After disappearing for over 19 years, measles (麻疹) is making a comeback in America. Since January 2019, the disease has infected more than 700 people, mostly small children, and the number seems to be increasing daily.
Measles is an infectious disease that typically begins with a high fever, cough, runny nose, and red, watery eyes. Many people also lose their appetites and feel sleepy. About three to four days after the symptoms start, the person breaks out into a rash (皮疹) that begins on the face at the hairline and then spreads to the neck and the rest of the body.
In healthy people, the recovery, which takes between two to three weeks, starts soon after the rash begins. However, for about 40 percent of patients—mainly kids under the age of five or older adults—the disease often leads to pneumonia (肺炎), which, if left untreated, could result in death.
The recent outbreak is thought to have been caused by travelers picking up the virus in a country where the disease is still existing and exposing it to an unvaccinated (未接种的) community in the US. In New York, it was carried back by someone who had recently visited Israel, which is currently undergoing a significant measles, while in Washington, “patient zero” was infected by a type that is currently circulating in Europe.
To limit the spread of the disease before it gets out of hand, US health officials are attempting to educate communities with high rates of unvaccinated children. They are also urging adults to consult with their physicians and get injected if considered necessary by the doctor.
Hopefully, health officials worldwide will be able to convince parents that vaccinating their children will protect, not harm, them.
文章大意：本文是一篇说明文。文章主要介绍麻疹在历史上带来的危害，以及为什么会发生这样的情况。
1．What is the third paragraph mainly about？__B__
A．The symptoms of measles.

解析：主旨大意题。根据第三段“In healthy people, the recovery, which takes between two to three weeks, starts soon after the rash begins. However, for about 40 percent of patients—mainly kids under the age of five or older adults—the disease often leads to pneumonia (肺炎), which, if left untreated, could result in death.”(对于健康的人来说，皮疹开始后不久就会开始康复，这需要两到三周的时间。然而，大约40%的患者——主要是5岁以下的儿童或老年人——患有肺炎，如果不及时治疗，可能会导致死亡。)可知，第三段讲述的是麻疹所产生的可能结果。故选B。
2．Why did some people develop measles in America？__D__
A．Because it is too hot this year.
B．Because people are too stressed.
C．Because pollution is too serious
D．Because the virus was taken to America.
解析：细节理解题。根据第四段中“The recent outbreak is thought to have been caused by travelers picking up the virus in a country where the disease is still existing and exposing it to an unvaccinated (未接种的) community in the US.”最近的疫情被认为是由于旅行者在一个病毒仍然存在的国家感染了该病毒，并将其暴露在美国一个未接种疫苗的社区。可知，美国有些人会患上麻疹是因为病毒被带到美国。故选D。
3．What do we know about measles？__D__
A．It never disappeared in America.
B．It starts with a rash.
C．It is mild to everyone.
D．It is possible to limit its spread.
解析：细节理解题。根据第五段中“To limit the spread of the disease before it gets out of hand, US health officials are attempting to educate communities with high rates of unvaccinated children.”(为了在疫情失控前控制疫情的蔓延，美国卫生官员正试图对未接种疫苗儿童比例较高的社区进行教育。)可知，限制麻疹的传播是可能的。故选D。
4．In which section of a newspaper may this text appear？__A__
A．Health.
B．Education.
C．Science.
D．Entertainment.
解析：推理判断题。根据最后一段“Hopefully, health officials worldwide will be able to convince parents that vaccinating their children will protect, not harm, them.”(希望世界各地的卫生官员能够说服父母，给孩子接种疫苗将保护他们，而不是伤害他们。)可知，这篇文章最有可能出现在报纸的健康栏目。故选A。
