[1] The first Earth Day was in 1970. People were beginning to worry about what we were doing to our environment (环境). So they set up Earth Day to tell everyone about their worries.
[2] In 2007, organizers in over 150 countries planned over 4,000 big events. But Earth Day is not just about marches (游行) and big events. In the week around Earth Day (22 April) there were many thousands of smaller, local events. These events dealt with environmental problems in the neighborhood.
[3] The World Wide Fund for Nature made a list of 5 things that each person could do to save the environment.
·Don’t leave the tap running.
·Turn off lights when you leave a room.
·Turn off your puter every night.
·Wash your clothes, and yourself, in cold or warm water, not hot water.
·Dishwashers use as little water as possible.
[4] If we all do at least 2 of these all the time, we can make a big difference.

(答案→)To tell everyone about their worries
解析：
【小题1】推理题。根据文章第一段People were beginning to worry about what we were doing to our environment说明人们设立地球日的目的就是告诉人们他们对环境的担忧。
【小题2】细节题。根据第二段第二行In the week around Earth Day (22 April) 。
【小题3】根据第三部分第一行·Don’t leave the tap running.
【小题4】推理题。根据·Dishwashers use as little water as possible.说明这种机器可能可能用水较少，所以才会推荐我们使用这样的机器，以保护饮用水。
【小题5】除了文章中的注意点之外，还可以从不要乱扔垃圾，要循环使用等方面着手。
