It's worth nothing that 翻译
It's worth nothing that Amazon.com sold more Kindles (at least 500,000) in its first year of sales than Apple sold iPods in its first year(378,000).
这句话的翻译是"值得注意的是,亚马逊公司的Kindles第一年的销售量(至少50万台)超过了苹果公司iPods第一年的销售量(37.8万台)."
为什么It's worth nothing that 会翻译为"值得注意的"?而不是"毫无意义的"?
