新素材·太空烤箱 China’s Tiangong Space Station welcomed a new thing—a special hot-air oven! Astronauts from the Shenzhou-21 and Shenzhou-20 missions used this device successfully for the first time in space. This is an important step to improve Chinese astronauts’ dining experience in orbit. They can enjoy tasty baked food even hundreds of kilometers away from Earth.
Before this new invention, most space food was cooked beforehand and ready to eat. There were not many choices for taste and texture. The new oven has made the space menu much more varied(多种多样的). Astronauts have already tried baking popular dishes like “Orleans-style” chicken wings and black pepper beef steak. A video from the space station showed them carefully placing the chicken wings into the oven. After 28 minutes of exact heating, the delicious and soft chicken wings were done. The astronauts liked them very much.
However, baking in space brings special challenges. Liu Weibo, an expert in space life support technology, explained that the main difficulties are dealing with smoke and oil fumes. These could make the space station’s air dirty. The specially designed oven uses new technologies to clean smoke and collect oil. This makes sure the air in the cabin(座舱) stays clean. Besides, the oven is made to be strong and long-lasting. It can work well at least 500 times to meet the needs of long space missions.
The new oven is part of China’s ongoing work to make astronauts’ living conditions better in space. Now, the space station has more than 190 kinds of food. The menu is updated every 10 days to give different and healthy food choices. Apart from the oven, the “space garden” on the station is also growing well. Astronauts have successfully grown fresh vegetables like lettuce and cherry tomatoes. These add more fresh food to their meals.
“When astronauts stay in a small space for months, eating self-baked food not only makes their taste buds happy but also brings great mental comfort,” Liu Weibo said. It turns out that a nice and delicious meal is always the best comfort, even in a huge space far from Earth.
1. Why was the hot-air oven introduced to the Tiangong Space Station?
A. To improve the taste and variety of space food.
B. To reduce the weight of food carried from Earth.
C. To test new cooking methods for longer space missions.
D. To help astronauts cook vegetables from the space garden.
2. What does China’s effort to improve space food show?
A. Chinese astronauts can enjoy any food they want in space.
B. The space garden is the main source of food for astronauts.
C. China is developing modern space life support technologies.
D. Enough food is the most important thing in our space station.
3. Which of the following shows the proper use of the special hot-air oven’s design idea?
A. Baking cookies in a home kitchen with windows open.
B. Using a smoke-free small oven in a closed training cabin.
C. Cooking vegetable meat soup for a big family at a picnic.
D. Heating cold rice for many students in a school dining hall.
4. What is the main idea of the passage?
A. The growth of fresh vegetables in the space garden.
B. The variety of food provided on China’s space station.
C. Difficult challenges of space baking and our solutions.
D. A special hot-air oven on Tiangong and its importance.
