Module 4 Sandstorms in Asia 沙尘暴是指强风将地面上的大量尘沙卷入空中,使空气特别浑浊,水平能 见度低于 100 米的天气现象。在古今中外的历史上有哪些严重或恐怖的沙尘暴 呢? A short history of sandstorms How often do you think about sandstorms? Maybe not very often.But here we are going to see a few famous sandstorms out of many throughout history. Australia, September 22nd, 2009 This one was cruel because it made Australia look like another planet in an entire week.It looked like that the photos documenting the sandstorm were edited by someone who was severely color blind.The entire southern continent was painted orangered, but people still tried to go about their day as if 5 million tons of dust hadn't blown through their respiratory system. Pakistan, July 4th, 2007 On this day, a sandstorm swept through the nation and shocked everyone with its hazy blinding sheets of sand.Everyone thought it'd be over within a day.However, it poured for several days , displacing homes and flooding people to death.Temperatures ranged from 131 F during the day to 30 F at night and about 200 people died because of this sandstorm. North America, 19301935 Farmers were very disappointed about this one.During the 1930s, North American regions from New Mexico to Saskatchewan underwent serious sandstorms before World WarⅡ.This was known as “The Dust Bowl” and it struck right around the time of the Great Depression.If you ask your elderly friends about it, they'll probably have something interesting to say.Let me give you an idea of how exhausting and annoying the sandstorm was: winds reached up to 60 mph, and it lasted for FIVE YEARS. 1.document v. 2.respiratory system 3.shock v. 4.hazy adj. 5.displace v. 6.undergo v. 记录 呼吸系统 使人震惊 模糊的 移走 遭受 Fill in the blanks according to the passage. 1.The sandstorm which happened in Australia, on September 22nd, 2009 lasted_________ days. 2.About ________ people died after the sandstorm which happened in Pakistan, on July 4th,2007. 3.The wind of “The Dust Bowl” reached ____________ mph. 4.Niya, China, is actually referred to as “ ________________” because of the sandstorm. 【答案】 1.seven 2.200 3.60 4.Pompeii of the Silk Road 编后语 ? 有的同学听课时容易走神,常常听着听着心思就不知道溜到哪里去了;有的学生,虽然留心听讲,却常常“跟不上步伐”,思维落后在老师的讲解后。这两种情况都 不能达到理想的听课效果。听课最重要的是紧跟老师的思路,否则,教师讲得再好,新知识也无法接受。如何跟上老师饭思路呢?以下的听课方法值得同学们学习: ? 一、“超前思考,比较听课” ? ? ? 什么叫“超前思考,比较听课”?简单地说,就是同学们在上课的时候不仅要跟着老师的思路走,还要力争走在老师思路的前面,用自己的思路和老师的思路进行对 比,从而发现不同之处,优化思维。 比如在讲《林冲棒打洪教头》一文,老师会提出一些问题,如林冲当时为什么要戴着枷锁?林冲、洪教头是什么关系?林冲为什么要棒打洪教头??????? 老师没提了一个问题,同学们就应当立即主动地去思考,积极地寻找答案,然后和老师的解答进行比较。通
