Li Ping，a Junior One student at High School was quite busy over the last winter vacation，not just with homework .Li，together with ten other classmates made a      group to call on people to join the Clean Your Plate Campaign(光盘行动).

The      students went to many restaurants and told the people the importance of      food. “Excuse me，do you know that 20 million people around the world still haven’t got enough to        ? Could you please not     food ?”They would say this kind of thing hundreds of times every day．   

      ,the activity has got the support of many people．In a restaurant in Chengguan District，the owner gives the guests who have eaten all the food they ordered a ticket．People can enjoy a       meal when they have ten tickets . More than 50 restaurants in Lanzhou have begun to offer          dishes and encourage their guests to take leftovers(剩菜)home.

Wasting food is a serious problem around the     ，not only in China. It's said that 1.3 billion tons of food ends up as waste last year. This is as    as one third of all the food in the world．The UN Environment Program and the Food and Agriculture Organization held a“ Think ,Eat，Save”program in January,2013 to help reduce food waste.
