听力原文： There is an art exhibition here on campus which ties well of discussions we've had about folk art. It's an exhibition of wildlife art calendars from about a hundred years ago. Like most other folk art, the calendar pictures were not considered to be art in their own days. People just thought of them as a way of decorating a practical object. In fact, the calendar pictures were originally painted as advertising for various companies that made hunting or fishing produces, like guns or fishing rods. The calendars were handed out free to customers to thank them for their business. Most people just hung the calendars on their walls where the pictures faded in the sun and then tore the pictures off the calendar as each month passed. As a result, collectors today place of a lot of value on calendars that are complete and in good condition. Even though the people who used the calendars didn't regard them as art, the original paintings the prints were made from were often of good quality. In fact, many famous wildlife painters created calendar art at some point in their lives. To them, it was way of getting a work reproduced and showed around. One aspect of the exhibit that I find very interesting is the way these pictures reflect changing attitudes toward wildlife. The pictures in the exhibit often portray the thrill and adventure of hunting rather than any particular concern for wildlife preservation. But most of today's wildlife art shows animals in their natural surroundings without any humans in the scene. This modern wildlife art appeals to large numbers of nature lovers, even those who oppose the practice of hunting.

What is the talk mainly about?

A．How artists gained fame.

B．A schedule of art exhibits.

C．One form. of folk art.

D．The preservation of old paintings.

听力原文： The decline in oil prices triggered last week by a row between major world crude producers over output could provide a timely boost to the struggling global economy, analysts believed. Crude prices fell some 15% last week—bad news for the world's major exporters locked in a nerve-wracking battle for market share, [but good news for oil importing western economies that are flirting with recession.] However, major importers like the United States, Japan and the European Union do not want oil prices to plunge to pitiful levels. Ridiculously cheap crude oil would present a new set of problems—destabilizing the Middle East and encouraging wasteful use that would aggravate global warming, analysts say. But for now,[economie managers in Washington, London and Tokyo grappling with a testing economic downturn are happy with reeent development in crude markets.]

The price drop of crude oil is beneficial in that it

A．helps to revitalize the world economy.

B．promotes oil export to other nations.

C．helps to push up the regional economy.

D．provides an opportunity to the oil exporters.

The highest rate of skin cancers is found in teenagers who use sun lamps frequently.

How men first learnt to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thought and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to present those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words. The power of words, then, lies in their associations - the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something increases. Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and vulgar. What is true about words?

：A、They are used to express feelings only

B、They can not be written down

C、They are simply sounds

D、They are mysterious.

Great writers are those who not only have great thoughts but also express these thoughts in words which deeply attract our minds and emotions. This skillful use of words is called "literary style". Above all, a real poet can express his meaning in words which sing like music and can move men to tears. We should, therefore, learn to choose our words carefully and use them properly, or they will make our speech silly and vulgar.

The origin of language is______.

A．treasure handed down from the past

B．a matter that is hidden or secret
