ON NEW YEAR'S DAY Today is New Year day.As usual ,I still spent much time in playing instead of doing my homework. In the morning ,I went to climb the Huangqi Mountain with my cousins and an old friend.There were many schoolmates climbing mountain as well.We went to the top of the mountain directly without taking a rest.When we arrived the old temple ,we sat down and took a rest And dueeriering that time ,we talked about somethings ,enjoying the sights around us.The sun was hiding behind the trees and the wind was very cool.After a moment ,we started to go down the hill.While stepping on the stone ladder ,I saw the sight of city ,but to my surprise ,it seems that the city was being covered with haze so that I couldn't see anything clearly.How dirty the air was !I thought anxiously. I still remember the time when I climbed the mountain with my family in my children .And the air didn't look like what I saw this morning.Now Jieyang is developing more and more quickly ,but we shouldn't ignore the environment anyhow !

a question about 'as if ' Is there anyone could tell me the difference between ' he walked in as if he had bought the school '&'.....as if he would buy the school ' ? also I am not sure if they are wrong.
