下个世纪,牙医可能要考虑改行了,人们可能会靠吃西红柿或香蕉制造出抗体来对付细菌,因而不需要牙医来钻牙、补牙了。这可不是什么天方夜谭,科学家们正在从事这方面的研究,并且有了相当可喜的进展。 In the next century, dentists may have to consider diverting. People may rely on eating tomatoes or bananas to make antibodies against bacteria, so they don’t need dentists to drill and fill their teeth. This is not a fantasy, scientists are engaged in research in this area, and has made quite encouraging progress.
