一.教学目的:There be 句型结构的一般疑问句和特殊疑问句；名词的复数形式和一些日常用语。
二.教学重点:There be句型结构的一般疑问句和特殊疑问句。
三.重点难点讲解:
1.there be句型结构的肯定形式, 否定形式, 疑问形式和回答。
肯定形式，在there be 后接单数或复数可数名词或不可数名词。例如：
There are fifty-three students in our class.
我们班上有五十三名学生。
否定形式，there be + not 构成。例如：
（1）There isn’t any student in the classroom.
教室里没有一个学生。
（2）There aren’t any maps or pictures on the wall.
墙上没有地图，也没有画。
* 在否定句中，并列成分一般用or 来连接，而不用and。
疑问形式及回答， 疑问形式是把be动词放在there前，句尾加问号，肯定回答为Yes, there is/are; 否定回答中，应用isn’t 和aren’t缩写形式，而一般不分开写。例如：
“Is there a house near the river?”
“Yes, there’s one.”
“河边有房子吗？”“有一间。”
There be的特殊疑问句中，请注意be动词的位置。例如：
How many boats are there in the river?
河里有多少条船？
How much rice is there in the bag?
袋子里有多少大米？（大米本rice为不可数名词，故要用much来修饰）
注意，特殊疑问句不能用Yes或No来回答，而要用具体回答。
There be的句型中，我们常常要用到一些壮语的介词短语，请大家注意平时的积累。
2．名词复数
英语的名词分为可数名词和不可数名词。可数名词有其复数形式，构成形式有以下几种情况：
（1）一般在词尾加s，例如：map-maps tree-trees
（2）以s, sh, ch, x等结尾的次加es, 例如：watch-watches box-boxes
（3）以辅音字母+y结尾的词，变y为i，再加es, ；例如：baby-babies family-families
（4）以f或fe结尾的名词，将f或fe改为ve, 再加s, 例如：knife-knives
（5）英语中还有为数不多的名词的复数形式是不规则的，例如：
woman-women child-children man-men
3．at work
at work可理解为“在上班”，“在工作”等，值得注意的是名词work前不用定冠词the。类似的词组还有：
go to work 去上班 come back from work 下班
go to school 去上学 at school 在学校
in school 在读书 after school 放学以后
in class 在课上 go to class 去上课
before/after class 课前/课后 at home 在家
in bed 在睡觉
以上这种名词前不带定冠词the的情况，主要是表示人的身份，即人与职业的关系，学生和学校或课堂的关系。如果不具有这种关系，则应带the。试比较：
When do you go to school every day?
你每天什么时候上学？ （I是学生）
I go to the school to see my daughter.
我去学校看望我的女儿 。（I不是学生）
* at work/school 中的介词at具有正在进行的含义，表示人正处在的状态。At work 还可用来表示某事物“正在运转”、“正在起作用”。如：
My father isn’t in. He is at work.
我父亲不在家，他在工作。（上班）
四．练习
1．写出下列名词的复数形式。
knife baby
child house

box boy

(3) She can’t go with us. She’s .
A work B at work C at the work D works
(4) Could you give the old woman bread?
A some B any C many D much
(5) can you see in the picture?

3.翻译句子

(2) 他们班有多少名学生？有48名。
(3) 桌子上有一本书吗？是的，有一本。
五．答案
1．knives babies
children houses
oranges women
boxes boys
2. (1) C (2) A (3)B (4) A (5)C
(1) There is a desk and two beds in that room.
那间屋里有一张书桌和两张床。(There be句型中的be 要采取就近原则，与主语a desk离的最近，所以用is. 这句话如果将a desk 和two beds 调换，则动词be 要用are, 即：There are two beds and a desk in that room.)
(2) There are two bags of rice on the floor.
地板上有两袋大米。（注意量词上的复数变化）
(3) She can’t go with us. She’s at work.

章节 第二十一单元
关键词 内容
【 抛砖引玉 】
单元双基学习目标
Ⅰ. 语音学习
字母组合tr , dr , t ( e ) s , d ( e ) s的发音。
Ⅱ. 词语学习
house , men , women , child , children , work , young , at work , pioneer , Young Pioneer
Ⅲ. 语法学习
掌握名词复数的不规则变化。
man → men , woman → women , child → children
Ⅳ. 交际英语
1 . Where are they ? They're at school ( home , work ) .
2 . How many boys are there ? I think there are ten .
【 指点迷津 】
单元重点词汇点拨
1 . house 房子
There is a house near the river .
Our new house is different from yours in colour .
〖 点拨 〗 house 的复数为 houses , 其读音为［&127;h?÷?÷］，house 指的是用来居住的所有建筑物，包括 room ( 房间 ) 、浴室、起居室等。
2 . women 是 woman 的复形式
I don't know how many women will come to the tea party . 我不知道有多少位妇女会来参加茶话会。
〖 点拨 〗 women 的发音比较特殊。注意其单数与复数的变化。又如：man - men男人。
3 . children 是 child 的复数形式
The children in that family are all at school . 那家的孩子们都在学校里上学。
Children of school-age must go to school . 学龄儿童必须上学。
〖 点拨 〗 注意其发音和单复数的变化。
4 . work 工作，劳动
Work hard and be a good boy . 努力学习，做个好孩子。
You should work hard at English .
What time do you go to work every day ? 每天你什么时候上班 ?
〖 点拨 〗 作 “ 工作 ” 解，work 为不可数名词。上班 go to work , 下班 after work 。 work hard at 努力干 ……
We go to work at 7：30 .
5 . pioneer 先锋
They are pioneers of our farm . 他们是我们农场的开路先锋。
〖 点拨 〗注意该词的发音和拼写。the Young Pioneers少先队员。
单元词组思维运用
1 .已经学习的介词短语回眸
in the river 在河里 / in the tree 在树上 / in the picture 在图片里 / in Row 1在第一排 / in Class 3 , Grade 1 在 1 年级 3 班 / at home 在家里 /at school 在学校里 / in the workbook 在练习册里 / on the desk在书桌上 / behind her chair在她的椅子后面 / under the chair 在椅子下面 / in her pencil - box 在她的铅笔盒里 / on the floor在地板上 / in your desk 在你的桌子里 / at Li Lei's bedroom 在李雷的卧室里 /on the wall 在墙上 /under the window 在窗下 / behind the door 在门后 / in Hebei 在河北 / in your bag 在你的书包里 ( 袋子里 ) / under your bag 在你的书包下面 ( 袋子下面 ) / on the hill 在山上 / under the black bike 在黑色的单车上 / behind the tree 在树后 / in the box 在盒里子 / on the clothes line 在晒衣绳上 / on the bed 在床上 / in the car 在轿车里 / near the river 在河边
2 . in our classroom 在我们的教室里
Who is in our classroom ? 谁在我们的教室里 ?
There is a map of China in our classroom . 我们教室里有一张中国地图。
We are having a lesson in the classroom . 我们正在教室里上课。
3 . on the teacher's desk 在讲台上
There are some flower on the teacher's desk .
4 . near the door 在门边
Don't stand near the door . 别站在门边。
The student near the door is Li Ming . 门边的那个学生叫李明。
5 . at work 在工作，在上班
She is always at work on Sundays . 她星期天总是在工作。
介词 at 在这里是 “ 从事 ”。如 What are you at ? 相当于 What are you doing ? ( 你正在干什么 ? )
二、学海导航
【 学法指要 】
单元句型思路明晰
1 . 存在句
There be + not + 主语 + 其他
There isn't any light in the room . 房里一点灯光也没有。
There aren't any lesson this morning . 今天上午没有课。
There is no fire without some smoke . 有火必有烟；有利就有弊。
Be there + 主语 + 其它 ?
Are there any apples in the basket ?
Is there a bird in the tree ?
Is there enough time for me to do all the homework ? 我要做完全部的作业时间够吗 ?
对这类句型的回答可根据实际情况选择肯定回答或否定回答。
肯定回答为：Yes there is/are .
否定回答为:No , there isn't/aren't ( any ) 。
3 . 问有多少的句型
How many + 可数名词复数 + are there + 其他 ?
How many days are there in a week ?
How many students are there in your school ?
How many policemen are there in the street ?
how many 是对可数名词进行提问，对不可数名词用 how much 。如：How much time do you spend ?
单元重点难点释疑
1 . Behind the house there is a tree . 在房子后面有一棵树。
behind the house “ 在房子后面 ” ，是介词短语作状语，一般放在句尾。有时放在句首 是为了表示强调。
例如：a . On the wall there is a map . 墙上有一幅地图。
b . Near the river there is a house . 河边有一所房子。
c . There is a cat under the tree . 树下有一只猫。
2 . Are there any birds in the picture ? 画中有鸟吗 ?
any 形容词，一般用于疑问句和否定句中，后面可接可数名词和不可数名词。例如：
a . Is there any water in the glass ? 杯里有水吗 ? ( water 是不可数名词，句中用 is , 不用 are 。 )
b . Are there any boats in the picture ? 画中有船吗 ?
c . There aren't any flowers in the picture . 画中没有花。
3 . They are at work . 他们在工作。
at work 在 “ 工作中 ” ，介词 at 在此表示状态，这是一个固定词组，在这类词级事， 名词前不用冠词。类似的还有：
at school 在上学，在求学 。 at table 在吃饭，at home在家 ，at play 在玩耍，
例如：a . My English teacher's son is at school . 我们英语老师的孩子在上学。
b . Mary and Tom are at play under the tree . 玛丽和汤姆在树下玩耍。
c . Some workers are at table . 一些工人们在吃饭。
d . My mother is at home . 我妈妈在家。
4 . Young Pioneer 少先队员
该词组是名词词组，有专有名词，所以两词的首字母都要大写。但表示几位少先队员时，不 定冠词或数词不大写。例如：a Young Pioneer 一位少先队员，ten Young Pioneers 十位少先队员，some Young Pioneers 一些少先队员
5 . What about cats ? ＝Are there any cats ? 有没有猫 ?
6 . How many boats are there in the picture ? 画上有几只 ( 多少只 ) 小船 ?
( 1 ) 在由 how many 构成的特殊疑问句中，how many 后常跟可数名词的复数形式。how many 和它后面的复数名词是一个完整的词组，不能分开。例如：
How many boys are there in your class ? 你们班有多少个男孩 ?
How many trees are there in the picture ? 画上有多少棵树 ?
( 2 ) 在回答 how many 构成的特殊疑问句时，根据具体情况有三种回答：
回答：有几个 ” ，用 There are …
回答 “ 只有一个 ” ，用 There is ( only ) one .
回答 “ 没有 ” ，用 There aren't any . 例如：
-How many boats are there in the river ? 河里有几条小船 ?
-There are five . 有五条。
-How many birds are there in the tree ? 树上有几只鸟 ?
-There's only one . 只有一只。
-How many students are there in the classroom ? 教室里有多少学生 ?
-There aren't any . 没有学生。

三、智能显示
【 心中有数 】
单元语法发散思维
A. 需要掌握的名词复数的发音
1 . 名词的复数形式
( 1 ) 以 “ 辅音字母 + y ” 结尾的名词，变 y 为 i，再加 es 。如：baby - babies , family - families ,city - cities 。
( 2 ) 不规则名词的复数形式 ( 需特别记住 )
man - men woman - women , child - children , tooth - teeth（牙） 。
( 3 ) 加 - es 构成的复数形式以及以 ce , se , ze , ( d ) ge 结尾加 - s 构成的复数形式，读［iz］。这样的单词如：buses boxes watches oranges
( 4 ) 以辅音字母 + y 结尾的词，变 y 为 i , 再加 - es , - es 读［ｚ］。例如：
baby →babies family → families
注意：如 y 前是元音字母，则只能加 - s 。例如： day → days play → plays
( 5 ) 还有少数英语单词仍保存了古英语中的复数形式，它们的构成是不规则的，发音也有相的变化。例如： man → men woman → women child → children
注意：house 的复数形式的读音应［′ｈａｕｚｉｚ］，而不是［′ｈａｕｓｉｚ］
B. There be 结构
( 1 ) there be 的否定句一般用 a 或 any 或数字。例如：
There isn't a river in the picture .
There aren't any picture on the wall .
( 2 ) there be 的一般疑问句如有 “ 一些 ” ，一定有用 any 。如：Are there any trees in front of the house ?
( 3 ) there be 的特殊疑问句
1 ) 对 there be 结构中作主语的名词提问，无论是单、复数形式，习惯用法是 What's + 某 地，中间不用 there 。例如：
What's under the desk ? There's a ball under the desk .
What's in the room ? There are many desks in the room .
2 ) 对 there be 结构中表示数量的词提问，习惯用法是：How many + 名词 ( 复数 ) + are there + 某地 ( 某时 ) 。例如：
There is only an apple on the desk .
How many apples are there on the desk ?
There are seven days in a week .
How many days are there in a week ?
