分析 本文屬于說明文閱讀,作者通過這篇文章主要向我們描述了新的研究發(fā)現(xiàn)維生素B的效果是它可以減少PM2.5對人體的影響,但還要進一步證明.
解答 29.C.細節(jié)理解題.根據(jù)第二段They found that Vitamin B supplement could effectively reduce the impact of the tiny particles (顆粒)on the human body,although they stressed that the research was in its early stages可知新發(fā)現(xiàn)1款維生素B的效果是它可以減少PM2.5對人體的影響;故選C.
30.A.推理判斷題.根據(jù)第二段92% of the world's people are living in places where the PM2.5 level goes beyond the recommended level.So it's urgent to find a solution to the problem可知要進一步研究維生素B的效果;故選A.
31.B.細節(jié)理解題.根據(jù)文章The experiment was then repeated,with each volunteer taking a Vitamin B supplement daily,made up of 2.5mg of folic acid,50mg of Vitamin B6,and l mg of Vitamin B12可知作者通過實驗借鑒Vitamin B的新結論;故選B.
32.D.推理判斷題.根據(jù)最后一段The results emphasized how prevention at an individual level could be used to fight against the damage of PM2.5,the researchers said可知文章最可能在關于健康的網(wǎng)站上看到;故選D.
點評 考察學生的細節(jié)理解和推理判斷能力,做細節(jié)理解題時一定要找到文章中的原句,和題干進行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進行合乎邏輯的推理判斷.
