复习内容:熟记there be 句型的各种句子形式及运用。
教学步骤:Step 1
(一)、定义: There be 结构主要用以表达 “某地有某人(某物)”。其基本句型为“There be + 某物或某人(主语) + 某地”。
(二)、be动词的选择: There be 结构中的谓语动词be(is / are)在人称和数上应与其后的主语保持一致。主语是不可数名词或单数可数名词用is ;主语是复数时用are。
(三)、具体结构:(1) There is + 单数可数名词/不可数名词+ 地点状语.
E.g. There is a pear in the basket.
E.g. There are 3 pencils in the box. 盒子里有三只铅笔。
巧计语法:
“有”字放前面,有“啥”放中间;
时间地点放后面;单数is, 复数are
注意be的两变化。
(四)句型变化:
(1)、否定句:there be的否定式通常在be后加not。
E.g. There is a ball under the tree. 树下有一个球。
There isn't a ball under the tree.
E.g. There are six boys in the classroom。教室里有六个男孩。
There aren't six boys in the classroom.
(2)、一般疑问句及其答语:
1、一般疑问句:把be动词提前,首字母大写,句末用问号即可。
2、回答时,“用什么问,就用什么答”,用Is / Are there来问,就用there is / are来回答。
肯定回答:Yes, there is / are.
否定回答:No, there isn't / aren't.
E.g. 1、There are eight birds on the sofa. →
Are there eight birds on the sofa
Yes, there are. / No, there aren't.
. 2、There is a cup on the table . →
Is there a cup on the table .
Yes, there is. / No, there isn't.
课堂练习:1. There is a student and a teacher in the classroom .
否定句
一般疑问句
否定回答
(五)、some和any在“there be”句型中的用法:
1 ). some 一些(some用于肯定句)
2 ). any 一些(any用于否定句和一般疑问句)
注意:There be句型在变成否定句或一般疑问句时,要注意把句中的some变成any。
E.g.1、There is some milk in the glass.→
There isn't any milk in the glass.(否定句)
Is there any milk in the glass?(一般疑问句)
2、There are some women on the playground. →
There aren't any women on the playground. . (否定句)
Are there any women on the playground?(一般疑问句)
课堂练习:1. -- Are there _____ banks behind the park
-- No, there are _____ banks behind the park.
A. some, not B. some, any C. any, not D. any, no
2.There is a book in the bag.(变为否定句)
(六)、就近原则:
若句子中be动词后有两个或两个以上并列的名词作主语时, be动词的形式要与离其最近的一个主语在人称和数上保持一致。
E.g. 1.There is a box, two pens and some erasers on the desk.
书桌上有一个盒子、两支钢笔和一些橡皮擦。
2.There are two boxes, a pencil and some erasers on the desk.
书桌上有两个盒子、一支铅笔和一些橡皮擦。
3.There some erasers ,two boxes and a pencil on the desk.
书桌上有一些橡皮檫、两个盒子和一支铅笔。
课堂练习:There milk and eggs on the table .在桌子上有牛奶和鸡蛋。
There eggs and milk on the table.
(七)、“there be” 和 “have”的区别
There be结构和have都表示“有”,但用法不同。
there be结构强调客观存在,表示“某处有(存在)某人/物”。
have强调所属关系,表示主语“拥有”。
There be 句型表示“存在”关系,have表示“所属”关系,两者不能混在一个句子中。
Eg:There is a watch under the tree.(表示某处有(存在)某物)
I have a watch .我有一块手表。(表示某人拥有某物)
(八)、there be 句型的一般将来时态有两种形式:
(1)a.there is going to be 指已计划或打算好的,“be”不变化,但is会随着人称,数和时态的变化而变化。此句可理解为:Something is going to be there.
(2) there will be 指“临时决定的” be 是不变化的。此句可理解为:Something will be there.
(3) There is/are going to be 或There will be 其否定形式是在is /are/will后加否定词not; 一般疑问句是直接把is/are/will提到句子开头。
a. 肯定回答:Yes,there is/are或Yes,there will。
b. 否定回答:No, there isn’t/aren’t.或No,there won’t.
Eg: a). There is going to be a sheep on the farm.→
Is there going to be a sheep on the farm
There is not going to be a sheep on the farm.
b). There will be an egg on the plate.→
Will there be an egg on the plate
There will not be an egg on the plate.
(九)、含有there be结构的反意疑问句 如果陈述部分为there be结构时,则疑问部分用be(not)there或will not there 。例如: a).There is not much news,is there?b). There will be a new hospital nearby, won’t there 这 附近要建一家新医院,是吗?
(十)、 there be句型的特殊疑问句形式有以下三种变化:
对主语提问:
a). 当主语是人时,用“Who’s+介词短语 ”
b). 当主语是物时,用“What’s + 介词短语 ”.注意:无论原句的主语是单数还是"复数",对之提问时一般都用be的"单数"形式(回答时却要根据实际情况来决定).
对地点状语提问:提问地点当然用“Where is / are+主语 ”
对数量提问:一般有两种句型结构:
a). How many+复数名词+are there+介词短语
b). How much+不可数名词+is there+介词短语
Eg: How many books are there in the bag
How much bread is there in your bowl
最后总结巧计语法:
There be结构表存在,记清be有四时态,肯疑否反特明白,三词两句可互换,就近原则动名带,have所属是关键。
