[单项选择]Every profession or trade, every art, and every science has its technical vocabulary. Different occupations, however, differ widely in the character of their special vocabularies. In trades and handicrafts, and other vocations, like farming and fishery, that have occupied great numbers of men from remote times, the technical vocabulary, is very old. It consists largely of native words, or of borrowed words that have worked themselves into the very fibre of our language. Hence, though highly technical in many particulars, these vocabularies are more familiar in sound, and more generally understood, than most other technicalities. The special dialects of law, medicine, divinity, and philosophy have also, in their older strata, become pretty familiar to cultivated persons and have contributed much to the popular vocabulary. Yet every vocation still possesses a large body of technical terms that remain essentially foreign, even to educated speech. And the proportion has been much increased

[单项选择]Two travelers engaged in a warm dispute about the color of the Chameleon. One of them affirmed it was blue, that he had seen it with his own eyes upon the naked branch of a tree, feeding on the air in a very clear day. The other strongly asserted it was green, and that he had viewed it very closely and minutely upon the broad leaf of a fig tree. Both of them were positive, and the dispute was rising to a quarrel; but a third person luckily coming by, they agreed to refer the question to his decision. "Gentlemen," said the Arbitrator, "You could not have been more lucky in your reference, as I happen to have caught one of them last night; but, indeed, you are both mistaken, for the creature is totally black." "Black, impossible." "Nay," said the Umpire, with great assurance, "the matter may be soon decided, for I immediately enclosed my Chameleon in a little box, and here it is." So saying, he drew it out of his pocket, opened the box, and, lo! It was white as snow.

On screens big and small, young heroes like Harry Potter and Buffy, the Vampire Slayer are marked by their ability to transform themselves when faced with danger. Post-9-11, in a world that seems increasingly out of control, such flexibility is more prized than ever. So perhaps it’s not surprising that the classical master of metamorphosis, Ovid, is having a comeback. The ancient Roman poet created a universe full of magical transformations; his best-known work "Metamorphoses" depicts constant change as a creative and inevitable life force. Now a new generation of writers, artists and composers is rediscovering his powerful themes.
Ovid’s historical impact had been vast. In her new book, Fantastic Metamorphoses, Other Worlds, Marina Warner explores on the likes of Chaucer, Dante and Shakespeare.
