leave for home 和 leave home 都对但意思不一样（回家,离家）
我觉得应该事leave的时态,如果说 we leave for home tomorrow.就可以.但原句觉得没完.
应该说：we are leaving for home/ we will leave for home/ we left for home 等等.
上面说的不对：
1.home前当然可以加介词：at home
2.home当然可以是名词：home sweet home.my home is far away.
3.如果去掉for,句子还是不对的：we leave home.X.同样感觉句子没完.
