14、,Sample conversation:A:What do you want to do when you grow up?B:I want to build robots.I will have to do a physics and mathematics degree in China.After that I hope to go abroad to Reading University in England where you can study all about robots.There is a special cybernetics(控制论)department there

15、.A:What personality will be needed for that job?B:I think I need to be patient for my ideas which will take a long time to develop.I also need to be creative enough to have good ideas.A:What experience will be most useful to you?B:I think technology and engineering projects.I hope to work in a facto

17、hink designing robots sounds fun.Answer key for Exercise 1:Possible answers include:Go to your teacherGo to a natural museum and speak to a specialistLook it up in a flower bookListeningon page 41Answer key for Exercise 2:The correct answer is C.Summary A is not correct because it does not give enou

18、gh information.Summary B is inaccurate.Answer key for Exercise 3:Biology,book,Sweden,1707,1778,seriousAnswer key for Exercise 4:1.It means that his flower has already been identified and has a name.2.He would know by checking his lily against other lilies in the specialist book.If his lily is differ

19、ent(for example in the number of petals or stamens)it will be a new species.3.All plants have two names just like people.The first is the group of flowers they belong to and is like the family name.The second is the kind of flower within that group and is like a given/personal name.4.Before Linnaeis

20、 there was no way of finding out whether a plant was new or not.This caused problems because different scientists claimed that they had found and named flowers first.After he organized his system it was easy to discover whether a plant was new or not and so who had the right to name it.NAMING FLOWER

21、Robert Briggs(RB)is talking to Zhang Wei(ZW)about a new kind of lily he has found.ZW:Hello Robert.Whats that book youre carrying?RB:A book that helps you identify a flower.ZW:I see.Why do you want that?RB:Well,Ive found this lily.It looks different to me.So I want to find out if its new or not.Our b

22、iology teacher told me that If its already known,Id find it in this book.ZW:Wow!So you think may have found a new lily?RB:I hope so,but I have to do some research first to find out for sure.ZW:What happens if Its in the book?RB:It means that somebody else has found it and named it.Then Ill know its

23、biological name.ZW:What do you mean by the biological name?RB:Actually like us a flower has two names.The first is the group of flowers it belongs to-like a family name.A rose is one such group.The second is the kind of flower-like a given name.It may describe what the rose looks like;for example,th

24、e colour of an autumn sunset.Together you get the flowers name,which is Rose Autumn Sunset.ZW:Gosh!Who made that system?RB:A great scientist called Carl Linnaeus.He lived in Sweden from 1707 to 1778.ZW:So long ago!RB:Yes,and he solved a very serious problem for biology.ZW:What was that?RB:Before him

25、 nobody could tell if a plant was new,as there was no way of checking.Therere so many plants,you see!ZW:Yes,I appreciate that!So his system is still used?RB:Indeed it is.If my flower isnt in this book,Ill know that Ive found a new kind of lily.ZW:Thats great!Can I come and help you?This research sou

26、nds fun.RB:Yes,and if Im lucky(fading out)Answer key for Exercise 1:Students will give their own answers which may very.Answer key for Exercise 3:Tick all symbols except angle.Listening Task on page 44Answer key for Exercise 4:eulers new branch of mathematicstopologyWhy Euler is considered to be a g

27、reat mathematician1.introduced many new symbols into maths2.wrote more books than anyone before or since3.discovered a new branch of mathematicsSuggest answers to Exercise 5:It had a river running through it.The centre of konigsberg is an island and as it passes the island the river breaks into two

28、parts.Seven bridges were built so that the people of the city could get from one part to another.The people wondered if you could walk around the city so that you would cross each bridge only once.Suggested answers to Exercise 6:There is no Euler path for this figure.Look at Figure 4 in the Reading

29、task.It is a Euler path for Figure 3.A MATHEMATICIANS PROBLEMJohn Smith(JS)is talking to Zhao Yang(ZY)about a mathematician who interests him.Part 1JS:Do you know that weve been studying Euler in maths?ZY:Who is he?Ive never heard of him.JS:Well,he was a famous mathematician in the eighteenth centur

30、y.He revised all the pure mathematics that was know in his day.ZY:That probably wasnt very much.JS:Youre wrong there.He wrote more than any other mathematician before or since.ZY:Really!Well,what did he do?JS:He introduced a lot of symbols into mathematics such as pi and the terms sine and cosine.ZY

31、:Wow!JS:And he did half of this work when he was blind.ZY:How did he do that?JS:He told his ideas to someone else who wrote them down.Part 2ZY:What were his achievements?JS:He introduced a new branch of mathematics called topology.It helps you understand things by using diagrams.The subway map is a

32、good example.It doesnt tell you distances but it shows how stations connect together.ZY:How did he start topology?JS:Well,in 1735 he was inspired by a problem in the city of Konigsberg where he lived.Look at the map in your book.Konigsberg had a river running through it.The centre is an island.As th

33、e river passes the island.It breaks into two parts.Seven bridges were built over the river.Euler wondered if you could walk around the city so that you cross each bridge only once.ZY:Let me try that.It sounds quite simple to me.JS:Let me try that.It sounds quite simple to me.JS:Try,but its not easy as it looks.
