Modern festival-goers who worry about ending up with a dead mobile phone battery(电池) after days stuck in a muddy field with no electric plug power points may now have a solution——power boots(靴子).
Mobile phone company European Telco Orange has introduced a phone charging(充电) prototype—— a set of thermoelectric gumboots or Wellington boots with a “power generation sole” that changes heat from the wearer’s feet into electrical power to charge battery-powered hand-helds.
The boot was designed by Dave Pain, managing director at GotWind, a renewable energy company. Pain said the boot uses the Seebeck effect, in which a circuit made of two dissimilar metals conducts electricity if the two places where they connect are held at different temperatures. “In the sole of the Wellington boot there’s a thermocouple and if you apply heat to one side of the thermocouple and cold to the other side it produces an electrical charge,” Pain said. “That electrical charge we then pass through to a battery which you’ll find in the heel of the boot for storage of the electrical power for later use to charge your mobile phone.” These thermocouples are connected electrically, forming an array of multiple thermocouples (thermopile). They are then sandwiched between two thin ceramic wafers. When the heat from the foot is applied on the top side of the ceramic wafer and cold is applied on the opposite side, from the cold of the ground, electricity is made.
But the prototype boot does have one drawback. You have to walk for 12 hours in the boots to make one hour’s worth of charge.The passage is probably taken from _____________ of a website.
A.the business book | B.the sports book |
C.the science book | D.the health book |
What’s the main idea of the third paragraph?
A.How the boot works to make electricity. |
B.How long the boot can be used. |
C.Who invented the power boot. |
D.The weakness of the boot. |
Which of the following can replace the underlined word “drawback” in the last paragraph?
A.Benefit. | B.Disadvantage. |
C.Patience. | D.Function. |
The invention seems to be good news to those___________.
A.who like traveling in the wild |
B.who work at home |
C.who study at school |
D.who work at an office |
第三部分:阅读理解(共20小题,每题2分,满分40分)
I was helping in my son’s classroom when I spotted a poster that reads, “Sticks and stones may break my bones but words can break my heart”. I started thinking.
Teachers are such an important part of a child’s life. A teacher’s support determines how safe a child feels in school. His inspiration determines how much risk a child will take in the classroom, his understanding determines how important a child feels in school and his love determines a child’s motivating and attitude toward education. And the effect a teacher has on a child doesn’t end when the school bell rings at the end of the day. Rather, those feelings developed in the classroom go home with the child and, in a large part, determine what sort of evening the child and the family have. The importance of a teacher to a child is fantastic and cannot be over-emphasized.
All my children are fortunate to have remarkable teachers. Consequently, the three of them love going to school almost as much as they love using teacherisms, for example, one of Hannah’s favorite phrases in used when I mess up. She looks at me with understanding and says, “It’s okay to make mistakes, mama, because you’re only learning.” Rachael’s favorite phrase is used to start most of her jobs; with a glow in her eye, she says, “I’m just going to do my best, mama, because that’s all I can do!” But perhaps my favorite is Jacob’s response to his sisters when one of them says something he doesn’t like. With his hand on his heart he says, “Don’t say that because words can break my heart.”
Like most parents, I hear teacherisms daily. And every time I hear one, my heart floods with gratefulness for the wonderful teachers who make my children feel safe, important, and successful in the classroom, and who are helping my children achieve emotional good health. There is much talk today how to measure a teacher’s worth. I think we need only look at the students. Children mirror teachers’ words and actions, and the content of those reflections shows teacher’s greatness.
1.Teachers are important to students in that ___________.
A.they equip them with book knowledge
B.they help free the parents from worries

2.The three children’s examples are used to show that_______.
A.they are lucky to have wonderful teachers
B.they can eventually develop into good teachers
C.they are sometimes mentally hurt by the teachers
D.they have a successful performance in school
3.To his mother, what the boy says possibly sounds_____.
A.ridiculous B.convincing C.humorous D.inspiring
4.The underlined word “teacherisms” probably refers to “_________”.
A.how teachers normally deal with their students
B.what teachers usually say to their students
C.why teachers seem important to their students
D.where teachers agree with their students
Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.

C.facts and descriptions D. figures and conclusion
Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.
“We’ve been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we’ve been able to record this increasing quantity of atmospheric CO2 into the ocean.”
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
“As carbon dioxide dissolves (溶解) in the water, or seawater in this case, it forms a weak acid (酸), carbonic acid, ” Dore explains. “And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic.”
The seawater Dore and his colleagues have analyzed confirms what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
“It’s important to realize that the oceans are really becoming acidic。And it can have negative impacts on a whole variety of sea life from fish to coral. It’s potentially catastrophic.”

e. CO2 levels in the atmosphere go up.
A. a→b→c→d→e B. e→b→c→d→a
C.a→e→c→d→b D. e→d→c→b→a
3. Scientist Robert Dore came to the conclusion based on ________.
A. his research and analysis B. the expectation of other scientists
C.some former theoryD. a major cause of climate change
4. What does the passage want to tell us most?
A. It takes time to make a scientific study.
B. Atmospheric CO2 is doing harm to sea life.
C.Robert Dore is a committed and serious scientist.
D. Measures should be taken to prevent the potential catastrophe.

More teachers are starting off the school year with letters to parents and students to introduce themselves and set a tone (基调) for the year. The letters are a good way to start positive communication with parents, several teachers told Education World.
“I think it’s professional, ”said Dorothy Peselli, an English teacher at Sparta High School in Sparta, New Jersay, Peselli, who gives out the letters the first day of school, told Education World. “It gives parents an image of you as a professional. If you start communication off in a positive manner, you will have the parents on your side when you need them.”
In her letter to parents, Peselli encourages them to call or e-mail her with specific concerns about their children. “I want to work as a team to make sure that your child becomes an independent lifelong learner,” Peselli wrote to parents last September. She also telephones the parents of all her students at the beginning of the year.
Peselli includes with the letter a classroom handbook (手册) listing plans and rules. And she requires that both parents and students read and sign statements (included in the letter) when they read the handbook. The student letter also lists needed supplies and gives encouragement. “Please come to class ready to work and learn. This will be an exciting year for all of us,” it says.
Last year, Peselli taught at a different high school and parents there were “shocked”, but appreciative, that she had so much contact with them. “I received roses and a thank-you note from one boy and his mother,” Peselli said. She wished her own children’s teachers would take the time to write notes as well. “I never got a letter home from any of my daughter’s high school teachers.” she said, “It would be nice to know the background of some of the people who are teaching my daughter.”
