Gas bubbles inside the magma grow bigger and try to escape as the molten rock gets closer to the Earth's surface. When the gas bubbles can't be held back any longer, the volcano erupts. Imagine ❼shaking (shake) a soda bottle until the gas inside blows the cap off, and you can understand something of how a volcano erupts.

Then the eruption is explosive.‎ Ⅱ.片段选词填空 stay in a safe place， go down， go out， take shelter， to protect yourself or your family members， trapped in， shout for help ‎ An earthquake is one of the most common natural disasters.It may cause great damage.So it is wise to learn some simple safety tips ❶to_protect_yourself_or_your_family_members.‎ During an earthquake, lie beneath an object that is not easily damaged.Do not go near objects that could directly fall on you.Never use the elevator to ❷go_down.Stay inside until the shaking stops and it is safe to go outside.Research has shown that most injuries happen when people inside buildings try to ❸go_out.Use the staircases at all times.‎ If you are outdoors, do not ❹take_shelter under a tree, streetlights, electric poles or tall buildings.If you are driving, stop your car and ❺stay_in_a_safe_place.Do not park your car under a tree or any tall object.‎ If ❻trapped_in debris (瓦砾堆), cover your mouth with a handkerchief or clothing.Tap on a pipe or wall so rescuers can find you.Use a whistle (哨子) if one is available.Never ❼shout_for_help.Shouting can cause you to breathe in dangerous amounts of dust.Do not light a match because you may burn yourself.Do not move about or kick up dust.‎ 课下作业（三） 高考语篇提能练 Ⅰ.阅读理解 ‎“Wait. You've always wanted to do that, too？！ Why don't we do it this summer？！”‎ That was how it started. My sister and I were talking on the phone when the topic of forest firefighting arose.‎ Fighting wildfires as a summer job may sound strange, but it's not uncommon in the western United States. There are at least 50,000 wildfires annually in the U．S., a high number of which happen in the western states. And of course, most happen during the hot months of the year, between May and September. So the need for people willing to spend summers fighting these fires is real!‎ Federal agencies, such as the U．S. Forest Service and the Bureau of Land Management, as well as private contractors (承包商), employ thousands of seasonal firefighters each year. Through a friend, my sister and I were introduced to one of these private contractors. He agreed to employ us for his crew if we took a training course and passed the pack test.‎ Our training consisted of a twoday course on the basics of wildfire management. We learned what causes wildfires, the tools and techniques for fighting them and safety ‎ guidelines.‎ The pack test requires a person to walk three miles in under 45 minutes while carrying a 45pound pack. Since most beginners work on Line, Engine or Hotshot Crews — all extremely physical — everyone needs to pass this test. And we did!‎ We learned that fighting forest fires includes more than simply spraying (喷出) water on flames. The goal is to contain the fire, not put it out entirely. This is done mainly with tools used to remove plants and roots from the ground, creating a line of dirt around the fire. After this, crews watch the line to ensure the fire doesn't burn more brightly. We also did “mopup” tasks — going into the burned areas and burying hot spots, such as burning tree trunks. Though firefighting is difficult and dangerous, it's definitely rewarding.‎ ‎1．What does Paragraph 3 mainly explain?‎ A．Why there's a great need for forest firefighters.‎ B．Who is the right person for the firefighting job.‎ C．When is the best time to take the firefighting job.‎ D．Why so many wildfires happen in the U．S. every year.‎ 解析：选A　段落大意题。由第三段末的“So the need for people willing to spend summers fighting these fires is real！”可知，本段是对美国需要大量夏季森林消防队员的解释。‎ ‎2．Before becoming summer firefighters, the author and his sister________.‎ A．received formal training for beginners B．got permission from the U．S. Forest Service C．had never heard any information about this job D．had a heated discussion about the safety of the job 解析：选A　细节理解题。由第四段的“He agreed to employ us for his crew if we took a training course and passed the pack test.”可知，在成为夏季森林消防队员之前，作者和妹妹接受了正规训练以及体能测试。‎ ‎3．Which of the following can best describe the pack test?‎ A．Safetyrelated.　　　　　　B．Terribly dangerous.‎ C．Recordbreaking. D．Physically exhausting.‎ 解析：选D　推理判断题。由倒数第二段的“requires a person to walk three miles in under 45 minutes while carrying a 45pound pack ... all extremely physical ...”可知，该测试极其耗费体力。‎ ‎4．What does the underlined word “contain” in the last paragraph probably mean?‎ A．Fight. B．Build.‎ C．Detect. D．Control.‎ 解析：选D　词义猜测题。由画线词后的“not put it out entirely”以及除喷水以外的救火方式“with tools ... creating a line of dirt around the fire”可知，扑救森林火灾目的其实在于控制火势，而非完全扑灭。‎ Ⅱ.阅读七选五 Polar exploration is the exploration of the lands around the North and South poles. The poles are the coldest and most remote (遥远的) places on Earth. The North Pole is in the Arctic Ocean, which is covered by a huge, floating ice sheet. __1__‎ Some early polar explorers used dogsleds (狗拉雪橇) or went on foot. This was dangerous, as huge cracks in the ice could swallow dogs, sleds, and people. Other explorers used ships. __2__ Later explorers used icebreakers, airplanes, and snowmobiles.‎ ‎__3__ Some people wanted the fame that would come from being the first to reach an unknown land. Others were hoping to discover shorter sailing routes from Europe to Eastern Asia. Still others expected to get rich. More recently, people began exploring the polar areas to gather scientific information.‎ The first outsider to reach the Arctic was probably an ancient Greek named Pytheas. __4__ By the 1500s the Dutch and the English adventured there in search of trade routes. In 1878～1879 a Swedish explorer sailed from Europe through the Arctic Ocean to the Pacific Ocean, which was called the Northeast Passage. In 1905 the Norwegian explorer Roald Amundsen became the first to sail through the Northwest Passage.‎ People first landed on Antarctica in 1895. British explorers Robert F. Scott and Ernest Henry Shackleton each led expeditions (远征) there in the early 1900s. In 1928 the U．S. explorer Richard E. Byrd set up a base on Antarctica's coast. __5__ During 1957～1958 scientists from several countries set up 50 bases throughout Antarctica for scientific research.‎ A．Explorers first saw Antarctica in 1820.‎ B．He reached Norway or Iceland in about 300 BC.‎ C．People made early polar explorations for a number of reasons.‎ D．Many explorers risked their lives trying to achieve these goals.‎ E．The South Pole is on land, in the frozen continent of Antarctica.‎ F．This also was dangerous, as floating ice could damage the ships.‎ G．Meanwhile, many countries became interested in the scientific study of Antarctica.‎ 语篇解读：本文是一篇说明文。文章主要介绍了极地探险的原因以及人类对北极和南极的探索。‎ ‎1．选E　由该空前对极地和北极的介绍可知，画线处是对南极的介绍。‎ ‎2．选F　F项中的ships与该空前的ships相呼应，且该项中的“This also was ‎ dangerous, as ...”与上文中的“This was dangerous, as ...”结构一致。‎ ‎3．选C　由该段的描述可知，C项内容“早期人们进行极地探险有很多原因”符合此处语境。‎ ‎4．选B　由该空前的“The first outsider to reach the Arctic”以及该空后的By the 1500s可知，B项内容“他在公元前300年左右到达挪威或冰岛一带”符合此处语境。‎ ‎5．选G　由该空前的“see up a base on Antarctica's coast”和该空后的“scientists from several countries set up 50 bases throughout Antarctica for scientific research”可知，G项内容“与此同时，很多国家对南极科考也产生了兴趣”符合此处语境。‎ Ⅲ.语法填空 On October 29, Hurricane Sandy hit the East Coast with serious flooding and fierce winds.‎ When the power died, the nurses in the neonatal intensive care unit (NICU) at New York University's Langone Medical Center didn't wait for the wind __1__ (stop). They moved into emergency mode __2__(immediate)．‎ Sandra Kyong Bradbury and the other nurses knew that for the 20 babies in the NICU, some of __3__ were dependent on ventilators (呼吸器), even a temporary loss of power could be deadly. __4__ (use) flashlights, they tended to each baby, checking vital signs.‎ Then came even __5__ (bad) news: With no power, the nurses would have to quickly move the babies out of the medical center, even though floodwaters covered the streets around the hospital.‎ With police officers and firefighters helping to illuminate (照亮) the stairwells, Bradbury slowly went down nine flights of stairs with __6__ fourpound baby boy wrapped in a blanket in her arms. She __7__ (repeat) to herself: Take it slow. Be __8__ (care) with every step.

We made them to share with friends and neighbors.‎ Preparation began with Daddy and the cleaning of the corn_husks (外壳). First he boiled them and left them in the water overnight. No husk passed inspection without being soft enough for folding. The next day, the rest of us got to work. My brothers and uncles were on hand for cleanup duty. And there was much to clean up as we women prepared the dough (生面团) made of corn. We also prepared the meat for the filling. The dough had to be spread evenly across the husk，and each tamale folded carefully so it would not split open during steaming.‎ According to the longstanding tradition — at least in my family — no one was allowed to leave the kitchen during the steaming. This could ruin the process. After all, no one wanted a bad tamale!‎ I thought the family tamalemaking party would go on forever, but to continue a family_tradition,_you needed to have family. Mine had changed forever. My father, two of my brothers and my uncle died in a short span of time. Mom and I spent months in a state of sad loss. At Christmas friends asked, “Are we going to get tamales this year？” Passing tamales out to friends was one of the great joys of the season, after all. But we couldn't face it. Eventually, as the years went by, people stopped asking.‎ One afternoon, just before Thanksgiving, my mother and I pushed an empty shopping cart through the supermarket. I rounded the corner into the next room and found her ‎ standing in front of a counter: packages of dough, bags of corn husks, dried spices — all the materials for a perfect tamale.“It's time，” Mom said. I knew she was right. We set aside a Saturday to spend in the kitchen, just the two of us, alone with our thoughts.‎ 注意：1.所续写短文的词数应为150左右；‎ ‎2．至少使用5个短文中标有下划线的关键词语；‎ ‎3．续写部分分为两段，每段的开头语已为你写好；‎ ‎4．续写完成后，请用下划线标出你所使用的关键词语。‎ Paragraph 1：‎ When we laid everything out I fell into the old routine.‎ ‎ ‎ ‎ ‎ Paragraph 2：‎ My mother and I pronounced our tamalemaking a success, full of loving memories from the past and hopeful wishes for tomorrow. ‎ 参考范文：‎ Paragraph 1：‎ When we laid everything out I fell into the old routine. We were for cleanup duty ourselves as we went along. Of course Daddy wasn't there to deal with the corn_husks. They hadn't been cleaned; they hadn't been in the water. We lit a candle for our relatives in heaven and got to work filling and folding the tamales. Neither of us stepped out of the busy kitchen until the steaming was complete. By the end of the day, we had many beautiful tamales to share with our neighbors and friends.‎ Paragraph 2：‎ My mother and I pronounced our tamalemaking a success, full of loving memories from the past and hopeful wishes for tomorrow. You can be sure we are preparing for this year's tamales and our kitchen will be crowded once again. My grandniece wants to learn the family_tradition. Rule One：No one leaves the kitchen during the steaming! Life may change, but our family is forever bound together by love, memories and our favorite Thanksgiving dish.‎
