Lop Nur The vanishing fairy lake What do we do, it can regain its former vitality

1. What was Lop Nur like in the past, and what has it become now? Try concise language to summarize and summarize the reasons for the change.

This question requires a comprehensive grasp of the content of the text, and the ability to generalize and summarize is cultivated. The three aspects of the question suggest the starting point for the overall grasp, and inspire students to grasp the content of the text as a whole, first analyze the content of the text into several basic aspects, and then summarize them separately.

Lop Nur used to be a vast, beautiful and vibrant lake, and Lop Nur was surrounded by an oasis of life surrounded by cattle and horses, green forests and clear rivers.

Now it has become a dead desert, and the poplar forests are dead in patches, and there is no grass and no birds, which is terrifying.

The reasons for the change are: first, the Tarim River was artificially diverted in the 20s of the 20th century, resulting in drought and water shortage in the lower reaches; The second is the blind abuse of the water resources of the Tarim River, resulting in the drying up of the downstream rivers and the cutting off of water in Lop Nur, and the complete destruction of the ecological environment.

Second, the words of the article are full of a strong sense of distress, some are straightforward, some cite data, find a few such sentences, and experience their respective roles.

This question grasps the characteristics of the expression mode of the text, and makes appropriate prompts to let students figure out the sentences with expressive effect.

Straightforward sentences, such as "At this moment, we stopped laughing. That huge yellow sand pierced our hearts deeply and made our hearts heavy." It directly expresses the painful and heavy feelings in the heart, powerfully sets off the tragic situation of Lop Nur and reinforces the tragedy of ecological destruction.

Or "The author of this tragedy is a man!" "To point out that the disappearance of Lop Nur is the result of man-made ecological destruction is a strong condemnation of the blindness and ignorance of the tragedy makers.

Another example is "save Qinghai Lake, save the crescent spring, and save all the places that are about to become deserts due to human intervention", which issued a strong call to save the ecological environment, expressed a strong sense of environmental protection and worry, and was deafening.

There are more sentences that cite data, such as "In the past few decades, more than 130 reservoirs have been built in the Tarim River Basin, 138 water intakes have been dug at will, and more than 400 pumping stations have been built, some of which have to pump more than 10,000 cubic meters of water a day." A series of concrete and conclusive data fully illustrate how people blindly and desperately abuse the water resources of the Tarim River, and it is this blind behavior that has caused the desertification of Lop Nur.

4. Dongting Lake Poyang Lake.

Lop Nur, The Vanishing Fairy Lake is a reportage that begins with a vivid depiction of the desert scene of Lop Nur today, and then traces the beautiful scenes of history. Then it focuses on the reason for the demise of Lop Nur, and then specifically shows the desert scene of Lop Nur today. Finally, by extension, when it comes to the decline of Qinghai Lake and the crescent moon rolling spring, a strong appeal for saving the ecological environment is issued at the end of the article.

This article is a report or literature, and students are required to grasp two points in terms of content: one is to summarize the reasons for the disappearance of Lop Nur in the process of comparing the past and present of Lop Nur, and the other is to establish a correct ecological awareness on the basis of feeling the author's regret for the disappearance of Lop Nur, and to make suggestions and suggestions for protecting the spring and improving the ecological environment. In terms of expression, it is required to grasp three points:

The first is the three expression techniques of contrast, personification and comparison, and the second is a variety of expressions.

The problem has been in the last 30 years. The population on both sides of the Tarim River has exploded, and so has the demand. Arable land needs water, mining needs water, and people desperately ask for water from the Tarim River.

In the past few decades, more than 130 reservoirs have been built in the Tarim River Basin, 138 water outlets have been dug and distilled at will, and more than 400 pumping stations have been built, some pumping stations pumping 10,000 cubic meters of water a day.

Blindly increasing the use of water for cultivated land, blindly building reservoirs to intercept water, digging embankments to divert water from their own eyes, and blindly building pumping stations to pump water, the "four blinds" are like huge water suckers, and finally the Tarim River has been drained. Lop Nur, cut off from water, became a dead lake, a dry lake. After Lop Nur dried up, the surrounding ecological environment deteriorated immediately, all herbaceous plants died, the poplar forests of the sand control guards died in patches, and the desert quickly advanced into the lake.

Lop Nur soon became one with the vast Taklamakan Desert. Lop Nur is gone.

The diversion of the Tarim River and the "four blinds".

1. Loneliness and desolation.

Dry: No water.

Devour: Devouring, swallowing. Swallow whole.

Vicissitudes of life: A metaphor for great changes in the world.

2. Xiao Hun.

5. The article begins: "There is a Lop Nur on the edge of the Taklamakan Desert. "The interruption of the Tarim River has led to severe desertification in the lower Tarim reaches, causing Lop Nur to be covered by the Taklamakan Desert.

There are a large number of scene descriptions in paragraph 22, which sets off the desolate atmosphere on the edge of Lop Nur, and sets off the sadness in the author's heart and the helplessness and sadness of powerlessness.

8. Give examples. Write about the decline of Qinghai Lake, and call on people to protect the environment and not let Qinghai Lake disappear again.

9. The vanishing Lop Nur is the explanatory content that summarizes the full text, and takes Lop Nur as the object of explanation. At the same time, the disappearance contrasts with the fairy lake, expressing the author's regret. Such a beautiful lake has been extinguished by the blind use of water by human beings, which is a wake-up call to the world and awakens the awareness of human protection.

10. Discarding is passive, discarded for objective reasons. Abandonment is active, abandoned, discarded for subjective reasons. In the text, it is abandoned because of the drought and lack of water in the lower reaches of the Tarim River, and it cannot be discarded.

Collapse emphasizes the process of collapse, collapse and collapse. Collapse is simply collapse. So collapse is more specific, and it is better to use collapse.
