How People Spent Their Holidays
As can be seen from the table, the past decade have witnessed dramatic changes in the way people spent their holiday between 1990 and 20xx.In 1990, 63% of people spent their holidays at home, while the figure dropped considerably to 24% in 20xx. It is obvious from the table that people tended to be more and more mobile, and they wanted to get entertainment in the outside world. What contributed to these changes? I think the reasons are as follows. To start with, with the rapid development of economy, people earn by far more money than they used to. Thus, people are able to afford traveling expenses. Secondly, people think it important to get well-informed about the outside world in this new era when everything is on the move. Traveling, of course, is a sure way to achieve this goal. What's more, in this competitive society, people are usually under great stress. However, it is not difficult to find traveling an effective way to relieve people's stress and get relaxation. Last but not least, by traveling outside, people are close to nature, which is not only beneficial to both their health and peace of mind.
In conclusion, people prefer to go traveling rather than stay at home during holidays for a
combination of reasons. Moreover, it seems that this trend will last in the foreseeable future.
