1.There are signs that the recent short trials of some of the reformist politicians and journalists in which they have been allegedly confessed to be in part of the foreign plot are pushing Iran into more uncertainty.

参考翻译：在最近对一些改革派政治家和记者的审讯中，他们被指招供了自己是外国阴谋的一部分。这些审讯使伊朗的形势更加不确定。

结构分析：这句话的主干是There are signs……that引导的是同位语从句，指代的是signs。the recent short trials are pushing Iran into more uncertainty是同位语从句。in which they have been allegedly confessed是定语从句，修饰trials。

2.The election has been beset by allegations of fraud and corruption and concerns about a low voter turnout, raising questions about how credible the process has been.

参考翻译：由于有人指控选举诈骗和腐败以及担心投票率低等问题，选举曾经遭受围攻，这引发人么对选举过程诚信度的质疑。

结构分析：这句话的主干是The election has been beset，by allegations of fraud and corruption and concerns是施动者。raising questions是现在分词做结果状语。
