In the famous fairy tale, Snow White eats the Queen's apple and falls victim to a curse(诅咒);in Shakespeare's novel, Romeo drinks the poison and dies; some ancient Chinese emperors took pellets(药丸)that contained mercury(水银), believing that it would make them immortal, but they died afterward.
Poison(毒药) has long been an important ingredient in literature and history, and it seems to always be associated with evil, danger and death. But how much do you really know about poison?
An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison.
The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars(毛毛虫), frogs and spiders. Golden poison frogs, for instance, aren't much bigger than a coin, but their skin is covered with a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.
"Poisons can be bad for some things," Michael Novacek, senior vice president of the museum, told NBC News. "Yet they can also be good for others."
A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol.
The benefits from natural poisons are not limited to just medicine. Believe it or not, many substances(物质)that we regularly ingest(摄入)-chili, coffee and chocolate-owe their special flavors or stimulating(提神的)effects to chemicals that plants make to poison insects.

Happy Rain on a Spring Night
Good rain knows its time right;
It will fall when comes spring. With wind it steals in night; Mute, it moistens each thing. O’er wild lanes dark cloud spreads; In boat a lantern looms. Dawn sees saturated reds; The town’s heavy with blooms. (Translated by Xu Yuanchong) |
When Tang Dynasty poet Du Fu (712-770) wrote this poem, he was living in Chengdu. Sometimes he went to farm in the field. The poem shows his care for farmers.
The very first word, “good”,shows the poet’s joy and love for the spring rain. The rain is good indeed, as it “knows” the proper time to come. Here the poet uses personification (拟人), as if the rain were smart enough to know that it should come in time for the farmer’s busy plowing (农耕) season.
When the rain comes, it appears during the night without making any noise. Unlike the thunder (雷) and lightning of summer storms, the quiet spring rain makes its contributions without seeking (寻求) to be known.
In the night sky,the clouds look dark and heavy,indicating (暗示) that there will be enough rain during the night. Then the poet imagines: tomorrow morning, all of the flowers in the city will bloom (盛开) after the rain.
