Dinosaurs flying into the blue sky I think this text is a special problem, in all people's cognitive concepts, dinosaurs are huge and huge, how can they fly to the blue sky? Therefore, the author of a title of history set up a question to attract more people's interest. Therefore, through the study of the text, I understand how the dinosaur flying to the blue sky is sitting and how the changes around the dinosaur are highlighted, so it embodies Chinese culture, and the text contains different meanings.

I know, the question is how dinosaurs become birds.

I haven't learned this text yet, so I'll reply to it as soon as I learn it.

Why not use the title "The Evolution of Pterodactyls" or "Birds" and the Dinosaurs Flying into the Blue Sky instead?

Why did the author write a large number of words in the fourth natural paragraph?

Dinosaurs Flying into the Blue Sky mainly writes about a hypothesis put forward by scientists based on research: birds are likely to be descendants of a small dinosaur. At the end of the 20th century, Chinese scientists discovered dinosaur fossils with feather imprints for the first time in western Liaoning, which provided evidence for people to imagine that dinosaurs flew to the blue sky and changed into the evolution process of birds.

The text is about dinosaurs flying into the blue sky, which breaks the stereotype of dinosaurs in people's minds and is quite attractive. The article begins with a vivid presentation of the bulky, sluggish dinosaur and the light and nimble bird, two seemingly unrelated animals in people's minds.

Tell us that during the Mesozoic Era, one branch of the dinosaur evolved into a soaring bird, and then introduced the general process of this scientific discovery.

Specifically, it is about the evolution of dinosaurs into birds.

"Dinosaurs Flying into the Blue Sky" uses examples, numbers, analogies, and comparisons.

"Dinosaurs Flying into the Blue Sky" is a popular science article.

Dinosaurs Flying into the Blue Sky introduces people to a hypothesis put forward by scientific cautious hungry people based on their research findings: the black species are likely to be descended from a small dinosaur. The process of exploration that confirms the hypothesis opens the door to the science of paleontology.

The language is accurate and vivid, and the content is layered and interlocking.

The language of this text is accurate and vivid, and on the basis of careful reading, students can integrate their own knowledge about the evolution of dinosaurs according to the scenarios depicted in the text, rich and reasonable imagination. Adopt the learning method of questioning, "independence, cooperation, and cooperation", establish the awareness of students on the basis of understanding the text, and cultivate the spirit of students to study science.

Reflection on the teaching of "Dinosaurs Flying to the Blue Sky".

1. This article is a popular science expository text, so the content is more cumbersome, the first paragraph has a central sentence to return to the full text, the second paragraph tells the scientific research on the relationship between dinosaurs and Wu, the third paragraph has only one question in a transitional paragraph, and the fourth paragraph is the focus of the whole text, detailing how dinosaurs evolved into Wu, and which types of dragons have successfully evolved.

2. The last natural segment expresses the scientist's desire to find evidence that repeats the evolutionary history of dinosaurs. The focus of the text is to introduce the types and processes of dinosaur evolution, and the difficulty is to appreciate the accuracy and vividness of the wording in the expository text. The goal of the course is for students to be able to express the evolution of dinosaurs in their own words.

1. Body type.

2. Weight. 3. Huge families of different forms.

Original text: When it comes to dinosaurs, people often think of the ferocious Tyrannosaurus rex or the bulky, sluggish Mamenxi dragon; When we think of birds, we naturally think of light pigeons or colorful peacocks. The two may seem unrelated, but a large number of fossils found in recent years show:

During the Mesozoic Era, dinosaurs evolved one limb into a soaring bird.

As early as the 19th century, the British scholar Huxley noticed that dinosaurs and birds had many similarities in bone structure. After studying a large number of dinosaur and bird fossils, scientists have proposed that birds are not only related to dinosaurs, but are also likely to be descendants of a small dinosaur. According to this hypothesis, some dinosaurs that were closely related to birds should have had feathers, but no fossil evidence has been found.

At the end of the 20th century, Chinese scientists discovered dinosaur fossils with feathers preserved for the first time in western Liaoning, which immediately made researchers all over the world ecstatic. The discovery of Liaoxi showed the world evidence of dinosaur feathers, and painted the "finishing touch" to this picture painted by paleontologists.

This article is from Xu Xing's "Dinosaurs Flying to the Blue Sky".

Background: Dinosaurs Flying into the Blue Sky is a popular science article written by Xu Xing, which mainly introduces people to a hypothesis proposed by scientists based on research: birds are likely to be descendants of a small dinosaur. At the end of the 20th century, Chinese scientists discovered dinosaur fossils with feather imprints for the first time in western Liaoning, which provided evidence for people to imagine that dinosaurs flew to the blue sky and changed into the evolution process of birds.

The article not only reveals the major discoveries made by scientists in paleontological research, but also opens the door to the science of paleontology to students, arousing their strong interest in science.
