题目内容

You can tell a lot about people by looking at their hair — 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 finding 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(氢) 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 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 local tap water. That’s probably because people usually cook their food with the local water.

Authorities can now use the information to analyze hair samples from criminals or crime victims and 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.

1.What do we know about the hydrogen isotopes according to Paragraph 3?

A. They are classified by size.

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.

2.Why is it possible to know where people are from by analyzing their hair?

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.

3.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

4.Which of the following can be the best title for the passage?

A. Water composition B. Change your hair

C. Hair detectives D. No way out

10.Some of the world's most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day.UNESCO( United Nations Educational,Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music,its significance,and its potential as a unifying(联合) voice across cultures.
      Despite the celebrations,though,in the U.S.the jazz audience continues to shrink and grow older,and the music has failed to connect with younger generations.
      It's Jason Moran's job to help change that.As the Kennedy Center's artistic adviser for jazz,Moran hopes to widen the audience for jazz,make the music more accessible,and preserve its history and culture.
"Jazz seems like it's not really a part of the American appetite,"Moran tells National Public Radio's reporter Neal Conan."What I'm hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and white anymore.It's actually color,and it's actually digital."
      Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost."The music can't be presented today the way it was in 1908 or 1958.It has to continue to move,because the way the world works is not the same,"says Moran.
     Last year,Moran worked on a project that arranged Fats Waller's music for a dance party,"just to kind of put it back in the mind that Waller is dance music as much as it is concert music,"says Moran."For me,it's the recontextualization.In music,where does the emotion(情感) lie?Are we,as humans,gaining any insight(感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts?Sometimes we lose sight that the music has a wider context,"says Moran,"so I want to continue those dialogues.Those are the things I want to foster."

28.Why did UNESCO set April 30 as International Jazz Day?D
A.To remember the birth of jazz.
B.To protect cultural diversity.
C.To encourage people to study music.
D.To recognize the value of jazz.
29.What does the underlined word"that"in Paragraph 3 refer to?C
A.Jazz becoming more accessible.
B.The production of jazz growing faster.
C.Jazz being less popular with the young.
D.The jazz audience becoming larger.
30.What can we infer about Moran's opinion on jazz?C
A.It will disappear gradually.
B.It remains black and white.
C.It should keep up with the times.
D.It changes every 50 years.

A.Exploring the Future of Jazz.
B.The Rise and Fall of Jazz.

D.Celebrating the Jazz Day.

2.A young person is said to have a behavior disorder when his or her behavior is noticeably different f rom that expected in the school or community.This can also be stated in simpler terms as a child who is not doing what adults want him to do at a particular time.Children with this disorder often seem to be behaving in different and socially unacceptable ways.
    Like learning disabilities,behavior disorders are hard to diagnose.There are no physical symptoms in the body that are observable or measurable.Behavior disorders are therefore identified by observing behavior patterns in the child over a period of time.If a child displays some of the following behaviors,he may be labeled with a behavior disorder:
◆Aggression and cruelty to people and animals.
◆Destruction of property-defacing or damaging things.
◆Little sympathy and concern for others.
◆Takes no responsibility for behavior.Also lies,cheats and steals easily.
◆Disregards (无视)rules and regulations.
    In addition to these general symptoms of a behavior disorder,there are other symptoms characteristic of more specific behavior disorders such as ADHD-this is the inattentive,can't-sit-still behavior.The attention can't last long and the behavior is impulsive at times.The child also seems quite distracted and forgetful.
     Behavior disorders come from brain injury,child abuse,and shock,etc.There have also been indications that it could be a genetic disorder.The behavior therefore is an involuntary response to these experiences and the child should not be blamed for his behavior.Since the child has problems controlling his behavior,it stands to reason that his performance in school will be affected.A child with a behavior disorder will feel bad about himself and that low self-esteem will be further worsened by the adults around him who do not treat his condition with understanding and willingness to help.
     Behavior disorders are best dealt with by behavior and psychological treatments.But,as with learning disabilities,accurate diagnosis is important and this must be over a length of time.It is also important in trying to modify the behavior to be clear about what is the behavior you are expecting.Make sure it is a rational expectation.For example,expecting a three-year-old to sit quietly through a long church service may not be reasonable,or demandi ng that a six-year-old does extra home work after a long day of school and extra curricular activities may be stretching the child's concentration and attention too far.Since some behavior disorders result from shocking and upsetting life experiences or brain injury,treatments should include helping the child to resolve and heal emotionally from the experience.The behavior could be corrected through emotional healing.In other words,when a human being is emotionally healthy,that is,can be aware of his intelligence and enthusiasm for life and his loving connectedness to other human beings,he automatically"behaves"rationally.
