reputation as a top destination has had negative effects on the rivers water quality.(Para 2)Previously,water quality in the Li River had suffered greatly from an increasing volume of tourists,many of whom frequently threw garbage into the river.(Para 2)Many tour boats contributed to the problem too.(Para 2)The growth in tourism also meant the local population rose rapidly,as well as the number of commercial and industrial enterprises.(Para 2)Water pollution levels increased,with more household and commercial waste ending up in the river.Water pollution is always a challenging problem at present like the previous situation of the Li River.Read the following sentences which describe the water polution and try to use cause-effect expressions to connect them so that they become more logical.1 l Countries develop fast and populations grow rapidly.(CAUSE)l People demand for water resources increases.(EFFECT)2lPeople rely heavily on the use of chemicals to increase crop production.(CAUSE)l Many water pollution problems occur.(EFFECT)3lHousehold waste is frequently thrown into the rivers.(CAUSE)lThe living environment of fish species is worsening.(EFFECT 1)lHuman health is being threatened(EFFECT2)Possible answer1:Since countries develop fast and populations grow rapidly,peoples demand forwater resources increases.Possible answer2:Countries develop fast and populations grow rapidly,which causes peoples demand for water resources to increase.1 l Countries develop fast and populations grow rapidly.(CAUSE)l People demand for water resources increases.(EFFECT)Possible answer1:People rely heavily on the use of chemicals to increase crop production.As a result,many water pollution problems occur.Possible answer2:Peoples heavy reliance on the use of chemicals to increase crop production brings about many pollution problems.2lPeople rely heavily on the use of chemicals to increase crop production.(CAUSE)l Many water pollution problems occur.(EFFECT)Possible answer1:Household waste is frequently thrown into the rivers.Consequently,the livingenvironment of fish species is worsening and human health is being threatened.Possible

urbanization,more cars are needed,which made air pollution worse.Therefore,urgent steps should be taken to alleviate this issue.Initially,industrial companies should apply the most cutting-edge technologies in order to adopt new forms of energy as substitutes for fossil fuels.Also,governments can carry out inspections regularly and fine industrial factories for abuses.As for individuals,they should raise environmental awareness try more environmental-friendly transportation means such as buses instead of private cars.With these measures,it is believed that the fresh air of our hometown will be preserved for generations to enjoy.Lets spare no effort to make contributions to alleviating air pollution problem of our hometown!Sample writingExchange drafts with a partner.Use this
