Question

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(時疫) 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

3.C

【解析】

試題解析：文章講了埃博拉病毒的傳播以及Khan博士對病毒傳播的預測情況。

1. Khan, who examines global airline travel patterns to predict the spread of diseases,” Khan博士通過測試全球航線旅游模式來預測疾病的傳播。故選B。

2. risk of international spread would be further _____ if this epidemic were to take hold in other countries, especially those with weak public health systems.”如果這個時疫在其它國家固定下來，特別是公共健康系統(tǒng)薄弱的國家，傳播的風險會怎么樣，公共健康系統(tǒng)薄弱的國家醫(yī)療水平應該是比較低的，因此可推測出傳播的風險是提高。故選B。

3.
