If you grew up watching the kid’s television channel Nickelodeon, you will probably understand that there is nothing greater than enjoying its special bright green slime (水晶泥). The week of May 11, astronauts aboard the International Space Station (ISS) joined the slime.
Nickelodeon sent two kilos of its green slime into space in the summer of 2019. The Slime in Space project’s idea was to create an educational trip for teachers to use in class. The green slime was also used to guide astronauts through a series of experiments that were designed to learn more about how slime acts in microgravity.
Researchers from Portland State University (PSU) were excited to design the experiments for the project. Mark Weislogel and his partner designed eight shows for NASA astronauts and European Space Agency astronauts aboard to perform.
If you’re wondering what we could hope to learn from sending slime into space, the answer lies in its very name. Slime is slimy. This is because it is a liquid that is thicker than liquids like water. This makes slime act in unexpected ways in the microgravity of the ISS. Improving our understanding of how thicker liquids act in space may help us improve the design of systems that something were designed with Earth’s gravity in mind.
“Interestingly, we consider liquid on Earth as that takes the shape of its container, ” Koch tells CNN. “Water just turns into a ball in microgravity, so we’ve had to have a new understanding of different kinds of matter in space. This experiment shows how microgravity can help us understand things on Earth, especially the things we take for granted. ”
【文章大意】本文是一篇说明文。文章主要说明了宇航员把水晶泥带入太空进行实验以及这个实验的重要意义。
21. In Paragraph 1, Nickelodeon is mentioned .
A. to introduce the topic
B. to attract the kids
C. to make advertisements
D. to share a TV show
【解析】选A。推理判断题。根据下文的内容可知, 文章主要介绍了宇航员把水晶泥带入太空进行实验, 这对于我们研究地球物质有很大意义, 可推断第一段提到Nickelodeon的水晶泥是为了引出话题。故选A。
22. Why are the experiments with slime designed in space?
A. Because they get students interested in space.
B. Because slime takes the shape of its container.
C. Because slime is popular with kids in the TV show.
D. Because they help us understand how slime acts in space.
【解析】选D。细节理解题。由第二段“The green slime was also used to guide astronauts through a series of experiments that were designed to learn more about how slime acts in microgravity. ”可知, 在太空进行水晶泥实验是为了更好地了解水晶泥在微重力下的表现。故选D。
23. Which of the following can be the best title of the text?
A. Microgravity makes a difference to matters.
B. Astronauts join the slime in space for science.
