Nội dung bài nghe

Good evening. I'm Mrs. Jones. I'd like to thank all you parents for coming to this school meeting tonight. These days, social media has become popular with our students. However, it also has many risks we need to know about to protect our students and children. Cyber bullying is the biggest risk to teens. People online tried to harm others by saying hurtful things. This is called troll behavior. In fact, 60% of teens who use social media have experienced bullying. Bullies do this because it makes them feel better about problems in their lives. Students who are bullied should tell their parents or teacher and block the bully. The second biggest risk for teens is online predators. They meet kids and social media groups and act like they are a kid too. They might offer a kid a gift to try to meet them. They do this so they can hurt kids or take them away from their families. Children should never give out personal information or meet people they don't know. The last risk I want to discuss is online scams. On social media dangerous people will try to get children's personal information. They can send kids messages or emails that can damage their computer too. We have to teach our students not to open emails from people they don't know. They should also only go to websites that they know and trust. Social media will be safer if students follow these suggestions. Does anyone have any questions?

c. In pairs: What are some other social media risks for teens? Theo cặp: Một số rủi ro truyền thông xã hội khác đối với thanh thiếu niên là gì?

Đáp án

A: What are some other social media risks for teens?

B: I think one big risk is addiction. Many teenagers spend too much time online and it affects their sleep and schoolwork.

A: That’s true. Also, some teens compare themselves to others and feel bad about their appearance or life. That’s called low self-esteem, right?

B: Yes, exactly. And don’t forget about privacy risks. Sometimes teens share too much personal information without realizing the danger.

A: Good point. There’s also the risk of fake news or misinformation. Teens might believe things that aren’t true.

B: Right! So social media can be fun, but it’s important to use it wisely.

Reading

a. Read David's essay and tick the best title. Đọc bài luận của David và đánh dấu vào tiêu đề hay nhất.

1. Dangers of social media

2. How to make social media safer

3. Why teens use social media

Social media has become very popular. However, it has many risks for teens. This essay will explain the biggest risks of social media and give some ideas on how to avoid them.

One of the biggest things teens need to understand is that the things they post are permanent. If they post on social media today, it could affect their life in the future. Teens may post things that can make them look like bad people, and in the future, a company could find these. Many people have lost their jobs because of things they posted years ago, so teens need to be careful what they post now.

The second biggest risk for teens is social media addiction. Too much time on social media means less time studying, seeing friends, or doing extracurricular activities. It can affect their ability to communicate with people, and it also causes their grades to go down. Teenagers should limit their time on social media and spend more time interacting with friends in person.

The last risk I want to talk about is malware and viruses. Teens need to understand that they can get malware by downloading bad software and get viruses by clicking a link or visiting a bad website on social media. These slow down the computer and can even destroy important files. Teens should always have good antivirus software, and never click on strange links or take files from strangers.

In conclusion, we all know that social media is a big part of most teens lives now. It can be interesting and fun, but using it carelessly can also be risky. However, if teens think about what they post, spend less time online, and are careful about possible threats, then social media can be used safely.

Đáp án

A: Do you agree with David about the three biggest dangers on social media?

B: Yes, I do. I think he made some very good points. For example, I agree that what you post online can affect your future. People don’t always realize that posts can stay forever.

A: I agree too. Some teens post silly or angry things, and later they regret it. It could hurt their chances of getting a job or going to a good school.

B: Exactly. I also think social media addiction is a big problem. Some teens spend hours scrolling and don’t focus on studying or spending time with real friends.

A: True. I’ve seen some friends ignore people in real life just to stay on their phone. It’s kind of sad.

B: And about malware and viruses—I think that’s also a serious danger. Many teens don’t even know what malware is.

A: Yeah, they just click on random links or download things without thinking.

B: So yes, I agree with David. Those three dangers—permanent posts, addiction, and malware—are real risks that teens should be more careful about.

Gợi ý

In today’s digital age, the internet offers many benefits to teenagers, such as entertainment, education, and social connection. However, it also presents serious risks that can negatively affect their well-being. One of the biggest dangers is cyberbullying, where teenagers are harassed or threatened online. Another major risk is online predators, who may try to gain teenagers’ trust and then exploit or harm them. Additionally, exposure to harmful content, such as violence or inappropriate materials, can influence young minds in damaging ways.

To solve these problems, both parents and schools need to take action. First, parents should educate their children about online safety and set clear rules for internet use. Open communication helps teenagers feel comfortable reporting any suspicious or harmful behavior. Second, schools can offer digital safety lessons, teaching students how to recognize threats and protect their personal information. Finally, social media platforms and websites must improve monitoring systems to detect and block harmful content or users.

In conclusion, while the internet is a powerful tool for learning and connection, it also comes with risks for teenagers. Through education, open communication, and strong online protections, we can help keep them safe in the digital world.
