Rewordify to Simplify Readings

In my World History I ESOL classes I have usually have 25 kids who have been in the US less than four years and half who have been here just two years of fewer.  So one thing I use is Google Translate when I am trying to get them to learn to write (they write in their native language and then translate it to English as the writing part is more important than the English part).  But there are also lots of words or even combination of words that make it tough to read a textbook or newspaper.  So for those (if they are done electronically), one option is to use Rewordify which literally simplifies what one is reading.
