Lesson 67 文本   Volcanoes  Haroun Tazieff the Polish scientist, has spent his life-time studying active volcanoes and deep caves in all parts of the world. In 1948, he went to lake Kivu in the Congo to observe a new volcano which he later named Kituro. Tazieff was able to set up his camp very close to the volcano while it was erupting violently. Though he managed to take a number of brilliant photographs, he could not stay near the volcano for very long. He noticed that a river of liquid rock was coming towards him. It threatened to surround him completely, but Tazieff managed to escape just in time. He waited until the volcano became quiet and he was able to return two days later. This time, he managed to climb into the mouth of Kituro so that he could take photographs  and measure temperatures. Tazieff has often risked his life in this way. He has been able to tell us more about active volcanoes than any man alive. 文本解析 一）词汇学习Word study say与tell，这两个词都有“说”的含义，但在用法上有区别。 1.
