E.  Theoretical Framework
Based on Rodney Huddleston and Geoffrey K. Pullum, Grammar deals with the  sentenc
es’  form  and  the  smaller  units,  such  as  clauses,  phrases,  and  words. Compare  with  the  pronunciation  and  the  words’  stock,  grammar  of  the  Standard
English  is  much  more  stable  and  uniform;  there  is  remarkably  little  dispute  about what  is  grammatical  in  comp
liance with the rules of grammar and what isn’t.
22
It showed that the rules of grammar in Standard English is constant and there was little
disagreement in deciding which was the sentence was grammatical  correct or no. In

other words, if the students had mastered the English Grammar they will ease to use language and it seemed that by mastering English Grammar wouldn’t be confusing
anymore  for  them  to  understand  English  language  usage,  in  this  case  reading comprehension.
Based  on  Larry  Lewin,  reading  comprehension  is  an  activity  which  is  so complex  due  to  the  mind  which  works  so  hard  to  understand  the  written  language
while the eyes which move smoothly over the printed words.

It showed that reading comprehension  is  not  an  easy  job;  the  reader  has  to  work  hard  to  understand  what
they are reading. It cannot be done without the ability of the readers in reading. The problems that the students often face in reading comprehension are the
unknown  words.  In  fact,  beside  the  vocabulary  knowledge  of  the  students,  their grammar knowledge is also having a big impact in their successful in getting the goal
of  reading  activities.  In  understanding  a  text  containing  many  combined  words,  the readers should have knowledge about the sentence structure how the words put into
the text for helping them understanding the message of the text completely or getting the writer’s messages accurately.
A  student  can  be  said  as  a  good  language  student  if  he  can  communicate with  their  partner  well  without  finding  any  confusing  utterances.  The  well
communication in English showed that they have mastered the English Grammar. As the topic of the study, is to find out whether or not there is a significant
c orrelation between the students’ grammar mastery and their reading comprehension.
Therefore, it is conducted to find out the possible correlation between two variables through correlational statistics.
