Could you tell me how to begin and end in an E-mail writing? I don't know the words if corrected when I wrote an e-mail.

If I write to a stranger, can I use: Dear Sir/Madam

If I know this person: Dear Mr/Ms surname

My friend: Dear first name

End: Kind regards / Best wishes / All the best

I'm not sure for this kind of words, please help me.

What different between formal and informal e-mail writing of beginning and end?

Adverting I used to an art director in advertising agency. I want to talk about this kind of companies in China. I fond my work because of fantastic and creative. When I intered my company at first, I was expecting for everything. My colleagues looked fashionable and interesting. My boss was kindness in most time. I spent a great deal of time with them and felt cheerful. Furthermore, I learned some useful skills and knowledge from my colleagues. I became more skillful and sociable. Nowadays, I'm freelance working in different advertising agencies and having more free time to do my favorite things.

Vocabulary When I was studying English. My friends usually said that vocabulary is important that you need to memory them first. I bought a book about a particular level in English vocabulary and didn't want to read it anymore. It's so boring if I just read the vocabulary book. I don't like this method even though almost of people recommended it.

Nowadays, I find a useful book, it's called "Oxford Word Skills", I was so delighted because of the content of the book. It's not only a vocabulary book but also having sentences and scene of using. But a few days later, I would forget 40% words when I did revision.

Vocabulary is difficult to remember for me. Do you have any good methods to remember them?
