3.详细解说
1.“Where are you off to?”相当于“Where are you going?”,意思是“你要去哪儿?”。
2.“for a change”在这里可译为“换换口味”,“change”在这里用作名词,可以解释为: something which is pleasant or
interesting because it is unusual or new,即“因为新奇而美好有趣的事物”。例如:How about dinner out for a change?(我们换换口味,出去吃饭怎么样?)It's nice to see her smile for a change.(看到她偶尔能笑一笑,很不错。) We've always had a red car;it's time we had a change! (我们总是开一辆红色的车,也该变一变了!)
3.“besides”在此对话中用作副词,意为“此外,而且”。
