Misleading content will not only undermine the credibility of the essay but also misguide readers. 4 However, you should avoid using too many professional terms; if you have to use them, be sure to explain them in simple language. For example, when mentioning “microgravity,” you can describe it as “a state where the body feels weightless, like floating in water.” 5 For instance, introducing the process of China’s Chang’e lunar exploration mission can make abstract knowledge about lunar landing more intuitive and vivid.
