Task5：原定的guitar课取消了 cuz lack of people.

　　1、ask a professor to teach her in private classes.can learn a lot of things effectively/ too expensive

　　2、buy some beginner books with CDs.Cheap/ but require discipline to keep on practising

　　Task6：two ways of eco-tourism

　　1、to cut the environmental cost.

　　ex：a company of eco-tourism would let tourists walk or hike to the ancient remains in the mountains in stead of taking bus.so it is pretty eco-friendly

　　2、to do some projects to preserve environment

　　ex：another company would let tourists do plant some trees in South America in which the forests are cut off.

　　in this way，they not only enjoy the scenery but also preserve the habitats of many wild animals.
