There are a few ways to do this.
You could draw a block, curve the top path and then powerclip it inside the letters.
This is quick but to adjust you have to drill down into the powerclip to do the editing.
A second way is to:
Type your text - set the fill to a gradient
Draw a 2 point curve across the letters
Use the smart fill tool to create the lower cut off shapes.
Delete the cutting curve
This way it is a little easier to edit with the shapes on top.
