Here’s the conversion from direct speech to indirect speech:
Direct Speech:
My teacher said, "My children, this is the last lesson I shall give you. The order has come from Berlin to teach only German in the schools of Alsace and Lorraine. The new master comes tomorrow. This is your last French lesson. I want you to be very attentive."
Indirect Speech:
My teacher said that that was the last lesson he would give us. He told us that the order had come from Berlin to teach only German in the schools of Alsace and Lorraine. He added that the new master would come the next day. He further said that it was our last French lesson and that he wanted us to be very attentive.
