Research has shown that music has an important effect on one’s body and psyche (心灵). In fact, there is a growing field of health care known as music therapy(治疗), which uses music to treat diseases. Even hospitals are beginning to use music therapy. This is not surprising, as music affects the body and mind in many powerful ways.
Research has shown that quick music can make a person feel more alert（警觉戒备）, while slow music can produce a calm, deep thinking state. Also, research has found that music can change brainwave activity levels. This can help the brain to change speeds more easily on its own as needed, which means that music can bring lasting benefits to your state of mind, even after you’ve stopped listening.
Breathing and heart rates can also be influenced by music. This can mean slower breathing, slower heart rate. This is why music and music therapy can help reduce the damaging effects of long-term stress, greatly promoting (促进) not only relaxation, but health.
Music can also be used to bring about a more positive state of mind by helping to keep worries away. Music has also been found to bring many other benefits, such as lowering blood pressure and reducing the risk of strokes（中风）. It is no surprise that so many people are considering music as an important tool to help the body become or stay healthy.What can we infer about music therapy(治疗)?
| A．It is a type of music. |
| B．It is a research about music. |
| C．It is a kind of musical effect on diseases. |
| D．It is the use of music method to help treat diseases. |
According to the second paragraph, we can know that ________.
| A．music with different speeds has different effects |
| B．quick music is not good for one’s health |
| C．slow music can help one to think more calmly and slowly |
| D．music will have less benefit after one stops listening |
The reason why music can help deal with stress is that ________.
| A．it is used by many hospitals |
| B．it can help change brainwaves |
| C．it does good to breathing and heart rates |
| D．it can bring a more positive state of mind |

What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to? The good news is that we can. In fact, we are swimming in it--- literally.
Hydrogen is one of the building blocks of the universe. Our own sun is basically a big, dense cloud of the stuff. And hydrogen can be used to create electricity for power, heat and light.
The problem is that hydrogen is everywhere and nowhere at the same time. It does not exist as a material on its own, but is always part of something else. So it has to be separated before it can be used.
Most commercial hydrogen in use now is created from natural gas. As oil will start to run out in around the year 2030, it makes sense to produce as much hydrogen as possible as soon as we can. But natural gas supplies will also begin to run out soon after. Another source is needed.
Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen “fuel cells” for computers and mobile phones have already come on to the market. Auto companies have also invested over US $2 billion in the production of hydrogen fuelled cars.
The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution. The only by-product of creating hydrogen is pure drinking water--- something that is very scarce in many parts of the world. But that is not where the good news ends. Once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth’s population that has no electricity.
And electricity creates wealth. In South Africa over the last decade there has been a large programme of electrification. Thanks to the programme, people do not have to spend their days looking firewood to burn for heat. And with electric light, they can work long into the night.
Some scientists see radical changes in the way the human race co-operates. Hydrogen creates electricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web,” which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source.
Like all dreams of the future, it seems very far away. But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to end oil dependency and spend more time and money on hydrogen resource. So maybe the threat of war is not a completely bad thing for the future of the human race. What does the underlined word “it” in the last but one paragraph refer to?
| A．wealth | B．hydrogen | C．electricity | D．fuel |
What is the problem with using hydrogen as energy?
| A．It has by-products. |
| B．It has to be separated from other materials. |
| C．It will make energy too cheap. |
| D．It is too far away from us. |
Why does the author give the example in the last but one paragraph ?
| A．To tell us that we produce energy while using hydrogen power. |
| B．To tell us that hydrogen power does not produce pollution. |
| C．To show hydrogen power can stop war. |
| D．To show hydrogen power is cheap. |
What is the author’s attitude about the future?
| A．skeptical | B．negative | C．indifferent | D．positive |
What is the passage mainly about?
| A．war and energy | B．the future of hydrogen as an energy resource |
| C．the disadvantages of oil | D．How to end war |
Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陈代谢)becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious(恶性的)circle in its tracks, people need to consume food and supplements that will neutralize (使…中和) the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.What is the main purpose of this passage?
| A．To advocate eating more raw and whole foods. |
| B．To tell the differences between raw and processed foods. |
| C．To inform people of the harm of processed foods. |
| D．To warn people of the problem of obesity. |
It can be inferred from Para. 2 that ________.
| A．it is essential for people to protect their vital organs |
| B．foods with natural enzymes help people keep fit |
| C．we’d better be cautious about raw and whole foods |
| D．giving up cooked and refined foods is a new lifestyle |
Processed foods are unhealthy because they __________.
| A．destroy body’s cells | B．are difficult to digest |

Americans are buying more products and services than ever before through the Internet, and the popularity of online sales is likely to spread to other countries. Online sales now represent as much as one-tenth of all retail(零售) sales in the United States，which has led traditional stores to seek new ways to keep their customers loyal.
Lynne Shaner used the Internet to buy everything she needed for her wedding and holiday gifts for her husband. Other than food, 90 percent of her purchases(购买的东西) were made on her home computer. “I find that, by being able to go online and opt for the things that I need to select and have them delivered to me right at my doorstep, I’m free from all the driving, all the crowds, all the noise, and I usually get a better selection.”
There are a lot of people like her. Experts say American online shopping hit records in both November and December. Fifty-seven percent of Americans have bought something electronically. Store owners worry that this growing amount of online sales will hurt their business. Cornell University marketing professor Ed McLaughlin says, “They should be worried. Anything that can move online will be sold online. And it's just a matter of time. However, traditional stores can keep their customers by selling goods like clothing, which buyers may want to see and try on before purchasing. The stores could also offer things that are difficult to ship. ”
Bill Martin, whose business helps stores learn about their customers, says, “Traditional stores offer a social experience that some people enjoy. There is still a lot of emotion in the buying decision that takes place, and you can't always get that on-line. It's a rather cold process. Traditional stores can provide goods for buyers more quickly than online stores. And some retailers are using websites to persuade people to visit their stores. ”
While online shopping worries some business owners, the only worry for delivery services like FedEx and UPS is keeping up with the number of packages. UPS Manager Dana Kline says her company is very busy at this time of year. UPS is so busy that it has filled 55,000 temporary worker positions during the holiday season.According to Lynne Shaner, shopping online ________.
| A．helps choose things she needs most |
| B．will replace traditional shopping soon |
| C．offer many benefits to customers |
| D．seldom provides a better selection |
What does the underlined phrase “opt for” in the second paragraph mean?
| A．choose | B．sell | C．design | D．purchase |
Professor Ed McLaughlin thinks that _________.
| A．online shopping has little effect on traditional stores |
| B．it is time for store owners to be anxious about their business |
| C．traditional stores can do nothing to stop challenges from online shopping |
| D．traditional stores should sell more things that are difficult to ship |
What can we know from the fourth paragraph?
| A．Online sales fail to offer customers sense of emotion. |
| B．Customers enjoy social experience when shopping online. |
| C．Traditional stores can help customers decide what to buy. |
| D．Customers can buy goods more quickly after visiting websites. |

| B．business owners are concerned about delivery services |
| C．FedEx is keeping up with UPS on the number of packages |
| D．delivery services are facing more and more pressure from online sales |
According to a study by SallieMae, 84 percent of undergraduate students have credit cards, and by the time they are seniors, they have accumulated US＄4,100 in debt, on top of whatever student loans they may have taken out.
Credit cards are the most convenient form of payment, and they are aggressively marketed to college students. Reportedly, a typical college student carries 4.6 credit cards and US＄3,173 in credit card debt.
Credit cards seem to be a fact of life, not just student life. In the long term, using a credit card properly and paying off the balance can help establish a card history and increase your credit score, which will come in handy when you need an important loan, for a house or car, for example. Your credit score can affect even unrelated things like insurance rates. Credit cards also offer more protection for users than debit cards （借记卡）.Under federal law, the credit card holder is only responsible for the first US＄50 in fraudulent(欺诈的)purchases in cases of theft or loss. However, debit card users are responsible for the first US＄500.
SallieMae found some good news in the fact that two thirds of students had discussed credit issues with their parents, but 84 percent said they needed more information. Those who didn’t get any guidance were more likely to be surprised when they found out how much they owed.
While credit cards offer the easiest access to money, they make it easy to live outside your means. Less than a fifth of students surveyed paid off their balance every month, and carrying a balance brings finance charges, sometimes at a very high interest rates.
SallieMae found that almost 40 percent of students chose their first credit card based on direct mail, which is probably why students get credit card offers in the mail. But when the credit card offers flow in, be sure that you read the fine print. Offers of low or no interest rates can disappear, leaving you a debt that climbs beyond your ability to pay it off. What does the first paragraph imply?
| A．Most of the senior students are shocked to see how much they owed. |
| B．Students can only take out loans from credit cards. |
| C．Most of students’ loans come from credit cards. |
| D．Credit cards have a bad effect on college students. |
The underlined part “come in handy” in the third paragraph probably means “_______”.
| A．bring trouble | B．make mistakes | C．be important | D．be useful |
According to SallieMae, what is the possible reason why students get so many credit card offers in the mail?
| A．Many students’ first credit card is based on direct mail. |
| B．It costs the banks little to mail out credit cards. |
| C．Students don’t like to go to the bank to open a credit card account. |
| D．Banks have no other way to let students use their credit cards. |
What is the theme of the third paragraph?
| A．The advantages of using debit cards. |
| B．The similarities between credit cards and debit cards. |
| C．The advantages of using credit cards. |
| D．Credit cards are the most convenient form of payment. |
