1 . Seated at the grand piano in MIT’s Killian Hall last fall, first-year student Jacqueline Wang played one piece of Mozart’s music. When she’d finished, Mi-Eun Kim, a pianist and lecturer at MIT, asked her to move to the back of the hall. Kim tapped at an iPad. Suddenly, the music Wang had just played poured forth again from the piano - its keys sinking and rising just as they had with Wang’s fingers on them. Wang stood with a confused expression, taking in a repeat of her own performance.
This unusual lesson took place during a three-week residency (驻留期) of the Steinway Spirio|r, a piano that obtains the data of live performances and offers students new possibilities for studying and experimenting with music.
Wang was one of several participants to have the experience of hearing herself play while watching the data of her performance move up and down across a screen: color-coded rectangles (矩形) indicating the speed and duration of each note, and a moving line charting her use of the damper pedal (阻尼踏板). Wang could even edit her own performance when Kim suggested her rhythmic use of the pedal might be unnecessary. Using the iPad interface to erase the pedaling entirely, they listened to the playback again, the notes gaining new clarity,
For Wang, the session introduced an element she’d never experienced since beginning her piano studies. The visual display of how long each key was played and with what speed gave her a more precise demonstration of the ideas of voicing and evenness.
Playing the piano is one of the most complex activities that humans do with their hands. Some people might think the new technology will replace the pianist. In Kim’s view, that human complexity is complemented by this kind of technical possibility. But it doesn’t mean all of the things that go into learning music will be abandoned. It’s going to be an invaluable third partner: the student, the teacher, and the Spirio | r. It’s going to play a necessary role in lots of musical efforts.

2 . While many of us might long to just sleep through this entire winter, humans, unlike a lot of other mammals - don’t have the capacity to hibernate (冬眠). But researchers think they have found some tell-tale marks on the fossils, which suggests that early humans may have survived the harsh winter by hibernating.
Bears have specialized metabolic (新陈代谢的) processes to protect them from this extended sleep, but sometimes this process doesn’t quite go to plan. For example, hibernators can end up with a host of diseases after hibernation if they don’t get enough food reserves before they go down for the winter. The researchers believe this may have been the circumstance of some human ancestors whose remains with deep cracks in bones were discovered in a Spanish cave called Sima de los Huesos. This deep hole is home to an incredible number of fossils, with archaeologists having discovered thousands of early humans’ skeletal remains that are around 430,000 years old and probably the ancestors of the Sima people or others.
In a paper published in L’Anthropologie, two experts argue that the fossils found in Sima de los Huesos show seasonal variations that suggest that bone growth got interrupted for several months of each year. They suggest these early humans found themselves being in metabolic states that helped them to survive for long periods of time in extremely cold conditions with limited stores of body fat.
The researchers admit the idea “may sound like science fiction”, but they point out that many mammals including primates (灵长类动物)do this. “This suggests that the genetic basis and physiology for such slow metabolism could be preserved in many mammalian species including humans," state Arsuaga and Bartsiokas.
However, Chris Stringer of the Natural History Museum in London pointed out that large mammals such as bears do not actually hibernate, because their large bodies cannot lower their core temperature enough. Instead, they enter a less deep sleep known as torpor. In such a condition, the energy demands of the human-sized brains of the Sima people would have remained very large, creating an additional survival problem for them during torpor.
Why does the author mention the example in Paragraph 2?| A．To explain the special ability of bears. |
| B．To provide the background to the research. |
| C．To show the basis of researchers’ evaluation. |
| D．To discuss a new cause of hibernating disease. |

7 . The green, natural forest absorbs carbon dioxide from the air through photo- synthesis (光合作用). There is another way of dealing with the climate crisis. That is setting up fields of dark-colored solar panels (太阳能电池板), also known as “solar forests”, which replace power stations that use fossil fuels such as coal and gas to make electricity, thus mitigating harmful emissions (排放) of greenhouse gases.
But since they are both relatively dark, they absorb a lot of solar radiation. Some of the energy is used for photosynthesis in natural forests or to produce electricity in “solar forests”, but most returns to the atmosphere, heating it up. Then what would be the more effective land use option in terms of the climate crisis: planting a forest, or building solar panels? This issue has long been debated by decision-makers around the world. Now, we may have an answer, thanks to a new study.
First, the researchers compared the impact of a forest on the climate crisis in a dry area to that of a solar farm in a similar environment. The researchers found that the albedo effect (反射效应) of both of these “forests” was similar, but that the absorption or prevention of carbon emissions was very different. It turns out that it takes 2.5 years for the heat emitted by solar farms to be balanced by the carbon emissions that are avoided, thanks to the energy they produce. In the case of a natural forest of similar size, it would take more than 100 years of photosynthesis to balance its heating effect.
The researchers also studied how the heating-cooling relationship changed in other climates and found that in more humid environments, the heating effect of planting large numbers of trees is smaller. And the break-even point is reached within 15 to 18 years.
“In dry places, building solar forests seems far more effective in addressing the climate crisis. Meanwhile, forests absorb about a third of annual carbon emissions and play a vital role in the global rain cycle, in maintaining biodiversity and in many other environmental and social contexts. Preventing them from being cut down and planting more trees in humid areas are of great significance,” explains one of the researchers in the study.
What is the root cause of the long-running debate over the two types of forests?| A．They cause much damage to the land. |
| B．They result in a serious loss of farmland. |
| C．They contribute to the warming of the atmosphere. |
| D．They lose energy during the absorption of solar radiation. |
8 . Everyone knows you must exercise regularly to keep good health. Indeed, staying physically fit is a big part of our culture. We consider (or rightly so) that healthy people are attractive people. Since most of us want to be attractive, there is no shortage of exercise clubs, training videos, magazines and books offering to help us stay physically fit.
Unfortunately, however, our culture doesn’t place the same emphasis on mental fitness. Although we tend to like men and women with strong, healthy-looking bodies, we don’t have the same degree of respect or attraction for smart, educated, mentally healthy people. This is a pity, because there are great rewards for people who have developed the ability to think well.
If your mind is well trained and flexible, you will be able to understand a great deal of what happens around you. And if you are also well educated-that is, if you understand basic science, mathematics, music, art, literature, history and so on—you will find it much easier to make good decisions throughout your life. Over the long run, this leads to a sense of control over your destiny (命运) and a much better life than otherwise (in another way).
People who are poorly educated or who don’t think well—that is, people who are not mentally fit—see things differently. Their world is controlled by mysterious, often malevolent (恶意的) forces. Such people live within a system they will never master, forced to follow rules they will never understand. Although it may not be obvious, most spend their lives being manipulated (控制) by others. They are told what to do, what to think, how to spend their money, and what they should and should not aspire (渴望) to in life.
In my opinion, if you want to live well, you must be able to use your mind well. For this reason, I want you to be able to concentrate, to solve problems, to understand complex ideas, and to think clearly and quickly. Such skills will make it easier for you to make informed decisions, understand current events, choose good friends, manage your money well, make wise long-term decisions and appreciate music, art and literature.
The key to developing such skills is to enjoy learning, and to have the ability and motivation to teach yourself.
The best title of the passage will most probably be “ ______”.| A．Train Your Body |
| B．Think Hard and Work Hard |
| C．Make Informed Decisions |
| D．Train Your Mind |

10 . A month after Hurricane Katrina, I returned home in New Orleans. There lay my house, reduced to waist-high ruins, smelly and dirty.
Before the trip, I’d had my car fixed. When the office employee of the garage was writing up the bill, she noticed my Louisiana license plate. “You from New Orleans?” she asked. I said I was, “No charge,” she said, and firmly shook her head when I reached for my wallet. The next day I went for a haircut, and the same thing happened.
As my wife was studying in Florida, we decided to move there and tried to find a rental house that we could afford while also paying off a mortgage (抵押贷款) on our ruined house. We looked at many places, but none was satisfactory. We’d begun to accept that we’d have to live in extremely reduced circumstances for a while, when I got a very curious e-mail from a James Kennedy in California. He’d read some pieces I’d written about our sufferings for Slate, the online magazine, and wanted to give us (“no conditions attached”) a new house across the lake from New Orleans.
It sounded too good to be true, but I replied, thanking him for his exceptional generosity, that we had no plans to go back. Then a poet at the University of Florida offered to let his house to me while he went to England on his one-year paid leave. The rent was rather reasonable. I mentioned the poet’s offer to James Kennedy, and the next day he sent a check covering our entire rent for eight months.
Throughout this painful experience, the kindness of strangers has done much to bring back my faith in humanity. It’s almost worth losing your worldly possessions to be reminded that people are really nice when given half a chance.
