Last night I spent a few times to read NCE-2 lesson 71, descriptions a famous clock.

The writer said ‘If you visit to London,one of frist things you will see is big ben.The reason why the clock was erected is that the houses of parliament had been burned down in 1834.Big ben takes its name forom Sir Benjimin Hall,because he was responsible for making of the clock.It have immense size and is extremely accurate as well.Officials for Greenwich Observatory have the clock checked twice a day.So it never failed  to give the correct time, except the one time.Because a painter had been working on the tower hung a pot of paint on one of the hands,so slowed it down.

请各位老师、学友们帮忙纠正一下。我会有则改之，无责庆幸的！

谢谢咯
