参考解析
解析：第二段第一句提到“there are only three major countries in West Africa experiencing a major outbreak: Sierra Leone , Liberia and Guinea”，即埃博拉病毒主要在西非三个国家肆虐，其他国家也有埃博拉确诊病例的报道。由此可知，本段主要讲的是感染埃博拉的地区，故选D。
第三段首先提到Unless you recently visited one of the three affected West countries（除非你最近去过西非感染埃博拉的三个国家中的一个），否则你感染到埃博拉的风险是零，然后介绍了埃博拉的传播方式。所以，本段主要讲感染埃博拉的风险，故选A。
第四段主要介绍的是感染埃博拉的症状：恶心、虚弱、胃痛，不寻常的症状有胸痛、流血、或喉呢痛，以此可以判断是否可能已感染了埃博拉病毒，故选C。
第五段主要介绍的是埃博拉病毒是怎样对机体造成危害的：它会破坏人体的每一个器官，会过度刺激人体的炎症反应。故E项符合题意。
由第二段首句“…there are only three major countries in West Africa experiencing a major outbreak…”可知埃博拉疫情首先在西非的塞拉利昂、利比里亚和几内亚三个国家爆发，故选E。
由第三段第二句“Unlike other recent airborne virus outbreaks like SARS, the Ebola vi-rus can only be spread through direct contact with an infected person”可知，SARS是通过空气传播的，而埃博拉是通过直接接触已被感染的病人传播的，两者的传播方式不同，故选C。
由第四段第二句“Symptoms may appear as early as two days or as late as three weeks after initial infection”可知，感染埃博拉的症状可能最早在感染后两天或晚至三周才会显现，说明潜伏的天数不等，故本题应选F。
由第三段第三句“Specifically , Ebola is spread through contact with body fluids.”可知，埃博拉病毒通过接触被感染者的体液传播，故选A。

The 2014 Ebola outbreak is the largest in history and the first Ebola outbreak in West Africa. Although the current epidemic does not cause a significant risk to other nations, many countries, including China and the United States of America, have actually been working closely with the Ebola hit states. For example, the U.S. Centers for Disease Control and Prevention (CDC) is taking precautions at home besides its activities abroad.CDCs team of “virus hunters” is supported by specialized public health teams both in West Africa and at the CDC Atlanta headquarters. Together, they offer continuous support to save lives and protect people. CDC works closely with a number of U.S. government agencies, national and international partners. CDCs experience of working with Ebola is important to the World Health Organizations growing West Africa Ebola response.On Sept. 2, 2014, CDC Director, Tom Frieden called for more international partners to join this effort. “The sooner the world comes together to help West Africa, the safer we all will be. We know how to stop this outbreak. There is a window of opportunity to do so the challenge is to scale up the massive response needed to stop this outbreak.”CDCs response to Ebola is the largest international outbreak response in CDCs history with over 100 disease specialists on the ground in West Africa, supported by hundreds of public health emergency response experts stateside , activated at Level 1, its highest level, because of the significance of this outbreak.The CDC supports affected countries to establish Emergency Operations Centers at national and local levels and helps countries track the epidemic including using real-time data to improve real-time response.Efforts in West Africa to identify those infected and track people who have come into contact with them are improving. The CDC is operating and supporting labs in the region to improve diagnosis and testing samples from people with suspected Ebola from around the world. Local health care systems are strengthened through communication, coordination with partners and training on infection control for health care workers and safe patient treatment.26. How could we describe the 2014 Ebola outbreak?A. The first one in western countries.B. It did not ever threaten West Africa.C. Not the first but the largest one.27. The 2014 Ebola outbreak response was()?A. an American stateside activity.B. an international activity.C. a regional activity.28. What does the underlined word “massive” mean in Paragraph 3?A. huge.B. quick.C. urgent29. How many disease specialists from CDC have gone to West Africa for the Ebola response?A. Less than 100.B. A hundred.C. More than 100.30. What action does CDC take to respond to the large Ebola outbreak?A. Work closely with governmental, national and international partners.B. Call for more partners to join this effort.C. Establish Emergency Operations Centers.

共用题干第三篇Infection of AIDSAccording to a report of the World Health Organization,this year will see 2.6 million deaths from AIDS,the highest yearly international total since the disease began to take hold in the late 1970s, despite questionable antiretro-viral drugs（抗逆转录酶病毒药）that staved off AIDS deaths in the richer countries.As things stood,the number of deaths was likely to increase for many years before peaking. The report said about half of all people who acquired HIV become infected before they turned 25 and usually died before their 35th birthdays of AIDS,which destroys the body's immune methods.Although ninety-five percent of people with HIV live in the developing world,battling HIV rates was still a challenge in the developed countries of the West,where there are"very worrying facts" that safe sex practices are dropping among gays.While AIDS deaths in the United States dropped by 42 percent between 1996 and 1997,the figure dropped by only half that between 1997 and last year.The report added that in Eastern Europe and Central Asia,the number of infected people had risen by a third this year,to 360,000.This was mainly due to an increase in the use of infected needles to inject drugs in Russia and the Ukraine. More than 2,700 cases of HIV were reported in Moscow in the fitst nine months of this year.Although cases of HIV remain relatively low in the Middle East,increasing use of injected drugs accounted for two thirds of new HIV cases in Bahrian last year,half in Iran and more than a third in Tunisia.There has been an increase in the number of people infected with HIV in Eastern Europe and Central Asia mainly because__________.A:most people were infected when staying in developed countries in the pastB:there were more cases of HIV presentC:in some countries more infected needles were used for the injection of drugsD:HIV reports were written with more points in these countries
共用题干第三篇Eating Meat一Less or More?Every second in the United States alone,mnore than 250 animals are slaughtered for food,adding up tomore than 8 billion animals each year. Reducing the amount of meat in ones diet is nutritionally,environ-mentally,and ethically beneficial.People who eat meat usually have weaker immune systems compared to those of vegetarians.Meat hasbeen directly linked to diabetes,obesity,arthritis,and many other illnesses.Furthermore,meat-eaters areat a higher risk for diseases,including cancer,and they are more likely to die from these diseases.Criticssay that a meatless diet does not provide enough nutrients,especially protein and iron.Actually,accordingto A Teens Guide to Going Vegetarian,by Judy Krizmanic,protein is found in almost every food,and ironappears in many vegetables.Getting enough nutrients in a meat-reduced diet should not lie difficult.A 1988study found that some of the highest pesticide residues appear in meat and eggs.Diets including more fruitsand vegetables will only make people healthier.Some skeptics believe that there will be a shortage of food if animals are not eaten.In fact,the oppositeis true.More than 80% of the corn and 95%of the oats grown in the U.S.are fed to livestock.The worldscattle alone consume enough food to equal the caloric needs of 8.7 billion people,more than the entire hu-man population.One half of the water used in the Unites States also goes to livestock;250 gallons of waterproduces only 1 lb.（磅）of beef.

共用题干第二篇Why Not Eat Breakfast?Breakfast is not only the most important meal of the day,it is also the most neglected or skipped.Common reasons for not eating breakfast include lack of time,not feeling hungry,traditional dislike for breakfast,and dieting.Breakfast simply means"break the fast."Your body spends at least six to twelve hours each night in a fasting state.In the morning your body needs energy to rev up（转动起来）into high gear for the day's work ahead.If you skip breakfast,you are likely to concentrate less effectively in the late morning, feel irritable, short-tempered（易怒的）,tired, or weak.When you choose not to eat breakfast,your body stays in slow gear.Also,people who skip breakfast often binge（无节制地大吃）later in the day at other meals or eat a high-calorie（高卡路里）snack in the morning.Breakfast eaters tend to eat less fat during the day,have more strength and endurance and better concentration and problem-solving ability.A good breakfast should provide up to 1 /3 of your total calorie needs for the day.On the average,we eat 400 less calories for breakfast than for dinner.If breakfast doesn't appeal to you in the morning,try eating a lighter dinner earlier in the evening or save half your dinner for breakfast in the morning.If you still aren't hungry in the morning,start with something small like juice or toast or have a mid-morning snack later when you are hungry.Not eating breakfast can also cause you to overeat,since a fall in blood sugar often makes you feel very hungry later.To make matters worse,since your body is in a slowed state,it will not be able to burn those extra calories very efficiently.If you feed your body healthy snacks and meals throughout the day,you are less likely to become extremely hungry and stuff yourself as soon as you begin to eat.Since breakfast is the first and most important meal of the day,choosing the right fuel is important.The best breakfast foods are fruits,juice,lean meat,and grain products such as breads,rice,noodles,and cereals.The word"fast"in the phrase"break the fast"in paragraph 2 meansA:"a series of quick actions".B:"a habit of eating".C:"a strict rule".D:"a period of not eating".

单选题Although many people would not believe it, the mosquito is actually the most dangerous animal in Africa. While the bite of the black mamba is invariably lethal when untreated, this dreaded snake kills only a few dozen people per year. Hippopotami, with their immense strength and foul dispositions, kill hundreds of people per year in rivers and lakes, but the mosquito is still more dangerous. Mosquitoes bite hundreds of millions of people in Africa every year, and they infect over a million each year with malaria, a disease that is often fatal. Which of the following questions would be most useful in evaluating the claim made above regarding the mosquito?ACould a person survive an attack by a black mamba if that person received prompt medical attention?BWhat criteria are used to determine which animal is the “most dangerous” animal?CCould the incidence of mosquito bites be decreased through the judicious use of pesticides and insect repellent?DDoes malaria kill more people per year in Africa than tuberculosis?EHow does the percentage of people who survive hippopotamus attacks in Africa each year compare with the percentage of people who survive mosquito bites?
