完形填空

We are told breakfast is the most important meal of the day, and dinner the most enjoyable. But what about lunch? In today’s fast-paced society, not many people take time to enjoy this midday meal. We just take a quick salad, or buy a sandwich and eat at our computers. Sometimes, if there is a deadline around the corner, we just give up lunch. The development of technology hasn’t done our eating habits much good, either. We are constantly distracted(分神) by e-mails, social media, 24-hour news, and hand-held electronic devices.

Long working hours can cause all kinds of health problems. Employers should encourage workers to take time off for lunch. This is because long lunch breaks can benefit both people and society. To take a lunch break is to slow down and gain some views. A break from work allows us to think cleverly and outside the box. It also puts our daily tasks into a wider context(环境).

What we eat at lunch is also important. A fast-food lunch is more harmful than not having lunch at all. And it’s not just about calories and unhealthy food. Recent studies show that fast food also has negative effects on how we think. However, if we sit down at a proper restaurant and chat leisurely with colleagues, we are more likely to slow down and talk about something that hardly can be achieved in a noisy and crowded fast food chain.
