Answer:
The letter with the three reasons is below:
Dear brother:
I know that you are concerned because I have received very low grades lately, and although I understand your concern and your position as my older brother, I want to tell you through this letter what has happened: first of all, although it has been some time since we returned to have face-to-face classes, I feel that I had gotten a little used to those virtual classes that we received last year due to the pandemic, where I could attend my classes while listening to my favorite music, or had a television program of interest to me in the background In addition to the fact that I got used to the comfort of my home, where I did not need to move to high school, I could enjoy food with my family all the time and I felt a little more calm and comfortable to study from my room or living room from our home while I was able to enjoy all the comforts that our home provides, however, now that we are back to normal, I am getting used to it.
On the other hand, you already know that according to the theory of multiple intelligences there are eight of them, and not all of them can necessarily be applied to the school environment, I consider that under that theory my intelligence is the body, you know that I am very good at the sports and I am a fan of some of them such as American football, basketball and baseball, for which, although I do not excuse myself with it, I think that there is no subject beyond gymnastics that is provided to me, so I find it a little more difficult to quickly grasp the topics seen in high school, which differentiates me from many of my classmates who are very good empirically in subjects such as mathematics or English, finally, I consider that I have been a bit inapplicable, sometimes I think that I can make adequate use of my time to fulfill all my tasks, but later I realize that I underestimated the time it would take me a job or study for an exam, or at other times, the various entertainment media take away valuable time that I could use in my school activities, for which I apologize, with a sincere apology from someone who wants to improve, I know in advance that the effort and responsibility towards my homework will allow me to exceed my grades above, for which I am willing to promise you that from now on I will get better grades, I will surpass myself and I will be a younger brother of whom you are very proud.
Sincerely,
Your little brother.
Explanation:
In the letter I have used 3 of the most recurrent reasons for high school students to obtain low school grades, using them in a letter that could allow a student not only to expose them to an older brother or another family member, but also to commit to improve and leave go ahead.
I have boldly marked the beginning of each of the three reasons and used 454 words to construct the letter.
