1、等于为了……in order to so that so as to for 但是几个在用法上有些区别 比如 I got up early this morning in order to catch the first bus.只能用在句中 I got up early this morning so that catch the first bus.也只能用在句中 而so as to catch the first bus ,I got up early this morning.可以用在句首 同时I got up early this morning so as to catch the first bus .也可以用在句中 I got up early this morning to catch the first bus. to catch当不定式,表目的 I got up early this morning for catching the first bus. for当表目的的介词。

2、后面动词应为现在分词。
