in China's Guangxi Zhuang Autonomous Region．It attracts millions of domestic② and foreign visitors each year．However，its reputation③ as a top destination has had negative effects on the river's water quality．This report looks at the problem of water pollution and some actions that have been taken to deal with④ it[1]． Period 5　课时练案 课文整体教学(Using Language) Previously，water quality in the Li River had suffered greatly from an increasing volume⑤ of tourists，many of whom frequently threw garbage⑥ into the river[2].Many tour boats contributed to⑦ the problem too.Kitchens on board⑧ were using lots of oil，which was often thrown into the water.The growth in tourism also meant the local population rose rapidly，as well as the number of commercial and industrial enterprises⑨.Water pollution levels increased，with more household and commercial waste ending up⑩ in the river[3].In order to feed more people， Period 5　课时练案 课文整体教学(Using Language) more chemicals were used to increase crop production.These chemicals led to severe water quality issues，causing a decrease in the number of fish species[4].Local officials were concerned that the pollution was damaging the natural environment and felt that urgent steps should be taken to restore⑪ the river's original beauty[5].
