Once there was a parrot on sale in a pet store. It was a beautiful red and blue bird. It sat on a perch in the middle of the store, so that everyone could see it when they came in. The owner was very proud of it and asked a high price for it.
One day a man went into the store. "That's a beautiful bird,"he said to the pet store owner, "But why is it so expensive? Is it unsual bird?"
"No, it's not very unusual. It's expensive because it can talk," the pet store owner said.
"I see. How can I make it talk?" the man asked.
The pet store owner asked him, "Do you see those string tied to each of the bird's legs?"
"Yes," the man answered.
"Well, you pull those strings," the pet store owner told him."That will make the parrot talk."
The man asked,"Do you mind if I try?"
"Not at all," the pet store owner said.
The man walked up to the parrot and pulled the string on its left leg. The parrot said, "Good morning."
The man pulled the string on the parrot's right leg. This time the parrot said, "How are you today?"
"That's not very interesting, " said the man. "Any parrot could do that." Then he laughed, "But what wold happen if I pulled both strings at the same time?"
"I'll fall off my perch, you fool!" the parrot said.

While I was waiting to go into university, I saw in a newspaper a teaching job wanted at a school about ten miles from where I【小题1】. Because I was in great need of  【小题2】and wanted to do something useful, I applied(申请).
Three days later, a letter【小题3】. It asked me to see the【小题4】at Croydon. It proved to be a (n) 【小题5】journey —a train to Croydon station, a ten-minute bus ride and then a walk of【小题6】a quarter of a mile. As a result I arrived there, feeling too hot to be nervous. Clearly, the principal【小题7】opened the door. He was【小题8】and round.
“The school” he said, “has a group of twenty-four boys between seven and thirteen.”
I should have to teach all the 【小题9】except art, which he taught himself. I should have to divide the class into 【小题10】groups and teach them at three different  【小题11】, and I was not【小题12】at the thought of teaching maths —a subject which I didn’t do very well in at school. It was 【小题13】that I had to teach them on Saturday afternoon 【小题14】most of my friends would be 【小题15】themselves at that time.
Before I had time to ask about my salary(薪水), he got up to his feet. “Now,” he said. “You’d better meet my wife. She is the one who really runs this school.”
