染雾高考英语阅读练习题《tornadoes》 篇一
Tornadoes are one of the most destructive natural disasters on Earth. They are violent rotating columns of air that are in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. Tornadoes can cause widespread damage and destruction, and they are often accompanied by strong winds, heavy rain, and lightning.
Tornadoes are most commonly found in the United States, particularly in an area known as Tornado Alley. Tornado Alley is a region that stretches from Texas to Iowa and is known for its frequent tornado activity. However, tornadoes can occur anywhere in the world, although they are most commonly found in areas with warm, moist air and strong winds.
The formation of a tornado begins with the development of a thunderstorm. As warm, moist air rises and meets cooler air, it can create an unstable atmosphere. This can cause the air to spin horizontally and create a rotating column of air. When this rotating column of air is tilted vertically, it can form a tornado.
Tornadoes vary in size, shape, and duration. They can range from being relatively small and short-lived to being large and long-lasting. The strength of a tornado is measured on the Enhanced Fujita (EF) scale, which rates tornadoes based on the damage they cause. The scale ranges from EF0, which causes minimal damage, to EF5, which causes catastrophic damage.
The destructive power of tornadoes is immense. They can destroy buildings, uproot trees, and toss vehicles into the air. They can also cause injuries and fatalities, and they can leave communities devastated in their wake. As a result, it is important for people to be prepared and to have a plan in place in case of a tornado.
In conclusion, tornadoes are powerful and destructive natural disasters. They can cause widespread damage and destruction, and they are often accompanied by strong winds, heavy rain, and lightning. While tornadoes are most commonly found in Tornado Alley in the United States, they can occur anywhere in the world. It is important for people to be prepared and to have a plan in place in case of a tornado.

Tornadoes are a fascinating natural phenomenon that have captivated scientists and researchers for centuries. These violent rotating columns of air are both beautiful and terrifying, with their swirling clouds and destructive power. In this article, we will explore the science behind tornadoes and the impact they have on the environment.
Tornadoes are formed from powerful thunderstorms that contain a rotating updraft. This updraft creates a mesocyclone, which is a region of rotating air within the storm. As the updraft continues to strengthen, the mesocyclone can extend downward to the ground, forming a tornado. The strength and duration of a tornado can vary greatly, with some tornadoes lasting only a few minutes while others can last for hours.
The destructive power of tornadoes is due to the strong winds they produce. Tornado winds can reach speeds of over 300 miles per hour, causing significant damage to anything in their path. Buildings can be destroyed, trees can be uprooted, and debris can be thrown for miles. The damage caused by tornadoes can be devastating to communities, and it often takes years to recover.
In addition to the physical damage they cause, tornadoes also have an impact on the environment. They can disrupt ecosystems by destroying habitats and displacing wildlife. Tornadoes also have the potential to cause significant pollution, as they can pick up and carry hazardous materials. This can contaminate water sources and pose a threat to both humans and wildlife.
Scientists and researchers are constantly studying tornadoes in order to better understand them and improve our ability to predict them. Doppler radar is one tool that has greatly advanced our understanding of tornado formation and development. This technology allows meteorologists to detect the rotation within thunderstorms and issue warnings for potential tornadoes.
In conclusion, tornadoes are a powerful and destructive force of nature. They are formed from powerful thunderstorms and can cause significant damage to communities and the environment. Scientists continue to study tornadoes in order to better understand them and improve our ability to predict them. By understanding the science behind tornadoes, we can better prepare and protect ourselves from their destructive power.

高考英语阅读练习题《tornadoes》
高中的英语学习是直接跟高考挂钩的，因此，考生要特别注意自己的平时的练习量。下面是小编整理的一篇高考英语阅读练习题，希望对大家有所帮助。
Forces other than damaging winds are also at work inside tornadoes(龙卷风). Sometimes, as the wind passes a house, the walls and ceiling burst apart as if a bomb had gone off inside. This explosion is caused by the low air pressure at the center of a tornado.
The pressure at the center of a tornado is usually 13 pounds per square inch. However, inside the house the air pressure is normal, about 15 pounds per square inch. The difference of 2 pounds per square inch between the inside and outside pressure may not seem like much. But suppose a tornado passes over a small building that measures 20 by 10 by 10 feet. On each square inch of
the building, there is 2 pounds of pressure from the inside that is not balanced by air pressure outside the building. On the ceiling, that adds up to an unbalanced pressure of 57600 pounds. The pressure of the four walls adds up to 172800 pounds.
If windows are open in the building, some of the inside air will rush out through them. This will balance the pressure inside and outside the building. But if the windows are shut tightly, the huge inside pressure may cause the building to burst.
Unfortunately, heavy rain often occurs in the storms that later produce tornadoes, so people often shut their windows. This may cause far worse damage later.
1.What did the paragraph before this passage most probably discuss?
A. Measuring rainfall from a storm B. The powerful winds of tornadoes.
C. The kinds of damage caused by explosions D. Repairing the damage from tornadoes.
2.Which of the following is the main topic of the passage?
A. How tornadoes can be prevented. B. When tornadoes usually occur. C. Where tornadoes are formed.
D. Why tornadoes cause so much damage.
3.Tornadoes can destroy buildings because the______.
A. force of a tornado increases the air pressure in a building. B. air pressure at the center of a tornado is over 172000 pounds.
C. weight of a tornado can destroy a building‘s roof when it passes over head. D. air pressure inside a tornado is less than the air pr
4.What is the difference per square inch between the air pressure inside a building and the air pressure inside a tornado?
A. 2 pounds. B. 10 pounds. C. 13 pounds. D. 15 pounds.

附：高中英语阅读障碍
1.语言的障碍。Readingis a comprehensive skill because it concerns the
recognition of configuration, pronunciation, grammatical inflexion and
the comprehension of words, sentences and paragraphs.(魏立明，孙长顺：2001
)由于有的单词往往有几种甚至几十种意思，而一个词的确切含义只有在具体的文章之中根据上下文才能确定。因此，词义的转换和搭配仍是阅读中的障碍。所以要
避免进入见词就查字典的误区。
2.文化背景知识的障碍。因为文化背景知识是阅读的无形障碍。由于不了解英语国家的文化背景，因此有时很难做出判断。People
believe that both visual and non-visual information is involved in
reading comprehension. As a matter of fact, it seems that the more
non-visual information the reader possess, the less visual information
is needed.(魏立明，孙长顺：2001 )。 所以多做泛读的`训练将有所帮助。
关于这两个障碍的排除在本文的以下部分中也有较详尽的论述。
3.阅读技巧的障碍。而这一障碍又是多方面的。如找中心思想，推断文章中有没有直接说明的意思，确定作者的语气等。本文将就这一方面进行重点论述。
