1 主语是the two captains，谓语是set （out）。amid XXX 整个是状语
2 从细小的方面去考虑
3 你是指was, indeed, art of, by, and for ordinary, everyday “folks”这里？拆开就是。American folk art was art of, by, and for ordinary, everyday “folks”。表示关于“人民”的，由人民制作的，面向人民的艺术。
剩下明天再来看。。

25.With spontaneous irreverence, satire rearranges perspectives, scrambles familiar objects into incongruous juxtaposition and speaks in a personal idiom instead of abstract platitude.

提取S-V-O：
satire rearranges perspectives, scrambles familiar objects and speaks
就是描述satire的惯用写作手法，LZ可以对局部S-V-O进行分析，然后就懂了

34.A few art collectors James Bowdoin III of Boston, William Byrd of Virginia, and the Aliens and Hamiltons of Philadelphia introduced European art traditions to those colonists privileged to visit their galleries, especially aspiring artists, and established in their respective communities the idea of the value of art and the need for institutions devoted to its encouragement.

提取S-V-O：
Collectors introduced art traditions and established the idea and the need.

introduce sth. to sb.
sb.=those colonists[(who were) priviledge to do sth.]

privilige:
transitive verb
:to grant a privilege to

noun
: a right or immunity granted as a peculiar benefit, advantage, or favor : PREROGATIVE especially : such a right or immunity attached specif. to a position or an office

36.Therefore, if the Earth began as a superheated sphere in space, all the rocks making up its crust may well have been igneous and thus the ancestors of all other rocks.

1 关键词解释
igneous
:formed by solidification of magma <igneous rock>
produced under conditions involving intense heat; "igneous rock is rock formed by solidification from a molten state; especially from molten magma"; "igneous fusion is fusion by heat alone"; "pyrogenic strata"

igneous rock
:igneous rocks are new rocks, formed when hot magma rises up from inside the Earth and solidifies. Intrusive igneous rocks do not reach the surface, but form bodies of rock within the crust.

2 关键词理解
-its:指代Earth
-thus: : in this or that manner or way <described it thus> 表示“同理可得”

3 S-V-O
all the rocks may well have been igneous and thus the ancestors of all other rocks 本句通过thus承前省以实现conciseness，完整句型为：
all the rocks may well have been igneous and thus the ancestors of all other rocks may well have been igneous

如有不对之处，望LZ进一步讨论

25.With spontaneous irreverence, satire rearranges perspectives, scrambles familiar objects into incongruous juxtaposition and speaks in a personal idiom instead of abstract platitude
Satire改变了写作方向，将大家熟悉的东西矛盾地摆在一起，并且以俚语写出来。<基本的看出来这三个词 不用知道每个单词的意思就可以大致知道它讲什么了>

A few art collectors James Bowdoin III of Boston, William Byrd of Virginia, and the Aliens and Hamiltons of Philadelphia introduced European art traditions to those colonists privileged to visit their galleries, especially aspiring artists, and established in their respective communities the idea of the value of art and the need for institutions devoted to its encouragement
这题其实不用翻译 LZ应该知道。不难。
简单的结构：** introduced ** to ** and established ** and ** . <这里有一个平行的结构 the idea of ... and the need for...>

36.Therefore, if the Earth began as a superheated sphere in space, all the rocks making up its crust may well have been igneous and thus the ancestors of all other rocks.（怎么觉得没说完……）
这句你的问题是?
