【答案解析】 1．第1句的主干是“孔子学院是机构”：宾语“机构”的修饰成分有两个——“中国在世界各地设立的”和“教育和文化交流(的)”，其中后者是对性质的说明，故可译为介词短语of education and cultural communication，作后置定语；而第一个修饰成分中具有动词“设立”，故可考虑译为过去分词短语established by...，作为后置定语修饰“机构”。
   2．在第2句中，可将“目的”译作句子主语，用动词不定式作句子表语，避免句子头重脚轻。
   3．第3句较长，其主干结构为“最重要的工作是提供教材和渠道”；可使用动词不定式to provide...作句子表语；“汉语学习”也可译作动词不定式to learn Chinese，作formal channel的后置定语。
   4．第4句中的两个分句逻辑主语有所不同，分别是“首家孔子学院”及“孔子学院”，可考虑译为两个独立的句子。其中，“遍布106个国家”可译为被动语态be established in 106 countries。
   5．“有力地”可译为greatly，用于修饰“推动(promote)”。
