1.Instead of trying to keep down the body temperature deep inside the body,
which would involve the expenditure of water and energy, desert mammals
allow their temperatures to rise to what would normally be fever height, and
temperatures as high as 46 degrees Celsius have been measured in Grant’s
gazelles.（which 究竟修饰的是什么？）
2.Implicit in it is an aesthetic principle as well that the medium has certain
qualities of beauty and expressiveness with which sculptors must bring their
own aesthetic sensibilities into harmony.（as well 是什么作用和意思？that是不是修饰的是principle?）

我的理解：
1、指代trying to keep down the body temperature deep inside the body，这个动作是一个消耗水和能量的事

2、as well指的是除了certain qualities of beauty and expressiveness以外，含蓄也是美学的一个原则
implicit in it主语
is 谓语
an aesthetic principle宾语
