More Rural Research is Needed

1．Agricultural research funding is vital if the world is to feed itself better than it does now．Dr．Tony Fischer, crop scientist, said demand was growing at 2．5% per year, but with modern technologies and the development of new ones, the world should be able to stay ahead.

2．"The global decline in investment in international agricultural research must be reversed if significant.progress is to be made towards reducing malnutrition(营养不良)and poverty," he said.

3．Research is needed to solve food production, land degradation(贫瘠化)and environmental problem．Secure local food supplies led to economic growth which, in turn, slowed population growth．Dr．Fischer painted a picture of the world's ability to feed itself in the first 25 years of the new century, when the world's population is expected to rise from 5.8 to 8 billion．He said that things will probably hold or improve but there'll still be a lot of hungry people．The biggest concentration of poor and hungry people would be :in subSaharan Africa and southern Asia in 2020, similar to the current pattern．If there is any change, a slight improvement will be seen in southern Asia, but not in subSaharan Africa．The major improvement will be in East Asia, South America and Southeastern Asia.

4．The developing world was investing about 0．5%, or $8 billion a year, of its agricultural gross domestic product (GDP) on research, and the developed world was spending 2.5 % of its GDP．Dr．Fisher said more was needed from all countries.

5．He said crop research could produce technologies, that spread across many countries, such as wheat, production research having spin-offs for Mexico, China or India.

6．"Technologies still need to be refined for the local conditions but a lot of the strategic research can have global application, so that money can be used very efficiently," Dr.Fischer said.

7．Yields of rice, wheat and maize(玉米)have grown impressively in the past 30 years,especially in developing .countries．For example, maize production rose from 2 to 8 tonnes per hectare(公顷)between 1950 and 1995．But technologies driving this growth, such as high-yield varieties, fertilizers and irrigation, were becoming exhausted．"If you want to save the land for non-agricultural activities, for forests and wildlife, you're going to have to increase yield," Dr．Fischer said.

A．The Same or Improved Food Supply Situation in 2020

B．Research Focus on Increased Yield

C More Research Funding Needed

D．Local Situations Analyzed

E．Increase in Investment on Agricultural Research

F．Sustained Development of Modern Technologies

A New Finding British cancer researchers have found that childhood leukaemia is caused by

A New Finding

British cancer researchers have found that childhood leukaemia is caused by an infection and clusters of cases around industrial sites are the result of population mixing that increases exposure. The research published in the British Journal of Cancer backs up a 1988 theory that some as yet unidentified infection caused leukaemia—not the environmental factors widely blamed for the disease.

“Childhood leukaemia appears to be an unusual result of a common infection,” said Sir Richard Doll, an internationally—known cancer expert who first linked tobacco with lung cancer in 1950. “A virus is the most likely explanation. You would get an increased risk of it if you suddenly put a lot of people from large towns in a rural area, where you might have people who had not been exposed to the infection.” Doll was commenting on the new findings by researchers at Newcastle University, which focused on a cluster of leukaemia cases around the Sellafield nuclear reprocessing plant in Cumbria in northern England. Scientists have been trying to establish why there was more leukaemia in children around the Sellafield area, but have failed to establish a link with radiation or pollution. The Newcastle University research by Heather Dickinson and Louise Parker showed the cluster of cases could have been predicted because of the amount of population mixing going on in the area, as large numbers of construction workers and nuclear staff moved into a rural setting. “Our study shows that population mixing can account for the (Sellafield) leukaemia cluster and that all children, whether their parents are incomers or locals, are at a higher risk if they are born in an area of high population mixing,” Dickinson said in a statement issued by the Cancer Research Campaign, which publishes the British Journal of Cancer.

Their paper adds crucial weight to the 1988 theory put forward by Leo Kinlen, a cancer epidemiologist at Oxford University, who said that exposure to a common unidentified infection through population mixing resulted in the disease.

Who first hinted at the possible cause of childhood leukaemia by infection？______

A．Leo Kinlen.

B．Richard Doll.

C．Louise Parker.

D．Heather Dickinson.

听力原文：Not everybody reads the daily newspaper. People who do not read newspapers are so

听力原文： Not everybody reads the daily newspaper. People who do not read newspapers are sometimes referred to as nonreaders. Early research has shown that nonreaders are generally low in education, low in income, either very young or very old. In addition, nonreaders are more likely to live in rural areas and have less contact with neighbors and friends. Other studies show that nonreaders tend to isolated themselves from the community, are less likely to own a home and seldom belong to local voluntary organizations. Why don't these people read the daily paper？ They say they don't have the time; they prefer radio or TV; they have no interest in reading at all. And besides, they think newspapers are too expensive. Recent surveys, however, have indicated that the portrait of the nonreader is more complicated than first thought. There appears to be a group of nonreaders that does not fit the type mentioned above. They are high in income, and fall into the age group of 2665. They axe far more likely to report that they don't have the time to read the papers and they have no interest in the content. Editors and publishers axe attempting to win them back. First, they are adding news briefs and comprehensive indexes. This will help overcome the time problem. And they are also giving variety to newspaper content to help build the readers' interest.

A．They are interested in other kinds of reading.

B．They are active in voluntary services.

C．They tend to be low in education and in income.

D．They live in isolated areas.

A study that will cost $ 3.2 billion and last more than two decades to track the health of
100,000 U. S. children from before birth to age 21 will be launched in January, U. S. health officials said on Friday.

Officials from the U. S. government's National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness.

The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health.

Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said.

Officials said more than $ 200 million has been spent already and the study is projected to cost $ 3.2 billion.

"We anticipate that in the long term, what we learn from the study will result in a significant savings in the nation's health care costs," Dr. Duane Alexander, who heads the NIH 's Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters.

The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21.

Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheidt of the NIH, who heads the study.

The people taking part will be from rural, urban and suburban areas, from all in- come and educational levels and from all racial groups, the NIH said.

The aim of the study is to find new ways to______.

A．conduct research

B．track public health

C．prevent or treat illness

D．speed up development
