Greetings Jeff.
Nice to hear that your family have such a great tradition, Jeff. Yes, we have a Sunday lunch, we really enjoy it. My mother cooks very nice food too. It's usually: a delicious soup, salads and cupcakes. My grandpa and grandma often come for saturday lunch and we enjoy it together.
Надеюсь не слишком коротко.
1.Where will u go tomorrow with your parents after dinner?
2Your sisters and brother had already written a letter to Santa?
В Present Progressive просто добавляешь "was" и окончание -ing
В Present Simple добавляешь в конце глагола "s"
В Past Simlpe добавляешь (если это правильный глагол) окончание -ed, (а если не правильный глагол) 2 форму
В Future Simple добавляешь "will" и все
Удачи!
1. You have to look after the countryside.
2. You should (если вы проходили ought to, то здесь он подойдет больше) visit my city. It's fantastic!
3. You mustn't swim in the sea today. It's dangerous.
4. You have to help your parents with housework.
5. You should do more exercise if you want to get fit.
6. You must keep to the path – there are bears in the wood.
Мой английский не perfect, но основываясь на правило, все верно.
