In this week I explored the next links and I learn many ways to improve my English:  

About: Randall's Cyber Listening Lab: http://www.esl-lab.com/ 
I found many listening exercises and I did this: http://www.esl-lab.com/newyorktravel/newyork-travelrd1.htm for intermediate level. I liked this web site because include pre listening exercises, listening exercises, vocabulary activities and post listening exercises. This is a good option to understand the listening.

https://sites.google.com/site/pronunciationstuff/ this site is about pronunciation and I like it because I have already worked with these exercises in the phonetic class.

This activity http://www.uiowa.edu/~acadtech/phonetics/anatomy.htm  is very helpful because show us the organs of speech in an interactive way, I consider that is important to know what are the organs that we use to speak.

http://www.youtube.com/watch?v=8vBn2_ia8zM this video is very funny this show us that is important to know the correct pronunciation of the word to don’t  get confusion about the conversations.

And finally this web site is about speaking skills:

There are many sites to  practice the speaking, I like this : http://www.voki.com/ in this you can Create customized avatars.

• Add voice to your Voki avatars.
• Post your Voki to any blog, website, or profile.
• Take advantage of Voki's learning resources.

And you can find many interesting videos or songs like this: http://player.vimeo.com/video/22888883.  

All of these pages are recommended to people that is learning English, to intermediate and advanced too. Because there are many activities according their necessities, so is very important to visit and explore these pages.

in conclusion:
I agree the idea of to know the diffents ways to improve our pronunciation, writting, reading and speaking skills the activities are interesting, so I liked all of these information.
