5.语言使用

Original: The reading passage introduces a term named rational ignorance, meaning a phenomenon when people deliberately choose to remain ignorant of the difference between products that seem unimportant since they consider it is not worth time gathering information beforehand.

Corrected: The reading passage introduces a term called rational ignorance, which refers to a phenomenon where people deliberately choose to remain ignorant of the differences between products that seem unimportant, as they believe it is not worth spending time gathering information beforehand. (将"named"改为"called"，将"difference"改为"differences"，将"it is not worth time gathering information"改为"it is not worth spending time gathering information")

原因与解释：这里的修改是为了让句子更自然、通顺。使用“called”而不是“named”更符合自然语言的表达。同时，将“difference”改为复数形式“differences”，因为我们在谈论多个产品之间的差异。最后，将“it is not worth time gathering information”改为“it is not worth spending time gathering information”，使句子更符合英语表达习惯。

Revised Answer (140 words):

The reading passage introduces a term called rational ignorance, which refers to a phenomenon where people deliberately choose to remain ignorant of the differences between products that seem unimportant, as they believe it is not worth spending time gathering information beforehand. The professor in the psychology lecture used an example of himself to explain this concept. When he was buying a new car, he took a lot of time researching the advantages and disadvantages of different brands. However, when he was buying batteries, there were several different brands available. Some may last longer and some may be higher in quality. But he didn't ask the salespeople any questions or compare the batteries, as he thought they all cost about the same and may last just about the same amount of time. So, instead of wasting time researching, he just grabbed the first ones he saw and paid for them.
