go是不及物動詞,後面跟名詞則要+to 不過因為home是副詞，所以不用+to 類似的還有arrive,如果後面是名詞的話要加at/in 如果後面是副詞,像home,here,there則什麼都不加,比如說: I often go to school by bike. I go home at 5 o"clock. I arrived in London yesterday. I arrived here just now. go是不及物動詞,後面跟名詞則要+to 不過因為home是副詞，所以不用+to 類似的還有arrive,如果後面是名詞的話要加at/in 如果後面是副詞,像home,here,there則什麼都不加,比如說: I often go to school by bike. I go home at 5 o"clock.

I arrived in London yesterday. I arrived here just now. I arrived here just now.go to school =泛指去某地；to school 是介詞短語，做地點狀語go home =泛指回家；此處home是地點副詞；

1.它們之間的區別在於：介詞短語做地點狀語與副詞作地點狀語的區別。

2.但是home 有名詞詞性；upstairs沒有名詞的詞性。副詞前面是不能用the的。
