Knowledge points of the fourth-grade Chinese language textbook "The Century of Mobility"
The 20th century is a century of unprecedented brilliance in science and technology. The author of the article clearly made it clear in just a few hundred words. It introduces the development of science and technology in the 100 years of the 20th century, demonstrates the tremendous changes and brilliant prospects that the rapid development of science and technology has brought to human life, and arouses students' strong interest in loving science, learning science, and exploring science.
The text begins with a grand opening, with only one sentence in the first paragraph, which explains a fact in an undoubted tone: the 20th century was a century of change. The author uses the ability of Taoist priests to use their magical power to "call for wind and rain" in myths and stories to describe the differences between the 20th century and the past.
In the second natural paragraph, the text uses two hypothetical questions in succession, which strongly illustrates that it is the continuous "discovery" and "invention" of human beings using modern science and technology that makes the mythical "movement of wind and rain" possible. ” has become a reality, which has greatly improved human life. The degree of change exceeds the sum of millions of years of human history, illustrating the practical significance of science and technology in changing human life.
The 3rd and 4th natural paragraphs are the key paragraphs of the article. The author uses the method of comparison and lists specific examples to cleverly reveal the significance of science and technology to human life: without science and technology, humans can only obey nature. Living in a "farming society" where people work at sunrise and rest at sunset, they can only "entrust their good wishes" in myths; but with science and technology, humans can transform nature and change their own way of life. It is no longer a myth to reach the heavens and the earth, so close to the end of the world. Modern science and technology have condensed the vast earth into a small "global village". "Science is changing the spiritual, cultural and spiritual life of mankind, and it is also changing the material life of mankind." It can be seen that science and technology play a huge role in changing human life.

How to learn ancient Chinese poetry for the fourth grade
Ancient poetry is a beautiful poem created by the ancients. The words are difficult to understand and the meaning is profound. So, how to learn ancient poetry well?
< p> 1. Understand the background of the timesPoets often use poetry to express their thoughts and feelings of love and hate, expose and criticize unreasonable social reality, and learn ancient poems for primary school students. Therefore, understanding the historical background of the poem is helpful to understand the content of the poem. For example, in the poem "Silkworm Woman", the poet used poetry to expose the unreasonable reality of "the one who works does not gain, and the one who gains does not work" under the feudal system, criticized the evils of the exploitative system, and expressed the poet's deep sympathy for the working people. Once you understand this background, it is easy to understand what the poem is about.
2. Check the meaning of the title
To understand the general idea and main content of the poem, you must first check the meaning of the title. For example, the meaning of the title "Early Departure from Baidi City" is: "Zao" means "morning", and "Fa" means "departure from...". The whole title means that the poet Li Bai "departs from Baidi City in the morning". After reviewing the meaning of the title, it will be easier to understand the content of the whole poem.
3. Master the meaning of words
The meanings of some words in ancient poetry are different from their meanings in modern Chinese. For example, in the poem "Mountain Journey", the word "sitting" in "Stop and sit in the maple forest at night" now means the verb "to sit down", but in the poem it is used as "because", which is very different from the current meaning. .
4. Understand the meaning of the poem
First understand the meaning of the words, and then connect the words to get the meaning of the whole sentence. For example, in the sentence "Chaoci Baidi Caiyunjian", first understand the meaning of "Chao Ci Baidi Caiyunjian". "Ci" means "Bai Di", and it will be easy to understand the meaning of the whole sentence. The whole sentence can be interpreted as "Leaving Baidi City among colorful clouds in the morning."
5. Understand the writing techniques of poetry
There are many artistic techniques in the writing of ancient poems, such as the use of metaphors, exaggeration, foil and other rhetorical techniques to highlight the artistic conception of the poem. For example, the sentence "You can pick the stars with your hands" in the poem "Staying at the Mountain Temple at Night" uses an exaggerated technique to write about the height of the building; The rich imagination of immortals is used to highlight the height of the building.
6. Discover the philosophy contained in poetry
Learning ancient poetry requires not only understanding the content and meaning of the poem, but also exploring the profound philosophy contained in the poem. For example, in the poem "Ascend the Stork Tower", for the poem "If you want to see a thousand miles away, go to a higher level", you must not only understand that the poem means "If you want to see the scenery far away, We have to climb to the next floor." We also need to understand the philosophy contained in the poem that "only by standing high can we see far."
7. Understand the poet’s feelings
On the basis of understanding the poetic meaning, you must also understand the thoughts and feelings expressed by the poet in the poem. For example, in the poem "Quequae", "The window contains the snow of Qianqiu in the Xiling Mountains, and the door is docked with ships thousands of miles away from Dongwu." This not only expresses the poet's broad mind living in the thatched cottage, but also expresses the author's feelings through the description of the bright scenery near the thatched cottage. Yearning for a peaceful life.
