teach in/at a school

[Winwin2011]

1. I teach in/at a school?
2. I study in/at a primary school/university?
3. I work in/at a computer company?

Should I use "in" or 'at" in the above sentences?

Thanks for your help?

It's not as simple as that.

1. A teacher would say 'I teach at a school in London'.

2. A young child would say 'I go to (a primary) school near our house'.

A university student would say 'I'm studying at (Manchester) University'.

3. An employee would say 'I work for a computer company'.

Thanks.

1. Do you mean " I teach in a school" is incorrect?
2. Can I say "My son is studying at /in ABC primary school" in a letter?
3. Can I say "I am working at/in a computer company" in a letter?

Can anybody further explain?

Thanks in advance

I think that's just the ways English speakers speak, "teach at a school", "study at a university", "work for a company".
If there is some explain, I would like to know it.
Thank you very much!

Thanks.

1. Do you mean " I teach in a school" is incorrect? It's grammatically correct but not colloquial.

2. Can I say "My son is studying at /in ABC primary school" in a letter? We'd say 'My son goes to ABC primary school, not is studying at/in ABC primary school.

3. Can I say "I am working at/in a computer company" in a letter? You can say whatever you want in a letter. Most native speakers would say 'I am working for a computer company'.
