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.

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。
