The thought bothers me. If I read I will therefore write. I have taught students to read but writing was an extra effort that usually didn't occur naturally. On the otherhand I don't think that a person can write without being able to read (except for maybe a few limited words, such as their name). so I used "then" in place of "therefore" but of course got it marked wrong because I was injecting another idea.
@Paulenrique, how do you say "We read, LATER, we write" then? "mais tarde"?
It makes more logical sense for me to translate it to "later" here instead of "so/therefore": "we read (now), and later we write", instead of "we read, so/therefore, we write" where there is no cause and effect relationship.
