Today,everything is changing.Our motherland is changing too.I was born in a poor city,there were no modern buildings around the city,I could saw much pollution all over the city.I remembered that,when i went home from school,i could hear noises from the factories everywhere,i was really angly about this thing.Because i thought it would affect the life of people.So i really hated the city at that time .I sometimes very admire other children in those modern city.Because the places were clean and quiet for everyone to live and work!              But nowadays,everything is changing ,the people are changing in everything,For example:first,people love to buy a lot of things when there are shopping or tarveling.second,they enjoy their trips everywhere;third,the buildings had built everywhere in my city,the pollution is much less then before,the air in the sky is fresh and clean.it is good for our health.and then ,the life of people are rich ,there are many changes in my city ,i hope you can come to our city one day ,and  let me introduce somewhere interesting to you ,i hope you will love it!               So i must study really hard now ,i will tyr my best to make my city beautiful and strong!i am sure i will change,everything will change too!
