If I go to St Petersburg,I shall stay at that hotel. If you take a taxi you will come early. If we have a party we shall invite Boris. I shall make jam if I buy some apples. They will visit London if they go to England. I shall write him a letter when I find his address. He will have lunch in the office if he is busy. He shouts if he is angry. We shall have soup for dinner if I have the time to cook it. When I am ready to go I shall give you a call. I shall go there alone if you are late. When I go shopping I shall buy a hat. If I am cold I shall put on the cap. I shall tell him the news if I see him. If I am free tomorrow I shall clean the window.
