READTEXT and return values

First question :

How can I set the return value of READTEXT to a variable of type nvarchar.

Second question :

I have a table t1 with a ntext column n1.

The ntext column has has words separated by empty space.
Each word can be assumed to be of size <= 255 characters.

How can I extract all the keywords in the ntext column to a table t2 with a column word nvarchar(255).

Assume that the text in column n1 is big enough so that it cannot be cast into a nvarchar or any other simpler type.

Any help on this is greatly appreciated.
Please do provide a sample code.
