Living in a smart city has both advantages and disadvantages. On the one hand, smart cities make life more convenient and comfortable. Modern technology helps reduce traffic jams, save energy, and improve public services. People can also enjoy a cleaner and safer environment thanks to smart systems and surveillance cameras

On the other hand, living in a smart city can be expensive because building and maintaining new technology costs a lot. Privacy is also a big concern since people's data may be collected and shared

In conclusion, smart cities bring many benefits, but they also have some problems that need to be carefully managed

Topic: Should parents strictly limit teenagers’ screen time?

In my opinion, parents should strictly limit teenagers’ screen time.

First, teenagers spend too much time watching social media or playing online games, and this leaves them little time for homework or family activities. As a result, their school performance can become worse.

Second, spending too much time in front of screens is bad for teenagers’ health. It can damage their eyesight, reduce their sleep time, and even cause weight gain.

For these reasons, I believe that parents should set clear rules about screen time and encourage their children to spend more time studying, exercising, and communicating in real life.
