     As civilization proceeds in the direction of technology, it passes the point of supplying all the basic

essentials of life-food, shelter, clothes and warmth. Then we are faced with a choice between using

technology to provide and fulfill needs which have now been regarded as unnecessary or, on the other

hand, using technology to reduce the number of hours of work which a man must do in order to earn a

given standard of living. In other words, we either raise our standard of living above that necessary for

comfort and happiness or we leave it at this level and work shorter hours.

     I shall take it for granted that mankind has, by that time, chosen the latter alternative. Men will be

working shorter and shorter hours in their paid employment. It follows that the housewife will also expect

to be able to have more leisure in her life without lowering her standard of living. It also follows that

human domestic servants will have completely ceased to exist. Yet the great majority of the housewives

will wish to be relieved completely from the routine operations of the home such as scrubbing the floors

or the bath of the cooker, or washing the clothes or washing up, or dusting or sweeping, or making beds.

      By far the most logical step to relieve the housewife of routine is to provide a robot which can be

trained to the requirements of a particular home and can be programmed to carry out half a dozen or

more standard operations, when switched by the housewife.

A. the choice of providing and fulfilling our needs

B. the choice of using technology

C. the choice of earning a standard of living

D. a choice between using technology to provide and fulfill needs to reduce the number of working hours

3. What alternative will mankind have chosen in future?

A. To leave our standard of living at this level and work shorter hours.

B. To raise our standard of living.

C. To fulfill needs which have been regarded as unnecessary.

D. To lower our standard of living and work shorter hours.

某化学兴趣小组对一包干燥的红色粉末组成进行探究.请你参与并回答有关问题.

教师提醒:它由Cu、Fe203二种固体中的一种或两种组成.

提出猜想:红色粉末可能的组成有:①只有Cu;②只有Fe203;③是Cu、Fe203

混合物

资料获悉:Cu在FeCl3溶液中发生反应:2FeCl3+Cu═2FeCl2+CuCl2

实验探究

(1)甲同学取少量红色粉末于试管中,滴加足量稀盐酸,振荡后观察,发现固体全部溶解.甲同学认为可以排除猜想中的①和③,而乙同学认为只能排除猜想①,你认为______的观点正确(填“甲”或“乙”).

(2)丙同学为进一步确定红色粉末的组成,称取该粉末5.0g装入硬质玻璃管中,按如图在通风橱中进行实验.开始时缓缓通入C0气体,过一段时间后再加热使其充分反应.待反应完全后,停止加热,仍继续通C0气体直至玻璃管冷却.反应前后称量相关装置和物质的总质量,其数据如下表:

反应前反应后
Ⅰ组玻璃管和红色粉末的总质量为37.3g玻璃管和固体物质的总质量为36.1g
Ⅱ组洗气瓶和所盛溶液的总质量为180.0g冼气瓶和瓶中物质的总质量为183.1g
交流讨论

①在装置A中先通C0气体的作用是______.

②应该选择______组的实验数据计冀来确定红色粉末的组成.

最终计算结果表明:该红色粉末的组成是猜想中的第______组(填序号).

③写出A装置中发生反应的化学方程式______;实验中观察到A装置中的现象为______.

反思评价:丁同学指出:从环保角度,上图装置有严重不足之处.你认为应该如何改进?______.
