Function GetLyrics(FSO)

   Dim TextStream
   Dim S
   Dim File

    有多种方法可用来打开一个文本文件，和多种方法来从文件读取数据。
    这儿用了两种方法来打开文件和读取文件：

   Set TextStream = FSO.OpenTextFile(TestFilePath & "BeatlesOctopusGarden.txt", OpenFileForReading)
   
   S = TextStream.ReadAll & NewLine & NewLine
   TextStream.Close

   Set File = FSO.GetFile(TestFilePath & "BeatlesBathroomWindow.txt")
   Set TextStream = File.OpenAsTextStream(OpenFileForReading)
   Do    While Not TextStream.AtEndOfStream
      S = S & TextStream.ReadLine & NewLine
   Loop
   TextStream.Close

   GetLyrics = S
   
End Function
