The Timber rattlesnake is now on the endangeredspecies list, and is extinct in two eastern states inwhich it once flourished.
译文：粗鳞响尾蛇现已成为濒危物种，它在一度活跃过的东部两州里已经灭绝了。
点睛：endangered species意为“濒危物种”。which引导的是以states为先行词的定语从句，前面的介词in不可省略，但in which可以用where来替代。注意，如果关系代词在定语从句中充当介词的宾语，介词既可置于从句之首，亦可置于从句之末，但前者较正式。
