The following is an example of a technical reading comprehension and answer: [Chang'e-5's sample collection mission] The Chang'e-5 probe had a lot of innovation in the lunar sample mission. At 23:10 on December 3,2020, the Chang 'e-5 ascender ignited on the lunar surface. After the 3000 Newtons engine worked for 6 minutes, it successfully sent the ascender carrying lunar soil into the scheduled orbit around the moon, successfully achieving China's first extraterrestrial celestial body take-off. After ignition and take-off, the ascender went through three stages: vertical ascent, attitude adjustment, and orbital injection, entering the scheduled lunar orbit. After that, they would rendezvous and dock with the orbital return assembly that was waiting around the moon, transfer the lunar samples to the returnee, and wait for the appropriate lunar entry window to return to Earth. After the Chang'e-5 probe landed on the lunar surface, it carried out preparations such as unfolding the solar wings and unlocking the mechanism before entering the "digging" mode. The automatic sampling-task adopted the combination of surface drilling and multi-point sampling-mode. There were two modes: drilling with drilling tools and surface sampling-by-mechanical arm. These two modes were not carried out at the same time. First, the drilling mode was turned on. The drilling tool mainly obtained samples below the lunar surface. As of 4:53 on December 2, the Chang 'e-5 lander and ascender combination completed the lunar drilling, sample collection, and packaging. Then, the robotic arm surface acquisition device began to work, mainly to obtain lunar surface samples. As of 22:00 on December 2, after about 19 hours of lunar surface work, Chang'e-5 successfully completed the automatic lunar surface sample collection and stored the samples in the storage device carried by the ascender in a predetermined form. In order to ensure that the lunar samples remained vacuum sealed and unaffected by the external environment during their return to Earth, the probe sealed the samples on the lunar surface. The lander carried equipment such as drilling and collecting devices, surface collecting and collecting devices, surface collecting primary packaging devices, and sealing devices to complete the sample collection mission. The robotic arm was similar to a human hand, and there were two samplers like shovels on the wrist joint. The drilling tool could drill into the moon to drill the lunar soil core. They cooperated with each other to collect lunar soil samples and seal them. It had been more than 40 years since humans last took samples from the moon. The study of lunar soil not only involved the moon itself, but also included important information about the space materials and energy of the solar system. Sending samples such as lunar soil back to the ground laboratory for analysis and research would help to further understand the state of the moon, temperature, material content and other important information, and deepen the understanding of the formation and evolution of lunar soil, lunar crust and the moon. ** Question and Answer: ** 1. What was the method of the Chang'e-5 probe's automatic sample mission? The answer was to use a combination of watch and diamond and multi-point samplings. 2. What was the difference between the drilling mode and the surface extraction mode of Chang'e-5? Answer: The drilling mode was first activated, and the drilling tool was mainly used to obtain samples below the lunar surface. The surface extraction mode was then activated, and the robotic arm was mainly used to obtain samples on the lunar surface. 3. What equipment did the lander carry to complete the sample mission? The answer was: drilling sample device, surface sample device, surface primary sealing device, and sealing device. 4. What did Chang'e-5 do to the samples? Why? Answer: The sample was sealed. To ensure that the lunar samples were kept in a vacuum and unaffected by the external environment during their return to Earth. 5. What was the point of studying lunar soil? Answer: The study of lunar soil not only involved the moon itself, but also important information about the solar system's space materials and energy. It was beneficial to further understand the state of the moon, temperature, material content and other important information, and deepen the understanding of the lunar soil, lunar crust, and the formation and evolution of the moon. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is an example of a short popular science speech suitable for primary school students: Magical Science Dear teachers and students, Hello everyone! Today, I want to share with you some interesting scientific knowledge. Did you know? Science is everywhere around us. Just like the sun that we see every day, it is a huge star. It is very far away from us, but it brings us light and heat. Why? It turned out that there was a reaction called nuclear fusion going on inside the sun. It was like countless small bombs exploding inside, releasing a huge amount of energy. And the little marbles we play with, when they roll or collide on the ground, they also hide scientific principles. The rolling speed of the marble and the angle of collision would affect its final trajectory. This involved the knowledge of mechanics in physics. Science is amazing. It's in our lives, waiting for us to discover it. Let's stay curious and explore more mysteries of science! Thank you, everyone! maybe Entering the World of Science The students: Hello everyone! I want to talk about the science around me. Did everyone blow bubbles? The transparent and colorful bubbles were very fun. Why are bubbles round? This was due to the effect of surface tension. The molecules on the surface of the liquid were like a group of small hands. They all wanted to pull the bubble to the smallest surface area, and a circle was the shape with the smallest surface area under the same volume. The candy we eat has science too. The hard candy will become smaller and softer after a while in the mouth. This is because the temperature and saliva in our mouth slowly melt the candy. Science is in our lives. As long as we observe carefully, we can find many interesting things. Thank you! <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
