On Friday, Chiamaka's class had a video call with a space station. The room was very quiet. An astronaut smiled on the big screen. Behind her, bags and tools floated in the air.
星期五，奇亚马卡的班级和空间站进行了一次视频通话。教室里非常安静。一位宇航员在大屏幕上微笑着，她身后，包裹和工具在空中漂浮。
The astronaut answered questions about food, exercise, and the view of Earth. Each student stood up, asked a question, and sat down. Chiamaka was the last in the line. Her question was ready on a small paper. Her hands were cold. She read the question again and again.
宇航员回答了关于食物、锻炼和地球景色的问题。每个学生站起来，提一个问题，再坐下。奇亚马卡排在最后。她的问题写在一张小纸条上，早就准备好了。她的手冰凉。她一遍又一遍地读着那个问题。
"Chiamaka, you are next," her teacher said.
“奇亚马卡，轮到你了，”老师说。
She stood up. At that moment, the screen froze. The astronaut's face stopped in the middle of a smile. A small circle turned on the screen.
她站了起来。就在这时，屏幕卡住了。宇航员的脸停在微笑到一半的样子，屏幕上转起了一个小圆圈。
"The connection is gone," the teacher said. Everyone sighed.
“信号断了，”老师说。大家都叹了口气。
Chiamaka sat down. She held her paper and waited. Five minutes passed. Then ten. The teacher looked at the clock.
奇亚马卡坐了下来，拿着她的纸条等着。五分钟过去了，又过了十分钟。老师看了看钟。
Then the screen came back. "I'm sorry," the astronaut said. "The signal is weak. I only have one minute."
然后屏幕恢复了。“对不起，”宇航员说，“信号很弱，我只有一分钟时间。”
Chiamaka jumped up. "How do you sleep in space?" she asked.
奇亚马卡一下子跳起来。“你在太空里怎么睡觉？”她问。
The astronaut laughed. "I sleep in a bag on the wall. If I do not tie it, I float all night!"
宇航员笑了。“我睡在墙上的一个睡袋里。要是不把它系好，我整晚都会飘起来！”
All the students laughed. "Thank you!" Chiamaka said.
所有的学生都笑了。“谢谢你！”奇亚马卡说。
The screen went dark. Chiamaka opened her notebook and wrote the answer: "Sleep bag on the wall. Do not float."
屏幕暗了下来。奇亚马卡翻开笔记本，写下了答案：“睡袋挂墙上。不要飘。”
