外研版英语九年级阅读理解试题及答案

Scientists have worked for twelve years to develop what they call Green Super Rice. The “green” in Green Super Rice means environmentally friendly. “Super” means the rice can grow well in bad soil conditions and keep away insects and diseases. Researchers say it will produce at least as much grain as other rice plants but with fewer inputs.

Modern rice plants produce two to three times more grain than that was possible before the 1960s. but they also require large amounts of water and chemical fertilizers. In the 1960s, scientists created crops that produced bigger harvests in what became known as the Green Revolution. It helped many people to get rid of hunger. But modern rice plants require too much water and too much use of chemical fertilizers and pesticides that can hurt the environment. And farmers may be too poor to buy these things to grow modern rice plants.

The developers of Green Super Rice do not use genetic engineering. In that way they avoid the high costs as well as the problems connecting with getting permission to plant genetic crops. Anna McClung leads a rice-breeding center for the United States Agriculture Department. She praises the researchers working on Green Super Rice. But she also says that combining many different genes into one plant without genetic engineering requires a lot of plant breeding.

The research is still going on. The researchers on the Green Super Rice project continue to help farmers produce more with less.
