Don't, doesn't

In session 15 we are practising the present simple negative.

You will now hear pairs of sentences. The fist sentence is a positive sentence and the second sentence is negative. In the negative sentence you will hear the word don't or doesn't.

I speak English. -- I don't speak English.
I have a computer. -- I don't have a computer.
My colleagues drink coffee. -- My colleagues don't drink coffee.
You often read interesting books. -- You don't often read interesting books.
Our company makes good products. -- Our company doesn't make good products.
This machine works very well. -- This machine doesn't work very well.
This shirt suits you very much. -- This suit doesn't suit you very much.
It costs a lot to stay in hotels. -- It doesn't cost a lot to stay in hotels.
Our line manager reads a lot. -- Our line manager doesn't read a lot.

As you can see we use don't or doesn't to make a sentence negative. Do you know when we use don't and when we use doesn't? No? Then listen to the following text and try to find out:

The best thing about my job is that I meet new people every day. For example one of colleagues is a very interesting person. She buys a newspaper every morning but she doesn't read it. Sometimes she comes to work by car but she always tells me that she doesn't like cars. We work in one office but we don't talk much when when we are at work because we don't get paid for chatting but for working. When the phone rings one of us picks it up but sometimes we don't have enough time to answer it. Both of us speak two languages but we don't have much practice. My colleague also plays chess but I think she doesn't get to do it often.

So, how often have you heard don't and doesn't in this text? It takes some time to learn the present simple negative, doesn't it?
