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（最新报道）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（减退）, authorities said．

    A．all the miners who were trapped underground were still alive

    B．communication with the trapped miners was cut off

    D．the rescue started as soon as the accident happened

2.If the first team advanced at an average speed, they could dig about _______ per hour．

 A．1,000 feet     B．2,400 feet           C．1,200feet        D．4,800feet

3.Where can the passage be seen?

     A．In a magazine．                    B．In a newspaper．

How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question, as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’（老年痴呆症）.
“If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up.” Said Dr. Robert Green, a Harvard geneticist.
“Every ache and pain,” Smith suggested, “could be understood as the beginning of the end.” “That ’s right. If you ever worried you were at risk for Alzheimer’s disease, then every time you can’t find your car in the parking lot, you think the disease has started.”
Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s. It was thought that people who got bad news would, for lack of a better medical term, freak out. But Green and his team found that there was “no significant difference” between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green.
【小题1】Which of the following is true about James Watson？

A．He doesn’t want to know his chance of getting a disease.

B．He is strongly in favor of the present genetic tests.

C．He believes genetic mapping can help cure any disease.

The mystery had reached its climax (高潮) The man had undoubtedly been murdered. However, no one present knew who could have killed such a kind person. It was therefore time to call in the great detective, who gave one searching glance at the corpse (尸体), and then used a microscope.

"Aha!" he jumped as he picked a hair off the dead man's coat "The mystery is a mystery no longer. We have only to find the man who lost this hair, and the criminal will be in our hands. " The chain of logic was complete, and the detective started to do his search.

For four days and four nights he moved unobserved through the streets of New York, scanning closely every face, looking for a man who had lost a hair. On the fifth day he discovered a man pretending to be a tourist and his head was enveloped in a cap reaching below his ears. The man was about to board the Gloritania, and the detective lost no time in following him on board.

"Arrest him!" shouted the detective, and then, drawing himself to his full height, he took out the hair. "This is his," said the great detective, "and it proves his guilt. "

"Remove his hat," ordered the ship's captain firmly.

It was discovered that the man had no hair.

"Aha!" said the great detective without a moment's hesitation. "He has committed not one murder, but about one million!"

At one time, computers were expected largely to remove the need for copies of documents because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.

It is difficult to measure the quantity of paper used as a result of use of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. “I feel in my bones this revolution is causing more trees to be cut down,” says Ted Smith of the Earth Village Organization.

Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers.

Does all this mean environmental concerns (环境问题) have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. “I guess people believe that the problem is taken care of, because of recycling (回收利用),”said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity. The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.
