1. **it is said that should be careful in the development of robots**
- **should be**: Câu này thiếu chủ ngữ, nên cần thêm "we" hoặc "people" trước "should be".
- Sửa lại: **it is said that we should be careful in the development of robots
2. with the advances of information technology, robots will be able serving people in restaurant
- advances of : Thường thì ta dùng "advances in" thay vì "advances of".
- serving: Sau "be able" cần dùng động từ nguyên thể, nên "serving" phải đổi thành "to serve".
- *in restaurant*: Thiếu mạo từ "a" hoặc "the" trước "restaurant".
- Sửa lại: with the advances in information technology, robots will be able to serve people in restaurants
Vậy câu hoàn chỉnh sẽ là:
It is said that we should be careful in the development of robots. With the advances in information technology, robots will be able to serve people in restaurants
