在某人家中英文

At one's house

at home 和 in one’s home 都意为“在家”。如果用at ,在 home 前不能用其他词语；如果用in ,在home 前必须用相应的形容词性物主代词。eg : People will have robots in their home.They’ll study at home on computer.

at one's home.home这里不是物质名词，偏抽象名词，所以用at.

at sb`s eg. at Tom`s

In someone's family

in somebody family.

at my aunt's home 表示此时你就在阿姨家中，现在式；in my aunt's home表示曾经你在阿姨家中，过去式。
