高三英语单项填空中等难度题查看答案及解析

The virus “Ebola” is named after the Ebola River in what is now the Democratic Republic of the Congo. That’s where the virus was discovered in 1976. A person can only get Ebola through direct contact with an infected person’s bodily fluids, for example, sweat or spit. Additionally, the virus can get into your body through your eyes and mouth if those areas come into contact with something that contains the bodily fluids of an infected person. That’s why health care workers are supposed to keep themselves completely covered while treating patients.

The deadliest Ebola outbreak is spreading fast in Western Africa, taking over 900 lives so far. The health systems in Guinea, Sierra Leone and Liberia are severely lacking in resources, and health care workers may not have access to adequate protective clothing when working in rural clinics, where the proper protections are lacking. Since Guinea, Sierra Leone and Liberia share a border; it’s easier for people to move from one country to another, increasing the risk for disease spread.

For now, all doctors can do is treat the symptoms and provide supportive care like monitoring heart rate, blood pressure, and breathing while making sure the patients’ fluids are supplied. Sometimes patients are given antibiotics(抗生素) to treat other possible infections. The hope is to make the patient pull through the infection so their immune system can eventually clear the virus. The people who survive Ebola have created enough antibodies to kill it.

There are several promising drugs and vaccines in development, but since Ebola is less common—and research about it is not well funded — there is no drug or vaccine that has been approved for use in humans. Many of the other drugs and vaccines have not yet been tested in humans. The WHO (World Health Organization) is meeting next week to discuss whether experimental treatments should be used during this outbreak.

1.According to the passage, Ebola only spreads through _________.

A. patients’ sweat　　　 B. bodily fluids

C. people’s spit　　 　　 D. your body

2.Which is the possible reason why Ebola spreads in West Africa quickly?

A. The Ebola river is polluted by the virus.

B. There aren’t any protections.

C. The protective clothing is adequate.

D. Three western countries share a border.

3.Why have there been no cures used for Ebola in humans so far?

A. There are not enough drugs for the infected people.

B. Ebola is rare and its research money is lacking.

C. The people have enough antibodies to kill Ebola.

D. The WHO has decided not to use them.

4.Which of the following can be the best title?

A. The Prevention from Ebola.

B. No Cure for the Virus “Ebola”.

C. The Deadliest Ebola in Africa.

D. Introduction to the Virus “Ebola”.

Controlling the Ebola virus outbreak at the source in West Africa is the most effective way to decrease international risk of transmission, according to a research paper.

If the epidemic(时疫) persists and grows, it's likely there will be more cases(病例) of the deadly virus exported to other countries, including Canada, via air travel, said Dr. Kamran Khan, a physician and researcher at St. Michael's Hospital.

Dr. Khan, who examines global airline travel patterns to predict the spread of diseases, said that every month, three Ebola-infected travellers are likely to leave West Africa, which is experiencing a widespread outbreak of the virus -- and this number would only increase as the epidemic grows.

Dr. Khan and his co-authors said it is essential that other countries, their public health agencies and hospitals should be prepared. The risk of international spread would be further _____ if this epidemic were to take hold in other countries, especially those with weak public health systems.

"The international community must be mindful and be ready to support the early detection and control of cases." Dr. Khan said.

Dr. Khan noted that of the almost 500,000 travellers who flew on commercial flights out of Guinea, Liberia or Sierra Leone in 2013, more than half were headed to destinations in five countries: Ghana (17.5 per cent, Senegal (14.4 per cent), the United Kingdom (8.7 per cent, France (7.1 per cent) and Gambia (6.8 per cent). More than 60 per cent of travellers from those countries in 2014 are expected to have final destinations in low- or lower-middle income countries.

"Given that these countries have limited medical and public health resources, they may have difficulty quickly identifying and effectively responding to imported Ebola cases”, said Dr Khan.

1.How does Dr. Khan predict the spread of diseases?

A.By doing experiments

B.By examining global airline travel patterns

C. By setting up a model

D. By collecting the data of the cases

2.We can fill in the blank in Paragraph 4 with _____.

A. decreased　　 B. increased

C. avoided　　 　 D. predicted

3.In low income countries, ______.

A. it is easy to identify imported Ebola cases

B. people have rich medical resources

C. imported Ebola cases may not be effectively responded to

D. travelers are not allowed to go to some places

2014 saw that the Ebola virus reappeared in Guinea and soon spread into neighbouring Liberia and Sierra Leone, killing over 7,800 people by the new year of 2015. It leads to viral hemorrhagic fever, which is characterized by high fever and internal bleeding etc.

Ebola is named after the Ebola River, where it was first discovered in 1976. There are five different types of the Ebola virus, each named after where they first happened: Sudan, Ivory Coast, Reston, Bundibugyo, and Zaire. The deadliest of the five, Zaire, was responsible for the 2012 out- break, and is believed to be attacking Guinea.

Ebola is naturally found in fruit bats, which pass on the virus to other animals by biting or sucking on their blood. Humans who are suffering from the Ebola infection might have touched the bodily fluids of the infected animals. Once infected, a human becomes a carrier of the deadly virus.

Unfortunately, there are no disease - specific treatments for Ebola. Health - care workers only supply the infected people with physiological saline（生理盐水）to keep them in good condition. Ebola can kill 90% of those infected, especially in underdeveloped societies like those in Africa. Since there have been many cases of nurses catching the disease from patients, they are forced to wear strict protective clothes, and in some cases, not even allowed to get close to the infected. The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control.

What’s worse, since we live in an interconnected world, where the situation in one country can affect us all, the influences of Ebola are huge: damaging trade relations, affecting foreign visitors, and weakening entire countries. It is feared that the disease may spread throughout west African countries. For every country, a strong health system can decrease the risk of health attack and lessen the impact of Ebola.
