1 . When 15-year-old Amy began working on her family’s farm in the early morning, she was greeted by a rare sight - an extremely large eagle with a broken leg. “He was ________ and trying to fly, which panicked (惊慌) me a little because he was the ________ of my sheepdog,” she said. “I’m seriously not a bird person. I can ________ cows that weigh nearly a ton but won’t go near a bird, I won’t even go near chickens.”

Seeing the bird ________ in trouble, Amy quickly called for help. ________ her own fear of birds, she was sad to see a local eagle hurt. “I rang my mum immediately. I couldn’t ________ him there. I felt really bad for him because he was all wet and cold,” Amy said.

Since the eagle was living in a nest on Amy’s farm, it has ________ the teenager. But ________ the rescuers from Wildlife Rescue South Coast arrived it gathered all of his ________ to give them a good chase, alert (警惕的) to the new people. Rescuer Amara Mohan immediately noticed the eagle had broken his leg, and after three hours of struggling it was finally ________ and eventually taken to Sydney’s Small Animal Specialist Hospital for a (an) ________. A pin and plate were put in his left ________, a delicate operation on such a small bone.

Ms. Mohan said that after the operation, the eagle was ________ well at Raptor Recovery Australia. “It is really bright; it’s using his right leg and putting more ________ on it now,” Ms. Mohan said. Amy hopes all is going well and the eagle can be returned to her family’s farm. “I’ve done a lot of ________ things on the farm—saving the eagle is one of them.” She said.

2 . In the Beijing Winter Olympics, we were treated to incredible displays of athletic talents ascompetitors took to the snow and ice. As a popular sport at the Winter Olympics, ski jumping is oneof the best examples to showcase the “superhuman” power of athletes.

Ski jumpers soar into the air and appear to be almost flying in the sky. How do they achieve this? Physics call offer us an explanation of how they make it. It involves the use of the laws of aerodynamics(空气动力学)to fight against gravity and increase lift while reducing drag.

To understand how ski jumping works, we need to consider three elements: gravity, lift and drag. Gravity is the force that pulls us towards an object. Lift occurs when an object is moving through the air—as its surface comes into contact with air particles(微粒), the particles are pushed down and away from the object, allowing it to move up. At the same time, this interaction createsdrag, and slows down an object’s movement.

While there is nothing that the skiers can do about gravity, they can twist their bodies into positions to allow them to achieve greater lift and avoid as much drag as possible. According to the Smithsonian Magazine, “To do this, athletes try their best to make their skis and body nearly parallel to the ground and place their skis in a V-shape just outside the form of the body. This position increases the surface area that produces lift and puts them in the ideal angle that will also maximize(最大化)lift.”

Because of how the sport works, athletes’ equipment is strictly controlled according to weight and height in order to avoid any unfair advantages. This means suits must be tight in order to ensure athletes cannot use them as a way to gain more lift. For athletes, minor day-to-day waterweight changes as little as 300 grams. It can mean that suits will not be tight enough according to their body mass indexes(体重指数).

3 . It is common to see most live streamers sitting in front of a desk in a well-decorated room. But Zeng Qinghuan, a 30-year old from Xinhua County in Loudi, Hunan, has turned her whole village into a live streaming set. Her goal is to use e-commerce to help her people live a better life.

Known as “Xiangmei Xinbao” on Douyin, Zeng now has more than 3 million followers. One of her videos about traditional ways of planting and harvesting rice has attracted more than 300,000 followers.

Zeng used to study fashion design and has worked in some big cities before. In 2019 she returned to her village to care for her sick grandmother. She then found that she could build a career there—by being a live streamer with the help of her cousin.

At the beginning, she didn’t make any money. Zeng’s parents didn’t give her any support until she could stand on her own feet and help people sell their products. She has now sold local agricultural products worth tens of millions of yuan, like fermented tofu, preserved pork and dried sweet potatoes.

“I’m a daughter of the great mountains. I can also be a contributor to rural development in these new times,” she said.

Rural revitalization (振兴) is a key part of China’s 14th Five-Year Plan (2021-25). Zeng hopes her experience can encourage more young people to return to their rural hometowns and start their own businesses. In 2021,after she became a deputy (代表) of the Loudi Municipal People’s Congress, she put forward a proposal to ensure that “each village has one product and one live streaming host of its own”. She plans to help cultivate 100 social media influencers from her county within three years, and two villages have taken part in the project, “I believe that the rural areas will become a big stage, and being a farmer will be seen as a respectable job too,” said Zeng.

Chinese scientist Yuan Longping, globally known for developing the first hybrid rice strain in 1973 that relieved countless people     1     hunger, passed away on Saturday at the age of 91.

The scientist spent over five decades researching and improving hybrid rice,     2     has reached its third generation, feeding     3     (near) one-fifth of the world’s population with less than 9 percent of the world’s total land. In China, the annual planting area of hybrid rice has topped 16 million hectares, or 57 percent of     4    total planting area of rice. Its growth area overseas has reached 8 million hectares. His more recent achievements included developing     5     (variety) of seawater rice, or saline-alkali (盐碱) tolerant rice. His team planned to use the rice     6     (transform) 6.7 million hectares of saline-alkali land in China over the next eight to 10 years.

Yuan once said he had two dreams－to “enjoy the cool under the rice crops    7     (tall) than men” and that hybrid rice could be grown all over the world to help solve the global     8     (short) of food.

Yuan’s lifelong devotion to     9     (reduce) hunger has made him a national hero and household name in China. In 1999, an asteroid (小行星) discovered by the National Astronomical Observatories     10     (name) after Yuan. In 2019, he was awarded the Medal of the Republic, China’s highest state honor.
