3 . World Earth Day is on April 22. It's a day when people around the world work to help the planet, including kids. Here are what four kids have done for the planet.
Speaking Out
Jaysa Hunter-Mellers, 14, spoke at the City Hall to ask leaders to shut the last coal power station nearby which brought her an asthma（哮喘）attack. She didn't think that people would listen to her, a kid. But the coal power station later said it would close. Jaysa learned to speak to her local government at a young age and now she wants to teach others to speak up too.
Helping Butterflies
When Aiden Wang was 6, he learned that local butterflies were in trouble because they needed a kind of grass, milkweed, to survive. But milkweed was disappearing. So Aiden started growing milkweed in his house, on which the butterflies lay eggs. Aiden is now 13 and he cares for eggs and lets them go when they turn into butterflies.
Doing Good for Gorillas
When Addy Barrett was in the first grade, she learnt that the mountain gorillas were in danger. She wanted to protect them and set up a program called Gorilla Heroes. So far, Gorilla Heroes has raised more than $11, 000 to help mountain gorillas. Addy says, “The feeling of having a fine effect on the world is like no other. It feels so good to know that I am making a difference. ”
Educating the Youth
In the fourth grade, Jeremy Clark and Charlie Abrams saw a picture of the Statue of Liberty（自由女神像）up to her waist in water. It was meant to show what the statue would look like if all the ice in the world is turned into water. In 2019, they started a team called Affected Generation to urge young people to become climate activists. The two also want schools to teach about climate change.
1. Why did Jaysa call on the government to close the coal power station？| A．It made too much noise. | B．It caused health problems to her. |

| A．By collecting their eggs. | B．By feeding them on milk. |
| C．By turning eggs into butterflies. | D．By planting grass they lay eggs on. |

5 . Scientists are seeking new and creative ways to deal with climate change. As well as reducing our carbon dioxide sent into the air, scientists say we must remove the gas from the air to keep Earths temperature down.
One expert has now suggested pouring carbon dioxide into deep trenches (海沟), forming vast liquid lakes, Steve Goldthorpe, an energy analyst based in New Zealand, says the lakes could forever hold vast quantities of carbon dioxide. This is because once the gas reaches a depth of 3,000 meters it is denser (密度大) than water, meaning it naturally sinks to the seafloor.
“If liquid CO2 were to be placed in such a trench, it would be 7 per cent more dense than seawater and could remain forever as a lake of liquid CO2 on the ocean floor,” Mr Goldthorpe wrote in his paper, “the stored carbon dioxide could become solid over time, which would stop it mixing with ocean currents.”
Previously, experts have suggested burying the extra carbon dioxide deep underground, possibly in abandoned (废弃的) oil and gas fields. While first tests have shown that this method has potential, scientists are still unsure whether people would accept the fix.
Carbon dioxide lakes do form naturally in the cold, high-pressure depths of the ocean, but they are rare.
Researchers have previously given up the idea of ocean CO2 storage because it can make the water more acidic, which may affect ocean ecosystems. Mr Goldthorpe recognizes this in his paper, writing, “Any influence on deep ocean ecosystems would need to be examined.”
1. What is Goldthorpe’s way of fighting climate change?| A．To cut down carbon dioxide sent into air. |

| A．natural storing places rarely exist |
| B．many oil and gas fields will have to be abandoned |
| C．scientists are unsure whether people would accept the fix |
| D．there are concerns on possible damage to the ocean ecosystem |
| A．doubtful | B．cautious |
| C．disapproving | D．determined |
| A．Health. | B．Education. | C．Environment. |
7 . Indian scientists plan to add substances to clouds above the capital New Delhi in an effort to produce rain to reduce pollution. The method is called cloud seeding. The process involves adding different chemicals to clouds to cause rain. When rain falls from the sky, water droplets can attach to pollution particles and bring them down to the ground.
New Delhi has been rated the city with the most air pollution in the world. Air quality decreases in the city ahead of winter each year. During this time, cold air can trap many pollutants, including gases from vehicles, industry and agricultural burning.
Scientists expect some clouds over the city around November 20. They hope the clouds will result in heavy rainfall. The project, estimated to cost $120,000 for 100 square kilometers, would involve spraying into clouds a mix of salts that include silver iodine.
“The local government in New Delhi, a city of 20 million people, has already closed all schools and other educational institutions, asked people to work from home, restricted the movement of trucks and other vehicles and ceased all building activities”, said Gufran Beig, head of the Indian government’s air-quality measuring agency SAFAR, adding that “The city needs heavy and widespread rain to wash away the pollutants, and light rain could worsen the situation.”
New Delhi’s pollution has been exacerbated by more than 3,500 fires in Punjab and Haryana, where farmers burned stubble (秸秆) ahead of sowing their winter wheat crop. The smoke has been trapped tightly in the cold winter air, leaving the hospitals filled with children and the elderly.
It is reported that officials in New Delhi now are seeking approval for the project from the Supreme Court. In 2021, a plan to seed clouds over the mountains of New Mexico to increase snowfall was pulled because of the blame that it could poison people and the environment. As a matter of fact, several countries have used this method to produce rain, improve air quality and water crops in times of extreme dryness, including Mexico, the United States, Indonesia and Malaysia.

10 . The softshell turtle species is officially listed as endangered by the IUCN Red List. Scientists long thought softshell turtles were extinct in the Cambodian part of the Mekong River until they discovered some stragglers (掉队者) in the early 2000s.
The species had quite a wide historical range across Asia, but much of that range is now completely gone. Much of the turtle’s habitat in Southeast Asia have disappeared due to urban and industrial development along the Mekong River. The sand where turtles multiply is routinely carried away for use in construction projects, while fishing nets lift up hatchlings. People also take turtles and their eggs to sell for food.
Initial surveys in 2003 and in 2007 found two small populations of the softshell turtles along a 30-mile stretch (水域) of the Mekong River. Since then, conservation groups have worked with local communities and officials to increase the wild population of these endangered turtles, including a program to hire former egg collectors to help search for and protect nests instead of harvesting the eggs.
For the last decade, WCS, Conservation International, the Turtle Survival Alliance and local groups have worked to protect turtle nests. Their goal is to ensure eggs will multiply and hatch, and that baby turtles grow strong enough to eventually take care of themselves in the wild.
A team recently released 150 hatchlings back into their natural habitat, bringing the total to more than 7,700 baby turtles in the past 10 years.
