高考英语语法：过去分词表示状态例题解析
有这样一道题：
The murderer was brought in, with his hands _________ behind his back.
A. to be tied
B. being tied
C. tied
D. having tied
【分析】答案为C。从意义上看，hands 与 tie 的关系应属被动关系，故排除D。在A、B、C三个选项中，选项A比较容易排除，因为不定式表示将来意义，在此与语境不符。
现将B和C作一比较：
B为现在分词的被动式，它表示两层意义，一是表被动，二是表进行，也就是说 his hands being tied 的实际意思是“他的手正在被捆住”，这显然与语境不符。
C为过去分词，它也表示两层意义，一是表被动，二是表示动词的完成或完成后的状态，此句中的 with his hands tied behind his back 可视为手被捆在背后的一种状态。由此可知答案为C。
请看下面一题：
Anyone _________ trying to take knives on heard flights would be caught by the police.
A. finds
B. found
C. being found
D. will find
答案选B而不选C，其中的过去分词表示被动和完成。
比较下面两题，答案是D不是A，现在分词的被动式表示被动和进行：
(1) The court hears about 120 cases a year; visitors are welcome to see a case _________.
A. argued
B. to be argued
C. to be arguing
D. being argued
(2) The silence of the library was sometimes broken by an occasional cough or by the sound of pages _________.
A. turned
B. having turned
C. to be turned
D. being turned
