Organise information from the passage and complete the diagram.
Modern research is showing that plants can __________________________
communicate with each other

When another plant detects the chemicals, it starts to _________
__________________
_____________.
from the
leaves
release its
own, different
chemicals
Using sound
Some plants make noises _______________.
A chili plant can ____________________________________________.
Some trees make ____________________________________________________________________________.
with their roots
tell if a neighbouring plant is helpful, or unfriendly
clicking noises when there is not enough water, indicating drought is arriving
Using the “wood wide web”
This fungal network links ______________________
______________________.
Plants can _______
_____________________________ with each other.
Plants can _____________
_____________________ ______________to attack other plants.
the roots of different plants to each other
share
information and even food
steal food from each other, or spread poisons
Maybe one day we will be able to “talk” with plants.
1. What figure of speech is being used when the plants are described as calling for help What is its function
Personification. It can make descriptions more vivid.
Personification means giving human characteristics to something that is not human. By using human characteristics to describe an object, animal or even a place, personification can make descriptions more vivid.
What is personification
Can you tell from the appearance of the word
拟人personification：把无生命的物体、自然现象、抽象概念等拟作人，赋予事物以人的思想、情感或行为方式，使其人格化。拟人化的写作手法可使文章更生动、形象、具体，让读者感到所描写的事物更活泼、亲近，增强文章的感染力。首先Secret Language将植物赋予人类的语言和思想，Secret则生动地描绘出植物之间交流的方式，奠定了全文的情感基调。
其次，talk、communicate、listen等词赋予植物以人的感官功能。share information and even food、send food to smaller pine trees、steal food from each other等生动地描绘出植物之间交流方式的多样化。
修辞手法之“拟人”
最后，... a warning, or a call for help: “I'm being attacked! ” 、helpful, or unfriendly、its own version of “cybercrime”等栩栩如生地向读者勾勒出一副画面——植物在受到危害、攻击时的反击。作者虽没有具体描写植物在形态上的应激反应，但这样的描述使读者更容易将植物的行为与人类的日常生活相联系，便于理解。
由此可见，写作时用好拟人手法，常常能够达到生动形象、富有趣味的效果。
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.
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.
Give a talk about communication between living things.
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.
What other ways can you think of
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.
Check list

1. With us long believing that talking plants are fantasy, new research has revealed something amazing: it appears that plants can communicate after all.
We could also say
While we have believed for a long time that talking plants are unreal, new research has found out something amazing: it seems that plants can talk to each other after all.
2. When another bean plant detects the chemicals from its injured neighbour, it starts to release its own, different chemicals.
detect v. to notice or discover something, especially something that is not easy to see, hear etc.

连接(两个或两个以上的物、人或地点)
eg The new bridge will link the island to the mainland.

eg Researchers have found that there is a direct link between the increase in food eaten outside the home and the rise in weight problems. (翻译)
