疑难追踪1.As a result, these endangered animals may even die out.(P25)难句解读结果，这些濒危的动物甚至可能会消亡。
die out意为“(动植物物种)灭绝;(风俗、习惯等)逐渐消失，消灭;(火)逐渐熄灭”。

Many traditional customs have died out because they are out of date.因为已经过时，许多传统风俗正逐渐消失。

loss作名词。
意为“遗失，丧失;损失，损坏;输，未赢”。
其动词形式lose。
例如：Did you report the loss of your jewellery to the police?你有没有把你丢失珠宝的事报告给警方?The company suffered a heavy loss as a result of that mistake.因为那次错误，公司损失惨重。
