Recreational Activities
There are a variety of recreational activities in society now,like sports games,singing karaoke,club activities and so on.
But when asked about how these amusements affect our life,people’s opinions differ.Some hold the opinion that these activities could benefit us greatly.First of all,we can relax ourselves through entertainments since we have been extremely tired dealing with our daily work or studies.In the second place,it might help us make friends with others,thus as a consequence,our eyes would become much more widely open.
However,on the contrary,other people claim that recreational activities would do harm to us for the reason that we cannot control us very well,which would wind up with the failure of our examinations or works.What’s more,if we haven’t been careful enough,we might play with the guys those who would make us being addicted to their bad habits.
As far as I,a university student,am concerned,we should have amusing activities just as an old saying goes “All work and no play makes jack a dull boy.” But at the same time,we must have these activities in a more appropriate way in that the main function of recreation is to release ourselves.
Therefore,as has been noted,how recreational activities affect us lies in the way we treat them.

There has been an upmarket trend in the tourism over the last few decades,where international travel for short breaks is common.Tourists have high levels of disposable income,considerable leisure time,are well educated,and have sophisticated tastes.There is now a demand for a better quality products,which has resulted in a fragmenting of the mass market for beach vacations; people want more specialised versions,quieter resorts,family-oriented holidays or niche market-targeted destination hotels.
The developments in technology and transport infrastructure,such as jumbo jets,low-cost airlines and more accessible airports have made many types of tourism more affordable.WHO estimates that up to 500,000 people are on planes at any time.There have also been changes in lifestyle,such as retiree-age people who sustain year round tourism.This is facilitated by internet sales of tourism products.Some sites have now started to offer dynamic packaging,in which an inclusive price is quoted for a tailor-made package requested by the customer upon impulse.
