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.”
1.Which of the following can best replace the underlined word “colonize” in paragraph 1?
A. look for B. fight over
C. carry away D. gather on
2.How can a specialist know a person’s time of death?
A. By researching the habitual nature of flies.
B. By relying on the entomological evidence.
C. By distinguishing the appearance of flies.
D. By discovering a new detective method.
3.What can we infer about Musah’s approach from the last paragraph?
A. Scientists have published studies about it.
B. It is bound to make every cold case solved.
C. It may help accelerate the detection of cases.
D. It will be published in Analytical Chemistry.
4.Where most probably can you see this article?
A. In a science fiction. B. In a newspaper.
C. In a medical paper. D. In a novel.

Begin doing the work you love as soon as possible, even if you don’t get paid for it, or if you can only work at it part-time. Albert Einstein was unable to get a job as a physics professor. He could have said to himself, “Well, I just don’t have the work relative to physics. I should give up on it and settle for something else.” Instead, he wrote the two most famous papers when he was employed as a patent clerk. After their publication, there was not a major university in the world that would not have been glad to have him on their staff.
If you want to work as an artist and you are making a living as a waiter, don’t think of yourself as a waiter who hopes one day to become an artist. That puts the work you love somewhere off in the distant future. Rather, think of yourself as an artist, supporting yourself by waiter tables—and paint, or draw as much as you can. It is possible to earn a living wage as a waiter working 24 hours a week. That leaves plenty of time to devote to training or developing your craft(手艺)in the off hours.
While seeking the work you love, it helps to expand your awareness into the universe of all possibilities. You don’t want to be limited to the ideas of what you should do or what you have done before. Having opened to all possibilities, you can make a final decision and select the work you love as your own.
Doing the work you love requires that you be equally comfortable with the imaginative and the practical. It requires the ability to dream big dreams and the ability to face and master all the little details that make dreams come true.
1.According to the passage, perhaps Einstein once said to himself, “_______.”
A.Well, I just don’t have the work relative to physics. I should give up on it and settle for
something else
B.The job is just what I want, I should work very hard at it
C.I have to support myself by working as a patent clerk now, but I won’t give physics up
D.I must wait until I find my favorite job
2.If a person works 24 hours a week, he can________.
A.have enough spare time for his hobbies
B.have no time left to make his dream come true
C.do nothing else
D.make a good living
3.Which of the following is not implied in the last paragraph?
A.Sometimes the imaginative is different from the practical.
B.We have to take care of a lot of details before we make our dreams come true.
C.We shall do practical things rather than dream.
D.We shall dream big dreams and practice as well.
4.According to the passage, the author encourages us to ________.
A.start work quickly B.select job carefully and patiently
C.dream often D.make up our minds quickly
