As soon as a person dies, decomposition(分解) begins. And the first visitors arrive. “Within 5 to 15 minutes of death, flies or other insects begin to colonize the body.” says Rabi Musah, an organic chemist at the University at Albany.
She says different species turn up at different stages of decomposition. “So because of that, depending upon what entomological(昆虫学的) evidence you find, you can learn something about when the person died in terms of the timing of the death.”
Flies don't tend to stick around when disturbed by detectives. But they do leave behind eggs. The eggs are hard to tell apart by appearance alone, so specialists raise them until they hatch, a few weeks later—and they get a species ID and, with a little guesswork, a person's time of death. But Musah has come up with a more time-saving approach: chemical analysis of the eggs. She and her team investigated that method by first harvesting flies with pig-liver traps hidden throughout New York City. They collected the trapped flies and then chemically analyzed their eggs. And it turns out each species of fly egg has a unique chemical fingerprint—enough to tell the eggs apart without raising the eggs to maturity. The study is in the journal Analytical Chemistry.
Musah and her colleague Jennifer Rosati are now testing the method on a real case. “And once we do that we will be publishing some case studies to illustrate(阐明) that this is a method that can be used, and hopefully eventually it's something that will stand up in court, and something that could speed up detective work—or help deal with a cold case.”

Chuck was in my high-school English class.1.So, when he told me he had been accepted into the journalism program at the University of Missouri, I wasn’t surprised.
During the first year at college, Chuck stopped by school a few times. We talked about our work together several years before. We had raised money together for twenty-three sick and abandoned babies.2.. It was an activity that in some ways changed our formal relationship into a friendship.
In his second year in college, it was discovered that Chuck had lung cancer and had only a short while to live. So he left school and came home to be near to his loved ones.
About six weeks later, Chuck died.3.The youngest of nine children, Chuck was talented and full of promise. More importantly, he was a good person, a just man.
When I went to his funeral, his father asked to speak with me. He told me that before Chuck’s death, he chose six items to bury with him.4.He told me that Chuck had always kept the piece because he liked the message I had written to him at the bottom of the last page. In that little note, I affirmed his talent as a writer and I encouraged him to be responsible for the gift.
5.His taking my note with him forever offered me a great opportunity for influencing students’ lives. I felt inspired with a sense of purpose that was greater than ever: teachers have the power to affect hearts and minds for a long time.
A. It was a great loss for everyone, especially for his family.
B. Chuck helped to raise several thousand dollars.
C. Whenever I forget my purpose, I think of Chuck.
D. He was a writer of great promise.
E. My spirits were lifted up as Chuck was filled with the joy of life.
F. One of them was an essay he had written in my class some years before.
G. I was touched and grateful to Chuck who gave me a special gift that would change my life.
