Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.

Robots are useful for exploring and working in space. In particular, many robots have been sent to explore Mars. Such robots have usually looked like a box with wheels. Though these robots are useful, by their very nature they are unreliable, extremely expensive, and they break easily. Also, they cannot do very many tasks. Because of these problems, scientists have been developing a new and unusual kind of robot. These new robots move like snakes, so they have been given the name "snakebots."

The way a snake is shaped lets it get into very small spaces, like cracks in rocks. It can also push its way below the ground or climb up different kinds of objects, like high rocks and trees. Such abilities account for the usefulness of a robot designed like a snake. A snakebot would be able to do these things, too, making it much more effective than regular robots with wheels, which easily get stuck or fall over. Since they can carry tools, snakebots would be able to work in space, as well. They could, for example, help repair the International Space Station.

But how can such a robot shape be made? A snakebot is built like a Chain made of about thirty parts, or modules. Each module is basically the same in that they all have a small computer and a wheel to aid movement. The large computer in the "head” of the snake makes all of the modules in a snakebot work together.

The modular design of the snakebot has many advantages. If one module fails, another can be added easily. Snakebot modules can also carry different kinds of tools, as well as cameras. Since each module is actually a robot in itself, one module can work apart from the rest if necessary. That is, all the modules can separate and move on their own, and then later, reconnect back into a larger robot. Researchers are also trying to develop snakebots made of a special kind of plastic that can change its shape using electricity, almost like animal muscles. Snakebots made with this plastic will be very strong and hard to break.

Overall, the snakebot design is much simpler than that of common robots. Thus, snakebots will be much less expensive to build. For example, a robot recently sent to Mars cost over a hundred million dollars, whereas snakebots can cost as little as a few hundred dollars. With their versatility and affordability, snakebots seem to be the wave of the future, at least as far as space robots are concerned.

Which of the following best describes the attitude of the author toward the new kind of robot?

Though these robots are useful, by their very nature they are unreliable, extremely expensive, and they break easily. Also, they cannot do very many tasks. Because of these problems, scientists have been developing a new and unusual kind of robot. These new robots move like snakes, so they have been given the name “snakebots.”

(Rô bốt rất hữu ích cho việc khám phá và làm việc trong không gian. Đặc biệt, nhiều rô bốt đã được đưa lên khám phá sao Hỏa. Những con rô bốt này thường trông như 1 cái hộp có bánh xe. Mặc dù những con rô bốt này khá hữu ích, nhưng đương nhiên là chúng không chắc chắn, cực kì đắt đỏ và dễ bị vỡ. Hơn nữa, chúng cũng không thể thực hiện quá nhiều nhiệm vụ. Bởi vì các hạn chế đó, các nhà khoa học đang phát triển một loại rô bốt mới và khác lạ. Những con rô bốt mới này di chuyển như những con rắn, vì vậy

Read the following passage and mark the letter A, B, c, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42.

Most of us associate robots with films such as Star Wars, I, Robot or AI, but in reality they have more to do with social issues and politics rather than science fiction. The term robot first made its appearance in a play entitled Rossum s Universal Robots written almost a century ago by a Czechoslovakian playwright by the name of Karel Capek. Capek got the name robot from the Slavic word ‘ robota’ which means forced labour. In his play, he portrays a society where robots, which look human, are mass produced to work in the place of people.

Capeks story was well received by the critics but never really got credit for being the source of the notion of robots. The play has significant relevance to our society today, as humanoid-type robots are being created to fulfil a wide range of tasks. Robot engineers are not only developing mindless worker drones, but are attempting to create human-like companion robots for people. Consequently, the question of what actually makes us human is the subject of lively debate.

In the USA, sociable robotics is developing at a relatively rapid rate and a human companion type of robot could soon be a reality. Japanese researchers see a very bright future for these robots who will serve as friends or family to the lonely. Nevertheless, one needs to ask if a human being can have a relationship with a machine in the same way as they do with other people or animals and if so, what effect this could have on our society. The success of robot toys or virtual pets suggests that this type of relationship is possible.

Research shows that children tend to have similar relationships with humans as with non-humans whereas the same is true for adults only with pets or when the robot is designed to look like a child. This is probably because robots display superficial emotions and cannot as yet replace human touch. But will these machines one day succeed in replacing humans?

Some paint a very dark picture of a robot society and predict that artificially intelligent machines will take control of the entire planet and dominate the human race. However robot technology is still in its infancy and the idea of them taking over the world is pure fantasy to most of us, including scientists. In fact, most robots can only perform very basic tasks and even the most advanced robot that is capable of expressing over forty different emotions seems to do so in a totally random manner, regardless of what is going on around it.

In spite of the simplicity of today’s robots, robotic technology is impacting our everyday lives in a dramatic way. Nowadays, our robots are becoming more and more like those portrayed in Capeks work. In a society where human relationships are so often strained, it is no surprise that the possibility for human-robot relationships is increasing.

Japanese researchers think that robots could _____________ .

A. be useful to engineers

B. be put to use as servants

C. be of use to families

D. be of use to people who live alone
