04 There be 句型的用法
【学习目标】
【基础知识】
一.定义:
意思是“有“,表示“人或事物的存在“或“某地有某物“。
e.g.Excuse me. Is there a repair shop near here for MP3?
二、基本结构
1. There is +(单数)可数名词/不可数名词+ 地点状语.
2. There are +复数名词+地点状语.
there 是引导词,在句中不充当任何成分,翻译时也不必译出。
句子的主语是某人或某物,谓语动词 be 要与主语(某人或某物)的数保持一致。
当主语是两个或两个以上的名词时,采取就近原则
There is a bird in the tree. 树上有一只鸟。
There is a teacher and many students in our classroom. 我们教室里有一位老师和许多学
生。
There are two boys and a girl under the tree. 树下有两个男孩,一个女孩。
三、“There be 句型”与“have”的区别:
1. There be 句型和 have 都表示“有“的含义。区别如下:
There be 表示“某处存在某物或某人“;
have 表示“某人拥有某物/某人“,它表示所有、拥有关系。
He has two sons. 他有两个儿子。
There are two men in the office. 办公室里有两个男人。
2. have 表示“包括“、“存在“的含义时,There be 句型与其可互换。
A week has seven days. =There are seven days in a week. 一个星期有七天。
注意:there be have/has 不能连用。
四、含 There be 结构的句型转换
1. There be 句型的否定式
There be 句型的否定式的构成和含有 be 动词的其它句型一样,在 be 加 上 not 即可。
如:
There are some pictures on the wall. →There aren't any pictures on the wall.
There is a bike behind the tree. → There isn't a bike behind the tree.
“在主语前加上不定代词 no , 如:
There is no water in the bottle.瓶子里没有水。
There are no pictures on the wall.墙上没有图画。
There will be no one at home tomorrow morning.明天上午不会有人在家。
注意:也可用“no”来表示。即:no + n.(名词)= not a\an\any + n.(名词)。
no + n.(可数名词单数)= not a\an + n.(可数名词单数);
no + n.(可数名词复数)= not any + n.(可数名词复数);
no + n.(不可数名词)= not any + n.(不可数名词)。
There is an orange in her bag.
There isn’t an orange in her bag.=There is no orange in her bag.
There are some oranges in her bag.
There aren’t any oranges in her bag.=There are no oranges in her bag.
There is some juice in the bottle.
There isn’t any juice in the bottle.=→There is no juice in the bottle.
2. There be 句型的一般疑问句
There be 句型的一般疑问句变化是把 be 动词调整到句首,再在句尾加上问号即可,
但同时要注意:当肯定句中有 some 改为 any(否定变化也一样)。
There is some water on Mars.
Is there any water on Mars? -Yes,there is./No,there isn’t.
There are some fish in the water.
Are there any fish in the water? -Yes,there are./No,there aren’t.
