It happened one morning 20 years ago．A British scientist Alec Jeffrey came across DNA fingerprinting: He identified the patterns of genetic material that are unique to almost every individual．His discovery changed everything from the way we do criminal investigations to the way we decide family law．But the professor of genetics at the University of Leicester, UK, is still surprised, and a bit worried, by the power of the technology he released upon the world．

The patterns within DNA are unique to each individual, except identical twins, who share the same pattern．The ability to identify these patterns has been used to convict（證明…有罪） murderers and to clear people who are wrongly accused．It is also used to identify the victims of war and settle disputes over who is the father of a child．

Jeffrey said he and his colleagues made the discovery by accident while tracking genetic variations（變異）．But, within six months of the discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents’ son．·In 1986, it was used for the first time in a British criminal case: It cleared one suspect after being accused of two murders and helped convict another man．

DNA testing is now very common．In Britain, a national criminal database established in 1995 now contains 2．5 million DNA samples．The U．S．a(chǎn)nd Canada are developing similar systems． But there are fears about the stored DNA samples and how they could be used to harm a person’s privacy．That includes a person’s medical history, racial origin or psychological profile．“There is the long-term risk that people can get into these samples and start getting additional information about a person’s paternity（父子關(guān)系）or risk of disease,” Jeffrey said．

DNA testing is not an unfailing proof of identity．Still, it is considered a reasonably reliable system for determining the things it is used for．Jeffrey estimates the probability of two individuals’ DNA profiles matching in the most commonly used tests at one in a billion．

1．According to the text, DNA testing can NOT be used in _______ ．

A．doing criminal investigations        B．deciding family law

C．clearing wrongly accused people     D．telling twins apart

2．DNA samples are not popular with all the people because _______ ．

A．the government in Britain establishes a criminal database

B．the US and Canada develop similar systems

C．DNA samples can be used to harm a person’s privacy

D．DNA testing is too expensive and dangerous now

3．Where will you most probably find this article?

A．In a guidebook．                   B．In a storybook．

C．In a science fiction．                D．In a scientific magazine．

4．Which is the best title for the passage?

A．Discovery of DNA testing by Jeffery     B．Practice of DNA testing in court

C．DNA testing in the present situation       D．Benefits and side effects of DNA testing

Joe came to New York from the Middle West, dreaming about painting. Delia came to New York from the South, dreaming about music. Joe and Delia met in a studio. Before long they were good friends and got married.
They had only a small flat to live in, but they were happy. They loved each other, and they were both interested in art. Everything was fine until one day they found they had spent all their money.
Delia decided to give music lessons. One afternoon she said to her husband:
“Joe, , I’ve found a pupil, a general’s daughter. She is a sweet girl. I’m to give three lessons a week and get $5 a lesson.”
But Joe was not glad.
“But how about me?” he said.” Do you think I’m going to watch you work while I play with my art? No, I want to earn some money too.”
“Joe, , you are silly,” said Delia. “You must keep at your studies. We can live quite happily on $15 a week.”
“Well, perhaps I can sell some of my pictures,” said Joe.
Every day they parted in the morning and met in the evening. A week passed and Delia brought home fifteen dollars, but she looked a little tired.
“Clementina sometimes gets on my nerves. I’m afraid she doesn’t practice enough. But the general is the nicest old man! I wish you could know him, Joe.”
And then Joe took eighteen dollars out of his pocket.
“I’ve sold one of my pictures to a man from Peoria,” he said, “and he has ordered another.”
“I’m so glad,” said Delia. “Thirty-three dollars! We never had so much to spend before. We’ll have a good supper tonight.”
Next week Joe came home and put another eighteen dollars on the table. In half an hour Delia came, her right hand in a bandage.
“What’s the matter with your hand?” said Joe. Delia laughed and said:
“Oh, a funny thing happened! Clemantina gave me a plate of soup and spilled some of it on my hand. She was very sorry for it. And so was the old general. But why are you looking at me like that, Joe?”
“What time this afternoon did you burn your hand, Delia?”
“Five o’clock, I think. The iron-I mean the soup-was ready about five, Why?”
“Delia, come and sit here,” said Joe. He drew her to the couch and sat beside her.
“What do you do every day, Delia? Do you really give music lesson? Tell me the truth.”
She began to cry.
“I couldn’t get any pupils,” she said, “So I got a place in a laundry ironing shirts. This afternoon a girl accidentally set down an iron on my hand and I got a bad burn. But tell me, Joe, how did you guess that I wasn’t giving music lessons?”
“It’s very simple,” said Joe. “I knew all about your bandages because I had to send them upstairs to a girl in the laundry who had an accident with a hot iron. You see, I work in the engine-room of the same laundry where you work.”
“And your pictures? Did you sell any to that man from Peoria?”
“Well, your general with his Clemantina is an invention, and so is my man from Peoria.”
And then they both laughed.

BUKHANNON, West Virginia—Two rescue teams slowly moved along a two-mile path on Monday night to the site of a coal mine explosion that trapped 13 miners, who had not been heard from since the early morning accident．
Meanwhile, at a nearby church, more than 250 family members and friends gathered, waiting for updates（最新報(bào)道）on the rescuers’ progress．
The miners were trapped at about 6:30 and many families weren’t informed of the accident until about 10 a．m-more than three hours after it happened．“It’s very upsetting, but you’ve got to be patient, I guess,” said John Helms, whose brother, Terry, was trapped in the mine．
The trapped miners were about 260 feet underground and about 10,000 feet from the Sago Mine’s entrance, said Roger Nicholson, general counsel from International Coal Group．
At a late night news conference, Nicholson said one team had advanced about 4, 800 feet in the four hours since entering the mine just before 6 p．m．Another team entered the mine about 30 minutes later．
He said the crew was very experienced, with some members having worked underground for 30 to 35 years．The miners were equipped with about one hour of breathable oxygen each．The company has not released the names of the miners．
The teams test the air about every 500 feet, and have to disconnect （remove） the power to the phones they use to communicate with the surface before doing that．“ We don’t want to be energizing anything if it’s in an atmosphere with burnable gases,” Kips said．
The cause of the explosion was not immediately known．High levels of carbon monoxide were discovered shortly after the explosion, which delayed rescue efforts, but those levels have since subsided（減退）, authorities said．
【小題1】According to the passage, we can infer that ________．

A．a(chǎn)ll the miners who were trapped underground were still alive
B．communication with the trapped miners was cut off
C．the two rescue teams entered the mine at the same time
D．the rescue started as soon as the accident happened
【小題2】If the first team advanced at an average speed, they could dig about _______ per hour．
A．1,000 feetB．2,400 feetC．1,200feetD．4,800feet
【小題3】Where can the passage be seen?
A．In a magazine．B．In a newspaper．
C．In a science book．．D．On an advertisement．
【小題4】Which of the following shows the position where the miners were trapped?
