waves, floods, volcanoes, super typhoons, blizzards (暴风雪), landslides (山崩) and droughts killed at least a quarter million people in 2010. more people were killed worldwide by natural disasters this year than have been killed in terrorism (恐怖主义) attacks in the past 40 years combined.“it just seemed like it was backtoback like waves，” said craig fugate, who heads the us federal emergency management agency. it handled a record number of disasters in 2010.“the_term_100year_event_really_lost_its_meaning_this_year.”poor construction and development practices conspire (共同导致) to make earthquakes more deadly than they need be. more people live in poverty in vulnerable (脆弱的) buildings in crowded cities. that means that when the ground shakes, the river breaches (决口), or the tropical cyclone (热浪) hits, more people die.the january earthquake that killed well more than 220,000 people in haiti is a perfect example. portauprince has nearly three times as many people many of them living in poverty and more poorly built shanties than it did 25 years ago. so had the same quake hit in 1985 instead of 2010, total deaths would have probably been in the 80,000 range, said richard olson, director of disaster risk reduction at florida international university.climate scientists say earths climate also is changing thanks to manmade global warming, bringing extreme weather, such as heat waves and flooding.white house science adviser john holdren said we should get used to climate disasters or do something about global warming：“the science is clear that we can expect more and more of these kinds of damaging events unless and until societys emissions (排放) of heattrapping gases and particles are sharply reduced.”语篇解读：2010年死于地震、热浪、洪灾、火山喷发、超强台风、暴风雪、山体滑坡和干旱的人数超过了25万人。科学家和灾难专家们认为大部分灾难都是人类自己造成的。1according to the passage, which of following statements is false?athe number of people killed by natural disasters is larger than that of people killed in terrorism attacks in 2010.bmans behaviors cause natural disasters worse than before.cwe should try to reduce the emissions of heattrapping gases and particles to avoid global warming.dthe number of people killed in terrorism attacks is larger than 250,000 in the past 40 years in 2010.解析：选d。细节理解题。根据第二段，2010年死于自然灾害的人数是25万，超过过去40年来死于恐怖主义袭击的人数的总和。2the underlined word “extreme” in the seventh paragraph means _.agreat bverycexceptional doutermost解析：选c。词义猜测题。根据下文的such as heat waves and flooding可以推断，该词大意为“异常的，罕见的”。3the sentence “the term 100year event really lost its meaning this year.” means _.apeople dont understand the meaning of the term “100year event”b“100year event” cant be described as the severity of natural disasterscnatural disasters has happened, so many people understand the meaning of “100year event”dthe term “100year event” is so easy to understand that it neednt be explained.解析：选b。句意理解题。根据前面三段可知，有太多的自然灾害发生在2010年，它们的危害超过了以往，“百年一遇”不足以说明自然灾害的危害性了，所以“百年一遇”一词也失去了其原有的意义。4what caused more than 220,000 deaths in the haiti earthquake?apoor construction. bno forecast.cpoverty. dslow aids.解析：选a。细节理解题。根据第五段可知，低劣的建筑质量和开发行为加大了地震的杀伤力。第六段第一句提到造成22万多人死亡的海地地震就是一个典型的例子。因此房屋质量差导致海地地震伤亡严重。福建专用a篇同安徽、河南专用bhawaii has become the second us. state to have discovered an outbreak of locally acquired dengue fever (登革热). florida has been combating its own local outbreak since september 2009. the hawaii department of health reported on march 24 it had discovered two cases and suspected two more. since then, kgmb (a television station for the state of hawaii) reports four confirmed and 12 suspected cases.florida saw 85 locally acquired cases in 2009 and 2010.dengue fever and its far more serious variant (变种), dengue hemorrhagic (出血的) fever, are transmitted from patient to patient by the bite of a mosquito. it is reported that the asian tiger mosquito and the yellow fever mosquito are the two primary carriers for the illness in the united states. both mosquitoes are highly adapted to living around humans and are day feeders. the asian tiger mosquito has even evolved into a slower rate of beating its wings, which reduces the whine or hum typically noticed by people when mosquitoes are near.the hawaii outbreak is centered around pearl city on the island of oahu. the florida outbreak has been confined to the key west area with one case in broward county and another in miamidade.dengue is caused by one of four related viruses. there is a vaccine for one of the four. it is possible to catch each of the viruses since infection with one does not produce immunity for the others. it appears that initial infection, or the injection of the dengue vaccine, makes the patient significantly more susceptible (易受感染的) to dengue hemorrhagic fever.5what would be the best title of the passage?atwo serious fevers in hawaiibdengue fever outbreak hits hawaiicdeadly fever adaptationsdtwo dangerous mosquitoes解析：选b。主旨大意题。由本文的首句我们可以看出，本条消息主要讲述的是登革热开始袭击美国的第二个州。6the underlined word “transmitted” in the second paragraph means _.aspread bvariedcgrew dformed解析：选a。词义猜测题。根据上下文我们可以推测，“传播；扩散”这个词义较符合短文的逻辑。7which of the following can we infer from this text?adengue hemorrhagic fever is more easily spread among humans.bonly two kinds of mosquitoes carry diseases in the world.cdengue fever outbreak is mainly found in key west area in hawaii.dthe asian tiger mosquito is less easily discovered by humans.解析：选d。推理判断题。根据第二段最后一句的内容，我们可以知道，亚洲虎蚊 (asian tiger mosquito) 在飞行的过程中，翅膀震动的速度很慢，产生的声音很小，因此不容易被人发现。8from this text we know that _.adengue vaccine makes the patient suffer from dengue hemorrhagic fever more easilybso far only one vaccine has been developed to cure dengue feverca person who suffers from dengue fever harm his immune systemdit is becoming more and more dangerous for humans to live in this world解析：选a。细节理解题。由本文的最后一句我们可以知道，如果感染了登革热，则非常容易感染登革出血热。.选做题任务型读写(安徽专用)american public education has changed in recent years. one change is that increasing numbers of american parents and teachers are starting independent public schools called charter schools.in 1991, there were no charter schools in the united states. today, more than 2,300 charter schools operate in 34 states and the district of columbia.575,000 students attend these schools. the students are from 5 years of age through 18 or older.a charter school is created by groups of parents, teachers and community members. it is similar in some ways to a traditional public school. it receives tax money to operate a number of students. the charter school must prove to local or state governments that its students are learning. these governments provide the school with the agreement, or the charter that permits it to operate.unlike a traditional public school, however, the charter school does not have to obey most laws governing public schools. local, state or federal governments cannot tell it what to teach.each school can choose its own goals and decide the ways it wants to reach those goals. class sizes are usually smaller than in many traditional public schools. many students and parents say teachers in charter schools can be more creative.however, state education agencies，local educationgoverning committees and unions often oppose charter schools. they say these schools may receive money badly needed by traditional public schools. experts say some charter schools are doing well while others are struggling.congress provided 200 million dollars for establishing charter schools in the 2006 federal budget. but, often the schools say they lack enough money for programs.many also lack needed space. district officials say they have provided 14 former school buildings for charter education. yet charter school supporters say officials should try harder to find more space.charter schools in america(1)_charter schools

schools，offices and factories. broadcasters on radio and television often use them.how did the expression begin? no one seems to know it，_1_“it grew，”he says，“because rocket scientists probably are the most intelligent people around.”not everyone would agree. some people might be considered more intelligent than rocket scientists, for example, a person who speaks fifteen languages, or a medical doctor who operates on the brain. still, many people would agree that there is something special about scientists who build rockets._2_moving pictures from before world war showed a man named buck rogers landing on the planet mars. he was a hero who could withdraw any enemy (敌军) from outer space. the rocket scientist is a different kind of hero._3_rocket scientists, however, can have problems
