Step1. Greet the class. Good morning/afternoon, Class. How’s the weather today? Step2. Lead in
1.Look and say: 朗读并观察下列句子:引出There be 句型
1.There is a picture on the wall.
2.There is a bag behind the chair.
3.There is an English book in the desk.
4.There are four pictures on the wall.
5.There are some shoes under the bed.
6.There are two boys in front of the house.
让学生初步感知 There be 句型并找出句型规律。
2.Present and explain:
1)Basic structure:There be + 某人或某物+ 介词短语。
2) Meaning :“There be ”conveys the meaning:“某处有某人/某物”。
3) Analysis : there 是引导词,无词义;
be是谓语动词;
“某人或某物”是句子的主语;
介词短语多是句子的状语;
Step3. 呈现There be句型考点各种句式的变化
考点一:就近原则
be动词单复数形式要跟there be之后的第一个主语保持一致,如果第一个主语是单数或不可数名词用is,如果第一个主语是复数则用are。
请使用There be--- 描述下图(见课件)
教师先引导学生运用此句型结构造句,然后让学生两人一组进行操练,相互检查,然后让一部分学生把练习成果和大家分享
There is a cat and two birds in front of the house.
There are two birds and a cat in front of the house.
考点二 : There be--- 的一般疑问句
规则:is/are要提前, some 变any,其他都不变.
考点三: There be 句型的否定形式
规则:Be动词后面加not, some 变any There be否定句型中的not any与no可以互换。not any强调一个都没有。
考点四: There be 句型的特殊疑问句形式
1.对主语提问:
当主语是人的时候,则用who 引导,当主语是物的时候,则用what 引导。
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 is (回答时却要根据实际情况来决定)。
如:
There are lots of cars over there.
→What's over there?
There is a little girl in the room.
→Who is in the room?
2.对地点状语提问:则用where 引导 如:There is a computer on the desk. → Where is the computer?
● There are four children on the playground. →Where are the four children?
3.对数量提问:一般有两种句型结构:
●How many+复数名词+are there+介词短语?
● How much+不可数名词+is there+介词短语?
考点五: There be 句型和 have / has
there be 句型表达的是“在某个地方存在某人、某物等”,have / has 则表示“某人拥有某物”
活动一:大声朗读:读下列句子并注意其结构。
表示“有”,分两种。
there be没生命,have,has有生命。 桌子板凳没生命,自然是用there be.
_?°±è????????_别忘记,is、are把be替。 小猫小狗有生命,have, has不离弃。
只有单三用has,其他都是用have.
There is a bag on the desk .
There are some books in the bag .
They have some books at home .
I have a red bike .
We have a big house .
He has a black car .
My brother has a new ruler .
考点六 : there be句型有时态的变化
1. there be 句型的一般过去时There was/ were+某物/某人+其他。
2. there be句型的一般将来时(重中之重)There will be +sb/sth +其他
There is (are) going to be +sb/sth +其他
如:There will be a party on Monday.There is going to be a meeting this afternoon.
will be = is/are going to be
活动二:Can you use “be” easily? 比一比,谁最快。(见课件)
考点七: There be 句型的其他结构
There be+sb.+doing sth.+地点/时间 表示:有某人或某物正在做某事
For example:
树上有一只鸟正在唱歌。 There is a bird singing in the tree.
街上有两个男孩正在奔跑。There are two boys running in the street
活动三:请根据下面的描述画一幅画 (小组活动并展示)让学生把自己认为写得好的一个句子和大家分享
This is a nice picture. There's a river in it. On the river there's a boat. There're some children in the boat. They're boating. Near the river there's a tall tree. There're two birds singing in the tree. There're two cats climbing up the tree. They want to catch the birds. I like the picture very much.
Step6. 课堂小结:
There be句型有特点,主语跟在be后边。
单数主语用is,复数用are记心间,
多个主语并列时,be随身边主语变。
变否定,很简单,be后要把not添。
变问句也不难,把be提到there前。
肯定句中用 some,否定疑问any 换。
