2. 第2 句的结构逻辑是“比较状语（与……不同）+ 城市漫步的特点（不追求A，而是做B）”。“与……不同”可用unlike、different from等来表达，后半句使用not... but rather...的结构来表达“不是……而是……”“。大街小巷”可直接表达为“街道（streets）”和“巷子（alleys）”，这实际上也是一个宽泛的表达，指代“城市的每一处地方”，故也可译为every corner of the city。
5. 第5 句的主干句式是“某事物能让某人做某事”，译为allow/enable sb. to do sth. 的句式即可。
◆参考译文
In recent years, “city walk”has been quietly emerging among young people in China and has become a new tourism trend. Unlike traditional sightseeing, city walk does not seek to visit as many attractions as possible in a short time, but rather involves walking freely or following themed routes through the city’s streets and alleys. The walkers taste authentic snacks, appreciate the distinctive architecture, and learn about the local lifestyle. They also use cameras or mobile phones to document the city’s scenes and people. This style of travel allows city walkers to gain a deeper understanding of the city’s history and culture.
