教学课题: there be 结构
一、教学目标:
1、掌握There be 结构所表达的意义。
2. 掌握There be 结构的一般现在时和一般过去时基本句式。
3. 掌握There be 结构的回答方式。
二、重点难点
there be 句型的肯定式、否定式一般疑问句及其回答方式。 There be句型和
havehas的区别
三、教学方法:
讲授法、分组讨论法、任务型教学法、多媒体教学
四、教学过程
(一)、there be构成
There be ...句型,表示的.是 “某地或某时有某人或某物”,其结构为There be(is,are,was, were )+某物 / 某人 + 某地 / 某时。
二、There be 结构的一般现在时和一般过去时各种句式。
(1)肯定式
There is a supermarket on that road.
在那条路上有一个超市。
There was a supermarket on that road last year.
去年在那条路上有一个超市。
There are many people here on vacation.
有很多人在这里度假。
There were many people here on vacation last summer. 去年夏季有很多人在这里度假。
(2)否定式
There be句型否定句式的构成和含有be动词的其它句型一样,在be后加上“not”。例如:
There isn`t a supermarket on that road.
在那条路上没有超市。
There wasn`t a supermarket on that road last year. 去年在那条路上没有超市。
There aren`t many people here on vacation.
没有很多人在这里度假。
There weren`t many people here on vacation last summer. 去年夏季没有很多人在这里度假。
(3)一般疑问句:There be结构的一般疑问句变化只需把be动词移到句首,再在句尾加上问号即可。例如:Is there a supermarket on that road ?
那条路上有超市吗 ?
Are there many people here on vacation.?
有很多人在这里度假吗?
Was there a supermarket on that road last year ? 去年在那条路上有超市吗 ?
Were there many people here on vacation last summer? 有很多人去年夏天在这里度假吗?
三、注意事项:
1. There be句型中be动词的形式要和其后的主语在人称和数上保持一致。
如果句子的主语是单数的可数名词,或是不可数名词,be动词用“is”“was”。例如:
There is a basketball in the box.
箱子里面有一个篮球。
There is a little milk in the glass.
瓶子里面有一点牛奶。
如果句子的主语是复数名词,be动词就用“are” “were”。例如:
There are many birds in the tree.
树上有很多小鸟。
There were many people in the street yesterday.昨天街道上有很多人。
如果有两个或两个以上的名词作主语,be动词要和最靠近它的那个主语在数上保持一致,也就是我们常说的 “就
近原则”。例如:
There is an orange and some bananas in the basket.
篮子里面有一个桔子和一些香蕉。
There are some bananas and an orange in the basket.
篮子里面有一些香蕉和一个桔子。
2. There与be中间可插入一些表推测的情态动词、表时态的短语和一些动词短语 (如和将来时be going to will、现在完成时 havehas + pp. 、used to结构等连用,注意其构成形式,这一内容在我们日常练习中经常出现错误,是一难点,也是历年中考试题中的一个考点.)。例如:
There must be a pen in the box.
There happened to be some money in my pocket. There is going to be a meeting tonight.
There has been a big tree on the top of the hill.
There used to be a church across from the bank.
3. There be句型和havehas的区别:
There be句型表示 “存在有”, havehas表示 “拥有” “所有”,两者不能同时使用.例如:
桌子上有三本书. There are three books on the desk. 我有三本书. I have three books.
