baby elephants.Apparently the older elephants can play a kind of football!Dad:I admit that sounds rather fun.Rachel,is this holiday near the coast?Rachel:Yes,it is.Dad:Then lets meet in the middle.As a compromise,how about we stay nearby in a nice hotel?You can do some ecotourism activities while I lie on the beach and read a book.Then were both happy.Rachel:So I can look after elephants?OK then,I agree,but we both have to go on a one-day bike tour of the jungle.Dad:Fine,its a deal.P67 Activity8 Complete the passage with the expressions in the box As tourism develops,people are becoming
