多亏了建筑者们的辛勤付出，自今年四月份以来长春南湖大桥的水幕瀑布成为了我们城市的又一道绚丽的新风景．下面是林立写给美国笔友Mike的邮件，请你将其补充完整，每空一词．

Dear Mike，    How is it going？ Here I have something new to tell you．    Since （1） 　　， Nanhu Bridge Waterfalls have been another attraction in Changchun． You know， （2） 　　to the builders， the project is a great success． People can not only enjoy the waterfalls in different shapes and colors， but also （3） 　　to nice music at the same time． You cannot imagine lots of people come here just for a look， （4） 　　they live quite far． The bridge is sometimes crowded （5） 　　many visitors， so policemen are there to keep things in order．    Welcome to my hometown this summer． Looking forward to your reply． Yours， Lin Li
