Hello Hoda,

Thanks for your informative post.  Aside from giving us information, what did you want to discuss?  Your post would be improved by adding a question at the end, or by applying this information to our city. 

In your post, you appear to be quoting a book or article.  In that case, you should put the words within quotes.  To put something in quotes, use the “quote” button in the format bar when you are posting, or use the following tags:

In addition to putting other people’s words within quotes, let us know where you got the information:  tell us the source and give us a link to the source.  For this, you can use the hyperlink button in the format bar.  It looks like this:

It is always important to identify the sources of your information and to give credit to those whose words you are using.  Otherwise it looks like you are trying to pass other people’s work off as your own. 

After putting the words of others within quotes and telling us the source, you can move on to your own original contribution.  Tell us what you think about it in your own words.  Tell us what you want to do with this idea.  Ask a question about it.  In this case, if you want to analyze Shiraz using this framework, say so.  And then start to make a list that we can add to.

If you just stick a quote here, it’s random information and we have no idea what to do with it.

In any case, here are a few grammar notes:
