[山西太原2021月考]
The Chinese Doctor Who Beat the Plague (瘟疫)
In the winter of 1910, Dr Wu Lien teh stepped off a train in the northern Chinese city of Harbin.He was there to solve a medical mystery, at great personal risk.Over the past few months, an unknown disease had swept along the railways of Northeast China, killing 99.9% of its victims.The Qing Imperial court had sent the Cambridge educated Dr Wu north to stop the epidemic.
When Dr Wu arrived in Harbin on Christmas Eve, 1910, he carried little in the way of medical instruments and had only one assistant.One of Wu's first acts upon arrival was to set up special quarantine (隔离) units and to order lockdowns to stop infected people from travelling and spreading the disease.He had teams check households for possible cases, and even managed to convince authorities to completely close the railways in the early weeks of 1911.Of particular concern was the upcoming Chinese New Year holiday, which had become a great annual migration of people travelling across the country to see their families.

Thanks to Dr Wu’s efforts, the number of plague victims began to die down, and by March 1st, 1911, the epidemic was fully contained.The pneumonic (肺炎的) plague outbreak of 1910—1911 lasted nearly four months, affected five provinces and six major cities, and accounted for over 60 ,000 deaths.It is clear that without the brave and decisive action taken by Dr Wu it could have been much worse.Had the epidemic gone unchecked, allowing holiday rail passengers to spread the disease to the rest of China could have meant a catastrophic loss of life and possibly a global health crisis.
In April 1911, Dr Wu chaired the International Plague Conference in Shenyang, attended by scientists from 11 countries including the United States, Great Britain, Russia, Japan and France.They praised Dr Wu for his handling of the 1910—1911 outbreak.For a time, Dr Wu was the world’s most famous plague fighter, a title he defended in a malaria epidemic in China in 1919, and a return of plague in 1921.

【语篇导读】本文是一篇记叙文,讲述了中国医生伍连德带领全国人民战胜瘟疫的故事。
答案及解析
1.B 细节理解题。根据第一段中的The Qing Imperial court had sent the Cambridge educated Dr Wu north to stop the epidemic.可知,伍医生被派去北方的目的是阻止一场流行病。故选B。
2.Which of Dr Wu’s acts stopped the disease from spreading nationwide
A.Setting up special quarantine units.
B.Carrying medical instruments with him.
C.Checking households for possible cases.
D.Convincing authorities to close the railways.
答案及解析
2.D 细节理解题。根据第二段中的… even managed to convince authorities to completely close the railways in the early weeks of 1911… travelling across the country to see their families.可知,他说服当局彻底关闭了铁路,因为即将到来的新年假期是每年一次的人口大迁移,人们会去往全国各处走亲访友。由此可知,关闭铁路这一举措阻止了疾病在全国范围内传播。故选D。
3.What can we infer from the third paragraph
A.The disease worsened after March 1st, 1911.
B.60 ,000 people would have died without Dr Wu’s efforts.

答案及解析
3.C 推理判断题。根据第三段中的最后两句可知,很明显如果没有伍医生采取的果断行动,情况会更糟。如果对流行病置之不理且不封铁路,允许旅客把疾病传播到中国其他地方就意味着灾难性的生命损失,并可能造成全球健康危机。故从第三段能推断出,1911年世界免于一场大规模疫情。故选C。
4.What can we know about Dr Wu from the last paragraph
A.He continued to fight plagues after 1911.
B.He was infected with malaria in 1919.
C.He travelled worldwide hosting conferences.
D.He claimed plagues would never happen again.
答案及解析
4.A 推理判断题。根据最后一段中的For a time, Dr Wu was the world’s most famous plague fighter, a title he defended in a malaria epidemic in China in 1919, and a return of plague in 1921.可知,伍医生一度成为世界上最著名的抗疫斗士,在1919年中国疟疾流行和1921年鼠疫卷土重来的时候,他保留了这个头衔。由此判断出1911年后,他仍继续与瘟疫作斗争。故选A。
[山东2022高二“山东学情”期中联考]Scientists were working to stop a deadly virus that infected pigs.This African swine flu (猪流感) virus was causing huge losses for farmers in China and other Asian countries.Many farmers had tried to contain it by destroying infected animals.But the spread of the disease into East Asia had stepped up the search for other ways to deal with the problem.
The virus had not been considered a major concern for researchers until it appeared in China.Chinese farmers raise about half of the world’s pigs.Some researchers think the virus might have come from infected animals in Eastern Europe.Since then, it had spread to China, Vietnam and other Asian countries.Millions of pigs had been destroyed.
Although swine flu does not make people sick, it is very infectious and deadly to pigs.As the deadly virus killed pigs across Asia, scientists were speeding up their efforts to develop a vaccine.“Today’s situation, where you have this global threat, puts a lot more emphasis on it, ” said Doctor Luis Rodriguez, who leads the United States government laboratory for foreign animal diseases.

Vaccines are often developed by killing a virus before it is injected (注射) into an animal.The disabled virus does not make the animal sick, but it activates the body's natural defences against disease.The immune system is then able to identify the virus and produce antibodies against it.However, this method is not effective with all viruses including the one that causes African swine flu.For swine flu, scientists have been working on a different kind of vaccine.It is made from a weakened virus, not a dead one.The problem for researchers has been how to change the virus so it can be safely used.
Vietnam’s government reported a few weeks ago that it was testing vaccines, but provided few details.In China, the government said scientists were working on a vaccine that genetically changes the virus, which is similar to a method being used by scientists in the US.
