Favorite Season

My favorite season absolutely is summer. Because in summer we can do a lot of interesting activities such as hiking, camping, kayaking, etc. For girls, the most important thing is that in summer we are able to wear all kinds of beautiful skirts, shorts, and dresses that cannot be used in cold seasons. Another positive thing about summer is that I can have ice creams or cold drinks as much as I want in hot summer. My favorite flavor of ice cream is dark chocolate or something with a fruit taste, like blueberry.

Clear paragraph.  Make sure to review subject/verb agreement.  If you are going to use girls (plural), then you need to use we (plural), not I (singular).  Try to make the paragraph flow more smoothly.  This is one reason why I put, "Another positive thing about summer is that..." This phrase helps the paragraph transition in a clearer and simpler way.    

I went shopping with my two best friends

This last weekend we were at the mall looking at the most beautiful dresses of all and the sexiest swimwear for them in the next vacation.
My friends and I bought enough shoes for the rest of the year, hehehe.
At the end of the afternoon we were so exhausted from the shopping that we had to go to the spa and relax with massages and aromatherapy.
Next weekend we are planning to make a trip to the Caribbean coast to wear our sexy costumes.

Good, clear paragraph.  Review your prepositions and use of compound sentences and relative pronouns.  

My last weekend

I went to Madrid on Friday and I ate in a Senegalese restaurant. On Saturday's morning I went to a demonstration and later I drank some beers into the night. At night some people went to my friend's house, and we celebrated his birthday. On Sunday's morning I slept and later I went to have lunch in one restaurant. Then I had coffee in an Arabian's restaurant. Finally, on Monday I went to have lunch at another friend's house and came back to Aranda.

Strong effort.  You have run-on sentences so be sure to review those rules.  Also, review the use of article and how the names of countries change when they become adjectives.  Try not to sound redundant, "I went, I did, etc."  Insert more variation into your sentences, and create compound sentences.  But good job!

In The Sky

There is something bright and nice in life, just like the star in the sky, which can be never touched. However, their very existence is enough already. They are the reason we live and also give/provide the comfort before our last breath.

There is something important in life. I hate low quality of life; I hate political news and officials' lies; and I hate that my time is wasted. If I can’t get the life I want, then life seems too long for me. Though what I pursue is really simple, why...why it is far from me?

This is a beautiful piece of writing.  There are not too many mistakes to correct.  Be sure to review when to use articles and when not to.  Also, with "officials' lies," you are talking about more than one official so the apostrophe should be at the end of the word.  A very good, thoughful, pensive piece.  

Noob on italki xp!!!!

Hi I'm Carlos and I'm from Spain where I live in Mérida, a little city with a lot of Roman monuments. I want to learn english so if you want, we can be partners on italki and I can help you with your Spanish. Add me ,,,, thank you everybody.
This is a photo of a ROMAN THEATRE in my city. Enjoy.

Hola Carlos! Muy bien! Make sure to review your rules on capital letters, when you need them and when you don't, as well as when to use the present vs. past modal.  I.e. can vs. could.  

italki! 3 years; I can't believe it!

Life is so magical!
It has been 3 years and 3 months since I have been here!
This time I'm ready for the TCSL and finding a language website.
Finally I returned to italki again!
I feel the web is an excellent medium; when i register i found i had been there! I'm not sure what you mean here.
I even found the composition i had written 3 years ago!
The most important thing is that i found foreign friends on Skype!
That feeling is a gift!

Make sure to review your perfect tenses.  I have eaten, you have eaten, etc.  Also, keep in mind that numbers under 100 are supposed to be written out.  I.e. three instead of "3." 

Keep up the good work!
