T hree Chinese astronauts came back to the Earth. They shared stories about their space station life. One experiment (实验) was feeding fish in weightlessness (失重).

“The zebrafish were our friends!” said astronaut Li Guangsu. On the space station, they kept four fish and green plants in a closed tank (水箱). At first, the fish didn’t move—they floated (浮) in water for days. “We thought they need time to adapt (适应),” Li said.

After a week, the fish became active! They swam upside down, turned, and circled. The astronauts fed them and took water samples. “Their movements looked like our first days in space—we also floated!” Li laughed.
The fish lived for 43 days—setting a record! *Chinese scientists studied how they adapted to weightlessness. The closed tank let astronauts watch quietly. No feeding mistakes and no water leaks (渗漏) happened.
“We did many experiments: fire, water, plants, and fish,” said the head astronaut Ye Guangfu. “These studies help us understand life in space.”
For the astronauts, the fish meant more than science. “They made the space station feel alive,” Li said. “We even named them secretly… but we can’t tell you the names!”

答案： 1.A 行文方式题。由第一段第一句 Three Chinese astronauts came back to the Earth. 可知，作者以介绍事实作为本文的开头。
2.B 推理判断题。由第二段的 At first, the fish didn't move—they floated in water for days. 可知，一开始，鱼一动不动——它们在水中漂浮了好几天。故推断 B 项符合语境。
3.A 细节理解题。由第四段的 The fish lived for 43 days—setting a record! 可推知，作者谈及 43 天是为了强调这个时间创造了纪录。
4.B 推理判断题。由第二段的 The zebrafish were our friends! 和最后一段的 We even named them secretly... 可推知，中国航天员把斑马鱼当成自己的朋友。
5.D 主旨大意题。本文讲述了中国航天员返航后披露空间站斑马鱼失重实验的相关情况。由此可知，D 项最适合作标题。
