Dr. Tony Fischer,crop scientist,said demand was growing at 2.5% per year but with modern technologies and the development of new ones,

37、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.

Dr. Fischer said more was needed fr

41、om all countries. He said crop research could produce technologies that spread across many countries,such as wheat production research having spin-offs(有用副产品)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

42、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 t

43、his 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,youre going to have to increase yield.Dr. Fischer said. 36.What is the passage mainly about?A. Shortage of food supplies. B

44、. Development of agricultural technologies. C. Impact of agricultural research. D. Expectation of population growth. 37. Which of the following statements is true about the worlds agricultural research funding?A. It is increasing among developed countries. B. It is decreasing worldwide. C. Less is d

45、emanded from developing countries. D. Most of it is spent very efficiently. 38. What is the picture of Asias food supplies in the first 25 years?A. Food shortage will not be a problem. B. There will be more hungry people in southern Asia. C. Population growth will result in more hungry people. D. Th

46、ere will be fewer hungry people in East Asia. 39. What does Dr. Fischer say about technologies?A. They are costly. B. They have to be improved to meet local needs. C. Their application is limited. D. They have to be applied locally. 40. It can be infered from the last paragraph that_. A. there is a demand for saving land for non-agricultural activitie
