A．Results．　　　　　 B．Requirements． C．Advantages． D．Barriers． √ 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 B　[词义猜测题。根据第三段中“The only caveats are that conditions in the container must be kept above 90℃，and the light must remain on the whole time．”可知，caveats指该技术在操作中需要满足的条件或要求，与“Requirements(要求)”含义一致。] 3．What might the follow-up study focus on? A．Speeding the reactions in the liquid． B．Reducing operating costs in the process． C．Raising people's awareness of recycling． D．Increasing the temperatures in the container． √ 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 A　[推理判断题。根据最后一段首句“The researchers acknowledge that the reaction is slow，but also note that it has high output and is simple，easy and inexpensive to conduct．”可推断，后续研究可能针对当前技术“反应慢”的缺点，探索加速反应的方法。] 4．Which of the following serves as the best title for the text? A．The Chemistry of Recycling B．Microplastics：Bad to Worse C．Plastic Recycling's Old Problems D．A Breakthrough：Plastic to Monomers √ 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 D　[标题归纳题。根据第一段中“In a new study，the researchers in Switzerland have developed a way to break down plastics into their monomeric substances，allowing for much easier and cheaper recycling．”及全文对该技术的原理和优势的介绍可知，文章核心是讲述“将塑料分解为单体”这一突破性回收技术。D项“突破：塑料分解为单体”适合用作标题。] B (2025·江西新余二模) We all know cacti (仙人掌) store water—but to survive，they also adjust their flower positions to gain more sunlight or shade，and so much more．Scientists have been copying the resilient plants'methods to help engineer our future． 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 One of the most exciting advancements involves Copiapoa，a genus of cacti with at least 32 species found in the coastal Atacama Desert，the driest nonpolar desert on Earth．These cacti，typically five to six inches wide，can form gray-green bushes that spread out over an area otherwise empty of vegetation． 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 Documented by many scientists，Copiapoas probably survive by“drinking”the salty fog that sweeps in from the sea every morning，as well as the dew—tiny bits of water—that forms on their spines (尖刺) and skin．This has inspired researcher Tegwen Malik from Swansea University to think about whether the dew-collecting process might be reproduced in metal structures． 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 Specifically，Malik took a close look at the one-and-a-quarter-inch spines of Copiapoas and found that their surface has a series of tiny channels that broaden at the base．“This creates a surface roughness that enables dewdrops to move along them even against gravity，”she says． 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 Starting in 2013，she set out to recreate that structure by engineering a flat metal reproduction of the stems and spines of the Copiapoa，which she began testing under a series of different temperatures and humidities．After several years of experiments—testing indoor and outdoor conditions，and with various cooling methods—she finally got it to work．In 2023，Malik published a study showing that the irregular surface was 8 percent more efficient at harvesting dew than a flat sheet used as a baseline． 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 Malik imagines desert homes with water-collecting features to provide clean water in dry regions．“The easiest way could be to place dew-harvesting surfaces on roofs，but you could also have these structures in tents in the desert，”she says．“We truly have hidden treasures in the Copiapoa，and we are only just learning some of their secrets．” 【语篇解读】　本文是一篇说明文。文章介绍了科学家受仙人掌启发，研发出了可以在干旱地区收集露水的金属结构，为干旱地区提供清洁水源。 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 5．What does the underlined word“resilient”mean in paragraph 1?

104 Researchers at Cornell University addressed this question by attaching brain-scanning electrodes and tiny eye-tracking cameras to mice．They monitored the mice as they learned new tasks during the day，such as navigating a maze，and then observed them during sleep．(Fun fact：mice can sleep with their eyes open．) 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 The study revealed two distinct substages during non-rapid eye movement (NREM) sleep，a critical period for memory formation．One substage replayed new memories，coinciding with narrowed pupils．The other involved recalling older memories，marked by widened pupils．These stages alternated rapidly．The team also discovered that during the narrowed pupil stages，blocking sharp-wave ripples (SWRs) limited the mice's ability to remember new information． 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 It is also found that the brain has an intermediate (中间的) period that separates new learning from old knowledge．The results suggest that the brain can multitask distinct cognitive processes during sleep to facilitate continuous learning without interference．It's like new learning，old knowledge，new learning，old knowledge，shifting slowly throughout sleep． 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 The implications of the study are far-reaching：such a non-invasive means of monitoring brain function may help treat memory issues and boost memory，for example．The study also supports the hypothesis (假说) that human brains and computer systems may significantly forget old information．Catastrophic forgetting，known in AI，is an area where machines still lag behind biology．What's more，the findings provide a potential solution for preventing catastrophic interference while enabling memory integration in both biological and artificial neural networks． 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 Despite the many similarities between human and mouse brains，similar studies need to be conducted in humans to verify these results． 【语篇解读】　本文是一篇说明文。文章介绍了康奈尔大学的研究，该研究关注记忆如何被无干扰保存，揭示了非快速眼动睡眠阶段大脑处理新旧记忆的方式及研究意义。 专项练 随堂演练 考点4 考点3 考点2 考点1 考点5 第三讲　词句猜测题 1．What do researchers at Cornell University focus on?
