　　They meet on Mondays at lunch.

　　They are the coolest kids at Mendez High School in Boyle Heights, Los Angeles.

　　They are the Reading Club.

　　"This is truly the biggest club in the school，" said English teacher Rebecca Carriaga, who formed the group last year with librarian Kim Leng. The two of them have often reached into their own pockets to feed the book­reading fever of students, and the club now has 20 members and keeps growing.

Five years ago, English teacher Rebecca said it seemed that some students, many of whom had not been exposed to (接触) reading at home, were unwilling to read because they thought books were too difficult. So she tried to make them feel more relaxed by giving them books to read and then, rather than pass out written exams, she sat with each student to "interview" them about their impressions one­to­one.
