标题：Build a campus garden
变化：A student wrote a letter to campus newspaper suggesting to make a campus garden for 2 reasons.
(A) Students can relax with flowers and trees
(B) there is an empty land behind the scientist buildings which is suitable for being a garden
态度：The guy disagrees
原因1：It's cold for most of time here. The only blooming time for plants is summer break. During rest of time when campus is full, the flowers can't grow, the campus garden is meaningless.
原因2：The empty land is gonna be used to expand the scientist buildings
