1 . Earth is far more alive than we previously thought, according to “deep life” studies that reveal a rich underground ecosystem beneath our feet that is almost twice the size of all the world’s oceans. Despite extreme heat, no light and intense pressure, scientists estimate it has between 15 billion and 23 billion tonnes of microorganisms. “It’s like finding a whole new reservoir (储藏) of life on Earth,” said Karen Lloyd an associate professor at the University of Tennessee.
Results suggest 70 percent of Earth’s bacteria and archaea exist in the subsurface. One organism found 2.5 kilometers below the surface has been buried for millions of years and may not rely at all on energy from the sun. Also, the methanogen (产甲烷菌) has found a way to create methane in this environment, which the methanogen may not use to reproduce or divide, but use to replace or repair broken parts. Lengths of their lives were completely different. Some microorganisms have been alive for thousands of years, barely moving except with shifts in earthquakes or eruptions. They’re just active inside, with less energy than people thought possible to support life.
The team consists of 1,200 scientists from 52 countries in disciplines ranging from geology and microbiology to chemistry and physics. A year before the conclusion of their study, they will present the findings before the American Geophysical Union’s annual meeting opens this week, which they say are made possible by technical advances on drills and microscopes.
The scientists have been wondering about the point beyond which life cannot exist, but the deeper they dig, the more life they find. There is a temperature maximum—currently 122℃—but they believe this record will be broken if they keep exploring and developing more advanced instruments.
Questions remain, including how the microbes interact with chemical processes, and what this might reveal about how life and Earth coevolved.

3 . Since 2001, robotic tools have revolutionized the practice of surgery. They have greatly reduced the stress and physical demands normally placed on surgeons and have made certain procedures possible.
One example is “keyhole surgery”, or minimally invasive (微创) surgery, which normally requires surgeons to stand at awkward angles and make difficult movements with their hands to make a cut inside the patient. But in June 2022, surgeon James Ansell used 3D glasses and two sticks to control four robotic arms to perform a procedure to remove a cancerous tumor. “My colleague said... that this feels like cheating,” Ansell said to The Guardian.
Another area of surgery that has had major technological breakthroughs in recent years is telesurgery. Normally, telesurgery relies on a wired connection due to concerns of harming the patient should a wireless connection drop during surgery, but China made several advancements in wireless telesurgery based on 5G technology.
China achieved the first 5G-based remote operation in March 2019 involving a brain surgery procedure between a surgeon in Sanya and a patient in Beijing, a distance totaling nearly 3,000 kilometers. More recently, a team of surgeons successfully completed remote micron-level eye surgery on rabbits located in a different city. The rabbits were at the Sun Yat-sen University in Guangzhbù, Guangdon g province, whereas the surgical team who operated on them via a 5G robot were at the Hainan Eye Hospital in Haikou, Hainan province.
Looking to the future, people hope that remote surgery could become commonplace to help heal injured soldiers on the battlefield while keeping surgeons at a safe distance. Some even believe that robotic systems, combined with AI, could one day exceed human surgeons.
But, given current technological limitations and the high costs of these robots which can cost millions of dollars, the complete robot takeover of surgery may still be a while off.

5 . Researchers at the University of Massachusetts Amherst (UMass Amherst) recently announced that they have figured out how to engineer a biofilm (生物膜) that harvests the energy in evaporation (蒸发) and changes it to electricity. This biofilm, which was announced in Nature Communications, has the potential to revolutionize the world of wearable electronics, powering everything from personal medical sensors to personal electronics.
“This is a very exciting technology, says Liu Xiaomeng, a graduate student in electrical and computer engineering in UMass Amherst’s College of Engineering and the paper’s lead author. “It generates real green energy, and unlike other so-called ‘green-energy’ sources, its production is totally green.”
That is because this biofilm — which is a sheet of bacterial cells and as thin as a sheet of paper — is produced naturally by an engineered version of the bacterium Geobacter sulfurreducens. G sulfurreducens is known to produce electricity and has been used previously in “microbial batteries” to power electrical equipment. But such batteries require that G sulfurreducens be properly cared for and fed a constant diet. By contrast, this new biofilm, which can supply as much energy as a comparably sized battery, works continuously, because it is dead. And because it is dead, it doesn’t need to be fed.
The secret behind this new biofilm is that it makes energy from the moisture (水分) on your skin. While we daily read stories about solar power, at least 50% of the solar energy reaching the earth goes toward evaporating water. “This is a huge, undiscovered source of energy,” says Yao Jun, professor of electrical and computer engineering at UMass Amherst, and the paper’s one senior author. Since the surface of our skin is constantly moist with sweat, the biofilm can “plug into” it and change the energy locked in evaporation into sufficient energy to power small equipment. “Our next step is to increase the size of our film to power more intelligent wearable electronics,” says Yao, and Liu points out that one of the goals is to power entire electronic systems, rather than single equipment.
1. Which of the following can biofilm do according to the first paragraph?A.Update wearable electronics. |
B.Get power from evaporation. |
C.Supply energy to microbial batteries. |
D.Transform the way of generating electricity. |
A.It is comparatively thinner. |
B.It is environmentally friendly. |
C.It adopts a rare energy source. |
D.It decreases the cost in usage. |
A.By interacting with solar power. |
B.By making electricity out of sweat. |
C.By gaining energy from electronic system. |
D.By employing water to generate electricity. |

6 . The first time you start to read a poem, you must relax and read through it without concentrating on its meaning. Imagine you are meeting a person for the first time. You will just observe him and listen to his voice, as well as watch his shapes or movements, but you have not yet known what he is all about. Likewise, you may enjoy the sound, rhythms, or wording, and form some first impressions about a poem.
On your second reading, you should concentrate more on the general meaning of the poem. This time, you will want to compare your feelings about the poem by now with how you felt before. Are they the same? What is different and why?
Your third reading will focus more on details: the words, phrases, or images. Looking up any unfamiliar words in a dictionary so that you can gain a more accurate understanding. Using the example given above about meeting someone, his image will change gradually and slightly as you meet and learn more about him. Therefore, in your additional readings, it is a good idea to compare your understanding each time with the understanding before.
A helpful approach to further understanding a poem is to summarize it in your own words. Compare your version of understanding with those of others reading the same poem, and listen to how they form such opinions. Remember, however, that there is no exact or right meaning for a poem, as most poets have admitted they themselves are not exactly sure what they meant when writing certain lines or phrases; they have even been heard to say on occasion that sometimes words just seem to “drop from heaven” and land on the page. That is what awakening the imagination is all about. If you are lucky, and if you practice enough, magical things may happen when you write and you may be able to produce a beautiful poem or other work of art yourself.
1. Why does the author give the example of “meeting a person” ?A.To arouse readers’ interest | B.To support his argument |
C.To offer some advice | D.To interpret his point |
A.General meaning. | B.Rhythm beauty. |
C.Deeper meaning. | D.Poetic structure. |
A.Poets themselves don’t understand their poems. |
B.Beautiful poems drop from heaven occasionally. |
C.Poetic meanings are open to different explanations. |
D.Writing a summary helps understand a poem. |
A.Inspiration and hard work help create great poems. |
B.Poetry is an expression of one’s will in words. |
C.Practice and patience make a man perfect. |
D.Luck marches with those who give their very best. |
7 . I was 6 years old when my father told me we were leaving the Big Apple Circus (马戏团). Until that point, I had spent most of my life on the circus lot, playing with the other circus kids. The circus, by its nature, is one that has a loose structure. So the early years after my leaving the circus to sit in a classroom all day felt more like a prison.
But years later, I found areas that interested me. I took the skills I had learned from being onstage and applied them to broadcasting. And so when Boston’s news station WBUR offered me a job out of college, I jumped at the chance. Along the way, I found I really enjoyed the work. I became WBUR’s news reporter. The flexibility and adaptability I’d learned in the circus as a child helped me do my job naturally and easily in a stressful situation — whether it was a destructive tornado outside Boston, or the Boston Marathon bombings of 2013.
But then a serious infectious disease appeared. Suddenly, for the first time in my adult life, I went for a year without doing any shows. But it became clear to me that performing was what I truly wanted. For me, the circus symbolizes who I am. And stages have always been where I’ve felt the most free. Some people get nervous before they go onstage, but by assuming (扮演) the character of Jacques ze Whipper and drawing a stupid moustache on my face, all my social anxiety disappears.
Circus performances go beyond age, socioeconomic status (地位), and even language. It’s the type of performance where you can go anywhere in the world to entertain anyone — help anyone forget their troubles for 5, 10, and even 30 minutes. And most importantly, for me, it means coming home.

B.To stress the value of performing. |
C.To share his personal experiences in a circus. |
D.To discuss the problem of choosing a job. |
