Kilauea has been erupting almost without stopping since 1983. It is one of the world’s most     1     (close) observed volcanoes. Most of these observations took place at the Hawaiian Volcano Observatory on Kilauea’s highest point, from     2     researchers now have to withdraw. But the     3     (late) eruption is one of the biggest and could provide scientists     4     a lot of new information.

Scientists from the Hawaiian Volcano Observatory and University of Hawaii are studying     5     the molten (熔化的) rock beneath the earth flows through a series of cracks (缝隙) under Kilauea before     6     (send) flying into the air. They want to learn what warning signs may exist for future eruptions to better protect Hawaii’s     7     (community).

Hundreds of small earthquakes caused by the eruptions have damaged the structure of the Hawaiian Volcano Observatory. So the scientists were forced     8     (take) the equipment and records out of the building and moved     9     (they) to the University of Hawaii. The records include     10     (science) information and photos that are more than 100 years old.

Wetlands are the link between the land and the water. They are transition zones where the flow of water, the cycling of nutrients and the energy of the sun meet to produce     1     unique and special ecosystem     2     (characterize) by hydrology, soils and vegetation—making these areas very important features of a watershed. The water is often groundwater,     3     (spill) up from an aquifer or spring. A wetland’s water can also come from a nearby river or lake. Seawater can also create wetlands, especially in coastal areas that experience strong tides. Here is one in China.

The National Nature Reserve of Guangdong Nanpeng Islands in Guangdong Province was established in 2003. It     4     (cover) a total area of 35,679 hectares. It became the fifth national-level marine nature reserve in Guangdong, as well as the first one in the eastern region of Guangdong, in 2012. In 2015, it     5     (recognize) and included in the International Important Wetlands Directory.

The main focus of the reserve is to protect the unique underwater natural landscapes, the ecosystems of the nearby     6     (coast) waters, the rare and endangered marine animals, the various fish species and their habitats, as well as the marine biodiversity.

Researchers have discovered 1,308 marine species in the area, including 772     7     (economic) significant fish, shrimp, crab, mollusk, and algae species. The reserve is home     8     more than 21 identified rare and endangered wildlife species in water, among     9     nine species such as the Chinese white dolphin and the nautilus are classified as first-class protected animals at the national level, while     10     (variety) of other 27 species, such as the common bottlenose dolphin is classified as second-class protected animals.

5 . According to a new USDA(the U.S.Department of Agriculture)report,U.S.forests could worsen global warming because they are being destroyed by natural disasters and are losing their ability to absorb planet-warming gases as they get older.The report predicts that the ability of forests to absorb carbon will start declining after 2025 and that forests could release up to 100 million metric tons of carbon a year as their emissions from decaying(腐烂)trees go above their carbon absorption.Forests could become a“substantial carbon source”by 2070,the USDA report says.

The loss of carbon absorption is driven in part by natural disasters such as wildfires, tornadoes and hurricanes,which are increasing in frequency and strength as global temperatures rise.The disasters destroy forestland,destroying its ecosystem and decreasing its ability to absorb carbon,according to Lynn Riley,a senior manager of climate science at the American Forest Foundation.Aging forests also contribute.The report found that older,mature trees absorb less carbon than younger trees of the same species,and U.S.forests are rapidly aging.

This trend is likely to continue,as forests come under increasing threat from climate change and exploitation(开采).The typical tropical forest may become a carbon source by the 2060s,according to Simon Lewis,professor in the school of geography at Leeds University. “Humans have been lucky so far,as tropical forests are cleaning up lots of our pollution,but they can’t keep doing that indefinitely,”he said.“We need to cut down fossil fuel emissions before the global carbon cycle starts working against us.”

U.S.forests currently absorb 11 percent of U.S.carbon emissions,or 150 million metric tons of carbon a year,equal to the combined emissions from 40 coal power plants,according to there port.The loss of forests as natural carbon absorbers will require the U.S.to cut emissions more rapidly to reach net zero.“As we work to decarbonize(碳减排),forests are one of the greatest tools.If we were to lose that tool,it means we will contribute that much more in emissions,”Riley said.

9 . Every year the start of the Atlantic hurricane season is another reminder for Margarite August that she still doesn’t have a roof.

The 70-year-old retired teacher’s home on the small Caribbean island nation of Dominica was mostly wiped out by hurricane Maria six years ago.

Six years after hurricane Maria, Dominicans like Margarite August still haven’t been able to rehabilitate their homes.

August is not alone. Since Maria, the government of Dominica has built 7,000 new homes—about a quarter of its housing stock-with materials to fight another Category 5 hurricane. They’ve also relocated two communities. But an untold number of the island’s 70,000 or so residents are like August, rebuilding their homes in any way they can afford.

Hurricane Maria is often referred to as a once-in-a-lifetime disaster. Scientists put much of the blame on warming ocean temperatures that could make frequent (频繁的) storms like it.

Maria damaged a terrible 95% of Dominica’s housing stock and 226% of the nation’s GDP. Before the storm, the country’s economy had long struggled since its independence from Great Britain in 1978. Unlike its more famous touristy neighbors along the chain of eastern Caribbean islands it lies on, Dominica is more known for its rugged mountains and jungles (丛林) than white sandy beaches.

The jungle mountains that crash down to the coast are beautiful but disasters visit easily. “I don’t think anybody ever got over Maria,” says Christine John of the Dominica Red Cross. “There are a lot of persons today—if it just starts to rain outside, they get anxious.”

10 . Almost a quarter of the UK’s sea swimmers may not swim in the ocean this year because of sewage (污水) dumping by water companies, according to a poll (民意调查). Sewage was dumped into waters near England’s most celebrated beaches for nearly 8,500 hours last year. And there were 1,504 discharges (排出) in 2022 on beaches supposed to be free from such pollution.

The poll spoke to 2,272 UK adults between 21 and 23 on July. Just over 30% said they typically went sea swimming during the summer, and of these 23% said they would not this year because of sewage dumping by water companies. More than two in five of the regular beachgoers also said they were less likely to visit the British seaside this summer because of sewage discharges.

The Department for Environment says government should allow the Environment Agency to charge unlimited fines on rule-breaking water companies. Fines are currently capped (上限) at £250,000. The Department for Environment has been calling for a sewage tax on annual profits and a ban on bonuses of water company managers. “Coastal communities are at the mercy of water companies who unapologetically discharge raw sewage into popular swimming spots,” Tim Farron, the Department for Environment’s spokesperson said. “The government needs to stop letting water companies off the hook and finally ban these terrible sewage discharges and defend our tourism sector.”

A Water UK spokesperson said standards at beaches had greatly improved since the 1990s but that the industry recognized it had been slow to deal with the harm to our seas caused by sewage overflows. “Over the next seven years, water and sewerage companies plan to spend £10bn—doubling current levels of investment—on sewage treatment,” they said. “As part of this, bathing waters will be among the first to receive funding.”
