时间状语从句一、引入环节（歌曲欣赏）
You Raise Me Up When I am down and all my soul so weary And troubles come and my heart burdened be Then I am still and waiting here in the silence Until you come and sit awhile with me
You raise me up so I can stand on mountains You raise me up to walk on stormy seas
I am strong when I am on your shoulders
You raise me up to more than I can be
