You can tell a lot about people by looking at their hair 一 not just whether they brush,spray,or blow-dry. Scientists have found a way to use hair to figure out where a person is from and where that person has been. The fTnding could help solve crimes among other useful applications.
Water is central to the new technique. The liquid makes up more than half an adult human's body weight. Our bodies break water down into hydrogen (氫) and oxygen. Atoms of these two elements end up in our tissues,fingernails,and hair.
But not all Water is the same. Hydrogen and oxygen atoms can vary in how much they weigh. In the case of hydrogen,for example,there are three types according to their weights. Each type is called a hydrogen isotope (同位素) .And depending on where you live,tap water contains different isotopes.
Can hair record this information? That's what James R. Ehleringer,an environmental chemist at the University of Utah,wondered. To find it out,he and his colleagues collected hair from hair stylists in 65 cities in 18 states across the United States. Even though people drink a lot of bottled water these days,the researchers have found that people's hair has the same isotopes as found in the local tap water. That's probably because- people usually prepare their food with the local water.
Authorities can now use the information to analyze hair samples from criminals,or crime victims and to narrow their search for clues. For example,one hair sample used in Ehleringer's study came from a.man who had moved from San Francisco to Salt Lake City. As his hair grew,it reflected his change in location.
5. What do we know about the hydrogen isotopes,according to Paragraph 3 ?
A. They are classified by^?ize.
B. Each type of them differs in weight.
C. They can improve the quality of tap water.
D. Some of them cannot combine with oxygen.
6. Why is it possible to know where people are from by analyzing their Hkir?
A. People use the same bottled water.
B. People wash their hair in different ways.
C. People's hair is affected by the weather of the places they stay.
D. People's hair indicates the type of water in the places they stay.
7. The last paragraph is mainly to show .
A. how to recognize criminals
B. how to collect hair samples
C. the usefulness of hair analysis
D. the process of Ehleringer's study
8. Where does this text probably come from?
A. A lesson plan. B. A news report.
C. A physics textbook. D. A tourist guidebook.

Celebrities often have their own extraordinary life stories about their childhoods and their dramatic rises to fame. And here we have one example: Ella Fitzgerald,a girl from Harlem who became one of the most celebrated female jazz singer of the 20th century.
Bom in Newport News,Virginia in 1917,Ella didn，t want to be a singer at first. At 17,she entered a contest with a dream of becoming a professional dancer. But watching other dancers perform,Ella changed her mind right before going on stage ^ this was a turning point in her life^ She performed as a singer and won first prize.
After tliis unexpected debut(初次登臺) ，people began to hear about the girl with a pure singing voice,great rhythm,and perfect (音高) .And in 1935,Ella had a major breakthrough when the famous drummer Chick Webb decided to hire her for his band. Together they produced many hit songs,including “A-Tisket,A-Tasket/' which became Ella* s' first million-record seller. She also had a striking ability to make her voice imitate other musical instruments. This special talent made Ella begin to shine as she helped to pioneer a style called “scat” in the early 1940s. Scat,or wordless singing,uses random vocal sounds to copy the sounds of real musical instruments. Basically,scat singing is replacing the lyrics of a song with such nonsense syllables as “do be do be dos” while it keeps the tune (曲調(diào)) . Ella was a master of scat,elevating the style to a form of art.
After Webb's death,Ella continued her active singing career,touring with different jazz orchestras throughout the world. Celebrated as the top female singer of her time,she sold more than 40 million records. Ella received numerous awards and honors for her outstanding performance and talent. She died in 1996,but her music lives on,enchanting generations of jazz lovers.

I grew up in Philadelphia,Pennsylvania with my mother and elder sister. While we weren't rich,my mother managed to provide us with more than we needed and quite a bit of what we wanted. We had ups and downs,but mostly ups. One of my mother's favorite things to say was, “Well,try it and see." As a carefUl little girl,her words didn't do much to make me a real explorer of anything other than good books. However,my mother's words encouraging me to try harder,to climb and to reach new heights finally worked one day.
In December,2015,I had the extreme pleasure of visiting the South Pole,Antarctica to be exact. I once thought it would be the last place on the earth that I'd ever visit. First of all,I didn't vacation in a cold place. Second,if I did,it would be more like a lodge(鄉(xiāng)間小屋) on a mountain with a hot bathtub and a warm fire. But I went there.
It was a ten-day cruise that .produced more highs than I could have ever imagined. It was the longest time I'd ever been away from my children. I missed them so much that I had a few mild meltdowns(崩潰) ，but I recovered quickly after seeing a family of four crabeater seals swim right up below my deck. Somehow that moment of missing my children was soothed(撫慰) by God's wonderful works.
When I reached the highest point of Cuverville Island, after a scary and long trip up,I felt I had done something very meaningful. It was a journey for moms,for new entrepreneurs(企業(yè)家) and for the little girls who would dream bigger and do better because we showed them they could.

The next (繡球花) you grow could really save your life. A biologist at Colorado State University has taught plant proteins how to spot exp/osfves1 (炸藥) .
Picture this at an airport: A terrorist rolls through the sliding doors of a station with a bomb packed into his luggage. All of a sudden,the leafy,green hydrangea ringing the gates goes white 往s a sheet. That's the proteins inside the plants telling the authorities that they* ve picked up the chemical trace of the terrorist's explosive.
“Plants can't run and hide,” says June Medford,the biologist who's spent the last seven years figuring out how to get the plant to fight against terrorism. “If an insect comes by,it has to respond to it. And it already has its own particular way to respond.”
That would be the “receptor (受體)” proteins in its DNA. which respond naturally to threats. If an insect chews on a leaf,for instance,the plant releases a series of chemical signals called terpenoids,Medford says,that thickens the surface of the leaf in defense.
Medford and her team designed a computer model to direct the receptors: Basically,the computer program instructs the protein to react when it comes in contact with chemicals found in explosives or common air or water pollutants.
Right now,Medford's labs have genetically designed plants going white when they come into contact with explosives. But that's in a research lab,where the amount of light is constant.
Medford says her goal is to get her plants as sensitive as a dog's nose. But there is one big problem: Medford probably thinks it's not easy to get the plants to react to ammonium nitrate,a common chemical used for home-made bombs.
9. If the hydrangea discovers explosives,it will .
A. change color B. produce flowers
C. make its leaves thinner D. give off a special smell
10. The underlined word “it” in Paragraph 3 refers to.
A. the explosive B. the plant
C. the insect D. the terrorist
11. What do we learn about Medford's technology?
A. It will come into use in two years.
B. It has been studied for seven years.
G. It is chiefly based on medical science.
D. It can help spot ammonium nitrate easily.
12. What would be the best title for the text?
A. Fight against terrorism in your garden
B. Plants know how to respond to threats
C. Biologist develops bomb-spotting plants
D. Plant proteins hav^ been used to attract insects

Hip-hop music doesn’t typically remind us of the description “kid-friendly”. But Syracuse musicians Samar Moseley and Tyrone Jackson have found inspiration in their work as bus drivers for the Syracuse City School District. While other performers may rap about street violence or ill-gotten riches,this pair — known as 1306 — apply catchy beats to cautionary raps on bus safety and working toward graduation.
Last year,1306 put out a three-song record,Mr. Bus Driver,with positive raps on school-related issues. They also performed at city schools. In an interview,Moseley said that he thought 1306 could find a sizable market for its positive messages. Moseley is the songwriter while Jackson handles the beats and engineering. The pair,who started driving buses in 2011,are enthusiastic about what the foture holds.
They met during their bus driver training. The name 1306 came from Moseley's Bus Route 13 and Jackson's Bus Route 06. The concept behind that is going down a new journey and taking a new route to success. The first songs they did were club songs. One day,they both had a bad day on the bus,so they started talking about what happened and came up with the Mr. Bus Driver song.
“Driving a school bus isn’t an easy job. You have to let kids on the bus know that there are rules they should follow. The best way to teach something is to make it constructive and fun. Kids can learn the rules and have fun singing songs and dancing. It's a good feeling,” Jackson said. .
Their CDs have now become popular in other states. In Minneapolis,people play them in day care centers. After more than a year,1306 is still the only thing the kids in the centers want to listen to.
9. What makes 1306 different from other rappers?
A. Their club songs.
B. Their sunny smiles.
C. Their special experiences.
D. The themes of their songs.
10. Why did Moseley and Jackson choose the name 1306?
A. It was their new bus route number.
B. It combined their bus route numbers.
C. It reminded them of their bad days.
D. It is the combination of their birthday dates.
11. What's the purpose of 1306’s songs according to Jackson?
A. To comfort bored drivers.
B. To make kids learn music.
C. To teach people how to drive.
D. To help,kids behave themselves.
12. How is the last paragraph developed?
A. By time. B. By contrast.
C. By example. D. By space.
