(B)
China’s Tiangong space station has successfully sent back special samples(样本) from space. Astronauts worked hard to collect space samples with robotic arms in the space station. The samples are heavy—they weigh several kilograms. Hopefully, they will help scientists study what happens to different materials and human health because of gravity.
Life in space is different. Without the Earth’s gravity, astronauts don’t walk—they float! To stay healthy, they must do exercise for two hours every day. The Tiangong spacecraft circles our planet about 400 kilometres above the Earth’s surface. From there, astronauts have an amazing view of our beautiful planet and take many photos of it.
Scientists have an important question: Why do astronauts get weaker in space? This research may help both future space travellers and sick people on Earth.
China’s space programme is a great success. The Tiangong space station has done many important experiments so far. Maybe you will have the chance to visit a space station when you grow up!
46. What can we learn about the samples in the first paragraph?
A. It is hard to collect them in space.
B. They are too heavy to bring back.
C. Scientists study them hard in space.
D. They will help astronauts protect the space.
47. Why do scientists want to study the samples from space?
A. To learn why the astronauts float in space.
B. To see how heavy the samples are in space.
C. To test the Tiangong space station’s equipment.
D. To know how gravity changes materials and health.
48. What may happen in the future according to the passage?
A. People on Earth will send more samples to space.
B. More students in China will become astronauts.
C. Students might travel to space stations one day.
D. The gravity will become stronger in space.
49. What can be a suitable title for the passage?
A. China’s great scientists
B. Tiangong’s great success
C. The importance of gravity
D. How to become an astronaut
50. In which part of a magazine can we read the text?
A. Health
B. Travel
C. Traffic
D. Science

解析
【分析】
本题为英语阅读理解题，包含细节理解、推理判断、主旨大意类题目。解题思路为：先通读原文把握核心内容，再针对每道题的题干关键词回原文定位对应信息，逐一比对选项与原文表述，排除无中生有、偷换概念等错误选项，选出正确答案。
46题定位第一段关于样本的描述，47题定位第一段末句，48题定位最后一段末句，49题需概括全文主旨，50题判断文章所属杂志板块。
【解析】
46. 细节理解题。根据第一段“Astronauts worked hard to collect space samples with robotic arms in the space station.”可知宇航员努力收集样本，说明收集样本有难度，对应A选项；B选项“太重带不回”与原文“they weigh several kilograms”不符；C选项“科学家在太空研究样本”原文未提及，原文是样本帮助科学家研究；D选项“帮助保护太空”无依据，故选A。
47. 细节理解题。根据第一段末句“Hopefully, they will help scientists study what happens to different materials and human health because of gravity.”可知研究样本是为了了解重力如何影响材料和健康，对应D选项；A选项“宇航员漂浮的原因”是第二段内容，与样本研究无关；B选项“看样本多重”不是目的；C选项“测试空间站设备”无依据，故选D。
48. 推理判断题。根据最后一段末句“Maybe you will have the chance to visit a space station when you grow up!”可知未来学生可能去空间站，对应C选项；A选项“地球人送更多样本”原文未提；B选项“更多学生成宇航员”无依据；D选项“太空重力变强”与原文不符，故选C。
49. 主旨大意题。全文围绕中国天宫空间站的成功及相关研究展开，对应B选项；A选项“伟大科学家”偏离主题；C选项“重力的重要性”仅为部分内容；D选项“如何成为宇航员”未提及，故选B。
50. 推理判断题。文章介绍天宫空间站的科学研究、太空生活等内容，属于科学范畴，对应D选项；A选项“健康”仅涉及部分内容；B选项“旅行”、C选项“交通”均不相关，故选D。
【答案】
