     What do you do if you suddenly have the chance to visit Australia for the first time but only have one day

to spend there? Why not just stay in Sydney, I advise. You'll find you can do a lot in Australia from there. And

here's how:

     Wander along the South Circular Quay and chances are you'll come across an Aboriginal (土著居民) or

two playing a didgeridoo (迪吉里杜管) But there's not much left of the Aboriginal heritage (遗产) in Sydney.

It's a deep wound which even now remains very painful. A more exciting way to experience Aboriginal culture

is to take a trip on the Tribal Warrior, a respected old pearling lugger (打捞珍珠的小帆船). Now it is being

used as a tourist ship offering tours of Sydney Harbor. The tours, run by Aboriginals, take in some of the most

popular sights of the harbor( such as the Sydney Opera House).

      Of all the sporting heroes Australia has produced, Sir Donald Bradman is widely considered the greatest. So

it's nice to meet him-or at least a life-size model of him-face to face in the imaginative little museum within the

famous Sydney Cricket (板球) Ground. The stadium has been hosting cricket matches since the 1850s. You

can also meet ancient worthies such as Frank Spofforth and Tiger O'Reilly here.

      You really don't need to go any further than Sydney to experience the excitement of one of the country's

great national hobbies, surfing. Bondi Beach is in a suburb (郊区) of Sydney easily reachable from the center.

What a life! You can leave the office and within half an hour be out riding those waves at Bondi. Never surfed

before? Head for Lets Go Surfing, a Bondi school offering surf classes for beginners and experienced surfers

alike. If you've ever been interested in surfing, do it here.
