Thirteen-year-old Madison Williams was studying in her bedroom when Leigh Williams, her mother, told her that a little boy fell into a septic tank(化粪池）and no one could reach him.
Madison and Leigh ran to a neighbor's yard, where they found the boy's worried mother and other adults surrounding the tank opening. It stuck out a few inches above the ground and was 11 inches in width-slightly wider than a basketball-with a hatch(盖子)that had been moved unnoticed. The two-year-old boy had slipped in and was drowning in four feet of waste water inside the eight-feet-deep tank.
Madison surveyed the situation. She was the only one who could fit through the small hole. Without hesitation, she told the adults, "Lower me in. Inside, the tank was dark, and the air was smelly . In the process , she jammed her left wrist against a hidden pole , injuring the muscles in her wrist so severely that the hand was left useless.
Rather than tending to her injury ,Madison tried to feel the underwater boy. Minutes went by before she saw the outline of his foot. Madison shot her good hand out and grasped
the foot tightly "Pull me up!" she shouted. Then, ten minutes after Madison had entered the tank, she and the boy were lifted out.
But the boy wasn't out of trouble. He had lacked Oxygen long enough that he wasn't breathing. He was placed on his side, and an adult hit him hard on the back. It was only when Madison heard him cry that she knew he was all right . It took Madison longer to recover than the boy, who was taken to hospital and left hospital that same night .She, however, experienced months of painful treatment, for the injury that she had postponed tending was more severe, which, says neighbor Mary Holley, made the girl's actions all the more impressive.

B. The boy was curious about the unknown.
C. The hatch was not in the correct position.
D. The tank opening stood out on the ground.

If you go to any college in the United States, you will find most students carrying the same items：books, laptops, cell phones and their official school identification cards, or IDs. These small plastic cards do more than showing the names and pictures of students.
In recent years, IDs in some colleges can also buy things. The schools enter into agreements with banks so students can link their cards to private financial accounts. This way, students can use their cards to pay for things like food on campus and school supplies.
In other words, their IDs become debit cards(借记卡）. However, new research suggests that the way these card programs operate can harm students.
The U.S. Public Interest Research Group(U.S. PIRG) aims to use research to support and protect people's financial interests. The organization has been looking into agreements between colleges and banks for several years.This April, Kaitlyn Vitez, higher education campaign director for U.S. PIRG, released their latest findings."Students with campus debit cards paid over $ 24 million in fees during the last contract year. For example, students may be charged fees if they use another bank to withdraw money. Or, they may be charged fees if they spend more money than they have in their bank accounts , " she said . " Any large fee can create unexpected problems for students , however , banks do not make possible fees clear enough to students."
U.S.PIRG noted that some banks pay colleges for permission to advertise their debit card programs on campus. The advertising can appear to be part of official school programmes and students may feel pushed towards opening accounts.U.S.PIRG also found a connection between colleges with paid agreements and student fees. Students at colleges that received money from banks ended up paying up to 2.3 times more than students at colleges with unpaid agreements. U.S. PIRG contacted several of the colleges in their latest research, yet they seem not to give satisfying comments.
28. What is the second paragraph mainly about ?
A. Potential harm of IDs.
B. Additional use of IDs.
C. Students consuming habits.
D. Students' financial condition.
29. What does the PIRG study find?
A. All banks pay for their bank card ads on campus.
B. Campus debit cards present high fees for students.
C. Many students like to use debit cards at college.
D. Colleges have signed illegal agreements with banks.
30. What do Kaitlyn Vitez's words imply?
A. Colleges benefit a lot from working with banks.
B. Most students fall into heavy debts at college.
C. Banks give away students' financial privacy somehow.
D. Students lack enough information on their campus debit cards.
31. What will the author probably talk about in the following paragraph ?
A. Solutions to the phenomenon.
B. Future of school IDs.
C. Details of debit card programs.
D. Response of some schools.
D
Wind farms have been considered as the way to fight global warming, but a new study suggests they could actually heat the planet up.
The study found that the US would get warmer if the number of turbines(涡轮机）were increased markedly. Researchers say they'll require much more land than previously thought, needing five to 20 times more space than earlier studies have suggested. And winds created by vast fields of turbines could mix warm and cool air, which makes the surface quite warm .
Despite the potential drawbacks, however, the researchers argue wind energy still makes more sense for the environment than fossil fuels. Study coauthor and Harvard University scientist Professor David Keith argued that, when it comes to energy production, there is no free lunch. "Wind beats coal by any environmental measure, but that doesn't mean that its effects can be ignored. We must use fewer fossil fuels to stop carbon production. In doing so, we must make choices between various low-carbon technologies , all of which have some environmental effects , " he said.
More than ten previous studies have now observed local warming caused by US wind farms. Researchers suggested that solar power offers a less damaging energy source in the fight against climate change. In terms of temperature difference per unit of energy generation, solar power has about 10 times less effect than wind, and the solar power energy is mature in a wide range of fields. But there are other considerations. For example, solar farms are dense(密集的）, while the land between wind turbines can be co-used for agriculture.
Tidal power is an environmentally-friendly energy source. In addition to being a renewable energy, it does not give off any climate gases and does not take up a lot of space . However , there are currently very few examples from real tidal power plants and their effects on the environment. Also, it is important to realize that the methods for generating electricity from tidal energy are relatively new technologies. It is projected that tidal power will be commercially profitable within2030 with better technology and larger scales.
32. What is the purpose of the text?
A. To introduce a study finding.
B. To discuss the global warming problem.
C. To prove the benefits of wind farms.
D. To call attention to environmental protection.
33. What is paragraph 2 mainly about ?
A. The effects of global warming.
B. The reason for using wind energy.
C. The disadvantages of wind farms.
D. The working principle of wind farms.
34. What do Professor David Keith's words suggest?
A. Producing energy is easier than before.
B. Consuming energy damages the environment.
C. Burning coal should be totally stopped.
D. Developing low-carbon technologies is hard.
35. Which is recommended considering the environment and practical use?
A. Wind energy.
B. Fossil fuel.
C. Tidal power.
D. Solar energy.

Learning a new language can be tough, and there is no magical way to go about it. 36 Know your learning style. This is the single most important thing you need to know when starting to learn a language . 37 You will need to figure out if you learn best through repetition, through writing down or listening to a native speaker.
Learn pronunciation. 38 Just ask a Polish person how to pronounce the letters"cz".
It will help to learn IPA, the International Phonetic Alphabet, as most dictionaries use
it. Besides, the Foreign Service Institute offers free online language learning materials,
which include audio recordings that help with learning pronunciation.
39 This is probably the most important part of the language besides the vocabulary. "Paul want Mary go store" may communicate an idea, but it is not at all correct English.
If you do not pay attention to grammar, you can sound equally incomprehensible in another language.
Memorize 30 words and phrases each day. Within 90 days this means you will have memorized
about 80% of the language. Memorization is half the battle and there are many different
ways to memorize.
Practice the alphabet. Especially if you are learning a language which operates in a different alphabetical system, you will need to know what the letters look like and how they operate .
40 In doing so , your brain will have an easy path to remembering the letter and the sound that accompanies it .
A. Pay attention to grammar.
B. Start with the most common words.
C. Therefore, there are really no secrets or shortcuts.
D. Try associating images with each letter and sound.
E. Everyone learns differently, especially when it comes to language.
F. Nevertheless, with certain techniques you will be fluent in no time.
G. Even if a language has the same alphabet as yours, the pronunciation is not always
the same.
