     We are already familiar with computers-computers work for us at home, in offices and in factories.

But it is also true that many children today are using computers at schools before they can write. What

does this mean for the future? Are these children lucky or not?

     Many people who do not know about computers think of them as machines that children play with.

They worry that children do not learn from experience but just from pressing a button and that this is not

good for them. They think that children are growing not knowing about the real world.    

     But people who understand more about computers say that computers can be very good for children.

A computer can help them to learn about the real world more quickly, to learn what they want to 1earn

and think for themselves. And for the future, don't we need people who can think clearly, who know

how to get information quickly and use it well? What do you think?

现有热敏电阻、电炉丝、电源、电磁继电器、滑动变阻器、开关和导线若干．如图所示，试设计一个温控电路．要求温度低于某一温度时，电炉丝自动通电供热，超过某一温度时，又可以自动断电.工作过程：闭合S当温度低于设计值时热敏电阻阻值大，通过电磁继电器电流不能使它工作，K接通电炉丝加热．当温度达到设计值时，热敏电阻减小到某值，通过电磁继电器的电流达到工作电流，K断开，电炉丝断电，停止供热．当温度低于设计值，又重复前述过程．试根据所给器材按要求连接电路。

选择比较交易案例时，应符合的要求有( )。

A．交易案例为正常交易

B．与待估土地大小相近

C．与待估土地用途应相同

D．交易时间与待估土地的估价期日应接近

E．与待估土地的交易类型不同

A．UDP协议效率较高，用它实现网络管理不会太多地增加大网络负载

B．TCP协议不可靠，SNMP报文容易丢失

C．UDP协议需要连接，TCP协议不需要连接

D．UDP协议可靠，所以传输SNMP报文更容易
