听力原文: Camping Holidays
To many people, camping seems to be an ideal way of spending a holiday. / Not only is it cheaper, / it can also be far more convenient and enjoyable. / If you have young children, / camping has particular advantages. / There is always plenty for them to do, / and they enjoy the freedom of camping compared to the discipline of staying in a hotel. / Above all, camping provides a complete change for everyone,/and afterwards you return refreshed to your normal way of life. /
To some people, however, all these advantages are outweighed by the disadvantages. / Such people will point out that on a camping holiday the mother still has to cook for everyone. / What is worse, she has to prepare meals / without the help of all the equipment in her kitchen at home. / Under bad weather, there may be too many flies and mosquitoes. / For these people a holiday in a hotel is well worth the extra expense.
