A By’s Best Friend

In the future
Mr Andersn，Jimmy’s father
Mrs Andersn，Jimmy’s mther
Rbutt，a mechanical dg， Jimmy’s pet
Plt Jimmy’s parents get a dg frm Earth. They want t give it t Jimmy as a pet. attitudes twards Rbutt ·Parents：___________________________________________________·Jimmy：___________________________________________________
Jimmy already has a rbt pet named Rbutt. His parents think it wuld be gd fr Jimmy t have a real dg，and that he wuld like it. They want t send Rbutt t anther family. T his parents’ surprise，Jimmy refuses t accept the real dg，because he lves Rbutt and he believes Rbutt lves him t. Fr Jimmy，Rbutt is nt just a mechanical dg，but a real friend.
They think Rbutt is a mechanical imitatin f a real dg.
He lves Rbutt and treats him like a real dg.
Nw talk abut yur attitudes twards the stry.
What are the similarities and differences between Rbutt and a real dg?
Similarities:Bth are able t respnd t rders given by human beings. Bth can utrace human beings. Bth can guide and prtect human beings.
Differences: They have different appearances.A real dg is a living creature, while Rbutt is a machine.A real dg lves human beings as a result f its nature, while Rbutt is just adjusted t act as thugh it lves human beings.
Is there any freshadwing f Jimmy’s final decisin? Find clues in the reading passage.
Yes，there is. At the beginning f the stry，we knw Jimmy has never seen a real dg. It als seems that he spends a lt f time with Rbutt. Jimmy plays with Rbutt enthusiastically, shuting“Cme n, Rbutt.”In the middle f the passage，we are tld that “Jimmy culdn’t g wrng while Rbutt was arund”， indicating that Rbutt prtects Jimmy well.
What ther sci-fi nvels abut rbts can yu think f? Share ne with the class.
One pssible answer: There is ne bk named I, Rbt, which is als written by Isaac Asimv. In my pinin, this bk can be regarded as ne f the best sci-fi nvels abut rbts. Anyne interested in sci-fi nvels shuldn’t miss it.
The tw reading passages in this unit shw us different aspects f technlgy in the future. Which f these d yu mst expect t encunter in yur lifetime?
I expect t encunter ne rbt dg such as Rbutt. I think such kind f dg is f much benefit and help t mankind. Fr example the“rbtic guide dg”will help supprt visually impaired peple wh are unable t have a real animal.
Give a talk n whether it is pssible t have a real friendship with a rbt.
Answer the questins t help t frm yur pint f view. Why d Jimmy and his parents have different feelings twards Rbutt?
Because Jimmy was brn n the Mn，he has never seen a real dg. He has been getting alng well with Rbutt，and thus has develped an affectin fr him. He cannt figure ut why a real dg is better than a mechanical dg，despite his father’s explanatin. While Jimmy’s parents have seen real dgs befre they left Earth. They knw what real dgs lk like. They think Rbutt is just a machine.
Answer the questins t help t frm yur pint f view. If yu were Jimmy, which ne wuld yu chse, Rbutt r a real dg?
If I were Jimmy，I wuld chse t wn a real dg，because I need real cmfrt and genuine lve and lyalty frm my pet.
Organise the main pints yu wuld like t cver and cmplete the table.
It is pssible.
We enter the era f scial rbtics.
Like the clse relatinship between Jimmy and Rbutt.
We will all be having relatinships with rbts.
Give yur talk t the class.

Carlyn had a lng cmmute t the prisn, even by aircar. When she arrived, everything seemed nrmal, except fr a rbt lying at the frnt gate, mtinless. It’s an ld mdel, she thught. They brke dwn nw and again. She passed thrugh the gate, nting that everything else was apparently in rder. But just as she clsed her ffice dr behind her, a lud alarm sunded. Carlyn’s bld frze. She had nly ever heard that sund during drills. It can’t be! She thught. A general systems failure! She lked ut f the reinfrced glass f her ffice windw int the prisn belw. Sure enugh, the rbts were ut f cntrl. Mst had stpped mving at all. Sme spun aimlessly arund and arund.
But thers were randmly perating things, including the cell gates, and she culd see prisners rushing ut t freedm. “Grab the rbts’ weapns and run!” shuted the prisners. Carlyn pened her bag and reached fr her emergency call device. Her heart sank as she realised she had left it at hme. I need t call in the plice, she thught. But hw? Withut the device, she culdn’t cmmunicate. Nthing in the prisn wuld wrk prperly nw. There was a vice behind her. “Lking fr ne f these?” Carlyn gasped. “Julius!” There was her secnd-in-cmmand, hlding an emergency caller in his hand. “What are yu ding in my ffice?”
“It shuld be my ffice!” snarled Julius. “I’ve wrked here fr frty years ... and the City Cmmissiners gave yu the jb as prisn gvernr! But nw yu’ll pay. Yu’ll all pay! I can make every rbt in every prisn in the city g crazy. The prisners will escape, and the city will burn!” Then the dr burst pen, and the rm was suddenly flded with rit plice. And there was ... Tdd! “I tk the aircar ver here t bring yu this,” he said quietly, winking as he pushed the emergency call device secretly int her hands. “I culd see there was truble, s I activated it t call in the plice.”
“It was Julius,” said Carlyn, watching the plice bundle Julius ut f the dr. “He’s gne mad.” “Sure,” said Tdd. “But nw we knw hw easy it is t cause a mass rbt breakdwn. Yu’ll have t write a reprt. Make sme recmmendatins t upgrade the rbts.” “I knw.” Carlyn slid frm Tdd’s hug and walked twards the dr. She culd see the plice runding up the prisners. “But right nw, I’ve gt a prisn t run.”
