In this contemporary era, social media has dramatically shifted people’s lives. Some people argue that social media brings advantages, whereas others believe they cause some disadvantages. I strongly agree that they have both positive and negative effects. Nevertheless, from my perspective, their influence is more harmful.
On the one hand, there are several reasons why social media provides some benefits. One of the main reasons is that modern social networking sites allow individuals to stay in touch with their friends and family quickly, no matter where they live. (On the one hand, social media provides some benefits because modern social networking sites allow individuals to stay in touch with their friends and family quickly, and share unlimited knowledge from which people can learn)For example, students studying abroad can consistently contact their parents and friends through video calls and messages on digital platforms. As a result, they can maintain close relationships and reduce feeling of loneliness. (Personal example)
On the other hand, social media also brings more severe negative effects. The significant factor is that millions of citizens, especially teenagers spend too much time in the virtual world which can reduce their study time, concentration span and even affect both their physical and mental well-being. (Example: concentration span) (Example: physical and mental well-being) Furthermore, some users and advertisements often portray unrealistic lifestyles, which may impact on incorrect values and inappropriate behavior with the youth. For instance, some celebrities show extreme beauty standards and luxurious lifestyles on the digital field which can lead to body image issues, low self-esteem, and unhealthy diet habits for teenagers.
In conclusion, although social media has certain positive effects, I believe the disadvantages outweigh the advantages, especially for the younger generation. Therefore, families, schools, and governments have to work together to promote digital awareness and enhance healthy online behavior.

更改顏色:
紅色: 用字錯誤、冗言贅字
橘色: 文法錯誤
紫色: 邏輯錯誤
藍色: 補述說明
大方向:
1. 這題是agree/disagree題型,所以你應該選擇一個立場,並下去寫,但你寫成Discussion題型,討論了社群媒體的好處跟壞處
2. topic sentence是一段文章的門面,會希望學生在這裡就要加上「自己的立場」(如紫色標注)。第二段的topic sentence, 你寫說: “On the one hand, there are several reasons why social media provides some benefits.” 會讓讀者有斷點,不知道重點在哪裡,雖然你後面馬上補起來理由是什麼,但把後面的跟前面的句子連接起來,就會很完美
3. 文章篇幅不夠,有兩種改法–
一種方法是延伸下去寫自己的經驗,多去描述自己的親身體驗
一種方法是新增觀點(如藍色標注)
4.舉例盡量兩個就好了
