Buses run n time, and many families wn cars. Travel is fast and cnvenient.The change happened because the gvernment built new rads and peple wrked tgether.Hw I feel — I feel prud and happy. Life is much easier nw.
Changes in My Hmetwn — EnvirnmentIn the past, the land was dry and sandy. Sandstrms ften cvered everything in dust. The hills were bare and lifeless.Nw, the land is cvered with green trees and flwers. The air is fresh, the water is clear, and birds have returned.The change happened because the gvernment and lcal peple planted millins f trees and never gave up.Hw I feel — I feel grateful and amazed. Our hmetwn has becme a greener, better place.
Changes in My Hmetwn — Living FacilitiesIn the past, peple lived in small, ld huses. There was n hspital nearby. Students studied in pr schl buildings.Nw, we have new huses, a mdern hspital, and a well-equipped schl.

Our life is mre cmfrtable nw, and I believe the future will be even brighter.
Each grup will put up their psters, and the entire class will vte fr the "Best Pster".
We started tday with tw pictures f Saihanba—ne frm 1962 and ne frm tday. Nw we knw the wrds t describe this amazing change: sandy → green, sandstrms → clean air, difficult → miracle. Remember: change is pssible when we wrk tgether and never give up.
