5 . Wondering what you can do to celebrate Earth Day on April 22? You’ve come to the right place. We’ve gathered a comprehensive list of Earth Day activities, both fun and environmentally-conscious, to help raise awareness and make a difference. If you’re ready to learn more about joining the global celebration, initiating real change, and doing your part to save our planet, read on!
·Walk or ride your bike.
·Use a refillable water bottle.
Consider going with a stainless-steel refillable bottle for a super long-lasting option.
·Plant a tree.
Pick a tree species that’s native to where you live. If you’re unsure, ask an employee at your local nursery or garden department. Choose the best planting spot to meet the tree’s needs, dig a properly sized hole, and water the tree well to give it a good start.
·Visit a local farmer’s market.
Eating locally grown food is much better for the environment. For example, locally-grown food doesn’t have to be transported long distances to end up on grocery store shelves.
·
See if your community is holding an environmental fair. If your community doesn’t have one planned, consider starting one yourself! It’s the perfect day to get together for a fun and educational celebration of the Earth. Any money raised can go towards a local environmental restoration project or group.
| A．Attend a local Earth Day event. |
| B．Educate your community on environmental awareness. |
| C．Going car-free for the day will reduce harmful carbon emissions. |
| D．That means your money won’t be wasted on unnecessary spending. |
| E．If physically doing this is unrealistic for you, there are other choices! |
| F．Normally, plastic water bottles end up in garbage cans after a single use. |
| G．You’ll also be giving back to your community by supporting local farmers. |
6 . Each spring, millions of people take photos among the famous cherry trees around the Tidal Basin in Washington DC-some even get married there. That’s what Jody Axinn did 10 years ago.
“Now, the romantic spot is unrecognizable. The whole section is under water,” says Axinn who is revisiting the cherry trees with her family. “When I got here 10 years ago, the place was flooded regularly, but certainly not twice a day, every day.”
There are two forces working together to affect the Tidal Basin, the trees and monuments around it. The seawall around the basin, built with mud dug up from the Potomac River bottom, has sunk about five feet over the past century.
“At the same time, the water level in the basin has gone up by more than a foot because of climate change,” explains Leslie Frattaroli, manager of the National Park Service (NPS). “The Tidal Basin looks like a small lake, but it’s actually part of the Potomac River, because there are gates at the upstream and downstream ends of the basin that allow river water to rush through. Therefore, it is gradually rising along with the level of the world’s oceans.”
Combining these two factors, the water is six feet above where the seawall was originally designed to keep it out. Later this spring, the park service will start to raise parts of the walkway around the basin and along the Potomac River.
“It would be impossible to complete the $113 million project without removing the cherry trees along the water,” Leslie says. “The good news is that when the project is completed in 2027, 274 new cherry trees will be planted.”
Among the trees to be removed is a very famous little tree known as “Stumpy”. At high tide (潮汐), the base of the tree is flooded. Although it is in extremely bad conditions, its remaining three or four small branches burst into flower each spring, with the Washington Monument standing tall in the background.
1. What can be learned from Jody Axinn’s words?| A．The famous cherry trees should be protected. |
| B．The flooding around the basin is more serious. |
| C．Getting married at the Tidal Basin is unpopular. |
| D．Washington DC has changed beyond recognition. |
| A．The sinking seawalls. | B．The rising sea level. |
| C．The beautiful scenery. | D．The warming climate. |
| A．too small to hold the water | B．a small inland lake |
| C．at the downstream end of a river | D．connected with the oceans |
| A．It is not in harmony with the scenery. | B．It is in very bad conditions. |
| C．It happens to be in the reconstruction area. | D．It is attracting too much attention. |
7 . “Earth” has always been an odd choice of name for the third planet from the Sun. After all, if an alien examines it through a telescope, he would note that two-thirds of its surface is covered not by earth at all, but by oceans of water.
However, most of the oceans on Earth remain unexplored. For example, photographers are fond of pointing out that scientists have mapped nearly all the oceans’ surface, but less than a quarter of the seabed. Biologists think the oceans might host more than 2 million species of animals, of which they have so far identified perhaps a tenth.
A new project may change this. Launched in London on April 27th, 2023, Ocean Census aims to discover 100,000 new species of ocean animals over the coming decade. Its first ship, Kronprins Haakon, set sail on April 29 for the Barents Sea.
The project is launched for two reasons. One is that the longer scientists wait, the less there will be to study. “Top on our agenda are species thought to be in the greatest danger from climate change,” says Oliver Steeds, founder of the project. “Otherwise, the forest is burning down and we won’t know what was there before it is lost.”
The second reason is technological. Biologists find about 2,000 new species a year, a rate hardly changed since Darwin’s day. Ocean Census is betting that it can go faster. Fancy cameras on remote-operated vehicles, for instance, allow scientists to scan deep-sea creatures such as jellyfish without removing them from their habitat. Just as the huge pressures of the deep sea are deadly for humans, taking such a jellyfish to the surface for examination may reduce it to gooey slime (黏液).
Exactly what the new effort might turn up, of course, is impossible to predict. But history suggests it will be fruitful. Half a century ago, scientists discovered hot seabeds that were home to organisms living happily in conditions that, until then, had been thought harmful to life. These days, such hot seabeds are thought to be one possible candidate for the origin of all life on Earth.

Bill McDonnell, who was a soldier when young, was a 92-year-old now, still healthy and strong. He loved hunting very much. On December 15, Bill decided to go hunting in Shenandoah Mountain the next day as the deer season had begun. His wife Joanna McDonnell intended to let their son Bill McDonnell Jr. accompany him, but Bill Jr. had a football game that day. Bill McDonnell said he could manage all by himself. Joanna then required Bill to be out of the woods by 2 pm and home by 3 pm, plenty of time before sunset. She added, “ Do take some necessities like a flashlight, just in case.”
The next morning, Bill woke up at four, grabbed his muzzleloader (前装枪), and steered his Jeep toward Shenandoah Mountain. At the end of the old Laurel Run logging road, he began to walk. It was about 7:30 am and 25 degrees when the sun peeked through the trees.
Not long into the hike, he came upon a path he didn't remember. Maybe this was a secret route to the king of all bucks (雄鹿). He took it. Then, around 11 am, he came into a clearing (林中空地) along a ridge line (山脊线). He had walked farther than he had expected. It seemed that his path up the mountain had meandered quite a bit. “Where am I now?” he muttered. Bill figured he could drop into the valley, hunt a bit and then go back home. But when he snaked down through the forest, he found there was no path at all. The forest was thick. It was hard to tell the direction now.
By around 2 pm, Bill stopped at somewhere in the valley, exhausted. “I’ll get it figured out,” he said to himself. He took out his phone to call his wife, but the phone had died. He dug into his pants for the GPS device he always brought in case of emergency and pushed the “on” button. Nothing. He had forgotten to charge it the night before.
“No, I’m not lost,” he told himself. His eyes caught a stand of tall trees. He remembered admiring the line of fantastic oaks and pines earlier. Reach them and the car wouldn’t be that far off. It meant he would have to cover some ground.

Despite the difficulties, the California coastal ecosystem is improving, largely thanks to the huge appetite sea otters (海獭) have for crabs. In a creative study, scientists revealed the return of otters to their former habitat in a Central California river mouth has slowed the decrease of the area’s river banks by up to 90%. “It would cost tens of millions of dollars for humans to rebuild these stream banks and restore these rivers. The otters are stabilizing them for free, in exchange for an all-you-can-eat crab feast,” said biology professor Brian Silliman, Ph. D. at Duke University.
Like many California river mouths, Elkhorn once was a habitat for otters, which need to eat around 20 to 25 pounds of food every day, with crabs being one of their favorite meals. But after fur traders hunted the local otter population nearly to extinction, the number of crabs exploded over the next century. Crabs dig into salt river soil, and over time can cause a salt river to wear away and collapse. Today, years after the otters returned, rivers and stream banks became more stable.
Angelini, one of the study’s authors, said that tool is an encouraging sign for her team as they face similar threats to Florida’s coastlines from sea level rise, storms, and extra nutrients overflowing into coastal waters. “All these seem unsurmountable,” Angelini said. “However, this study shows that, if we truly understand the ecosystem and know what tools to use, we can see significant benefits to the health and stability of these systems.”
The research team conducted large-scale surveys across 13 tidal (潮汐的) streams, as well as small-scale field experiments at five locations around the river mouth over a six-year period. Otters were not included in some lest sites but allowed to be used in others, using a caging system designed by Angelini.
“And all these years later, we now see these amazing results. It’s an inspiring story about the benefits of conservation and persistent, long-term research,” Angelini said.

10 . Al Larson, also known as “The Bluebird Man”, first began his labor of love after he read an article that described how building birdhouses could help to control their falling populations. After seeing a bluebird going in and out of a dead tree in his yard, Larson became inspired to start setting up little boxes that could serve as nests (鸟窝) for bluebirds.
What started as a hobby in his retirement turned into a full-time effort — and after almost forty years of devotion, he has recorded over 30,000 bluebirds, thanks to the 350 birdhouses that he has built across southwest Idaho. He often travels over 5,000 miles to check on all of his boxes during the summer nesting season.
Since bluebirds live in dead or nearly-dead trees, their population began to drop after the invention of the electric chainsaw (链锯) in the early 1900s, which made it easier for homeowners to remove their dead trees. In addition to having their habitats destroyed, the use of pesticides (杀虫剂) caused an uncertain future for the bluebirds of Idaho. But the efforts of Larson have shown us that if we take a moment to understand the needs of a species, we’ll find a way to deal with the problem. Though he is nearing the age of 97, Larson shows no signs of slowing down. Also, his inspiring story has been turned into a documentary Bluebird Man.
“Al is a living example of how much one person can achieve when they set their mind on a task. But he’s also an example of the benefits that a project like this can have for people,” filmmaker Matthew Podolsky said. “Bluebirds have given meaning to Al’s life, and they are truly the secret to his long life.”
