The second is the kind of flower within that group and is like a given/personal name. Before Linnaeis there was no way of finding out whether a plan
21、t 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,Robert Briggs (RB) is talking to Zhang Wei
22、(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 biology teacher told me th
23、at 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 biological na
24、me. 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 centre of konigsberg is an island and as it passes the island the river breaks into two
29、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 Rea
30、ding task. It is a Euler path for Figure 3.,A MATHEMATICIANS PROBLEM John Smith (JS) is talking to Zhao Yang (ZY) about a mathematician who interests him. Part 1 JS: 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
31、the eighteenth century. 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
32、 and the terms sine and cosine. ZY: 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 2 ZY: What were his achievements? JS: He introduced a new branch of mathematics called topology. It helps you understan
33、d things by using diagrams. The subway map is a 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
34、a river running through it.. The centre is an island. As the 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.,
