Why does social media trigger feelings of loneliness and inadequacy? Because instead of being real life, it is, for the most part, impression management, a way of marketing yourself, carefully choosing and filtering the pictures and words to put your best face forward.

        Online “friends” made through social media do not follow the normal psychological progression of an interpersonal relationship. You share neither physical time nor emotional conversations over the Internet. You simply communicate photographs and catchy posts to a diverse group of people whom you have “friended” or “followed” based on an accidental interaction. This is not to say that your social media friends can’t be real friends. They absolutely can, but the two are not synonymous. Generally speaking, there are no unfiltered comments or casually taken photos on our social media pages. And, rightfully so, because it wouldn’t feel safe to be completely authentic and vulnerable with some of our “friends” whom we don’t actually know or with whom trust has yet to be built.

        Social media can certainly be an escape from the daily grind, but we must be cautioned against the negative effects, such as addiction, on a person’s overall psychological well-being.

        As humans, we yearn for social connection. Scrolling (滚动) through pages of pictures and comments, however, does not provide the same degree of fulfillment as face to face interactions do. Also, we tend to idealize others’ lives and compare our downfalls to their greatest accomplishments, ending in feelings of loneliness and inadequacy.

        Social media can lead people on the unhealthy quest for perfection. Some people begin to attend certain events or travel to different places so that they can snap that “perfect” photo. They begin to seek validation through the number of people who “like” their posts. In order for it to play a psychologically healthy role in your social life, social media should supplement an already healthy social network. Pictures and posts should be byproducts of life’s treasured moments and fun times, not the planned and calculated image that one is putting out into cyberspace in an attempt to fill insecurities or unmet needs.

        Ultimately, social media has increased our ability to connect with various types of people all over the globe. It has opened doors for businesses and allowed us to stay connected to people whom we may not otherwise get to follow. However, social media should feel like a fun experience, not one that contributes to negative thoughts and feelings. If the latter is the case, increasing face to face time with trusted friends, and minimizing time scrolling online, will prove to be a reminder that your social network is much more rewarding than any “like”, “follow” or “share” can be.

解析：A。本题为观点态度题，需要结合题干和原文语境理解。根据题干中的pictures and posts on social media和题文同序原则可定位到第五段最后一句，该句指出，图片和帖子应该是生活中珍贵时刻和欢乐时光的衍生品，而不是为了填补自己的不安全感或实现自己未曾满足的需求，而在网络空间精心策划的形象。也就是说，图片和帖子应该是用来记录美好时刻的，而不是刻意营造、精心策划的形象。A项与此内容相符，其中memorable moments对应定位句中的treasured moments and fun times，故A项为正确答案。

错项排除：B项中的best image利用第五段第二句中的“perfect” photo设置干扰，但原文中说的是人们为了追求完美的照片而刻意去参加活动或旅行，并没有提到社交媒体上的图片和帖子应该被精心编辑，故B项排除。C项利用第二段最后一句中的it wouldn’t feel safe设置干扰，但原文中提到的是在不熟或不信任的网友面前完全展现自己真实和脆弱的一面，会让人感到不安全，在第五段最后作者提到，图片和帖子不应该是为了填补自己的不安全感，C项与此内容相悖，故错误。第五段开始说社交媒体会导致人们对完美的病态追求，并不是说社交媒体上的图片和帖子应该阻止人们对完美的病态追求，故D项排除。
