的一般疑问句中的特殊疑问词提前
eg: Does Tom do what in the pool every day?
What does Tom do in the pool every day?
注意： I like taking photo in the park.
I like doing what in the park.
What do you like doing in the park?
