【正文】 s a strong movement, these pieces will fall on the floor directly and not on you. There is a strong chance of short circuits (短路) and fire during an earthquake. Make sure you turn off electrical connections and gas immediately when an earthquake happens. 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 go 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 go out. Use the staircases at all times. If you are outdoors, do not take shelter under a tree, streetlights, electric poles or tall buildings. If you are driving, stop your car and stay in a safe place. Do not park your car under a tree or any tall object. If trapped in debris (瓦礫堆), cover your mouth with a handkerchief or clothing. Tap on a pipe or the wall so that rescuers (營救人員) can find you. Use a whistle (哨子) if one is available. Never shout 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.（1）The purpose of the passage is to tell readers . to do in earthquakes to prevent earthquakes damage caused by earthquakes rescue work after earthquakes（2）The underlined word Fragile in Paragraph 2 probably means . found broken（3）During the earthquake, people are advised to . shelter under a tree to a safe place quickly out of the building at once off electricity and gas immediately【答案】 （1）A（2）C（3）D 【解析】【分析】本文是一篇議論文，作者對于如何在地震中保護自己和家人這一問題，給出了一些簡單的安全技巧。 （1）考查推理判斷。根據(jù)第一段中的“So it is wise to learn some simple safety tips to protect yourself or your family members.”因此，學習一些簡單的安全技巧來保護自己和家人是明智的?？芍?，這篇文章的目的是告訴讀者在地震中該怎么做。故選A。 （2）考查詞義猜測。根據(jù)第二段中的“l(fā)ike those made of glass are easily broken and should usually be placed on a lower surface, near the ground instead of placing them in the cupboards higher up.”像那些玻璃做的容易破碎，通常應放在較低的表面，接近地面，而不是把它們放在較高的碗柜。可知，“Fragile”的意思是易碎的。故選C。 （3）考查細節(jié)理解。根據(jù)第三段中的“Make sure you turn off electrical connections and gas immediately when an earthquake happens.”當?shù)卣鸢l(fā)生時，一定要立即切斷電源和煤氣?？芍?，地震期間，建議人們立即關掉電和煤氣。故選D。 【點評】本題考點涉及細節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇教育類閱讀，考生需要準確掌握細節(jié)信息，同時根據(jù)上下文的邏輯關系，進行分析，推理，從而選出正確答案。7．閱讀理解 For decades, doctors have warned patients that too much salt can be bad for the heart. Heat attack has long been considered a grownup problem, but a new research suggests that salt is starting to affect children. Eating too much salty food when you39。re young can lead to health problems later. Salt is made up of two elements: sodium and chlorine. Dietary guidelines remend that adults and kids aged 9 — 13 shouldn39。t consume more than about a teaspoon of salt daily. The average American eats twice this amount. This worries doctors because too much sodium results in the body producing more blood. To pump the extra blood, the heart has to work harder. This causes a rise in blood pressure a measurement of how stressed the heart is. High blood pressure often leads to heart disease. A kid with high blood pressure is more likely to bee a grownup with high blood pressure. Reducing salt might also help stop childhood obesity (肥胖). British researchers recently found that kids who eat less salt also drink fewer sugary soft drinks. Drinking fewer fizzy drinks makes kids less likely to gain weight, bee obese and develop high blood pressure. Salt can affect more than just your heart and weight. A recent study found that a growing number of kids in the US are suffering from kidney stones. This painful condition usually affects people aged over 40. Now, kids as young as five are getting it. Cutting down on salt can be hard, but you can retrain yourself to prefer less salty food. The best way to reduce the amount of sodium you eat is to make changes gradually. Start by adding half as much salt to your dinner as you normally do. Switch to fresh foods instead of canned and bottled versions. And go easy on the condiments (調(diào)味品). You might also want to start reading nutrition labels. You may be surprised to learn that there are 1,150 mg of sodium in a double cheeseburger, and over 2, 000 mg in many frozen meals.（1）What is the author39。s major concern? eat too much salty food. adults suffer from heart attack. consume too much salt. attack is now a youth problem.（2）What does the author refer to as the cause of childhood obesity? more salty food. of physical exercise. many sugary soft drinks. the same food as the adults.（3）What is another disease tending to be younger according to Paragraph 4? . stone. disease. attack.（4）What is Paragraph 5 mainly about? laws of health. to cut down on salt. diet. amount of salt we need.【答案】 （1）A（2）C（3）B（4）B 【解析】【分析】本文是一篇說明文，介紹了鹽對心臟有影響的原因，以及人們在日常生活中保持低鹽的生活方式。 （1）考查細節(jié)理解。根據(jù)第一段中的“Heat attack has long been considered a grownup problem, but a new research suggests that salt is starting to affect children. Eating too much salty food when you39。re young can lead to health problems later. ”長期以來，心臟病被認為是成年人的問題，但一項新的研究表明，鹽開始影響兒童。年輕時吃太多咸的食物會導致以后的健康問題；以及第三段中的“A kid with high blood pressure is more likely to bee a grownup with high blood pressure.”一個有高血壓的孩子更有可能成為一個有高血壓的成年人，可知，文章作者特別擔心孩子食用過咸的食物導致心臟病和高血壓。故選A。 （2）考查細節(jié)理解。根據(jù)第三段中的“Reducing salt might also help stop childhood obesity (肥胖). British researchers recently found that kids who eat less salt also drink fewer sugary soft drinks. ”減少鹽可能有助于阻止兒童長胖。英國的研究人員最近發(fā)現(xiàn)吃鹽少的孩子喝的含糖飲料也更少，可知，作者認為吃多鹽食品和喝過多含糖的軟飲料也會使孩子長胖。故選C。 （3）考查細節(jié)理解。根據(jù)第四段中的“A recent study found that a growing number of kids in the US are suffering from kidney stones.
