英文介紹自己的科研項(xiàng)目

Introduction:

My research project is an ongoing effort to investigate the relationship between social media and mental health. I have been working on this project for several years now and have collected a large amount of data through surveys, interviews, and other means.

The purpose of my research is to understand how social media usage is linked to mental health problems, such as depression, anxiety, and addiction. I am interested in understanding why people use social media and what factors contribute to their use, as well as how social media can be used to improve mental health.

The research project involves a number of different aspects, including analyzing data from surveys and interviews to identify patterns and trends in social media usage and mental health. I am also interested in exploring the impact of social media on people\’s relationships and social life, as well as their physical and mental well-being.

Overall, my research project aims to provide insights into the relationship between social media and mental health, and to contribute to the ongoing debate about the potential negative effects of social media usage.
