16. (Sorry, I didn't see a line).

1. Stone arch bridges appeared (comparatively) early in the history of bridges in the world.

This comparison is a more accurate description of the time when the stone arch bridge appeared, if it is removed, it is a general ancient bridge, which appeared earlier, and there is nothing special.

2. The "Traveler's Bridge" mentioned in the "Notes on the Water Classic" was built (approximately) in 282 A.D., and is the earliest (probably recorded) stone arch bridge.

It is about to say uncertain, but the front and back are about the same, and if you remove it, it will be determined that it was built in 282, which is not rigorous enough;

This may be documented, and it is about the same as the above, it is uncertain, and it is not rigorous enough to remove.

3. Stone arch bridges are (almost) everywhere in China.

It's almost said that there are a lot of meanings, but it's not really**have, if you go to almost become**have, it's obviously impossible, so this is almost a more appropriate statement.

4. The whole bridge has only one large arch, which is one meter long, which is the longest stone arch in the world (at that time).

Removing the word that could be considered to be the longest in the world at the time is to more accurately describe its status at that time.

The phrases in parentheses reflect the accuracy and rigor of the expository text.

Take the fourth sentence as an example, removing "it can be regarded at that time" makes the whole sentence appear to be a mistake in the rigor--- Zhaozhou Bridge was the longest arch bridge in the world more than 2,000 years ago, but it is no longer today.

Therefore, in summary, the words in parentheses cannot be removed, otherwise it will be inaccurate for the object to be explained.

It cannot be removed, and the meaning does not match the original meaning after being removed, which reflects the accuracy of the explanatory language.

1. The word comparison cannot be removed, and the word comparison limits the time when the stone arch bridge appeared in the history of bridges in the world from the scope, and it does not match the title after being removed, which reflects the accuracy of the explanatory language.

2 Approximate may be recorded and cannot be removed, the word approximate limits the time when the Traveler's Bridge appeared, and after being removed, it does not match the meaning of the title, reflecting the accuracy of the explanatory language.

3 The word almost cannot be removed, and the word almost restricts the scope of the appearance of the stone arch bridge from the scope, and it does not match the meaning of the title after being removed, which reflects the accuracy of the explanatory language.

4 At that time, it could not be removed, and at that time, it could be regarded as a term that limited the length of the stone arch of the stone arch bridge from the scope, and it did not match the meaning of the title after being removed, reflecting the accuracy of the explanatory language.
