To make the grammar correct and english make sense I have not always used the words provided. 1, He goes to school. 2, He went to school. 3, He has gone to school. 4,he went to school rather than coming home. 5,Rather than coming home, he went to school. You have some tenses (past, present, future) mixed up, hope this helps.

Hi Weiyang Luo, 1,What he does is (goes/go) to school. ==> What does he do ? -> He goes to school. 2,What he did was(went/go)to school. ==> What did he do (yesterday) ? -> He went to school. 3,What he has done is(gone/go)to school. ==> What has he (always) done ? -> He has gone to school. 4,he went to school rather than(came/come)home. ==> What did he do ? -> He went to school rather than coming home. 5,Rather than(came/come)home,he went to school. ==> What did he do ? -> Rather than coming home, he went to school. Have a nice time. Georg
