A

Robots seem very new to most people. But they have a long history. The first one was made by a Greek(希腊人)inventor in the 1920s.You may have seen robots in some fields. The robots in these fields are stronger, faster and much cleverer than people. In real life, most robots are used in factories. They are used to do many dangerous, difficult or boring jobs. Some people can’t look after themselves and robots are used to help, for example, some people can’t see. Many of these people use a dog to help themselves move around. This dog is called a guide dog. Scientists are making a robot to help them. In the future, robot dogs might take the place of these guide dogs.

One kind of robot guide dog has wheels. It moves in front of the owner. It is very clever. It knows the speed of its owner’s walk. The owner wears a special belt(带子). This belt sends instr uctions to the owner from the dog, such as“Stop here”, “Turn left” or “Turn right”.

In the United States, another kind of robot helps disabled people to take care of themselves in their daily life. The robot hea rs the sound of its owner’s voice. It follows instructions such as “Turn the page” or“Make a cup of coffee”.

Robots are also used in American hospitals. At one hospital a robot take meals from the kitchen to the sick people’s rooms. It never loses its way because it has a map of the hospital in its computer memory.

In the future, robots will work in space. But robots will never take the place of human beings(人类).They can, however, help us in a lot difficult ways.

A. were invented a few years ago

C. can help the people who can’t see

( )42.The underlined phrase “a guide dog” means .

( )44. Robots can’t get lost in hospital, because .

B. they ask the people when they don’t know the way

C. their computer memory can tell the way

( )45. In the future, robots .

A. will work in difficult and important fields

B. will take the place of human

C. can’t do something as bad people tell them

B

What would the future life be like? I think we will be able to travel faster and safer around the world and into space.Maybe one day we can work in Beijing,sleep in Chengdu and visit the moon for a h oliday.

We will have new energy(能源)that doesn’t make pollution.Possibly,people will find ways to use cleaner things,such as sea water,to make energy without polluting the earth.

We will have machines that can copy everything in the futu re.Put a cake on the machine and it makes a new one.If the machine is like a faxmachine(传真机),we can send food and presents to our friends easily.

We will have clever robots that work for us,and then bring us usefulthings and take away our rubbish.Now we have to press a key or type a word to make a machine work.But in the future,if we think of something,the machine can make it for us.The machine can understand our ideas.

We will be able to go into computer games and films,and everything will feel real.We will be able to make our homes like forests or sunny beaches or anything we want.Perhaps,one day we will be able to collect our dreams and put them on DVDs.

阅读上述短文，判断句子正(T)误(F)
