Hi - I understood everything, corrections are mostly verb agreement and tenses and a more natural way of speaking. Hope this helps.

A letter to the manager of the restaurant

Hello, I'm doing some exercises to practice my writing. My text is based in this exercise:

You are a member of an organisation which meets regularly at a particular restaurant. The most recent meal you had there was not satisfactory. Write a letter to the manager of the restaurant.
• introduce yourself and explain why you are writing
• explain what was wrong with the food and the service
• suggest what he/she should do to ensure that you and your group return to the restaurant

--------------------------------------------------------------------------------------------------------------------

Mr. Manager,

I am a member of a business organization and often our group meets in your restaurant to talk about job.
I am writing this letter because in the last time we had gone in went to your restaurant to the for lunch the service was not satisfactory and our important guests had got or received a really bad impression about it.

One of our guests asked to the waiter for a suggestion of a typical food from the region and the waiter was rude and said that he could not help her with the choice. Our guest ignored this situation and ordered rice, tomatoes and beef. When she was eating she found strand of hair in the rice and the beef was raw. So, unhappy, she called the waiter and reported the situation. The worst thing was that the waiter did not apologized and thirty minutes after she complained he brought another meal with a bad face.

We meet in your restaurant regularly because it is closer to our organization and because the restaurant is known to receive serve great entrepreneurs. You should advise your waiters and waitresses to be more polite with the coustuomers. The other important thing important is hygiene in the kitchen, your cooks should use disposable caps to avoid strands of hair in the food.

This was our first problem with the restaurant. If you improve correct the faults and respond to this letter show us a position about this, we will probably return to the restaurant. Otherwise, we will look for another one.

Best Regards,

Freitas.

An unexpected call

It was three o’clock in the morning when the phone rang. Firstly (or At first), I believed it was the alarm clock but when I had totally woken up I realised it had been the mobile phone that I had put on the old, black table of in the dining room last night. I run ran towards the table where I had left it, but it had just stopped.
Obviously, I didn’t know the number that I could see (saw) on the lighted screen, because neither my family nor my friends would have had phoned me at three ours in the morning unless it had been were a very important or urgent issue.
As soon as I took de the phone, it rang another time but before I could answer it stopped. I started to get worried because it was the first time that had happened to myself me, something like that.
Suddenly, I remembered that last day yesterday I had asked the doorman of my house to warm myself at three our  o'clock, but it was for 3 p.m. and not 3 a.m.
Finally, I understood the mistake and became went back to the bed more relaxed.

Some errors but no trouble understanding what you meant. Hope this helps.

Can you answer these questions?

wich are correct? he is at the university or he is at university, she is at the school or she is at school, can you tell me the reasons for your answers?

how do you call a school teacher? teacher or mister or both


thanks.

In the US 
he is at the university, but not he is at university

but he is at/in college would work as a general status, a particular college would be at the college

same for school.

in the US we would not say "Teacher Jones" we would say Miss Jones or Mister Jones.
