Intelligent Robots play a vital role in modern days. Besides benefits, we must consider disadvantages when using them.

First, look at the most positive points. Thanks to robots and A.I technology, the number of workforce can be reduced but the production even increases more, especially in the manufacturing industry. The robots can perform the tasks faster than the humans and much more consistently and accurately. They can work at places 24/7 without any salary and food. Additionally, they don’t get bored. In medicine, they helps doctors to diagnose diseases, do the surgeries, especially tiny surgeries with highest accuracy. In some hospitals, the robotic pets can help the patients with depression and they keep them active.

On the contrary, robots bring about some troubles. First and for most, training is needed to operate the system, so we need to pay for scientists and trainees, maintenance and reparation expenditure, which raise the cost overall. Another point I’d like to mention is the machine malfunction, which creates lots of troubles and confusions, and even sometimes lead to unexpected accidents. It’s reported that a robot in a car manufacturing factory killed a worker. This results in a worrisome of people using A.I for medical purposes. Furthermore, the robots are not able to act any different from what they are programmed to do. With the heavy application of robots, the humans may become overly dependent on the machines, losing their mental capacities. If the control of robots goes in the wrong hands, the robots may cause the destruction.

In conclusion, I suppose that we need to take advantages of A.I to make our life better, but remember its dangers and risks to take precaution timely.

As we are human we naturally need to rest on leisure time to recover thestress of work and everyday life. In fact, every individual need to do what they want and belong to them. Personally, I prefer to be active during this time because it is feel right to me better. Moreover, people are free for what they do on their leisure time, and nobody can say what it is the best.

Some people want to relax after their day of work. These people may prefer to relax by watching movies, reading or getting a massage. People who have a physically jobs such as doctors, teachers and builders may choose these types of activities. If you are a doctor, you may feel that you want to let your body rest after work and you don’t want to do a five kilometer run after work, because you are already physically tired.

On the other hand, some people choose to be active in their leisure time because they do very sitting jobs. For example, these people many spend all day sitting on a chair and do their work. At the end of a working day, they may be have a backache, and all of their body become tired so they need to stretch their arms and improve their health by doing some activity such as going to the gym or swimming.

To sum up, the important thing is that people want to stay healthy by choosing what is best for them. In my view, the wrong way is to stay at home in your leisure time if you have a setting job.

Solar energy captured by solar panels is a limitless form of energy, as the earth is bombarded with extreme amounts of solar energy every day, according to the National Renewable Energy Laboratory. It's also clean, producing no carbon dioxide, and is very low-maintenance, since solar panels have no moving parts.

Unfortunately, the National Renewable Energy Laboratory says its high installation cost makes it up to four times more expensive than the cost of electricity from a standard utility company. For optimal operation and maximum energy production, it requires year-round sunny weather and is very expensive if repair is necessary, according to the U.S. Environmental Protection Agency

Năng lượng mặt trời thu được bởi các tấm pin mặt trời là một dạng năng lượng vô hạn, vì trái đất bị bắn phá với lượng năng lượng mặt trời cực lớn mỗi ngày, theo Phòng thí nghiệm năng lượng tái tạo quốc gia. Nó cũng sạch sẽ, không tạo ra khí cacbonic và bảo dưỡng rất thấp, vì các tấm pin mặt trời không có bộ phận chuyển động. Thật không may, Phòng thí nghiệm năng lượng tái tạo quốc gia cho biết chi phí lắp đặt cao của nó làm cho nó đắt hơn gấp bốn lần so với chi phí điện từ một công ty tiện ích tiêu chuẩn. Để hoạt động tối ưu và sản xuất năng lượng tối đa, nó đòi hỏi thời tiết nắng quanh năm và rất tốn kém nếu sửa chữa là cần thiết, theo Cơ quan Bảo vệ Môi trường Hoa Kỳ
