Lucy had to stay home yesterday because of th heavy rain.是个句

Lucy had to stay home yesterday because of the heavy rain.
因为昨天的大雨,露西不得不呆在家里.
是个句子.
用不用at都一样.
因为home既可以做副词用,也可以做名词用.
如果是stay at home,那这个home就是名词,所以前面要用介词at
如果是stay home,这个home就是个副词了,所以前面不加at也可以.
比如说：词组 go home 和go here,go there是一样的.
因为都是副词,所以不是go to home.
