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.

D、Its environmental benefits(3)、What does the underlined word "offset" in paragraph 4 probably mean?A、Detect. B、Expose. C、Analyze. D、Remove.(4)、What will AVIC do in the future?A、Increase investment in the new energy industry. B、Accelerate the development of large solar drones. C、Create a new composite material to manufacture aircraft. D、Make Qimingxing-50 conduct long-time tasks over far seas. -

Pleasanton Partnerships in Education Foundation (PPIE) was started in 1987 to raise money by organizing running events for local schools. Based in Pleasanton, California, a suburb of San Francisco, the non-profit organization recently hosted a family-focused fitness event for the community. "Our event helps to bring the community together," said Mindy Louie, events and outreach manager for PPIE. "We have more than 3,000 participants, hard-working volunteers and viewers."
This year's fitness event took place on April 30 at the Alameda County Fairgrounds. It featured races of two miles, five kilometers and ten kilometers. A new Kids Challenge consisted of a quarter-mile run to encourage younger children to participate. When asked to describe the run, 11-year-old Jeremy Louie said, "Fun, exciting and enjoyable." Jeremy added that he was happy to help support his school.
PPIE supports all 15 schools in the Pleasanton Unified School District, which include more than 14, 500 students and 800 teachers and staff. The nonprofit organization tries to fund programs affected by budget cuts, while encouraging fitness and athleticism. To date, the PPIE has raised over $1 million for the school district.
A local runners' group called the BURN Youth Development (B. Y. D.) participated in the fundraising. The B.Y.D. has since grown to more than 100 youth members, 30 of whom ran in April's PPIE event. Jerry Wu, the group's founder and lead coach, explained that the B.Y.D. was born to keep kids running. "Watching them running strongly and happily makes me smile every time," Jerry said.
Jerry encourages teamwork and teaches the students valuable running techniques. As a B.Y.D. member, Ollie Gu, an eighth grader, was one of the top finishers in the ten-kilometer run. He completed the race in 40 minutes and 46 seconds and won first place in the 12-to-15 year-old age group. "The race was extremely rewarding," Ollie said. "I'm looking forward to it next year."
(1)、Which race was recently created?A、A ten-kilometer run. B、A quarter-mile run. C、A five-kilometer run. D、A two-mile run.(2)、Why does the author list some numbers in paragraph 3?A、To stress the great influence of PPIE. B、To show a small budget for education. C、To introduce the school district in brief. D、To advertise the organization's programs.(3)、What did both Jerry and Ollie want to convey?A、Their duties as athletes. B、Their feelings as coaches. C、Their recognition of theB.Y. D、D. Their anticipation of the next run.(4)、What is the text mainly about?A、Sports volunteers. B、Young sportsmen. C、Running with teachers. D、Racing for education. -
