1．国外老师上Social Studies这类课的时候，常常用到“成功冰山(Success Iceberg)”的例子。请你根据下面的图和相关文字叙述，按照要求用英语写一篇150词左右的文章。
Everyone is familiar with the phrase “Hard work is the key to success”．Some people think that luck is the only solution to success while many others believe that success includes compromise，persistence，dedication，and failures.To conclude it，I consider that “Success is an iceberg”．We are all acquainted with the structure of the iceberg which floats in the sea.Only a small portion of the iceberg is visible while the large portion is hidden under the water.Iceberg can be perfectly related with success.Achievement，which is seen by everyone，can be compared to the visible portion of the iceberg while the hard work behind success is the bottom of the iceberg.
