是用There is my father,mother and I 还是用There are my father,mother and I 为什么?there be不是就近原则吗？

绝对的is there be句型的用法如下，参照第二条
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: 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。
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。
3. 另外,在陈述句中为了强调地点,也可将介词短语提置句首。
如: In the tree there are five birds. 树上有五只鸟。

Use "there is" for one item.(singular nouns) Use "there is" for non-count items.(non-count nouns) Use "there are" for many items.(plural nouns)对单数名词用there is,不可数名词用there is,复数名词用there...
