Shaw Wrote a Play

Once a poor flower-girl, quite by chance, overheard a conversation between two gentlemen. One of the gentlemen was a professor of phonetics. He was saying to the other that he could teach an uneducated person to speak good English. The girl was very much interested in what they were talking about. She tried to hear every word.
The fact was that she had for a long time been thinking of learning to speak correctly, and now she saw an excellent chance for herself. If she improved her manner of speaking the owners of the big flower shop would give her a job. She asked the two gentlemen to buy a few flowers from her and tried to speak to there but they didn't listen to her and soon went away.
The next day the girl came to the professor's house and asked him to give her lessons. The professor was very much surprised. At first he refused to teach her, saying that it was no use even trying, but then he agreed.
The results of the first lesson were poor. She couldn't produce proper English sounds and was tired of endless exercises. But soon the processor discovered that she was a clever girl. She took a great interest in her lessons and never missed a chance of practicing the sounds. As a result, her English became so good that the people who met her thought that she was a real lady.
The story of the girl can be found in one of Bernard Shaw's most popular plays.

On a beautiful afternoon, in a year 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 entered an ice-field and was hit by an iceberg.
Everyone was told to come out of their rooms. The men were putting the lifeboats over the sides of the ship down into the water. Then all the women and children were helped into the lifeboats.
A woman came to the side of the ship. Her two children were in oil, of the lifeboats, and she was very much afraid.
“My children are in the lifeboat. 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 in the lifeboat and touched one of the men on the arm.
“Let me get back on to the ship,” she said. “Let that woman take my place. I have no children.”
“The ship is sinking,” said the man. “You know that?”
There was no time to talk. People helped Miss Evans to get back on to the ship. Very soon after that there was a great noise, and the “Titanic” went down under the water.
