2. Grasp the characteristics of the overall structural arrangement, repeatedly taste and accumulate relevant proverbs.

Teaching emphasis: learn to explain things and astronomical phenomena in vivid language;

Teaching difficulties: master the characteristics of the "one point one total" structural arrangement, repeatedly taste and accumulate relevant proverbs.

Class schedule: 1 class hour

Teaching process:

First, the introduction of new courses.

On the blackboard, ask students to predict the content of the text according to their sense of language and talk about the role of the topic in the whole text.

Clear: This paper explains the relationship between clouds and weather, that is, by observing various clouds in the sky, we can distinguish between cloudy and sunny. The title summarizes the content of the full text.

Second, guide reading "preview tips" and master two key points of the text.

Third, guide the text reading and straighten out the text structure.

Requirements: 1. Find out the pronunciation and meaning of new words and phrases with the help of reference books.

2. Draw the sentences that you think are wonderful.

3. Taking the change of the cloud as a clue, focusing on seeing the clouds and knowing the sky, the text is divided into three parts to summarize.

Meaning.

4. What is the structure of this class?

5. Ask questions that you can't solve in reading.

Silk floss with bright flashing and dizzy signs.

The explanatory text is decorated with thousands of gestures, and the omen is light and scattered in an instant.

Text segmentation and general concepts.

The first part (1 natural section) is the close relationship between clouds and weather. You can know the weather by observing the clouds.

The second part (2-6 natural section) how to know the weather from the clouds.

The third part (7 natural section) is about the purpose, method and matters needing attention of knowing the weather through clouds.

The structure of this paper is "general theory-sub-theory-general theory".

Fourth, study the text and guide students to experience the vivid language of the text and the methods of classifying and explaining clouds.

1. Learn the first part.

① Thinking: Which sentences in the text explain the "myriad gestures" of the cloud? Which sentences explain the "impermanence" of clouds?

Chengming: Eight metaphors respectively illustrate the diversity of cloud forms, which are closely related to "myriad", "sometimes … sometimes … just … a moment" and "impermanence".

② What role does the last sentence of this paragraph play in the full text?

Clarity: Compared with the "signboard", it shows that the cloud is a sign of the weather, and you can know the weather by looking at the cloud, which leads to the center of the full text.

2. Think independently and analyze the second part.

(1) How many layers can this part be divided into?

Clear: two levels: the first level (3-5 natural sections), the relationship between cloud shape and weather.

The second layer (6 natural sections), the relationship between gloss phenomenon and weather.

② Read the text, fill in the form and finish the exercises after class 1.

3. Learn the third part.

① Discussion: What is the purpose and method of learning the weather from clouds? What are its limitations?

(Find the answer from the text)

5. Throughout the whole paper, discuss what interpretation methods are adopted in this paper.

Clear:

1. Metaphorical interpretation. For example, "sometimes like a white feather, sometimes like a white gauze" vividly illustrates the lightness and whiteness of cirrus clouds; "Like rippling waves caused by a breeze blowing over the water" is a metaphor for cirrocumulus's morphological characteristics; "White clouds like cotton balls" is a metaphor for the morphological characteristics of cumulus clouds.

2. description. For example, "the sun is still very clear through the clouds", which is the "thinness" of cirrus clouds; Write the development of cumulonimbus cloud to cumulonimbus cloud with words such as "upward bulge" and "tall Yunshan, where the peaks compete for each other and soar to the zenith"; "The cloud bottom turns black". The words "Cloudy Yunfeng", "Cloud Landslide" and "Cloudy" describe the development and changes of cumulonimbus clouds.

3. Explain, for example, "The lightest and tallest cloud is called cirrus." "There is also a kind of white clouds like cotton balls called cumulus clouds.

4. Quotations: For example, "People often say that the rainbow in the east thunders and the rainbow in the west rains"; "So there is a proverb," Don't go out at sunrise, a thousand miles away at sunset ",citing folk proverbs to explain the truth.

There are clouds hanging in the sky and it is raining. "

Hook cloud is called hook cloud in meteorology, which generally appears in front of warm front and low pressure. The appearance of hook clouds indicates that a front or low pressure is coming, which is a precursor to rain. But after rain or winter, there will be sunny days or frost, so there is a proverb that "the hook cloud dissipates, the sunny day is dry" and "the winter hook cloud dries up"

"The carp point in the sky, you don't have to turn over the grain tomorrow."

Carp spot refers to translucent cumulus clouds, and the air mass that produces this cloud is stable. In the evening, when encountering downdraft, the cloud dissipated faster, and it cleared up the next day. However, if the cloud looks like a tiny fish scale, it is cirrocumulus. This kind of cloud mostly appears in front of the trough of low pressure or around the typhoon, and there will be wind or rain in the near future. Therefore, there is a proverb "It doesn't rain, but it's windy".

"The clouds are heading east, blowing gusts; The clouds are going west, covered with hemp fiber. "

The cloud referred to here is the low cloud in the low pressure area. The low pressure is from west to east (in fact, it often moves from southwest to northeast). The cloud goes west, indicating that this place is in front of the low pressure, because it will rain locally; The cloud is moving eastward, indicating that the low pressure has moved past the local area, and the local area is behind the low pressure. The weather is going to clear up, and a strong wind often blows before it clears up.

"Where the clouds hook, where the wind comes from."

Cloud hook refers to the tail of hooked cirrus clouds, which appears at high altitude, sometimes with small hooks at the top and arranged in rows. The upper hook refers to the direction of the high-altitude wind, which is often connected with the ground, so the direction of the cloud hook can generally tell the direction of the wind.

"Dark clouds cover the morning, and the wind comes without rain."

It means there are dark clouds in the southeast in the morning, which indicates rain. Because the warm and humid southeast wind blows in the morning, the temperature is higher than the local air, which causes the upper part to be cold and the lower part to be hot, and the water vapor easily rises into clouds. In addition, during the day, the ground is heated, and the air convection rises, which further promotes the clouds to rise. When it meets cold water vapor, it becomes water droplets, which may make it windless and rainy.

"Huang Yun flies up and down, and it will lay ice eggs."

Most of the yellow clouds are caused by the strong rise of warm and humid air. In this case, there are many showers and hail.

"The mountain wears a hat, and the rain is coming."

Wearing a hat on the mountain means that the air pressure is low, and most of the water vapor in the air forms clouds at the top of the mountain. As for whether it will rain, it generally depends. If the clouds gradually decrease and thicken, there is a great possibility of rain. On the contrary, if the clouds gradually rise and thin, the possibility of rain is small.

"Clouds eat fog and fog eats clouds."

After seeing the fog, the clouds came. Maybe a low pressure is coming, which is a sign of rain. On the contrary, if the clouds clear, it means that the low pressure has passed and sunny weather is coming.
