I'm reading a novel in m room now
Children today are too dependent on computers and electronic entertainment. It would be better for them to be outside playing sports and taking part in more traditional past times than spending all day indoors. Do you agree or disagree with this statement?
I agree with this statement because playing outside will reduce stress, while using the computer for too long will lead to eye damage.
Viết đoạn văn về chủ đề dưới đây:
Do you agree or disagree with the following idea?
"Robots will only bring benefits to people in the future"
You can use these clues:
- Introduction: disagree that robot will only bring benefits to people in the future.
- Idea 1: expensive
- Idea 2: make workers jobless
- Idea 3: we become lazy and inactive
- Conclusion: not always good for qualities of lives.
Today, robots are used in factories all over the world because robots are more efficient and accurate than humans. Robots can work long hours without any salary and food, don't need sleep or rest, can't shake or shake like human hands do and can do jobs that people aren't available to. ready to do. It must be recognized that the ability of the robot to work is extremely durable, stable, low maintenance costs, high working efficiency. Using robots at work helps a lot for businesses in optimizing operations, saving costs, and improving the quality of the working environment. In addition, using robots can increase productivity at work, cause uniformity in product quality, safety for workers, but it is also harmful: Robots need a power supply. Volume, which can take the place of many people in factories, can store large amounts of data, but storing, accessing, and retrieving is not as efficient as the human brain. This limits how robots can help and interact with people, but robots are still useful for humans, so we still need robots.
