2026年期末直通车八年级英语下册外研版第75页答案
B
After staying at the International Space Station(ISS,国际空间站) for nine months, American astronauts Suni Williams and Barry Wilmore finally returned to Earth. The Space X Dragon spacecraft(航天器) took them home.
Williams and Wilmore arrived on the ISS in June 2024 for a week-long trip. However, because of problems with their spacecraft, the Boeing Starliner, they had to wait to return to Earth.
Life for the two astronauts in space was busy. They spent over 900 hours on science studies and did experiments that will help with future medical development. Williams also finished two spacewalks, bringing her total to nine—a new record for women astronauts.
To keep their bodies from getting too weak in the zero-gravity(零重力) environment, the astronauts exercised for at least two hours a day. They used special tools to copy the feeling of working out on Earth.
“We’re doing pretty well, actually. We’ve got food, we’ve got clothes. Both of us have trained to live and work on the International Space Station, and I think we’ve made the most of it,” said Williams.
Even with their efforts, they still became weaker. What’s more, Space travellers experience 100 times more radiation(辐射) than people on Earth, which may increase their risk of illness in the future.
The two astronauts not only worked in space but also did other things. For example, they wore Christmas hats and made video calls with their loved ones to celebrate the festival.
