1.【答案】B。
解析：The remaining useful life is 45 years from 1 September 20X0 to 1 September 20X5. The excess deprecation is the new depreciation amount of $10,000($450,000/45 years) less the old depreciation charge of $6,000 ($300,000/50 years) which is $4,000. This amount should be debited from the revaluation surplus and credited to retained earnings each year.
