Marcio, I want to take you to a new level of e-prime. You write perfect e-prime, now lets remove the vague words, i.e. something and other such types of words would include: anything, it, that, those, these, them or anything that you can say more specifically but choose to use a workd that defines more than what you attempted to write.
In your sentence 'If you can do these sentences then you have learned something', you could write it more specifically, and replace the 'something' with learned how to express yourself in e-prime.
are you getting it yet?
