T3

　　The letter proposes the school should open classes outside the classroom because good scenery will make the students focus and avoid boredom and the school has installed some benches and seats outside.

　　The student disagrees with the proposal.

　　First, there are too many distractions outside. Students will be distracted when friends are passing through.

　　Second, there aren’t enough seats available, it’s inconvenient for students to take notes if they have to stand there.
