Unit 1 Festivals around the world using language课时作业

阅读理解

第一节 请阅读下列短文,从短文后各题所给的A、B、C、D四个选项中,选出最佳选项。

   "One thing I enjoy about my job is that I can work on something that is actually active," says Game McGimsey,an American volcanologist(火山学家).Part of his job includes keeping an eye on Alaska's many active volcanoes and giving people a heads­up when a volcano might erupt(喷发).

  Volcanoes can influence the world in ways we might not think about.For example,on Dec.15 1989,a 747 jetliner(a large airplane) flew through a thick ash cloud produced by Mount Redoubt,an Alaskan volcano that hadn't erupted in 25 years.The ash caused all four engines to die,and the plane's electronics went dead.

  "The plane was within several thousand feet of flying into the mountains below when the pilots got a couple of engines restarted and landed safely in Anchorage," McGimsey says.It cost nearly 80 million to repair the damage to the plane.

  Such situations show just how dangerous volcanoes can be.However,volcanologists know the risks and are prepared to protect themselves.

  McGimsey admits,"There is certainly a higher danger level in volcanology than some other jobs.We understand how serious the danger is,and we don't like taking unnecessary chances.We avoid getting too close to an erupting volcano,because it is not worth injury or death simply to get a rock or a photograph."
