It's the day after Christmas. Last night the Dicksons had a party at their house. What had they done and what hadn't they done before they went to bed? 1. (they /open / all presents) Had they opened all the presents? Yes, they had. 2. (they/drink/lemonade) 3. (they/eat all the cake) 4 (they let cat in) 5. (they eat turkey) 6. (they tidy the room)
1. Jenny has to do her homework after school. В данном случае глагол have в 3 лице и единственном числе переходит в has
2. Tom must walk his dog every day. Здесь есть указатель every day, значит, нужно использовать Present Simple. То есть просто walk, без окончания -s, потому что есть must
3. Could you pass me the sault, please? Здесь не нужна частица to.
4. He needn't go to school on sunday. После need, should, must, could и тд глагол идет в Present Simple.
5. Should we buy a ticket? Do здесь не нужно, ведь есть уже should.
6. You must not park there. Как я уже упоминал, после must идет глагол в Present Simple.
7. She hasn't to go working every day. Здесь в значении "идти работать" - go working.
