Hi my colleagues , I have a new class consisted of 6-10 adult whose professions 
 
are agricultural engineering.  This class will be a Speaking class but of course i �m 
 
going  to give importance to reading , listening skills as well.. Yet I badly need some 
 
useful  sources to prepare my lesson plans. It can be conversation activities or 
 
reading  passages . I wonder if any of you can have any suggestions for me....
 
Thanks a lot  in advance ...
