Scientists have devised a way to determine roughly where a person has lived using a strand (缕) of hair, a technique that could help track the movements of criminal suspects or unidentified murder victims.
The method relies on measuring how chemical variations in drinking water show up in people’s hair.
“You’re what you eat and drink, and that’s recorded in your hair,” said Thure Cerling, a geologist at the University of Utah.
While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move.
Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes (同位素). The heaviest rain falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah.
Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months.
Cerling’s team collected tap water samples from 600 cities and constructed a map of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of rain systems.
“It’s not good for pinpointing(精确定位),” Cerling said. “It’s good for eliminating many possibilities.”
Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake.
The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair.
When Park heard about the research, he gave the hair samples to the researchers.
Chemical testing showed that over the two years before her death, she moved about every two months.
She stayed in the Northwest, although the test could not be more specific than somewhere between eastern Oregon and western Wyoming.
“It’s still a substantial area,” Park said “But it narrows it way down for me.”
1.What is the scientists’ new discovery?
A. One’s hair growth has to do with the amount of water they drink.
B. A person’s hair may reveal where they have lived.
C. Hair analysis accurately identifies criminal suspects.
D. The chemical composition of hair varies from person to person.
2.What does the author mean by “You’re what you eat and drink” (Line 1, Para.3)?
A. Food and drink affect one’s personality development.
B. Food and drink preferences vary with individuals.
C. Food and drink leave traces in one’s body tissues.
D. Food and drink are essential to one’s existence.
3.What did Cerling’s team produce in their research?
A. A map showing the regional differences of tap water.
B. A collection of hair samples from various barber shops.
C. A method to measure the amount of water in human hair.
D. A chart illustrating the movement of the rain system.
4.What is the practical value of Cerling’s research?
A. It helps analyze the quality of water in different regions.
B. It helps the police determine where a crime is committed.
C. It helps the police narrow down possibilities in detective work.
D. It helps identify the drinking habits of the person under investigation.

A city child’s summer is spent in the street in front of his home, and all through the long summer vacations I sat on the edge of the street and watched enviously the other boys on the block play baseball. I was never asked to take part even when one team had a member missing—not out of special cruelty, but because they took it for granted I would be no good at it. They were right, of course.
I would never forget the wonderful evening when something changed. The baseball ended about eight or eight thirty when it grew dark. Then it was the custom of the boys to retire to a little stoop(门廊) that stuck out from the candy store on the corner and that somehow had become theirs. No grownup ever sat there or attempted to. There the boys would sit, mostly talking about the games played during the day and of the game to be played tomorrow. Then long silences would fall and the boys would wander off one by one. It was just after one of those long silences that my life as an outsider changed. I can no longer remember which boy it was that summer evening who broke the silence with a question: but whoever he was, I nod to him gratefully now. “What’s in those books you’re always reading?” he asked casually. “Stories,” I answered. “What kind?” asked somebody else without much interest.
Nor do I know what drove me to behave as I did, for usually I just sat there in silence, glad enough to be allowed to remain among them; but instead of answering his question, I told them for two hours the story I was reading at the moment. The book was Sister Carrie. They listened bug-eyed and breathless. I must have told it well, but I think there was another and deeper reason that made them to keep an audience. Listening to a tale being told in the dark is one of the most ancient of man’s entertainments, but I was offering them as well, without being aware of doing it, a new and exciting experience.
The books they themselves read were the Rover Boys or Tom Swift or G.A.Henty. I had read them too, but at thirteen I had long since left them behind. Since I was much alone I had become an enthusiastic reader and I had gone through the books-for-boys series. In those days there was no reading material between children’s and grownups’ books or I could find none. I had gone right from Tome Swift and His Flying Machine to Theodore Dreiser and Sister Carrie. Dreiser had hit my young mind, and they listened to me tell the story with some of the wonder that I had had in reading it.
The next night and many nights thereafter, a kind of unspoken ritual (仪式) took place. As it grew dark, I would take my place in the center of the stoop and begin the evening’s tale. Some nights, in order to taste my victory more completely, I cheated. I would stop at the most exciting part of a story by Jack London or Bret Harte, and without warning tell them that that was as far as I had gone in the book and it would have to be continued the following evening. It was not true, of course; but I had to make certain of my new-found power and position. I enjoyed the long summer evenings until school began in the fall. Other words of mine have been listened to by larger and more fashionable audiences, but for that tough and athletic one that sat close on the stoop outside the candy store, I have an unreasoning love that will last forever.

Some Habits of Super Positive People
Life is full of positive experiences．Notice them．Notice the sun warming your skin, the small child learning to walk, and the smiling faces around you．Smell the rain, and feel the wind．Live your life to the fullest potential by enjoying the beauty of these experiences, and letting them inspire you to be the most positive version﹙看法﹚ of YOU．
Living a positive life is all about creating positive habits to help you focus on what truly matters. This is the secret of super positive people．Here are some simple ideas to help you follow in their footsteps．
1._________
Life's too wonderful to waste time with people who don't treat you right．So surround yourself with people who make you happy and make you smile．People who help you up when you're down．People who would never take advantage of you．People who genuinely care．They are the ones worth keeping in your life．Everyone else is just passing through．
2._________
Your life isn't perfect, but it does have perfect moments．Don't let the little things get you down．You've got plenty of reasons to look up at the sky and say, "Thank you, I will do my best to make this a great day．" So slow down and pause for a moment to stand in awe of（敬畏） the fact that you are alive, and that you have the ability to rediscover life as the miracle it has always been．
3._________
It doesn't have to be January 1st to give yourself a chance to make good use of your life．Every day is a new day to learn, grow, develop your strengths, heal yourself from past regrets, and move forward．Every day gives you a chance to reinvent yourself, to adjust who you are, and build on the lessons you have learned．It is never too late to change things that are not working in your life．Using today wisely will always help you create a more positive tomorrow．
4._________
It's the most positive, stress-free way to live, because the truth always reveals itself eventually anyway．So don't aim to be impressive, aim to be true．Those who are true are truly impressive．Being true means having integrity; and integrity is doing the right thing even when you know nobody is watching．
5._________
Today, give someone one of your smiles．It might be the only sunshine they see all day．Sometimes just a single genuine smile or praise can lift a person's spirits to new heights．At the right time, a kind word from a stranger, or unexpected encouragement from a friend, can make all the difference in the world．Kindness is free, but it's priceless．And as you know, what goes around comes around．
