Many animals have disappeared during the long history of the earth. Finless Porpoise (江豚) is one of these endangered{#blank#}1{#/blank#}that are dying out. As a student, I am asking you to pay attention{#blank#}2{#/blank#}the situation of Finless Porpoises. Finless porpoises in the Yangtze River are in danger of becoming extinct because they are seriously{#blank#}3{#/blank#}(affect) by human activities. To our disappointment, only about 1,000 are still living at present. We sincerely hope that WWF can play a role in{#blank#}4{#/blank#}(protect) this endangered species. Firstly, we find{#blank#}5{#/blank#}important to get sponsorship(赞助). If the government pays the farmers, they will allow tourists hunt only{#blank#}6{#/blank#}certain number of animals. But more importantly, we need information from experts in WWF to help us better understand the animal. In that case, we can take{#blank#}7{#/blank#}(good) care of them than before. And prizes will be given to the organizations{#blank#}8{#/blank#}can protect them well. What's more, more workers should{#blank#}9{#/blank#}(employ) to help us{#blank#}10{#/blank#}the task is challenging, we are confident that we will succeed sooner or later.

    When digging outside the city walls, researchers {#blank#}1{#/blank#} (discover) thirty to forty bodies lying one on top of another. They had been murdered.

    The men dug with great care, trying not to disturb the {#blank#}2{#/blank#}(evident) of what had happened. Everyone was curious {#blank#}3{#/blank#}why all these people had been killed at the same time. Was it just {#blank#}4{#/blank#} coincidence?

    Deep in the ground below the bodies, they found a tomb {#blank#}5{#/blank#} was made of stone. It contained many valuable things, {#blank#}6{#/blank#} (include) much gold and many jewels. Inside it lay the body of a man that was {#blank#}7{#/blank#} (good) preserved. It was clear that the man had been a king, {#blank#}8{#/blank#} explained why the other bodies were there. The workers who had built the tomb were killed shortly after the king {#blank#}9{#/blank#} (die). That was because they wanted to keep the tomb a secret, and to make {#blank#}10{#/blank#} (they) companions for him in death.

    Clara Hale was born on April 1, 1905 in North Carolina. In 1932, Clara faced the saddest thing in her life. Her husband died,{#blank#}1{#/blank#} (leave) her with her two children. To support her children, she {#blank#}2{#/blank#} (get) a job as a babysitter(临时保姆)for children with mothers too busy{#blank#}3{#/blank#} (look) after their own children. During the next 25 years, she was a foster mother(养母)to over 40 children.

    As more and more {#blank#}4{#/blank#} (problem) of drug abuse(滥用毒品)came up, more and more people would come to her door, holding a child, usually because the child's mother took drugs and either couldn't {#blank#}5{#/blank#} wouldn't care for the child. Within six months, she had 22 babies in a five-room apartment. As {#blank#}6{#/blank#}matter of fact, her apartment was packed, but she never said no to a child who no one wanted.

    In 1985, Clara founded the organization {#blank#}7{#/blank#} (call) the Hale House Center. It was an organization for children {#blank#}8{#/blank#} mothers took drugs. At the Hale House Center, there would be about 100 children there a week.

    Clara was a loving,{#blank#}9{#/blank#}(self) mother to over 800 children in her life. She devoted her whole life {#blank#}10{#/blank#} these unwanted children. She died on December 18, 1992 with a feeling in her heart that she had changed people's lives.

How do you kill your time when you go to work? Most of us stare at our cell phones, and refuse to make eye contact with others. We just read, chat with others online or play games online. Or maybe we're using the time between stops to do our make-up, catch up on emails, or read a few chapters of a book. However, Dina Alfasi takes a very different approach.

Each day she has to travel hours on buses and trains to get to her engineering job at a hospital in Israel. Rather than look at her cell phone in silence, she uses one very special way to have connection with strangers. It is portraits of the people she meets on public transport every day that she is taking. The photographs catch those quiet and personal moments of people readying themselves for the day ahead. Some people lean their heads against the window and go to sleep, some stare into space and have a daydream, and others sit quietly to read their documents or books. Each picture captures one tiny moment in people's lives, ripe with potential for your imagination. It is wonderful for her to look at someone's commute(上下班) and make up an entire story about the rest of their daily existence, from the father travelling with a baby to the woman welcoming a change.

"What inspires me very much are the little moments that happen every day," Dina told My Modern Met. "My work is to tell stories through a single portrait, and it proves that all you need is just to look around and find those magic moments."

The Aviation Industry Corporation of China (AVIC), China's leading aircraft maker, created the country's first fully solar-powered drone (无人机). The large drone, Qimingxing 50, took off at 5:50 pm on September 3rd, 2022, from an airport in Yulin of Shaanxi Province and stayed in the air for 26 minutes before landing on the same runway. AVIC said that all systems of the unmanned plane functioned well on its first flight.

Powered by six electric motors with solar batteries, the drone is designed to conduct long-time operations in near space. Near space is that part of Earth's atmosphere at altitudes of 20 to 100 kilometers. It is above the top altitudes of commercial airliners but below orbiting satellites.

Qimingxing 50, also called "quasi-satellite", features high operational efficiency and eco-friendliness and will be tasked with high-altitude reconnaissance (侦察), forestry fire monitoring, atmospheric environmental inspection, aerial mapping, communication signal relay and other operations.

"Thanks to its capability to conduct very long endurance flights in near space, the drone can essentially become a substitute for satellites," a Chinese aerospace expert said. Satellite services are not always available due to the limited number of satellites and relatively fixed schedules of overhead passes. In time-sensitive missions, near-space drones can offset these disadvantages, the expert said, noting that satellite services could also be damaged in wartime, so near-space drones could replace them in this occasion.

The successful first flight of the Qimingxing-50 lays a solid foundation for the development of key technologies in the country's new energy field, the composite (复合的) material field, which will enhance China's ability to perform tasks in near space and over far oceans. AVIC will seize the opportunity to increase investment and speed up the development of large solar-powered unmanned aircraft.
