2.Pottery is one of the oldest and most useful of all of the arts.
3.Archery is the technology by which a person uses the spring power...
请问是否有语法错误？
第一句我是删去了主谓。不过第一句的“the very farmers”，第二句的“of all of the arts”，第三句的“by which a person”，确实没什么语法错误和其他错误吗，读起来不顺口啊。

Answer 1

没有什么语法错误。第一条不成“句”是因为略去了主句的主谓，但不影响理解。

追答

读多了就顺口了。
the very farmers 中的 very 是形容词，意思是“实实在在的”；
of all of the arts 前面有 the most，形容词最高级的用法：the most ...... of ......
all of：all 是名词
by which a person......：介词短语。其中的 名词性从句 which a person uses the spring power 是介词宾语

Answer 2

He spent the whole day sitting beside the river but got nothing at the end of the day.

Answer 3

这些句子是完整的吗?
Archery是人名吗？

追问

第一句主句删了，第三句后面一段删了。不过第一句的“the very farmers”，第二句的“of all of the arts”，第三句的“by which a person”，确实没什么语法错误和其他错误吗，读起来不顺口啊。Archery就是弓箭术的意思。
