Sometimes working outdoors, sometimes in an office, sometimes using scientific equipment and sometimes meeting local people and tourists, I am never bored. Although my job is occasionally dangerous, I don't mind because danger excites me and makes me feel alive. However, the most important thing about my job is that I help protect ordinary people from one of the most powerful forces on earth - the volcano.,Paragraph1,,bore vt. 使……感到厌烦;n. 令人厌烦的人或物,麻烦 Tom Blair’s speech bored most of the audience.布莱尔的讲话使大部分的观众感到厌烦。 【想一想】英语中有部分及物动词,如bore, tire, excite, surprise, interest, worry, astonish, shock, frighten, terrify, disappoint, satisfy, inspire, encourage, puzzle等,它们的v.-ing形式adj.表示主体名词令人有某种感受,而它们的v.-ed式adj. 表示主体名词本身有某种感受。 【练一练】 ①He __________________ the same thing every day. ②He ______ by talking for hours about his new car. 他大讲他的新车使我们感到厌烦。 ③Mr Smith, of the speech, started to read a novel.

My job is collecting information for a database about Mount Kilauea, which is one of the most active volcanoes in Hawaii. Having collected and evaluated the information, I help other scientists to predict where lava from the volcano will flow next and how fast. Our work has saved many lives because people in the path of the lava can be warned to leave their houses. Unfortunately, we cannot move their homes out of the way, and many houses have been covered with lava or burned to the ground.,Paragraph2,,appoint vt. 任命,委派;约定,指定,安排[归纳拓展] ①)They have appointed a new headmaster at my son’s school. ②They appointed him (as) captain of the English team. ③The time appointed for the meeting was 10∶30. [即境活用] 我们在考虑指定他当秘书。 We are considering ________ ________ ________ act as secretary.,appointing him to,,When boiling rock erupts from a volcano and crashes back to earth, it causes less damage than you might imagine. This is because no one lives near the top of Mount Kilauea, where the rocks fall. The lava that flows slowly like a wave down the mountain causes far more damage because it buries everything in its path under the molten rock. However, the eruption itself is really exciting to watch and I shall never forget my first sight of one. It was in the second week after I arrived in Hawaii. Having worked hard all day, I went to bed early. I was fast asleep when suddenly my bed began shaking and I heard a strange sound, like a railway train passing my window. Having experienced quite a few earthquakes in Hawaii already, I didn't take much notice. I was about to go back to sleep when suddenly my bedroom became as bright as day. I ran out of the house into the back garden where I could see Mount Kilauea in the distance. There had been an eruption from the side of the mountain and red hot lava was fountaining hundreds of metres into the air. It was an absolutely fantastic sight.,Paragraph3,,The day after this eruption I was lucky enough to have a much closer look at it. Two other scientists and I were driven up the mountain and dropped as close as possible to the crater that had been formed during the eruption. Having earlier collected special clothes from the observatory, we put them on before we went any closer. All three of us looked like spacemen.We had white protective suits that covered our whole body, helmets, big boots and special gloves. It was not easy to walk in these suits, but we slowly made our way 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, I stayed at the top and watched them.,Paragraph4,,(1) It is/will be +时间段+before从句 “要过多久才……”before 从句用一般现在时 (2)It was +时间段+before从句 “过了多久才……”before 从句用一般过去时 (3)It won’t be +时间段+before从句 “不用过多久就会……”before 从句用一般现在时 (4)It wasn’t +时间段+before从句 “没过多久就……”before 从句用一般过去时 (5)It is +时间段+since从句 “自……以来已有多久了”,since从句中用一般过去时 Eg.
