　　The　world　we　live　in　is　becoming　more　and　more　intolerable　because　of　environmental　destruction.　For　example　,　forest　destruction　results　in　decrease　of　planting　land　and　unpleasant　weather.　In　addition,　man　is　faced　with　problems　of　water　pollution　and　air　pollution.

　　A　lot　of　measures　have　been　taken.　Planting　trees　helps　improve　and　beautify　the　environment.　Besides,　laws　concerning　environmental　protection　have　been　put　into　effect　and　achieved　good　results.

　　However,　the　problem　of　environmental　protection　remains　far　from　being　solved.　On　the　one　hand,　the　environment　pollution　and　destruction　are　getting　worse　and　worse　in　the　modern　world.　On　the　other　hand,　the　lack　of　knowledge　about　the　importance　of　protecting　environment　hinders　the　solving　of　the　problem.　In　a　word,　there　is　a　long　way　to　go　before　we　enjoy　a　clean　and　comfortable　world.

　　　2、　The　Problems　of　Plastic　Bags

　　［参考范文］

　　Plastic　bags　have　found　their　way　into　a　wide　area　of　everyday　life.　They　are　applied　in　big　supermarkets,　ordinary　shops,　small　stores　and　street　markets.　People　put　in　plastic　bags　everything　they　buy.　They　no　longer　need　to　carry　cloth　bags,　leather　bags　or　basket　bags　with　them　when　go　shopping.　Obviously　it　is　very　convenient　for　plastic　bags　to　be　used　in　people’s　everyday　life.　They　are　also　very　cheap.　They　are　usually　offered　free　of　charge.

　　However,　plastic　bags　also　bring　us　side　effects.　Some　people　throw　away　plastic　bags　causally.　This　causes　the　white　pollution　to　our　environment　,　which　is　very　harmful　because　plastic　bags　can　not　disappear　by　natural　decomposition.　This　is　certainly　not　beneficial　to　our　future.

　　People　have　to　be　careful　with　the　use　of　plastic　bags.　They　should　make　sure　they　put　the　sued　plastic　bags　into　the　dustbin　when　they　want　to　dispose　of　them.　It　also　might　be　better　for　people　to　use　the　traditional　cloth　bags　to　hold　the　goods　they　buy　instead　of　using　plastic　bags.

　　3、How　to　Solve　the　Energy　Shortage如何解决能源短缺问题

　　［参考范文］

　　Energy　shortage　is　a　very　serious　problem　in　the　world.　Many　people　worry　that　energy　resources　on　the　earth　will　be　exhausted　if　we　use　them　in　an　unchecked　way.　This,　most　people　agree,　will　cause　serious　problems　and　even　crisis　and　jeopardize　the　survival　of　mankind　.

　　On　the　one　hand,　most　people　agree　that　the　problem　can　be　solved　in　one　way　or　another.　One　is　to　conserve　and　save　our　energy.　Energy　refers　not　only　to　coal,　oil,　or　natural　gases　but　also　to　goods,　land　and　water,　etc.　Most　countries　have　realized　the　wastefulness　in　their　using　of　energy.　They　are　trying　to　conserve　energy.　For　example,　some　countries　have　a　daylight　saving　system　to　use　less　electricity　for　lighting.　Some　cities　have　enforced　water　savers　at　public　such　as　restrooms　and　bars.　Some　have　enforced　serious　penalties　on　overuse　of　electricity,　water,　and　farming　land.　By　these　means,　people　hope　the　drain　on　energy　resources　could　be　slowed　down.

　　However,　conservation　alone　cannot　solve　the　problem.　Another　way,　perhaps　the　best　I　think,,　is　to　develop　new　energy　resources.　Obviously,　no　matter　how　hard　we　try　to　save　energy　resources　and　how　abundant　they　are,　we　will　use　them　up　sooner　or　later.　I　think　there　are　many　energy　resources　that　we　can　develop　and　utilize.　We　don’t　have　to　depend　only　on　the　current　conventional　energy　resources.　There　are　many　other　energy　resources　that　we　can　develop　such　as　nuclear　power,　waterpower　and　solar　power.　These　resources,　if　developed,　can　completely　replace　the　conventional　energy　and　thus　solve　the　problem　of　energy　shortage.
