Hi Jasmina, I've made some minor edits, but otherwise very good. Good luck!

Dear J....,

Thank you for your time last Friday, It is exciting that the project is progressing.
Please find attached my CV and below my statement to apply for the position of Community Organiser:

Since 2012, my background has been characterised by my dedication to contribute in charities that aim to help residents in the borough of Southwark. 

Currently, I spend time with families to resolve issues in different fields such as, Housing, Welfare and NHS. It has involved performing a variety of office roles and interpret for Spanish speaking residents, whether attending authorities offices, the GP or Hospitals to follow treatments. 

In my last job as Action Researcher for the Childhood Obesity project, I gained extensive experience dealing with parents and I enjoyed developing relationships with community leaders in order to organise venues for the listening groups.

In 2014, my role as Information and Support adviser consisted of being the first contact for residents who wanted to do volunteering work. This job required database input, searching for opportunities, making calls to arrange interviews and monitoring volunteers to help them with their progress. 

In addition, I took a Kitchen Assistant training course (equivalent from Spain) that qualified me to work in restaurants and hotels. The course included Health and Safety in the workplace and Food Management in a professional setting. When I arrived to in the UK in 2008, I worked in a Burger King for two years, where I started in the kitchen whilst learning English before gaining promotion within the company. Alongside this, I worked in a Peruvian restaurant during the weekends.

I am confident speaking both languages English and Spanish,  which allows me to facilitate working with different cultures and backgrounds. I believe that I can actively contribute with families because I am usually described as an easy going person, who is able to assimilate with a wide range of people.
I would describe myself as tolerant, patient, dedicated, kind and at the same time, proactive. I am passionate within the community, organising tasks related  to healthy living and I consider that this position would bring me a huge opportunity to progress and achieve my next goals.

Thank you for your consideration. 

I look forward to meeting with you to discuss my application further.

Yours sincerely,

Hi Denis, If the opposing team scores then the goalkeeper concedes a goal.

1) In the UK and Australia colloquially I know this feeling as "having pins and needles". However, saying your leg is asleep will be perfectly understood 2) Correct cramp would be used in this situation. e.g. present tense: "I've got/I have a cramp in my leg". past: "I had/got a cramp in my leg" or "my leg cramped up"...

Human or Super Human

Hi, my name is Juan, and i am a Runner. In my opinion, running is the best exercise than the that people can do, because it is cheap and there is no need a for special equipment, only a couple pair of sport shoes and some colorful clothes. The Last saturday, my team and I was were in a competition. We ran a half marathon in the desert. there It was hot and sunny. In that race, there was four mode options(? unfamiliar with running terms but this sounds more natural): 21 kilometers, 55 kilometers, 106 kilometers, and 150 kilometers. A half marathon is a 21 kilometers competition. But my friend, Eliezer, he ran 150 kilometers! He ran for almost 23 hours, without sleep and he was a the winner! Is it the For this reason because we told him he is Super Human. I am so proud about of him. The man in the picture is my friend, Eliezer. 

Thank you for reading.

You are correct. It should always be there are when followed by plural nouns, there is no exception i know of. However, in informal speech it will generally go unnoticed (the speaker may not even be aware). I am often probably guilty of this myself!
