The new curriculum study guides the seventh grade. The first volume tells the weather through the clouds.

As the saying goes: "There are unexpected clouds in the sky", is the change of rain or shine really unpredictable? What do people rely on to identify weather changes in their daily life and practice? (Student answers: Look at the clouds), indeed, clouds are like "signs" of the weather. The proverbs "Don't go out at sunrise, travel thousands of miles at sunset" and "There are clouds hanging in the sky and rain dripping on the ground" are the experiences of working people in understanding the weather through clouds in production practice. Today, we are going to learn a popular science article "Seeing the Clouds and Knowing the Weather", which will tell us how to interpret the words of nature and the "signboard" of the weather-floating clouds. (written on the blackboard)

There are two lines in Zhuzhi Ci by Liu Yuxi, a poet in the Tang Dynasty, which are novel and gratifying because of their humorous pun expression. Is the sunny and rainy weather in nature really as unpredictable as people feel? Besides the weather forecast, how can people recognize the weather changes? Yes, you can also use clouds floating in the air, so how do you predict the weather through clouds? Today, we will learn a popular science article "Seeing the Clouds and Knowing the Weather" to learn the knowledge of weather changes. (written on the blackboard)

2. Students are free to read and sort out the main contents of the text.

Thinking: (1) This article is a popular science article, mainly introducing the relationship between clouds and weather. What words match the topic and reveal the relationship between clouds and weather? What kind of explanation does it use?

(2) With regard to the relationship between clouds and weather, the article expounds from which two aspects, and finds out the sentences indicating the angle change.

(3) In the second paragraph of the article, the phrase "Understanding the weather through clouds" reveals the relationship between the shape of clouds and the weather. The author uses "Chang" and "Chang" as restrictive words. What does this mean? What does the last three paragraphs have to do with it?

(4) Compared with the detailed introduction of the relationship between clouds and weather in the main body of the text, the remarkable feature of the summary in paragraph 1 is the vivid metaphor, so try to analyze its function in detail.

(5) Summarize the writing ideas of the text in the form of a short form.

(1) Clouds are like "signboards" of weather. The billboard uses analogy, which means that clouds are a sign of weather changes, which accurately and vividly explains the relationship between seeing clouds and knowing the weather.

(2) The central sentence in the sixth paragraph, "We can also infer the weather according to the brilliant phenomena on the clouds", indicates the change of angle.

This paper introduces the relationship between cloud and weather from two aspects: cloud shape and cloud brightness.

(3) The use of these two words in sentences has a restrictive effect, which means that the general situation is like this, excluding special circumstances and reflecting the accuracy of the language.

The second paragraph is the "outline" of the next three paragraphs. The third paragraph corresponds to the "thin cloud" and "clear sky" in the second paragraph. Thin clouds are divided into cirrus, cirrocumulus, cumulus, and cumulus. Paragraphs 4 and 5 correspond to "thickness" and "rain and snow" in paragraph 2, and the clouds are divided into "cirrostratus", "high-level clouds", "nimbostratus" and "cumulonimbus clouds".

(4) Paragraph 1 uses a series of metaphors, which vividly describes the myriad gestures of the cloud and fully stimulates the imagination of readers. The author first explains that the cloud has "thousands of gestures": some are "like feathers", which means it floats lightly, and some are "like fish scales", which means it is arranged neatly; Some are "like a flock of sheep", which looks like its shape, and some are "like a big cotton wool", which looks like its texture; Like a mountain, like a river, like a lion, like a galloping horse This series of appropriate metaphors is vivid, concrete, vivid and impressive. The last sentence is the central sentence of the whole paragraph, and the word "signboard" is appropriate and intriguing. In a word, the use of metaphor not only makes the things to be explained more vivid, but also makes the whole article rich in literary talent and can stimulate people's interest in reading.

3. Read the full text and experience the distinctive features of the text.

Thirdly, discuss paragraphs 3 to 6 in detail.

1. Students read intensively, trying to find out the vivid image of the language.

2. Projection shows a photo of a thin cloud. Students are required to carefully observe the morphological changes of clouds in combination with the detailed description of the text, expand rich associations and express more creative understanding.

Thinking: Clear thinking in paragraph (1), expressed by classification. Please list the morphological changes, characteristics and predicted weather changes of sunny clouds in the form of a brief table.

(2) Paragraph 3 adopts the order of explanation from phenomenon to essence, so what is phenomenon? What is the essence?

(3) The language in the third paragraph is both plain and vivid, giving an example each.

(1) classification description method is a method to divide things into several categories according to certain standards and explain them one by one. This classification can not only make the different characteristics of different things clearer, but also make the explanation clearer. This paragraph divides the thin clouds into four types and introduces them in an orderly way. They have their own characteristics and similarities. The list is as follows:

(2) It shows that the shape of clouds is a phenomenon, and the relationship between clouds and weather changes is the essence.

(3) Description of the plain: Cirrus and cirrocumulus are very high, where there is little water, which generally does not bring rain and snow.

Vivid explanation: Altocumulus is a oblate cloud, which is arranged evenly. There is a blue sky between the clouds, which looks like a snow-white sheep on the grassland from a distance.

3. In narration, metaphor is a rhetorical method; In expository writing, using metaphor to explain things is called metaphorical interpretation, which is generally referred to as metaphor for short. The use of metaphor makes the article lively and interesting. Please follow the example to make sentences, start with the form, fully imagine and associate, and give consideration to both static and dynamic, so as to combine static and dynamic.

The clouds in the sky are like mountains, rivers, lions and galloping horses.

Make sentences:

(1) At night, the surrounding mountains, …

(2) The neon lights in the distance are on, ...

Students answer, teachers give examples:

(1) At night, the surrounding mountains, like humps, like gates, like reclining Buddha, like long snakes, ...

(2) The neon lights in the distance are on, like eyes, like meteors, like colored silk, like Changhong. ...

4. The writing ideas of paragraphs 4, 5 and 6 are the same as those of paragraph 3. Ask the students to mark the main points of the three paragraphs in the form of charts according to the analysis in the third paragraph.

1. Read the passage and complete the exercise.

Projection display:

The blue sky was covered with a silky cloud curtain, and in a short time, a colorful halo appeared around the sun. It is like a rainbow, but not as bright as a rainbow; The color arrangement of the rainbow is inner ultraviolet red, while the halo is just the opposite, which is outer ultraviolet red. This is the "halo", commonly known as the "wind circle".

People are interested in "halo" not only because of its colorful colors, but also because it is a precursor to weather changes. According to the statistics of Altay, Xinjiang, China, there were 1052 "halos" in 1980, of which 80% experienced obvious weather changes such as wind and rain within two days after "halos".

However, not all "rings" are signs of storms. After long-term observation, meteorologists found that when the duration of "halo" is within 1 hour (commonly known as "short halo"), there will be wind or rain from 12 hour to 36 hours in the future; When the "halo" lasts more than 5 hours (commonly known as "long halo"), there will be no stormy weather.

The beautiful light ring is the weather forecast map of nature. We can understand and use it to observe the situation and better arrange our work and life.

2. This paper successfully uses metaphor to explain, which not only makes people understand all kinds of clouds suddenly, but also looks lively and interesting, providing an example for our work. Metaphor is used differently in expository writing and narrative writing. In short, it means "letting people know" rather than "making people feel".
