Writing about tennis My favorite sport is tennis. When I was a child, I used to watch tennis matches at tv. However, it was not until two years ago when I started to play it. My mother told me that I needed to do some sport and, as I live near to a tennis court, I decided to go to tennis classes. At first it was really difficult. I’ve never thought that tennis was such a technical sport. You need to learn how to hit the ball, how to serve and how to move yourserlve in the court. When you start is also boring, because you can’t hit a ball twice. Last year I decided to continue with the classes, because I think that the teacher was good and the class mates were friendly. I went twice a week and each class last one hour. The only problem is that when it’s raining we can’t play and, this year, due to the rain I have missed a lot of classes. Although I’m not very good at tennis, I like to play it. So now, in summer, I don’t have tennis classes, but I’m trying to play tennis at least once a week.

Walking along ‘la ruta del Cares’ Last weekend I went to my mother’s village with my family and my girlfriend. The saturday, we decided to go to 'la ruta del cares'. We went by car to a village called Cain. After that, we started to walk. It was awesome because it was a track between two high mountains. The river called Cares is flowing, so it's very relaxing. The complete route it's twelve kilometers, but we only did four. My girldfriend did really like it, we are planing to do the full route next year.

The place I go on holidays I live in Madrid. And I like this city. Hower, in summer holidays, I like to go a city called Santa Pola, which is near Alicante, in the east of Spain. My parents bought a small Bungalow fifteen years ago. Since them, I've been going all the summers there. What I like most is that there I can rest and going to the beach. It's very relaxing and I can disconnect. I can also take some ice creams. The problem is that there I don't have internet and I can't see my emails so often. Only when I go to a restaurant or bar can I surf in the internet.

The Spaniard's worries According to the last survey made by the Spanish public sociologic institute (CIS, centro the investigaciones sociológicas), the three most important problems are the unemployment rate, the economic situation and the corruption. Now I'm giving my personal opinion about these topics. It cannot be denied that unemployment rate is the worry of most of Spaniards. In fact, more than 80% of the survey respondents are concern about this problem. Before the crisis, the Spanish model was based on the construction. When the crisis arrived, many construction companies collapsed. As a result, many people were unemployment. In addition, many companies have made redundancy. The problem is worst for young people (because they don't have experience) and for people who are older than 55 years old. The second problem is the economic situation. From my point of view, is related with the unemployment. If people don't have a job, they'll have problems with their domestic economy. The third problem is the corruption. There are several examples: some political parties are under suspicion of illegal financing, the son-in law of the Spanish king is in charge of stealing public money, and the former president of the Spanish Confederation of Industrial Organizations is in prison.

My first writing in italki Hi everybody! My name is David and this is the first time I write in italky. Altough I have been studying English for many years, I think that I need to improve the speaking and writing. From my point of view, the best way of improving a languaje is practising it, so italki provides me a good chance to talk with English speakers. I'm a Spanish native speaker. I was born in Madrid, the capital of Spain, and I've been living all my live hear. I can help teaching Spanish.
