Last week we were revising must, have to, dont' have, mustn't and should; we also learnt to use some prepositions of movement and how to write a formal e-mail (DON'T FORGET TO WRITE ONE AS HOMEWORK!!). Moreover, we started talking about the first condional as well. It is not bad, is it? ;-)
Here you have the keys to handout 23 , handout 24, and handout 26.
