The FBI （Federal Bureau of Investigation) had found a new way to catch criminals by lookin

The FBI (Federal Bureau of Investigation) had found a new way to catch criminals by looking at their jeans. Scientists from the bureau reported at last weeks meeting of the American academy of Forensic Sciences in San Francisco that every pair of blue jeans has a unique wear pattern. The FBI has already used this "bar code "to place a suspect at the scene of a crime.

Richard Vorder Bruegge, a scientist at the FBI laboratory in Washington D. C. , and his colleagues developed the technique while helping to identify suspects who were robbing banks and setting off bombs ii1 Washington In April 1996, one of the gang was caught on film . He was wearing a mask, but part of his trousers was visible.

When the photograph was enlarged Vorder Bruegge noticed light and dark lines running across the seam of the man' s jeans. His team found that the pattern originated from slight imperfections introduced when the trousers were made. Workers sew the seams by pushing the fabric through a machine, and the irregularity of that motion stretches and binds the fabric . The colored layer of cotton in the raised portion is worn away, creating white bands.

The patches are more striking on jeans than other types of trousers because they are often al- lowed to become extremely worn, "People just keep wearing them, "says Vorder Bruegge.

The FBI analyzed the jeans of suspects in the Washington case. One pair had a pattern with over two dozen features that matched the jeans Vorder Bruegge's team photographed. At the tri- al, the defense called in a used jeans exporter as an expert witness who claimed the patterns were common to all jeans. He showed the court 34 similar pairs, but in each case the FBI could distinguish them from the accused . The suspect was convicted.

"To place a suspect at the scene of a crime" at the end of the first paragraph means that theFBI

A．has been able to prove a suspect guilty

B．will lead a suspect to the spot of a crime

C．were at the scene with the suspect.

D．caught the suspect on the spot

A Fire near WacoSix years later, in an about-face, the Federal Bureau of Investigation（FBI

A Fire near Waco

Six years later, in an about-face, the Federal Bureau of Investigation(FBI) admits that federal agents fired tear gas canisters capable of causing a fire at the Branch Davidian compound near Waco, Texas in 1993. But the official said the firing came several hours before the structure burst into flames, killing 80 people including the Davidians' leader, David Koresh.

"In looking into this, we've come across information that shows some canisters that can be deemed pyrotechnic in nature were fired—hours before the fire started,” the official said. “Devices were fired at the bunker, not at the main structure where the Davidians were camped out."

The FBI maintains it did not start what turned to be a series of fiery bursts of flames that ended a 51-day standoff between branch members and the federal government. "This doesn't change the bottom line that David Koresh started the fire and the government did not," the official said. "It simple shows that devices that could probably be flammable were used in the early morning hours. "

The law enforcement official said the canisters were fired not at the main structure where the Davidian members were camped out but at the nearby underground hunker. They bounced off the bunker's concrete roof and landed in an open field well, the official said. The canisters were fired at around 6 a. m., and the fire that destroyed the wooden compound started around noon, the official said. The official also added that other tear gas canisters used by agent that day were not flammable or potentially explosive.

While Coulson denied the grenades played a role in starting the fire, his statement marked the first time that any U. S. government official has publicly contradicted the government's position that federal agents used nothing on the final day of the siege at Waco that could have sparked the fire that engulfed the compound. The cause of the fiery end is a major focus of an ongoing inquiry by the Texas Rangers into the Waco siege.

The FBI official has NOT admitted that______.

A．the canisters were fired at the main structure

B．the canisters were fired hours before the fire started

C．federal agents fired tear gas canisters capable of causing a fire

D．other tear gas canisters that were not flammable or potentially explosive were also used

In May 2004, agents from the Federal Bureau of Investigation （FBI) showed up at Brandon Ma

In May 2004, agents from the Federal Bureau of Investigation (FBI) showed up at Brandon Mayfield's law office and arrested him in connection with the March 2004 bombing of a train station in Madrid(马德里), Spain. The Oregon lawyer was a suspect (嫌犯)because several experts had matched one of his fingerprints to a print found near the scene of the terrorist attack.

But Mayfield was innocent (清白的). When the truth was found 2 weeks later, he was set free from jail. Still, Mayfield had suffered unnecessarily(受罪), and he's not alone.

Police officers often use fingerprints successfully to catch criminals. However, according to a recent study by criminologist(犯罪学家) Simon Cole of the University of California, Irvine, authorities may make as many as 1,000 incorrect fingerprint matches each year in the United States.

"The cost of a wrong decision is very high," says Anil K. Jain, a computer scientist at Michigan State University in East Lansing.

Jain is one of a number of researchers around the world who are trying to develop improved computer systems for making accurate fingerprint matches. These scientists sometimes even engage in competitions in which they test their fingerprint-verification (核实) software to see which way works best.

The work is important because fingerprints have a role not just in crime solving but also in everyday life. A fingerprint scan may someday be your ticket to getting into a building, logging on to a computer, withdrawing money from an ATM, or getting your lunch at school.

The title of this article most probably is ______.

A．Fingerprint Evidence

B．Fingerprint and Computer

C．The Mistakes of Fingerprinting

D．Fingerprint Matching

Americans often try to say things as quickly as possible, so for some expressions we use t
he first letters of the words instead of saying each word. Many common expressions or long names are shortened this way.

BYOB is a short way of saying "bring your own bottle". The letters BYOB are often found at the bottom of a written invitation to a simple social event or gathering friends. For example, I decide to have a party on a Sunday afternoon. I might write a note saying, "Please come to the party, and BYOB." The bottle each person brings is what that person wants to drink at the party.

An invitation to a special event, such as a wedding, would never say BYOB. However, an invitation to all official or very special event often has other letters at the bottom of it. The letters are RSVP. The letters represent the French expression “repondez s'il vous plait”. In English, the words mean “Respond if it pleases you”. Americans use the letters as a short-way to say please answer this invitation.

Another expression ASAP is often heard in business offices. My boss might say she wants something done ASAP. It means as soon as possible. She also might tell me she wants something done by COB. That means she wants it finished by close of business, or the end of the workday.

Beginning letters often are used to represent the name of a university. A famous one is MIT. It is short for the Massachusetts Institute of Technology. Another major university is UCLA, almost no one ever says its real name, the University of California at Los Angeles. That takes too long.

Some American businesses are better known for the beginning letters of their name than for their complete names. For example, you may not have heard of the company called International Business Machines, but you probably have heard of the company by its short name IBM. And the American Telephone and Telegraph Company is much better known as AT. ＆ T. Many American government agencies are known by the beginning letters of their name, too. For example, the FBI is the Federal Bureau of Investigation. The FBI investigates criminal activity in the United States. Then there is the IRS, the Internal Revenue Service. It is not a very popular agency. It collects Federal taxes. Here is an example you already know. Can you guess what it is？ How about VOA, the short name of the "Voice of America". (416)

What is the main subject of this article？

A．The voice of America.

B．A short way of saying.

C．Introduction of famous companies.

D．Brief introduction of VOA

Drug Warriors Billy White was wearing a jacket with the word "POLICE" printed on the back

Drug Warriors

Billy White was wearing a jacket with the word "POLICE" printed on the back, and jeans. His piece was a Glock, a nine-millimeter pistol New Haven Police Department standard issue. Around him, White recognized state cops, special agents from the DEA, officers from the U.S. Marshal's office, FBI special agents, and other police detectives like himself. There were anti-drug case agents from the ATF, and intelligence officers from the police departments of nearby cities. White looked around. These were his people, his soldiers, the ones who would be by his side on the front lines. This was the New Haven Drug Gang Task Force, and Lieutenant Billy White was in charge of it.

It was 3 a.m., and most of the men had been up since the morning before. But none of them would sleep that night either. They had a big day ahead of them. Hours earlier, White had been in his office, preparing warrants. Meanwhile, the New Haven Airport had quietly filled with federal agents, flying in from New York and Washington, DC. They had then gathered at the western corner of the city. The team's field headquarters that night would be an empty building on the very edge of town. The 300-man team of federal agents, state police, and local police had gathered to discuss the next step in the war on drugs.

Drug Warriors Billy White was wearing a jacket wi

White listened as his friend Kevin Kline, an FBI special agent and one of the original members of the task force, was speaking to the law enforcement army. Kline laid out the battle plan for the morning's drug bust: the agents were to organize themselves into squads, forming arrest teams and back-up crews. The teams assigned to carry out raids received arrest packets containing the names, addresses, and photographs of each suspect, as well as search warrants issued by the federal court. At 5:3o a.m., the teams were to split up, each reporting to their designated sites to prepare for the final stage of the operation: making the arrests.

As he listened, White asked himself the same question that everyone else in the room must have been thinking. Could the team pull off a successful bust？ Born and raised in New Haven, White still remembered a time when New Haven was considered a peaceful town. In 1960, only six murders, four rapes, and 16 robberies were reported. But soon, the drug gangs set up shop, and the turf wars began. With the gangs came gang violence: drive-by shootings, innocent victims killed, murders in broad daylight. In 199o, there were 31 murders, 168 rapes, and 1784 robberies. "Back then it was hell," White recalls. "I thought, 'What are we doing？'"

At exactly 6 a.m., the task force executed a coordinated sweep, arresting 29 out of the 32 people on the list. The arrests in the New Haven area all proceeded without incident. Afterwards, FBI special agent Robert Grispino was struck by the cops' intense emotion. "It was quite a sight," he told reporters. "With some of the New Haven cops, there were tears in their eyes." Billy White, of course, was among them. "We got some big fish, too, guys that handled multi, multi, multi kilos," says White. Of the 29 arrested, about 13 were Colombian citizens. The task force had successfully arrested many of the importers and distributors that had connections with source companies. "The core organization that they arrested here in New Haven had direct connections with Miami, San Juan, and Cali," says Grispino.

Meanwhile, the entire Cali cartel leadership has been arrested by a Colombian police squad. Eight of the top nine Cali drug lords have given themselves up to Colombian authorities or been killed in gunfights with police. Today, New Haven residents are once again venturing out into the streets. The neighborhoods feel safer. In fact, the task force's operations have proven to be so successful that they have attracted national attention. As for Billy White and his team, they continue to do what they have always done. "I think we can win the war on drugs," says White. "I'll probably be gone by then. But I think someday, we'll work our way out of a job, and there won't be any more gangs left in this city."
