Begin your letter as follows: Dear Sir / Madam
You should write at least 150 words. You should spend about 20 minutes on this task.

Dear Sir or madam,
I have recently read about your organization in the local newspaper. In my opinion, you are doing a great job and you are giving a great opportunity to people who have a desire to help people living in abject poverty.
I have just graduated from the Pedagogical University and got a degree in English philology.
My late aunt left me fifteen thousand dollars in her will and that' why as at the time being I do not have to work and in memory of my aunt I decided to share my knowledge and to teach English on voluntary basis to people who can't afford it .
Moreover I also speak French fluently and while doing my degree I had a practice in school where I taught both English and French.
It was mentioned in the article of your newspaper that the work of Cultural Expeditions covers countries in Africa. If it is possible I would like to work in Nigeria for one year from September 15th.
I am sending my CV where you can found all information about my education and references.
If you have any questions you can get in touch with me via my email or phone number written in CV.
I am looking for your reply,
Yours sincerely,
