Maybe different people come up with different answers. However, there is no denying the fact that the only threat to humankind, apart from humankind itself, is, without any doubt, the nature.Natural disasters are the result of natural environmental processes that have a damaging effect on people. Natural disasters can come in many forms: such as geological events like earthquakes, tsunamis or mud-rock flows, climatic events like storms, hurricanes or tornadoes and fire events like forest fires and wildfires. The damage done by natural disasters is mainly as a result of our inability to predict exactly when they will happen. Although great progress has been made in designing and developing forecasting models for some natural disasters, complete certainty is still impossible. Even to be pessimistic, there is a possibility that human beings will never achieve accurate prediction of the happening of all natural disasters. What's more, even though we were able to predict these disasters from nature, preventing them is equally impossible. So we only have two ways to both prevent injuries or deaths and reduce economic losses to the least. These two methods are to prepare before a natural disaster comes to hit, and to manage the necessary resources and public services after a natural disaster strikes. These two things have always been at the leading position of the projects of both national governments and international organizations. In the United States, the Federal Emergency Management Agency (FEMA) is responsible for the “preparedness, response and recovery planning” of both man-made and natural disasters. Most natural disasters cannot be prevented, and both emergency preparation and good disaster management are the best ways to deal with them. Although natural events may appear to serve no purpose but simply to punish and destroy, natural disasters, a perfect symbol of the great power of the nature, are display of our planet's evolution and its state of change. 语篇解读：本文是一篇说明文。文章主要介绍了自然灾害是人类最大的威胁，人类面对自然灾害最佳的处理办法就是做好应急准备和良好的灾害管理。 √ 1．Which can't be regarded as a similarity between tornadoes and earthquakes?

Can animals sense earthquakes? The answer 28. _________ this question is not clear. So far, debate over 29. _________ animals can truly sense earthquakes has not solved the question. 语篇解读：本文是一篇议论文。文章主要介绍了在地震前一些动物有奇特的反应，人们把动物的这些奇怪的举止与地震联系起来。有的科学家支持这种观点，有的则认为这种联系值得怀疑，动物是否能在人之前感觉地震还没有定论。 20．behaving　考查非谓语动词。此处behave作about的宾语，about是介词，接动名词作宾语。 21．have been told　考查时态、语态及主谓一致。根据句子中的for centuries可知，此处应用现在完成时态，又因主语stories为复数且与动词tell之间是被动关系，故应填have been told。 22．who/that　考查定语从句。设空处是一个定语从句，先行词是Researchers，指人，且从句中缺主语，故应用关系代词来引导。 23．shake　考查固定搭配。feel sb./sth. do为固定用法，跟不带to的不定式作宾语补足语。 24．easier　考查形容词比较级。由句意及than可知，此处应用比较级。 25．an　考查冠词。此处表示泛指，earthquake这个单词的读音以元音音素开头，故用an。 26．doubtful　考查形容词。分析句子可知，设空处缺少表语，故应用形容词。 27．owners　考查名词复数。下文as they prefer to believe that their animals have the power of giving warnings before earthquakes中的they指的是动物的主人，故填owners。 28．to　考查介词。the answer to ...为固定用法，意为“……的答案”。 29．whether　考查连词。此处应用一个意为“是否”的词来引导句子，因前面有介词over，故此处只能填whether。 (四)主题微写作(15分) [教材原句]　①Perhaps now is the time to start planning for the future? ②Now that it's hard to avoid a disaster on Earth, perhaps I should start thinking about moving to space ... ③Well, maybe I have been worrying too much. [分析]　以上三句作者使用了perhaps, maybe来表达一种不确定的可能性，这种表达可以用于阐述个人的不是非常肯定的观点。 [仿写]　极端天气近年来已成为一个越来越令人担忧的问题。飓风是极端天气的一种形式。这些巨大的风暴形成于海洋之上，带来强风。强风会对建筑物造成严重的破坏，可能摧毁房屋。极端天气的发生往往与气候变化有关。随着地球气候变暖，这些极端天气事件的频率和强度(frequency and intensity)可能会增加，这要求我们做出更大的努力，以保护生命和财产。 ________________________________________________________ ________________________________________________________ ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ _______________________________ Extreme weather has become an increasingly concerning issue in recent years.Hurricanes are one form of extreme weather. These massive storms form over the ocean and bring strong winds. The high winds can cause serious damage to buildings, maybe destroying homes. The occurrence of extreme weather is often related to climate change. As the Earth's climate warms, perhaps the frequency and intensity of these extreme weather events can increase. This calls for our greater efforts to protect lives and property. 本课结束 更多精彩内容请登录：www.zghkt.cn $
