Dear Anish,                                             
Here are the information about Manchester University.  
It is about 200 miles far away from London, and it     
has a very big schoolyard. You can live on the school  
or near the school. They have all sorts of course.     
I'm sure you will find one you like it. I know you    
are particular interested in Human Rights. So I will  
see that there is anything on their website (网址).    
I’ll send my friend Charlie meet you at the airport 
when you arrived. You met him a few years ago, but he  
has changed a lot since then, Both your aunt or I look 
forward to seeing you again.                           
     See you soon.
