It means that his flower has already been identified and has a name.
He would know by checking his lily against other lilies in the specialist book. If his lily is different (for example in the number of petals or stamens) it will be a new species.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.
Before Linnaeis 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 FLOWERRobert Briggs (RB) is talking to Zhang Wei (ZW) about a new kind of lily he has found.ZW: Hello Robert. What’s that book you’re carrying?
RB: A book that helps you identify a flower.
ZW: I see. Why do you want that?
RB: Well, I’ve found this lily. It looks different to me. So I want to find out if it’s new or not. Our biology teacher told me that If it’s already known, I’d 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 It’s in the book?
RB: It means that somebody else has found it and named it. Then I’ll know its 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, the colour of an autumn sunset.. Together you get the flower’s 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 nobody could tell if a plant was new, as there was no way of checking. There’re so many plants, you see!
ZW: Yes, I appreciate that! So his system is still used?
RB: Indeed it is. If my flower isn’t in this book, I’ll know that I’ve found a new kind of lily.
ZW: That’s great! Can I come and help you? This research sounds fun.
RB: Yes, and if I’m lucky…(fading out)Answer key for Exercise 1:

Tick all symbols except angle.Listening Task on page 44Answer key for Exercise 4:Why Euler is considered to be a great mathematicianintroduced many new symbols into maths
wrote more books than anyone before or since
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 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 task. It is a Euler path for Figure 3.A MATHEMATICIAN’S PROBLEM
John Smith (JS) is talking to Zhao Yang (ZY) about a mathematician who interests him.
Part 1
JS: Do you know that we’ve been studying Euler in maths?
ZY: Who is he? I’ve never heard of him.
JS: Well, he was a famous mathematician in the eighteenth century. He revised all the pure mathematics that was know in his day.
ZY: That probably wasn’t very much.JS: You’re 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: 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 understand things by using diagrams. The subway map is a good example. It doesn’t 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 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 it’s not easy as it looks.
