I know that transformations are one of the most difficult exercises and sometimes you get confused (and don't even try to fill in the exercise during the exam).
So, why don't you try these transformations at home? The more you practice, the better!
This is the face of my students when they don't understand something (usually while I'm still explaining it). Sometimes, they translate this face into words. And it's something like that: "I don't entender very mucho".
Well, one of this phenomenal moments took place this morning when we were going through conditional transformations. Do you know what I'm talking about? Those exercises in which you are given one sentence and you are asked to create a second sentence with the same meaning as the former but using different words. Brilliant. Well, I've been gathering some on line practice. Help yourselves!
