1．将Travelled改为Travel（l）ing       考查现在分词的用法     此处在句中作时间状语，动词Travel与其逻辑主语you之间构成主动关系，故改为现在分词．
2．将where改为which/that或去掉where    考查关系词的用法     本句的句意为：出国旅行时，你应该遵循你所访问国家的风俗习惯；根据句意可知，本句是定语从句，先行词country在从句中作宾语，故用关系代词 which/that；另外，由于关系代词 which/that 在此处作的是宾语，故可以将其省略；即去掉where（关系副词，在句中作地点状语）
3．在invited之前加are  考查被动语态的用法   根据下文提到"拒绝或接受邀请是有礼貌的行为"可知，此处应表示：当你被邀请的时候；动词invite与主语you构成被动关系，这里表达的是外国通常的礼仪，应使用一般现在时，故用are 
4．将a改为the    考查冠词的用法    此处特指上文所提到的邀请，故用定冠词the
5． 将reach改为arrive    考查动词的用法   动词reach与arrive都是"到达"的意思；它们的区别在于：reach是及物动词，其后应跟宾语；arrive是不及物动词，其后不能直接跟宾语；由于此处没有宾语，故改为arrive
6． 将hand改为hands    考查固定短语的用法    固定短语shake hands with sb．意为"与某人握手"；故改为hands
7． 将and改为or    考查并列连词的用法    根据句意"如果你愿意，你可以带一份礼物，也许是一瓶酒，一盒巧克力或者是一些花"可知，此处表示选择关系；故用or
8．将was改为is    考查时态   由于本文讲述的是外国通常的社交礼仪，故应改为一般现在时is
9． 将before改为after      考查连词的用法     本句的意思是：在其他人离开后，在主人家呆得太晚是不礼貌的；before在…之前；故改为after
10．将late改为later   考查late与later的用法区别    late是"迟"的意思，later是"稍后、随后"的意思  此处意为："一两天之后"，故改为later．
