[A] worthwhile in the long run.
[B] liable to continue regardless of the great cost.
[C] bound to settle the problem once and for all.
[D] wasteful in view of the few victims of the disease.
正确答案：A
54.A【精析】该题为推理题。根据第四段第三句和第四句“But the Feds say their efforts have kept West Nile from doing far more dam- age.‘We're basically building the infrastructure to deal with this o— ver the next 50 years，’says Dr. Lyle Peterson,a CDC epidemiolo- gist.”我们知道，联邦调查局认为他们所做出的努力防止了西尼罗河病毒造成更大的损失，而且他们正在建设基础设施为未来50 年的病毒预防做出准备，因此，我们可以推断出，联邦政府认为他们为预防病毒蔓延所作出的努力在长远来说是值得的，故A项正确；文中没有提到联邦调查局可能会继续为控制西尼罗河病毒投入资金以及将会彻底解决西尼罗河病毒蔓延事件，故不选择B、C 项；D项是流行病学家而非联邦调查局的观点，故不选。 -

It’s clear that success and failure are important and common topics. Every business has its ups and downs, and so does every person. In other words, sometimes we succeed and sometimes we fail.

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答案：C解析：第二段中提到埃博拉病情爆发的几个地点：Sierra Leone, Liberia and Guinea，几个地名提示，本题答案为D。
第三段第一句“Unless you recently visited one of the three affected West countries you risk of contracting the virus is virtually zero.”告诉我们，你如果并未到达疫情爆发地点，那么你患病几率为0，因此得知答案为A（我是否可能遭遇病毒）。
第四段第一句“The signs and symptoms of Ebola are non-specific and patients typically exhibit them after a week of contracting the virus.”便提及了埃博拉病毒的患病症状，故可知答案为C（我如何知道我是否患病了）。
第五段第一句话“Ebola is devastating because of its ability to attack and replicate in every organ of the body.”告诉了我们埃博拉病毒的致病机理。故本题答案为E（埃博拉病毒堆积造成什么样的影响）。
由第一段第一句话“You are likely aware that several countries in West Africa are battling an Ebola outbreak.”可知，埃博拉病毒爆发于西非的几个国家。故本题选E。
由题干中的SARS可定位到第三段，其中“Unlike other recent airborne virus outbreaks like SARS,the Ebola virus can only be spread through direct contact with an infected person.”提示，答案为C(它们的传播方式不同）。
由第四段的“Symptoms may appear as early as two days or as late as three weeks after initial infection.”一句可知，潜伏期为二到三周不等，故本题选F。
根据第三段的“Specifically, Ebola is spread through contact with body fluids.”可知，体液的接触是主要传播途径。故本题选A。 -

单选题The number of speakers of English in Shakespeare’s time is estimated (估计) to have been about five million. Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language as well as various levels of usage that are employed both in its spoken and written forms. In fact, it is impossible to estimate the number of people in the world who have acquired an adequate (足够的) working knowledge of English in addition to their own languages. The purpose for English learning and the situations in which such learning takes place are so varied that it is difficult to explain and still more difficult to judge what forms an adequate working knowledge for each situation. The main reason for the widespread demand for English is its present-day importance as a world language. Besides serving the indefinite needs of its native speakers, English is a language in which some of important works in science, technology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport communications, international conferences, and the spread of information over the radio and television networks of many nations. It is a language of wider communication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal communication in such matters as government, commerce, industry, law and education as well as for international communication and for entrance to the scientific and technological developments in the West.Which of the following statements is NOT trueASome 260 million people in the world have an adequate working knowledge of English.

52.C 【精析】该题为细节题。第二段第四句“Federal. health officials are still trying to figure out why, but say they may be finding more West Nile precisely because they're on the lookout for it.”中的“be on the lookout for something”意为“注意，留心，警戒”，由此我们知道，联邦公共卫生官员仍然在寻找病毒蔓延的原因，但是认为因为他们对病毒的警惕性高，因此才可能会发现更多的感染者。故只有C项的表述正确。 -
第14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.
CDC's 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. CDC's experience of working with Ebola is important to the World Health Organization's 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.”
CDC's response to Ebola is the largest international outbreak response in CDC's 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. urgent
29. 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.

Examining historical and modern species records from Singapore and neighboring Malaysia, researchers found that Singapore has lost 95% of its native forest habitat and nearly 28% of its overall biodiversity since 1819, when the British established a colony on the island. Today, more than half of Singapore’s surviving species are concentrated in just one-quarter of a percent of the country’s total area, in land designated as forest reserves.
