这类词有:表示人名,地名,机构名等专有名词。遇到这些词,只要我们能辨认出它是专有名词,就能理解文章而不必知道它的意思。比如在下面的句子中:"In fact", says David Dinges, a sleep specialist at the University of Pennsylvania School of Medicine, "there's even a prohibition against admitting we need sleep." 两个引号之间的部分就不必去管它。类似的还有:"We have to totally change our attitude toward napping," says Dr. William Dement of Stanford University,the godfather of sleep research.
