Dear fellow students，

May I have your attention，please? Now I'd like to make a speech here．As we know，waste  1.      (become)a common scene on campus recently．Some pour the remains of a meal where there is still much 2.       (1eave)；others 3.      (simple)walk away after washing hands，leaving the water 4.      (run)；students leave the classroom every day5.      noticing whether fans are switched off．Has thrift(节俭)，one of the national tradition 6.      developed from our long history gone? 7.      so，find it back!

We don't have to take great pains to control waste，but action and a grateful heart are needed；thank the water that runs through our fingers，and save it for poor Arabian or African countries struggling in water8.      (short)；thank the light we enjoy because in poor areas，children share9.      dim lamp reading；thank all the paper we are able to use，for trees are cut down 10.      (satisfy)our needs；thank everything nature can offer and everything we can own.

Live and act，so the tradition of thrift will never fade．
