in order to / so as to
Note that, as an alternative to to + infinitive, we might
use in order to, or so as to, to express individual
purpose when we want to be more formal or explicit
about the reason for doing something. All of these structures answer
the question: Why
?. Compare the following:
- I went to bed early in order to get enough sleep before
- After four weeks of exams, I went to the seaside to rest.
- After twenty days of exams, I went to the seaside for a rest.
- After all those exams, I went to the seaside so as to have
a good rest.
The in order to and so as to structures are particularly
useful with stative verbs such as be, have, know, appear,
and before negative inifinitives:
- So as not to appear foolish, I learnt all I could about
the company before going for the interview.
- I'm going to move to the city centre in order to be near
where I work.
- In order not to have to commute, she bought a flat in
the town centre.
- In order to know more about him, she studied his movements
