as she unwrapped the gift from her best friend，Susan．“I...I thought you could use it for something．” Susan's stammered explanation did nothing to help us understand why a twelve-by-eighteen-inch dark blue carpet remnant(零料) was being presented as a birthday gift． 课时学案 课时分层作业 Period 6　 My heart went out to my daughter．The murmured “thanks” was barely hearable and she laid the piece of carpet on the kitchen counter，and the two girls headed outside to play with the family dogs． The next morning，I carried a bag of kitchen rubbish outside．My heart hurt as I lifted the lid of the trash can and saw Susan's carpet lying among the other discarded items．Hesitating for only a moment，I reached in and took it from amid the junk．After a light brushing，I brought it into the house and put it in the hall closet． 课时学案 课时分层作业 Period 6　 Without mentioning Susan's name for nearly three weeks，Holly came home with an invitation of Susan's birthday．Although her voice carried a so-what attitude，I sensed she was pleased by the invitation．The following day，I drove Holly to Susan's home．At the end of the road，we saw a tall woman wearing a shapeless sweater over navy blue pants standing in the doorway to greet us as we approached the small farmhouse．It must be Susan's mom．“Excuse the mess，” she apologized，holding the door open while we threaded our way through stuff that seemed to be everywhere．Then，Susan's mom waved a hand toward the kitchen counter，which was barely visible through the mix of medicines．“This is my medicine cabinet，” she explained． 课时学案 课时分层作业 Period 6　 Susan led us through the house．It seemed to be alive with four-legged fur kittens roaming underfoot and sprawling across the backs of the dirty sofa and chairs．She proudly showed us her room，which was decorated with used furnishings．After eating a simple homemade birthday cake，we offered our thanks for the visit and said goodbye． 课时学案 课时分层作业 Period 6　 注意：1．续写词数应为 150 左右； 2．请按如下格式作答。 Holly sat quietly in the

【文章大意】　本文话题为友情类。霍莉最好的朋友苏珊送给她一块深蓝色的地毯作为生日礼物。霍莉很困惑，但还是说了声谢谢。第二天，霍莉的妈妈在垃圾桶里看到了地毯，并把它保存了起来。几个星期后，霍莉被邀请到苏珊家参加苏珊的生日聚会。苏珊家里乱糟糟的，全是旧家具。霍莉和妈妈吃完自制的生日蛋糕后道别回家。 课时学案 课时分层作业 Period 6　 【写作指导】 1．段落续写：①由第一段首句“回家的路上，霍莉静静地坐在车里”可知，第一段可描写霍莉意识到扔掉苏珊送的地毯是不对的行为，决定去垃圾桶里找回来。 ②由第二段首句“把车开进车库后，我走了进去，朝门厅的壁橱走去”可知，第二段可描写妈妈拿出地毯，霍莉流下了泪水，地毯成为全世界最珍贵的生日礼物。 2．续写线索：回家路上一言不发——垃圾桶里寻找地毯——妈妈归还地毯——霍莉流下泪水——认识到礼物的珍贵 课时学案 课时分层作业 Period 6　 [参考范文] Holly sat quietly in the car on the way home． Stealing a glance，I noticed her back was straight．Her head and shoulders were thrust forward as if willing the car to move faster．No sooner had we come to a stop in the driveway than she pushed open the car door and walked purposefully toward the side gate．Curious，I shifted into park and followed．A lump caught in my throat as I observed my daughter standing next to the trash can peering inside．Her shoulders sank as she replaced the lid and dragged herself into the house． 课时学案 课时分层作业 Period 6　 After pulling the car into the garage，I went inside and headed for the hall closet． By this time，Holly was sitting at the kitchen table staring out the window as if her heart were stolen．“Is this what you were looking for？” I placed the piece of carpet on the table in front of her．She jumped from the chair with astonishment．“Thanks，Mom．” A tear or two slipped from her eyes and splashed onto the dark blue remnant that，as if by magic，had become the most precious birthday present in the whole world． 课时学案 课时分层作业 Period 6　 Ⅰ．阅读理解 A Wherever we humans go，we leave behind a mess．That goes for space，too．An estimated 500，000 pieces of debris (碎片) litter the Earth's orbit as a result of man's exploration of space．Some satellites have been hit by fast-moving pieces of junk．The remains of old rockets can be the size of a bus，while other pieces of debris are simply tiny spots of paint． 课时分层作业(六) Period 6 33 Today，our species is responsible for the junk dashing around Earth at high speed，and if we don't start actively removing the largest pieces，the risk of collisions will only increase．“Imagine how dangerous sailing the high seas would be，if all the ships ever lost in history were still floating on top of the water，” says Jan Wörner，the ESA's director general．“That is the current situation in orbit，and it cannot be allowed to continue．” 课时学案 课时分层作业 Period 6　 It's almost as if we need a truck to remove all of the failed satellites from our orbit．By 2025，the agency plans on launching the world's first orbiting junk collector，a four-armed robot that tracks down space waste．The first-of-its-kind task，known as ClearSpace-1，is collecting only a single piece of space junk to prove the concept works．The target in this case is called Vespa，a leftover from the ESA's Vega rocket launched in 2013．This piece of junk weighs roughly the same as a small satellite and has a simple shape that should make it easy to grab it with four robotic arms．Once it's safe in the arms of the garbage collector，it will then be dragged out of orbit and allowed to burn up in the atmosphere． 课时学案 课时分层作业 Period 6　 In addition，an Australian company，Electro Optic Systems，has received a $3.5 million government fund to develop the world's first laser tracking (激光跟踪) technology．It will replace existing radar (雷达) networks that monitor that part of space．The goal is to track small objects with great accuracy． 【语篇解读】　本文是一篇说明文。文章介绍了人类的太空垃圾清理计划。 课时学案 课时分层作业 Period 6　 1．Why does Jan Wörner refer to ships on the high seas? A．To explain the danger of space debris． B．To describe the universe's huge space． C．To praise man's exploration of space． D．To compare the oceans with the universe． √ A　[推理判断题。根据第二段中的“Imagine how dangerous sailing...be allowed to continue．”可知，Jan Wörner用公海上的船只来解释太空碎片的危险。故选A。] 课时学案 课时分层作业 Period 6　 2．Humans plan to handle debris by ________． A．ClearSpace-1 and Vespa B．the ESA's Vega rocket and radar networks C．the orbiting junk collector and the first laser tracking technology D．a truck that can remove all the failed satellites and track small objects √ C　[细节理解题。根据第三段中的“By 2025，the agency plans...tracks down space waste．”及最后一段中的“In addition，an Australian company...track small objects with great accuracy．”可知，人类计划通过轨道垃圾收集器和首项激光跟踪技术来处理太空垃圾。故选C。] 课时学案 课时分层作业 Period 6　 3．What can be a suitable title for the text? A．Dangerous Space Exploration B．Cleaning Up Space Junk C．Developing Space Technology D．Launching a Four-armed Robot √ 课时学案 课时分层作业 Period 6　 B　[标题归纳题。根据第一段中的“Wherever we humans go，we leave behind a mess．That goes for space，too．(人类所到之处都是一片狼藉，太空也不例外)”及下文对太空垃圾清理计划的介绍可知，本文主要介绍了人类的太空垃圾清理计划。由此可知，B项(清理太空垃圾)适合作为本文标题。] 4．Where is this text probably from? A．An astronomy report． B．A travel guidebook． C．Science fiction． D．An environmental magazine． √ D　[文章出处题。通读全文可知，本文主要介绍了人类的太空垃圾清理计划。由此可知，这篇文章可能来自一本环保杂志。故选D。] 课时学案 课时分层作业 Period 6　 B The surface of Mars is etched(蚀刻) with ancient river valleys and lake basins．Some researchers think that liquid water once flowed on the Red Planet．Today，Mars is too cold for much，if any，liquid water to exist．And 3.8 billion years ago，when the flowing water formed，the Sun was fainter than it is today，making it even harder to imagine a warm Martian climate．That's why many researchers think Mars may have gone in and out of deep freezes． 课时学案 课时分层作业 Period 6　 Some researchers have suggested that early Mars only melt when large asteroid impacts or volcanic eruptions temporarily warmed the planet．But Kasting，a geologist at Pennsylvania State University，thinks warm windows from such dramatic events would have been too brief to carve the vast valleys that exist on Mars．Now，Kasting and his colleagues have come up with an alternative explanation：They think Mars may have experienced a series of climate cycles caused by changes in the strength of the greenhouse effect． 课时学案 课时分层作业 Period 6　 The idea goes like this：When Mars was cold and frozen，volcanoes continued to erupt the greenhouse gases carbon dioxide and hydrogen into the atmosphere．There，the gas blanket trapped heat and warmed the planet up until liquid water began to flow，forming Mars' rivers and lakes．However，warm temperatures and abundant water would also have sped up certain chemical reactions that consumed carbon dioxide，mitigating the greenhouse effect and cooling the planet back down again．Then the cycle would repeat． 课时学案 课时分层作业 Period 6　 Kasting shared his theory with other astronomers at the December meeting of the American Geophysical Union in San Francisco，and in the journal Earth and Planetary Science Letters．So far，Kasting's team has only shown that such an explanation is possible．But the researchers say field trips could help test the idea by looking for evidence of multiple warm events，and their duration． 【语篇解读】　本文是一篇说明文。火星上曾经有液态水，那它是怎么形成的呢？科学家们提出了新的猜想。 课时学案 课时分层作业 Period 6　 5．What made researchers believe that liquid water once existed on Mars? A．The color of the planet． B．The geological features of Mars． C．The temperatures of the Sun． D．The natural climate of Mars． √ B　[细节理解题。根据第一段前两句可知，火星的地质特征，即表面存在古老水道蚀刻的痕迹，让研究人员认为火星上曾经有液态水。故选B。] 课时学案 课时分层作业 Period 6　 6．Which idea may Kasting agree with? A．Large asteroids had no impact on Mars． B．Volcanic eruptions were very frequent on Mars． C．There were no carbon dioxide and hydrogen on Mars． D．The vast valleys on Mars couldn't be formed in a short time． √ D　[细节理解题。根据第二段第二句可知，Kasting认为，突发事件带来的温暖期太过短暂，不足以形成火星上巨大的峡谷。故选D。] 课时学案 课时分层作业 Period 6　 7．What does the underlined word “mitigating” in paragraph 3 mean? A．Reducing．　　 B．Imitating． C．Predicting． D．Enhancing． √ A　[词义猜测题。根据画线词前半句可知，高温和充足的水分加速了二氧化碳的消耗，二氧化碳的减少就会减缓温室效应，从而使火星温度下降。所以mitigating为“减少，减缓”之意。故选A。] 课时学案 课时分层作业 Period 6　 8．Which of the following might confirm Kasting's theory? A．The publication of the journal． B．The future Mars missions． C．The design of the climate model． D．The cooperation with astronomers． √ B　[推理判断题。根据最后一段最后一句可知，研究人员认为，未来的火星任务进行的实地考察或许可以发现气候反复变暖的证据来帮助证明这个理论。故选B。] 课时学案 课时分层作业 Period 6　 Ⅱ．应用文写作 假定你是李华，上周五的夜晚在回家的路上偶遇了外星人。请你给好朋友Tom写一封邮件告知他此事。 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。 课时学案 课时分层作业 Period 6　 ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ 课时学案 课时分层作业 Period 6　 [参考范文] Dear Tom， I'm writing to tell you something about my encounter with an alien． Last Friday，I was walking home at about 11 pm when I found a huge round object flying in the sky．After a few seconds，it landed on the ground in front of me．To my great astonishment，an alien walked out of it．The alien had one big eye，four arms and four legs．Just at that moment，the alien noticed me and disappeared with its UFO． 课时学案 课时分层作业 Period 6　 $$
