【正确答案】　　The pictures are true records of some people's unhealthy behavior；in which we can see all the wastes discarded：by the picnickers：refuse newspapers plastic bottles, tin cans, food wrappings and leftovers, The litter in the public places witnesses certain people’s uncivilized conduct for lack of social morality and the sense of environmental protection．Obviously，their foolish ehavior results in destruction of natural landscapes, violation of public sanitation，and pollution of environment． 　　These people may be unconscious of their wrongdoings，but it is this unconsciousness that is most worrying and shocking，for it signifies a deep-rooted bad habit that could hardly be rid of without sufficient education and social supervision． 　　Unfortunately，this phenomenon is not rare or occasional；Besides littering，many ill habits， such as spitting everywhere，making terrible noises regardless of time and place，rude or even violent manners toward others，etc.，are all incompatible with modern civilization。Although such people are in minority，their bad behavior is causing serious problems． 　　The effective measures to be taken to change the situation may include strengthening public education，making related laws and regulations，establishing strict social supervision and penalty systems． 　　I believe our society will become more beautiful and healthful when everyone is consciously watchful of his/her behavior．
