二、真题示例
题目：What are the main reasons for the increasing number of people choosing to live alone?
范文：
Recently, the increasing number of people choosing to live alone has become a noticeable trend. It is important to understand the reasons behind this phenomenon.
One of the main reasons is the pursuit of personal freedom. For example, living alone allows individuals to have more control over their living space and daily routines, which can lead to a greater sense of independence and autonomy.
Another significant reason is the changing social attitudes. Modern society places a higher value on individualism, and people are more accepting of different lifestyles, including living alone. This shift in attitudes has made it more socially acceptable for people to choose to live alone.
Additionally, economic factors also play a role. With the rise in income levels and improved living standards, more people can afford to live alone, even in expensive cities. This financial independence makes it easier for individuals to choose a lifestyle that suits their personal preferences.
In conclusion, the increasing number of people choosing to live alone is due to a combination of factors, including the pursuit of personal freedom, changing social attitudes, and economic independence. This trend reflects the evolving needs and values of modern society.
 
三、中文翻译解析
翻译：
最近，越来越多的人选择独居成为一个明显的趋势。了解这一现象背后的原因非常重要。
其中一个主要原因是追求个人自由。例如，独居可以让个人对自己的生活空间和日常安排有更多的控制权，从而带来更大的独立感和自主感。
另一个重要原因是社会态度的变化。现代社会更加重视个人主义，人们对不同的生活方式，包括独居，更加包容。这种态度的转变使得选择独居在社会上更加被接受。
此外，经济因素也起到了一定的作用。随着收入水平的提高和生活标准的改善，更多人能够负担得起独居的生活，即使是在昂贵的城市。这种经济独立使得个人更容易选择符合自己偏好的生活方式。
总之，越来越多的人选择独居是多种因素共同作用的结果，包括追求个人自由、社会态度的变化以及经济独立。这一趋势反映了现代社会需求和价值观的演变。
