【原文】 进入21世纪后，知识产权的确认、登记和保护已成为提高企业竞争力的关键因素之一。 【参考译文】 After entering the 21st century, the confirmation, registration and protection of intellectual property rights has become one of the key factors that enhance a company’s competitiveness. 【难点分析】 在翻译这句时，可先找出主干“知识产权的确认、登记和保护已成为关键因素之一”并将其译成“the confirmation, registration and protection of intellectual property rights has become one of the key factors”；然后将“提高企业竞争力的”译成that引导的从句“that enhance a company’s competitiveness”来充当“关键因素”的后置定语。
