1.The soldier rushed into the cave, his right hand ________ a gun and his face ________ with sweat.
A held; covered B. holding; covering
C. holding; covered D. held; covering
解析：独立主格结构，his right hand 与hold有主谓关系，故用holding,而 his face与 cover是动宾关系，故用covered.
2. The girl in the snapshot was smiling sweetly, her long hair _________.
A. flowed in the breeze B. was flowing in the breeze
C. were flowing in the breeze D. flowing in the breeze
解析：her long hair 与 flowing 是主动关系，这是“独立主格结构”作状语。
3.The children went home from the grammar school, their lessons _________ for the day.
A. finishing B. finished
C. had finished D. were finished
解析：因lessons与动词finish之间为被动关系，故要用过去分词。其实，their lessons finished for the day为独立主格结构。
4.On Sundays there were a lot of children playing in the park, _________ parents seated together joking.
A. their B. whose C. which D. that
解析：此题容易误选B，认为这是非限制性定语从句。其实，句中的their parents seated together joking 不是非限制性定语从句，而是一个独立主格结构，因为空格后的动词 seated 不是谓语，而是一个过去分词，因为 seat 作动词用时，是及物动词。
5. The Smiths are rich and they have three cars, one a Toyota, ________ Land Rover of the latest.
A. another B. other C. the other D. the others
解析：易误选C。后面部分实际上是独立主格结构形式，省略了being。补充完整就是：The Smiths are rich and they have three cars, one being a Toyota, the others being Land Rover of the latest. (两个独立主格结构均表伴随状语)
