Lesson two
among between “在……之间”，区别如下：
(1)between用于表示双方之间的关系，不论双方的数目是多少。 Between+名词复数
The train runs between Beijing and Nanning.火车在北京和南宁两地间运行。 There is a tree between the two houses.这两座房子之间有一棵树。
(2)among后接人或物必须是三个或三个以上，在一群、一组或一个整体中间。如： I saw him among the crowd.我看见他在人群中。
London is among the greatest cities of the world.伦敦是世界上最大的城市之一。 注：在下列情况，between 可用于三者：
(1) 两个以上的人或物用 and 连接时。如： between A, B and C 在 A、B、C 之间 (2) 涉及事物之间的区别或各国之间的关系时。如： the difference between the three of them 他们三者之间的区别 the relations between various countries 各国之间的关系 (3) 表示“由于??合作的结果”时。如：
Between them they landed the fish. 他们协力把鱼拖上了岸。
(4) 在 divide, share 等表示“分享”之类的动词之后，若接一个表示三者或三者以上的复数名词时，用 among 和 between 均可。如：
He divided his money among [between] his five sons. 他把钱分给了 5 个儿子。
习题：
1、Paris is______ the largest cities in the world. 巴黎是世界上最大的城市之一。
2、I found it______ a pile of old books. 我在一堆旧书中找到了它。 3、There was a fight ______ the two boys. 这两个孩子打过一次架。 4、when we talk about the universe,we mean the earth,the sun,the moon and the stars,and the spaces______them.
There be
1
there is /are 表示某个地方存在或有某个不确定的人或物。 该结构一般与介词短语连用，说明范围或地点场所。 There be + 某物 / 某人 + 某地 There be+ sb+sw
1，there is/are 结构中的实际主语是is/are 后面的名词。因此，假如该名词是复数，动词应是are.
There is a flower in the bottle. 瓶里有一朵花。 There is some money in the purse. 钱包里有些钱。 例:There ____ a cup on the table. There ______ some bottles on the table.
There ______ a cup and some bottles on the table. There _______ some bottles and a cup on the table.
2，若句子中有几个并列的主语时,be的形式要与离其最近的一个主语在人称和数上保持一致。
如: There is a boy, a girl and two women in the house. 房子里有一个男孩,一个女孩和两个妇女。 There are ten students and a teacher in the office. 办公室里有十个学生和一个教师。
区别：there be：表示某地有某物，指没有生命的物体有。 例如：There are many books in the schoolbag.
have/has: 表示有生命的人或者动物有。 例如：I have many books. 3，There be 结构的句型转换 否定句
there be的否定式通常在be后加not构成(在口语中be时常与not缩写在一起)。如果句中有some,一般要变成any。如:
There are some children in the picture. →There aren't any children in the picture.
4，一般疑问句及其答语
把be提到there前,首字母大写,句末用问号即可。
2
其肯定答语是Yes, there is / are;否定答语为No, there isn't / aren't。 如:
There is a radio on the desk. Is there a radio on the desk ? Yes, there is. / No, there isn’t. 规则：
is/are要提前, some 变any,其他都不变． 5，There are no students in the classroom. =There are not any students in the classroom.
注意：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。
6，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(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：
