After a roll⑪ call confirmed⑫ that all were safe and sound⑬，they relaxed，laughing，crying and hugging⑭ each other.[5] [3]句中the moment后面接从句，表示“一……就……”。 [4]句中现在分词短语covering their heads with their hands在句中作方式状语。 [5]本句为主从复合句；句中含有after引导的时间状语从句；that引导宾语从句作confirmed的宾语；laughing，crying and hugging each other为并列的现在分词短语作伴随状语。 ⑦signal /ˈsɪɡnəl/ vi.& vt.发信号，示意；标志 n.信号，暗号；标志；信号灯 ⑧exit /ˈeksɪt；ˈeɡzɪt/ vi.& vt.出去，离去，退场；退出 n.出口，通道；离开 ⑨orderly /ˈɔːdəli/adj.有秩序的；有条理的，整齐的 ⑩stair /steə(r)/ n.楼梯；梯级 ⑪roll /rəʊl/ n.名单；卷；一管；翻滚 vt.& vi.翻滚，滚动；翻身；卷起roll call 点名 ⑫confirm /kənˈʃɜːm/ vt.证实，确认；使确信；批准 ⑬safe and sound 安然无恙的 ⑭hug /hʌɡ/ vt.拥抱，搂抱；抱紧 地震停止的瞬间，布朗女士意识到这是他们逃出教室的最好时机。她示意学生们抱着头，排好队，有序离开教室。只用了1分20秒的时间，全班下楼，跑到了操场上。很快，其他班级的学生们也到了。点名确认所有人都安然无恙后，他们才放松下来，笑啊，哭啊，互相拥抱着。 　　“We practise earthquake safety procedures⑮ twice a year，” said Miss Brown，“so the kids were calm enough to protect themselves during the earthquake.” ⑮procedure /prəˈsiːdʒə(r)/ n.程序，步骤，手续 “我们每年进行两次地震安全流程演习，”布朗女士说，“所以孩子们在地震时都足够镇定，能够保护自己。” Girl saves 100 from tsunami By Jessie Cable 21 December NEWDALE—On 20 December，a series of huge waves caused by an undersea earthquake raced across the ocean near Goldshore and left thousands dead.[6] Goldshore Beach was the only local beach to survive the disaster without any loss of life.[7] A 10-year-old girl， Sabrina Andron，helped around 100 people escape danger with her knowledge of tsunamis⑯. [6]句中caused by...为过去分词短语作后置定语，修饰waves；left thousands dead为“leave ＋sb./sth.＋宾语补足语”的结构，表示“使某人某物处于某种状态”。 [7]句中动词不定式to survive the disaster作后置定语，修饰beach，名词前面有the only或者形容词最高级等词修饰时，多用不定式作后置定语。 ⑯tsunami /tsuːˈnɑːmi/ n.海啸 女孩在海啸中拯救百人 杰西·凯布尔 12月21日 纽代尔——12月20日，由海底地震引起的一排排巨浪急速冲过金海岸附近的海面，造成数千人死亡。金海岸海滩是当地唯一躲过灾难，没有生命伤亡的海滩。一个10岁的女孩——萨布丽娜·安德龙，用她的海啸基础知识帮助了约100人避开危险。 　　The day began like any other on Goldshore Beach.People were walking，running or simply sitting on the sandy beach，enjoying the warm sea air and the soft wind that brushed their hair.Sabrina was one of the happy tourists until she noticed something odd⑰.“The water was like the bubbles⑱ on the top of a beer，” she later explained. “It wasn’t calm and it wasn’t going in and then out.It was just coming in and in and in.” Sabrina had just learnt about tsunamis in a Geography lesson.It immediately occurred⑲ to her that these were signs of an approaching tsunami.[8] [8]it为形式主语，代替that引导的真正的主语从句；it occurred to sb.that...表示“某人突然想到……”。 ⑰odd /ɒd/ adj.奇怪的，怪异的；偶尔的；不成对的 ⑱bubble /ˈbʌbl/ n.泡，气泡，泡沫 ⑲occur /əˈkɜː(r)/ vi.发生，出现；存在于occur to被想到，浮现在脑中 那天刚开始金海岸像往常一样。人们在沙滩上散步、奔跑或只是坐着，享受着温暖的海洋空气以及那拂过他们头发的温柔的海风。萨布丽娜是这些快乐的游客中的一个，直到她注意到了一些奇怪的现象。“海水的泡沫非常多，就像啤酒表面的泡泡，”她之后解释道，“海水不平静，不是涌来又退去，而是涌来，涌来，又涌来。”萨布丽娜刚在一堂地理课上了解到海啸。她立刻意识到这些是海啸来临的征兆。 　　Sabrina was frightened，but she soon kept her head⑳.She warned her parents of the danger，though at first they just thought she was joking.[9] However，Sabrina was certain that a terrible disaster was on its way and kept asking her parents to talk to a safety officer.To her great relief㉑，the officer immediately realized the coming danger.The beach was rapidly cleared of people，just before the huge waves crashed into the coast. [9]本句是一个主从复合句；though引导让步状语从句。 ⑳keep one’s head(在困境中)保持冷静 ㉑relief /rɪˈliːf/ n.宽慰，轻松；减轻，消除；救济 萨布丽娜害怕了，但她很快冷静下来。她提醒父母有危险，尽管起初他们以为她在开玩笑。然而，萨布丽娜确定一场可怕的灾难即将来临，她坚持要他们去找安全员谈谈。使她大为宽慰的是，这名安全员立即意识到了即将到来的危险。就在巨浪袭击海岸之前，沙滩上的人群被迅速撤离。 Read the text quickly and fill in the following blanks with suitable words. spared from injured reaction procedures signs was safety of crashed Read the text carefully and choose the best answers. 1.Why did Miss Brown open the classroom door quickly when the floor began to shake？ A.

Daily tasks Collect the elephants at 6：30 a.m. Take them to look for food in the forest. Clean the enclosure. Swim with the elephants in the lake in the afternoon. If volunteers want to relax after work，they can watch satellite television. How this vacation helps If these elephants hadn’t been rescued，they would still be living on the streets of Bangkok. A rural environment is much better for them than an urban environment where there is lots of pollution. Gorilla Safari Countries：Kenya，Rwanda，Uganda Departures：August-December，2-3 departures per month Extras：gorilla permit ￡220 If you’re lucky，you’ll see lions，elephants and rhinos on safari. The highlight of the trip is the opportunity to see gorillas in the mountain forests. However，you must be in good health-if a gorilla caught a cold，it would be extremely harmful to its whole family. How this vacation helps There are only about 600 mountain gorillas left in the world as human activity has reduced the area where they can live. When you buy a permit，this will pay for the protection of the national park. Polar Bear Watching Country：Canada Departures：sixty trips between October 1-November 19 Every October and November，groups of polar bears gather in Hudson Bay. As they are normally lonely creatures，this is unusual. The bears wait for the ocean to freeze so they can hunt seals，so this is the perfect opportunity to see them. How this vacation helps If the Arctic ice cap melts due to global warming，polar bears will be in danger. We give a share of our profits to the Polar Bears Alive Charity. Your comment These awesome bears get all the liquid they need from their food. [语篇解读]　本文是一篇应用文。文章针对几个保护野生动物的活动做了简单的介绍。 1.What will an elephant volunteer do？ A. Take food for elephants at 6：30 a.m. B.

At least three people were confirmed killed in the accident early Saturday in the Channel Islands’ port capital St. Helier，following a suspected gas leak. 　　“We have three confirmed deaths and it’s fair to say we expect to find more，” police chief Robin Smith told a news conference，saying that around 12 residents remained unaccounted for. “It is with sadness that I am confirming that the search-and-rescue operation has been moved to a recovery operation，” he said. 　　The phase involved a “painstaking search of the debris (残骸)” which could take weeks，Smith said，adding that a gas leak was the “likely” cause. Aided by sniffer dogs and experts from southern England，Jersey emergency workers had searched the rubble (瓦砾) overnight. 　　Fire chief Paul Brown confirmed that firefighters were called out to investigate the smell of gas on Friday evening，more than seven hours before the explosion. But in vain. He admitted that something had gone “horribly wrong”，considering the subsequent disaster，but insisted that Jersey islanders could still have confidence in his service. 　　Jersey’s gas supplier，Island Energy，said it was working with the fire service to understand what happened. 　　Like many others in St. Helier，Jersey’s Chief Minister Kristina Moore said she was awoken by the explosion. “Across the island you could hear this extraordinary sound，” she told the BBC. “It’s unthinkable news，so we’re all absolutely shocked and really worried about the people who are involved and about those whose lives have been lost.” 　　The incident capped a tragic week for Jersey，whose economy relies on banking，tourism and fishing. “We must call on the collective strength of the island community，” Moore said. [语篇解读]　本文是一篇新闻报道。文章主要介绍了泽西岛上一次爆炸事故后的搜救与调查工作，以及事故发生后各部门负责人对事故的表态。 4.What’s the possible cause of the accident？ A. The gas leak. B. The gas supplier. C. The recovery operation. D. The unexpected explosion. 4 5 6 7 答案：A 解析：细节理解题。根据第一段的following a suspected gas leak和第三段的a gas leak was the“likely” cause可知，燃气泄漏可能是导致爆炸事故的原因。故选A项。 5.What was the main task of the recovery operation？ A. Rescuing the dead. B. Searching the rubble. C. Searching for the debris. D. Working with fire service. 4 5 6 7 答案：C 解析：细节理解题。根据第三段第一句“The phase involved a ‘painstaking search of the debris’”可知，下一阶段的工作主要是在废墟中寻找残骸。故选C项。 6.What may Paul Brown’s words imply？ A. He had predicted the explosion hours before it. B. The fire service was investigating the explosion. C. People lost confidence in the island’s fire service. D. The fire service was partly responsible for the accident. 4 5 6 7 答案：D 解析：推理判断题。根据第四段的“He admitted that something had gone ‘horribly wrong’，considering the subsequent disaster”可知，考虑到后续发生的灾难，他推测消防部门在爆炸前几个小时对燃气气味的追踪调查中肯定有工作上的失误，因此对这起事故也间接负有一定的责任。故选D项。 4 5 6 7 7.How did Moore feel after the accident？ A. Panicked and frightened. B. Relieved and hopeful. C. Astonished and concerned. D. Fearful and sorrowful. 4 5 6 7 答案：C 解析：细节理解题。根据文章第六段的“‘ Across the island you could hear this extraordinary sound，’she told the BBC. ‘It’s unthinkable news，so we’re all absolutely shocked and really worried about the people who are involved... ’”可知，Moore认为这一事件是难以想象的，她和其他人都很震惊，并担心事故的受害者和遇难者。故选C项。 4 5 6 7 C 　　On May 7th，1902，on the island of Martinique，Ludgar Sylbaris，the town’s drunk and troublemaker，got thrown into prison.However，it turned out to be the luckiest day of his life. 　　Saint Pierre on Martinique was at the time known as the Paris of Caribbean.It had a big population of 30，000 people and was a cultural centre.Martinique is home to Mount Pelee，one of the most active volcanoes in the world. 　　In the weeks before Ludgar Sylbaris was thrown into prison，the volcano on the island of Martinique was showing signs of volcanic activity.Without modern Volcanology，people still sensed that something was going to happen，but they didn’t have a really good sense of how big or how dangerous the threat was.Thousands of people left the countryside and came to the city of Saint Pierre because they thought it would be safer there.That was a terrible mistake. 　　The day after Ludgar Sylbaris went into that prison cell，Mount Pelee exploded.And in an instant 3，000 people were killed.A pressure wave flattened every single building.Anyone who was unlucky enough to be outside was instantly burned to death.Those who were in shelter found themselves choking as their lungs were burned from the inside out.There was really no escape except for one person，Ludgar Sylbaris. 　　The cell he was in had been built as an armory (军械库).So it had been built within the thick walls and it happened that the only opening in it faced away from the eruption.Even so，super-hot air began to force its way underneath the door.And as his cell heated to extremely high temperatures，he was forced to take off his clothes，push them underneath the door and he peed (小便) on the clothes just to try to keep the hot air from entering.He was still badly burned and wasn’t found until four days later when rescuers heard his cries. [语篇解读]　本文是一篇记叙文，主要讲述了一个真实的历史事件——1902年培雷山火山爆发的灾难。 8.What caused so many people to die in the volcano eruption？ A. Shortage of survival skills. B. Ignorance of modern Volcanology. C. Lack of good judgement of the threat. D. Unawareness of the volcanic activity signs. 8 9 10 11 答案：C 解析：细节理解题。根据第三段中的“Without modern Volcanology ... dangerous the threat was.”可知，尽管人们意识到了火山活动的迹象，但由于缺乏现代火山学知识，他们未能准确判断情况的严重性，导致误判和错误的应对措施。这反映了他们对火山威胁的判断力不足。故选C。 8 9 10 11 9.Which of the following is the right order according to the text？ a.The volcano of Mount Pelee erupted. b.Buildings were flattened and no one escaped. c.Thousands of people fled to the city of Saint Pierre. d.Mount Pelee was showing signs of volcanic activity. e.Ludgar Sylbaris managed to save himself and was rescued. A. dbace　　　　　　　　　 B. abdce C. adceb D. dcabe 8 9 10 11 答案：D 解析：细节理解题。文章第三段中的“the volcano on...of volcanic activity”对应d；然后提到“Thousands of people...city of Saint Pierre”，对应c；第四段中的“Mount Pelee exploded.”对应a；然后提到“A pressure wave...instantly burned to death.”，对应a；最后一段“He was still...heard his cries.”对应e。所以文章先提及培雷山的火山活动迹象，然后是人们逃往圣皮埃尔市，接着是火山爆发，之后是建筑被毁和人员的伤亡，最后是Ludgar Sylbaris的生还。正确的顺序是 dcabe。故选D。 8 9 10 11 10.Which of the following is true according to the last paragraph？ A. The cell’s opening faced the eruption. B. The cell was far away from the eruption. C. Ludgar took proper self-rescue measures. D. Ludgar hid in the heavily-guarded armory. 8 9 10 11 答案：C 8 9 10 11 解析：细节理解题。根据最后一段中的“Even so，super-hot...air from entering.”可知，Ludgar Sylbaris 在极端环境下采取了脱衣服、塞门缝，并在衣服上小便的方式来避免热空气的伤害，这些行为属于适当的自救措施。故选C。 11.What’s the purpose of the text？ A. To introduce the island of Martinique. B. To inspire people to explore the Mount Pelee. C. To provide ways to survive a volcano eruption. D. To tell the story of a volcano eruption survivor. 8 9 10 11 答案：D 解析：推理判断题。 通过阅读全文可以看出，文章按照时间顺序讲述了培雷山火山爆发的故事，并重点讲述了Ludgar Sylbaris作为幸存者的故事。文章的目的是讲述一个火山爆发幸存者的故事。故 选D。 8 9 10 11 Ⅱ.阅读七选五 　　The number of people dying in natural disasters is lower today than it was in the past. 　1　 However，if you can keep your head and find the right place to stay when the ground starts shaking，you might be able to survive. 　2　 The biggest danger is falling pieces.Since earthquakes happen suddenly without warning，you have to think quickly to stay safe.If you are indoors during an earthquake，remember：“drop，cover and hold on.” 　　Drop：When you feel the ground shaking or something crashing，get down on your hands and knees. 　3　 Quickly crawl (缓慢行进) under a strong desk or table nearby.Don’t try to run downstairs or walk to a safer place because you might fall.If you are in bed，stay there and cover your head with a pillow until the shaking stops. 　　Cover：Use one hand to cover your neck and head. 　4　 If not，move towards a wall inside the building，not the outside walls with windows.Stay on your hands and knees，keeping your hand over your neck for protection. 　　Hold on：Hold onto your desk or table with one hand while keeping the other over your neck and head.Be ready to move with the desk or table. 　5　 However，if you are outside，driving or at the beach，trying to find something to hide under may not be an option. A. This keeps you from falling over. B. If it is not strong enough，turn to another one. C. Earthquakes can still be destructive，though. D. Then crawl under a desk or table if there’s one close by. E.Advanced technology provides many ways for us to stay safer. F.Remember，don’t try to move until the shaking has completely stopped. G.The safest place during an earthquake is likely an open field with no trees around. [语篇解读]　本文是一篇说明文，介绍了地震中安全逃生的方法。 1.答案：C 解析：根据上文“The number of people...was in the past.(如今死于自然灾害的人数比过去要少)”以及下文“However，if you...be able to survive.(然而，如果你能保持头脑清醒，并在地面开始摇晃时找到合适的地方，你就有可能挽救自己的生命)”可推知，C项承接上下文，构成转折关系，符合语境。故选C。 2.答案：G 解析：根据下文“The biggest danger...‘drop，cover and hold on.’”可知，本段开始讲地震的时候在室外怎么做，然后再引出地震时在室内怎么做，并引出下文。G项与第二段最后一句照应。故选G。 3.答案：A 解析：上文“When you feel...your hands and knees.”告诉我们感到震动时要趴下；选项A承接上文，说明趴下的好处，符合语境。故选A。 4.答案：D 解析：根据下文“If not，move...walls with windows.”可知，设空处与下文都是在假设情况，且设空处陈述“如果有……”时的做法； D项里面的if从句与下文的“if not”照应，该项中的“crawl under a desk or table”与上一段中“Quickly crawl under a strong desk or table nearby.”相呼应。故选D。 5.答案：F 解析：根据上文“Hold on：Hold onto...the desk or table.”可知，本段主要说明了地震的时候抓住物体，不要移动。F项与本段小标题“Hold on”一致，故选F。 $$
