Robots may seem smart, but they cannot even pick up a chess piece. Let’s take a look at some tasks that are easy for kids but not 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. Then we move our hands to it. A robot cannot always move its “hand” to the right place. When we touch the pencil, it might roll（滚动） 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 in large space

If someone drops us in a building we’ve never been to, we might feel a bit lost. But we can look around, find a door and get out quickly. But a robot will look everywhere for a door, even on ceilings（天花板） and floors. This is because it’s hard for them to understand spaces, especially large, blank things such as walls or ceilings.

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（把手）. We feel whether it has coffee inside, and whether it’s hot.

A robot? It may turn the cup upside down. It may hold the hot part of the cup. Scientists have tried teaching robots common-sense rules. But even huge databases（数据库） don’t help much. Maybe they need more time to learn.

（1）What may happen when a robot tries to pick up a pencil?

A．	It may break the pencil.	B．	It may roll the pencil.
C．	It may not find the pencil.	D．	It may watch the pencil roll.

（2）What will a robot do in order to find a door?

A．	Dig a big hole in the wall.	B．	Only look for large and blank things.
C．	Search everywhere even the ceilings.	D．	Drop itself in a corner in the building.

（3）What can we learn about common sense from the last two paragraphs?

A．	Robots can teach themselves common sense.
B．	Robots have the same common sense as humans.
C．	Scientists tried teaching robots common-sense rules.
D．	Huge databases help much for robots to learn common sense.

（4）What can we learn from the passage?

A．	Robots are not helpful to humans at all.	B．	Robots are good at picking up small things.
C．	It is easy for robots to understand large spaces.	D．	Robots have trouble understanding our world.

As we can learn from the story in our textbook, guide dogs are the “eyes” of blind people. But how can they be so helpful? The answer is simple. Guide dogs practice to be helpful. As part of the training, guide dogs practice getting to the places their owners will need to go. But before this, guide dogs must receive training in many other areas. This is because guiding a person safely is more important than just knowing where to go.

Suppose a tree branch（树枝） is lying on the road in front of a blind person and his guide dog. Since the person cannot see the branch, it’s up to the dog to let him know it is there. If the branch is small the dog may help guide its owner around it. If it is large, the dog will stop the person. Then he knows there is something in the way. He will work with his dog to find a way past the branch.

Many people think a guide dog tells its owner when they can cross the road. This is not true. Instead, the dog usually stops its owner when they have reached the end of a road. Then the blind person listens to their situation and considers if it is safe to cross the road. A blind person and his dog always work as a team.

（1）About guide dogs, we can know ________ from the first paragraph.

A．	blind people can’t afford a guide dog	B．	not all dogs can be trained to be helpful
C．	dogs are born to be helpful to blind people	D．	guide dogs learn to be helpful through training

（2）The underlined word “it” in Paragraph 2 refers to “________”.

A．

the road

B．

the tree branch

C．

the blind person

D．

the dog

（3）If there is a large branch on the road in front of its owner, the guide dog will ________.

A．	stop its owner	B．	ask someone for help
C．	move it with its owner	D．	guide its owner around it

（4）According to the passage, who will decide if it is safe for a blind person to cross a road?

A．	The blind person himself.	B．	His guide dog.
C．	Both he and his guide dog.	D．	A police officer.
