答案：
本文主要介紹了空氣污染中的微笑顆粒是如何形成和影響人的健康的。
1. b 句義理解題。讀完全文，結合上下文語境，不難看出作者此句話的目的是說：不用研究高深科技的火箭專家（研究），人們也知道，在霧天深呼吸對身體健康不利。
2. a 猜測詞義題。根據上下文可知老年人和小孩是最容易受到空氣污染的危害的故選擇a 項。
3. a 歸納段落大意題。第4段就是講相對小的受污染的風險最終會導致很壞的后果。
4. c 推理判斷題。由文章第一句話可知，深呼吸不一定能夠更加健康。根據最后一段中masks won’t work, as many particles can slip right through.可知b項是錯誤的。最后一段中提到鄉村居住是一種降低空氣污染的途徑，又由文章最后一句people who regularly exercise outdoors near highways may want to consider remapping their route.可推出c項正確。由short-term exposure to traffic fumes tripled （成為3倍） the risk of heart attacks 可知d也不符合文意。
