Last year,we spent Christmas and New Year in Queensland,Australia.The beaches there were beautiful,and we spent a lot of time playing by the sea,swimming and surfing.One day,we were on a beach just south of a city called Cairns.My little sister was looking for shells in the sand down near the waves when she shoutedto me,"Hey,Lan!Look what I've found!" I ran down to have a look,and saw her pointing at a strange black object that was half buried (掩埋) in the sand,"What is it?" she asked.I said I didn't know.Just then,my father came over,"Are you enjoying yourselves,you two?" he asked.Then he saw the strangeblack thing."What's that?" he said,bending down to take a closer look.Suddenly,he said,"Quick kids,get awayfrom here.Go and play somewhere else." We went and played further down the beach,while Dad ran up to the shop near the beach to make a phone call.About 20 minutes later,we heard the noise of cars and trucks arriving,and a lot of soldiers ran onto the beach.They told everyone to leave the beach and stay away from it.About half an hour later,we were sitting with Dad in a café a few hundred metres from the beach,whenwe heard an enormous explosion (爆炸)."What was that?" we asked Dad."That was the thing you found," he said."One of the soldiers down there told me it was a Japanese bomb (炸弹) from World War II.Sometimes they get washed up on the beaches here求全文翻
