Crop Problem
? ?Advances
in technology have helped more of the world’s population live better and longer,
and that is part of our problem[
? ?Better health standards have
kept larger number of people alive. The world’s population is now almost four
billion and expected to double in 25 years. Growing population and slowly rising
living standards have increased our need for food at the rate of 30 million tons
per year. As a result, the world’s stockpile of food(食物储备) is declining by about
10 million tons per year.
? ?From the early 1950s until 1972 ,world
food production increased greatly. The Green Revolution (绿色革命) extended
scientific techniques to agriculture in the form of hybrid seed (杂交种)and poultry
(禽类), chemical fertilizers (化学肥料) and pesticides (杀虫剂), and complex irrigation
systems. Strains (品种) of corn (玉米), sorghum (高粱), soybeans (大豆), wheat and rice
were developed to flourish under particular climate and soil
conditions.
? ?In the United States, corn production rose to 110
bushels(蒲式耳：谷物、水果、蔬菜等容量单位，在英国相当于36,368升，在美国相当于35,238升) per acre from only 26
bushels per acre in the early 1900s. Milk production rose to 10,000 pounds per
cow per year, compared with 600 in India. Chickens were bred to eat less, grow
to maturity in shorter time, and produce more eggs. As a result of such
scientific advances, our twelve midwestern states alone now feed one fourth of
the world’s people.
? ?Crop disaster in 1972 brought an apparent
end to the growth in production. Much of the extra yields had come from the use
of chemical fertilizers, primarily petroleum based and now in short supply. The
drop in world supplies of petroleum-based fertilizers is expected to cause a
drop in crop yields of ten tons for each one ton decline in fertilizers
applied.
? ?This presents a particular problem for underdeveloped
nations that often lack the foreign exchange necessary for buying fertilizer.
The problem is so severe that Philip Handier, president of the National Academy
of Sciences, has predicted one million child deaths per month in these nations
by the year 2025. |
Judging from the passage ,the term "Green Revolution" refers to______.
A:the political situation in Greenland B:the increased use of scientific methods in agriculture C:the upheavals in the underdeveloped nations D:the crop shortages experienced in 1972
In the late 1960s and early 1970s, New York legislators faced a drug problem they feared was growing out of control. Federal statistics showed as many as 559,000 users nationwide and state police saw a 31 percent increase in drug arrests by 1972. In response Gov. Nelson Rockefeller created the Narcotic Addiction and Control Commission in 1967, aimed at helping addicts get clean. After the program proved too costly and ineffective. New York launched the Methadone(美沙酮) Maintenance Program, which similarly caused little reduction in drug use. But by 1973, calls for stricter penalties had grown too loud to ignore, prompting Albany to pass legislation that created required minimum sentences of 15 years to life for possession of four ounces of narcotics—about the same as a sentence for second -degree murder.
What was troubling New York in late 1960s and early 1970s according to the passage
A:There were 559,000 drug users in the state. B:There was a 31% increase in drug use by 1972. C:It was short of money solving drug problem. D:The drug problem seemed going out of control.
黄河自1972年首次在山东省利津县断流，到1996年累计断流已达57次，共682天。今年以来已断流10次之多！往常断流多在5、6月份，而今年则于2月7日开始，首次断流为15天；1995年全年为122天，1996年全年为136天。1994年断流河段到达河南开封附近的陈桥，长达683公里，占下流河段总长的87%。断流使下流泥沙淤积日趋严重，郑州以下780公里河床，每年增高近10厘米。入海口鱼类减少，沙化、盐碱化日益严重，生态环境遭破坏，造成工农业经济损失约268亿元。 这段话最主要的意思是说( )。
A:自1972年以来，黄河山东段开始断流，以后日趋严重，经济损失大 B:自1994年以来，黄河断流河段占下游河段总长的87%，经济损失严重 C:自1972年以来，黄河断流现象日趋严重，已造成数百亿元的损失 D:自1972年以来，黄河断流严重影响工农业生产发展
