英文阅读与练习24 The mystery of the Pacific “cold tongue” 太平洋“冷舌”之谜 1A narrow region of the eastern Pacific Ocean has been getting colder for the past 30 years, challenging global trends and confusing many scientists.Over at least three decades, the region has cooled by roughly half a degree, which has been causing scientists to wonder how long that will hold. 2The unusual phenomenon, known as the “cold tongue”, is affecting a vast area of ocean west of South America. Scientists are not entirely certain what is keeping the “cold tongue” cool. Richard Seager, from the Earth Observatory at Columbia University, said one factor appears to be trade winds in the equatorial region, which carry warm water away from the surface, stimulating cooler water to rise. “The trade winds blow from east to west across the tropical Pacific Ocean,” Seager said. “As the water is driven away from the surface,water flows up from below. And since the water below the surface is cold, this creates the‘cold tongue’.” 3Yet despite the effect of these winds, the “cold tongue” has puzzled scientists,because advanced climate computer models suggest that the waters should have been warming for decades at a faster rate than the rest of the Pacific due to rising greenhouse gas emissions. 4Pedro DiNezio of the University of Colorado Boulder, considers it “the most important unanswered question in climate science”.Scientists can't predict when it will end or start warming since the cause is unknown.According toNew Scientist, this has huge worldwide implications, including determining California's permanent drought and Australia's wildfires. More profoundly still, it could even alter the extent of climate change globally by understanding how sensitive Earth's atmosphere is to rising greenhouse gas production. 5Despite this, the overall ocean temperatures are rising. Solving the puzzle of the“cold tongue” isn't about proving climate models wrong. Rather, the “cold tongue” is the last big piece of the puzzle. Fit that in and we can build a more accurate picture of how life will change in a warming world and how best to prepare for that future. Reading Check 1. What may be the cause of the“ cold tongue”? A. The arrival of ocean currents. B. Trade winds in the equatorial regions. C. The change in the direction of water flow. D. The temperature differences between sea and land. 2. Why are scientists confused about the“ cold tongue” phenomenon? A. It has lasted for many years. B. It forms a minor ocean ecosystem. C. It contradicts the global warming trend. D. It mirrors increasing carbon emissions. 3. What makes solving the“ cold tongue” puzzle important? A. It can help predict droughts in California. B. It contributes to adjusting ocean temperatures. C. It can help improve the accuracy of climate models. D. It offers insights into dealing with future climate events. 4. What is the purpose of the text? A. To stress the effect of climate change. B. To introduce an unusual phenomenon. C. To explain reasons for strange natural disasters. D. To appeal to people to pay more attention to the ocean. Language Study Ⅰ.

This hidden wonder is none other than a giant floating island.The island, composed of plants and trees,occasionally floats around the lake, causing a significant inconvenience by blocking a vital bridge. Later, the local people proposed a solution to this problem. Every year, local boat owners work together and push the island away from the bridge. 2Lake Chippewa was born in 1923 when a vast bog was transformed through flooding.Soon after that, many of the peat bogs started rising to the surface and became perfect growing spots for plants, with seeds carried by wind and wild birds to this floating place.Over the years, these bogs have grown plants and trees and turned into full islands.As time goes by, plants take root, and the oldest islands even have trees that act as sails when the wind blows, moving the entire floating mass around the lake. 3Although the decades-old floating island does not relocate (迁移) constantly, when it does, it causes trouble for the community by blocking the vital bridge that serves as the sole passage between the lake's east and west sides. The only solution is to gather a fleet of boats, and not just one or two, but dozens of boats working together to push the island away.“It takes a community's effort, and you must have the winds at your back to push them in,”said a resident. Moving the island also requires precision (精确), as merely relocating it a short distance may result in its return within days. 4Some people have suggested blowing up the floating island to get rid of the problem.However, the big bog in Lake Chippewa has been around for decades, and in that time a wealth of animal and plant species have made it their home. Therefore, local authorities prefer it be dealt with in a way that won't negatively impact wildlife, highlighting the delicate balance between human convenience and environmental conservation. The annual tradition of relocating Lake Chippewa's floating island is evidence of the coexistence of humanity and nature, a heartwarming display of community unity, and a reminder of the importance of preserving the unique habitats that enrich our world. Reading Check 1. What does the underlined word“ solution” in paragraph 1 refer to? A. Building a new bridge. B. Transforming the vast bog. C. Moving the floating island away. D. Reconstructing the local community. 2. What is paragraph 2 mainly about? A. The formation of the floating island. B. The history of flooding in Lake Chippewa. C. The abundance of species in Lake Chippewa. D. The impact of the wind on the floating island. 3. What do we know about the relocation work from paragraph 3? A. It is usually finished within days. B. It is demanding in cooperation and precision. C. It can only be carried out during windless days. D. It greatly disturbs the community residents' lives. 4. Why have the local authorities refused to blow up the island? A. To save costs for local people. B. To ensure the safety of residents. C. To increase the bond between communities. D. To protect the wildlife species on the island. Language Study Ⅰ.

A team of Chinese scientists aimed to deal with this environmental concern by developing an eco-conscious alternative. 2In a study published in the journal Science Advances, a team at the Chinese Academy of Sciences' Institute of Process Engineering describes how they engineered biodegradable (可生物降解的) glass made from amino acids (氨基酸). That glass would have a smaller impact on the environment and can be broken down in a few weeks or in several months. 3In a test, glass beads (玻璃珠) made from amino acids were placed under the skin of mice, and the breakdown of the beads and the skin healing process were observed for 30 days. A diagram of the study shows how the mice's bodies broke down the beads. In that month, the glass implant degraded beneath the skin, the wound site healed, and fur grew back. “Throughout the experimental period, no mice exhibited any pain-related behavior that may have been caused by the glass implantation, and none of them experienced obvious weight loss,” the researchers wrote in their paper. 4Although amino acids do degrade over time in the environment, this biodegradable glass is not as durable as traditional glass, because amino acids can be broken down quickly in heat. In order to overcome this hurdle, the researchers chemically modified the amino acids using the heating-cooling procedure applied to glass manufacturing. This is when materials for the glass are heated to become soft and then rapidly cooled so as to make the glass tougher. 5“It's important to point out that this biodegradable glass is currently in the lab stage,and far from large-scale commercialization,” emphasized Yan Xuehai, a professor involved in the study, in a press release. Reading Check 1. What is an advantage of the new glass? A. It can be recycled at a low cost. B. It is produced without pollution. C. It takes less time to be broken down. D. It has a wide range of applications. 2. Why did researchers implant glass beads into mice? A. To assess whether the glass is biologically harmless. B. To investigate why amino acids are medically useful. C. To explore how long it takes for the glass to degrade. D. To observe if the glass can be melted down in mice's stomachs. 3. What does the underlined word“ hurdle” in paragraph 4 refer to? A. The instability of amino acids. B. The difficulty of selecting materials for the glass. C. Environmental problems caused by traditional glass. D. The challenge of improving the heating-cooling procedure. Language Study Ⅰ. Difficult sentence in the text Although amino acids do degrade over time in the environment, this biodegradable glass is not as durable as traditional glass, because amino acids can be broken down quickly in heat. 虽然氨基酸会随着时间的推移在环境中降解，但这种可生物降解的玻璃并不像传统玻璃那样耐用，因为氨基酸会在高温下迅速分解。 【点石成金】本句中，Although 引导让步状语从句，主句是this biodegradable glass is not as durable as traditional glass，because引导原因状语从句。 Ⅱ.
