Ebola Outbreak
1. You are likely aware that several countries in West Africa are battling an Ebola outbreak.Eb-ola is a dangerous and often lethal viral infection.Scientists believe that humans contracted the vi-rus by eating the meat of rare animals.It is now believed that bats are the primary carries of the virus。
2. To date,there are only three major countries in West Africa experiencing a major outbreak: Sierra Leone,Liberia and Guinea. However,other countries such as Nigeria have reported con-firmed cases of Ebola within their borders.
3. Unless you recently visited one of the three affected West countries you risk of contracting the virus is virtually zero.Unlike other recent airborne virus outbreaks like SARS,the Ebola virus can only be spread through direct contact with an infected person.Specifically,Ebola is spread through contact with body fluids .Though the virus is transmittable,only an infected person exhib-iting symptoms is communicable.
4. The signs and symptoms of Ebola are non-specific and patients typically exhibit them after a week of contracting the virus.Symptoms may appear as early as two days or as late as three weeks after initial infection.Symptoms include disgust,weakness and stomach pain.More uncommon symptoms include chest pain,bleeding and sore throat.
5.Ebola is devastating because of its ability to attack and replicate in every organ of the body. This causes an overstimulation of the body's inflammatory response,causing the flu-like symp- toms. The virus also causes bleeding and impairs the body's normal clotting mechanism（凝血机制）,making bleeding even more severe .Loss of blood volume and decreased organ perfusion（器官灌注）ultimately lead to organ failure and death.
6. The current outbreak is the deadliest viral outbreak in over 35 years.While diseases such as the malaria（疟疾）are far more communicable,Ebola is one of the world's most fatal viral infec- tions .Ebola's fatality rate exceeds that of SARS.

The difference between SARS and Ebola viruses lies in
A:.infected body fluids
B: against the outbreak severity
C: the mode of transmission
D: the initial days of being infected
E:.three countries in West Africa
F: within a wide range of days

考题 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.

考题 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

考题 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".
