第二篇：More Rural Research is Needed
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.
"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.
Research is needed to solve food production,land degradation(贫瘠化)and environmental problems.Secure local food supplies led to economic growth which is turn,slowed population growth.Dr.Fischer painted a picture of the world's ability to feed itself in the first 25 years,when the world's population is expected to rise from 5 X to X billion people.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 sub-Saharan Africa and southern Asia in 2020,similar to the currenti pattern.If there is any change,a slighe improvement will be seen in southern Asia,but not in sub-Saharan Africa.The major improvement will be in East Asia,South America and South-East Asia.
The debeloping world was investing about 0.5%,or $8 billion a year,of its agricultural gross domestic product(GDP)on research and developed world was spending 2.5% of its GDP.Dr.Fischer said more was needed from all countries.
He said crop research could produce technologies that spread across many countries,such as wheat production research having spin-offs(有用的副产品)for Mexico,China or India.
"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.
Yields of rice,wheat ad 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 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.

第三篇：Dangers await babies with altitude
Women who live in the world's highest communities tend to give birth to under-weight babies,a new study suggests.These babies may grow into adults with a high risk of heart disease and strokes.
Research has hinted that newborns in mountain communities are lighter than average.But it wasn't clear whether this is due to reduced oxygen levels at high altitude or because their mothers are under-nourished—many people who live at high altitudes are relatively poor compared with those living lower down.
To find out more,Dino Giussani and his team at Cambridge University studied the records of 400 births in Bolivia during 1976 and 1998.The babies were born in both rich and poor areas of two cities： La Paz and Santa Cruz.L Paz is the highest city in the world,at 3.65 kilometers above sea level,while Santa Cruz is much lower,at 0.44 kilometers.
