We thought science and technology would cure all the ills of humanity, leading to lives of fulfillment and opportunity for all. However, as we have gained a deeper appreciation of the range of threats facing us, from epidemic (流行病) flu to climate change, we might even tend to assume that humanity has little future to look forward to. 课时作业(一) 19 Yet such depression is misplaced. The fossil record shows that many species have existed for millions of years—so why shouldn't we? Take a look at our species in the universe, and it becomes clear we have an excellent chance of surviving for tens of thousands of years. Look up Homo sapiens (智人) in the “Red List” of threatened species of the International Union for the Conversation of Nature (IUCN), and you will read: “Listed as Least Concern because the species is widely distributed, adaptable, currently increasing, and there are no major threats resulting in an overall population decline.” 课时作业(一) 20 So what does our deep future hold? Many researchers and organizations are now thinking seriously about the question. The potential evolution of today's technology is complicated, so it's perhaps best left to science fiction writers and futurologists to explore the possibilities of the bright future. 课时作业(一) 21 Our future is quite rosy because it shows many promising possibilities of achievement. Besides, we are now knowledgeable enough to reduce risks that threatened the existence of earlier humans and to improve those to come. Take a longer view and we can say with considerable assurance that the past holds the key to the future: by analyzing the past, we can make evidence-based forecasts about the situations in which our descendants (后代) will find themselves. 篇章导读：本文是一篇议论文。文章从几个方面论述了人类的未来是光明灿烂的。 课时作业(一) 22 1．According to the passage, what inspired our visions of the future in the past? A．The desire for lives of fulfillment. B．The belief in equal opportunity. C．The deep appreciation of threats. D．The faith in science and technology. 答案：D　细节理解题。根据第一段第二句可知，对科学技术的信仰在过去激发了我们对未来的憧憬。故选D。 课时作业(一) 23 2．What does the underlined word “rosy” in the last paragraph probably mean? A．Dangerous. B．Annoying. C．Hopeful. D．Undisturbed. 答案：C　词义猜测题。根据最后一段第一句中“because it shows many promising possibilities of achievement(因为未来充满希望)”可知，画线词“rosy”的意思是“有希望的”。故选C。 课时作业(一) 24 3．What should we do to ensure the future of mankind? A．Explore our planet's abundant resources. B．Draw upon our experience from the past. C．Build our ambition to reshape history. D．Increase the population of the world. 答案：B　细节理解题。根据最后一段最后一句可知，从更长远的角度来看，我们可以相当肯定地说，过去掌握着未来的钥匙：通过分析过去，我们可以对我们的后代将要面临的情况做出基于证据的预测。由此可知，我们应该借鉴我们过去的经验来确保人类的未来。故选B。 课时作业(一) 25 4．Which of the following would be the best title for the text? A．The Bright and Promising Future of Mankind B．Science and Technology Connected with Humans C．The Fully and Highly Evolved Human Species D．Different Researches Conducted on Our Future 答案：A　标题判断题。根据第一段第一句和最后一段第一句可知，文章讲述的是人类光明灿烂的未来。所以A项是最佳标题，故选A。 课时作业(一) 26 Ⅲ　应用文写作 假如你是李华，你所在班级要举行一次关于UFO的演讲比赛，你精心准备决定参赛，请写一篇演讲稿，内容如下： 1．UFO是世界十大未解之谜之一； 2．首次目击报告在1878年的美国； 3．大量关于UFO的图书出版和开设课程。 注意：1.写作词数应为80左右； 2．可以适当增加细节，以使行文连贯。 课时作业(一) 27 ﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍ 课时作业(一) 28 [精彩范文] Dear Sir or Madam， I am honored to be here to introduce some materials about UFO. UFO, which is short for Unidentified Flying Object, has long been regarded as one of the top 10 unsolved mysteries in the world. The first UFO sighting was reported to have happened in America in 1878. Since then, numerous sightings have been reported all over the world, many of which turned out to be false. Some people think UFOs are spaceships from other planets, others believe that they're just a kind of natural phenomenon and still others guess they're aliens.a Now about one third of the countries in the world are doing research on UFOs, about which many books and journals have been published, and in some universities courses are even set up to study UFOs.
