1 - если глаголы стоят в одном и том же времени (past simple тут, в основном)
2 - если придаточная часть содержит would
3 - если глагол стоит в past perfect (had found, had come и т.д.), что по сути обозначает предшествование.
I’m very happy too! I’m going to go on holiday in June. I’m going to London. It's one of my favourite cities. We are going there with my classmates and our teacher. We are going to see a lot of interesting places in London. First of all we will see Big Ben and the Houses of Parliament, the Thames and the Tower of London. Just imagine it! Then we are going to see Westminster Abbey, Trafalgar Square with Nelson's Column and the British Museum. My dream will come true soon, because we are going to take a ride on the London Eye and to watch the Changing of the Guard near Buckingham Palace. Unfortunately, we are not going to visit St Paul's Cathedral and Hide ParkI hope I'll learn a lot of useful information and take a lot of interesting photos. I'll send you some of them.
Keep in touch.
Best wishes,
Vlad
