Why does the Leaning Tower of Pisa in Italy lean? It leans because of a mistake. It has leaned almost since the day the tower was built.
In 1173, the people of Pisa, Italy, wanted to build a bell tower. They wanted the tower to be the most beautiful bell tower in all of Italy. The city also needed a bell tower because the church did not have one.
However, there was a problem. As soon as the first floor of the building was finished, the tower started to lean. Builders tried to make the building straight again as they added more floors, but they couldn’t figure out how to make it stop leaning.
It took almost 180 years to finish the tower. Since then, the tower has leaned by another millimeter every year. Today, the Leaning Tower has eight floors and is 54.5 meters tall. By 1990, it was leaning by about 4 meters to one side. It was also slowly sinking into the ground. Many people became worried that it would soon fall apart.
In 1998, repair works began on the tower, and by the end of 2001, it had been moved back by 45 centimeters. The tower will still lean, however, so it will need to be repaired again---in another 200 years.

We can begin our discussion of population as a global issue with what most person mean when they discuss the population problem: too many people on earth and a too rapid increase in the number added each year. The facts are not in dispute. It was quite right to employ a similar matter that linked demographic(人口统计学)growth to a long, thin power fuse that burns steadily from time to time until it finally reaches the limit, and explodes.

To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history. We find that population have been really stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. For most of human history, it was seldom the case that one in ten persons would live past forty, where infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birth rates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.

This pattern is important to know. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high rate of death.

Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8000B.C. till approximately 1650 A.D. And a period of rapid growth since 1650. In the first period of some 9,600 years, the population increased form some 8 million to 500 million in 1650. Between 1650 and the present, the population has increased from 500 million to more than 4 billion. And it is estimated that by the year 2020 there will be 8 billion people throughout the world. One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000B.C. and 1650, an average of only 50,000 persons was being added annually to the worlds population each year. At present, this number is added very six hours. The increase is about 80,000,000 persons annually.

下面文章中有5(6165)需要添加小标题。请从以下选项(ABCDEF)中选出符合各段意思的小标题。选项中有一项是多余选项。

A. Control of Respiration

B. Basic tips for preserving cut flowers

C. Role of Respiration

D. Most Important Aspect of Flower Care

E. Need for Clean Water

F. Ways of Stopping Respiration

1. __________

????????????? While everybody enjoys fresh cut flowers around his house, few people know how to keep them for as long as possible. This may be done by keeping in mind a few simple facts. The key to keeping fresh cut flowers for a week or more without floral preservatives (which contain biocides that kill bacteria and fungus) is to keep the water fresh and the stems free of air pockets so they can continue to draw up water.

2.__________

????????????? An important thing to remember about cut flowers is that they are sensitive to temperature. For example, studies have shown that cut carnations(康乃馨) retain their freshness eight times longer when kept at 12 than when kept at 26. Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care.

3.__________

????????????? Flowers are not intended by nature to live very long. Their biological purpose is simply to attract birds or insects, such as bees, for pollination (授粉). After that, they quickly dry up and die. The process by which flowers consume oxygen and produce carbon dioxide, called respiration (呼吸), generates the energy the flower needs to give the flower its shape and color. The making of seeds also depends on this energy. While all living things respire, flowers have a high level of respiration. A result of all this respiration is heat, and for flowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies.

4. __________

????????????? How, then, to control the rate at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature. We know that respiration produces heat, but the reverse is also true. Thus by maintaining low temperatures, respiration is reduced and the cut flower will age more slowly.

5. __________

????????????? Another vital factor in keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to “drink” water that is dirty or otherwise polluted. Even when water looks and smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, household chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach (at 4% solution) be added to each liter of water. The water and solution should also be replaced each day.

 

Nowadays, the food we eat seems to have great effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures.

That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.

1.What is the best possible title of the passage?

A. Drug and Food                                 B. Food and Health

C. Cancer and Health               D. Health and Drug

2.Which of the following statements is NOT true?

A. Some of the additives in our food are added to the food itself and some are given to the living animals

B. Researchers have known about the potential dangers of food additives for about sixty-eight years.

C. Drugs are always given to animals for medical reasons

D. Food may cause forty percent of cancer in world.

3.How has science done something harmful to mankind?

A. Because of science, diseases caused by polluted food have been virtually eliminated.

B. It has caused a lack of information concerning the value of food.

C. The scientists have preserved the color of meats, but not of vegetables.

D. Because of the application of science, some potentially harmful substances have been added to food.

4.What are nitrates used for?

A. They preserve the color of meats.

B. They preserve flavor in packaged foods.

C. They are the objects of research

D. They cause the animals to become fatter.

5.The word “carcinogenic” most nearly means “_____”.

A. trouble-making                             B. color-retaining

C. cancer-causing                             D. money-making
