[背景资料]

某写字楼工程,地下1层,地上15层,框架一剪力墙结构。首层中厅高12m,施工单位的项目部编制的模板支架施工方案是满堂扣件式钢管脚手架,方案由项目部技术负责人审批后实施。施工中,某工人在中厅高空搭设脚手架时随手将扳手放在脚手架上,脚手架受振动后扳手从上面滑落,顺着楼板预留洞口(平面尺寸0.25m×0.50m)砸到在地下室施工的王姓工人头部。由于王姓工人认为在室内的楼板下作业没有危险,故没有戴安全帽,被砸成重伤。

何谓“三宝”和“四口”本例的预留洞口应如何防护?

     The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and ease us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be

less sure. Quite soon, in only l0 or 20 years, perhaps, we will be able to assemble a machine as complex

as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading

in the right software or by altering the architecture but that too will happen.

     I think it certain that in decades, not centuries, machines of silicon(硅) will arise first to rival and then

exceed(超越) their human ancestors. Once they exceed us they will be capable of their own design in a

real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And

we will no longer be able to claim ourselves to be the finest intelligence in the known universe.

     As the intelligence of robots increases to match that of humans and as their cost declines through

economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction

of a vast, man-created world in space, home to thousands or millions of people, will be within our power.

1. In what way can we make a machine intelligent?

A. By making it work in such environments as deserts, oceans or space.

B. By working hard for 10 or 20 years.

C. By either properly programming it or changing its structure.

D. By reproducing it.

2. What does the writer think about machines with human-like ability?

A. He believes they will be useful to human beings.

B. He believes that they will control us in the future.

C. He is not quite sure in what way they may influence us.

D. He doesn't consider the construction of such machines possible.

3. The underlined word"carbon"in Para. 2 stands for         .

A. intelligent robots          

B. a chemical element       

C. an organic substance        

D. human beings

4. A robot can be used to expand our frontiers when         .

A. its intelligence and cost are beyond question

B. it is able to bear the rough environment

C. it is made as complex as the human brain

D. its architecture is different from that of the present ones

5. It can be inferred from the passage that          .

A. after the installation of a great number of cells and connections, robots will be capable of

    self-reproduction.

B. with the rapid development of technology, people have come to realize the possibility of making a

     machine with human-like ability

C. once we make a machine as complex as the human brain. it will possess intelligence

D. robots will have control of the vast, man-made world in space
