【单词例句】
◇ Tierno says all that gunk becomes "significant" in as little as a week. And unclean bedding still exposes you to materials that can trigger the sniffing and sneezing, since the microbes are so close to your mouth and nose that you're almost forced to breathe them in.
缇艾诺说，在短短一周的时间里，这些污物就会变得“严重”起来。不清洁的床单被罩会让你暴露在这些物质中，从而引发鼻炎和喷嚏，因为微生物离你的嘴和鼻子太近了，你几乎是被迫将它们吸进去。
