ListeningUnit 1 WorkbookRobert Briggs is very interested in biology and especially in the study of plants. Today he is telling his friend Zhang Wei some exciting news. Read the questions before you listen to the tape. This will help you to understand the information.1. Before you listen to the tape discuss with your partner how you would find out the name of a flower. This is about a man who wants to name a flower. This is about a man who finds a flower and wants to own it. This is about a man who finds a flower and wants to know if it is a new species of flower.Listen to the tape again and try to complete the following passage.To find the name of an unknown flower, first you should ask your _ teacher to help you. He / She will look in a special _written by Carl Linnaeus. He lived in _ from _ to _ . He was very important because he solved a _ problem for biology.Listen to the tape and tell what the listening passage is about.biolog y bookSweden 17101778 seriousListen to the tape a third time and answer these questions. 1. If Robert Briggs finds the flower in the book, what does that mean? It means his flower has already been identified and has a name. 2. How would he knows if his lily is a new species? By checking it against other lilies in the specialist book. 3. Why do plants all have two names? Because the first is like the family name, and the second is like a given / personal name. 4. What was the serious problem for biology that Linnaeus solved? His system was easy to discover whether a plant was new or not and 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. 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: 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 you 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 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 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 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 sounds fun. RB: Yes, and if Im lucky (fading out)Using words and expressions 1. This is a report on living conditions in England in the 19th century.
