There be结构中的be动词的确定：
1. there be 结构中的谓语动词be在人称和数上应与其后的主语保持一致。主语是不可数名词或单数可数名词时用is，是复数时用are。如：

   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。

考点名称：主谓一致

• 英语中的一致主要包括主语和谓语在人称和数上的一致、时态一致、名词和其代词的一致。
  主语和谓语保持一致叫主谓一致，即谓语动词的形式必须随着主语单、复数形式的变化而变化。

• 主谓一致原则:
  1、语法上的一致
  所谓语法一致原则，即主语和谓语的语法形式在人称和数上取得一致。
  谓语的单、复数形式依据主语的单、复数形式而定：主语为复数，谓语动词用复数；主语为单数或者是不可数名词，谓语动词用单数。
