But does it have a future? By 2050, London's weather could resemble that of Barcelona, with long stretches of summer drought. These ancient trees were not designed to thrive in such conditions. Around the world, millions of creatures facing unprecedented temperatures and habitat loss are on the move. We do not tend to think of trees as migratory: they are slow­growing and rooted to the ground. Faced with this problem, the ecologist Charlie Gardner is one of a growing number proposing a radical, controversial solution: we help the trees on their march. Some scientists advocate moving individual species hundreds of kilometres north, within the country and from abroad. Others say entire ecosystems should be translocated, moving multiple species at once. The “assisted migration” is divisive. Conservationists have long argued against introducing non­native species. They have concerns about unintended consequences of assisted migration. “Large­scale moving of ecosystems can't be undone(撤销), so should be very much a last choice，” said Andrew Allen from the Woodland Trust. Allen believes we should prioritise helping native trees adapt to changes by encouraging natural regeneration, expanding and connecting existing woodlands. But others say those arguments fail to deal with speed or size of change caused by the climate crisis. “Earlier in my career the narrative was all about restoring past baselines, and then, as I got more independent in my research, I realised that's impossible. We are changing the climate so much, so we have to be a little more inventive. When we have examples of assisted migration, it's often with species which are absolutely on the edge of extinction and have run out of other options，” said Sarah Dalrymple, a conservation ecologist from Liverpool University, who is part of the task force. She wants to see assisted migration explored earlier, working with species before their populations become so small. “You can never get rid of all the risks, but there is also risk in inaction，” she said. “The risk of inaction is increasing every day.” (　　) 1. What is the problem facing ancient trees in London? A. Long summer. B. Habitat destruction. C. Extreme weather. D. Slow growth. (　　) 2. Which of the following statements may Andrew Allen agree with? A. Large­scale moving of ecosystems is impossible. B. Assisted migration may contribute to bad results. C. Non­native species are beneficial to ecosystems. D. Native species can survive changes by themselves. (　　) 3. What does Sarah Dalrymple urge people to do in the last paragraph? A. Stop changing the climate. B. Have more options to help species. C. Help native trees to adapt to climate changes. D. Take action earlier to prevent species' extinction. (　　) 4. What might be the author's attitude towards assisted migration? A. Supportive. B. Cautious. C. Objective. D. Doubtful. B[2026南通如皋调研] The Ediacaran Period, spanning from about 635 to 541 million years ago, was a crucial time in Earth's history. It marked a transformative era during which complex, multicellular organisms(多细胞生物) emerged, setting the stage for an explosion of life. But how did this explosion of life unfold? Researchers from the University of Rochester in New York, US, have uncovered strong evidence that Earth's magnetic field(磁场) was in a highly unusual state when the large animals of the Ediacaran Period diversified and thrived. According to John Tarduno, a professor of geophysics in the university's Department of Earth and Environmental Sciences, one of the most remarkable life forms during the Ediacaran Period was the Ediacaran fauna—a handful of strange creatures found in Australia, Canada and the English Midlands. They were notable for looking like early animals and some even reached more than a meter in size and were able to move, indicating that they probably needed more oxygen compared to earlier life forms. Tarduno and his team used innovative strategies and techniques to examine the strength of the magnetic field by studying magnetism locked in ancient feldspar and pyroxene crystals(辉石晶体) from a rock called anorthosite. These crystals contain magnetic particles(粒子) that preserve magnetization from the time the minerals were formed. By dating the rocks, researchers can construct a timeline of the development of Earth's magnetic field. Their data indicate that Earth's magnetic field during the Ediacaran Period was the weakest known to date, lasting for at least 26 million years. A weak magnetic field makes it easier for charged particles from the sun to strip_away lightweight atoms such as hydrogen from the atmosphere. If hydrogen loss is significant, more oxygen may remain in the atmosphere instead of reacting with hydrogen to form water vapor. These reactions can lead to a buildup of oxygen over time. The research suggests that during the Ediacaran Period, the extremely weak magnetic field caused a loss of hydrogen over at least tens of millions of years. This loss may have led to increased oxygen in the atmosphere and ocean, enabling more advanced life forms to emerge. (　　) 5. What did the researchers aim to find out? A. The origin of multicellular organisms. B. The link between oxygen and ecosystems. C. The impact of Earth's magnetic field on life. D. The effects of climate change on biodiversity. (　　) 6. How did the researchers conduct the study? A. By analyzing evolution of Ediacaran fauna. B. By examining magnetism in ancient minerals. C. By modeling the atmospheric changes in the lab. D. By comparing different periods in Earth's history. (　　) 7. What does the underlined phrase “strip away” in Paragraph 4 most probably mean? A. Remove. B. Cover. C. Gather. D. Generate. (　　) 8. What is the last paragraph mainly about? A. The significance of the research. B. A suggestion for further research. C. An analysis of the research method. D. An explanation for the research results.
