分析
该部分着眼于让学生结合科学技术的发展现实，了解机器人与人工智能在现代生活中的运用，探讨在未来的数十年间，机器人和人工智能与人类关系的发展方向。听力内容是电台播出的一档科幻作品专家的访谈节目，学生需要通过听力了解未来学家对机器人发展的客观看法，了解、分析著名的机器人三定律，在和同学探讨之后，发表个人观点。从语言运用和对话交际策略来看，听力内容中主持人运用了转换话题的技巧，提示学生在语言分析与运用时能注意关注、理解话语标记的不同功能，提升逻辑思维和语言的理解与表达能力。

1.shw sme dynamic pictures f rbts.
2.Brainstrming:
What can rbts d In ur daily life?
While-class
Activity 1
lk at the pictures and discuss the questins in pairs.
What jbs are these rbts ding? what are the prs and cns f rbts ding these jbs?
1）Tw rbts are serving fd at a cafe.
Prns:Maybe the service is cheaper and faster.
Cns:The custms will have cmmunicatins difficulties, and there is n human tuch.
2）A rbt is playing the pain.

in a cntest and have n desire t win r lse,s
there is n emtinal cntent t the match and
there is n physical skill r talent invlved.
2. what kind f rbts r AI develpments d yu hpe fr?
Varius answers...
Students lk at sme dynamic pictures f rbts.
The students discuss the questins..
T aruse students’ interest .
Serve as a warm-up fr the activities which fllw intrducing key vcabulary and cncepts.
Activity 2
Listen t an interview and put these statements in the crrect rder.
The hst intrduces the guest, a sci-fi expert.
The expert has rbts in his hme.
As rbts becme mre intelligent,they may als becme mre dangerus.
The hst mentins Asimv's Three Laws f Rbtics.
The expert says rbts will have ccupatins such as teaching and nursing.
The line between humans and rbts will be mre blurred in the future.
The hst asks abut benefits and prblems.
The hst asks if there are rbts in the expert's hme.
In sci-fi stries, rbts ften becme superir and take ver.

Students listen t an interview.
Practise listening fr gist using a true-t-life interview in natural English.
Activity 3
Listen t the interview again and write dwn the discurse markers that yu hear. Make a nte f hw each discurse marker is used in the interview. Then cmpare yur answers with a partner.
(Discurse markers are used t rganise a text by making sequence,cntrast,pinin,
purpse,and s n. Listening fr discurse markers can help yu understand a text mre easily.)
Regular Discurse Markers
Students listen t an interview again.
Practise listening fr discurse markers In the interview.
Activity 4
In grups,discuss what the expert thinks f the questins and exchange yur wn views.
What d yu knw abut rbt technlgy? What can rbts d ?
Rbts technlgy has its cns and prs.It can bring great cnvenience t human beings tgether with sme scientific r mral prblems.A rbt is a machine that can d a task accrding t cmputer prgrammes r thrugh the use f sme kind f cntrls.
2.What benefit d yu think rbt r AI will bring? D yu think they will cause prblems as well?
The main benefits are that they can d sme kinds f wrk mre quickly，better，and cheaper than humans，and that they can take the place f humans when n humans are available r when humans can nt d the wrk. Hwever，they can cause prblems,First,what happens if they n lnger serve peple r stp fllwing rders? Secnd,there is the pssibility that at sme pint we will have difficulty determining what cnstitutes a living being and what cnstitutes a machine.
3.D yu knw anything abut Isaac Asimv and his famus Three Laws f Rbts?what d yu think f these laws?
Yes,I d.Isaac Asimv intrduced them int mst f his science fictin writings t shw that rbts culd
be prevented frm harming us r ur wrld.They are nt actual scientific laws， but rather guidelines fr their
human prgrammers t fllw t keep ur wrld safe.At first glance，the rules seem lgical and reasnable，but they als seem ut dated.
Changing the tpic
Oh， by the way， ... Oh， I remember，
... In early frgt!... That reminds me f...
What I meant t tell/ask yu ，
Culd I change the subject?
but(perhaps) that’s beside the pint.
The next item n the agenda is...
I think we ught t mve n t... Oh，
there was smething I meant t tell yu.
On the ne the ther hand...
Example:
A：Oh, by the way, I saw a prgramme abut rbt dctrs last night.It was very interesting.D yu think rbts will d mre f these imprtant jbs in the future?
B：Certainly.They will prbably d mst f ur labur fr us.
C：Maybe，but that's beside the pint. In my pinin, rbts are dangerus!They are much strnger than we are and may be superir t us in the future.
A :I think we ught t mve n t the tpic f rbt technlgy. I knw the idea f it has been arund frever.The ancient Greeks and Chinese bth made clever devices that weren't much different than sme f the rbts we have tday.
B：Yes, but the mdern idea f intelligent rbts that lk like humans is nly abut 100 years ld.
C:I think we had better mve n t what rbts can d.Let's are simple repetitive tasks like factry wrk and husewrk.
A:Yes, and I think there will be mre cmplex jbs in the future like in healthcare, educatin, r entertainment.
B:Oh, there is smething else I meant t ask yu—des anyne knw wh even came up with the wrd“rbt”?
C:But that's beside the pint. I think we ught t mve n t the benefits and dangers f A I t humans and ur sciety.
A:Oh, In early frgt why Asimv's writing was s imprtant—he created the Three Laws f Rbtics. Law l,rbts can't injure humans r allw
them t cme t harm; Law 2, a rbt must bey any rder a human
gives it as lng as it desn't cnflict with the first law; and Law 3,a rbt
must prtect itself as lng as the act f ding s desn't break the first r secnd law……
