3. Use the mind map below to write a paragraph (80 - 100 words) about the possible problems of having a home robot. Sử dụng sơ đồ tư duy dưới đây để viết một đoạn văn (80 - 100 từ) về những vấn đề có thể xảy ra khi có một người máy trong nhà.

Gợi ý

People can face some problems if they own a home robot. First, robots are expensive, so not every family can afford to have one. Second, people can become lazy because the robot does things for them. In addition, robots can’t do all things as well as humans can do. For example, robots can do the cooking but they cannot taste a dish to check if it is good enough. Furthermore, robots cannot do everything. They can only do things that they are programmed. So you should think carefully before buying a robot.
