There are some people who always waste food in the dining-room,which is also a waste of the natural resources.In my opinion,we should develop the habit of saving food in our daily life.For example,if we can't finish it,we should buy less to avoid wasting.
还有一些人总是浪费餐厅食物,这样做浪费了自然资源,我觉得在我们日常生活中我们应该养成节约粮食的好习惯,比如：如果我们吃不了的话就少买,以避免浪费.（作文的话这样比较好）
