英语翻译A snake which is in my shou.是个什么句 which 可不可以省?

不对!have 的主语一般是人,there be 句型一般表示客观存在的事物
所以应该是：There is a snake in my shoe.
接问题补充：
A snake which is in my shou.不应该算一个句子,这是一个带有定语从句的单词,
可以译为：那个在我鞋里的蛇,它可以做一个句子的主语或宾语,但不是一个完整的句子.
而且有从句修饰的词或短语的冠词要用the,不可以用a
如果去了which,这就是：A snake is in my shoe.这也是可以的
总之：我认为：There is a snake in my shoe.和A snake is in my shoe.都是对的,但A snake which is in my shoe.怎么都是不对的.
