先谢谢大家了~~~~

是选对吗？

17

不懂

28

located表示是状语，所以B多谓语，D多个名词也不对。

A该是对的，C不清楚，只是觉得不通。

但是PP语法笔记里说28题的正确答案是B啊........偶也不懂...............@@|||||||

28. Located at the upper end of each____ an adrenal gland, an integral part of the endocrine system.

A. kidney which is

B. kidney is

C. kidney being

D. kidney

倒装结构，正常语序是：an adrenal gland, an integral part of the endocrine system, is located at the upper end of each kidney.

对倒装一窍不通.........

能告诉我为什么17的B是错的吗?.......
