【英语时差8,16】三手烟（上）

（单词翻译）

Smoking, as we all know, is bad for you. We also know that inhaling¹ other people’s smoke is nearly as unhealthy as lighting² up on your own. Scientists are finding that just being in a car or building where people have been smoking is potentially bad news. When smoke curls off the lit end of a cigar or cigarette, it may seem to vanish. But the nicotine³ particles and many other chemicals in cigarette smoke don’t literally⁴ disappear. They soak into walls, floors, furniture, and even clothing. Beyond smelling bad, this so called third-hand smoke can react with common household chemicals to form toxic⁵ compounds.
