7．The morning was a bit cold，but Li Yanbo quickly got out of his warm bed．He picked up two plastic buckets（水桶） and rushed to the center of the village，where a fire truck arrives once a day to provide water for residents（居民）．About 4，000thirsty villagers come with their empty buckets and stand behind the truck，because the village's only reservoir（水库） has dried up．Rain hasn't fallen for six months．
Li，a 14-year-old student lives in Liguan village-about 60km away from Kunming．He has risen early to get water in the last three months．"My family gets two or three buckets of water every day．We use them for drinking，washing and cooking，"said Li．"If we save a little every day，then once a week we can have a shower．""My father planted two mu of broad beans（蚕豆） last autumn，but the field is so dry that he can't even plough（犁耕） it because of the drought（旱灾）．"said Li．"The rice is food for my family-my parents and younger brother．We have no money to buy rice from the market．"
In Li's opinion，there are more ways to prevent a drought，such as planting more trees．"It has taught me that，if we make full use of water，two buckets of water a day should be enough for four family members．We can recycle the water for multiple（多样的）uses．"said Li．"Every drop of water is very important．I hope people can realize this．"
