It was not easy to walk in these suits, but we slowly made our way\s\up1(29(29) to the edge of the crater and looked down into the red, boiling centre. The other two climbed down into the crater to collect some lava for later study, but this being my first experience\s\up1(30(30)， I stayed at the top and watched them.

　　Today, I am just as enthusiastic about\s\up1(31(31) my job as the day I first started. Having studied volcanoes now for many years, I am still amazed at\s\up1(32(32) their beauty as well as their potential\s\up1(33(33) to cause great damage.

　　就在这次火山喷发的第二天，我很有幸作了一次更近距离的观察。我和另外两位科学家被驱车送上山，到最靠近这次火山喷口的地方才下车。早先从观测站出发时就带了一些特别的安全服，于是我们穿上安全服再走近火山口。我们三个人看上去就像宇航员一样，我们都穿着白色的防护服遮住全身，戴上了头盔和特别的手套，还穿了双大靴子。穿着这些衣服走起路来不容易，但我们还是缓缓往火山口的边缘走去，并且向下看到了红红的沸腾的中央。另外两人攀下火山口去收集供日后研究用的岩浆，我是第一次经历这样的事，所以留在山顶上观察他们。

如今，我和当初从事这项工作时一样满怀热情。虽然我现在从事火山研究很多年了，但是我对火山的壮丽景色以及它们那潜在的巨大破坏力仍然感到惊愕不已。
