A new term has begun. Teachers are   1   about the fact that new students are not easy to deal with. They like to bring cell phones and MP3 players to school. What is worse, some students even use cell phones   2   out-of-class matters in class, or sometimes just for fun. Some   3   students listen to MP3 players when they are having a lesson that they are not interested in.

Are these new students really that ___4____?  "Yes," says Delaney Kirk, a professor at Drake University. But she adds it's not their fault. 5  , the teachers should be blamed (责备). Mrs. Kirk first began thinking about students' manners six years ago.  "I had my first Class in which students were sleeping or talking to each other. It seemed that learning well had nothing to do with them," she says.  "At first, I got worried about this. But then I said to   6  ' You're giving lessons, and you need to manage this kind of situation. These students need to know more about manners. It's time to help them develop some good   7 They shouldn't waste time doing nothing when they are young. Sooner or later, they may regret the time they   8   '"

A young American doctor was sleeping when suddenly his doorbell began to ring. It was already midnight. But what could the doctor do? He had to put on his coat and go downstairs.

When he opened the door, he saw a man standing with his hat in his hand. “How do you do, sir?” said the man. “Can you come at once to a place out of town? It’s quite far but you have a car and I can show you the way.”

“Certainly,” said the doctor, “I’m quite ready. I can come at once.” In a few minutes the car was standing at the front door, and the man got on the doctor’s car. They drove on for a long time, then the man said, ”Here we are. This is my home. Now I can pay you and you can go back to town.”

“But I must see the patient,” the doctor said, “How can I go back without seeing the patient? Where is the patient?”

“There is no patient,” explained the man, “Nobody is ill. I live here. You see, one must go home from a town, mustn’t he? There are no taxis at this time of the night, but a doctor often makes night calls, so excuse me. Here is your money. Thank you, doctor. Good night.”
