The pain can stay with you for hours, days or weeks. In some cases, it’s been reported to stay for months.”可知,碰到金皮树会让人难以忘记,因为它所造成的痛苦会持续很久。故选C。 2.D　细节理解题。根据倒数第二段“The scientists were surprised to see three very different kinds of life all use similar poisons. Spiders and cone snails carry poisons because they catch food by stinging other creatures. It’s not clear how stinging helps the gympie-gympie tree.”可知,科学家没有发现金皮树的刺是如何帮助金皮树的,故选D。 3.B　推理判断题。根据最后一段“Though the tree’s sting may stop some animals from eating it, it doesn’t stop all animals. Beetles and pademelons (small relatives of the kangaroo) are able to eat the plant without trouble.”可知,尽管金皮树有毒,一些动物不能吃它,但是像甲虫和小型沙袋鼠就能吃,这说明尽管金皮树有毒,它也是有天敌的。故选B。 4.A　主旨大意题。根据第一段“The rainforests of eastern Australia are home to a stinging (刺人的) tree known as Dendrocnide. Many people call it the gympie-gympie tree—a name given to the tree by indigenous Australians. It’s covered with sharp, needle-like hairs that carry poison. If you brush against a gympie-gympie tree, you won’t forget it anytime soon. The pain can stay with you for hours, days or weeks. In some cases, it’s been reported to stay for months.”并结合文章大意可知,文章主要讲述了科学家对金皮树的研究,且发现了金皮树的秘密, ... ...
