A Russian robotics company has recently made headlines for offering $200,000（about 1,274,060 yuan) for the right to use one individual's face and voice forever in robot development. It's expected that their robots will look and sound human like. However, they may not be able to move like humans.

"Robots are klutzes (笨手笨脚的人)," US AI engineer Ken Goldberg told the website Science News for Students.

Robotic scientists say that one-year-old human babies have better movement skills than robots do. Let's take a look at some tasks that are easy for you but tough for robots.

Pick things up

Picking things up is not easy. If we drop our pencil on the floor, our brains work hard. First, we must find the pencil and look at its distance. Then we move our hands to it. A robot cannot always move it's"hand"to the right place. Calculating (计算) the distance is not easy. Then, when we touch the pencil, it might roll a little bit. Robots cannot easily understand this either. So, if you drop a pencil on the floor, a robot will probably roll it around the room.

Get around spaces

If someone drops you in a building you've never been to, you might feel a bit lost. But you can look around, find a door and get out quickly. You will not get stuck in a corner. But a robot will look everywhere for a door, even on ceilings and floors. This is because it's hard for them to understand spaces, especially large, blank things such as walls or ceilings. Scientists need to train them with lots of data to learn this.

Understand the world made by people

"Common sense" is what we don't need to think or talk about. Because of common sense, we do not look for doors on the ceiling. We pick up a coffee cup by its handle. We feel whether it has coffee inside, and whether it is hot.

But robots may turn the cup upside down or hold the hot part of the cup, damaging itself. Scientists have tried teaching robots common-sense rules. But even huge databases don't help much. There are just too many rules – and too many exceptions (例外). Maybe they just need more time to learn.

1. （1） Why is it difficult for a robot to pick things up?

   A . It cannot locate where the thing is. B . Its hands cannot move far enough. C . It has difficulty working out the exact distance. D . It tends to roll things around the room.
3. （2） What do robots tend to do when they are trapped in a corner?

   A . Look for doors aimlessly. B . Go to a door and get out. C . Wait for others to help. D . Check the space carefully.
5. （3） Why is it hard to teach robots common-sense rules?

   A . It is difficult to explain to them these rules. B . There are so many rules and unexpected situations. C . There aren't huge databases for the robots to learn from. D . It takes time and patience to teach them.
7. （4） What is the theme of the article?

   A . How robots help improve our lives. B . Robots have their own limitations. C . The importance of the database to robots. D . In what areas robots will be applied.
