5、his lily is a new species?3 Why do plants all have two names?4 What was the serious problem for biology that Linnaeus solved?,1 If Robert Briggs finds the flower in the book, what does that mean?,It means that his flower has already been identified and has a name.,2 How would he knows if his lily is
6、 a new species?,He would know by checking his lily against other lilies in the specialist book.

The first is the group of flowers they belong to and is like the family n
7、ame. The second is the kind of flower within that group and is like a given / personal name.,4 What was the serious problem for biology that Linnaeus solved?,Before Linnaeus there was no way of finding out whether a plant was new or not. This causes problems becausedifferent scientists claimed that
8、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 A FLOWERRobert Briggs (RB) is talking to Zhang Wei (ZW) about a new kind of lily he has found.,Listening text,ZW: Hello Robert. Wha
9、ts that book youre carrying?RB: A book that helps you identify a flower.ZW: I see. Why do you want that?RB: 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 that if its already known, Id find it in this book.,ZW: Wow! So you think yo
10、u 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 name.ZW: What do you mean by the biological name?,RB: Actually like us a fl
11、ower 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 flowers name, which is Ros
12、e 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 ch
13、ecking. 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 sounds fun.RB: Yes, and if Im lucky (fading out),1 Thi
