Lots of students know what a marathon (马拉松赛跑) is, but perhaps they don't know what a triathlon is. The triathlon is a sport that has three parts-swimming, bicycling and running. It is not an easy sport, but a man named Joe Salter is very good at it. A few months ago, he finished a special triathlon—he juggled (抛起接住) three balls all the time during the triathlon. That is to say, he kept on throwing and catching three balls while he was swimming, riding a bicycle and running.
31-year-old Joe is from Florida, the USA. He loves juggling and he started at the age of 8. Joe did well in juggling. Later, he got the idea to do a triathlon and juggle at the same time to make it more fun. Many juggling fans laughed at his idea and thought it was just a joke. But Joe didn't give up and he kept practising it. Because of his hard work, he made it at last.
Talking about his triathlon, Joe said swimming was the hardest part. "It was difficult and complex(复杂的)," he said. "I basically only used my legs, so it took quite a lot of work. Also, swimming in open water made it a little harder. It was not like in a pool."

Just 28 years ago, Berlin was a city divided into two by the Berlin Wall. How excitedpeople were as the Berlin Wall came down. Since then, Berlin has become one of the coolest cities in Europe. Here are the main reasons why I think Berlin is cool.
First, Berlin has cheap hotels and everyday objects (物品). You needn't worry aboutspending too much money when visiting Berlin.
Second, Berlin knows how to give parties, and there is a festival here every month ofthe year. Perhaps the most famous is the Berlin International Film Festival (the BIFF).
Third, Berlin has beautiful buildings of its own. The Brandenburg Gate is one of thecity's most famous buildings. It's the symbol (象征) of more than 200 years of history. The TV Tower is as good as the Eiffel Tower in Paris and the London Eye.
Lastly, Berlin is a city of living art. Artists can create works of art on the sides ofbuildings.
If you want to visit a European city with culture, cheap objects and lots of colours,Berlin is the place to be. What are you waiting for? Get to Europe's coolest city before anyone else discovers it
