## Exercise III

### Вставьте необходимые предлоги.

Dear Mr. Roony,
I'm writing in reply your advertisement for secretaries to work your central offices. I heard you from a friend of mine, Ninez Peres, who worked you a few years ago as a sales manager.
I would be interested applying a full-time position. I'm experienced secretarial work. I suppose I'm quite skilled word-processing. I also worked documents: compiled, sent, changed.
I enclose a reference my previous employer and copies my certificates. I would be pleased to come for an interview any time which is convenient to you.
I look forward to hearing you.
