Question

The current Ebola (埃博拉病毒) outbreak in western and central Africa has infected at least 3 069 people including 1 552 dead making it the largest outbreak in history. Ebola is a deadly virus —about 60 percent of people infected with it have died.

How is Ebola doing its harm?

When a person becomes infected with Ebola the virus damages the body’s immune (免疫的) cells which defend against infection said a researcher at Lancaster University. But if a person’s immune system can stand up to this attack then he is more likely to survive the disease.

The patients that survive it best are those who don’t get such a bad disadvantage in immune system. But if the body isn’t able to get rid of this attack then the immune system becomes less able to regulate (调节) itself. This means the immune system is more likely to run out of control leading to a drop in blood pressure multi-organ failure and eventually death.

What are the common symptoms of the disease?

Fever. Headache. Joint and muscle aches. Weakness. Diarrhea. Vomiting. Stomach pain. Lack of appetite. Chills. Rash. Redness in the eyes. Hiccups. Cough. Sore throat. Chest pain. Difficult breathing or swallowing. Bleeding inside and outside of the body.

How to prevent the spread of Ebola?

Ebola can be spread primarily via direct contact with patients specifically the blood and fluids of an infected patient.

We should avoid contact with infected patients and objects such as clothing bedding and needles used by them. Avoid areas where infections have been reported. For now the disease has only been confirmed in central and West Africa four cases in America and Europe. Avoid eating wild-caught bush meat. Researchers have suspected that the disease came to humans via animals probably through the meat of primates(灵长类). If you’re in an area where the disease has been reported avoid purchasing eating or handling wild game to stay on the safe side.

Wear protective medical clothing if you’re around infected patients. Extreme caution is necessary. Hospital workers must use masks gloves goggles and gowns which needed to be worn at all times if you’re around infected patients.

How Do People Survive Ebola?

Doctors don’t know for certain who will survive Ebola and there is no specific treatment or cure for the disease. Although in the minority some people do recover from infection.

Our suggestions include:

Maintain your electrolytes (电解质) and body liquid. Sports drinks can be used. Monitor your blood pressure and control it if necessary. Dropping blood pressure may be a serious sign of infection. Breathe in an oxygen-rich environment. Quickly address any symptoms of infection. Be honest about when and where you’re feeling pain.

分 析：
当一个人被Ebola 感染时，病毒就伤害了身体的免疫细胞。研究者怀疑疾病是通过动物传给人的，很可能是通过灵长类的肉。提醒人们避免吃野生野味。

1.1】C细节理解题。根据第一小标题第一段第一句When a person becomes infected with Ebola the virus damages the body’s immune (免疫的) cells 当一个人被Ebola 感染时，病毒就伤害了身体的免疫细胞。故选C。

2.2】D细节理解题。根据第二小标题中Fever. Headache. Joint and muscle aches. Weakness. Diarrhea. Vomiting. Stomach pain. Lack of appetite. Chills. Rash. Redness in the eyes. Hiccups. Cough. Sore throat. Chest pain. Difficult breathing or swallowing. Bleeding inside and outside of the body.从这里可知文中提到了Fever 发烧，Chills冷，Difficult breathing or swallowing呼吸或吞咽困难，Bleeding inside and outside of the body.血流到身体外面。文中未提到High blood pressure.高血压。故选D。

3.3】B推理判断题。根据第三小标题第二段第三句Avoid eating wild-caught bush meat. Researchers have suspected that the disease came to humans via animals probably through the meat of primates(灵长类). 避免吃野生野味。研究者怀疑疾病是通过动物传给人的，很可能是通过灵长类的肉。故选B。

4.4】A推理判断题。根据第四小标题第一段第二句Although in the minority some people do recover from infection.尽管是少数，一些人确实从感染中恢复了。故选A。
