Помогите пожалуйста.Выпишите из текста предложения с прямой речью переделайте их в косвенную речь.A famous professor, who was a well-known specialist in mathematics and physics, had a very bad memory for a change. He was the author of many textbooks, and there were books by him on the shelves of every library, but he often forgot very simple things. One evening, a scientists club invited him: Could you give a lecture for our club members?
When he left the house, he forgot to take his key with him, and he didnt notice it until he was on his way home again. Its lucky that my wife is at home, he thought.
It was a very dark night, and when his wife looked down at him from the window, she couldnt see who was standing there.
The professor isnt at home, she said.
The professor didnt remember that he was standing in front of his house, besides he was thinking as usual about his lectures, so he said, Oh, Im sorry. Ill come another time.
And he went away.
