阅读下面的短文,并根据文章后的要求答题。

[1]We are told breakfast is the most important meal of the day,and dinner the most enjoyable.It is an occasion to socialize and spend time with the family.But what about lunch?

[2]In today's fast-paced society,few people take time to enjoy this midday meal.Most of us just rush right through it.We grab a quick salad,or buy a sandwich and eat at our computers.Sometimes,if there is a deadline around the corner,we just          

[3]The development of technology hasn't done our eating habits much good either.We are constantly troubled by e-mail,social media,and 24-hour news.Even When we do sit down for lunch,we are more connected to our hand-held electronic devices than ourselves.

[4]Long working hours can cause all kinds of health problems,and many developed countries have put in place labor laws specifically regarding the lunch break.These regulations give employees the right to take a break during a long work shift,but it's up to them whether they do so or not.

[5]Frank Partnoy,a former Wall Street trader,says that employers should encourage workers to take time off for lunch.This is because long lunch breaks can benefit both individuals and society.Writing in The Guardian,Partnoy says that one obvious reason to take a lunch break is to slow down and gain some perspective.A break from work allows us to think strategically and outside the box.It also puts our daily tasks into a broader context.If we sit down at a proper restaurant and chat leisurely with colleagues,we are more likely to slow down,something that hardly can be achieved in a noisy and over-packed fast food chain.

[6]Despite these benefits,some employees might still be unwilling to take time off for lunch.Partnoy's suggestion? Make skipping lunch difficult:Employers could ask workers to fill out a form stating their reasons for skipping the meal.
