Teaching Procedures:
Step I Warming up
1.Which plant and animal do you like best? Can you classify them into a system ?
2.Background: Carl Linnaeus (1707-1778) SwedishCarl Linnaeus is often called the Father of Taxonomy(分类学).He succeeded in classifying the plants and animals into a system that worked. His method was called “the sexual method” of classifying plants and animals.His system for naming, ranking, and classifying organisms is still in wide use today (with many changes). His ideas on classification have influenced generations of biologists during and after his own lifetime.
Step II. Listening P41
1. Choose which of the following statements most closely describes what
this listening passage is about . Explain why the others are wrong.
A. This is about a man who wants to name a flower.
B. This is about a man who finds a flower and wants to own it.
C. This is about a man who finds a flower and wants to know if it is a new species of flower.
2. Listen to the tape again and try to complete the following passage.
To find the name of the unknown flower, first you have to go to see a flower ________. He /She will look in a special ________ written by Carl Linnaeus. He lived in __________ from ________to __________. He was very important because he solved a serious problem for _________ . He saw all plants and animals produce _________________________. Some animals produce __________ but others lay _______ while plants ______________. He used these different ways of producing young to put plants and animals into _________. For example, the group called birds lay ________ to produce young and they all have ________. Linnaeus put the plants and animals into smaller groups or species. He gave each one two names. One is for the large group, for example _______ and one is for the species, for example _________. So a parrot would be ___________. He was the first person to successfully classify(分类)all plants and animals.
Step III. Talking P41
Imagine you are going to meet a specialist about a newly-found flower. Your partner will be the assistant for the flower specialist. You both need a description of the other so you can recognize each other when you meet. Now ring the assistant to sort out the necessary information. Pair work (Making a telephone call)
How will I recognize you?
What special features do you have?
What will you wear?
How will I know you?
What do you look like?
You can recognize me because…I’m tall/short, fat/thin, young/old with…My…looks a bit like…I have large /small ,brown/green eyes with…
Step IV. Play a game: Can you guess who he/she is?
One acts as an assistant, the other acts as the third person who wants to introduce a visitor (in the class) to the assistant. The whole class guess who the visitor is.

Step II. Play a Puzzle game
Can you go over it without missing any points or going over a line twice?
A A A
D D E
B C B C B C
Euler said, “If a figure has more than two odd points, you cannot go over it without lifting your pencil from the page or going over a line twice.”
Step III. Reading ( P45 ) Finding The Solution
1. Background
Leonhard Euler (1707-1783)
Born: 15 April 1707 in Basel, Switzerland
Died: 18 Sept 1783 in St Petersburg, Russia
Euler was a famous mathematician in the eighteenth century, he introduced a new branch of mathematics called topology. It is a form of geometry that help you understand things by turning them into diagrams.
2.Reading
