An experiment at the Tiangong space station can provide the answer. Chinese astronauts have successfully grown rice seedlings (幼苗), which may show us how astronauts can cultivate food to support long-term space flights. “The rice seedlings are growing very well, ” Zheng Huiqiong, a scientist at the Center for Excellence in Molecular Plant Sciences of the Chinese Academy of Sciences, told China Daily. Since the rice experiment began on July 29, 2022, the seedlings of the tall shoot rice variety (高杆水稻品种) have reached a height of about 30 centimeters. Plus, the seedlings of the dwarf rice variety (矮秆水稻 品种) have grown to around 5 centimeters. While there have been other rice experiments in space, the one being conducted on Tiangong is the first of its kind. It aims to produce the complete life cycle of the plant, which begins with a seed and ends with a grown plant producing new seeds. The astronauts will keep studying the plants. If the experiment is successful, they will collect the newly produced seeds and bring them back to Earth for further studies, Zheng added. Since the 1980s, China has been taking the seeds of crops to space. But growing rice in orbit (轨道) is a different challenge due to the hard conditions in space. Micro-gravity, no air and high-energy cosmic rays (宇宙射线) may make it hard for the plants to grow. Rice has been a staple food for astronauts for a long time. US astronauts on the Apollo 11 mission - the first humans to land on the moon in July 1969-ate freeze-dried chicken and rice during their trip to space. If such an experiment goes well, astronauts will be able to grow their food in orbit, reducing how much food has to be taken on space flights. 1. What does “cultivate” in Paragraph 1 probably mean?

B 根据上文 “How do plants grow in space?” 以及 “Chinese astronauts have successfully grown rice seedlings” 可知，这里说的是宇航员如何种植食物来支持长期的太空飞行，“cultivate” 意思是 “种植；培育”，与 “grow” 意思相近，故选 B。 2. D 第二段中提到高杆水稻品种的幼苗已经长到大约 30 厘米高，矮秆水稻品种的幼苗已经长到大约 5 厘米高，结合上文 “The rice seedlings are growing very well” 可知，描述水稻品种的高度是为了表明水稻实验进展顺利，故选 D。 3. C 第五段提到 “Since the 1980s, China has been taking the seeds of crops to space. But growing rice in orbit (轨道) is a different challenge due to the hard conditions in space. Micro-gravity, no air and high-energy cosmic rays (宇宙射线) may make it hard for the plants to grow.”，主要说明了在太空中种植水稻困难的原因，即微重力、没有空气和高能宇宙射线可能使植物难以生长，故选 C。 4. B 最后两段中提到 “Rice has been a staple food for astronauts for a long time.” 以及 “If such an experiment goes well, astronauts will be able to grow their food in orbit, reducing how much food has to be taken on space flights.”，主要讲述了水稻实验的重要性，包括水稻一直是宇航员的主食，以及实验成功后宇航员能在轨道上种植食物，减少太空飞行中携带的食物量，故选 B。 5. B 文章主要介绍了中国宇航员在天宫空间站进行的水稻种植实验，包括实验的进展、目的、面临的挑战以及重要性等，属于科学领域的内容，所以可能在科学杂志上读到这篇文章，故选 B。 学科网（北京）股份有限公司 $$
