Force other than damaging winds are also at work inside tornadoes. Sometimes, as the turning, jumping funnel(漏斗) passes over a house, the walls and ceiling burst apart as if a bomb had gone off inside. This explosion(爆炸) 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 funnel 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 57,600 pounds. The pressure on the four walls adds up to 172,800 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 great inside pressure may cause the building to burst.
Unfortunately, heavy rain happens in thunderstorms that later produce tornadoes. So, people often shut all windows to protect their property. This may cause far worse damage later.
63. Which of the following is the main topic of the passage?
A. Where tornadoes are formed. B. When tornadoes usually occur.
C. How tornadoes can be prevented. D. Why tornadoes cause so much damage.
64. According to the passage, tornadoes can destroy building 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 172,000 pounds
C. weight of a tornado can crush a building’s roof when it passes overhead
D. air pressure inside a tornado is less than the air pressure inside a building
65. According to the passage, the pressure on a building during a tornado can be reduced by _____.
A. closing the windows B. opening the windows
C. using an electric fan D. making the roof and walls stronger
Michel is a young girl who works for the police 36 a handwriting expert (专家). She has helped 37 many criminals (罪犯) by using her special talents (天才).

Every pet owner loves his pet. There is no argument here.
But when we asked our readers whether they would clone （克隆， 复制）their beloved animals, the responses（反应） were split almost down the middle. Of the 228 readers who answered it, 108 would clone, 111 would not and nine weighed each side without offering an opinion.
Clearly, from readers’ response, this is an issue that reaches deeply into both the joy and final sadness of owning a pet. It speaks, as well, to people’s widely differing expectations over the developing scientific procedure.
Most of the respondents who favored the idea strongly believed it would produce at least a close copy of the original; many felt the process would actually return an exact copy. Those on the other side, however, held little hope a clone could never truly recreate a pet, many simply didn’t wish to go against the natural law of life and death.
Both sides expressed equal love for their animals. More than a few respondents owned “the best dog/cat in the world”. They thought of their pets as their “best friend”, “a member of the family,”“the light of my life.” They told moving stories of pets’ heroism, intelligence and selfless devotion.
Then the loss is so disturbing---and the cloning so attractive. “People become very close to their animals, and the loss can be just as hard to bear as when a friend or family member dies,” says Gary Kowalski, author of Goodbye, Friend: Healing Wisdom for Anyone Who Has Ever Lost a Pet. “For me, cloning feels like an attempt to turn death away…It’s understandable. Death is always painful. It’s difficult to deal with. It’s hard to accept.”
But would cloning reduce the blow? This question seemed to be at the heart of this problem.
【小题1】So far as the cloning of pets is concerned, a recent survey shows that, of all pet owners, ____.
| A．a lot more of them are for it |
| B．a lot more of them are against it |
| C．very few of them are willing to tell their opinions |
| D．about half of them are for it and the other half against it |
| A．the death of one’s pet |
| B．the high cost of owning a pet |
| C．the troubles one has to deal with in keeping a pet |
| D．the dangers about the cloning of a pet |
| A．has never thought about the problem of cloning |
| B．is going to write another book on pets |
| C．is in favor of the idea of cloning pets |
| D．is all against the cloning of pets |
| A．Can cloning make the pain one suffers less when a pet dies? |
| B．Can pet owners afford the cost of cloning? |
| C．Does cloning go against the law of nature? |
| D．How reliably does cloning produce an exact copy of one’s pet? |
The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “limitless” and could “last forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.
Fifty years ago, nature study was not part of the school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.
For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table in ground is just as important to us as a knowledge of the basic math formulas. We need to know why all watersheds (上游集水区) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic (立方体的) volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can.
1.The author’s attitude towards the use of natural resources is _________.
A. positive B. uninterested C. optimistic D. critical
2.According to the author, the greatest mistake of our forefathers was that _________.
A. they had no idea about scientific forestry
B. they had little or no sense of environmental protection
C. they were not aware of the importance of nature study
D. they had no idea of how to make good use of raw materials
3.To avoid repeating the mistakes of our forefathers, the author suggests that _________.
A. we plant more trees
B. natural sciences be taught to everybody
C. environmental education be directed toward everyone
D. we return to nature
4.How can you understand the underlined sentence in the last paragraph?
A. Our living space on the earth is getting smaller and smaller.
B. Our living space should be measured in cubic volume.
C. We need to take some measures to protect space.
D. We must preserve good living conditions for both birds and animals.
