1) Last week I taught my son swimming. 2) I am so sorry. I have just broken your favourite vase. 3) Father, look, we (может быть have bought- если допустим только домой пришли с магазина и сегодня купили игрушку и bought - купили некоторое время назад(дни недели), но только сейчас показывают отцу ) a new toy boat! 4)Alice bought a new dress last Saturday. 5) Fred rode his horse in the park yesterday. 6) Jane has already finished doing her room. It is very clean. 7) I chose this dress. Do you like it? 10) I'm not hungry. I have already had lunch.
