阅读表达 (满分10分) [1]A researcher who helped make crops grow in dry land areas received the World Food Prize last week. Daniel Hillel was recognized for his work in developing what is called “micro-irrigation' or “drip irrigation.' It has made farming possible in places where there is little rainfall or water. [2]Daniel Hillel's farm near his home in Israel shows his ideas at work. “Each tree row is fed by these plastic tubes that drip water at the base of the tree.' Watering plants drop by drop has changed agriculture by reducing the amount of water needed to grow crops. [3]Farmers now depend on drip irrigation in many areas, including vineyards in Spain, onion fields in Africa, and even farms in the United States. Farmers in California grow about fifty percent of the fruits and vegetables of the continental United States. And the reason that is possible is because of these drip and micro-irrigation techniques. [4]Daniel Hillel was born in California. After his father died, his mother moved the family to Palestine, where her parents lived. The area eventually became part of the state of Israel. Daniel Hillel got his start in dry land farming as a settler in Israel's Negev Desert in the 1950s. “The issue was efficient use of water because land is available and extensive while Water is limited.' [5]Desert farmers were not able to push water through irrigation canals to their crops the way farmers have since ancient times. So Mr. Hillel and others gave plants just what they needed, just where they needed it. The idea was to apply the water little by little. The method worked so well that soon Mr. Hillel was traveling the world, showing others _____. 小题1:Why did Daniel Hillel win the World Food Prize?   ( no more than15 words) _____________________________________________________________________ 小题2:How did drip irrigation change agriculture?
