高中英语 Module 4 Sandstorms in Asia Period 1 Introduc
Module 4 Sandstorms in Asia Period 1 Introduction Reading andVocabularyA sandstorm, also known as a dust storm, is exactly what it soundslike. A very strong windstorm especially in the desert carriesclouds of sand or dust that greatly reduces visibility. This windis usually caused by convection currents(对流气流), which arecreated by intense heating of the ground, and is usually strongenough to move entire sand dunes. Air is unstable when heated, and this instability in the air will cause higher winds to mix with winds in the lower atmosphere, producing strong surface winds.Sandstorms can disturb people’s travel, and can sometimes destroy whole roads, and dry flat areas. Similar dust storms can be found on the planet Mars, and are thought to be seasonal. Today, the destruction of forests and too much farming of farmland can lead to sandstorms. Too much use of water resources can also cause sandstorms.In the United States of America, sandstorms are rare because of the lack of large deserts and more importantly the development of proper agricultural techniques. The last recorded destructive sandstorm in American history was the Dust Bowl, which occurred on July16, 1971and was widely recorded by meteorologists(气象学家).To protect themselves from sandstorms, some people wear protective suits. Special equipment can be fixed in some cars to prevent sand from getting into the engine. Sandstorms can cause coughs, and the sand and dust has also been known to carry “infectious diseases”. Sand particles, unlike dus t ones, will block air passages, and cause a person who breathes them in to choke. Dust particles may cause an allergic(过敏的)reaction.Ⅰ. Skim the passage and find the main idea quickly.____________________________________________________________答案：The passage aims to tell us the formation and damage of sandstorms.Ⅱ.

第五步：过渡衔接联成篇 Nowadays, there are many environment problems such as air pollution, water pollution and sandstorms. The polluted air does harm to people's health. The polluted water causes diseases and deaths. What's more, many animals and plants are dying out as a result of all kinds of environment problems. It is people who should be responsible for the problems. With the development of society, more cars and waste are produced and more natural resources are being used, which have made our environment worse and worse.
