Starting out & Understanding ideas
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
Master animal-related vocabulary by reading magazine pages and understanding basic information about rare animals. Extract key information of the passage. Grasp the main idea of narrative texts, analyze Darwin’s discovery journey in chronological order, and understand the structure and language features of narrative writing.
Cultivate the awareness of the cultural significance of biodiversity and environmental protection, recognizing the value of rare animals and plants in ecological and scientific contexts, and understand the cultural importance of scientific exploration in promoting human understanding of nature.
Develop your logical thinking by organizing Darwin’s discovery journey in the order of event development, enhancing the ability to analyze narrative structures and chronological sequences.
Adopt effective reading strategies to independently acquire information about scientific topics, improving autonomous learning ability. And use language knowledge to discuss and explore scientific themes actively.

PART. 02
Do you like animals Do you recognize these animals
The Komodo dragon 科莫多巨蜥
The Komodo dragon is the largest lizard in the world. It can grow to three metres in length and can weigh about 135 kilograms. Despite its size and weight, it can run for short distances at up to 20 kilometres per hour.
The Duck-billed platypus 鸭嘴兽
The duck-billed platypus is a small egg-laying mammal(up to 60 cm in length) found only in Eastern Australia including Tasmania. As its name suggests, it has a mouth that looks like a duck’s bill, while its thick fur and flat tail are similar to those of a beaver.
Nautilus 鹦鹉螺
As one of the oldest sea animals in the world, the nautilus has hardly changed in about 500million years, and that is why it is often given the name “living fossil”.
Look at the page from a science magazine and answer the questions.
1. What do you know about these animals What makes them special
They are all species that exist thousands of years on earth. They are old and rare (unusual).
2. What other similar animals do you know about Share your knowledge with the class.

1. How can seeds travel How can this benefit plants

Read the passage and talk about your understanding of the title.
A Journey of Discovery
Read the passage and talk about your understanding of the title.
A Journey of Discovery
Most commonly, people believe that a journey means a trip from one place to another, especially over a long distance and literarily a journey refers to the process by which something gradually changes and develops. The title may indicate that Darwin’s research work leading to his discovery of evolution and the origin of species took quite a long time and great efforts, determination and courage to achieve.
Charles Darwin and his Theory of Evolution
Charles Darwin (1809-1882) was an English geologist and naturalist. In his famous book On the Origin of Species, Darwin proposed the theory that organisms (individual life forms) evolve extremely slowly. He stated that the organisms that were better suited to their environments would survive and pass on their favourable characteristics to the next generation, while the less suitable organisms would gradually die out. He called this process “natural selection”.
Darwin’s Theory of Evolution is one of the basic foundations of modern science. It shows that plants and animals can change over time. The changes are usually small and difficult to detect, but they add up over many generations and can result in new species.
Choose the main idea of the passage and give your reasons.
Darwin’s interest in various living things made him a great naturalist.
Darwin’s journey on the Beagle inspired his Theory of Evolution.
Darwin went on a journey to confirm his theory that humans had evolved over time.
Read the passage and match each paragraph with its main idea.

Para. 7
Organise information from the passage and complete the diagram.
1. On his journey
Darwin studied various living things in their natural environments and samples of the plants and animals he had collected.
He noticed that some species of animals were very similar to each other.
2. Generate ideas
Darwin asked the questions:
How did different species come to exist
Maybe animals evolved as they adapted to their changing environments
Organise information from the passage and complete the diagram.
3. Look for more evidence
On the Galápagos Islands:
He noticed that there was a difference between the finches on each of the islands.
It seemed the beaks had evolved according to what food was available on that particular island.
4. Develop ideas
Darwin suspected that the finches had evolved from a common ancestor, which had arrived on the islands a long time before and it had slowly evolved into many new species.
Organise information from the passage and complete the diagram.
5. Propose a theory
The Theory of Evolution: living things, including humans, had evolved from lower forms of life.
Now discuss why Darwin did not publish his Theory of Evolution until 1859, about twenty years after his discovery. Do further research if necessary.
Choose the best answer for the following questions according to the passage.
1. Why didn’t the captain of the Beagle think Darwin was the best choice
A. Because Darwin wasn’t admitted to a university.

C. Different species lived in different environment.
D. The more complicated the species were, the more time it took.
4. How did people feel Darwin’s theory
A. Astonished. B. Excited.
C. Satisfied. D. Interested.
Think & share
1. Why were many people “shocked” by Darwin’s theory
At that time, people believed that all species had appeared on Earth at the same time and had not changed since, but Darwin’s theory proposed that living things, including humans, had evolved from lower forms of life, which, as a result, shocked many people.
What kind of person was Darwin according to the passage
