语篇解读：
本文是一篇议论文。近年来街道安全改善，但行人(尤其是儿童)的活动能力下降，家长因交通隐患大多开车送孩子上学。荷兰作者Thalia Verkade和Marco te Br mmelstroet对此类现象不满，在他们的新书中呼吁重新思考街道在我们生活中的作用。作者认同新书观点，呼吁重新审视街道规划。
深度解析：
28．C [细节理解题。根据第一段内容可知，交通研究也显示行人(尤其是儿童)的活动能力在下降。许多家长表示道路上车流量太大，孩子步行上学不安全，因此他们选择开车送孩子上学。C项“人们步行更少，开车更多”符合题意。故选C。]
29．A [细节理解题。根据第三段中“Describing her alarm at its proposed replacement with an expressway，Jane Jacobs called on her mayor to champion‘New York as a decent place to live，and not just rush through．’”可知，Jane Jacobs描述了当得知公园计划被高速公路取代时的恐慌，她呼吁市长将纽约建设成一个宜居的好地方，而不仅仅是一个人们匆匆而过的地方。A项“保持他们城市的宜居性”符合题意。故选A。]
30．B [推理判断题。根据第四段中“Although these campaigns were widespread，the reality is that the majority of the western cities were completely redesigned around the needs of the motor car．”可知，尽管这些运动很普遍，但现实是大多数西方城市都围绕着机动车的需求进行了彻底的重新设计。再结合最后一段中“We invest a lot...but we fail to account for the true costs．”可知，这些运动并没有解决真正的需求，说明在很大程度上它们是无效的运动。B项“它们在很大程度上被证明无效”符合题意。故选B。]
31．A [标题归纳题。文章的核心批判是当前的城市规划和交通方式(以车为主)让人们“匆匆而过(rush through)”，只追求通行效率(help us rush through)，却忽视了这种“匆忙(rush)”带来的社会成本(如儿童失去安全活动的空间，活动能力下降)。作者呼吁重新思考街道的作用，让城市成为生活的地方，而不仅仅是通道。A项“Why the Rush？(我们为何要如此匆忙？)”直接点明了文章质疑的核心——这种追求速度、忽视生活质量的“匆忙”是否有必要？它是否值得付出如此高的社会代价？这个标题最能引发人们的批判性思考。故选A。]

(2025·河北秦皇岛模拟)Construction workers recently found the ruins of a large pyramid beside a highway in Mexico．After discovering the site，researchers collected many ancient objects that will be studied in their laboratories over the coming months．The structure was found in June 2024 during highway expansion work in Hidalgo，central Mexico．The discovery happened by chance as workers were adding a third lane to the federal highway，showing how ancient structures can still be found during modern construction projects．
Scientists from Mexico's National Institute of Anthropology and History went to study the site．They used drones to take pictures and collected 155 items，including pieces of pottery，stone tools，and shells．To protect the old building，they built a large wall around the pyramid，which is 43 meters long and 11.7 meters high．
The pyramid is part of an old settlement called San Miguel，built between 650-1519 CE．The area was ruled by the “Metzca lordship”，which influenced the region until the 1500s．People have lived in this region for a very long time，with the oldest settlements dating back at least 14，000 years．This shows that many different groups of people have lived here over thousands of years．
Scientists keep finding hidden ancient buildings in Mexico and other parts of the Americas．Many discoveries are made using LiDAR，a technology that uses laser light to see things concealed under plants and trees．This tool helps archaeologists (考古学家) find old structures that they couldn't see just by looking at the ground．
Last year，researchers used LiDAR to find an 18-kilometer road that connected ancient Maya cities over 1，200 years ago．In Guatemala，they also discovered a previously unknown Maya civilization with 964 settlements connected by 177 kilometers of ancient roads．These findings show that the Americas had complex and thriving societies long before European settlers arrived．The discoveries remind us how advanced these ancient civilizations were，though their development was later interrupted by colonization．Each new discovery helps build a more complete picture of these remarkable ancient societies．
1．What action did scientists take first after discovering the site
A．They restored the pyramid．
B．They contacted local authorities．
C．They removed all artifacts．
D．They photographed the site．
2．What does the underlined word “concealed” in paragraph 4 probably mean
A．Ancient． B．Hidden．
C．Risky． D．Connected．
3．What does the author convey in the last paragraph
A．Maya civilization was primitive．
B．European settlers improved local life．
C．Ancient Americas had advanced societies．
D．Modern technology surpasses ancient wisdom．
4．What's the best title for the text
A．Mexico Builds New Highways
B．Ancient Ruins Need Protection
C．Unexpected Discovery Reveals Past Civilization
D．Modern Technology Helps Archaeological Work

(2025·重庆三模)A new study，published in the Proceedings of the National Academy of Sciences，concludes that proper reductions in beef production，particularly in wealthier nations，could significantly slow down climate change by allowing forests to regrow on former grasslands．
The study used remote sensing technology to map grassland productivity and estimate benefits of reducing beef production，finding that restoring all potentially forested grasslands globally could store 445 gigatons (千兆吨) of CO2 by 2100—equal to amount of fossil fuel emissions (排放) over a decade．
“We can achieve enormous climate benefits with proper changes to the total global beef production，” says Matthew N．Hayek，an assistant professor in New York University's environmental studies department．“By focusing on regions with potentially high carbon sequestration (隔离) in forests，some restoration strategies could maximize climate benefits while minimizing changes to food supplies．”
The team sees high and upper-middle-income countries as possible candidates for forest restoration，where grass grows only during a short growing season．These regions，such as parts of North America and Europe，have some current grasslands that do not produce very much grass per acre，and thus have potential to grow thick forests able to absorb a lot of carbon．In contrast，lower-income regions like sub-Saharan Africa and South America，where much more grass can grow year-round，can contribute to balancing reduced production elsewhere．
Matthew acknowledged that reforestation cannot replace cutting down on fossil fuel pollution，but works together with it to help fight climate change．“In many places，this regrowth could occur naturally without any human involvement．However，in some places，with especially damaged environments or soils，native and diverse tree-planting could give regrowth a helping hand，” says Matthew．
Although the findings do not call for extreme changes to global food production，the team emphasizes that immediate action is essential to meet climate goals．Targeted policies are called for to prioritize forest recovery in high-impact areas—for instance，by offering beef producers rewards for forest land conservation or purchasing their company shares．
5．Why is “445 gigatons of CO2” mentioned in paragraph 2
A．To clarify a specific climate goal by 2100．
B．To quantify the benefits of grassland recovery．
C．To show the difficulty of cutting fossil fuel use．
D．To highlight the role of remote sensing technology．
6．What can be learned about the grasslands in sub-Saharan Africa and South America
A．They are ideal for reforestation．
B．They have a short growing season．
C．They are expected to feed more animals．
D．They have a low capacity for carbon absorption．
7．What policy is suggested for forest recovery
A．Limiting beef exports．
B．Increasing agricultural taxes．
C．Providing financial benefits．
D．Introducing advanced technology．
8．What might be a suitable title for the text
A．Targeted Beef Cuts Bring Climate Benefits
