I just be home for the military training.home是副词,就不能用be了吧?但是

I just come back for the military training.有错误么?just be home be home home是副词为什么后面接不定式? I'll Be Home For Christmas 歌词 FROM是介词吗?如果是介词,那么home做副词时go home中的to就没了,to是介词,而be away from I will be go home for by the two days是病句吗 be home to sb 和be the home to sb为什么不加the就等于be the home of sb 26.Mary _______ be at home.I saw her in the library just now 6.Mary _______ be at home.I saw her in the building just now I have to be home by 10：00pm为什么是be home而不是go home Tiring as it might be,the military training ______ the best be home be away home还是be away from home?home不是副词吗
