Examination

Title - a key for us to grasp the content and ideas of the text.

What does the title of this article tell our readers?

(1) The main content of this article: the long-term blueprint for the development of the bridge industry.

(2) The characteristics of the times in the content of this article: the future tense is imaginary.

Please summarize the main content of the article in one sentence?

This article is an explanatory article that uses a scientific spirit to create a bold and reasonable imagination and vividly describe the bridge of the future. The article first explains the importance of the bridge and the basic structure of the bridge, and then describes the "bridge perspective" in detail, which is novel, unique and amazing.

The full text is divided into two parts

The first part (paragraphs 1-2) explains the importance of the bridge and its structure.

The second part (paragraphs 3-13), specifically envisions the bridge's long-term view.

The second part can be divided into three levels:

(1) First level (3-4): Introduction and explanation of the importance of future bridges.

(2) Second layer (5-8): It shows that bridges in the future will be built faster, cheaper, more beautiful, lower and more convenient.

(3) The third layer (9-13): Boldly envisions the future development prospects of the bridge.

What is the purpose of quoting the mythical story of the Cowherd and the Weaver Girl meeting on the Magpie Bridge at the beginning of the text?

It explains the important role of the bridge while increasing interest and readability, which can not only arouse young readers' interest in reading, but also stimulate their imagination.

Read the second paragraph aloud and tell us what parts the bridge is made of?

Piers, bridges, foundations.

In the second paragraph, a metaphor is used to explain it. Please find it and tell us what the expression effect is?

What is a bridge? It's just a bench. Visually illustrates the structure of the bridge.

What changes will happen to bridge construction in the future? Find the central sentence.

1. Bridges in the future must be built quickly and well.

2. Bridges in the future must be built very cheaply.

3. The bridge in the future will definitely be beautiful.

4. Bridges in the future must be built very low. Appreciate this section in detail.

What changes will happen to bridges in the future?

1. There are no bridge piers in the water.

2. Build a bridge over deep water.

3. Curved bridge.

4. It is small and lightweight and can be carried anywhere.

5. Flying without beams.

What explanation methods are used in this article? for example.

For example: bridge openings can be made of extremely lightweight materials such as glass. For comparison: Because the opening and closing of the bridge hole is very slow, it is inconvenient for the opponent to pass the boat by car. The machine that opens the bridge hole is also much more flexible than the current one, so the time for opening and closing the bridge hole can be greatly shortened.

Common explanation methods: defining, giving examples, listing numbers, making analogies, making comparisons, classifying, drawing charts, etc.

Language Features:

The language of this article is simple, concise and vivid. At the beginning, the mythical story of the Cowherd and the Weaver Girl meeting on a magpie bridge is used to illustrate the important role of the bridge, which can arouse readers' interest in reading and stimulate their imagination. It is really appropriate and clever. When explaining the structure of the bridge, the metaphor of "a bench" is very appropriate. In addition, rhetorical techniques such as comparison, parallelism, and quotation are used to make the article vivid and full of literary color.
