Though the facts that too many people on earth and a too rapid increase in the number added each year are not in argument, we always begin the discussion of "population as global issue" with what most persons mean like this. It was quite right to compare demographic growth to "a long, thin powder fuse(導火線)that bums steadily and hesitatingly until it finally reaches the charge 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 populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility(生育)in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.
This pattern is important to notice. 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 mortality.
Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8000 B.C. till approximately 1650 A.D. In the first period of some 9,600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and 1975, the population has increased from 500 million to more than 4 billion. And the population reached 6.2 billion throughout the world by the year 2000, One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000 B.C. and 1650, an average of only 50,000 persons was being added annually to the world's population, At present, this number is added every six hours. The increase is about 800000,000 persons annually.

A. only one in ten persons could live past 40.
B. our ancestors had little enthusiasm for more children

根據短文內容，從短文后的選項中選出能填入空白處的最佳選項，選項中有兩項是多余的選項。
Have you ever found it difficult to understand a text or express your own idea? In fact, someone who always comes across these kinds of problems may have learning disabilities. Today we begin a series of programs about learning disabilities. These are disorders in the ways that people understand or use language. They can affect the ability to listen or think, or to speak or to read and write. They can also affect the ability to do mathematics. 1.Researchers believe that learning disabilities are caused by differences in the way that the brain works with information. They say children with learning disabilities are unintelligent or do not want to work. 2.
Researchers say that as many as one of every five people in the United States has some kind of learning disability. Almost three-million children in the United States receive some kind of help in school for a learning disability.
3.Experts look for a difference between how well a child does in school and the level of intelligence or ability of the child. But there is no one sign of a disorder. A few signs of learning disability include not connecting letters with their sounds or not understanding what is read. A person with a learning disability may not be able to understand a funny story. They may not follow directions. They may not read numbers correctly or know how to start a task.
_4._One person may have trouble understanding mathematics. Another may have difficulty understanding what people are saying. Still another may not be able to express ideas in writing. These different kinds of learning disabilities are known by different names. For example, a person who has difficulty reading may have dyslexia(誦讀困難癥)。
Experts say learning disabilities cannot be cured. 5._Teachers and parents can help young people with learning disabilities to learn successfully.
A. Different people have different kinds of learning disabilities.
B. Their brains just process information differently than other people.
C. People with learning disabilities have difficulty in communicating with others.
D. But people who have them can be helped.
