1 . Earth Day is April 22. Every year, people around the world observe the day by helping to care for the environment. They carry out all kinds of activities in an effort to better the planet’s heath.

One way to support this goal is to grow plants native to your area. This helps wildlife like birds and insects that evolved alongside native plants. For many of these animals, plant pollen (花粉) is their food. Native pollinators often cannot recognize non-native plants as food. This means they do not collect the pollen or spread plants’ seeds. Planting non-native species creates so-called “food deserts” for pollinators including bees, birds, bats, butterflies and more.

Doug Taamy is a professor of entomology at the University of Delaware. Entomology is the study of insects. He found that non-native plant species can harm the natural food chain, which can lead to a collapse of the environment. “Plant choice matters,” he said. “The plants we choose to landscape our properties should be determined by how much life can live there.”

Humans depend strongly on insects. Without them, we would have no flowering plants, which would harm the food web that supports important animals. Birds, for example, depend on plants for food and spread their seeds while keeping the populations of harmful insects down.

Insects support plants that provide oxygen, clean our water, capture carbon and add nutrients to the soil. That builds topsoil and prevents flooding. Without insects, the biosphere — the living parts of the Earth — would rot because of the loss of insect decomposers. Humans simply could not survive that, Tallamy said.

In addition to providing food and habitat for insects and other wildlife, native plants are able to grow easily and do not require much care. That means less watering and less fertilizing. The situation is a win-win for gardeners and pollinators.

2 . A tsunami is a series of huge waves that can kill many people and destroy a whole country. A terrible tsunami disaster happened on December 26, 2004.     1     It is said that it might not be the worst and a future tsunami in the Indian Ocean could affect Singapore, Somalia, Western Australia, and many other places.

The word “tsunami” comes from Japanese words. A tsunami can be caused by natural phenomenon such as landslides, volcanic eruptions, large asteroid impacts (小行星撞击地球), and earthquakes occurring underwater or close to a body of water.     2    

A tsunami usually cannot be seen while it travels through deep water.     3     On December 26, 2004, some people saw the sea suddenly disappeared just before the waves came and knew that something was wrong. Some people managed to run fast from it and survived, but many people, who did not see any signs or did not run fast enough, died.

    4     If you are in a coastal area where the water suddenly draws back, the only chance of survival is to run for high ground or for the high floors of high-rise buildings. But because it moves too fast for people to run from it, only those who are lucky manage to survive.

Since the tsunami of 2004, many people know more about tsunami.     5    

3 . “What if we treat the ocean as if our lives depend on it? Or, what if we don’t?” World-famous marine biologist Sylvia Earle poses her famous “what if” questions to inspire people to reflect on how they can help save the ocean. In 1998, Time magazine named Earle its first “Hero for the Planet.”

Earle’s move to Florida’s west coast at age 12 is what started a lifelong passion. She says, “That’s where I first fell in love with the ocean.” In 1953, using newly developed equipment, the young scientist became one of the first in her field to scuba dive (水肺潜水). Her first long-term exposure to the ocean depths came in 1970 when she led an all-female research team to study the ocean. They lived under the sea in a submersible (潜水器) for two weeks. When they returned to the surface, world-wide cheer and praise were waiting, especially for Dr. Earle.

Sylvia Earle’s career includes many firsts. In 1979 she became the first woman to walk the ocean floor 381 meters below the surface. In 1990, she became the first female chief scientist of the U.S. National Oceanic and Atmospheric Administration (NOAA).

Through the years, Earle has spent roughly 7,500 hours underwater. During that time, she has become increasingly alarmed by the significant changes she has observed.

The famous scientist fears that the ocean is dying. Climate change, overfishing, the dumping of trash and chemicals and oil spills are just some of the many causes. In order to tackle the problem, Earle formed Mission Blue in 2009. This organization promotes the legal protection and conservation of the world’s oceans. Her plan is to develop “Hope Spots,” protected areas large enough to reverse (逆转) damage and restore the ocean.

4 . A Ghanaian man in Africa, who once made glass jewelry (珠宝), is now focusing on more than _________. The glass artist is reducing glass waste and helping his country both economically and _________.

Tetteh got to _________ the art of glass blowing (吹制) during a visit to Europe in 2012, then he became the nation’s only professional glass blower. Later, the beautifully-colored, artistic flower holders or water carriers really _________ him.

Why not _________ more Ghanaian people to make art pieces from glass? With efforts, Tetteh set up his own workplaces in Ghana where, every day, they _________ broken glass from waste centers and turns it into _________ for family use and decoration. Largely _________, after all, Ghana buys about $300 million yearly worth of glass and pottery from other countries.

Tetteh melts the _________ glass from old televisions or bottles and turns the old glass into hot liquid. Using a long pole to remove a ball of melted glass, he starts working to ____________ the glass into colorful items people can use again. Actually, In the past ten years, Tetteh’s ____________ has not only saved the country a lot of money but got the country ____________.

Tetteh, now 44, loves what he is doing. “Glass is my ____________, but Ghana is my heart,” he laughed, ____________ to do something for his country ____________.

Our world has been greatly affected by global warming and it is critical (关键的) that people, young and old, join hands to fight it. Most     1    (important), children today should learn to be eco­friendly at a young age.

It is believed that the nation should ask schools     2    (have) a class about “Green Living”. Every school should teach students to know about global warming and what they can do to reduce their carbon footprints. In the classes, students could be assigned to find several     3    (solve) to energy problems while learning about their effects     4     the earth. Students also should     5    (encourage) to use what they learned in class at home.

Too many people think that global warming is not a threat, but it is one of our     6    (big) problems. Steps     7    (take) to be “green” in the school are so effective. What would children be learning if the school’s lights were always left on and there were no recycling bins?

Green living and green schools are part of     8     new wave sweeping over the nation. How will our future leaders respond after years of living in a community     9     protecting our world’s natural environment just isn’t considered important？Schools and the government should teach young people to devote     10    (they) to dealing with global warming.

7 . On September 29, 2021, the US Fish and Wildlife Service declared it would be removing 23 species from its Endangered Species Act, including the ivory-billed woodpecker, various Hawaiian birds and freshwater fish, not because they had been pulled back from the edge of extinction, but because the USFWS believed these species would never recover, and were most likely extinct, therefore not requiring protection.

In April, 195 countries are getting together in China for a UN conference to discuss global agreements to protect nature and biodiversity, with the hope of finalizing an agreement to safeguard plants, animals, and ecosystems. However, the new strain (毒株) of Covid-19, Omicron, has potentially thrown the plans into a mess, and negotiators may switch to online talks if travel restrictions to China are put in place again.

“We can't go another four months without any progress” said Georgina Chandler, senior international policy officer at the Royal Society for the Protection of Birds. Conservationists are urging the talks to go ahead —   online if necessary — as the biodiversity crisis shows no sign of slowing up.

“Nature loss has not gone away and threatens both human lives and the global economy,” said Lin Li, director of global policy at the organization. “With one million species currently in danger of extinction, delaying action is not an option.”

Improving conservation and management of natural areas, such as oceans, forests, and wildernesses is crucial to safeguarding the ecosystems on which humans depend. However, forests are still being devastated, often for farming or commercial use. As trees absorb about a third of planet-warming emissions produced worldwide, stopping deforestation is key. At COP26 in Glasgow last November, world leaders plan to invest $19 billion in public and private funds to protect and restore global forests.

It’s easy to feel disheartened by the disappointing news, but the only way to stop more species suffering the same fate is to pay attention and take actions.

9 . If you’re not at least a bit terrified by the climate and ecological breakdown unfolding before our eyes, you haven’t grasped the scale of the crisis. Eco-anxiety, defined as “a chronic(长期的)fear of environmental doom”, is on the rise. But redirecting this anxiety into anger and collective action might just pull humanity back from the brink.

We don’t yet know how deeply eco-anxiety affects people, but we can learn not to repeat the mistakes of long-gone societies lost to environmental collapse. Jared Diamond’s Collapse: How Societies Choose to Fail or Succeed uncovers the common driver that led to the fall of ancient civilizations such as the Central American Mayan, the remote Pacific Easter Island, and the Mycenae: People accidentally destroyed the environmental resources on which their societies depended.

Today, we are living in a new climate and ecological age. The new normal is one that humans have never before experienced on earth, and that has occurred within a single generation. We can’t claim ignorance. Numerous scientific reports show: unprecedented(空前的)wildfires in the Arctic, heatwaves annually breaking records, the Amazon shrinking and drying, and species extinction rates accelerating. Nature’s dangerous decline is unprecedented.

So, it’s not surprising that eco-anxiety is on the rise. Anxiety is often a private emotional state: We feel alone, stuck inside our own heads, and our emotions stop us from doing the things we want. But anger, directed appropriately, can fuel powerful collective action for change.

We are on a pathway to destroy the global conditions for human survival. Unlike previous civilizations, we have the science and technology to understand our danger and chart a new pathway. This is a moment for all of us to channel our eco-anxiety, fear and anger into energy for change.

10 . Environmental pollution and other human activities are leading to thousands of deaths among seabirds, a new study has warned.

Ecological experts tracked the behavior of British and Irish seabirds. They used satellites to track hundreds of the creatures to find out where they went to catch fish at sea. The study can help assess potential impact from human activities and where protected areas of the seas should be.

Lightweight GPS tags were fitted to more than 1,300 adult birds from 29 different colonies around the UK and Ireland, including kittiwakes, shags, razorbills and guillemots. Results from the five-year study show the large areas of sea the four seabird species use. They found it was at least 600,000 square miles, an area three times the size of Spain. It shows how far they travel from their nests in search of food for their chicks. And it shows the use of the seas by all four species concentrated in the coastal waters of Scotland, highlighting the importance of conservation measures there.

The four species studied require conservation help, with kittiwake numbers declining 71 percent in the past 25 years and shag populations down 61 percent. This means both seabirds are "red listed" and need urgent protection. Razorbills and guillemots are "amber listed", which means they are considered to need conservation action.

Dr. Ewan, lead author of the research, said, “Many seabirds are at the top of the marine food web. They feed on some small fish but that prey is declining because of human pressures, including climate change. The result is that thousands of sea baby birds are dying each year because their parents can't feed them. For the first time, this study provides us with a full map for the feeding areas for some of our most important seabird species.”

The analysis provides critical data to inform marine management, the experts said.
