（2024·北京·高考真题）The ntin that we live in smene else’s vide game is irresistible t many. Searching the term “simulatin hypthesis” (模拟假说) returns numerus results that debate whether the universe is a cmputer simulatin — a cncept that sme scientists actually take seriusly. Unfrtunately, this is nt a scientific questin. We will prbably never knw whether it’s true. We can, instead, use this idea t advance scientific knwledge.
The 18th-century philspher Kant argued that the universe ultimately cnsists f things-in-themselves that are unknwable. While he held the ntin that bjective reality exists, he said ur mind plays a necessary rle in structuring and shaping ur perceptins. Mdern sciences have revealed that ur perceptual experience f the wrld is the result f many stages f prcessing by sensry systems and cgnitive (认知的) functins in the brain. N ne knws exactly what happens within this black bx. If empirical (实证的) experience fails t reveal reality, reasning wn’t reveal reality either since it relies n cncepts and wrds that are cntingent n ur scial, cultural and psychlgical histries. Again, a black bx.
S, if we accept that the universe is unknwable, we als accept we will never knw if we live in a cmputer simulatin. And then, we can shift ur inquiry frm “Is the universe a cmputer simulatin? ” t “Can we mdel the universe as a cmputer simulatin? ” Mdelling reality is what we d. T facilitate ur cmprehensin f the wrld, we build mdels based n cnceptual metaphrs (隐喻) that are familiar t us. In Newtn’s era, we imagined the universe as a clck. In Einstein’s, we uncvered the standard mdel f particle (粒子) physics.
Nw that we are in the infrmatin age, we have new cncepts such as the cmputer, infrmatin prcessing, virtual reality, and simulatin. Unsurprisingly, these new cncepts inspire us t build new mdels f the universe. Mdels are nt the reality, hwever. There is n pint in arguing if the universe is a clck, a set f particles r an utput f cmputatin. All these mdels are tls t deal with the unknwn and t make discveries. And the mre tls we have, the mre effective and insightful we can becme.
It can be imagined that cmparable t the prcess f building previus scientific mdels, develping the “cmputer simulatin” metaphr-based mdel will als be a hugely rewarding exercise.
28．What des the authr intend t d by challenging a hypthesis?
A．Make an assumptin.B．Illustrate an argument.
C．Give a suggestin.D．Justify a cmparisn.
29．What des the phrase “cntingent n” underlined in Paragraph 2 prbably mean?
A．Accepted by.B．Determined by.C．Awakened by.D．Discvered by.
30．As fr Kant’s argument, the authr is _________.
A．appreciativeB．dubtfulC．uncncernedD．disapprving
31．It is implied in this passage that we shuld _________.
A．cmpare the current mdels with the previus nes
B．cntinue explring the classical mdels in histry
C．stp arguing whether the universe is a simulatin
D．turn simulatins f the universe int realities up.
1.句子：Searching the term “simulatin hypthesis” (模拟假说) returns numerus results that debate whether the universe is a cmputer simulatin — a cncept that sme scientists actually take seriusly.
分析：
主干为 “Searching the numerus results”，动名词短语 “Searching the term” 作主语，“returns” 为谓语。
“that debate whether the universe is a cmputer simulatin” 是定语从句，修饰 “results”，其中 “whether the universe is a cmputer simulatin” 是宾语从句，作 “debate” 的宾语。
破折号后的 “a cncept that sme scientists actually take seriusly” 是同位语，解释 “simulatin hypthesis”，其中 “that” 引导定语从句修饰 “cncept”。
译文：搜索 “模拟假说” 这一术语会得到许多结果，这些结果围绕 “宇宙是否是计算机模拟” 展开争论 —— 这是一个连一些科学家都认真对待的概念。
2.句子：If empirical experience fails t reveal reality, reasning wn’t reveal reality either since it relies n cncepts and wrds that are cntingent n ur scial, cultural and psychlgical histries.
分析：
本句为多重复句，“If empirical experience fails t reveal reality” 是条件状语从句。
主句为 “reasning wn’t reveal reality either”，“since it relies n cncepts and wrds...” 是原因状语从句。
“that are cntingent n ur ” 是定语从句，修饰 “cncepts and wrds”。
译文：如果实证经验无法揭示现实，推理也无法揭示现实，因为它依赖于取决于我们社会、文化和心理历史的概念与词语。
背景知识：
1.模拟假说（Simulatin Hypthesis）：
该理论认为宇宙可能是高级文明通过计算机模拟生成的虚拟世界，由哲学家尼克・博斯特罗姆（Nick Bstrm）在 21 世纪初系统提出。尽管缺乏实证支持，但它引发了科学、哲学和科技领域的广泛讨论，与 “缸中之脑”“黑客帝国” 等概念有理论关联。
2.康德的认识论（Kant's Epistemlgy）：
康德提出 “物自体”（things-in-themselves）概念，认为人类只能通过感官和认知能力理解 “现象世界”，而无法触及客观现实的本质。这一观点为文章中 “宇宙不可知” 的论述提供了哲学基础。
3.科学模型的隐喻本质：
科学史上，模型常基于人类熟悉的隐喻构建：牛顿时代将宇宙比作 “时钟”（机械论），爱因斯坦时代用 “粒子模型” 解释物理现象，信息时代则衍生出 “宇宙模拟” 的新隐喻。这些模型是理解工具，而非现实本身。
阅读微技能（解题技巧）：
1.推理判断题的逻辑链分析：
如第 28 题问作者挑战假说的目的，需结合第一段结尾 “We can, instead, use this idea t advance scientific knwledge”，明确作者通过质疑假说转向 “利用假说来推进科学” 的建议，而非单纯论证或假设，故答案选 C。
2.词义猜测的上下文关联：
第 29 题 “cntingent n” 所在句中，“since it relies n” 表明因果关系，“relies n”（依赖）与 “determined by”（由…… 决定）语义相近，可通过逻辑替换锁定 B 选项。
3.作者态度题的隐含线索抓取：
第 30 题关于作者对康德的态度，文中未直接表态，但通过 “Kant argued he said...” 的客观引用，以及后续 “if we accept that the universe is unknwable” 的顺承论述，可推断作者对康德观点持认可（appreciative）态度，而非怀疑或反对。
4.隐含主旨题的段落结构梳理：
第 31 题需整合第四段 “N pint in arguing” 和第五段 “develping the mdel will be rewarding” 的核心观点：作者强调停止争论 “宇宙是否为模拟”，转而将其作为模型工具探索，对应 C 选项。
总结:
本文通过哲学假说与科学模型的交叉分析，引导读者从 “是否为模拟” 的争论转向 “如何用模拟概念推动认知”。解题时需紧扣 “假说→模型→工具” 的逻辑主线，结合长难句的结构拆解和背景知识。

Passage 3
（24-25高二下·河南郑州·期末）A new study reveals a breakthrugh in the field f snakebite treatment. Researchers, led by David Baker frm the University f Washingtn, have designed new prteins — unlike any fund in nature — that can inactivate (使……灭活) sme f the mst pisnus cmpnents f snakebite txins.
Snakebites represent a substantial glbal health issue, affecting millins f peple each year. Accrding t the Wrld Health Organizatin, ver 2 millin peple suffer frm snakebites annually, with mre than 100, 000 deaths and 300, 000 cases f permanent disabilities. Current treatment ptins, mainly btained frm animal bld, ften present weaknesses, including high prductin csts, limited efficiency, and severe side effects, such as causing shck and breathing difficulties.
With these challenges, Baker and his team have made effective use f deep learning tls t develp artificial prteins capable f attaching t and inactivating txins. The study fcuses n a specific grup f snake prteins knwn as three-finger txins. These txins ften avid the immune system (免疫系统), making traditinal treatments ineffective. Ntably, the newly designed prteins prvide significant prtectin against deadly amunts f three-finger txins in mice, achieving survival rates ranging frm 80% t 100%.
By aviding the lengthy and resurce-intensive prcesses assciated with traditinal antibdy develpment, this apprach culd lead t mre accessible and affrdable treatments. Als, the new prteins are smaller, allwing fr greater penetratin (渗透) int bdy systems t quickly inactivate the txins and reduce damage. The efficiency and speed at which these prteins can be designed and prduced using AI indicate a transfrmative shift in drug discvery prcesses, especially in resurce-limited settings.
While the study’s findings are encuraging, the researchers acknwledge that traditinal antitxins will remain central t snakebite treatment fr the near future. The newly created cmputer-designed antitxins can be integrated int existing treatment as additins, enhancing the verall effectiveness f established treatments. Meanwhile, scientists believe the new methd emplyed in this study culd be beneficial t tackling ther diseases, ptentially leading t the emergence f less expensive medicines fr varius health challenges.

Passage 4
（云南省文山州、红河州联合考试2024-2025学年高二下学期7月期末英语试题）Chinese scientists at Westlake University in Zhejiang prvince have made an exciting discvery in slar pwer. They have created an extremely thin and flexible type f slar cell that can turn sunlight int electricity with a recrd efficiency f 23.4 percent. These cells, abut as thick as a human hair, use tw special materials t capture sunlight: pervskite (钙钛矿) and cpper indium gallium selenide (CIGS,铜铟镓硒).
Imagine a single pervskite slar cell as a single-layer cake. Nw, think f a tandem (串联的) slar cell as a cake with multiple layers, each with a different flavr. Each layer f this cake can “catch” specific parts f sunlight. This allws the tandem slar cell t absrb mre sunlight and turn it int electricity mre efficiently than the “single-layer” nes, making it better than traditinal slar cells.
In late 2023, researchers Tian Liuwen and Wang tried new ways t cat the material. After mnths f testing, they fund a way t create a unifrm pervskite layer. This breakthrugh imprved efficiency and made it ready fr real-wrld use.
These thin cells culd cmpletely change hw we use slar pwer. Because they’re flexible, yu can put them n all srts f curved surfaces, such as car rfs, building facades, r even clthing. They are als much lighter than traditinal slar panels, which makes them cheaper and easier t transprt and set up. This is a significant advantage, especially fr space missins.
With many cuntries arund the wrld trying t reduce carbn emissins, these efficient, lightweight slar cells culd play a vital rle in mving away frm fssil fuels. It seems that smething as thin as a hair culd help us slve sme f the wrld’s biggest challenges.

Passage 5
（24-25高二下·安徽芜湖·期末）Scientists in China have recently used a pwerful tl called CRISPR t make tmates taste sweeter. CRISPR is a gene-editing technlgy that allws researchers t change specific parts f a plant’s DNA．In this case, the scientists increased the amunt f natural sugars in tmates by abut 30%, making them taste better withut changing their size.
The researchers fcused n tw genes in the tmat plant that usually reduce sugar levels as the fruit ripens. By editing these genes, they were able t keep mre glucse and fructse the sugars that make tmates sweet—inside the fruit. The results f their study were published in the scientific jurnal Nature.
This develpment is part f a larger effrt t make vegetables mre attractive t cnsumers. Other scientists are wrking n creating seedless blackberries that are less bitter. The idea is that if vegetables taste better, mre peple will want t eat them, leading t healthier diets.
The success with tmates culd als help imprve ther fruits like apples and pears. By using similar gene-editing techniques, scientists hpe t raise the taste and quality f varius crps. Hwever, it will take several years befre these gene-edited tmates are available in supermarkets. They must g thrugh strict safety apprvals t ensure they are safe fr cnsumptin.
Gene editing is different frm traditinal genetic mdificatin, which typically adds genes frm ther species. Gene editing makes precise changes within the plant’s wn DNA．This methd is cnsidered mre natural and may face fewer apprval hurdles in sme cuntries. Despite the ptential benefits, there are still wrries abut gene-edited fds. Sme peple wrry abut the lng-term effects n health and the envirnment. Others are cncerned abut labeling and the right t knw what is in their fd.
In cnclusin, the use f CRISPR t create sweeter tmates represents a significant imprvement in agricultural science. By imprving the taste f vegetables, scientists hpe t encurage healthier eating habits. Hwever, it is imprtant t ease public cncerns and ensure that these new fds are safe and prperly regulated befre they becme widely available.
1．Why d scientists use CRISPR n tmates?
A．T reduce glucse and fructse inside the fruit.
B．T make tmates resistant t sugar levels as the fruit ripens.
C．T develp new varieties f tmates t attract cnsumers.
D．T increase the fruit’s sweetness withut changing its vlume.
2．Why des the article mentin ther prjects like seedless blackberries?
A．T shw that CRISPR can als be used t create mre vegetables.
B．T prve that imprving the attractin f vegetables is a brader scientific gal.
C．T argue that less bitterness is the mst attractive gal in gene-edited crps.
D．T cmpare CRISPR’s effects with thse f traditinal farming.
3．What des the underlined wrd “hurdles” in paragraph 5 mst likely mean?
A．Challenges that culd delay legal apprval.
B．Tests that must be scientifically repeated.
C．Plicies that guide internatinal cperatin.

A．Their imprved taste will change peple’s unhealthy eating habits.
B．They are expected t slve public wrries.
C．They may imprve nutritin if accepted by the public.
D．They may becme widely available arund the wrld.
Passage 6
（24-25高二下·安徽芜湖·期末）If the idea f rbts challenging humans in a rad race makes yu picture a nightmare where machines are taking ver sprts, then fear nt, fr nw at least.
Mre than 20 tw-legged rbts cmpeted in the wrld’s first humanid (人形机器人) half-marathn in China n Saturday, and — thugh technlgically impressive — they were far frm beating their human masters ver the lng distance. Teams frm several cmpanies and universities tk part in the race, a shwcase f China’s advances n humanid technlgy. And the chief f the winning team said their rbt — thugh beaten by the humans in this particular race — was equal t similar mdels frm the West.
Over the past few mnths, vides f China’s humanid rbts perfrming bike rides, rundhuse kicks and side flips have becme ppular n the Internet, with state media ften prmting them as a key ptential driver f ecnmic grwth. In a 2023 plicy dcument, China’s Ministry f Industry and Infrmatin Technlgy identified the humanid rbtics industry as a “new frntier in technlgical cmpetitin,” setting a 2025 target fr mass prductin and secure supply chains fr essential parts.
Fears have grwn in recent years abut hw AI — and rbts — may ne day beat humans. And despite AI’s rapid rise in fields like security and emplyment, humans still lead in running — as prven by Saturday’s race. The rbts cmpeted against 12,000 human runners, running side by side with them in a fenced-ff lane. Just as human runners needed t refill themselves with water, rbt cmpetitrs were allwed t get new batteries during the race. Cmpanies were als allwed t replace their rbts with replacement when they culd n lnger cmpete, thugh each replacement came with a 10-minute delay.

Passage 7
（24-25高二下·河北邢台·阶段练习）Crnell University researchers have develped a new rbtic framewrk pwered by artificial intelligence — called RHyME (Retrieval fr Hybrid Imitatin under Mismatched Executin) — that allws rbts t learn tasks by watching a single hw-t vide.
Histrically, rbts were finicky learners. They required precise, step-by-step directins t cmplete basic tasks and tended t call it quits when things went ff script (偏离计划). RHyME, hwever, culd fast-track the develpment f rbtic systems by reducing the time, energy and mney needed t train them.
“One f the annying things abut wrking with rbts is cllecting s much data n the rbt ding different tasks,” said Kushal Kedia, a dctral student in cmputer science. “That’s nt hw humans d tasks. We lk at ther peple as inspiratin.”
T help rbts learn mre naturally, researchers are using human demnstratin vides in a lab setting, hping rbts will pick up task sequences (顺序) mre quickly thrugh this methd, which is part f a machine learning apprach called imitatin learning.
Despite these advances, hme rbt assistants are still far frm reality because rbts lack the ability t handle many unexpected situatins in the physical wrld. One challenge is that humans mve t fluidly (流畅地) fr rbts t cpy. Training rbts with vides requires careful, slw demnstratins because any mismatch between the vides and the rbts’ actins can cause failure.
RHyME is designed t slve this prblem. It helps rbts becme mre adaptive by allwing them t use their memry and make cnnectins when perfrming tasks they have seen nly nce. Fr example, a rbt that watches a persn place a mug in a sink can recall similar actins frm ther vides and apply that knwledge.
This new apprach reduces the need fr large amunts f training data. RHyME requires nly 30 minutes f rbt data. In lab tests, rbts trained with RHyME shwed ver a 50% increase in success rates cmpared t earlier methds, ffering a prmising path tward smarter, mre flexible rbts.
1．What des the underlined wrd “finicky” in paragraph 2 mean?
A．Easy-t-train.B．Adaptive.C．Quick-t-learn.D．Picky.
2．Why is vide training challenging fr rbts?
A．Human mvements are t smth t cpy.
B．Rbts are unable t deal with tasks in rder.
C．Real-wrld envirnments change frequently.
D．Demnstratin vides ften cntain errrs.
3．What advantage des RHyME have ver traditinal training methds?
A．It allws rbts t crrect human mistakes.
B．It requires minimal demnstratins.
C．It helps rbts avid unexpected situatins.
D．It remves behaviral mismatches.
4．What wuld be a suitable title fr the text?
A．Vide Learning: a Way t Get Rid f Errrs

（2025高二·全国·专题练习）Chinese Scientists Develp Gene Therapy
Which Culd Delay AgingBy Anna Matte
4 February 2021
Scientists in Beijing, China have develped a new gene therapy that can turn back sme f the effects f aging in mice. The therapy als 1 their lives. This may ne day help 2 as well.
The gene therapy invlved 3 a gene called kat7. Scientists have fund this gene t be the main 4 f aging in cells.
Qu Jing f the Institute f Zlgy at the Chinese Academy f Sciences is ne f the supervisrs f the prject. After six t eight mnths, Qu said that the mice shwed an verall 5 in their appearance and grip strength. Mre imprtantly, she added, “They have an extended lifespan f abut 25 percent.”
The kat7 gene, Qu said, was mst 6 in the aging f cells. It is ne f tens f thusands f genes fund in the cells f mammals.
Researchers disabled the kat 7 gene in the livers f the mice in the study. They used a(n) 7 called “lentiviral vectr” t mdify the gene by inserting a genetic material int the cell.
Qu said they tested the 8 f kat7 gene in different kinds f cell types, including human stem cells, human liver cells and muse liver cells. Fr all thse cells, the researchers culd nt find any cellular txicity. And fr the mice, she 9 , “We als didn’t see any side-effects yet.”
Even with these 10 , Qu tld Reuters, the methd t disable the kat 7 gene is still a lng way frm being 11 fr human tests. She said they need mre tests in ther human cells and muse rgans befre 12 the methd n human aging and ther health 13 .
Qu said she hpes t be able t 14 the methd n primates next and find a way t delay aging even by a very 15 percentage... in the future.
