It can be easy for some of teenagers to form bad habits. These bad habits, if     1     (leave) unchecked, could lead to more serious ones when they become adults. To prevent harmful habits like these from     2     (支配) a teenager’s life is essential. To change bad habits is never easy, even with many     3     (attempt). Aristotle once said: “We are     4     we repeatedly do.” We make a choice to do something, and then we repeat     5     over and over again. Soon that choice becomes automatic and forms a habit. The good news is that we can change by understanding how habits work. we must first learn about the “habit cycle”, which works like this: Firstly, a “cue”, an action, event, or situation. Then a “routine”, the regular action you take     6     response to the cue. Thirdly, there is the “reward”.

    7     (facilitate) a positive change in our bad habits, we must first examine our bad habit cycles and then try to adapt them. Many of us try to change bad habits quickly, and if we are not successful, we often become     8     (悲观的) and give up. In fact, the most successful way to change is not suddenly, but over a period of time. As the Chinese philosopher Lao Zi wrote, “A journey of a thousand miles     9     (begin) with a single step.” To reach the goal of change, a person must show some d     10     . After all, it is not easy to break bad habits.

4 . Waking up at the crack of dawn and going for a run might feel intimidating when you start trying to make it a habit. Weaving a significant new activity such as this into your regular routine obviously takes determination and time — but how much time is really needed to make that habit stick?

One popular idea suggests that it takes 21 days to solidify a habit. The “three-week theory” originated from the 1960 self-help book Psycho-Cybernetics, in which plastic surgeon Maxwell Maltz observed that it took his patients about 21 days to get used to their new appearance after surgery. Even without much solid research, the 21-day myth became widely accepted. It likely persisted because it seems like such a reasonable amount of time, Colin Camerer, a behavioral economist at the California Institute of Technology who has conducted research on habit formation, explains.

Almost a half century later, researchers finally gathered strong evidence that countered this idea. A significant 2009 study on habit creation found that habits developed in a range of 18 to 254 days; participants reported taking an average of about 66 days to reliably incorporate one of three new daily activities — eating a piece of fruit with lunch, drinking a bottle of water with lunch or running for 15 minutes before dinner. Consistent daily repetition was the biggest factor influencing whether a behavior would become part of an automatic daily routine, says Lally, who was the first author on the study.

The type of activity is also a factor. Last year a study conducted by Camerer and his colleagues showed that creating a handwashing habit took a few weeks, compared with the half year it took for people to develop an exercise habit. Handwashing, the study noted, is less complex than exercising and offers more opportunities to practice. The researchers also suggested that habit formation depends on the effort that a person puts into practicing an activity and on the presence of environmental cues that would remind them to carry out the behavior.

7 . ChatGPT has been banned by schools in New York and Los Angeles, out of concern that students may use it to cheat on assignments. Despite these concerns, educators needn’t fear Al technology will transform education. Instead, it will help students take ownership of their studies and learn real-life skills. Today’s students need instruction that equips them with the skills of reasoning, analysis and argumentation rather than memorizing basic information. And Al may be a useful tool that promotes these skills.

Our experience with Al is perhaps best understood when compared with previous disturbances in education. When printed books, for example, began to occur in the mid-1400s, university professors were filled with panic. At that time, lectures depended on a specific model: Professors read from their hand-written texts, while students hurriedly copied whatever they heard. If students could simply buy the books, teachers likely thought that they wouldn’t need to come to class. Yet in practice, printing had the opposite effect: The number of universities exploded along with the total number of books. The new technology disturbed the mechanical aspect of education, but in doing so it allowed educators to refocus on higher-level skills.

Similarly, ChatGPT will replace the mechanical production of text, but it won’t decrease the need for higher-level skills. Possessing the skills to ask the right questions or state the right opinions will become crucial as the production of a logical essay becomes a simple task for a machine. Al will serve as a tool for information gathering and mechanical organization, but it won’t remove the fundamental need for critical thinking.Schools must remember that education’s value isn’t a head full of facts but a person with the skill to use these facts with the available tools to enhance their impact on the world. Al is one of these tools and, when used strategically, can improve students’ learning and performance in ways not yet seen. Therefore, it is essential for schools to provide an education that trains students in how to use the available tools for information. Unless they adapt quickly to the changing trends of education, they will be left behind by rapid innovation and change.

8 . Some people only exercise self-discipline in the parts of their lives they think as necessities — such as turning up to work on time and getting the job done. But self-discipline is a skill that can be applied to every aspect of life. And the benefits can be great.     1     .

9 . Women and girls already struggle with gender inequality, but when extreme weather damages a community, the UN found that inequalities worsen.

To explore the complex links between gender and climate change, CNN worked with seven women photojournalists to document the challenges women and girls face. This visual project gives a snapshot of the numerous ways climate crisis is changing their lives, but also shows how they are fighting back.

The Center for Girls’ Education runs a series of programs in Nigeria to help girls stay in school. One in every five of the world’s children who are out of school is in Nigeria, according to UNICEF, and it is girls who are impacted the most. More than 10 million children between 5 and 14 years old are absent from classrooms across Nigeria, according to UNICEF. For girls, the statistics are even bleaker: in states in the northeast and northwest of the country, fewer than half attend school.

This education crisis is the result of a tangle of factors, but against the backdrop of these individual factors is the broader context of the climate crisis. Nigeria is growing hotter and dryer, and extreme weather such as flash floods and landslides are becoming fiercer and more frequent. Climate disasters can make schools inaccessible and classrooms unsafe. Communities struggling to cope with extreme weather sometimes turn to their children to help or to earn extra money to support the family. And girls, whose attendance at school is already discouraged in some communities, are often most affected.

There are efforts to support girls’ education and equip them with the resources to cope with a fast-changing climate. The Center for Girls’ Education in the northern Nigerian city of Zaria runs programs to help girls stay in school and offers training on how to cope with the impacts of extreme weather. “I feel when we give the girls education on climate change, how to ease it, it will go a long way in helping the girls in how to support themselves in times of difficulties, and even help them prepare for it,” said Habiba Mohammed, director of the Center for Girls’ Education.
