Sitting at a desk in a classroom all day can be pretty boring. With a bike, the reading class can be  (interesting) than before.

    The teachers in  school in the USA have tried this. The Read and Ride program (begin) five years ago. As part of the Read and Ride program, the teachers change the students' (desk) into exercise bikes. With this program, one classroom in the school has enough bikes for each student in class.  is possible for the students to ride bikes and read books at the same time. Even common classrooms have one bike at the back of them. The students who cannot sit still can use the bike  (do) exercise. The exercise bikes are not only good for the students' health but helpful in  (improve) the efficiency of the students' study. When students are bored with study, they can relax themselves  riding the bikes for a while.

    After keeping trying the program for one year, the teachers found that the students  took part in the program did much better in reading tests.  amazing it is!
