[考題] 分詞構句？

[uniquekiller (和尚)]

請教各位
When trying to document a past incident,it is crucial that there be images available before and after the attack.
上面的trying 是分詞共構？因為我看兩句主詞不一致 因爲副詞是人但主要句是物 求給說明...

→ dunchee: 是分詞構句，"字面上"也確實是misrelated/dangling parti
→ dunchee: ciple，但是當主要主句的主詞是虛主詞 it 或 there 時，
→ dunchee: 這用法很常見(*1)。一個實例：
→ dunchee: https://tinyurl.com/yylblumv
→ dunchee: (*1)Swan的Practical English Usage有提。原說法是說
→ dunchee: misrelated participles的句子是..common and often seem
→ dunchee: quite natural, particularly ...[特別是 虛主詞 it or
→ dunchee: there ...]
→ uniquekiller: 所以可當特例去看待它？
