My common grammar mistakes + vocabulary link

Comma use:
"Jack who was helping me to...."
Correction:
"Jack, who was helping me to..."

Use a comma to set off parenthetical elements, as in "The Founders Bridge, which spans the Connecticut River, is falling down." By "parenthetical element," we mean a part of a sentence that can be removed without changing the essential meaning of that sentence. The parenthetical element is sometimes called "added information." This is the most difficult rule in punctuation because it is sometimes unclear what is "added" or "parenthetical" and what is essential to the meaning of a sentence.

Example:

Jack, that is from scotland, eats food.

Francisco, who eats people, ate his sister.

Section 2 task 5

Yesterday I was at a soccer match in your stadium, everything was fine, people watching the game and the players playing. But suddenly I sas how a player took the ball in his hands and threw it to the floor, this is unacceptable how didn't your referee see that. It's also called football and the foot part isn't coincidence. It isn't fair, players can't just broke rules.
I have a few suggestions so this doesn't happen again, you can train your referees so they don't miss anything, you can select th referees you hire or you could have more people helping the referee.
Hope you take my suggestions seriously so this doesn't happen again in the future.

Best Surprise

A few weeks ago I organized a party for my friend, Julio, it was really messy at the beginnig.
Jack, who was helping me to organize the party, had the idea, he brought me into the "project" with two more friends.
We decided to do this because he always does this kind of things to us so we thought it would be nice to return the favour.
First we went to buy all the stuf for his party, we left Diego distracting him so he didn't caught us, just in case.
We finished buying but while preparing the stuff for the party, someone called Jack and told him he had to go back to scotland. It was a problem because he was Julio's best friend.
While we convinced Jack to stay until the party started, they called him again and his house in scotland had burnt so he would live a couple months more in chile, we were so happy he was staying but sad for his house.
Finally Julio entered and we surprised him, he was very happy, but he said he was expecting it.

Dear Diego:
I heard you want to become a tv presenter, I will give you some tips so you can do this.
You should find a plaec to work as a tv presenter, you will have to be  accepted to work there. You will need to speak very clearly, be self-confident and have the ability to speak without being nervous or at least so that it isn't noticeable.
It might be difficult, because not everyone can do it, it's an important part of being a tv presenter.
Good Luck

Section 2, task 2

The Boring Center
Yesterday I went to your new leisure center and I think it's not working very well, people are not having fun.
The service is really bad, a few games aren't fun you need better things to do and better people. Without a friendly staff you won't get so far.
I have a few suggestions for you, so your leisure center won' be that bad as it is now.
You should train your staff or get new people, friendly people. Also you should get fun stuff to do because it gets really boring in there.
Also if you make a nice place there,maybe a beautiful place it would be great, it would be attractive to a person.
Hope you take my suggestions seriously.

My Visit to Mexico
One year ago, I visited a place near cancun in Mexico, it is called "Riviera Maya"
When I arrived it was really hot, it was winter and at least 35ºC.
First we went to the hotel and just left our stuff, everything was so full of life, if you looked to one of the million plants you would see a different animal.
Also there was a beach and if you looked in a bush or something like that you would see more animals.
There I met some kids, they were from Mexico, they were just walking by there, but we played, soon they had to leave so I didn't see them anymore.
I recommend the place, it's fun and something different from what you see everyday.
I would go back to this place if I had the opportunity, it was a really good experience that I'd like to have again.

Referee mistake

Yesterday I was at a rugby match in a stadium of Viña del Mar, when I realised that one player should've got a penalty but he didn't get anything.
This shouldn't happen because you let a team broke a rule and it's unfair.
You should prevent this from happening again, you could get a training for your referees so they don't miss anything the players do. This would make the game fair for both teams.
Another thing you could do would be to choose the referees you hire and make sure they don't make this mistakes that can give an advantage to one team and a disadvantage to the other one.
Hope you read this and do something so we can watch fair games.
