Have you ever thought, “I wish I could take a year off and just travel around the world”? Well, three lucky American teenagers were able to do just that. The teens—two males and one female--got an all-expenses paid, yearlong hike to five continents.
This trip didn’t include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment. They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with some of nature’s most dangerous animals and environments.
Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored (贊助) this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects.
The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.
As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person's actions. They realized that each of them can make a difference.
小題1:These teenagers went on the journey around the world _____.
A.to experience the most serous environmental problems on the earth
B.to bring the kindness of America to the other parts of the world
C.to go on sightseeing around the world
D.to call on more teenagers to join Earthwatch Institute
小題2:What’s true about their journey?  
A.They had to pay for their journey on their own expense.
B.They often had to move from one hotel to another.
C.They had to take great pains to collect environmental information.
D.They received a warm welcome every time they arrived at a new place.

The blue tits(山雀) have been inspecting the nest-box again this year. The male is the house-hunter but the female will make the final choice. He lands at the hole and turns his head to expose his white cheeks as a signal to attract the female from where she has been feeding.
Among many birds that nest in holes, the male has a light-coloured patch on its plumage(鳥羽) which acts as signal for drawing the female’s attention to a suitable nesting-place. Unlike the blue tit, the redstart(紅尾鴝) may be only the male that strikingly coloured and the female is not beautiful.
A few years ago I was lucky enough to spot a pair of redstarts in action in a Walsh wood. The male was leading an interested female to holes that he had previously(先前) checked out. He sat at the entrance of each hole and put his head on to show off his white forehead, or his head in to reveal(顯露) his tail.
If the female failed to react to his visual signals, the male sometimes sang for extra effect, while gliding towards her on spread wings and tail. Once the female accepts by following the male through the hole the displays stop, you must be at the right place at the right time to watch them.
小題1:How do the blue tits choose their nest?
A.They choose their nest together.
B.The male chooses their nest.
C.The house-hunter chooses their nest.
D.The female chooses their nest.
小題2:The writer was lucky to see ________.
A.how the male made his tricks
B.how an interested female played with the male happily
C.what the male displayed and won the female
D.that the male tried his best but failed to attract the female

No poem should ever be discussed or “analyzed”, until it has been read aloud by someone, teacher or student. Better still, perhaps, is the practice of reading it twice, once at the beginning of the discussion and once at the end, so the sound of the poem is the last thing one hears of it.
All discussions of poetry are, in fact, preparations for reading it aloud, and the reading of the poem is, finally, the most telling “interpretation” of it, suggesting tone, rhythm, and meaning all at once. Hearing a poet read the work in his or her own voice, on records or on film, is obviously a special reward. But even those aids to teaching can not replace the student and teacher reading it or, best of all, reciting it.
I have come to think, in fact, that time spent reading a poem aloud is much more important than “analyzing” it, if there isn’t time for both. I think one of our goals as teachers of English is to have students love poetry. Poetry is “ a criticism of life”, and “ a heightening(提升) of life”. It is “an approach to the truth of feeling”, and it “can save your life”. It also deserves a place in the teaching of language and literature more central than it presently occupies.
I am not saying that every English teacher must teach poetry. Those who don’t like it should not be forced to put that dislike on anyone else. But those who do teach poetry must keep in mind a few things about its essential nature, about its sound as well as its sense, and they must make room in the classroom for hearing poetry as well as thinking about it.
小題1:To have a better understanding of a poem, one should________.
A.discuss it with othersB.a(chǎn)nalyze it by oneself
C.copy it down in a notebookD.practise reading it aloud
小題2:Which of the following is NOT mentioned as a function of poetry?
A.Extending your lifeB.Saving your life
C.Criticizing lifeD.Heightening life
小題3:According to the writer, one of the purposes of teaching English is to get students________.  
A.to understand life.B.to enjoy poetry.
C.to become teachers.D.to become poets
小題4:What does the last sentence in the third paragraph imply?
A.More stress should be laid on the teaching of poetry.
B.Poetry is more important than any other subject.
C.One cannot enjoy life fully without an understanding of poetry
D.Poetry is the foundation of all language and literature courses
小題5:The phrase “make room” in the last paragraph could be best replaced by
A.“build a booth”B.“provide equipment”
C.“l(fā)eave a certain amount of time”D.“set aside enough space”

Cyber Cafe computer centers are found in many cities around the world. Now, a few American high schools are opening these centers. For example, high school in the state of Maryland began operating a Cyber Cafe last March. All students at Bethesde-Chevy Chase High School in Bethesda can use the Cyber Cafe. But school officials say I especially helps students who have no computer or cannot use the Internet at home.  
The officials say thirteen percent of the students at the school are from poor families. Many student have arrived in the United States from poor families. Many students have arrived in the United States from other countries only recently. Students in the school’s program for learning English speak twenty-three other languages.
The idea for a Cyber Cafe at Bethesda-Chevy Chase High School began three years ago. A that time, officials were planning o restore the school building. Parents interested in technology proposed a Cyber Cafe.
They wanted this center even though schools in the area had suffered budget cuts. The community wanted to help. It wanted all students to have the best chances to learn.
Officials in the area supported the idea. So did an organization called the Bethesda-Chevy Chase High School Educational Foundation. The foundation includes parents, teachers, former students, and business, community and other leaders.
Over two years, the foundation collected money for a Cyber Cafe and other new computers. It received more than one hundred seventy thousand dollars. The Café now has sixteen computer, a printer and a device called a scanner . School official Ann Hengerer (HEN-grr-er) says students use the Internet to complete research. They also write homework and required papers on the computers. In addition, they can send and receive electronic mails. That is especially helpful for the many students who have family members in other nations.
The Cyber Cafe also serves a social purpose. Visitors can stop by for a drink of coffee, tee or hot chocolate. On Long Island, in School has six computers in is Cyber Cafe. One student at the school says students can start their homework even before they leave school.

Electronic waste, or e-waste, refers to electronic products that are no longer usable. This can include TVs, cell phones and computers and other office electronics, electronic toys and videos machines. Today, the average turnover(更換)rate for a computer in the United States is every two years, according to the environmental group, Greenpeace.
The group's Dai Yun says e-waste is a global problem. "The electronic industry is one of the fastest growing industries in the world. The high speed of growth in this industry means more and more electronic products are being wasted and thrown away. If no one decides to retrieve the old products and process them properly, the electronic waste will sweep over the earth like the huge wave behind me and pollute the Earth seriously."
Greenpeace works out that 20 to 50 million tons of e-waste are produced globally each year. The components(部件)in many electronic products contain harmful chemicals that pollute ground water and the environment.
At present , the U.S. has no federal law for the disposal (處理) of e-waste although a few states have e-waste recycling programs in place, but there is no law. The U.S. exports much of its e-waste to third world countries, such as India and China, where workers took apart computers for valuable parts, hoping to sell them for money. But harmful wastes expert, Dr. Bakul Rao, says that's a dangerous practice. "From now on, the recyclers are not very educated. All they know is they can retrieve copper or gold out of it. So, the easiest way to do that is leach (過濾) it out in an acid or burn it off to retrieve it. So, that's where they don't know how to deal with it, neither do they have any health systems in place. So, their exposure is more."
小題1:Which of the following is most likely not to be a form of e-waste?
A.A mobile phoneB.A radio C.An e-bikeD.A table
小題2:What does the underlined word "retrieve" (paragraph 2) probably mean?
A.look intoB.take apartC.get backD.throw away
小題3:What of the following statements is true according to the passage?
A.The U.S. has strict national laws for dealing with e-waste.
B.Third world countries import e-waste to get valuable parts, which is a safe and easy way to
make money.
C.The way uneducated workers deal with old computers does great harm to the environment as well as to their own health.
D.More and more electronic waste is being wasted and thrown away mainly because of
people's bad habits.
小題4:What is the purpose of writing the passage?
A.To attract more people's attention to e-waste.
B.To call on people not to throw away e-waste anywhere.
C.To tell people what e-waste is and how to deal with it well.
D.To warn people to break away from the electronic industry.
小題5: The next paragraph probably concerns_______.
A.how to deal with e-waste properly
B.how to protect ourselves from harm by e-waste
C.How to slow down the development in the electronic industry
D.how to make full use of e-waste

The question of what children learn, and how they should learn, is continually being debated and redebated. Nobody dares any longer to defend the old system, the learning of lessons parrot-fashion, the grammar-with-a-whip system, which was good enough for our grandparents. The theories of modem psychology have stepped in to argue that we must understand the need of children. Children are not just small adults; they are children who must be respected as much.
Well, you may say, this is as it should be, a good idea. But think further. What happens? "Education" becomes the responsibility not of teachers, but of psychologists (心里學(xué)家). What happens then? Teachers worry too much about the psychological implications (暗示) of their lessons, and forget about the subjects themselves. If a child dislikes a lesson, the teacher feels that it is his fault, not the child’s. So teachers worry whether history is "relevant" to modern young children. And do they dare to recount stories about violence? Or will this make the children themselves violent? Can they tell their classes about children of different races, or will this encourage racial hatred? Why teach children to write grammatical sentences? Verbal expression is better. Sums? Arithmetic? No: Real-life mathematical situations are more understandable.
You see, you can go too far. Influenced by educational theorists, who have nothing better to do than to write books about their ideas, teachers leave their teacher-training colleges filled with grand, psychological ideas about children and their needs. They make elaborate, sophisticated (精致的,復(fù)雜的) preparations and try out their "modem methods" on the long-suffering children. Since one "modem method" rapidly replaces another the poor kids will have had a good bellyful by the time they leave school. Frequently the modem methods are so sophisticated that they fail to be understood by the teachers, let alone the children; even more often, the relaxed discipline so essential for the " informal" feelings the class must have, prevents all but a handful of children from learning anything.
8. People do not dare defend the old system mainly because under the old system________.
A. too much grammar was taught to children     B. children were spoiled (寵壞)
C. children were treated as grown-ups          D. children were made to learn passively(被動的)
9. What view do the modem psychologists hold?
A. Children must be understood and respected.
B. Children are small adults and know what they need.
C. Children are better off without learning lessons.
D. Education of children is the responsibility of psychologists.
10. What happens when teachers pay too much attention to the psychology of their lessons?
A. They find that the children dislike the lessons.
B. They tend to blame students for their failure.
C. They do not pay enough attention to the actual lessons.
D. They no longer want to teach children history.
11. Grammatical sentences are regarded as unimportant because ________.
A. it is better to use verbs only
B. words are said out of natural feelings only
C. talking freely and naturally without sentences is a better form of expression
D. it is felt that formal grammar rules might cause unnatural expressions
12. According to the passage, the modern methods are understood by ________.
A. neither teachers nor pupils      B. only a handful of teachers and pupils
C. the more sophisticated teachers  D. everyone who enjoys the relaxed discipline of the informal classes

Across the world, 1.1 billion people have no access to clean drinking water. More than 2.5 billion people lack basic sanitation.(衛(wèi)生設(shè)備)

The combination proves deadly. Each year, diseases related to inadequate water and sanitation kill between 2 and 5 million people and cause an estimated 80 percent of all sicknesses in the developing world. Safe drinking water is a precondition for health and the fight against child death rate, inequality between men and women, and poverty.
Consider these facts:
●The average distance that women in Africa and Asia walk to collect water is 6 kilometers.
●Only 58 percent of children in sub-Saharan Africa are drinking safe water. and only 37 percent of children in South Asia have access to even a basic toilet.
●Each year in India alone, 73 million working days are lost to water-borne diseases.
Here are three ways you can help:
1)Write Congress
Current U.S. foreign aid for drinking water and sanitation budgets only one dollar per year per American citizen. Few members of Congress have ever received a letter from voters about clean drinking water abroad.
2)Sponsor a project with a faith-based organization
Many U.S. religious groups already sponsor water and sanitation projects, working with partner organizations abroad. Simply put a single project by a U.S. organization can make safe water a reality for thousands of people.
3)Support nonprofit water organizations
Numerous U.S.-based nonprofits work skillfully abroad in community-led projects related to drinking water and sanitation. Like the sample of non-profits noted as follows, some organizations are large, other small-scale, some operate worldwide, others are devoted to certain areas in Africa, Asia, or Latin America. Support them generously.
1. The three facts presented in the passage are used to illustrate that________.
A. poverty can result in water-borne diseases
B. people have no access to clean drinking water
C. women’s rights are denied in some developing countries
D. safe drinking water should be a primary concern
2. The intended readers of the passage are________.
A.  Americans               
B. overseas sponsors
C.  Congressmen   
D .  U.S.-based water organizations
3. The main purpose of the passage is to call on people to _________.
A. get rid of water-related diseases in developing countries
B. donate money to people short of water through religious groups
C. fight against the worldwide water shortage and sanitation problem
D. take joint action in support of some nonprofit water organizations
4. What information will probably be provided following the last paragraph?
A. A variety of companies and their worldwide operation.
B. A list of nonprofit water organizations to make contact with.
C. Some ways to get financial aids from U.S. Congress.
D. A few water resources exploited by some world-famous organizations.

In June, 2007, a group of students from eight high schools in Winnipeg, the capital of Canada’s Manitoba province, will begin test-launching (試發(fā)射) a satellite the size of a Rubik’s cube.
The one-kilogram Win-Cub satellite, named for its home city and its shape, will be put into low orbit. Once in space, it can perform for a few months or up to several years, communicating information that could help find the signs of earthquakes.
There are 80 similar satellite projects worldwide, but this is the first high-school based program of its kind in Canada. 30 Manitoba high school students are having a hand in designing and building the satellite, in cooperation with aerospace (航空航天的) experts and 10 students from the University of Manitoba, and with support from two other organizations.
The Win-Cube project is not something that goes on a piece of paper; it is real-world engineering, allowing high school students to have an opportunity to learn more about the exciting world of engineering through their participation in this challenging program. It is also taken as a wonderful example of the unique partnerships within Manitoba. Designing, building and launching a satellite with high-school participation will bring this world-class educational project into reality and Manitoba closer to space
“These Manitoba high school students deserve congratulations for their enthusiasm, innovation (創(chuàng)新), and a strong love for discovery,” said Education, Citizenship and Youth Minister Peter Bjomson. “We want to make science more relevant, interesting and attractive to high school students by showing them how classroom studies can relate to practical experience in the workplace or, in this case, in space,” Bjomson added. 
The Win-Cube program is mainly named at inspiring a strong desire for discovery on the part of the students. It also shows Manitoba’s devotion to research and innovation and the development of a skilled workforce—all important drivers of knowledge-based economic growth.

Most of us are used to seasons. Each year, spring follows winter, which follows autumn, which follows summer, which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience.
Between 65,000 and 35,000 years ago, the planet was much colder than it is now. During that time the temperature also changed a lot, with periods of warming and cooling. Ice melted during the warm periods, which made sea levels rise. Water froze again during the cold periods.
A new study from Switzerland sheds light on where ice sheets melted during the ice age.
It now seems that the ice melted at both ends of the earth, rather than just in either northern or southern areas. This surprised the researchers from the University of Bern.
Scientists have long assumed(認為) that most of the ice that melted was in the Northern hemisphere(半球) during the 30,000-year-long ice age. That belief was held because the North Pole is surrounded by land, while the South Pole is surrounded by the Antarctic Ocean. It is easier for ice sheets to grow on land. If surrounded by sea, the ice can easily just slip to the ocean instead of building up.
The researchers used a computer model to look at the ways the ice could melt and how it might affect sea levels. They compared these results to evidence(跡象) of how temperatures and currents actually changed during that time.
The model showed that if it was only in the Northern hemisphere that ice melted, there would be a bigger effect on ocean currents(洋流) and sea temperatures than what actually happened. Studies suggest that melting just in the Southern hemisphere would have been impossible, too.
The only reasonable conclusion, the scientists could make, was that the ice melted equally in the North and the South.
It is still a mystery(謎) as to what caused the temperature changes that caused the ice to melt.
72. We can learn from the text that _____.
A.we have experienced temperature cycles since they began
B.what caused ice to melt is still unknown
C. the planet was much colder than it is now between 65,000 and 35,000 years ago, during which time temperature hardly changed
D. before the new study, scientists long believed that ice melted just in either northern or southern areas
73. The underlined phrase "sheds light on" (in Paragraph 3) can be replaced by _____.
A. throws doubts on B. beats down on C. makes it clear D. makes light of
74. The first two paragraphs were written _____.
A. to lead up to the subject that ice melted during the 30,000-year-long ice age
B. to describe what the weather was like during the ice age
C. to compare climate nowadays with that of the ice age
D. to explain what a temperature cycle is
75. Which of the following best shows the relationship between ice, ocean currents and temperatures according to the text?
A. Ice can easily slip into the ocean.
B. Temperature and currents changed as a result of ice melting.
C. Temperature changes lead to ice melting or water freezing, which in turn has an effect on ocean currents and temperature.
D. Ice melted and then froze again due to temperature.
