Unexpected connection between sleep and academic performance has been recently discovered.
Researchers have found that insufficient sleep and tiredness increase a person's risk of developing severe medical conditions, such as obesity （肥胖症），high blood sugar levels, and heart disease. Now, a new study has found that getting sufficient sleep is also the key to improving academic performance.
Jeffrey Gross, the university science professor who led the research, was not trying to find the relationship between sleep and grades when he handed out smartwatches to the 100 students in his chemistry class. Instead, the professor hoped the wrist-worn devices, which track a personas physical activity, would show a connection between exercise and academic achievements.
While Grosses data showed no relationship between these two factors, the study found something surprising. As the researchers were analyzing their data, they noticed that there was a linear （线性的）relationship between the average amount of sleep the students got and their results in the course's 11 quizzes, three midterm tests, and the final exam.
Even more interesting, it was not sufficient for students to just head to bed early the night before a test Instead, it's the sleep you get during the days when learning is happening that matters most.
When students went to bed each night was similarly important. Those who went to bed in the early hours of the morning performed poorly, even if the total sleep time was the same as a higher-performing student. "When you go to bed matters," Gross says. “If you go to bed at 10, or 12, or 1 at night, and sleep for seven hours, your performance is the same. But if you go to bed after 2, your performance starts to go down even if you get the same seven hours' sleep. So, quantity isn't everything."
Perhaps the most interesting was the huge impact that small differences in sleep patterns had on the students' grades. The overall course grades of students averaging six and a half hours of sleep each night were 25% lower than students who averaged just one hour more sleep. Similarly, students who varied their bedtime by even one hour each night had grades that dropped 45% below those with more regular bedtime.
Who knew getting straight AM just required some extra sleep?

Everything from essays to exams is threatened by advanced artificial intelligence like ChatGPT, which can produce clear answers to complex questions. Educators are particularly concerned about students turning to AI tools like ChatGPT with their homework. One suggested solution is to make students write exam essays using pen and paper.
To stay competitive through their careers, students need to learn how to use AI writing tools properly to gain output.
In addition to the sound reasons for treating ChatGPT as an opportunity and not a threat, there are practical ones. It simply isn’t possible to effectively ban this technology. Many students can’t help using AI assistance while writing.
Writing is a skill worthy of great respect. But most students don’t have the desire to become professional writers. Instead, they are preparing for careers where they will write to further goals beyond the production of writing. As we do today, they will write to communicate, explain, request and persuade.
| A．The ban of ChatGPT would also produce the injustice. |
| B．There is argument that the use of ChatGPT is good for education. |
| C．AI writing tools, when properly used, will help them do those things better. |
| D．Learning to write without AI does indeed promote focused, disciplined thinking. |
| E．But that’s wrong to ban students from using labor-saving and time-saving AI writing tools. |
| F．Besides, the AI writing tools will always be one step ahead of the tools to discover AI text. |
| G．They need to learn to compose well-organized essays using AI-produced text and traditional writing. |
