Look at the weather from the clouds.
The article first talks about the relationship between different forms of clouds and weather. Paragraph 1 is an overview with a unique language. Always said, "The clouds in the sky are really changeable." Next, the author uses metaphor and parallelism to describe the myriad poses of the cloud very vividly, which can stimulate readers' imagination. To learn this language, teachers should familiarize students with it, appreciate the beauty of the language, imagine the wonderful changes in the blue sky and white clouds, and even let students imitate writing.
The following four paragraphs specifically introduce the relationship between cloud morphology and weather. The second paragraph is the outline of the next three paragraphs: thin clouds are often a symbol of sunny weather; Low and thick clouds are often a sign of rain and snow. The teacher reminds the students to think: Why do you use "often" and "often" as restrictive words here? Is it okay? The last three paragraphs follow this "outline". This is the main idea of the article. The teacher should guide the students to clarify this idea. Clear your mind and you won't be blind when you read the article.
Specific to a paragraph, there are also ideas. The third paragraph corresponds to "thin clouds" and "clear" in the second paragraph. How many kinds of thin clouds are there? What are the characteristics of thin clouds? Thin clouds can be divided into cirrus, cirrocumulus, cumulus and cumulus. They have their own characteristics and similarities. Teachers should guide students to find out their own characteristics and similarities. This paragraph is divided into four layers, which is very clear. Teachers can let students write by themselves. The author's clear thinking is expressed by classifying other methods. There are four kinds of thin clouds, which are introduced in an orderly way, and are worth learning and learning from.
Paragraphs 4 and 5 correspond to "thickness" and "rain and snow" in paragraph 2, and the writing ideas are the same as those in the above paragraphs. Starting from paragraph 6, the article turns to another meaning, that is, "the relationship between the brilliance of clouds and the weather." It should be said that "the brilliance of clouds" is covered by 1 paragraph "The clouds in the sky are really changeable", but the difference is that paragraphs 3, 4 and 5 are explained from the perspective of the relationship between cloud morphology and weather, and paragraph 6 is changed from the perspective of the relationship between cloud brilliance and weather. Teachers should guide students to see the change of interpretation angle and sum up their writing experience: they should be good at explaining things from different angles. According to the different brilliance of clouds, the author divides clouds into four types: halo, glow, rainbow and chardonnay. The author also introduces the difference between them, which is a comparative explanation. The author also quoted a proverb, explaining that it has been tested by people's practice and is a summary of life experience. The level of this paragraph is also very clear. This can inspire students to sum up the characteristics of clear paper writing level.
Characteristics of this article: 1. Clear hierarchy and purpose; 2. Be able to grasp the characteristics of the cloud to explain; 3. Vivid language, using rhetorical devices such as metaphor, personification and parallelism to write the cloud vividly; 4. Use classified interpretation methods.
Second, the problem research
1. This is a popular science article. Should the teaching focus be on learning meteorological knowledge? Or about the study of expository writing? Or both? If we focus on the study of weather knowledge, geography class will be easy. We should focus on studying the reading rules of articles and grasp the characteristics of such articles. The study of weather knowledge can be carried out properly, and it is impossible not to learn at all. But the study of weather knowledge should permeate the training of reading.
2. The name of the cloud is difficult to understand, which can be deepened by combining the colorful inserts in front of the textbook. For example, in the picture "Cirrus", cirrus is rolled up with small hooks. In addition, clouds are seen from the ground, not from the plane.
Practice note
Read the text silently and complete the following two questions.
1. The most basic experience of knowing the weather from the cloud is (in the original words of the article): _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
2. Design a table to list the types and characteristics of clouds and their brightness, as well as the weather conditions predicted by them respectively.
Reference answer:
1. This question examines students' ability to grasp the central sentence. The central sentence is "thin clouds in the sky are often a symbol of sunny days, and those low and thick clouds are often a sign of rain and snow." The way to solve the problem is: This paper mainly introduces the relationship between clouds and weather. Paragraph 1 describes the clouds in vivid language, and the last sentence summarizes and points out the center. The following text is a concrete explanation of it.
2. There are many kinds of clouds, which are difficult for students to master. By designing tables, students can master the types of clouds and understand the text more clearly. The idea to solve this problem is to divide clouds into two categories: according to their shapes, they can be divided into sunny clouds and rain and snow clouds; Then it is divided into four types according to the brilliance of clouds. The list is as follows:
Clear sky short list
Morphological changes of clouds, height and thickness, weather signs
Cirrus clouds are like feathers and silk tulle, and the tallest and thinnest clouds are floating continuously, symbolizing the sunshine.
Cirrocumulus is like a scale wave on the water, a cirrus cloud. It is very tall and thin, and there is no rain or snow.
Cumulus clouds, like cotton balls, appear in the morning and dissipate about 2 000 meters at night. The weather is fine and the air is thin.
Cumulus clouds are like snow-white sheep on the grassland, oblate and neatly arranged, about 2,000 meters thin and clear.

Second, some things are difficult to describe. For example, they are easy to explain and lively and interesting. Make sentences according to the following examples.
The clouds in the sky are like mountains, rivers, lions and galloping horses.
Make sentences:
1. As night falls, the surrounding mountains, ...
The neon lights in the distance are on, ...
This question aims to test students' mastery of figurative sentences (which should also be parallelism in form).
Reference answer:
1. At night, the surrounding mountains are like humps, such as city gates, such as reclining Buddha, such as long snakes. ...
The neon lights in the distance are on, like eyes, like meteors, like colored silk, like Changhong. ...
Solving this problem mainly depends on imagination and association. Starting from modeling, both static and dynamic are considered.
Choose one of the following two questions to carry out the activity.
1. From now on, take a time every day to practice watching the weather from the clouds, judge the weather of the day or the next day, and release the weather forecast in turn to see who can predict it accurately.
There are many folk proverbs about the weather. Please collect some after class (you can refer to the information or consult an experienced elder) and accumulate them by category.
