单选题Researchers from the Shaare Zedek Medical Center and Bar-Ilan University just released a report explaining how a new type of eye drop 27 with 'nanoparticles' could replace the need for glasses or contacts. It's a bit 28 and requires a brief doctor visit, but it apparently works like a charm. The three-step process starts with a 29 of the individual's eye refraction (屈光度), which can be performed with a smartphone. Then, doctors create a very specific laser pattern which is applied to the eye for less than one second. The laser creates tiny 30 in the surface of the cornea. Lastly, special eye drops are applied. 'These nanoparticles go into the shallow ablated patterns generated on the surface of the cornea,' Zeev Zalevsky explained to Digital Trends. 'They change the refraction index inside of those patterns. This corrects the 31 problem the user has. The process of correction can be done at home without the need of a medical doctor.' The procedure is less 32 than traditional laser eye surgery in that it only affects the exterior of the eye and does not require an extensive procedure. However, because the 33 to the eye are so minor, the tiny etchings in the cornea eventually heal themselves and vision 34 degrades. The researchers believe the positive effects of the treatment will last one to two months. Heading to the eye doctor for a reapplication of the laser every two months sounds pretty 35 , but the technology is still in its infancy. Going forward, the researchers are planning additional testing and hope to have something 36 a commercial product available within the next two years.

单选题One of the questions that is coming into focus as we face growing scarcity of resources of many kinds in the world is how to divide limited resources among countries. In the international development community, the conventional wisdom has been that the 2 billion people living in poor countries could never expect to reach the standard of living that most of us in North America enjoy, simply because the world does not contain enough iron ore, protein, petroleum, and so on. At the same time, we in the United States have continued to pursue super affluence as though there were no limits on how much we could consume. We make up 6 percent of the world's people; yet we consume one-third of the world's resources. As long as the resources we consumed each year came primarily from within our own boundaries, this was largely an internal matter. But as our resources come more and more from the outside world, "outsiders" are going to have some say over the rate at which and terms under which we consume. We will no longer be able to think in terms of "our" resources and "their" resources, but only of common resources. As Americans consuming such a disproportionate share of the world's resources, we have to question whether or not we can continue our pursuit of super affluence in a world of scarcity. We are now reaching the point where we must carefully examine' the presumed link between our level of well-being and the level of material goods consumed. If you have only one crust of bread and get another crust of bread, your well-being is greatly enhanced. But if you have a loaf of bread, then an additional crust of bread doesn't make that much difference. In the eyes of most of the world today, Americans have their loaf of bread and are asking for still more. People elsewhere are beginning to ask why. This is the question we're going to have to answer, whether we're trying to persuade countries to step up their exports of oil to us or trying to convince them that we ought to be permitted to maintain our share of the world fish catch. The prospect of a scarcity of, and competition for, the world's resources requires that we reexamine the way in which we relate to the rest of the world. It means we find ways of cutting back on resource consumption that is dependent on the resources and cooperation of other countries. We cannot expect people in these countries to concern themselves with our worsening energy and food shortages unless we demonstrate some concern for the hunger, illiteracy and disease that are diminishing life for them.
