Around the world, coral reefs (珊瑚礁) are in danger. Now, let’s check out a few ways conservationists are protecting these habitats.
Seaweed Smackdown
Hot ocean temperatures can supercharge seaweed growth — and that’s not good for a reef. So, in Hawaii, scientists have used an underwater vacuum (真空吸器) to suck up lots of seaweed into the device’s long tube. In Australia, scientists are studying a low-tech solution: pulling seaweed by hand.

Some polyps (珊瑚虫) are harmed by heat waves and pollution. Scientists cut parts of coral from a healthy reef. Then these polyps are taken to a nursery, which could be in shallow protected areas underwater. After about a year, the healthy coral parts are attached to damaged reefs. The nursery-grown corals can bring new life to a struggling habitat.
Sound Saver
Healthy reefs are noisy. Fish make different sounds, and thousands of shrimp create and pop bubbles with their claws to create a sound. The biologists play sounds of healthy reefs through underwater speakers. They found that six weeks of broadcasting healthy reef sounds doubled the amount of fish in the area.
Bleaching Killer
One of the biggest threats to coral reefs is bleaching. Here’s how it works.
Thriving coral Most coral species survive by partnering with tiny algae (藻类), which make food for the coral by changing sunlight into sugar. | Under stress But when the ocean water gets too hot, the algae produce too much oxygen, which can hurt the coral. | Bleaching So corals kick out the algae. As the algae leave, the color disappears and the coral appears to turn white. This process is called bleaching. |
Biologists have discovered that many corals in the Red Sea have a species of algae in their tissue that’s found nowhere else, so they can survive heat waves. Biologists hope their work will inspire governments and environmental groups to protect these corals.

【推荐1】At the age of 50, Nina Schoen expects to have a long life ahead of her, but has thought a lot about death—and why people are so reluctant to talk about it: “It’s going to happen to all of us,” she says, “but it should be a more positive experience than the fear we put into it.”
When she first heard about a new end-of-life process that turns the body into compost (堆肥), “I was really moved by the idea,” says Schoen, who became one of the first to reserve a spot with a Seattle-based company called Recompose, the county’s first funeral home to offer human composting.
Last year Recompose began transforming bodies to soil, more formally known as natural organic reduction. Before that, end-of-life options in the U.S. were limited to burial or cremation (火化), both of which come with environmental costs—U.S. cremations alone dump 1.7 billion pounds of carbon dioxide into the atmosphere every year.
Katrina Spade pioneering the composting movement has spent a decade developing the process in hopes of offering people a greener option for death care. “I wondered, ‘What if we had a choice that helps the planet rather than harms it?’” Spade tells PEOPLE. “To know that the last gesture you’ll make will be gentle and beneficial and it just feels like the right thing to do.”
After she had her own two sons, she began to wonder what she might do with her body after death. A friend who knew her interest in the topic reminded her that farmers sometimes compost the body of cows, and that sparked an idea for her theory: “If you can compost a cow, you can probably compost a human,” she thought, and she set about designing a facility to do just that.
“This is about giving people another choice,” Spade says. “At first, people react with shock—‘You really can do that?’ But so many people today are looking at their impact on the Earth. This is a popular thing because when you die, you can give back to the planet.”
1. How do people react when it comes to death according to paragraph 1?A.They are unwilling to comment. |
B.They can face it without fear. |
C.They feel it a positive experience. |
D.They would like to compost their bodies. |
A.Its CEO is Katrina Spade. |
B.It is located in Seattle. |
C.It was founded to resist cremation. |
D.It has spent 10 years composting bodies. |
A.Changed. | B.Compromised. |
C.Quitted. | D.Inspired. |
A.A little things in our life can bring in big outcomes. |

C.Composting is so popular that we should reserve a spot soon. |
D.We should reject burial because of its harm to environment. |
【推荐2】Kiribati is a South Pacific nation of 33 islands along the equator(赤道). It gained its independence from the UK on July 12, 1979. The International Date Line runs through this country. People here are always the first to see a new day. However, this Pacific Island nation may be the first country to disappear under the rising sea levels of climate change.
As our boat nears the shore, the dark shadows beneath the sea sharpen into focus. Coral stones, organized neatly into rows, glisten from the reef of this shallow bay. We are drifting over the foundations of the neighborhoods of Tebunginako. The village was once home to more than 200 households, but today, it lies beneath several meters of water.
“We used to swim out there to see the ships when we were boys. They’d tie them up to the coconut trees just over here,” explains the Mayor, pointing enthusiastically as we coast over the remains of his town. Locals say Tebunginako was once the island’s main harbor—before the rising sea swallowed its coast.
Many of Kiribati’s citizens have escaped to the capital island, South Tarawa, due to climate related disasters. Objectively, developed countries should be responsible for global warming. Like any other developing island state, the fresh water supply here is being strained. The Mayor adds.“ “Climate change and the rising sea worsen a problem we already have concerning our water resources.” A teacher approaches and complains. “We are very simple people with very simple needs, but we do not want to be faced with something that is not entirely of our own doing.”
As the sun sets in Tebunginako, the Mayor guides us to the shore of the town’s two remaining structures, a Church and a traditional community center. The Mayor states, “These places are important to our people because of their religion and because it was the last place they were all together.”

【推荐3】Margaret is a famous climate activist (气候活动家). When she was thirty- two years old, she created an Egyptian charity organization called the Green Generation Initiative (倡议), which has been planting trees and countering the acts of cutting down the forests at will and climate change in the North African nation since 2013.
GGI’s primary focus is on developing young climate activists through environmental education in schools and addressing food unsafety in the area through planting fruit trees.
Over 120, 000 trees have been planted in Egypt since GGI’s start and they have recorded a survival rate of over 90 percent, while thousands of schoolchildren have chosen to plant trees to make sure that they learn the importance of acting as a guardian over the health of the environment.
Speaking to world leaders at the United Nations Climate Change Conference in Glasgow, Margaret issued a warning on the harm of climate change, “Over 1 million of my fellow Egyptians are facing climate related hunger. In 2024, half of the world’s population will be short of water. By 2030, the climate problem will make about 50 million people in Sub- Saharan Africa homeless.”
Margaret added, “I have been doing what I can. I was inspired by the great Maathai, who called on thousands of women and men to plant tens of millions of trees throughout Kenya. Her approach was practical and deeply ecological (生态的). She was the first African woman to win the Nobel Peace Prize. I started a tree growing initiative that raised the awareness of food safety for young Egyptians. So far, we have grown 30, 000 fruit trees, providing badly needed food for thousands of children. We are the adults on the Earth right now, and it is our responsibility to ensure that the children have food and water.”

【推荐1】The pandemic has been particularly hard on people working for tips. Some haven’t been able to do their jobs at all while others don’t interact with customers the same way. Just as many services have changed, so should tipping. Some old standards no longer seem fair, and several newer ones will apply long after the pandemic is over. As for specific situations, here’s what the experts recommend:
FOOD AND DRINKS
Restaurant workers
OLD RULE:Leave a tip only when you dine in.
NEW RULE:Always tip, even for takeout.
TIP: 15 to 20 percent when you dine in, and 10 to 15 percent on takeout or delivery orders.
HOME DELIVERIES
Package delivery drivers
OLD RULE:Don’t tip.
NEW RULE: Show appreciation if you get deliveries more than once a week.
TIP: Drinks, snacks, or $5 to $20 if a package is particularly heavy or large. Postal workers cannot accept cash or gifts worth more than $50 per year. UPS tells drivers to decline tips unless a customer insists. And FedEx bans employees from accepting cash or cash equivalents (such as gift cards).
PERSONAL SERVICES
Ride-share drivers
OLD RULE:Tip in cash.
NEW RULE:Ask your driver. The Lyft and Uber apps let you add gratuities, but some drivers prefer cash.
TIP:15 to 20 percent.
Hotel housekeepers
OLD RULE: Tip at the end of your stay.
NEW RULE: Many hotels now do housekeeping by request only, so tip every time you ask them to come.
TIP:A few dollars per night, plus $5 for any extra requests, such as asking for additional toiletries.
Next time, you’re unsure whether a tip is in order, follow this simple rule: When in doubt, tip. “Tipping well is one way to make things easier for someone else.”
1. According to new rules, which of the following cannot get tips in cash or similar things?A.A restaurant waiter. |
B.A FedEx deliverer. |
C.A Lyft driver. |
D.A hotel housekeeper. |
A.Paying 22 dollars through the app. |
B.Leaving a gift card. |
