家中度假(staycation)是指一个人或一家人待在家里休息，或者在离家不远的景点游览的一段时光。人们在家中度假的原因很多，如家庭预算紧张、出游成本不断攀升，或者孩子太小。对于大多数中国人来说。节假日期间景区人山人海，高速公路、城市道路拥堵(congestion)，是促使他们家中度假的两大主要原因。常见的家中度假活动包括在家里招待朋友、游览当地的公园和博物馆，或参与当地一些节日活动等。家中度假也可以丰富多彩，它将成为一种新的度假趋势。

1.第一句话中的主干结构为“家中度假是指...一段时光”，因为定语过长，可将定语处理成which引导的定语从句。四级分值分布

2. “如家庭预算紧张、出游成本不断攀升，或者孩子太小”具体列举人们在家中度假的原因，翻译“紧张”、“攀升"和“太小”时可采用“形容词+名词”的结构，即like tight familybudgets, rising travel costs or having very youngkids，比较符合英文表达习惯。

3.在“节假日期间景区人山人海，高速公路、城市道路拥堵，是促使他们家中度假的两大主要原因”一句中，“景区人山人海”和“高速公路、城市道路拥堵”都是主谓短语，可理解成“人山人海的景区”和“拥堵的高速公路、 城市道路”分别译作overcrowded tourist sites和congestion on expressways and city roads，符合英文中多用名词表达的语言特点。

4.最后一句由两个分句组成，可译为两个并列句，用连接间and连接。
