1 . 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. |

3 . 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 can be concluded from the last paragraph?| A．More trees should be planted in dry regions. |
| B．More methods should be adopted to address the climate crisis. |
| C．Fields of solar panels should be set up everywhere on the earth. |
| D．Building solar panels and planting trees should be effectively combined. |
4 . Four Wonderful Hotels in India
Vythiri Resort, Lakkidi, Kerala
Vythiri Resort has five tree houses, including the one that’s child-friendly and buried in the jungle.

5 . 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.
What happened after Jacqueline Wang finished her performance?| A．Her teacher played a piece of music to compete against her. |
| B．She got her performance reviewed on the Spirio|r. |
| C．She was asked to comment on her performance. |
| D．Her teacher instructed her to improve her skills. |
6 . 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 underlined word “this” in the third paragraph means “ ______”.| A．the understanding of a great deal of what goes on around you |
| B．the understanding of basic science and mathematics |
| C．being able to make good decisions in life |
| D．good training in body and mind |
7 . Now let us look at how we read. When we read a printed text, our eyes move across a page in short, rough movement. We recognize words usually when our eyes are still when they fixate (凝视). Each time they fixate, we see a group of words. This is known as the recognition span or the visual span. The length of time of which the eyes stop -the duration of the fixation — varies considerably from person to person. It also varies within one person according to his purpose in reading and his familiarity with the text. Furthermore, it can be affected by such factors as lighting and tiredness.
Unfortunately, in the past, many reading improvement courses have concentrated too much on how our eyes move across the printed page. As a result of this misleading emphasis on the purely visual aspects of reading, numerous exercises have been devised to train the eyes to see more words at one fixation. For instance, in some exercises, words are flashed on to a screen for, say, a tenth or a twentieth of a second. One of the exercises has required students to fix their eyes on some central point, taking in the words on either side. Such word patterns are often constructed in the shape of rather steep pyramids so the reader takes in more and more words at each successive fixation. All these exercises are very clever, but it’s one thing to improve a person’s ability to see words and quite another thing to improve his ability to read a text efficiently. Reading requires the ability to understand the relationship between words. Consequently, for these reasons, many experts have now begun to question the usefulness of eye training, especially since any approach which trains a person to read isolated words and phrases would seem unlikely to help him in reading a continuous text.
What is the writer’s attitude in writing this passage?| A．critical | B．neutral | C．pessimistic | D．optimistic |

9 . PCs are no longer the only things that can be hacked（非法侵入）. Anything with an electronic pulse, including cars, TVs and refrigerators, is now a target for hackers. Here are several strangest hacks that show where the future is headed:
Remote-controlling a car – Well-known security researcher Charlie Miller is able to control a car by accessing the automotive computer. In 2011, a security company figured out how to unlock a car and start it just by texting and back in 2010, someone hacked into100 cars in Texas, causing them to honk（鸣响）uncontrollably before he remotely disabled them.
Cyber Murder – In Season 2 of Show Time’s homeland series, hackers kill the US Vice President by hacking his pacemaker（心脏起搏器）. Typical Hollywood B. S., right? No. It could actually happen. Well-known security researcher Barnaby Jack, who sadly passed away in July at the age of 35, had been prepared to demonstrate at Back Hat how to hack a pacemaker over Wi-Fi. The attack could kill a person by giving the pacemaker a high-voltage shock.
Spy Phone – By now, more people are becoming aware of the potential for a phone to be hacked. But what many fail to realize is the awesome potential of a smart phone to affect you, it has been hacked.
When Your TV Watches You – This type of hack makes it possible to monitor people in their homes via the internet. Smart TVs aren’t that common yet, but in the next few years they could become an important part of the living room, so watch out.
According to Cyber Murder, we know that Barnaby Jack ________.| A．was killed by the attack over Wi-Fi |
| B．was a well-known actor and researcher |
| C．researched how to hack a pacemaker over Wi-Fi |
| D．died at Black Hat when hacking a pacemaker |
10 . Examining the classroom practices of National Teacher of the Year winners and finalists, the study, by Michigan State University scholars, suggests successful educators aren’t afraid to push the boundaries by adding real world, cross-disciplinary（跨学科的）themes into their lessons.
The study, published online in the journal Teachers College Record, is one of the first in depth investigations of how teachers use creativity in the classroom.
“The best teachers are taking their own creative interests – from rap music to cooking to kickboxing – and are finding ways to include these into the curriculum,” said Danah Henriksen, lead author of the study. “They’re bringing together different subject matters and finding areas of connections so students can learn both in interesting ways.”
America’s test-driven educational policy, Henriksen argues, has impeded creativity in teaching and learning. Many teachers today struggle to balance high-stakes（高风险）testing and responsibility to act flexibly and independently in their classrooms.
“I think that there’s a lot of fear.” one of the award-winning teachers says in the study, “And when teachers are teaching in fear, they take few risks, for they have to consider exams and academic performance.”
The findings have major implications（含意）for teaching and learning. Teachers’ unique creative interests should be brought into classroom lessons, along with arts and music across varied academic content. Teacher education programs and professiona1 development courses should include a focus on real world. Administrators and policymakers should support opportunities for teachers to take creative and intellectua1 risks in their work.
“If we want teachers to be creative, we need to provide them with opportunities to bring those outside interests into their professional life,” said Mishra, study co-author and MSU professor of educational psychology and educational technology. “The point is to find what works for you, what is your passion and interest and how can you put that into what your students are learning. Finally, we teach who we are. That’s the most powerful finding.”
What does the underlined word “impeded” in paragraph 4 mean?| A．admitted. |
