2. Translate the following passage into English.
▆ Answers for reference:
Sara and Michael used to be a two-career couple with a home of their own, two cars and a large boat bought with a large loan. They were both busy with their respective work and sometimes they had to make business trips at weekend. The only time for their so-called home life was restricted to the few hours after work. Indeed, they had made a lot
of money, but they got fed up with such a fast-paced lifestyle. So soon after their daughter was born, they decided to change their lifestyles.
They traded their two full-time careers for two part-time jobs, and tried hard to curtail their consumption. They sold their splendid house and moved into a smaller but pretty and energy-efficient home designed by themselves. They downsized their possessions and discarded all the expensive clutter. They also sold their big boat and shared a smaller one with another family so that they could still enjoy sailing on the sea. They gave up the extra car and their professional wardrobes. They also gave up expensive hobbies. They seldom ate out, thereby reducing a lot of expenses. Now they no longer purchase things on impulse and only spend money on the bare necessities.
One may think that they are too stingy toward themselves. But that is not the case. For them it is a voluntary act to have chosen this simple and frugal lifestyle. It is by no means deprivation. They believe that a frugal life is beneficial to both society and the individual.

Healthy Lifestyles
Different people have different interpretations of a healthy lifestyle. To me, a healthy lifestyle means living in a way that helps us to be physically, mentally and emotionally healthy.
We can benefit a lot from living a healthy lifestyle. On the one hand, a healthy lifestyle can give us a strong body, increase our life expectancy, and help us form good living habits. On the other hand, a healthy lifestyle enhances self-esteem and confidence, reduces stress and pressure, and enables us to develop a positive outlook and live in harmony with each other. In short, a healthy lifestyle improves our overall sense of well-being and happiness.
There are many ways to develop a healthy lifestyle. We need to exercise regularly, keep a balanced diet, and avoid alcohol and cigarettes. It would also help if we could balance our time for work and play, and find ways to release stress and pressure. With such efforts, we will be able to live in a way that contributes to our physical, mental, and emotional health. (173 words)
