Scientists are urging that deep sea metal mining should be stopped temporarily. They warn in a report that it can cause severe and damaging effects on Pacific Ocean areas.

The recently-released report examined more than 250 published studies on deep Sea mining. The research was examined by the Deep Sea Mining Campaign——a collection of not-for profit organizations. The report centers on mining activities related to small metallic particles(颗粒; 微粒), called nodules, found on the seabed. The material can contain different metals. Increasing demand for these metals has led to a rise in deep-sea mining operations. The metals are commonly used in battery manufacturing(制造) and other technology products.

However, the scientists warn that mining for these nodules will cause irreversible(无法复原的)damage to an ocean already under pressure. The operations will affect areas across the South Pacific, including the nations of Kiribati, the Cook Islands, Nauru, Tonga and Papua New Guinea.

The report notes that a moratorium is the only responsible way to move forward until certain conditions surrounding deep-sea mining can be met. The scientists are calling for additional study to fully understand the environmental, social and economic risks.

Andrew Chin is the report’s lead researcher. He says in a statement that nodule mining will likely result in the loss of sea life and cause damage to deep seabeds for thousands of years. He adds that the operations can put people at risk who depend on the ocean and its continued health.

A company planning to be one of the first to carry out mining operations in the area is Canada’s Deep Green, which aims to begin by 2024. It seeks to mine metallic nodules to be used in power systems for electric vehicles. Deep Green Chief Executive Officer Gerard Barron defended the company’s plans in reaction to the report. He said deep-sea mining offered the best replacement for surface mining, which has a long history of pollution and destroying forests and wildlife.

1. Why are deep-sea mining operations on the rise?
A.More metals are needed.B.Surface mining is banned,
C.Battery industry is falling.D.The seabed is easy to find,
2. Which of the following best explains the word “moratorium” underlined in paragraph 4?
A.Loose measure.B.Thorough study.
C.Temporary stop.D.Permanent deal.
3. What can we learn from Andrew Chin’s words?

【推荐1】Australian scientists have successfully tested a new method for freezing and storing coral larvae(珊瑚幼虫), which they say could eventually help restore the wild coral reefs(珊瑚礁) threatened by climate change. They are struggling to protect coral reefs as rising ocean tem peratures damage ecosystems.The Great Barrier Reef has suffered four events of becoming white in the last seven years including the first one during a La Nina phenomenon, which typi-cally brings cooler temperatures.

Frozen coral can be stored and later reintroduced to the wild, but the current process requires some modern equipment including lasers(激光). The scientists say a new lightweight   “cryomesh(冷冻网)” can be produced cheaply and better protect coral. In a December lab tri- al,the world’s first with Great Barrier Reef coral, they used the “cryomesh” to freeze coral larvae at the Australian Institute of Marine Sciences(AIMS). “If we can protect the coral, we’ll have tools for the future to really help restore the reefs, and this technology for coral reefs in the future is a real game-changer,” said Mary Hagedorn, Senior Research Scientist at AIMS.

The “cryomesh” was previously tested on smaller and larger kinds of Hawaiian corals. Some trials on the larger kinds failed. But then other trials are continuing with larger varieties of Great Barrier Reef coral. The trials involved scientists from AIMS, the Smithsonian National Zoo and Conservation Biology Institute,the Great Barrier Reef foundation and the Taronga Conservation Society Australia as part of the Reef Restoration and Adaptation Program.

The technology,which will help store coral larvae at - 196 ℃, was invented by a team from the University of Minnesota’s College of Science and Engineering. It was first tested on corals by PhD student Nikolas Zuchowicz. “This new technology that we’ve got will allow us to do that, and it can actually help to support the growing and restoration of wildlife in water,” said Jonathan Daly of the Taronga Conservation Society Australia.

1. What is the new method of restoring the coral reefs?
A.Keeping coral larvae warmer.
B.Keeping coral larvae by freezing them.
C.Decreasing the temperatures of the reefs.
D.Controlling the ecosystems around the reefs.
2. What can we learn about the technology in paragraph 2?
A.It will be applied in a game.
B.It requires an expensive“cryomesh” .
C.It will be used to make a new“cryomesh” .
D.It requires the support of advanced devices.
3. What does paragraph 3 mainly tell us about the trials?
A.The time and place.
B.The range and way.
C.The effect and participants.
D.The equipment and conditions.
4. What is Jonathan Daly’s attitude to the technology?
A.Positive,B.Curious.C.Uncertain.D.Unconcerned.

【推荐2】Scientists say a huge percentage of bird species are in danger because their habitats, or homelands, are disappearing.

Traditional migration (迁徙) paths take birds through countries that are not protecting the places for birds to stop, rest and feed. The scientists studied the migration or flight paths of almost 1,500 species. They decided that 91 percent of them passed through dangerous areas.

The major danger for migratory birds is development. Buildings and pavements have covered the places where birds stop and feed as they move from one part of the world to another. One of the scientists who worked on the study says “Many of these important places have been lost to land reclamation because of urban, industrial and agricultural land expansion”.

The problem, according to scientists, is that many of these small birds die along their migration paths because they don’t have a safe place to feed and rest. There is no place to restore (恢复) their energy for the next part of their journey. Countries in North Africa, Central Asia and those along the coasts of East Asia are having the most difficult time in protecting land. The scientists say these countries do not have enough areas that are safe for birds. One species that doesn’t exist now is the Eskimo curlew. “Our world gets poorer every time we lose a species,” one of the scientists says.

The researchers say countries need to work together and come up with safe stopping areas for birds that pass through their boundaries. For example, one country might have preserved safe zones for migrating birds. But a neighbor country might not. A bird might die.

One scientist who is not connected with the report tells Los Angeles Times that while some habitats are changing, more work can be done to make urban areas safe for birds.

He says small changes, like planting more native plants or keeping cats out of the areas birds would be likely to use, could make a big difference.

1. The disappearance of the bird habitats is mainly caused by ________.
A.developmentB.the change of climate
C.filling seas to grow grainD.the loss of land and water
2. What do the underlined words “land reclamation” in Paragraph 3 mean?
A.Abusing the farming land.B.The disappearance of good land.
C.Causing the land quality to get worse.D.Making land suitable for farming or building.
3. Many birds die on the way of migration mainly because they ________.
A.are harmed by humansB.are killed by other animals
C.have to take a long journeyD.have no safe place to rest and eat
4. According to the researchers, how can we protect the migrating birds?
A.By keeping fewer cats or dogs.
B.By stopping the urban development.
C.By helping change the birds’ migration paths.
D.By preserving the local ecological environments.

文章大意:这是一篇说明文。主要介绍了科学家们发现了世界上已知的最大的海草场。他们使用一些不寻常的助手拍摄的视频来做到这一点:虎鲨。这项工作应该有助于保护海草,同时也展示了一种探索海洋的强大方式。

【推荐3】Scientists have recently discovered the world’s largest known field of sea grass. They did it using videos shot by some extraordinary helpers. The work should help protect the sea grass, and also shows off a powerful way to explore the ocean.

As a shelter for many sea creatures, sea grasses are flowering plants that normally grow in shallow waters near coasts. They grow in thick fields, known as seagrass meadows (海草床), which help clean the ocean water. More importantly, they are called “ocean lung”. They help in the fight against the climate crisis. That’s because they store huge amounts of carbon—the major source of global warming. Damaging these seagrass meadows can release this pollutant again, making things worse.

Considering the urgent need to protect seagrass meadows, scientists are eager to know about their size and number. However, the meadows can be hard to spot from above, either because the water is too deep or not clear enough. And the ocean is so huge that it’s hard to study them by diving. So scientists decided to have tiger sharks help the research.

Tiger sharks are inborn fast swimmers, and spend a lot of time in seagrass meadows. Between 2016 and 2020, the researchers attached cameras and other trackers to the fins of seven tiger sharks, and then let them go again. The cameras were designed to fall off after hours and float to the surface. Tracking signals helped find the floating cameras and collect the videos the sharks had taken while traveling for miles. Moreover, other tools were used, including satellite images, as well as images taken by divers and boats.

Putting all this information together, the scientists learned that the waters around the Bahamas are home to the largest seagrass meadow ever discovered. And the meadows cover at least 25,500 square miles, and could be as large as 35,500 square miles.

Different from previous studies, the program discovers how useful large underwater animals can be in helping to learn more about life under the sea. Oliver Shipley, a scientist from the team, says animals like tiger sharks are going to take us to new places that we didn’t know existed.

1. Why do seagrass meadows urgently need protection?
A.Damaging them will worsen climate crisis.
B.They determine the cleanliness of ocean water.
C.Sea creatures can’t survive without their shelter.
D.Their existence balances the underwater ecosystem.
2. How did tiger sharks help the scientific research?
A.By tracking signals scientists sent.
B.By bringing back cameras with videos.
C.By carrying the recording equipment around.
D.By spending a lot of time in seagrass meadows.
3. What is the highlight about the research according to the text?
A.Leading scientists.B.Advanced theories.
C.Multiple experimental tools.D.Unusual research assistants.
4. Which is the most suitable title for the text?
A.Man and Nature Work TogetherB.A Novel Way to Explore the Sea
C.Sea Grass: An Undervalued PlantD.Ocean Lung Measured by Natural Explorers
