Unit 3 A healthy life language points课时作业

Ⅰ.阅读理解

Robots and computers could soon be having meaningful conversations and even arguments with humans.A new research project will develop systems that allow men and machines to debate decisions.It opens up the possibility of human operators discussing action plans with robots and，if necessary，ordering them to break rules.

For their part，the computers would be able to argue in favour of decisions or inform their operators that certain tasks are impossible.Early versions of the software could be available in just three years.Lead researcher Dr.Wamberto Vasconcelos，from the University of Aberdeen，said the aim is to increase human trust in intelligent technology.

Talking computers with the ability to converse with humans have long been a support of science fiction.Examples include Hal，the deadpan­voiced computer in the film 2001：A Space Odyssey，which goes mad and sets out to murder the crew of a spaceship.

The system Dr.Vasconcelos is developing will communicate with words on a computer screen rather than speech.Potentially it can be used to accomplish unmanned robot missions to planets or the deep sea，defense systems and exploring the enemy environments such as the nuclear base.

"Ultimately，this conversation is to ensure that the system is one the human is comfortable with，but the dialogue will be a two­way thing.The supervisor might not like a particular solution but the computer might say 'Sorry，this is all I can do.'"

Conversing with robots would actually make humans more responsible，since failures could not conveniently be blamed on computer error，Dr.Vasconcelos added，"With power also comes responsibility.All these dialogues are going to be recorded，so there is a name to blame if something goes wrong.It's a good side effect."

【语篇解读】　这是一篇说明文。人机对话是梦想还是现实？科学技术是把双刃剑，给人类带来便利的同时，也对人的责任感提出了更高的要求。
