An Australian researcher is urging parents to load up their teenager’s backpack and make them walk to school.
Professor Leon Straker says students who walk or cycle to school are less likely to have back and neck pain. But the study of 1,202 Western Australian 14yearold found that 72% of students travelled to school by car or bus. Straker says the study suggests walking or cycling while carrying a schoolbag helps improve trunk (躯干) and spinal (脊柱的) muscle strength.
This helps reduce back pain because greater muscle strength improves support for the back during load carrying .Despite advocating that parents get their children moving，Straker warns bag load should not exceed (超过) 15% of body weight.
Straker says the study also stresses that neck pain is as common as back pain among young teenagers. This is an area that has been largely ignored，he says，but can be an important indicator of neck pain into adulthood.
For the study，students were asked a series of questions such as how long they carried their bags for，how they carried their schoolbags，the method of travel，and their perceptions(感觉) about the bag’s weight.
Straker says about half of all participants experienced back and neck pain，with slightly more females reporting neck pain. However，the gender (性别) difference may also be due to the fact that females have lower pain tolerance.
Studies from the 1980s found carrying a bag over one shoulder was most common among teenagers. However in this study 85% of participants carried their bag over both shoulders.
Straker believes the change has been driven partly through education campaigns，but also by increasing fashion status of backpacks and improved design.In the opinion of Leon Straker，parents should________.
| A．reduce the load of their children’s schoolbags |
| B．put more books in their children’s schoolbags |
| C．get their children’s schoolbags ready for school |
| D．ask their children to walk to school carrying schoolbags |

In a recently published book, I came across some exercises with interesting names such as fishbone diagrams, lotus flowers and clustering. As I used these exercises in my classes, I noticed that students were interested. They said more and wrote more. They enjoyed expressing their ideas and sharing them in groups. They were no longer passively waiting for the bell , but actively taking part in the lesson. I find that creativity can act as a way to increase participation and improve fluency.
Creativity has become a popular word in recent years. Scholars in arts, psychology, business, education and science are all working to get a deeper understanding of it. Robert J. Stemberg is a creativity specialist and Yale professor of psychology. He defines creativity as “the ability to produce work that is both new (original） and appropriate(applicable to the situation ） ”. This definition is useful, as we want our students to use language in a new way and to use it correctly and properly. Mot scholars say there are two types of creativity: big “C” creativity and small “c” creativity. Big “C” creativity refers to genius level thinking that results in artistic masterpieces and scientific breakthroughs. Small “c” creativity refers to everyday level thinking that can be used in any situation our emphasis is on the latter. While it goes without saying that any of our students could go on to be the next Picasso or Edison, our aim is to help students produce more ideas and use language in a new way. The underlined words “waiting for the bell ” in the first paragraph probably means______.
| A．longing for a phone call | B．hoping to have a bell |
| C．expecting the end of the class | D．waiting to speak in the class |
It can be inferred from the passage that the author thinks the exercises in the book were _____.
| A．popular | B．useful | C．scientific | D．Creative |
When you use a familiar word in a new way, you are ________.
A creative in the sense of big “C” creativity.
B. creative in the sense of small “c” creativity..

D. not creative in the sense of small “c” creativity.The main purpose of the passage is to _________.
| A．show how useful the book is |
| B．explain what creativity is |
| C．discuss how one can be creative |
| D．tell what teaching aims at |
How many people have I met who have told me about the book they have been planning to write but have never yet found the time? Far too many.
This is Life, all right, but we do treat it like a rehearsal (排演）and, unhappily, we do miss so many of its best moments.
We take jobs to stay alive and provide homes for our families always making ourselves believe that this style of life is merely a temporary state of affairs along the road to what we really want to do. Then, at 60 or 65, we are suddenly presented with a clock and several grandchildren and we look back and realize that all those years waiting for Real Life to come along were in fact real life.
In America they have a saying much laughed at by the English：“Have a nice day” they speak slowly and seriously in their shops, hotels and sandwich bars. I think it is a wonderful phrase, reminding us, in effect, to enjoy the moment: to value this very day.
How often do we say to ourselves, "I'll take up horse-riding (or golf, or sailing） as soon as I get a higher position," only to do none of those things when I do get the higher position.
When I first became a reporter I knew a man who gave up a very well paid respectable job at the Daily Telegraph to go and edit a small weekly newspaper. At the time I was astonished by what appeared to me to be his completely abnormal (反常的） mental state. How could anyone turn his back on Fleet Street in central London for a small local area？I wanted to know.
Now I am a little older and possibly wiser, I see the sense in it. In Fleet Street the man was under continual pressure. He lived in an unattractive London suburb and he spent much of his life sitting on Southern Region trains.The first paragraph of the passage tells us that_______ .
| A．we always try to find some time to write a book |
| B．we always make plans but seldom fulfil them |

The man ( paragraph 6） left his first job partly because he was______.
A. in an abnormal mental state B. under too much pressure
C. not well paidnot respectedWhat is probably the best title for the passage?

Childhood was an illusion (错觉）and the illusion was this: everything was bigger. No, I mean everything, not just houses and shops and grown-ups, but colors and flowers and journeys, especially journeys which seemed endless. “Are we there yet, Daddy?”
Funfairs (游乐场） were huge things that spread for miles around you with noise and lights and exciting danger. Rainy days at home when you were ill seemed to last for ever. Being a grown-up yourself was an unthinkable distant possibility. Every sound was louder, every game was grander, every pain unbearable.
As I’ve grown old, life has become smaller. Tastes have dulled. Surprises have turned into shocks. Days go by unnoticed. How can I regain childhood when it was an illusion?
I have only one repeatable and wonderful way and even in this way I can regain only part of that larger world. I can play upon the stage like a child and make the crowd laugh and laugh with them, sometimes helplessly like a child, and then, even though I’m a sixty-one-year-old man, I can almost catch the colors and sounds and stillness of those bigger years when I was little.How does the author feel about his childhood?
| A．It was endless. | B．It was unpleasant. |
| C．He is glad that it is over. | D．He misses it as a grown-up |

Instead of hitting the beach, fourteen high school students traded swimming suits for lab coats last summer and turned their attention to scientific experiments.
The High School Research Program offers high school students guidance with researchers in Texas A&M’s College of Agriculture and Life Sciences. Jennifer Funkhouser, academic adviser for the Department of Rangeland Ecology and Management, directs this four-week summer program designed to increase understanding of research and its career potential.
Several considerations go into selecting students, including grades, school involvement and interest in science and agriculture. And many students come from poorer school districts, Funkhouser says, “This is their chance to learn techniques and do experiments they never would have a chance to do in high school.”
Warner Ervin of Houston is interested in animal science and learned how to tell male from female mosquitoes(蚊子）.His adviser, Craig Coates, studies the genes of mosquitoes that allow them to fight against malaria and yellow fever. Coates thought this experience would be fun and helpful to the high school students.
The agricultural research at A&M differs from stereotypes. It’s “molecular(分子）science on the cutting edge,” Funkhouser says. The program broadened students’ knowledge. Victor Garcia of Rio Grande City hopes to become a biology teacher and says he learned a lot about chemistry from the program.
At the end of the program, the students presented papers on their research. They’re also paid $600 for their work-another way this program differs from others, which often charge a fee.
Fourteen students got paid to learn that science is fun, that agriculture is a lot more than milking and plowing and that research can open many doors.The research program is chiefly designed for _______.
| A．high school advisers from Houston |
| B．college students majoring in agriculture |
| C．high school students from different places |
| D．researchers at the College of Agriculture and Life Sciences |
It can be inferred from the text that the students in poorer areas ___________ .
| A．had little chance to go to college |
| B．could often take part in the program |
| C．found the program useful to their future |
| D．showed much interest in their high school experiments |
When the program was over, the students ________.
| A．entered that college | B．wrote research reports |
| C．paid for their research | D．found way to make money |
The underlined expression “on the cutting edge” in paragraph 5 means “on the most ___ position”.
| A．important | B．favorable |
| C．astonishing | D．advanced |
When a Swedish ship that sank in 1628 was recovered from the port of Stockholm, historians and scientists were overjoyed with the chance to examine the remains of the past. The ship construction showed how ships were built and operated during the seventeenth century. In this way, artifacts, objects made by human beings, provided a picture of daily life almost 400 years ago.
Underwater archaeology-the study of ships, aircraft and human settlements that have sunk under large bodies of water-is really a product of the last 50 years. The rapid growth of this new area of study has occurred because of the invention of better diving equipment .Besides the Swedish ship wreck(残骸），underwater archaeologists have made more exciting discoveries such as the 5000-year-old boats in the Mediterranean Sea.
Underwater archaeology can provide facts about the past. In ancient ports all over the world are ships sunken in the past 6,000 years. There are also sunken settlements in seas and lakes telling of people’s way of life and their systems of trade in ancient times. Underwater archaeologists want to study these objects to add to the world's knowledge of history, but they have to fight two enemies. One enemy is treasure hunters who dive for ancient artifacts that they can sell to collectors. Once sold, these objects are lost to experts. The second enemy is dredging machines(挖掘机）often used to repair ports. These machines destroy wrecks and artifacts or bury them deeper under sand and mud. By teaching the public about the importance of underwater “museums” of the past, archaeologists are hoping to get support for laws to protect underwater treasures.What purpose does Paragraph 1 serve in the passage?
| A．To provide background information of the topic |
| B．To attract readers' attention to the topic |
| C．To use an example to support the topic |
| D．To offer basic knowledge of the topic |
The aim of underwater archaeology is to_____.
| A．exploit water bodies | B．search for underwater life |
| C．study underwater artifacts | D．examine underwater environment |
Underwater archaeologists are worried because_____.
| A．sea hunters have better diving equipment |
| B．their knowledge of world history is limited |
| C．dredging machines cause damage to the ports |
| D．sold artifacts can hardly be regained for research |
What is the main purpose of the passage?
| A．To introduce a young branch of learning. |
| B．To discuss the scientists’ problems. |
| C．To explain people’s way of life in the past. |
| D．To describe the sunken ships. |
