Learn the text

The article "Lovely Earth" introduces the characteristics of the earth and their benefits to human survival, arouses people's feelings of cherishing and treating the earth well, and emphasizes the significance of protecting the earth's ecological environment.

The text begins with the feelings of astronauts landing on the moon, which directly expresses their love for the earth, and the word "love" lays the emotional tone of the whole text. Then the author compares the earth with the moon and Venus to prove the loveliness of the earth. Then the author uses the phrase "the earth is very suitable for us" to transition to the following introduction to the earth. From the second paragraph to the seventh paragraph, the text introduces the characteristics of the earth and its benefits to human survival from the aspects of the earth's atmosphere, oblique axis, speed, gravity, climate and non-stop operation. Between the lines is full of love and praise for the earth. At the end, I quoted Colonel Anders's words-"I think we should jointly safeguard this tiny, beautiful and fragile planet", which was profound and thought-provoking and sublimated the author's feelings.

As this lesson is a skimming of the text, students can freely read and understand the loveliness of the earth during teaching. Students can read through the text first. Because there are many new words in this class, students should be given enough time to read and get a preliminary understanding of the text.

On this basis, starting with the central word of the topic "Lovely" and taking the question "What does the author say about the loveliness of the earth" as the general guidance, guide students to read the text carefully and organize students to exchange and discuss, thus solving the key points of this lesson. Secondly, it is difficult to quote astronauts at the end of the article. Guide the students to understand the meaning of this sentence and grasp the key word "tiny, beautiful and fragile" in the sentence. In connection with the full text, "small but beautiful" is easy to understand. The word "fragile" can guide students to think about the consequences of never being kind to the earth, and understand that the earth has both a beautiful and lovely side and a fragile side. The purpose is to remind people that, in addition, although this lesson is a scientific essay, the article is full of affection. Instruct students to read this article aloud. Teachers should instruct students to learn to grasp the meaning between the lines.

Words that accurately and appropriately express emotions capture the author's feelings.

Supplementary material

Only one earth

According to the astronauts who were lucky enough to fly into space, when they roamed in the sky, they looked at the earth from a distance and saw a crystal-clear sphere with blue and white lines intertwined and covered with a thin layer of water-blue "tulle". The earth, the mother of human beings and the cradle of life, is so beautiful, spectacular and amiable. However, the earth is a planet with a radius of only over 6,300 kilometers, just like a grain of sand in the starry universe.

Compared with the vast universe, the earth is small. The surface area of the earth is 5 1 10,000 square kilometers, and the land inhabited by human beings only accounts for about one fifth of it. In this way, the range of human activities is very small.

The natural resources of the earth are also limited. Take mineral resources as an example, it is not given by God, but formed by geological changes over millions or even hundreds of millions of years. The earth is selfless, and it generously provides mineral resources for mankind. However, if mining is not controlled, the mineral resources on the earth will be exhausted.

The water resources, forest resources, biological resources and atmospheric resources needed by human life could have been regenerated and contributed to human beings for a long time. However, because people destroy natural resources at will and abuse chemicals recklessly, it can't be regenerated, and it also causes a series of ecological disasters, which poses a serious threat to human survival.

Some people will say, isn't there a lot of space? There are countless planets there. When the earth's resources are exhausted, can't we move to other planets?

Scientists have proved that there is no second planet suitable for human habitation at least within 40 trillion kilometers centered on the earth. Humans can't expect to move to other planets after destroying the earth.

Yes, scientists have put forward many ideas, for example, building an immigration base on Mars or the moon. However, even if these ideas can be realized, how many people can survive?

"Our earth is lovely and fragile!" It was a sigh when the astronauts were invited to visit space and have a bird's eye view of the earth.

There is only one earth. If it is destroyed, we have nowhere to go. If all kinds of resources on the earth are exhausted, it will be difficult for us to replenish them from other places. We should seriously protect the earth and its ecological environment. Let the earth better benefit our future generations!

The structure of the earth

When our rocket has flown out of the solar system, our drill bit can only drill to the depth of 12 km. It's really "there is a road in the sky, but there is no road underground"! However, the change of seismic wave propagation speed and direction can reveal many secrets in the depths of the earth, just like using B-ultrasound to detect human internal organs. The earth has gradually evolved from a uniform sphere into four concentric spheres, namely, the inner core, the outer core, the mantle and the crust. The density of the solid core is l3 times that of water, the temperature exceeds 6000 degrees Celsius, and the pressure reaches 3.7 million.

Atmospheric pressure. According to the calculation, the substance existing in this state can only be iron. Iron meteorites falling to the ground, as fragments of the disintegrated planet, just confirm that the core is composed of iron and nickel. Although the composition of the outer core of the earth is mainly metal elements such as iron and nickel, it is a flowing liquid. The mantle with a thickness of about 3000 kilometers is mainly composed of peridotite, which is in a solid or semi-flowing viscous state at high temperature and high pressure. The thin crust is only 33 kilometers thick on average, with granite in the upper part and basalt in the lower part. In the ocean

The thinnest part of the shell is only 5 kilometers. Cracks appear in some parts of the earth's crust, and hot magma spews out from the upper mantle. This is a volcanic eruption.
