刚教到第八单元，教学中有了一些困惑，想与大家一起讨论啊
１．Ｔhere's a football.   There's a volleyball.
      可不可以合并为There are a football and a volleyball.这里的第二个a 能省略吗？另外关于这里是is 还是are ,是不是有个就近原则的语法点啊，我有点遗忘了，请指教啊．
２．There are some bookcases.  There are some books.
     合并时There are some bookcases and books.这里的some 可以省略吧！？

There is a football and a volleyball.There are some books and some bookcases.好象不能省略吧。另外there be 的句型是有个就近原则。

能不能具体说说这个就近原则呢，需要。。。。。

There is a book, a pen and some pencils.There are some pencils, a book and a pen.

There's句型有一个就近原则，不管后面有多少东西，只要There's 后面跟的是a ... .be动词就用is，例如：There's a bed, a desk and a computer in my bedroom.2、There are some bookcases.  There are some books.     合并时There are some bookcases and books.这里的some 可以省略.

以下是引用zhouyanddl在2005-5-19 20:19:49的发言：

There's句型有一个就近原则，不管后面有多少东西，只要There's 后面跟的是a ... .be动词就用is，例如：
There's a bed, a desk and a computer in my bedroom.
2、There are some bookcases.  There are some books.
     合并时There are some bookcases and books.这里的some 可以省略. 好象应该说成靠近be的名词是单数或者不可数名词，不管后面还有什么，be都用单数形式。

同意５楼的意见

There is a football and a volleyball这里第二个“a”可以省略吗？

There is a football and a volleyball这里第二个“a”可以省略吗？不可以省略。

There is a teacher and some students in the sports hall.There are some students and a teacher in the sports hall.根据就近原则，紧挨着be 动词后面的可数名词如果是复数形式，则be 动词用are,单数则用is；紧挨着be 动词后面的如果是不可数名词，be 动词则用is.There is some milk and juice mixed in the bottle.em05][em05][em05]
