While they look like they could have been made yesterday,the footprints were pressed into mud 21,000 to 23,000 years ago,according to radiocarbon dating of the seeds of a water plant that were preserved above and below the fossils.This date dramatically pushed back the timeline of humans'history in the Americas, the last land to be settled by prehistoric people.The 61 dated prints,which were discovered in the Tularosa Basin,near the edge of an ancient lake in White Sands National Park,were made at a time when many scientists think that massive ice sheets had stopped human passage into North America,indicating that humans arrived in the region even earlier. However,some archaeologists questioned the age of the footprints established by those initial findings. They noted that water plants such as Ruppia cirrhosa- the one used in the 2021 study-can acquire carbon atoms from the water rather than the air,which can result in a misleadingly early date. In a follow-up study published Thursday in the journal Science,researchers said they have produced two new lines of evidence to support their initial dates. "Even as the original work was being published,we were speeding up to test our results with multiple lines of evidence,said Kathleen Springer,co-lead author of the new Science paper,in a news release."We were confident in our original ages,as well as the strong evidence.” When and how early humans first moved to the Americas has long been debated and remains poorly understood.Current estimates range from 13,000 years (横线下方不可作答) 班级： 姓名： to the unknown :35分) ago to more than 20,000 years ago.However,the earliest archaeological evidence for the region's settlement is insufficient and often controversial. making the footprints especially important. 1.What is paragraph 2 mainly about? A.The purpose of the new research. B.The method of the dating. C.The significance of the footprints. D.The efforts of the scientists. 2.Why did some archaeologists question the age of the footprints? A.It goes against the prior knowledge. B.The prints seem to be made recently C.The previous research method is improper. D.The then massive ice sheets are misleading. 3.What will the author probably talk about next? A.The doubt about the age of the footprints. B.The new evidence of the fossilized footprints. C.An agreement between the two sides of the debate. D.Early humans'hardship of moving to the Americas. 4.What is the purpose of the text? () A.To explain the process of archaeological study. B.To report the discovery of fossilized footprints. C.To introduce a debate on the age of the foot- prints. D.To present the progress of the footprint research. (2024·东北三省四市联考) Humans have sailed the oceans'surfaces for millennia,but their depths remain effectively uncharted.Only about a quarter of the seafloor has been mapped at high resolution.Maps of most regions display only approximate depths and often miss entire underwater mountains or canyons(峡谷). So researchers have introduced some deep-diving experts:Elephant Seals.Scientists have been placing trackers on them around Antarctica for years,gathering data on ocean temperature.For a new study,the 29] 选择性必修第四册 researchers compared these divers'location and depth data with some of the less detailed seafloor maps.They spotted places where the seals dove deeper than should have been possible according to the maps-meaning the existing depth estimates were inaccurate. In eastern Antarctica's Vincennes Bay,the diving seals helped the scientists find a large,hidden underwater canyon of more than a mile in depth.An Australian research ship called RSV Nuyina later measured the canyon's exact depth using sonar(声纳)， and the researchers have proposed naming their find the Mirounga-Nuyina Canyon-honoring both the ship and the involved Elephant Seals,genus Mirounga. But seals can't chart the entire ocean floor.The trackers used in the study could pinpoint a seal's geographical location only within about 1.5 miles, which allows for useful but not exactly high-resolution data.Plus,because the seals don't always dive to the bottom of the ocean,they can reveal only where the bottom is deeper than in existing maps-not shallower. Deep-sea research experts suggest improving on these data by using more precise tracking devices and analyzing the seals'diving patterns to determine whether they have reached the seafloor or simply stopped going down. The potential use of the current seal-dive data is to gather information about the deep ocean around Antarctica,specifically regarding the location and depth of seafloor canyons.This data can be valuable for predicting how Antarctica's ice will melt.By understanding the presence and characteristics of these canyons,scientists can better assess how warmer water from the deep ocean flows towards the ice along the continent's coast.This knowledge is crucial for accurately modeling and predicting the future behavior of Antarctica's ice sheets and their contribution to the sea-level rise. 5.How did the researchers find out the depth inaccuracies? A.By gathering temperature data. B.With the help of seals'diving. C.By improving resolution of maps. D.With the trackers placed on canyons. 红对勾·讲与练5 6.Why is the discovery of the Mirounga-Nuyina Canyon mentioned? A.To provide more reference data. B.To introduce a new topic. C.To give supporting evidence. D.To make a comparison. 7.What can we infer from the last paragraph?( A.Researchers can assess ocean features. B.Data can be used to track ice location. C.Underwater flow can be controlled. D.Scientists can monitor ice melting. 8.What is the text mainly about? ) A.Seals assist scientists in charting ocean floor. B.Seals advance tracking devices'precision. C.Scientists draw inspiration from seals. D.Scientists uncover seals'diving patterns.
