Purpose Connectors: To, In Order To, So That
B1-B2 Level
English Exercises is teacher-led by Charlie. About the teacher · How content is made
So that is different because it is followed by a full clause (subject + verb): "She left early so that she could catch the train." "So that" is especially useful when the subject changes: "I wrote it down so that I wouldn't forget." So as to is a formal alternative to "in order to": "She whispered so as not to wake the baby." The negative forms are important: "in order not to" and "so as not to" (not "to not" or "for not to"): "He left quietly in order not to disturb anyone." These purpose connectors are commonly tested in Cambridge Preliminary and First examinations at B1-B2 level.
Quick Rule
to / in order to / so as to + base verb | so that + subject + verb
- 1.She took a taxi to arrive on time for the interview. (simple purpose — to)
- 2.He studied hard in order to pass the final exam. (formal purpose)
- 3.I turned off my phone so that nobody would disturb me. (purpose with different subject)
- 4.We left early so as not to get stuck in traffic. (negative purpose — formal)
- 5.She didn't tell anyone in order not to cause unnecessary worry. (negative purpose)
