1.That could rise if prosecutors decide also to charge him with the murder of an unborn child being carried by one of his victims.

参考翻译：如果检控官最终决定同时控告他谋杀其中一名受害者腹中的胎儿，该数字还会上升。

结构分析：这句话的主干非常简单，就是前面的That could rise。后面是if引导的条件状语从句。being carried by one of his victims是现在分词作后置定语，修饰unborn child。

2.He will be prosecuted in a military court，if convicted, he could face the death penalty, although no one has actually been executed under the US military justice system for almost 50 years.

参考翻译：他将在军事法庭接受审判。一旦罪名成立，他将面临死刑判决，尽管自美国军事司法体系成立近50年来还从未真正执行过死刑。

结构分析：if convicted是省略形式，if he was convicted,如果他被判罪。although引导让步状语从句。

3.President Obama is still considering his options over whether to send thousands more US troops to Afghanistan after the American ambassador in Kabul argued against further reinforcement.

参考翻译：美国驻喀布尔大使表示反对增兵之后，奥巴马总统正在考虑是否向阿富汗增派更多军队。

结构分析：这句话的主干是President Obama is still considering his options，over……对某事的思考。after引导时间状语从句。
