①Sometimes working outdoors, sometimes in an office, sometimes using scientific equipment and sometimes meeting local people and tourists, I am never bored.
②Having collected and evaluated the information, I help other scientists to predict where lava from the volcano will flow next and how fast.
③Having worked hard all day, I went to bed early.
④Having experienced quite a few earthquakes in Hawaii already, I didn't take much notice.
⑤Having earlier collected special clothes from the observatory, we put them on before we went any closer.
⑥Having studied volcanoes now for many years, I am still amazed at their beauty as well as their potential to cause great damage.
⑦The other two climbed down into the crater to collect some lava for later study, but this being my first experience, I stayed at the top and watched them.
