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(金属颗粒),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 and other technology products.

However, the scientists warn that mining for these nodules will cause irreversible(不可逆的) 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 DeepGreen, which aims to begin by 2024. It seeks to mine metallic nodules to be used in power systems for electric vehicles. DeepGreen Chief Executive Officer Gerard Barron defended the company's plans in reaction to the report. He said deep-sea mining offered the best alternative to surface mining, which has & 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.Permanent deal.D.Temporary stop.
3. What can we learn from Andrew Chin's words?
A.Conditions surrounding deep-sea mining are great.
B.The damage caused by nodule mining is reversible.
C.Nodule mining can cause harm in various aspects.
D.People sure less likely to be affected by nodule mining,
4. What's Gerard Barron's attitude towards deep-sea mining?
A.Opposed.B.Supportive.C.Ambiguous.D.Unconcerned.

REDUCING WATER POLLUTION IN THE LI RIVER

The beautiful Li River and its amazing surrounding scenery is one of the most well­known tourist destinations in China’s Guangxi Zhuang Autonomous Region. It attracts millions of domestic and foreign visitors each year. However, its reputation as a top destination has had negative effects on the river’s water quality. This report looks at the problem of water pollution and some actions that have been taken to deal with it.

Previously, water quality in the Li River had suffered greatly from an increasing volume of tourists, many of whom frequently threw garbage into the river. Many tour boats contributed to the problem too.

Kitchens on board were using lots of oil, which was often thrown into the water. The growth in tourism also meant the local population rose rapidly,as well as the number of commercial and industrial enterprises. Water pollution levels increased, with more household and commercial waste ending up in the river. In order to feed more people,more chemicals were used to increase crop production. These chemicals led to severe water quality issues,causing a decrease in the number of fish species. Local officials were concerned that the pollution was damaging the natural environment and felt that urgent steps should be taken to restore the river's original beauty.

A comprehensive initiative was started, with a number of measures that addressed the issues. The construction of waste water treatment facilities improved the water quality and water conservation.The collection and transport of household waste was also improved.Dozens of polluting enterprises were closed or moved. The local government set up strict regulations regarding further industrial development. New rules were also introduced regarding tour boat routes and garbage disposal methods. Furthermore, the local authorities began to use the media to spread environmental awareness and encourage greater use of clean energy. At the same time, they started to carry out inspections regularly and fine tourist organisations for abuse. With these measures,it is believed that the beauty of the Li River will be preserved for generations to come.

In addition,the ambitious “Water Ten Plan” is also now tackling water pollution across the country. Other initiatives,such as the “River Chief System”, hold senior officials responsible for reducing water pollution. With such campaigns in effect, China’s waterways are heading towards a clean and sustainable future.
1. What’s the passage mainly about?
A.The beauty of the Li River.

【推荐2】Imagine a world without insects. It might sound good at first without creepy-crawly bugs and annoying flies in your apartment. However, the consequences would be disastrous.

The number of insects has dropped by more than half in the past decades, according to British biologist Dave Goulson, author of Silent Earth: Averting the Insect Apocalypse. As insects make up most of the known species on this planet, this data is not good news, The Guardian reported on July 25.

Insects are indeed on the path to extinction, according to the first global scientific review of insect population decline, which was published in the journal Biological Conservation in January 2019. The researchers say intensive agriculture has been the main cause of the decline. Pesticides, in particular, destroy insect habitats. Urbanization and climate change are also significant factors.

“Unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades,” the researchers wrote in the review. “The repercussions (影响) this will have for the planet’s ecosystems are catastrophic to say the least.”

What would happen to Earth without insects? It’s almost impossible to predict, but the consequences would be far-reaching. We need insects to pollinate (授粉) crops, recycle plant and animal material, keep the soil healthy and much more. Without insects, many animals would have nothing to eat, and the predators of those animals would go hungry as well. The ecosystem would be thrown off balance.

“If insect species losses cannot be halted, this will have catastrophic consequences for both the planet’s ecosystems and for the survival of mankind,” said Francisco Sanchez-Bayo at the University of Sydney, Australia, one of the authors of the review.

The first step to halting this process is “to engender a society that values the natural world, both for what it does for us and for its own sake”, Goulson suggests. “The obvious place to start is with our children, encouraging environmental awareness from an early age.”

1. What does the underlined word “disastrous” in paragraph 1 probably mean?
A.Highly helpful.B.Very interesting.
C.Extremely terrible.D.Impossible to predict.
2. What is paragraph 3 mainly about?
A.Problems with intensive agriculture.
B.Causes of the decline in the insect population.
C.Factors causing insect habitat loss.
D.Influence of urbanization on insects.
3. Why are insects so important to Earth?
A.They help slow down climate change.
B.They reduce the number of predators.
C.They have a great impact on the ecosystem.
D.They keep the soil dry and healthy.
4. What does Goulson believe is key to preventing insect species losses?
A.Exploring the natural world often.
B.Providing insects with enough food.
C.Taking children to watch insects closely.
D.Raising public awareness of natural protection.

【推荐3】Looking for a fun World Earth Day activity? You may want to try plogging, or picking up litter while jogging. The new “sport” is becoming extremely popular with runners worldwide, many of whom are posting photos of themselves and friends holding bags of trash on social media.

Originated from the word jogging and “plocka upp”, a Swedish expression which means “pick up”, plogging is the idea of Erik Alström. In 2016, after moving to Stockholm, Alström became increasingly agitated at the amount of trash on the road during his daily bike ride to work. Since picking up litter while on his bike was hard to do, Alström began making the activity part of his daily runs. “I was shocked by the amount of junk along the way,” he said, “The same trash could remain on the road for several weeks without anyone picking it up, so I started picking it up.”

Other joggers soon joined Alström, and, by the end of 2016, the activity became so popular that official “plogging” events, with groups of runners entering, began appearing suddenly all across Sweden. As plogging began turning up on social media, the new “sport” started to spread beyond Sweden, first to other European countries and then worldwide. The official online “Plogga” group now has members from over 40 countries, all the way from the United States to Thailand and Ecuador. Many school running clubs are also getting in on the action, posting photos of themselves after going plogging together or holding competitions that reward the runner with the heaviest trash bag.

According to Swedish fitness app Lifesun, a person burns about 288 calories while plogging for half an hour. This is about 50 calories more than he/she would burn when just jogging. So, why not put on your running shoes, take a trash bag or two and make every day World Earth Day?

1. What can we learn about plogging from the text?
A.It was created on World Earth Day.B.It encourages people to run to work.
C.It is enjoyed by worldwide travelers.D.It is an environmentally friendly sport.
2. What does the underlined word “agitated” in Paragraph 2 probably mean?
A.Familiar.B.Doubtful.C.Upset.D.Interested.
3. What plays an important role in making plogging popular around the world?
A.The online group “Plogga”.B.The Internet.
C.The government.D.School clubs.
4. What does the author suggest in the last paragraph?
A.Making plogging a daily habit.B.Doing more exercise to burn calories.
C.Improving the environment every day.D.Celebrating this year's World Earth Day.
