Cleaning windows is tricky enough at the best of times，but when the glass is on the world's tallest building it is a complete pain.Soaring 2，717 ft into the air above Dubai and with 1，292，500 sq ft of glass to keep clean，the ￡1 billion Burj Khalifa presented a unique problem for maintenance teams.
Dale Harding，the general manager of window cleaning company，said the firm installed ￡5 million of hi-tech equipment，including unique window-cleaning carousels which they designed，to ensure the Burj Khalifa looks its best.Twelve machines weighing 13 tons carry up to 36 cleaners，who use ordinary soapy water to wash down the Burj's 24，830 reflective windows in a process that takes three months from top to bottom.
Mr.Harding said the company，based in Melbourne，Australia，had been working overtime to get the Burj shining for Monday's grand opening ceremony.He said："It's an incredible construction.People are focusing on the height of the building but the pure size of it，the footprint，is huge.It's really 10-15 conventional buildings."
The work，which took more than one month from the start of last August，was so tiring that the team named themselves the "Men Of Steel".Mick said："We would abseil（沿繩下滑）about 200 ft down.As the building swayed about you were just left bouncing around on all your ropes.It was totally exhausting because you were up and down ladders all day.There was a platform inside where you could eat your lunch but you were a long way from your nearest toilet or water supply." The job is now set to enter the Guinness Book of Records as the highest rope access work ever completed.

3．Dear Laura，
Thanks for letting us to stay at your seaside house． Now， you might have heard from your neighbors about which happened on Saturday evening． When I was out a walk， my younger son， Tom， played football before your house． He made so many noise that the neighbors got quite angrily． Even worse， Tom broke one of the window of Mr． Wilson's house． Tom and I apologized to all the neighbors for the unhappy happenings， but promised to have the broken window repair soon． Tom said that we would not do such silly things any more． I am glad that your neighbors had forgiven us． They are really nice people．
Yours，
