They can cook, make tea or coffee, and clean our houses: Home robots.

They can teach children instead of human teachers: Teaching robots.

They can build buildings, bridges and roads: Worker robots.

They can help us find and repair problems in our bodies: Doctor robots.

They can build space stations on the moon and other planets: Space robots.

I agree with the idea that in the future robots will be very useful to us. Firstly, robots can be made of non-biological materials, rendering them able to withstand environments too toxic, too high or low temperatures, or having other conditions unsuitable for human workers. Secondly, robots do not need to be fed "food" in the traditional sense. They can operate using electricity from a variety of sources. In space, such electricity can come from the sun via solar cells or from fuel carried on board used to make electricity. Thirdly, robots do not get tired, and they can work long hours in dangerous locations that would wear out most astronauts. Fourthly, robots can be equipped with sensors and tools that are more sophisated than the human eyes or ears or hands, rendering robots capable of highly complex tasks. Lastly, robots do not age over time. For long interstellar journeys, they can be placed in a dormant state, to be waken up months or years later ready to go to work. For these reasons and others, robots are ideal machines for use in building space stations on many planets.

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?

A. criticize  

B. admire    

C. appreciate         

D. disapprove
