The health and welfare of every person in America will be affected by global warming, especially children, the elderly and the poor, according to a new White House science report.
The report said every region (地区) of the country will suffer worse health from heat waves and drought. All but a handful of states would have worse air quality and flooding. It predicts an increase in diseases spread by tainted (腐烂的) food, bad water and bugs (臭虫).
The report concludes that climate change causes real risk to human health and human system that supports the way of life in the United States.
Man-made global warming is caused by greenhouse gases from the burning of fossil fuels. At current emission (放射) levels, global temperatures are likely to rise by about 2 degrees by midcentury and about 7.5 degrees by the end of the century.
The most vulnerable (脆弱的) Americans — the poor, elderly, sick, very young and immigrants — will suffer more. That’s at least 10 percent of the country’s population, probably more. It will be tougher for these people to get enough health care for climate-related illnesses, to cool down in heat waves, to escape extreme events such as Hurricane Katrina, and even to get enough food.
While every region of America is vulnerable to global warming’s health and welfare effects, more people are moving to coastal regions, which are most vulnerable to climate change because of drought and hurricanes.
25. According to the report, we learn all of the following will risk human’s health EXCEPT ______.
A. heat waves and drought
B. increase in the number of bugs
C. reduction in carbon dioxide emissions
D. global warming and climate change
26. What does the underlined sentence in Paragraph 2 mean?
A. All of states would suffer flooding.
B. Air quality in few states is not high.
C. About half of all states would have clear air.
D. Flooding would occur in almost all the states.
27. Which of the following is NOT true according to the passage?
A. Global warming is caused by human beings.
B. It is wise for the Americans to move into coastal regions.
C. Global temperatures are increasing year by year because of carbon dioxide.
D. At least one tenth of Americans are more likely to suffer climate-related illnesses.
28. The writer wrote this passage to ______.
A. explain how the phenomenon of global warming forms
B. protect the vulnerable Americans from suffering from diseases
C. provide evidence that global warming and climate change risk human’s health
D. warn every American of the danger of global warming to their health

健康环保类文章阅读技巧:
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考,理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文,从结构上看大致可分为三个部分:
第一部分一般是文章的首段,主要用来提出文章的主题,即文章想要阐述、说明的主要内容;
第二部分是文章的主体,可由若干个段落组成,对文章的主题进行展开说明;
第三部分是结尾段,对文章的主题进行归纳总结。这类文章多用一般现在时,而且一般多使用客观性词语表述。有时为了强调客观性,也常使用被动语态。
从近几年的考试题来看,科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节,很多同学对此类文章感到费解。但一般的科普类文章都是就事论事,需要逻辑推理和想象的时候较少,因此此类阅读题也没有同学们想象中的那么难,只要多加训练,就能较好地答题。
【阅读策略】
1、概要(Summarizing):
阅完材料后,将所阅材料浓缩,摘要,做出所阅材料的书面或口头梗概。
2、组织(Organization):
阅读后根据阅读内容,识别观点、人物、事件之间的关系以及文章的结构关系。如:时间关系、比较或对比关系、相关关系及因果关系等。

Flu (which is short for influenza) is a highly infectious disease, the cause of which is a very tiny organism known as a virus. Several types of flu are recognized, depending on the type of virus that causes the disease.

Flu can often cause problems in breathing, and general infection of the lung. With elderly and weak people, these added complications often produce serious results. The virus, if not properly treated, can weaken the body so that patient may develop more serious illnesses, such as pneumonia and bronchitis. When people catch flu, they often complain of a headache or a sore throat. They usually have a fever and their temperature rises from the normal 37℃ (98.6) to about 39.5℃ (103). Sometimes a person has a dry hacking cough and aching joints.

Today many doctors use drugs that fight the disease. And scientists have also developed vaccines that help to prevent it. If the patient has proper treatment, and complete rest in bed, the virus is normally beaten within a week to ten days.

How does flu spread so quickly? When the infected person breathes out, sneezes or coughs, he gives out droplets of moisture in the breath from his mouth or nose. These remain in the air for some time. Flu viruses are present in these droplets. If a person sneezes in a crowd or poorly ventilated place, such as a lift, viruses can easily be carried from an infected person to a healthy person. This is known as droplet infection. The healthy person will breathe in the viruses given out by the infected person.

There are three main types of virus that cause flu, which are called type A, B and C. type A is the most powerful of the three, and undergoes minor changes in its genetic material every few years. The new form of the virus is called a strain. The new strain is not affected by the current vaccines. It is said to be “resistant” to them. So doctors must be continually producing new vaccines to combat the new strains of virus.
