Verb conjugation of "ritardare" in Italian

There is a small misunderstanding about the homework. I can do them, but they will be too confusing? I am trying to find the article from where I took the sentences in order to ease the task for all students.
Press the start button in the green box to initiate the verb drills. Please note that you can choose which tenses will be asked but I think that leaving it as it is will be the most efficient in the long term. Be patient and learn steadily.
I wish you lots of fun and success in your French class, and a nice weekend with lots of snow. PS: I am so happy I found you, my Italian friend, because we can visit each other all the time now.
