It was in a brightly-lit room in Mexico City, Mexico, that on June 18, 2014 it was announced that India-born Dr Sanjaya Rajaram had been named the winner of the World Food Prize. 

Dr Rajaram won this award for successfully crossbreeding (杂交) the winter and spring wheat (小麦) varieties, which have been two distinct and isolated gene pools (分离的基因库) since the beginning of farming. And because of this breakthrough, the scientist has been able to breed over 480 wheat varieties. 

Born in Varanasi in 1943, Dr Rajaram lived with his family off a plot of land growing wheat, rice and maize. "After my education here in India, I went off to Australia for my PhD and soon I joined CIMMYT (the International Maize and Wheat Improvement Centre) in Mexico, where my career as a plant breeder started, " said Dr Rajaram. 

"Every country is unique — there are climate systems, culture, the financial situation and each of the nations I visited needed a different set of solutions, " said Dr Rajaram. His solutions became part of what is widely described as the world's first "wheat network", a global exchange of "genetic information and innovations among researchers". His varieties of wheat were strong in nutrition, delayed (延迟) the attack of some plant diseases and were able to survive the severest of conditions. 

After nearly half a century in the field, Dr Rajaram said his work was still not finished. "In science, you never stop learning. I have been doing this all my life and I've never really had time for anything else. As far as hobbies go, well, there's a bit of music I like to listen to and that's pretty much it. I have been on a long journey of pushing the boundaries (边界) of what's possible and today, there's still work left. Learning must never stop and the world must not go hungry. "

(1) Why was Dr Rajaram awarded the World Food Prize? A. He improved several wheat varieties genetically. B. He crossbred the winter and spring wheat varieties. C. He successfully bred two wheat varieties. D. He found the difference between the winter and spring wheat varieties.
(2) When did Dr Rajaram start to work on plant breeding? A. During his college years in India. B. While doing his PhD in Australia. C. After becoming a member of CIMMYT in Mexico. D. While living with his family near wheat-growing land.
(3) What is one advantage of the wheat varieties developed by Dr Rajaram? A. They can be planted in any season. B. They are free from the attack of some pant diseases. C. They can grow well in terrible environments. D. They can grow taller than traditional ones.
(4) What can we learn about Dr Rajaram from the last paragraph? A. He was too busy with work to develop any hobby. B. He wasn't satisfied with the results of his research. C. He planned to do research in a new field of science. D. He made his mind to work on world food problems.
