21、In 2016, designer Liz Ciokajlo received a task from the Museum of Modern Art (Moma) in New York: revisit the Moon Boot, a fluffy-looking snowshoe inspired by the footwear used by the Apollo astronauts.
Launched in 1972 at the height of the lunar missions, the Moon Boot is an icon of the 20th Century’s “plastic age” and the museum administrators wanted a new take on it.
Ciokajlo set out to reimagine it. She knew only a biomaterial would work in a “post-plastic age”, but the designer also wanted a new destination to inspire it. Our generation’s space travel obsession is not the Moon, she thought, but the red planet Mars. And Mars allows you to really think outside of the box.
The task led her to an amazing biomaterial that had already attracted the attention of engineers innovating m building materials and of top space agencies like NASA and ESA. Her final design, a tall, female, rough-looking boot, can be made on board a spaceship with almost only human sweat and a few fungus spores (真菌孢子), ideal for a seven-month trip to Mars with limited check-in luggage.
This magic biomaterial is mycelium (菌丝体), the vegetative part of the fungus It looks like amass of white thread-like structures, each called hyphae. Collectively, these threads are called mycelium and are the largest part of the fungus.
Mycelium has amazing properties. It is a great recycler, as it feeds off a substrate to create more material, and has the potential of almost limitless growth in the right conditions. It can endure more pressure than conventional concrete without breaking. It is a known insulator and fire-retardant and could even provide radiation protection on space missions.
On Earth it’s currently used to create ceiling panels, leather, packaging materials and building materials, but in outer space it stands out for its architectural potential, says artist and engineer Maurizio Montalti, who has teamed up with Ciokajlo.
For her revisited boot, Ciokajlo wanted to use the human body as the source for some of the building materials and decided to employ sweat. Reusing sweat is not entirely new in space exploration but a novelty approach for footwear. She thinks it might make astronauts feel closer to home during the long journey to Mars.
The design is still hypothetical, because the real boot submitted for Moma and currently in display at the London Design Museum did use mycelium but not human sweat, as their deadline was too tight, but the science checks out.
【1】The sentences “‘Mars has always been a place where you can dream. It is a place where you can reimagine how to live on Earth.’ Ciokajlo says.” w should be put__________.
A. between Para. 1 and Para.2 B. between Para. 2 and Para.3
C. between Para.3 and Para.4 D. between Para. 4 and Para.5
【2】According to the passage, which of the following Doesn’t belong to the characteristics of mycelium?
A. It can be recyclable.
B. It can protect people from radiation.
C. It can grow without limit whatever the condition.
D. Compared with conventional concrete, it can endure more pressure.
【3】Which of the following is TRUE according to the passage?
A. The new design will be used for moon exploration.
B. It will be some time before the new design is put into actual use.
C. Mycelium has been currently widely used, especially in outer space.
D. Human sweat wasn’t used in the design because of some drawbacks.
【4】The author takes a(n) ___________attitude towards the new design.
A. optimistic B. indifferent C. objective D. doubtful
22、Plenty of harvests of corn and other major crops rely on a mysterious phenomenon known as hybrid vigor (杂交活力). When highly naturally-born varieties are crossed, their next generations are taller, hardier, and bear more grain, Researchers report that this vigor is somehow influenced by microbes (微生物) in the soil, perhaps through a plant's immune system .
Charles Darwin was one of the first researchers to describe hybrid vigor. In the early 20th century, biologists began to apply this effect to agriculture by creating naturally-born parent plants that produced hybrid seeds. By the 1940s, almost every farmer in the United States was planting hybrid corn, and the harvests multiplied.
Biologists have proposed several theories about the cause of hybrid vigor, but no definitive explanation has emerged.
Maggie Wagner, plant biologist at the University of Kansas, and her colleagues wondered whether microbes might be it involved. Last year, Wagner and her colleagues found an interesting clue in a field study. They discovered that the leaves and roots of hybrid corn had microbial communities that are different from those living on naturally-born varieties of corn. “Something about being a hybrid makes a plant interact differently with microbes,” Wagner says. It could be that the naturally-born corn's immune systems react more actively to beneficial microbes, compromising their growth. Alternatively, hybrid plants may be better able to defend against weak pathogens (病原体) in the soil.
Wagner says the finding highlights the need for plant growers to match the hybrid crops to the microbial communities with which they live. The findings help scientists realize the importance of understanding the role of soil microbes in making agriculture more productive and sustainable, “This holds great promise.”
【1】How did people use the effect of hybrid vigor in agriculture?
A．By producing naturally-born parent plants that bore hybrid seeds.
B．By creating naturally-born parent lines that produced hybrid vigor.
C．By providing more microbes communities that could produce more seeds.
D．By looking for hybrid parent plants in the field that produced hybrid seeds.
【2】What can we know from paragraph 4?
A．Hybrid plants react worse to weak pathogens in the soil.
B．Wagner connected hybrid vigor with microbial communities.
C．Being naturally-born makes a plant interact differently with microbes.
D．Hybrid corn and naturally-born corn have similar microbial communities.
【3】What effect would Wagner's finding have?
A．Making farmers know what to grow to resist certain diseases
B．Helping scientist realize the importance of spreading soil microbes.
C．Showing the significance of associating soil microbes with specific crops.
D．Highlighting the need for plant growers to find more microbial communities.
【4】What may be the best title for the text?
A．Hybrid corn: a double-edged sword
B．How can farmers grow hybrid crops?
C．Hybrid vigor: a mysterious phenomenon
D．What role do soil microbes play in the harvests of corn?
23、About five weeks ago, I noticed the skin of our pet lizard (蜥蜴)was growing dusty. It worried me. I reported the strange surface on the skin of the lizard to my husband and children the next morning. Seconds later, our lizard emerged from its tank with its old skin flowing behind it.
I didn't think about it much until a morning last week when I knocked my favorite teapot off the table. It burst into hundreds of pieces. As I swept up the mess, I wondered why we had been breaking so many things over the months.
The destruction started three months ago. It was my husband's birthday. He had just lost his job. The uncertainty was starting to wear on us, so I wanted to do something special.
“Let's make a cake for Dad!” I cried.
My kids screamed with joy. We baked, iced and sprinkled for most of the day. Candles on the cake! Balloons on the walls! Flowers on the table!
Two hours before my husband came back home from another job interview, my daughter climbed up to grab a glass vase from a high shelf. It fell and crashed beside the cake. Tiny pieces of glass were everywhere. She sobbed loudly as I threw the cake away. My husband had banana pudding for his birthday.
Three days ago, the light in our living room suddenly went out. After several frustrating hours of unsuccessful attempts to fix it, my husband suggested watching the Michael Jordan documentary (纪录片)series The Last Dance.
The poignancy (酸楚)of Jordan retiring from his beloved basketball to play baseball and what had pushed him to make such a tough decision took me by surprise. As I watched him take off his basketball uniform and replace it with a baseball uniform, I saw him leaving behind the layer that no longer served him, just as our lizard had. Neither of them chose the moment that had transformed them. But they had to live with who they were after everything was different. Just like us. I realized that we have to learn to leave the past behind.
Humans do not shed skin (蜕皮)as easily as other animals. The beginning of change is upsetting. The process is tiring. Damage changes us before we are ready. I see our lizard, raw and nearly new.
Jordan said that no matter how it ends, it starts with hope. With our tender, hopeful skin, that is where we begin.
