爱尔安他们再一次分成小组走上街头时，是做民众环保意识的调查。这是政治老师布置的作业，要求每人至少调查五个对象，并把调查结果填在一张表格里。老师叮嘱说，询问时一定要有礼貌，可以说：“您有５分钟的时间吗？”如果别人没时间停下来回答也不能埋怨。需要回答的问题有 Elian once again divided into groups when they took to the streets, is to do public investigation of environmental awareness. This is a homework assigned by the political teacher, asking each person to investigate at least five people and fill in the survey results in a form. The teacher told me that when asked, be sure to be polite and say “Do you have 5 minutes?” You can not complain if someone does not have time to stop and answer. Need to answer the question there
