Population tends to grow at an exponential(指数的)rate. This means that they progressively double. As an example of this type of growth rate, take one penny and double every day for one month. After the first week, you would have only 64 cents, but after the fourth week you would have over a million dollars.

This helps explain why the population has come on "all of a sudden". It took from the beginning of human life to the year 1830 for the population of the earth to reach one billion. That repents(缓慢进行)a time span of at least two million years. Then it took from 1830 to 1930 for world population to reach 2 billion. The next billion was added by 1960, only thirty years, and in 1975 world population reached 4 billion, which is another billion people in only fifteen years.

World population is increasing at a rate of 9000 per hour, 220000 per day, and 80 million per year. This is not only due to higher birth rate, but to lower death rate as well. The number of births has not declined at the same rate as the number of deaths.

Some countries, such as Columbia, Thailand, Morocco, Costa Rica, and the Philippines, are doubling their population about every twenty-one years, with a growth rate of 3.3% a year or more. The United States is doubling its population about very eighty-seven years, with a rate of 0.8% per year. Every time a population doubles, the country involved needs twice as much of everything, including hospitals, schools, resources, food and medicines to care for its people. It is easy to see that this is very difficult to achieve for the more rapidly growing countries.

This passage chiefly discusses______.

A．the growth of world population

B．one type of the exponential rate

C．the population problem of more rapidly growing countries

D．the possible ways of dealing with the rapid population growth

B.The movement type used controls field selection for the goods movement transaction

C.If you use special stock indicators, you can create different stock and value updates of a material for one and the same movement type

D.Goods movements, that are created from other application areas (for example a delivery in SD), are not described with movement types

E.The movement type influences the update of material stock account and consumption account.
