Reading Miss Evans On a beautiful afternoon in a year now long gone, a big ship set out on its first voyage from England to America. It was a new ship called the Titanic. For two days the Titanic went on its way over the sea. Then it entered an ice field and a big iceberg hit it. Everyone came out of their rooms. Men were putting the lifeboats over the sides of the ship down into the water. Then all the men helped the women and children get into the lifeboats. There wasn't very much time left. The iceberg was on one side of the ship. It was like a high white wall. on A woman came to the side of the ship. Her two children were in one of the lifeboats and she was very much afraid. "My children the life boat. I must go with them," the woman called to the people in the lifeboat. "There's no more room," someone called out. "If we take one more the lifeboat will sink." There was a young woman in the lifeboat called Miss Evans. When she heard the woman calling, she stood up on the lifeboat and touched one of the men on the arm. "Let me get back on the ship," she said. "Let that woman take my place. I have no children." "The ship is sinking," said the man. "You know that?" "Yes," said Miss Evans. "I know that."
