What are the biggest problems that society will have to deal with in the new age? There re diseases like AIDS and cancer. There's climate change, of course. And what about producing enough cheap food and energy for the world's growing population? Who's going to solve all these terrible problems? Yes, politicians and world leaders will have a big part to play. Yes businesses will need to create the economic wealth to pay for some of these things. But who's going to make a much greater difference to something like AIDS or climate change. It's going to be a scientist. It is the scientist who can turn some new bit of science into a new technology to solve these problems. If you like thinking about the world around you, why not become a scientist? It doesn't mean you have to wear a white coat and plastic glasses and spend all your time in a lab as most people often imagine! Scientists do all kinds of amazing things that are actually interesting!

    Military scientists develop not only new weapons but new military technologies that could help make wars out of date. Forensic(法医的) scientists work with the police to find quite small clues to catch criminals. Scientists work in schools and colleges as the teachers and professors who will train tomorrow's scientists. Don't think a scientist is far away! Maybe you like cooking? You could be a food technologist helping to keep fruit and vegetables fresher for longer. Perhaps sport is your thing? Do you know that most top athletes work with sports scientists in order or improve their performance? You could even be the science writer who gets to spend the life studying the latest advances and sharing them with the world.

    Looking for something to do for the rest of your life? My advice? Take a long and hard look at science. It is interesting and ever.

    Why do so many tourists come to Easter Island? Because it has world-famous stone statues (雕像) . These statues, whose likenesses look like humans with huge stone cylinders（柱状物）balancing on their heads like hats, have tourists coming from all over the world. The tourists come to see these works of ancient art carved by the early inhabitants of the island. They come to see the mystery that has puzzled historians for decades.

    Easter Island is located in a remote part Of the South Pacific Ocean about 2,300 miles west of Chile. Easter Island covers just 45 square miles and its Polynesian name is Rapa Nui.

    On Easter Sunday 1722, a Dutch explorer named Jacob Roggeveen was the first European to see Easter Island. The early Polynesians carved the statues within the holes of the volcano (火山) using only stone tools. Then they moved these huge statues to various destinations throughout the island. These 600 statues range in height from 10 to 40 feet. Some of them weigh as much as 50 tons. How could the early Polynesians lift hundreds of heavy statues out of the volcano? How did they move them across the island to their various locations? All of these questions, as well as many others, remain unanswered.

    The early islanders probably worshiped (崇拜) these eyeless giants until sometime around 1670. In 1680, a war broke out between two groups of islanders. The victors（胜利者）of the war and ancestors of the present inhabitants, broke down many of the statues. In most cases, they broke the necks of the statues.

    Now 15 of the statues on Easter Island have been repaired to their original positions on their stone platforms. Even today, using modern tools and machinery, putting up such large statues and balancing cylinders on top of their heads presents a challenging task.
