Chinese stone arch bridge PPT, part 6 content: explanation method

Quote - Zhang Jiazhen of the Tang Dynasty said that it is "strangely made, and people don't know why."

For example - Chinese poets like to compare arch bridges to rainbows, saying that arch bridges are "lying rainbows" and "flying rainbows", and describing arch bridges on the water as "long rainbows lying on waves".

List of numbers - Zhaozhou Bridge is very majestic, with a total length of 50.82 meters, a width of 9.6 meters at both ends, and a slightly narrower middle section of 9 meters wide.

Copy the appearance - some of these stone lions are hugging each other, some are whispering to each other, some are like listening to the sound of water, and some are like watching passers-by. They are all different and lifelike.

Explanation - There are stone piers between every two stone arches, connecting the 11 stone arches into a whole. Because the arches are connected, this kind of bridge is called a double-arch stone bridge.

Chinese stone arch bridge PPT, part 7: language characteristics

1. This kind of bridge is not only beautiful in form, but also has a solid structure. (Can "not only" and "but also" be deleted? Can the order of "beautiful form" and "sturdy structure" be adjusted?)

Cannot be deleted. If deleted, the relationship between them becomes a parallel relationship. Let’s talk about appearance first, then function, which is in line with people’s cognitive logic. And for bridges, the practical value is far more important than the form, so the order of the two cannot be adjusted.

2. The "Traveler's Bridge" mentioned in "Shui Jing Zhu" was built around 282 AD and may be the earliest recorded stone arch bridge. (Can "about", "possibly" and "recorded" be removed?)

“About” and “possibly” both indicate uncertainty and are just speculation. "Recorded" adds reliability to the basis of the statement.
