Test analysis: this question examines the principle of consumption. The products snapped up in the year of SARS haven't been finished yet, which shows that consumption is blind and rational, so view B meets the meaning of the question, and views A, C and D are correct but don't meet the meaning of the question, so the answer should be B.

Comments: the correct consumption principle is: live within our means and consume moderately; Avoid blind obedience and rational consumption; Environmental protection and green consumption; Diligence and thrift, hard work. Avoid blind obedience and rational consumption: consumption should be independent, keep a cool head, avoid following the trend, avoid emotional consumption as much as possible, avoid the tendency of focusing only on material consumption and ignoring spiritual consumption, and make material consumption and spiritual consumption develop harmoniously. The difficulty is moderate.
