They have a wide range of origins, such as the seasons of the year, religions and important events. Festivals can① also be held to honour famous people. Some festivals are held to honour the dead or to satisfy the ancestors. Most ancient festivals would② celebrate the end of cold weather, planting in spring and harvest in autumn. Most restaurants ought to③ be full of people during these festivals. For the Qingming Festival, people should④ go to sweep graves in memory of their ancestors. And if you study festivals carefully, you may⑤ be surprised to find that different cultures actually have a lot in common after all.

But they can't be experts in everything. That's why robots are tested to see if they can fill in some of the gaps. A robot MIRA took an important step in that direction. Scientists succeeded in testing the robot's ability to perform operations while on the International Space Station (ISS). And what's more, they controlled the robot remotely from Earth. Robots have long been used in surgery, but MIRA is the first miniature version of robotic-assisted surgery technology in development. The researchers said it's about 1,000 times lighter than previous technologies, making it ideal for space travel where every pound matters. The goal of the experiment was to see if and how MIRA's surgical capabilities would be affected by zero gravity. It attempted to perform a series of surgical tasks on simulated human tissue while aboard the ISS, remotely controlled by six researchers in Lincoln, Nebraska. The robot performed a dissection(解剖) task common in surgeries, using its left hand to create tension in the tissue and its right to dissect the tissue with scissors. Researchers reported that the robot was able to successfully complete the task. As to the question of how zero gravity affects the robot's surgical skills, they said it would take a few weeks or months before results were sent back to Earth. One goal of the research is to develop technology that could one day allow doctors to perform surgeries on astronauts remotely from Earth. It could also have a big impact on Earth, helping those who don't have access to a surgeon get the help they need. 语篇解读：本文是一篇说明文。文章介绍了一种机器人MIRA在空间中完成对模拟人体的手术，这个机器人有望填补人类宇航员所无法做的一些空白。 解析：推理判断题。根据第一段的内容可知，宇航员为太空旅行中可能出现的问题做了很多准备，但他们不可能精通所有事情，这就是测试机器人是否能填补一些空白的原因，其目的是导入文章关于机器人MIRA的话题。 √ 1．What is the function of paragraph 1?
