2 . Constantin de Slizewicz has been anxious to come back to China since early 2020.For the past decade, the Frenchman has been running a luxurious （豪华的）camping business in Shangri-La in the southwest of China's Yunnan Province. But in December 2019, he went back to France for a vacation. He usually goes back to France and stays there for two to three months, since there is little business due to the weather.

Following the outbreak of COVID-19, however, he found it difficult to return. Fortunately, his business partner Guillaume de Penfentenyo was able to get a flight to China at the end of February.

Previously, most of his customers were international guests from outside the country who were drawn to the beautiful landscape and scenery in Shangri-La. Despite the pandemic（疫情）and even in his absence, Slizewicz's company managed to attract new tourists, who were unable to travel abroad under the circumstances and discovered the joy of camping. "It makes sure of our operation," he says happily.

Last year, his team offered summer camps in Shangri-La for Chinese students who couldn't travel abroad. In autumn, many domestic travelers also signed up for his company's organized adventures deep into the wilderness.

Slizewicz first visited China in 1996 when he engaged in a three-month internship（实习期）. He was impressed by the Chinese people around him and was attracted by places like Guizhou and Yunnan provinces, which were well-matched to his interest in camping-a passion he has had since childhood. "I met people in the mountains, singing and herding their yaks（牦牛）. That makes the mountains feel special and alive,” he says.

3 . Columbia high school girls’ soccer team had lost every game in the season until a new ______stepped in two years ago.

Stuart Henley, a former soccer player and now a truck driver, ______the team and started training hard in February 2020. He ______the progress of the girls to team-building activities to help them bond on and off the field. He focused on the basics of football like passing, ______, and movement to try and bring the girls up to a good standard. His ______: coaches could give them guidelines, but girls ______what they felt they needed to work on.

Obviously, the girls were onto something big in the new season. They ______the skills they had learned and teamwork into their ______, which led them to an ______run of eight games, until they were sadly beaten 3-2 by Wyrley Pumas Team. Although this means they have been _____ the league title, the team have still exceeded (超出) expectation by earning the ______to the county’s top division.

“Whatever brings you down will ______make you stronger, especially for girls.” Captain Chelsea said, “Stuart has really ______our girls the philosophy of playing soccer. We’re going into next season full of confidence and ready to compete against tougher ______, but for now we’re still very much enjoying our ______.”

5 . In 2010, Barack Obama was to pay a visit to Mumbai’s Gandhi Museum, where palm(棕榈)trees full of me dotted the grounds. The president knew me well-coconuts (椰子)are a part of life in Indonesia, where he spent his boyhood. Before his visit, Indian authorities, however, removed every last sign of me around the museum. They were afraid the president of the United States would be taken out by one of me falling on his head.

Let’s get this out of the way: My reputation as the “killer fruit” of countless innocents was then and still is a misbelief. A repeatedly misinterpreted 1984 study overstated the number of deaths I caused by hitting people on the head, and the word spread. Today, the only things about me “to die for” are the sometimes too-delicious foods you humans make with me, such as cookies and pies. A decade ago, health experts briefly gave me a halo because some of my fats may raise beneficial cholesterol (胆固醇). But ask a heart doctor today and they’ll tell you that coconut oil will raise your bad cholesterol as much. Death by coconut, indeed!

People have other wrong ideas about me. But allow me to leave you with a sweet presidential tale. A World War II boat commanded by one John F.Kennedy was destroyed in 1943 by a Japanese warship. Kennedy and his surviving crew were stuck on an island. They were suffering from hunger, thirst and injuries when they met two friendly native coast-watchers. Kennedy scratched a message into a coconut shell: “NAURO ISL...COMMANDER...11 ALIVE...NEED SMALL BOAT...KENNEDY.”

The coast-watchers delivered this successfully and all the crew were saved. Years later, the coconut shell was given to the newly elected president. It sat on his office desk throughout his presidency and now is a center-piece of the John F.Kennedy Library in Boston-as the proof that we coconuts don’t take lives, we save them.

7 . It is indeed true that age is not a barrier (障碍) to learning. Priscilla Sitienei, a 90-year-old woman, has ________ it and is an inspiration to all of us who tend to give up so ________.

Priscilla, as a young girl, did not have the ________ to read and write. What she could not do then did not stop her from dreaming and ________ making those dreams come true. She has ________ Leaders Vision Preparatory School in her village in Kenya for the past five years. What is even more ________ is that she goes to school with her great-grandchildren! She says that she has big________ and that she'd like to be able to ________ the Bible (圣经). She also wants to ________ children to receive schooling and to follow their ________.

Her day at school is the same as any other student's. She wears her ________ to school and attends English, Maths, Drama, Singing, Physical Education, and Dance classes. Above that, she lives in one of the school dormitories, where she________ the room with her great-great-grandchild. All pupils ________ her and want to play with her. She sets an example to those who have ________ and think they are too old to get ________. She says, "Well, I am at school, and so should you!"

9 . Famous Israeli gastronome (美食家) Michal Ansky is a professional taster and a Master Chef judge. So when she was invited to the world’s first public blind taste test setting lab-grown chicken into competition against a conventionally raised product, she was confident that she would be able to tell the difference.

Surrounded by cameras at a restaurant bar, she tasted from two dishes, labeled A and B. A team of lawyers looked on, tasked with making sure that the tasting truly was blind. Even the chef who sautéed (嫩煎) the meat in sunflower oil—no salt, no seasonings—didn’t know which was which. Both were flavorless, Ansky noted, but she would bet her reputation that sample A was the real thing. It had a richer, more “chickeny” taste.

The tasting was hosted by a meat-tech startup SuperMeat at its in-house restaurant, The Chicken. Ever since 2013, when the first lab-grown hamburger was presented to the public with a $330,000 price tag, alternative-meat companies have been inching closer to a product that is just as tasty and nearly as affordable as the real thing, but without the climate impacts. One new study found high-income countries could cut agricultural emissions (排放物) by almost two-thirds by moving away from animal-based foods.

But one question remains: Would consumers be able to tell the difference? SuperMeat decided to put its product to the test without the deep frying and sauces that are usually used to mask a lack of flavor. Sample B had less flavor, so Ansky reasoned that it had to be the one grown in a lab. She was so convinced of her decision that when SuperMeat founder Ido Savir announced that it was in fact A that was lab-grown, she corrected him. “No,” she said. “A is the real chicken.”

A day later, I spoke to Ansky about the tasting. “It’s one of the only times in my life that I’m really happy that I was wrong,” she admitted.

10 . As of 2020, the world's biggest lithium-ion (锂离子) battery is hooked up to the Southern California power grid and can provide 250 million watts of power, or enough to power about 250,000 homes. But it's actually not the biggest battery in the world: these lakes are.

Wait - how can a pair of lakes be a battery? To answer that question, it helps to define a battery: it's simply something that stores energy and releases it on demand. The lithium-ion batteries that power our phones, laptops, and cars are just one type. They store energy in lithium ions.

How do the two lakes store and release energy? First, one is 300 meters higher than the other. Electricity power pumps that move billions of liters of water from the lower lake to the higher one. This stores the energy by giving the water extra gravitational potential energy. Then, when there's high demand for electricity, valves (阀门) open, releasing the stored energy by letting water flow downhill to power 6 giant turbines that can generate 3 billion watts of power for 10 hours.

Unfortunately, neither of the giant batteries we've talked about so far is big enough to power multiple cities. The two lakes setup requires specific geography, takes up a lot of land, and has high upfront costs to build. The giant lithium-ion battery in California can power about 250,000 homes, yes, but only for an hour. Lithium-ion batteries also require certain heavy metals to make. These resources are limited, and mining them causes environmental damage. Inventors all over the world are rising to the challenge of making batteries that can meet our needs - many of them even weirder than the two lakes.
