Someday, the results could increase the amount of food produced around the world. s genes, the scientists were able to increase the amount of leaf growth on plants between 14 and 20 percent. s protective system. Normally, this system is activated when a plant gets too much sunlight, said scientist Krishna Niyogi, coauthor of the study. When the plant senses the light, it gets rid of extra energy and creates more leaves. When the plant is in shade, the protective system is turned off, but the process is slow. s protective system to lightadjusting glasses. When a person wears the glasses outside during the day, the lenses（鏡片）darken and lighten depending on how sunny it is. Plants do the same thing, he said. But in plants the adjustment can take anywhere from 10 minutes to an hour. This makes it hard for plants to get the right amount of sunlight needed to create food. s genes, the protective system turned on and off more quickly than normal. As a result, leaf growth on the plants scientists used in the study increased. Leaf growth in two plants increased by 20 percent, while leaf growth on a third plant increased by 14 percent. Scientists conducted the study on tobacco plants. But they think the genetic changes will produce the same results in corn and rice. （1）What will happen to the plants when scientists change plants39。To warn people of the hot and bright sun.B.To serve the science experiment smoothly.（3）In the future, the genetic changes will be used to.

A.They like to explore strange sea areas.The brainstorm of researchers.（3）Why do the scientists prefer to search for meteors in the ocean? A.B.A huge meteor shower.To observe movements of the universe.C. The crew of the Nautilus, a private research ship, recovered the rock particles(顆粒).The Nautilus is operated by the Ocean Exploration Trust. The group says its aim at present is to examine areas of the ocean that have never been explored before.根據(jù)最后一段中的“Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes”今后的工作將繼續(xù)側(cè)重于提高識(shí)別物體和成像形狀及體積的準(zhǔn)確性，故選B。s in airports.

But neither can it be reduced to the purely physical, as our inability to understand or even to recognise foreign languages makes clear. The food we eat shapes our jaws, and our jaws in turn shape the sounds of our language. The ease with which we eat probably shapes our thought too, as anyone who has suffered toothache could testify. What we eat may have shaped the sounds of our language, but how we eat changes how we feel and what we use language to expres
