Title：The Influence of Social Media on People's Life

Social media has become an integral part of people’s daily life in recent years. Among various social media platforms, Facebook, Twitter and Instagram are the most popular ones. Although social media has brought convenience to our life, it also has a negative influence on people’s emotional and mental health, especially for young people.

Firstly, social media creates the pressure of self-presentation. People tend to present the nicest side of themselves on social media, including beautiful photos, fancy dining, and exciting travel experiences. This contributes to the phenomenon of social comparison, where users tend to compare themselves unfavourably to their peers. This can lead to a negative evaluation of one’s own life and a decrease in self-esteem.

Secondly, social media platforms are designed to keep users engaged for as long as possible, which leads to addiction, especially among young users. The constant scrolling through posts and feeds can lead to procrastination and a loss of productivity, ultimately impacting one's mental health. In addition, the use of mostly visual communication on social media platforms reduces the amount of time spent reading books and other long-form content, ultimately negatively impacting user’s comprehension capabilities.

Lastly, social media can negatively impact face-to-face communication skills. Instead of engaging in face-to-face interactions, users rely more on virtual communication. This can lead to the lack of social and communication skills, ultimately negatively impacting relationships and personal lives.

In conclusion, while social media does provide some convenience in our daily communication and entertainment, it's important to recognise that social media can have long-term negative effects on our emotional and mental health if we're not careful and intentional about its usage. Therefore it is important to use it in moderation and maintain a balanced lifestyle.

近几年，电子商务已经逐渐成为了一种全新的购买方式，越来越多的人开始选择在网上购物，这也引起了不少争议。对于这一现象，有人认为网上购物可以方便快捷，而有人则认为它存在一些风险和不便之处。本文将就网上购物的利弊进行探讨。

首先，网上购物的最显著的优点就在于它的便捷性。在网上购物时，只需要打开电脑或手机，在家里或办公室就可以浏览各种商品，选择心仪的商品并下单，一切都可以在家中完成，省时省力，而且不必到店里跑腿。网上购物还可以为消费者提供更宽广的选择。许多商品在实体店里无法看到或是很难找到，在网上购物时就可以轻易地找到并购买。此外，因为网上商家降低了许多成本，网购的商品通常会比实体店里的商品价格更便宜，还可以通过促销活动和卡券等方式享受更多的实惠。

当然，网上购物也存在一些不方便和风险。首先，消费者无法亲自检查商品的质量，有时候网购的商品质量并不如实体店里的好，这就需要在退货方面有一定的规避。其次，网上购物也存在虚假商家和假冒伪劣商品的风险，消费者在网上遇到这种情况就需要小心**，保护自己的权益。此外，网上购物也有可能受到信息泄露、网络诈骗等安全问题的困扰，消费者必须要有常识和安全意识，提高自我保护能力。

总之，网上购物的利弊并存。消费者可以在享受便捷、宽广选择和更实惠的价格的同时，也必须注意规避风险和保护自身权益，只有这样才能够充分地利用网上购物的便利，让它成为自己的一种购物选择。
