空气污染让人郁闷还让人笨?_BEC初级作文

空气污染让人郁闷还让人笨?

Air pollution also significantly inhibits cognitive performance. We found that individuals exposed to polluted air when taking tests scored lower on both verbal and maths tests than when they were conducted under a clear sky.

空气污染还显著抑制了认知表现。我们发现，在接受测试时处于空气污染环境的个人在语文和数学测试中的得分，低于他们在晴朗天空下接受测试的结果。

The cumulative effect of pollution on test scores is even more pronounced than the immediate effect. An increase in the mean air pollution index for three years before testing had seven times the negative impact on scores than did a higher air pollution index on the testing day alone.

污染对于测试得分的累积影响甚至比即时影响还要明显。如果在测试之前的3年期间平均空气污染指数已然提高，其对得分的负面影响，是空气污染水平仅仅在测试当天较高的7倍。

The worse cumulative impact suggests that short-term measures to reduce pollution at times when enhanced mental capacity is needed, would do little to address the longer-term effects of exposure to harmful air.

累积影响更严重似乎表明，在需要较强智力时采取短期措施减少污染，基本上无助于解决暴露于有害空气的较长期影响。

Similarly, though the effects on mental capacity were stronger for outdoor workers than for indoor workers, studies have shown that the smallest and most harmful air pollutants can, and do, enter buildings, so simply retreating indoors cannot spare us the ill effects.
