C A team of Japanese scientists has discovered genes that enable rice to survive high water, providing hope for better rice production in lowland areas that are affected by flooding. The genes, called SNORKEL genes, help rice grow longer stems to deal with higher water levels. Deepwater rice generally produces lowyield rice plants. But the researchers report they have succeeded in introducing the genes to rice varieties that are higheryield. According to the report, as water levels rise, accumulation of the plant hormone makes the SNORKEL genes start working, making stem growth more rapid. When the researchers introduced the genes into rice that does not normally survive in deep water, they were able to rescue the plants from drowning. Motoyuki Ashikari, who headed the project, said his team is hoping to use the gene on long grain rice widely used in Southeast Asian to help stabilize production in flood areas where rice with the floodresistant gene is low in production about onethird to onequarter that of regular rice. Scientifically, the gene that we found is rare but clear proof of a biological ability to adapt to a difficult environment, he said. It39。 8. What did the man ask the woman to do? A. Take a break. B.

In some areas, rains can cause water levels to rise dangerously high during the growing season and flash flooding can fully submerge plants for days or even weeks. Rice is a main food for billions, and while productivity has increased dramatically since the 1960s, yields must be doubled to meet projected requirements by 2050. More than 30 percent of Asian and 40 percent of African rice land is either lowland field or deepwater field. Laurentius of Utrecht University said the study is significant because highyield rice varieties cannot survive extremes of floods. The introduction of these genes into highyield varieties, using advanced breeding strategies, promises to improve the quality and quantity of rice, he said. is the main character of SNORKEL genes? A. They prevent rice from being attacked by various diseases. B. They help rice grow taller in highland regions. C. They make rice grow tall enough to survive in deep water. D. They make rice be ripe within a shorter time. to Ashikari, the rice with the gene his team found ______. A. will be one third more expensive than regular rice B. has been widely used in Southeast Asia C. will be helpful for Southeast Asia D. is lower in production than regular rice underlined word“projected”in the seventh paragraph probably means _____.
