Learning Objectives
PART. 01
Understand the daily study and life of British middle school students by watching videos. Based on your own daily study and life, compare the study and life in Chinese and British schools, and find out the similarities and differences between the two. Talk about your first impression of high school life, and have a preliminary perception of the study and life in the senior high school stage.
Learning Objectives
Understand the text content, master theme-related key vocabulary, and clearly describe various communication methods between natural plants introduced in the text. Master the stylistic features of descriptive explanatory texts, clarify the theme based on text structure analysis.
Understand the important significance of “harmonious coexistence between humans and nature,” appreciating global efforts in conveying ecological concepts through art and science.
Develop the analytical thinking by analyzing the structure of descriptive explanatory texts and categorizing plant communication methods, enhancing logical reasoning and information-summarizing abilities.
Adopt effective learning strategies to independently acquire knowledge about plant communication and text styles, improving autonomous learning skills. Expand learning through recommending documentaries, using multiple channels to gather information about human-nature relationships.

Personification. It can make descriptions more vivid.
Think & share
2. What does “wood wide web” mean
“Wood wide web” means an amazing system of communication that can link nearly every plant in a forest. It is linked underground by fungi and this fungal network links the roots of different plants to each other. Using the wood wide web, plants can share information and even food with each other.
Think & share
3. What do you think are the benefits of studying plant communication
4. What discoveries are described in the two reading passages in this unit and what do their meanings have in common
Passage 1 reveals the discovery of evolution and Passage 2 reveals the discovery of communication between plants. They all reflect that there are numerous secrets in nature that remain to be explored.
Work in groups. Give a talk about communication between living things.
What other ways can you think of
1. Read the passage again and talk about how plants communicate.
2. Think about and discuss the following ways of communication in the animal world.
Bees “dance” to signal to other bees that they have found food.
Ants communicate with each other through touch, chemical signals, moving their bodies and even using their legs to make sounds.
Work in groups. Give a talk about communication between living things.
3. Organise your ideas following the steps below.
Begin with what living things you have chosen to talk about.
Explain how they communicate and give examples.
Conclude by explaining what we have learnt from their behaviour.
4. Give a talk to the class about communication between living things.
Now talk about how well you contributed to your group discussion and help each other to make improvements.

An observational journal about the sunflower
1 June
Covered with 1-2 cm of moist soil, the sunflower seed takes a few days to come up after being planted. Water has been added regularly and the hard seed coat softens in the damp soil to allow the first root to pierce downwards and the first leaves to push to the soil surface.
6 July
The root continues to grow downwards. The single stem grows hollow and smooth, revealing large spade-shaped leaves from the growing tip. Gradually, the plant’s growing tip reveals the first hints of development of the flower bud. The plant stem becomes more woody.
26 July
About three weeks after the flower bud first becomes visible at the tip of the sunflower stem. It enlarges and begins to reveal a flattened disc. Over the course of one week, the yellow ray florets, and disc florets bloom across the core of the sunflower blossom. It is yellow, looking beautiful.
