Is Social Media a Force for Good or Harm?
Social media platforms such as Facebook, Instagram, and Twitter have become an essential part of modern life. While they bring people together and give everyone a voice, many argue that they also cause serious problems.
On the positive side, social media allows us to keep in touch with friends and family, no matter where they are in the world. It also helps to spread information quickly, making it easier to learn about news and events. For small businesses, it provides a cheap way to advertise and reach new customers.
However, critics point out that social media can be a distraction, especially for young people who spend too much time scrolling through their feeds. Many users also worry about privacy, as personal data is often not well protected. Furthermore, misinformation can spread quickly on these platforms, leading people to believe things that are not true.
In my view, the effect of social media depends on how we use it. If we learn to check the reliability of what we read and manage our screen time, it can be a useful tool rather than a source of harm.

情景:一个社交媒体顾问在社区中心举办讲座,分享如何安全使用社交媒体(Section 2 独白)
Advisor
Good evening, everyone. My name is Linda Chen, and I'm a social media advisor. Tonight, I'd like to talk about how to use social media safely while still enjoying its benefits.
Advisor
First, let's discuss privacy settings. You should always check who can see your posts. I recommend setting your profile to 'friends only' rather than 'public.'
Advisor
Second, be careful about accepting friend requests from people you don't know. Not everyone online is who they say they are. There have been cases where fake accounts were used to gather personal information.
Advisor
Another important point is to think before you post. Once something is online, it can be hard to remove completely. You might have shared something that could hurt your reputation later.
Advisor
Finally, take regular breaks from social media. Spending too much time scrolling can affect your mental health. Try to limit your use to thirty minutes at a time, and avoid checking your phone before bed.
MCQ1.What does Linda recommend for privacy settings?
A Keep everything public
B Set profile to 'friends only'
C Delete all accounts
✅ B — 原句:I recommend setting your profile to 'friends only' rather than 'public'。
TFNG2.You should accept friend requests from anyone.
✅ FALSE — 她说 be careful about accepting friend requests from people you don't know。
gap_fill3.Linda advises taking regular breaks from social media and limiting use to ___ minutes at a time.
✅ thirty / 30 — Try to limit your use to thirty minutes at a time。
MCQ4.Why should you avoid checking your phone before bed?
A It wastes battery
B It can affect mental health
C It costs money
✅ B — Spending too much time scrolling can affect your mental health ... avoid checking your phone before bed。
Some people think that social media has a negative influence on our daily lives. Others believe it brings more benefits than drawbacks. Discuss both views and give your own opinion.
Social media has become a central part of daily life for billions of people. While it offers numerous advantages, such as staying connected with loved ones, others argue that it brings about more harm than good. This essay will examine both perspectives before concluding that the impact of social media largely depends on individual usage.
On the one hand, social media provides significant benefits. It allows people to keep in touch with friends and family across long distances, often at no cost. For instance, many grandparents can now see photos and updates of their grandchildren daily, which was impossible a few decades ago. Moreover, social media is a valuable source of information, enabling users to access news and educational content quickly. It also opens up business opportunities, allowing companies to advertise to a global audience with minimal expense.
On the other hand, there are serious concerns. One major issue is its effect on mental health; constant scrolling and the pressure to present a perfect life can cause anxiety and low self-esteem. Additionally, it is easy for false information to spread, sometimes with dangerous consequences. For example, if people had not shared unverified news stories during a recent health crisis, panic might not have been so widespread. Privacy is another worry, as many platforms collect vast amounts of personal data.
In my opinion, social media is neither entirely good nor bad. If used carefully and in moderation, the benefits can outweigh the disadvantages. However, if users fail to check facts or spend excessive time online, it can indeed be harmful. Therefore, I believe the key lies in educating people on responsible use rather than blaming the platforms themselves.
In conclusion, while social media presents both opportunities and threats, its overall effect is determined by how we choose to use it.

口语 Speaking
Part 1
Q: How often do you use social media?
I use it every day, perhaps a bit too much, to be honest. I mainly check Instagram and Facebook, usually in the evenings after work to relax and see what my friends are up to.
💡 具体说明频率+平台+目的,自然流畅。
Q: Do you think you could live without social media?
I'm sure I could, but it would be difficult at first. If I didn't have social media, I'd probably miss a lot of events and updates. That said, I might actually be more productive without the distraction.
💡 使用二类条件句反思,并加入让步(That said)。
Part 2 · 提示卡
Describe a time when you used social media to learn something useful. You should say: what you learned; which platform you used; how you found the information; and explain why it was useful.
A few months ago, I wanted to learn how to cook a specific Italian dish, so I turned to YouTube. I simply typed the name of the dish, and hundreds of step-by-step video recipes appeared. What I liked was that I could see the entire process visually, which is much easier than reading a recipe in a book. The video I chose had millions of views and was created by an experienced chef, so I felt it was quite reliable. I learned not only the ingredients and method, but also a few professional tips that made the dish much tastier. This was really useful because I was able to prepare the meal for a family gathering, and everyone loved it. If I hadn't checked the video before cooking, I'm sure I would have made several mistakes. Since then, I've used YouTube many times to learn other practical skills, like fixing a leaky tap or even basic car maintenance.
💡 完整回应所有要点,使用三类条件句(If I hadn't checked... I would have made),词汇恰当。
Part 3
Q: Why do you think social media is so popular among young people?
I think it's mainly because young people enjoy sharing their lives and seeing what others are doing. It gives them a sense of belonging and keeps them entertained. There's also the fear of missing out—if everyone is on a platform and you're not, you might feel left out. So it creates a kind of social pressure.
💡 分析原因,使用术语 fear of missing out,并给出解释。
Q: Do you think social media has changed the way we form relationships?
Absolutely. In the past, you had to meet someone face to face to build a friendship, but now many relationships start online. Social media makes it easier to find people with similar interests, but at the same time, some of these connections can be superficial. It's a trade-off between quantity and quality.
