In future, when robots can be used both in homes and in other areas, it could improve the standard of living of people. House hold chores took significant cut in humans' life. Many people burn their energy on their day to day tasks like cooking, cleaning etc after coming from work. When robots can complete such jobs, people can spend more time with their family and friends. Experts say that many major problems in the modern world are caused due to miscommunication. When people get more time, they can talk freely and resolve such issues and eventually create happy society.

Robots can be used on certain jobs to curb accidents due to negligent behaviour of some people. When robots are used on such work, it does not cause any human life due to accidents at the work places. Human resource can be efficiently used by involving humans to perform those tasks which demand human skills like critical thinking, problem solving etc while robots can be used on low end jobs like moving cargos, heavy weights lifting etc.

While some people talk about how robots can be useful to human, others voice their concerns like demotion in human values and creation of lazy society due to heavy dependency on robots. When robots become cheaper to produce, employers may prefer to use more robots than humans. As the technology constantly improves the capabilities of robots, it could undermine the values of humans.

Many people may rely on robots heavily. Some may even develop a habit of using robots on tasks that they can easily do. This could create lazy society. Humans could start to cherish robots at the expense of human lives.

In conclusion, robots can be used on anything which can eventually improve humans' standard of living but definitely not at the expense of human lives. Robots can be used to help humans to live in harmony and to form happy societies. This fundamental setup should not be allowed to deteriorate by robots.

On the occasion of my tenth birthday, my dad gave me a great robot.

This robot looks like a little kid. He was only about two inches tall, he was made of a light hard plastic and light blue.

The big head like a square box placed on the body, not see the neck makes him look strangely strange! There are two antennae on each side, with two large ears, such as two halves of orange attached to the sides of the head with two very large round screws. My body as well as the rectangular box upright, there are lines decorated decorations look like he wears an armor. Behind the back there was a small hollow of two small batteries, close to the knob knob black switch. Two hands and two feet are also connected by small square boxes and attached to the body by large screws. Thanks to this, the limbs can turn in easy directions.

I turn on the switch knob, immediately the robot works immediately. From his belly, the shouts emit as his legs begin to move. Legs step by step step by step, his hands waving to the steps. The most funny thing is that the head looks right, then turns to the left as a hunt for the enemy. Going, touching the bottom of the table or the corner of the cabinet, you automatically avoid the other direction. The shouts and footsteps of the uncle led the cockroaches in the corner of the panic fled.

I love playing with this robot, I see you as a quiet and intelligent little friend.

In my freetime, I love to dance. When I was a little girl I danced all the time. My mother put me in dance school when I was 3 years old. My first dance dress was pink and it was love a ballet dress. Our dance group’s firts show was when we were 5 years old. We looked like pinguis. In 9 years we have had a lot of dance shows. I have danced for 9 years in the same dance company. But now everyone has joined other dance groups.

When I dance I forget everything else and I focus only on danceing. It was relaxing and it makes me happy. I like to take care of my body and dancing enhances your condition.

But now when I’m in High school I do not have time to dance. It’s so sad. I miss dancing . I hope that I have time to dance again day.

Giống: Có cấu tạo từ 1 tế bào, có kích thước hiển vi, dị dưỡng, có cách sinh sản là phân đôi, cách di chuyển là vừa tiến vừa xoay, hô hấp qua màng cơ thể

Câu 3. Trùng biến hình bắt mồi bằng chân giả, tiêu hóa mồi bằng không bào tiêu hóa, bài tiết bằng không bào co bóp, hô hấp qua màng cơ thể. Còn trùng giày bắt mồi bằng lông bơi(thức ăn vào miệng). Thức ăn vào miệng=> hầu tiêu hóa nhờ enzim trong không bào tiêu hóa=>thải bã qua lỗ thoát.

Quá trình bắt mồi và tiêu hoá mồi của trùng biến hình:
Trùng biến hình bắt mồi bằng chân giả.
Đầu tiên trùng biến hình tiếp cận con mồi, dùng chân giả vây lấy mồi. Sau đó một chân giả dài ra nuốt mồi vào trong. Mồi được nuốt vào ở vị trí nào thì ở đó hình thành không bào tiêu hoá. Không bào tiêu hoá bao lấy mồi tiết enzim tiêu hoá mồi. Chất dinh dưỡng được hấp thụ còn lại chất thải và chất cặn bã được đẩy ra ngoài qua bề mặt cơ thể.

1.Trùng biến hình sống ớ mặt bùn trong các hồ tù hay hồ nước lặng, dôi khi chung nổi lẫn vào lớp váng trôn mật các ao hồ.
Trùng biên hình lã cơ thể đơn bào, di chuyển bằng chân giả do sự chuyển động của chất nguyên sinh tạo thành.
Trùng biến hình bắt mồi (tảo, vi khuân, vụn hữu cơ,...) bằng cách tạo ra chân giả bao vây mồi, rồi hình thành không bào tiêu hóa để tiêu hóa mồi.

2.Trùng giày di chuyên vừa tiên vừa xoay nhờ các lông bơi rung động theo kiêu lần sóng và mọc theo vòng xoắn quanh cơ thể.
Thức ăn (gồm vi khuẩn, vụn hữu cơ,...) dược lông bơi dồn về lỗ miệng. Thức ăn qua miệng và hầu dược vo thành viên trong không báo tiêu hoa. Sau đó không bào tiêu hóa rời hầu di chuyến trong cơ thể theo một quỹ đạo nhất định. Enzim tiêu hóa biến thức ăn thành chất lỏng thấm vào chất nguyên sinh. Chất bã được thải ra ngoài qua lỗ thoát ờ thành cơ thế.
