Police recently caught the suspected Golden State Killer using a tool they could only have dreamed of decades ago, when a shocking series of murders shook California: a database filled with people’s genetic data (基因数据).

Police used an open-source database called GEDmatch to find relatives who matched genetic material taken from an old crime scene, then worked backward to identify and catch 72- year-old former police officer Joseph James DeAngelo.

GEDmatch’s 950, 000 users voluntarily upload and share their genetic information, making it accessible to others who share their own data — including law enforcement (执法). More than a dozen other similar platforms also exist. “If your relatives have contributed and you are part of even a family tree that appears online in one of these shared resources, you can be indirectly tracked through the combination of their DNA and the publicly available family history,” says Dr. Robert Green, a medical geneticist at Harvard Medical School.

Data sent to commercial companies like 23andMe, which has over 5 million customers, is much tougher for outsiders to access, but the case has still highlighted the issue of genetic privacy.

Although many genetic-testing companies have been asked to cooperate with legal investigations (调查), and clearly warn customers of this possibility, not all requests are honored. “23andMe has never given customer information to law-enforcement officials, ” a company representative told TIME.

The risks of keeping such sensitive data private are high. The potential for abuse exists; for example, insurance companies could theoretically use genetic data to refuse coverage (保险项目), Green says. But the systems in place to prevent misuse appear to be working. One is the Genetic Information Nondiscrimination Act,　 a 2008 law that protects consumers from employment and insurance discrimination related to genetics. As long as that’s the case, Green says, the good of genetic tests outweighs the bad.

Sharon Zehe, a lawyer for the department of laboratory medicine and pathology at the Mayo Clinic, takes a more cautious approach. “Family tree services can be fun, but make sure you are using a reputable organization that has strong privacy policies in place, ” she says. “Genetic data is biologically as important as a fingerprint.”

1.Who is the Golden State Killer?

A. Robert Green.　　 B. Joseph James De Angelo.

C. The author.　　 D. Sharon Zehe.

2.What drives the users to upload their genetic data?

A. The Police’s force.　　 B. Their relatives’ advice.

C. The boss’s order.　　 D. Their own willingness.

3.Who might misuse customers’ genetic data?

A. The police.　　 B. GEDmatch.

C. Insurance companies.　　 D. 23andMe.

4.What is the main idea of the text?

A. Genetic data is equal to a fingerprint.

B. A 72-year-old killer was put into prison.

C. Murders causes concern for genetic privacy.

D. Genetic information is shared on the Internet.

One of Britain's bravest women told yesterday how she helped to catch suspected （可疑的） police killer David Bieber -- and was thanked with flowers by the police. It was also said that she could be in line for a share of up to ￡30,000 reward money.

Vicki Brown, 30, played a very important role in ending the nationwide manhunt. Vicki, who has worked at the Royal Hotel for four years, told of her terrible experience when she had to steal into Bieber's bedroom and to watch him secretly. Then she waited alone for three hours while armed police prepared to storm the building.

She said: "I was very nervous. But when I opened the hotel door and saw 20 armed policemen lined up in the car park I was so glad they were there.”

The alarm had been raised because Vicki became suspicious of the guest who checked in at 3 pm the day before New Year's Eve with little luggage and wearing sunglasses and a hat pulled down over his face. She said: "He didn't seem to want to talk too much and make any eye contact （接触）." Vicki, the only employee on duty, called her bosses Margaret, 64, and husband Stan McKale, 65, who phoned the police at 11 pm.

Officers from Northumbria Police called Vicki at the hotel in Dunston, Gateshead, at about 11:30 pm to make sure that this was the wanted man. Then they kept in touch by phoning Vicki every 15 minutes.

"It was about ten past two in the morning when the phone went again and a policeman said ‘Would you go and make yourself known to the armed officers outside?'. My heart missed a beat."

Vicki quietly showed eight armed officers through passages and staircases to the top floor room and handed over the key.

"I realized that my bedroom window overlooks that part of the hotel, so I went to watch. I could not see into the man's room, but I could see the passage. The police kept shouting at the man to come out with his hands showing. Then suddenly he must have come out because they shouted for him to lie down while he was handcuffed （带上手铐）。

1.The underlined phrase "be in line for" （ paragraph 1 ） means _____.

2.Vicki became suspicious of David Bieber because __________.

3. Vicki’s heart missed a beat because _________.

4. The whole event probably lasted about _______ hours from the moment Bieber came to the hotel to the arrival of some armed officers.
