“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.

1. Why does Sylvia Earle put forward “what if” questions?
A.To call on people to protect the ocean.
B.To stress our dependence on the ocean.
C.To criticize people’s damage to the ocean.
D.To contribute an article to Time magazine.

文章大意:这是一篇新闻报道。文章主要介绍了联合国的一份新报告称,化石燃料的开采量仍然很大。并介绍了如何缩小开采量,以便有机会将气温上升限制在1.5度以内。

【推荐1】The world’s nations have promised to limit global temperature increases to 1.5 degrees over pre-industrial levels, which involves shutting down fossil fuel extraction (化石燃料开采) as quickly as possible. But despite this promise, first reached six years ago during the Paris Climate Accords, the fossil-fuel producing nations are on track to extract more than twice as much coal, oil and natural gas as would be permissible under this plan, a new United Nations report says.

To have a chance of limiting temperature increases to 1.5 degrees, production of coal needs to drop by 11% every year between 2020 and 2030. while production of oil and gas needs to drop by 4% and 3%, respectively, the report finds. Instead, production of oil and gas is set to increase, while coal production is projected to drop slightly.

The so-called production gap, the difference between countries’ climate promises and their fossil fuel production plans — hasn’t changed since the United Nations first examined it in 2019, indicating that international climate accords are still closer to theoretical promises than detailed plans.

The report looks at fossil fuel production in 15 countries — including Australia, Brazil, Canada, India, the U.S. and the United Kingdom — hat are collectively responsible for three-quarters of the world’s fossil fuel production. Most of these countries have promised to reach zero emissions by mid-century, but they are planning to increase their fossil fuel extraction until at least 2030.

So far, climate efforts from major fossil fuel extractors, including industry, have “focused on extracting fossil fuels in less-polluting ways, not on winding down production levels in line with climate goals,” the report says. While these efforts, such as developing carbon-capture (碳捕捉) technology and reducing methane leaks (甲烷泄露) are important. they fall far short of the changes science demands if global temperatures are to stay at a livable level.

To close that gap, the report urges governments to make realistic plans for winding down fossil fuel extraction, starting with state-owned companies, which arc responsible for more than half the world’s extraction of such fuels.

1. What does the new United Nations report say?
A.Climate promises are being made worldwide.
B.Fossil fuels arc being extracted in large quantities.
C.Global temperature will soon increase by 1.5 degrees.
D.Production of coal will drop sharply in the next decade.
2. Why are the figures mentioned in paragraph 2?
A.To imply an energy crisis.
B.To show the efforts made by now.
C.To indicate how to close the production gap.
D.To stress the goal of the Paris Climate Accords.
3. What can we say about most of the 15 countries?
A.They will achieve zero emissions by 2030.
B.They think little of carbon-capture technology.
C.They should turn to the United Nations for help.
D.They are on the way to breaking their promises.
4. Which should act first to bring us towards a livable climate future?
A.Coal mines owned by the government.B.Gas stations run by private companies.
C.Power plants owned by the government.D.Car factories run by private companies.

【推荐2】More than half of the birds in Washington are at risk of extinction because of climate change. That's according to a new national report from the Audubon Society, which gives detailed analysis of climate effects on about 600 species of North American birds.

It's based on more than 140 million observations of birds across the US, Mexico and Canada. Audubon scientists looked at the likely effects of sea-level rise, urbanization, drought, extreme spring heat, increased fires, heavy rain and other factors.

But it doesn't just spell out a doomsday scenario (世界末日).Instead, it offers a range of effects and warming, depending on how much carbon humans add to the atmosphere.

"It is truly an existential threat (威胁), not only to birds but to people,” said Doug Santoni, board chair of Audubon Washington, who looked into the report as soon as it came out.

Santoni says he was struck to see the vulnerability (脆弱)of a common “ backyard bird" , the dark-eyed junco. It's one that many first-time birders become familiar with as they learn how to identify species based on their markings and other traits. Currently in Washington, you can count on juncos to show up at your feeder, year round. Extreme spring heat, increased fires and heavy rain are the kinds of changes that will force birds like these north, or kill them off if they fail to adapt.

Trina Bayard, director of bird conservation at Audubon’s Washington chapter, says, "It's certainly a very serious warning report," but adds that there’s still hope. “If we can stabilize current temperatures and decrease our emissions (排放), we can really reduce the effects to these birds …that's very motivating. ”

1. What can we know about the new report?
A.It analyses the species of birds in detail.
B.It's issued by watching 600 bird species.
C.It shows the end of North American birds.
D.It reports the threat some birds are facing.
2. What may Santoni probably agree with?
A.Climate change is a threat only to birds.
B.It's too late to take action to save the birds.
C.The current situation of the birds is worrying.
D.It's common that birds are affected by climate change.
3. Which of the following can help these birds according to Trina?
A.Lowering present temperatures.
B.Reducing our daily emissions.
C.Making them adapt to climate change.
D.Encouraging people to protect them.
4. What can be the best title for the text?
A.Climate change threatens many Washington bird species.
B.A new report about 600 species of North American birds.
C.Different attitudes towards the situation of bird species.
D.Climate change makes different kinds of species at risk.

文章大意:本文是说明文。讲述了美国食物浪费问题,并呼吁消费者开始采取行动去避免食物浪费。

【推荐3】In the United States, people generate approximately 35 million tons of food waste every year, and as individual families, they waste about 30 percent of the food we buy. For the average four-person household with a monthly food budget of $1,000, that’s like throwing $300 straight into the garbage every month.

It’s not just the personal budgets that are affected by food waste, either - it contributes to the ongoing climate crisis as well. The yearly amount of water and energy wasted from uneaten food in America every year would be enough to power 50 million homes, and the amount of greenhouse gases produced from food waste was equivalent(相等的) to the carbon dioxide emissions of 42 coal-fired power plants, according to a 2021 report from the U.S. Environmental Protection Agency.

At home, the core issue is that people buy too much food and then throw so much out because the ingredients “do not match food preferences”,according to a 2020 report from the National Academies of Sciences, Engineering and Medicine. It’s true that there are far more factors that contribute to waste within the food system than just the consumer behavior.“It’s so much bigger than a consumer problem,” said Pamela Koch, associate professor of nutrition education at Teachers College, Columbia University. But that doesn’t mean the personal efforts can’t still have an impact. “There’s so much that consumers can do," said Roni Neff, associate professor of environmental health and engineering at Johns Hopkins University’s Bloomberg School of Public Health.

The process starts with “recognizing what we’re throwing out and what led to it,”Neff said. “If we understand our own patterns and what’s going on in our homes,” she continued, the next step is“figuring out how to set up the environment to make it as easy as possible to avoid food waste.”

1. What is the purpose of using figures in Paragraph 1?
A.To attract more cleaners.
B.To show the richness of food.
C.To tell the seriousness of the food waste.
D.To introduce the size of individual families.
2. What is the result of food waste?
A.Improving the climate crisis.B.Reducing the personal budgets.
C.Increasing the greenhouse gases.D.Changing coal-fired power plants.
3. What can be inferred from Paragraph 3?
A.Food system works well.
B.Food preferences are easy to satisfy.
C.Consumer behavior has been improved.
D.Personal efforts are encouraged to save food.
4. What is the best title of the text?
A.Fight against Food WasteB.Study of Food Production
C.Save Money in Daily LifeD.Ways of Protecting the Environment
