1、He always gets up early.他一向起得早。
2、Every morning he gets up at seven.他每天早上7点钟起床。
3、It really irritates me when he gets up at noon at weekends.他周末总是中午才起床，真让我恼火。
4、He goes to bed early and gets up early.他睡得早，起得也早。
这两个可以说是固定搭配，get on是指相处，相处得好就是:get on well，well在这里是副词get up的话通常可以加early，late，属于形容词.所以我觉得这种还是要看具体情况.
