Influence of Reading Interest and Vocabulary Mastery on Students' Reading Comprehension Ability

Reading interest and vocabulary mastery can affect students' reading comprehension skills. The level of reading comprehension ability in the high class has yet to show satisfactory results. The low interest in reading students is due to a lack of awareness of students to read; besides that, students' vocabulary mastery still needs to improve due to a lack of student's ability to interpret words.
