you must be home at half past ten.
里面的be是个什么意思,为什么不用back
must be不是表推测“一定”嘛
不要大量复制

1.must在此句中是必须的意思,表示命令.be home在家,回家.be 表状态.也可用be at home或be back home.不能说must back home.因为must后接动词原形,back是介词.
2.must be+名/形/介词短语表示推测,是一定是的意思.例如：
You must be a teacher.你一定是个老师.
It must be true.这件事一定是真的.
She must be at school.她一定在学校.
3.must be+doing一定在做某事.例如：
He must be watching TV.他一定在看电视.
希望对你有用!
