高考英語(yǔ)閱讀練習(xí)題《tornadoes》
高中的英語(yǔ)學(xué)習(xí)是直接跟高考掛鉤的，因此，考生要特別注意自己的平時(shí)的練習(xí)量。下面是小編整理的一篇高考英語(yǔ)閱讀練習(xí)題，希望對(duì)大家有所幫助。
Forces other than damaging winds are also at work inside tornadoes(龍卷風(fēng)). 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 pressure inside a building.
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.
答案：CDDA
附：高中英語(yǔ)閱讀障礙
1.語(yǔ)言的障礙。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，孫長(zhǎng)順：2001
)由于有的單詞往往有幾種甚至幾十種意思，而一個(gè)詞的確切含義只有在具體的文章之中根據(jù)上下文才能確定。因此，詞義的轉(zhuǎn)換和搭配仍是閱讀中的障礙。所以要
避免進(jìn)入見(jiàn)詞就查字典的誤區(qū)。
2.文化背景知識(shí)的障礙。因?yàn)槲幕尘爸R(shí)是閱讀的無(wú)形障礙。由于不了解英語(yǔ)國(guó)家的文化背景，因此有時(shí)很難做出判斷。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，孫長(zhǎng)順：2001 )。 所以多做泛讀的訓(xùn)練將有所幫助。
關(guān)于這兩個(gè)障礙的排除在本文的以下部分中也有較詳盡的論述。
3.閱讀技巧的障礙。而這一障礙又是多方面的。如找中心思想，推斷文章中有沒(méi)有直接說(shuō)明的意思，確定作者的語(yǔ)氣等。本文將就這一方面進(jìn)行重點(diǎn)論述。
