题目原文:
Did bees (a type of insect) exist on Earth as early as 200 million years ago? Such a theory is supported by the discovery of very old fossil structures that resemble bee nests. The structures have been found inside 200- million-year-old fossilized trees in the state of Arizona in the southwestern United States. However, many skeptics doubt that the structures were created by bees. The skeptics support their view with several arguments.
No Fossils of Actual Bees
First, no fossil remains of actual bees have ever been found that date to 200 million years ago. The earliest preserved body of a bee is 100 million years old—only half as old as the fossilized structures discovered in
Arizona.
Absence of Flowering Plants
A second reason to doubt that bees existed 200 million years ago is the absence of flowering plants in that period. Today’s bees feed almost exclusively on the flowers of flowering plants; in fact, bees and flowering plants have evolved a close, mutually dependent biological relationship. Flowering plants, however, first appeared on Earth 125 million years ago. Given the bees’ close association with flowering plants, it is unlikely bees could have existed before that time.
Structures Lack Some Details
Third, while the fossilized structures found in Arizona are somewhat similar to nest chambers made by modern bees, they lack some of the finer details of bees’ nests. For example, chambers of modern bee nests are closed by caps that have a spiral pattern, but the fossilized chambers lack such caps. That suggests the fossilized structures were made by other insects, such as wood-boring beetles.

是否要用政府资金赞助艺术家?
Professor Diaz
Do you believe that governments should use public funds to provide financial support to artists – for example, painters, sculptors, musicians, or filmmakers? Why or why not?
Claire
I don’t think tax payers’ hard-earned money should be spent on impractical or inessential items and services. Artists should support themselves by selling their work to private individuals and companies.
Paul
I personally think art actually is essential. Lots of public spaces in my hometown just wouldn’t be the same without artwork. The public spaces are simply more enjoyable for visitors because of the artwork.
