There is/There are

         In sentences which say that something exists (or does not exist) somewhere, we usually use there as a kind of  preparatory subject, and put the real subject after the verb.
        There is/There are is a common phrase in English, used to indicate that something ?exists? or is in a certain location. The main subject follows the verb when there is/are is used.
