19-5 Expressing purpose : Using so that.

-In order to and So that express purpose.
Ex:
-I go to school in order to study.
-I sleep in order to getting healthier.

-So that + can/could = in order to. So that is often used instead of in order to when the idea of ability is being expressed. can and could are used in adverd clause, but can is used for present and future, could is another.
( The word "that" is often cut, especially in speaking.)
Ex:
-I'm going to call my dad so that I can ask for money.
-I exercised so that I could be strong.


-So that + will/would or simple present = to make sure something.
(Would is used in past sentences)
Ex:
-I will go to school so that I will not miss the new class.
-I called my friend few seconds ago so that I would understand my homework.
-I will set my alarm so that I don't wake up late.


Note : - In oder that= so that ( but in oder that is less commomly used)
           - We can change can/could to may/might in some cases, but less commonly.
