Structures with so
So is often used as a general purpose connector and comes at the beginning of sentences.
- So, when do you want to move in?
- So, what have you decided?
- So, what do you think we should do next?
This structure is used to show purpose.
- Speak loudly so that we can hear you.
- Work hard so that you will pass.
- We eat so that we may live.
- He hid himself in the bush so that he would not be caught.
So that may also indicate the result.
- He remained still so that people thought that he had died. (= Because he remained still people thought that he had died.)
- She was standing behind the door so that I couldn’t see her face. (= As she was standing behind the door, I couldn’t see her face.)
- He lowered his voice so that no one would hear.
- I will get a map so that we won’t get lost.
For emphatic use
In an informal style, so is used for emphasizing a quality, feeling or amount. So means the same as very in this case. This structure is like an exclamation.
- I am so happy. (How happy I am!)
- She was so angry. (How angry she was!)
- I’m so glad that you still remember my name.
- Thank you so much for coming.
This structure shows the result. We cannot use a that-clause after very. Instead, we use so…that.
- I was so excited that I couldn’t sleep.
- She was so tired that she couldn’t walk.
- The tea was so hot that I couldn’t drink it.
- The weather was so hot that we didn’t go out.
Note that the same idea can be expressed using the structure too…to.
- I was too excited to sleep.
- She was too tired to walk.
- The tea was too hot to drink.
- The weather was too hot to go out.
