I. Read the following paragraph carefully and answer the questions below it (4 ms)  

Adventure Tourism

     (1) Adventure tourism is a different way for tourists to see New Zealand. (2) This type of tourism uses the plentiful nature resources – mountains, rivers, lakes, wilderness areas and historical sites to provide adventure, thrills and challenges which are low risk but highly in excitement, for example, the coastal areas in New Zealand are great for canoeing and kayaking. (3) White-water rafting are another popular water adventure tour. (4) However, if you would rather keep your feet on the ground, New Zealand has over one hundred developed walkways in addition to the tracks in the twelve national Parks. (5) Surely the government will have to address this problem urgently, especially if the problem is widespread. (6) Because more and more tourists are interested in learning about New Zealand by doing exciting and unusual activities, adventure tourism will continue to grow.
