Nobody knows exactly how many languages there are in the world, partly because of the difficulty of distinguishing between a language and the sublanguages or dialects within it, but those who have tried to count typically have found about five thousand.
句子到 within it是完整的, but之后的句子是个补充modifier clause. count可以不加them,而且加了them反倒感觉这个指代不清。 虽然知道是指代泛指不同语言,可具体的到底是说languages, sublanguages, or including all dialects 呢? 本来句子就告诉我们这个数法无法精确定义,后面补充只是指出一个大概的范围在5000左右。那这个them到底说的哪种数法,sublanguages and dialects又都是如何定义和区分的呢。作者: sunflower88 时间: 2011-2-22 07:23
