My parents are at home now

at home整体是什么词性呀？什么意思？我看了语法说be动词表示存在和状态。at prep表示空间，home vt.表示把什么送回家，这样now adv修饰home
可是home vt 是及物动词，他后面没有宾语呀。是不是及物动词后面可以没有宾语呀？
我才词典at home中的home是vt

there are five people at my home,they are my parents and i 还是they are my parents and me Neither of my parents are at home. 这句话对吗？ My parents How are you parents? My parents and I are both at home. 次句为什么用both? my parents work hard 英语小短文 《My parents》 My relation with my parents is bad 一道高中英语选择题(The parents are) They are scientists,just[ ] their parents were.
