Level 5 Unit 4 -
So, so that, & so as

Select the correct answer from the choices given.
SO
Often cause and effect.
The first sentence is the action and the second is the response.
The job's finished SO let's go to the pub.
I didn't like the beginning of the film SO I left the cinema.
I need some money SO I'm looking for an ATM.

SO THAT
To make something possible (or impossible). To explain a consequence.
I had a little door made SO THAT the cat can get out.
I use a wifi conection for the internet SO THAT I can use my computer anywhere in the house.
They chained the prisoner SO THAT he couldn't escape.
The earth turns on its axis SO THAT to us it seems to move around the earth.


NB.Often, we shorten phrases in conversation. Thus, we may use “so” when we mean “so that.” This is all right as long as the punctuation identifies whether you are using “so” as a conjunction or as a shortened form of “so that.”
For example the last sentence would have a comma:
The earth turns on its axis SO, to us it seems to move around the earth.

When it is personal, it can be adapted
He got an international licence SO THAT he could drive in China.

SO AS
In order to. There is an idea of purpose
Similar to SO THAT but uses an infinitive:
He got an international licence SO AS to drive in China.
These days divers use Nitrox, a special gas mixture, SO AS to make longer dives.

EXPRESSION:
The expression "So what!" means "I don't care.", "That's not my concern." It is usually impolite.
