B, are there any words you don't understand? Default value:
(Mesozoic: As we all know, the earth has a history of 4.6 billion years. According to the age of strata, the age of the earth is divided into some units. People are used to dividing the whole 4.6 billion years into two big units. The era when creatures are invisible or hard to see is called Phanerozoic, and the era after a certain number of life can be seen is called Phanerozoic. Zhou Xia is divided into several generations. Generally speaking, there are five generations: Archean, Proterozoic, Paleozoic, Mesozoic and Cenozoic. Mesozoic belongs to the geological age, lasting about 1 100 million years. This generation is divided into Triassic, Jurassic and Cretaceous. The vertebrates in this period were mainly reptiles, dinosaurs flourished, and mammals and birds began to appear.
Fossil: refers to the remains, relics or remains of ancient creatures buried underground and turned into things like stones. Studying fossils can help us understand the evolution process of organisms and determine the age of strata.

Tens of millions of years later, its descendants have multiplied into huge families with different shapes: some run on two feet and some walk on four feet; Some are big, some are small; Some are fierce, others are docile. Some carnivorous dinosaurs gradually became smaller and looked more and more like birds. Their bones are hollow, their skulls are enlarged, their bodies are light, their movements are agile, their forelimbs are getting longer and longer, they can flap like the wings of birds, and they grow feathers without scales and nails. Some people jump and land in trees to avoid enemies or find food, and then they can fly. Kong Long runs and learns to fly on the ground. So a dinosaur evolved into a bird and flew into the blue sky.

Prompt students to develop reasonable imagination according to the table or text content, integrate their own knowledge about dinosaur evolution, and express it in an orderly way.
(4) Read the second paragraph of the text with emotion and learn the author's clear and orderly expression.
Summary: The evolution of dinosaurs is in chronological order. Firstly, the size, shape and walking mode of the first dinosaur 230 million years ago were described. Then, tens of millions of years later, introduce the reproduction, change and different forms of their descendants; A carnivorous dinosaur finally became a favorite because of the change of its posture, body surface and living habits, and flew into the blue sky.
Design intention: Respect students' learning needs, conform to students' reading psychology, guide students to go straight to the key points of learning, and understand the perceived language through self-reading since the enlightenment, group discussion, cooperation in filling out forms, personality expression and other forms, so as to realize the characteristics of expression and achieve the purpose of internalization and absorption.

What role does this passage play in the text?
(Transition: This passage arouses readers' strong interest in learning in the form of questions. Following the reader's reading ideas, the following passage naturally leads to the Mesozoic era, which reproduces the evolution of dinosaurs into birds. )
(2) Read independently and experience the characteristics of sentences.
Find out the sentences you think are vivid and read them. What's so good about it?
Remove the horizontal line from the sentence, read it out and tell me the difference. (Show courseware)
For example, ① "A branch of dinosaurs experienced a long evolution and finally became a bird soaring in the sky."
"A branch" refers to a branch of dinosaurs, not all; "Long evolution" refers to a long evolutionary process, not a sudden change.
② "Some dinosaurs closely related to birds should have feathers."
"Some" means not all dinosaurs; "Should" is a kind of speculation, which means you can't be sure until you find the evidence.
Some carnivorous dinosaurs gradually became smaller and more like birds.
"Gradually" means that after a long period of change, it gradually becomes smaller, not overnight.

(Courseware demonstration)
"The discovery in Liaoning shows the world the evidence that dinosaurs had feathers, which is the finishing touch for this painting drawn by paleontologists."
("The finishing touch" refers to the most important and critical content. In vivid language, the author compares the long research course and achievements of paleontologists to a "picture scroll". And to prove that dinosaurs evolved into birds, "feathers" are a very key part. The discovery of dinosaur fossils with feather marks provides strong evidence for research work and accelerates the process of this research. So it is the "finishing touch". )
(4) Guide emotional reading and experience the mood of scientists during research.
Design intention: guide students to discover the internal relations of things in comparison, learn to think and find problems.
2. Paragraph 5.
(1) Read the text together. What kind of wishes do scientists have?
I hope to find more and more sufficient evidence to reproduce the historical process of dinosaurs flying into the blue sky. )
(2) Tell me about your understanding of the sentence "Scientists want to reproduce this historical process".

Fifth, assign homework after class and sublimate the learning content.
1. Retell the evolution of dinosaurs flying into the blue sky to their parents.
2. For questions you don't understand and questions you want to know, you can consult books or check online. Exchange the collected information and hold the exhibition "Dinosaur World".
Design intention: to guide students to participate in extended Chinese learning, deepen learning content, broaden their horizons, develop students' personality and improve their Chinese practical ability.
