1.A BBC correspondent was taken to a mountain ridge which the military said had been an important Taliban base until its recent capture.

【参考翻译】一名BBC记者被带到一座山脉，军方称，在被占领之前此地一直是塔利班分子的重要基地。

【结构分析】which 引导定语从句，修饰mountain ridge。不要被the military said弄混了，这只是一个插入语，表示这是某人说的，去掉这个成分之后句子也还是完整的。

2.Mr. Munyaneza was arrested in 2005 in the suburbs of Toronto where he’d been living with his family after seeking asylum in Canada, a request that was turned down.

【参考翻译】Munyaneza于2005年在多伦多郊区被捕，在寻求收容失败后，他一直与家人居住在这里。

【结构分析】he’d been living 是现在完成进行时，只不过在这里是过去时态。表示从某个时间到现在动作一直在进行。
a request同位语，指代asylum。that was turned down是定语从句，修饰request。

3.A top security official in Mexico has resigned following the release of footage from a prison’s security camera, showing inmates walking out of jail in northern Mexico as guards stood by.

【参考翻译】由于监狱内外的监控录像显示，狱卒眼看着53名罪犯与一名持枪的武装分子从监狱中走出来（却没有阻拦），墨西哥高级安全官员辞职。

【结构分析】句中有三个过去分词短语，following the release of是伴随状语，showing inmates是后置定语，修饰security camera。walking out of jail是宾语补足语。
